On Friday 1 June 2012, which is Friday last week at the time of writing, I gladly updated my phone through Kies after receiving word of the UK update being available from these very forums. Over the past week, I have noticed that my battery life is considerably worse since my upgrade to the new Android version and, when hearing of people hear who manage up to 36 hours of battery life through this phone, I really want to find out what they are doing exactly. At present, I have set the brightness at 1% (the minimum) and only up it to 40% when out in bright light conditions. At home, I also use the Screen Filter app which dims the screen further (I have this set to 50% of my already 1% brightness setting) and claims to improve battery on AMOLED devices. I also have Juice Defend Ultimate running on "Aggressive" mode along with the built-in power saving mode running as well. Yet, looking on CPU Spy, my phone still does not enter deep sleep which is needed to see a real improvement in battery life as far as I am aware. I have tried restarting the phone and also plugging it back into charge before unplugging it with the screen turned on as many have recommended. Any ideas what else I can do?
Uninstall juicedefender. Its not uncommon that it drains a lot more juice than it saves.
There is must be any Application that is hogging your battery.
Install better battery state... Find that application and uninstall that.
I am getting better battery life in ICS as compared to GB...

I have that app installed, but frankly have no idea how to use it very well. From what I can tell, it is Kik Messenger which is creating a partial wake lock (but I need that to send pictures to my friends), Juice Defender which is supposedly saving battery life and biggest partial wake lock is RILJ or something. But, that is caused from a weak signal and I get that regardless of network at my house. Besides moving, I cannot alter that. As for Juice Defender, I've heard nothing but positive reviews from it. My main aim is to get deep sleep working, but how?
Install Better Battery Stat and check what app is actually causing the problem :

first ,samsung ICS is poorly made ,second you have a high chance of bricking if you wipe your phone with their official kernels so don't do it.
third ,like others said ,juice defender (and any app of this sort) doesn't work anymore (android 2.2 and up) so just uninstall it.
fourth ,not entering deep sleep is mostly due to a rouge app ,and since wiping is not an option for you you need to hunt it down manually ,use better battery status (learn how to use it!!!) and uninstall any apps you don't need.
fifth ,get some knowledge then get rid of crappy touchwiz ROM and install CM9 ,you'll see a huge improvement in terms of performance and battery life.

Okay, well this is my first proper Android device (minus an old second-hand HTC Desire which had awful storage and I used for around one month). Secondly, I do know that other ROMs offer better performance and battery life but flashing them onto my phone is something I'm not very comfortable with and surely it would also void my warranty. I've only had the phone for four weeks and don't want it wrecked already.

I'm fairly new to android as well ,had an S2 (which was so good that I only rooted it ,no custom ROMs) for 5 months before the note and that's it.
but I rooted my note the first day I got it ,and installed a custom ROM less than a week later (was a total noob at the time but I read and learnt quickly) .
then CM9 arrived and I flashed that immediately and haven't regretted it so far.
but I had no warranty to begin with so.....
note that if there is something that can wreck your shinny new note ,then it's amsung official ICS update (read the announcement sticky on ICS and bricking) .
but how experts can explain the fact i face:
With every official and custom ROM i install, even CM9, my note keeps eating battery when in use plugged to the charger... it's unbelievable... I can't understand how it happens.
by the way: i always full wipe before installing any custom/official rom.

Well, is there nothing that I can do to trigger deep sleep or improve battery life on the stock ROM first of all? Secondly, how difficult is rooting and would that void any warranty?

it can't happen ,I'd say you either have a faulty battery\charger or there is someting wrong with the phone itself
the note charges while in use and connected to a charger.

yes you can ,uninstall the violating apps ,learn to use better battery status ,you'll find that there is an app or two responsible for the wake locks ,thus preventing the phone from entering deep sleep.
or simply install every app and game that seems suspisious or poorly made ,and just keep the essential ones.
as for rooting ,it couldn't be simpler if done carefully and to the letter :
1.flash back to GB using PC ODIN
2.root it
3.backup your EFS folder (important , very important) search for it on the forums.
4. install custom ROMs (stay away from unsafe kernels please ,read the sticky thread about ICS kernels)
3. enjoy
use this guide
http://forum.xda-developers.com/showthread.php?t=1329360
yes there is an easy way to root while on stock ICS as per to this guide ,but I prefer you stay away from official ICS for the sole reason that it's dangerous.
remeber the key is to read and read and read ,in a month you could become a pro
on the other hand if you go the lazy way ,you could just end up with a bricked phone
also once you root ,your warranty is void ,though if you're careful you can return it to stock condition and they won't tell the difference
be careful

@Brad387
I have had mine for about 2 weeks. When I turned it on and did the initial setup it had a new software update which was ICS. Since then I have been having issues with deep sleep as well. I turned stuff on and off and it has been totally random what was preventing it from going to deep sleep.
I have done this trick that has been on this forum.
Put you phone to airplane mode.
Power it off completely
Remove battery for 20 seconds or more
put battery back in and power this thing back on
then turn off airplane mode.
This seems to have helped me get into deep sleep. BUT there have been instances of rogue crap going on. Like I was using Google maps with GPS on. When I got home and was done with my traffic mapping I turned off the GPS switch and turned off my phone. I checked an hour later and the battery had died 10% since I got home which was more than when I was driving. I checked Better Battery Stats and it showed that GPS was running that whole time. So I turned on GPS again in the toggle waited a couple seconds then turned it off again and bang it went into deep sleep. It sucks that I have to check crap on it all the time and have become a bit paranoid because the GPS glitch had my phone running pretty hot. Since then everything has been running well and deep sleeping.
There are other things I did do too and the below stuff is up to you if you wish to proceed. I rooted my phone which was very easy...at least for me. http://forum.xda-developers.com/showpost.php?p=20963730&postcount=3 this is what I used with no problem.
From there you can freeze a bunch of stuff you may not use like Social Hub, Accuweather etc etc.You will need Titanium for that though and root access.
I logged out of Latitude too which was on by default for some reason.
If I remember anything else I did I will hit you back here.
Bottom line was finally yesterday I was able to get thru the entire day without needing to plug in so there is light at the end of the tunnel...I hope.
Not sure if this has been mentioned but CPU Spy lets you see if you are getting into deep sleep mode and how much time you are in it along with the other CPU mhz that its running.
Hopefully this can help out a bit because I have been in the same boat and it has been driving me mad. Sorry for all the random thoughts too...I just typed them as I remembered things.

My phone does not seem to enter Deep Sleep, but runs constantly at 200 MHz instead. At present, after turning on the built-in power saving mode (not noticing any performance differs so can't even tell what it does), running Juice Defender Ultimate on aggressive and screen filter I burn around 2% per hour if I just leave my phone locked. Is that healthy?

Actually, there is something you can do about that!
Both Vodafone and Three can supply you with a Femtocell which can greatly improved your signal at home, and uses your home broadband as backhaul.
I know, because I have them!

Battery life of my Note was horrible after upgrade to ICS, and actually already quite bad the last month on GB2.3.6 (all unrooted).
It could get quite warm and often when opening my case the screen was already on.
So I did wipe my phone, reinstalled all apps and battery life has improved immensely.
I see several warnings here about chance to brick your phone when wiping on stock ROM, but not solving the battery drain is of course no option and we don't have a guarantee from Samsung for nothing...

your phone should not be running at 200MHz when you hit the sleep/power button. So if its in your pocket and the screen is off then 200MHz is not healthy. Something is running in the background. Have you tried the airplane mode battery trick yet? What I did when that was happening to me was...turn on the airplane mode, power off the phone, pull out batt for 20 secs, put batt in and power on phone, turn off airplane mode, then go to CPU Stats and clear it, then put phone back to sleep and let it sit for a half hour or less if you cant handle that wait like I couldnt. Go back to CPU Stats and and click refresh and see if it helped and if your phone went into deep sleep.

Thought the title would get your attention.
After upgrading to Froyo, I have many issues, two of which I'll cover here in hope that someone can resolve them.
First issue is battery life. Absolutely horrible after upgrading. Thought it would be the opposite. Can someone please provide some resolution to this issue? I've disabled a number of things said to resolve this problem but none have worked.
The second issue is the accelerometer after upgrading. Most screens end up in landscape view and switching back to portrait is difficult. I have tried to calibrate it but that didn't work. Don't like the huge delay or failed attempt to switch between both on this version. Calibration does not work.
Any help is appreciated...

buy a new battery and a good charger

screen
Why would I want to uncheck that option? I want it to auto rotate but want it to happen quicker than it has after upgrading.
battery..
In addition, the battery is obviously not the problem here. This started after upgrading to Froyo.
Were you using a custom ROM with 2.1?
Are you using a custom ROM with 2.2?
As far as I know, the stock ROM with 2.1 didn't have great battery life either (thought I'm not sure, I rooted my phone the day I got it ). So if you're using a stock ROM with 2.2, you could have the same issue.
Also, if you are rooted, try using SetCPU. Even with the default kernel you can use it to underclock your phone when the screen's off and save a lot of battery.

are you running a task killer? try removing it. Have you tried any of the MANY battery life tricks? Try flashing the update.zip, could have been a messy install. you also could be suffering from useritis.

Thanks for the reply. No, phone has not been rooted. I simply waited for the 2.2 upgrade and can confirm both issues are a result of upgrading. You are right...the stock ROM did not have good battery life. However, after upgrading, it is much worse in comparison.
The g-sensor issue is also a huge problem. With that said, I'm looking for a fix to these two issues.
Thanks,
task killer..
tonyh703,
Yes, I'm running Advanced Task Killer which did not have a problem before. Is this an app that can cause this problem? I'll remove it if so...
You really need to do a little detective work to find out why your battery is not lasting. My battery is actually lasting noticeably longer on froyo. I was using Fresh 1.0.1 before with Netarchy's kernel and would just barely make it through the day of moderate use. Now that I have updated to Fresh 3.1.0.1, I am easily making it through the day with about the same use. Yesterday, I went 14 hours and still had 26% left when I plugged it in for the night. My usage was about 2 hours streaming last.fm, about a half hour of phone calls, about 1 1/2 hours of internet and twitter, about 45 minutes watching video's, and an hour and a half of reading with my kindle ap. To me that is pretty darn good. I have gps on, twitter syncing every half hour, and google sync on, most of my other stuff like email and such is set to manually sync. The only thing I did notice is that the first day after going to Froyo, my battery went down pretty quick, but after a day or two it settled down to the way it is now on it's own. Today I have had about the same use as yesterday so far, and have been off of the charger for 11 hours and have 76% remaining.
As to your other problem, can't say, mine is working fine.
If youve got an led flashlight type of app installed uninstall it they conflict with the HTC LED flashlight. That seems to be the most common problem with people upgrading to Froyo.
Agree on your second point. I wish there was a way to at least lock the screen to an orientation when need. The delay though is ridiculous.
I have also noticed that the delay to type sometimes is severely long causing me to retype the words a second time before they appear in the screen.

FWIW - I found a little trick on a forum somewhere that allegedly came from HTC techs...
It goes like this - first, charge your phone as normal (phone on, 8 hours)
Then, after 8 hours and the phone reporting fully charged status, take the phone off the charger for about 3 minutes (just enough to slightly discharge it) and then turn it off (power down) and put it back on the charger for an hour or so.
Then, take it off the charger and turn it back on.
That's it! It sounds a bit ridiculous, but I think the cited reason was that whenever you install a new ROM, the "system" needs to understand when the battery is truly full and this trick helps to recalibrate and ensure that it is.
I really don't have any way (nor the desire) to verify the science behind this, but I did it myself after the horrible battery life I got with FroYo.
About a week out now and my battery is behaving completely normally, and possibly better than with 2.1, though only marginally if that...
Give it a shot - if it works, there you go, if not... Well it's not like you've lost anything.
Good luck, though YMMV.

have any of yall had a long delay when putting in a name for the reciver in sms? I kid you not it takes almost 3 to 5 sec for it to pull up a name and phone number from my phone book.
Its sad that you need to do "tricks" to get decent battery life, because most people expect it out of the box. Yes you can apply a custom rom with a undervolted cpu, but that shouldnt be necessary. I personally love doing all that stuff, but the majority of people are completely ignorant to these methods and might return their phones because of battery life, but for you people on here...BAKEDSNACK 1.2.5 with the latest of his kernel..amazing battery life.
Get rid of that task killer!! Froyo does not need it... Not to mention none of the task killers support Froyo correctly. Uninstall it, try using Froyo without it.
I recommend getting rid of the task killer and go without system panel lite. It works with froyo without any problems. I also recommend letting your battery completely die out before charging it again.
My Evo worked without any issues after the update to froyo. Also, if you are a widget fanatic, I recommend limiting the amount yo u use . The reason being that everytime you unlock your phone and scroll from one page to through next, you are loading said widgets into memory which help to eating up the battery quicker.
Also if you have a lot of things updating in the background, that can kill your battery quicker. I'm always on my phone and get anywhere from ten to fourteen hours of use. I also use a cpu manager to extend the life of my battery when not in use.

DO NOT DEPLETE YOUR BATTERY COMPLETELY!! These are Li-ion batteries. Depleting the battery too much can damage the cells. Discharging the batteries 100% before charging to avoid memory effect is a phenomena unique to Ni-Cad batteries. If a Li-ion is discharged too severely, it causes an irreversible reaction inside the cell that prevents the battery from holding any charge at all. This common in laptop batteries.
To the OPs issue, do you have the latest Facebook update (1.3.1)? Version 1.3.0 had an issue that was keeping the phone awake eating up battery life.

I could see how this could be bad if you discharged it completely every single time, but every phone ive had including the iphone, it has been specificly stated many times to COMPLETELY DISCHARGE THE BATTERY ATLEAST ONCE A MONTH
Still no luck...
Guys,
I have removed the task killer and have removed the other LED Light utility. Still having battery issues. Any other suggestions please??
Also,
What about the accelerometer? Having many issues with it. First off, when a text msg comes in, it automatically shows in landscape. Phone switches to landscape fine but it is very difficult to switch back to portrait.
Any other help is greatly appreciated.
Thanks,
I've been seeing a lot of posts on crap battery life around here, and I was chasing my tail about some of them as well, following a lot of misinformation even by senior members. I think I have a good handle on it now, and picked up most of these tips from these forums, so I'm not taking credit for these ideas, just collecting them in one place. Some of my suggestions assume you have root and Rom Manager (see the Tips and Tricks sticky thread on how to get them).
1. If your battery drains in less than a day on standby, you probably have a bad flash of the JI6 modem (either from the OTA update or from a ROM). Flash the JI2 modem from here "www dot teamwhiskey dot com/home/downloads". If the flash fixes it, you may try going back to JI6 if you want, and it may stay fixed. I went back to JI2 and didn't bother going back to JI6, but it has worked for others. With JI2 and 3G on I get just over 24 hours in normal usage.
2. The #2 battery drain on standby is 3G. I turned it off (Settings/Wireless/Mobile networks/Network mode/GSM only) and my phone lasted for 40 hours on Edge with light usage (few phone calls, messaging, quite a lot of web surfing, 2 hours of podcasts). Didn't even feel too slow (I get 140kbps on edge). Can anybody suggest a really good widget for turning 3G on/off? I use the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.
2.5. WiFi always on is a huge battery saver! It keeps 3g off. I can easily get 3+ days with light usage on my home wifi. Settings/Wireless and Network/Wifi Settings/Menu/Advanced/Wifi Sleep Policy/Never.
3. Don't need a task killer. I wasted all my time killing tasks trying to chase down my crappy battery usage, but since I fixed my modem and turned off 3G I know that the 3-5% CPU usage at idle does not hurt my battery. Taskiller for me was actually hitting the CPU constantly, lightly but for no reason, so I got pissed and uninstalled it.
4. Install a CPU usage monitor like Usage Timelines. It sits in the notification bar, very easy on the battery, but tells you if you have a rogue app pegging your CPU and draining your battery. These are the only apps you should be worried about killing. Astro File Manager has a task manager that shows CPU usage for each app, so you can kill the rogue one. I shoot for about 5% cpu usage at idle (at 200mhz - at 100mhz it would be a bit higher).
5. The app Autostarts lets you disable any app from starting on boot or other events like connectivity changes. This is not strictly necessary unless you have a lot of crap apps installed on your phone and they like to start themselves and waste CPU time behind your back.
6. If your battery reads less than 100% as soon as you unplug it from the charger fully charged, or your battery meter sits at 100% for a long time after you unplug it, you can recalibrate your battery meter. To recalibrate: 1) charge your battery to full, 2) unplug, 3) reboot into Clockwork Recovery and 4) Wipe battery stats.
7. There is No Such Thing as "battery reconditioning" (for all intents and purposes). The above procedure only RECALIBRATES you battery METER to read on a more linear scale between full and empty. It DOES NOT make your battery last longer, period. Whoever tells you that is a moron. If your battery is dying in 6 hours, doing any amount of calibration will not make it last longer (I've tried).
8. I wouldn't be too worried about undervolting, overclocking, kernel tricks and superawesomefast ROMS. The CPU drain at idle is so minuscule (as long as you don't have rogue apps) that those things make precious little difference. Like I said, the biggest drain is 3G and other radios. Having said that, I run Bionix 1.9 with the JAC kernel. It drained my battery in half a day at idle until I flashed the JI2 modem. With JI2 it suddenly started lasting over 24 hours, and once I turned off 3G, over 40 hours. I like this ROM and see no need to switch, it's very smooth. But you should be able to get similar battery life on a stock Vibrant.
9. I have GPS on, WiFi never sleep, auto-brightness, and a few widgets on like Weather and friend updates. I have no fancy settings, literally just turning off 3G (or wifi on, which is the same) got me 2-3 days. So I wouldn't waste time fooling around with magic settings (other than wifi never sleep), battery saver apps, etc.
10. If your screen is on all the time and you're playing games nonstop, you're draining your battery quicker than any of the things I mentioned above, so you probably don't care. In that case an optimized ROM/kernel is probably your best bet, especially JIT in Froyo. You can probably save on screen brightness as well.
If you guys have any other tips I'd be glad to add them to the list, but I hope this gives you an understanding of where your battery life is going. Basically: bad modem, 3G, or rogue apps.
Also, I hope this will put an end to trolls calling people whiners for complaining about battery life and saying unproductive **** like "you're a whiner" or "the Galaxy S is just a battery hog, live with it". It's not, you don't have to live with it, nobody should have to, here are your solutions.
Good luck.
A few things I do to help with battery life is:
Disable Audible touch tones
Disable Audible selection
Disable Haptic feedback
Disable SD card notifications
Set animations to NO animations
Uninstall media hub if you dont use it
Disable auto brightness adjustment
Disable power saving mode
I disable the last 2 and just swipe the notification bar to adjust brightness. Granted these items really only work when using the phone but I can go about 2 days of normal use without a charge believe it or not.
yeah disabling 3g has always been the best option for people really, really concerned with battery life.
But it's kinda hard to tell people not to use 3g on their brand new 3g capable devices.
You may want to add how to test if you battery is bad. If you use you phone repeatedly while it its plugged in you risk overheating and damaging your battery. Signs that unitas is the case are very quick drain and long (7 hours) charge times. You can easily test and see if your battery its damaged. Remove it from your phone and place on flat surface (e.g. Counter top) try spinning the battery. If it rotates easily and quickly you battery is bulging, this is a sign of damage. Time for a new battery.

Thanks to the OP and other contributors in this thread.
I flashed a ROM with the ji6 modem and battery life has been noticeably ****ty since. Example - this morning I unplugged my phone at 7:30 am. 100% charged. It's 10:21 am and my phone is at 75%
In the last 3 hours I browsed the web for 10 minutes while having my coffee and a smoke before heading out to work. Blue tooth was on for my drive, and I've sent 2 text messages. Aside from that my phone has been on stand-by since I unplugged it 3 hours ago.
I'm going to try to flash back to ji2 tonight as the battery usage was definitely better. Will also look into the 3G thing.
Thanks again.
You forgot to mention the two DRM and one downloader services that run resident on JI6.
These were the cause of my reduced battery life after I upgraded. Killing & removing these processes restored my battery life back to normal

I just tried this - switching 3G off works fine, but switching 3G back on didn't work for me. I had to re-boot to get 3G back so this is a no-go in my case.
I know how to kill the processes for the DRM and downloader but how do I remove them?
OP thank you for putting together the list. But I've never seen the point of doing all this. Its like getting a lamborghini and only driving 40mph because it you don't want to waste gas, whats the point? Either get a second wall charger to charge at work or a car charger. Heck even get a second battery if you are out for a long period of time.

You don't need to disable 3g.
The point of my post is to avoid people wasting their time with tweaks that have little to no effect on battery life. I'm telling people that they're wasting time killing apps and optimizing cpu usage and twiddling their settings when the radio drains most of their battery on standby anyway.
Meaning no matter what changes you make, you can only hope to improve your battery life by a tiny amount, because any other effect is overshadowed by 3G.
Put another way, you will NEVER get battery life much longer than a day if you're on 3g, so you're wasting your energy trying all kinds of tricks.

For me the widget did nothing. But it seems like it's not even supposed to turn the 3G radio off, but ALL APN network traffic. Did I miss something? It won't save battery power as long as the 3G radio is on.
I went back to the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.

While i understand the idea behind this thread, your conclusion is simple.
If you use the phone as a smartphone, it will eat up your battery no matter what.
I personally go through two batteries and some a day. (they cost about 12 bucks in ebay, and they work just fine)
The price for saving battery is not using the phone, and having a 400 bucks phone just for show off is just silly at least.
If you have a phone like this is to use it. At least you can change the battery not like some other devices......
I understand that task killer is useless, but do any of you use Autokiller (memory manager) ?
That's kind of a redundant question because even if you do not use the app, your phone is still performing the functions. The app just adjusts the settings. But to answer your question, using a memory optimization tool such as AutoKiller is 1000% more efficient than using a Task Killer. I don't think it effects battery much, but works wonders on performance.
There's no 3g-off widget because apparently in Android there's no way to do that through a direct command. I also use the Curvefish widget, and you are absolutely right about turning off 3g to save battery. I normally do so when I'm asleep or if I'm sitting at my desk next to a computer (why do I need fast data on my phone when I have my computer right here?).
The other thing I would recommend is AutoStarts. There are way too many apps that open themselves up at bizarre and inappropriate times. Autostarts is an easy and painless way to see which apps do this and keep them from opening.

Great battery life comes to people who hardly use their phones. Guess I need to get a netbook. Will prolly get a netbook or 3g laptop + skype and ETF my phone soon. These battery woes are show-stopping.

Losing 4% an hour on standby when you're not using the phone is unacceptable. Samsung screwed something up with the JI6 update. Most people think it's because of the stupid Media Hub. I think they are right.
People are not complaining about the poor battery life from using the phone. They are complaining about the slow battery drain even when they are not using it. ~4% an hour adds up fast. Vibrant is supposed to have 450 hour (18 days) stand-by time. That's what is rated. But people are getting 24 hour (1 day) stand-by time after JI6.

I'm not ready to sign off on this idea. For me simply flashing JI2 over JI6 fixed it. For some people flashing JI6 back over still left the problem fixed. I still have those processes running on JI2 and my battery life is fine.
The other reason I'm not ready to recommend wiping out those DRM processes is that apparently it stops the bundled Avatar movie from playing, and might affect other things that users may get pissed about. I've read that killing the downloader process people are talking about kills the market. So I really wish those people advocating that solution would figure their **** out and provide exact steps for the fix (right now their posts are really vague like "kill the processes that are named something like this" and not well tested; in all my research I didn't find the exact name of the "downloader" process).
Is it possible to flash the ji2 modem without root? Wishful thinking, I suppose..
(I'll preface this by saying that I am well aware there have been a million threads about this, I'm sure, and I'm even more sure that there will be a million more. And I have searched, and searched, and searched some more, and I still feel the need to post this question. Flame me if you want. I'll use the flames to heat up some tea, or something.)
I bought my phone last Thursday, it got lit with service Friday. I went over the weekend and into Sunday with stock ROM/kernel, and decided to mix things up by rooting my phone and using the MixUp kernel to see if I could get better battery life.. and it didn't work too well. I mean, life went up a bit, but not noticeably so (maybe twenty or thirty minutes?)
After that, I flashed Syndicate, which had Xtreme Kernel. I calibrated the battery as instructed inside of Clockwork and went with it for Tuesday.. took it off the charger at 8:00 and it died around 4:00. Kept the same kernel and flashed Epic Experience and the attached JuicePlotter shot is where I am at right now.
My usage today has been light browsing and that's basically it. I've got the processor underclocked to 600 with SetCPU, and JuiceDefender and Superpower have been preventing any data from going on when my screen is off, and for the last two hours I've been listening to MP3s using the in-built music player.
This makes me cry considering there are people on here saying they're able to get much more life out of their battery, even with BT and WiFi etc. I'm aware that each phone is different and all that, but still.
All that said, is there a problem with my phone/battery, is this par for the course with the Epic, or should I just stop whining?
Thanks in advance for any help/insight.
A couple of things...get a task killer app so that you can kill the drm process which eats up a ton of battery, calibraing your battery takes 2 or 3 times going from full charge to zero and also, since its a new phone it takes charging to full and letting it get down to complete zero a few times before you will see better battery life no matter what else you do
Edit: oh and also definitely do the airplane mode toggle as well

Also, for each new Kernel you flash, you have to calibrate the battery.
Charge it to full, boot off, boot up in Clockwork, go to Advanced and Clear Battery stats. Reboot the phone, use it until it runs dead and shuts off, than plug it back in and charge it to full with the phone on.
Every time you flash a new kernel, you have to do that process so the battery calibrates to that certain kernel.
Also, try Baked Snack, it gets the best battery life for 2.1 ROMs.

Wipe data/cache

I have to have a car charger if I go anywhere. This phone dies so fast with normal usage. Do anything crazy like turn features on, surf the web, or increase brightness, and I am lucky to get 2 hours. I have multiple batteries, both have the same result.

2 Hours..? Whaaaaa? Lol.
When I calibrate my battery, I turn EVERYTHING on, screen brightness all the way up, Pandora running, every widget I can fit on my screens set to update at their quickest setting, screen set to 30min (Though I never let it shut off). Bluetooth, GPS, 4G running (I don't have 4G here, so it just keeps searching, which drains it more than if it was connected). And running the Maps Live wall paper to use GPS.
When I do all that, I can't get it to even die under 4 hours.
Hopefully you were exaggerating with saying 2 hours lol.
Thank you guys for replying!
Sh0wNuF: I killed the DRM service today and used ATK to kill errant processes throughout the day today to no avail. I also used the airplane mode toggle to try to limit my time without a signal.
SemiGamer: Thank you! I did do the clockwork step as I said in my first post, but I will try to install BakedSnack and get back to you guys as to the battery life.
From the looks of that juiceplotter graph, your data is constantly on and destroying your battery. What is the point of having juicedefender if the data is constantly on?
If you set up the phone properly, and there are a MILLION threads on this which state a MILLION times to disable DRM and toggle airplane mode as a mere baseline beginning, you should lose at most 1% an hour when the phone is idle without a data connection and the screen off.
Now it looks like you probably have the data on constantly with emails rolling in, facebook auto updating every 5 minutes, weather checking every half hour and other things that are just destroying your battery life. If you need your phone to do all that nonsense, then you will be crying for the rest of the time you have it.

Thats fine, but your data aint off. Look at that graph you posted. Every little blip is either data being accessed or the screen turning on. The line should be smooth if there is no data and no screen on.
So there are two options, either you are constantly using the phone and its the screen killing the battery, or you have juicedefender set up all wrong and its the data killing the battery.
If I remember correctly, any spike below the line is data, either wifi or 3g and any spike above the line is the screen turned on. So from the looks of it your data is literally never turning off and you are checking the phone and turning the screen on and off pretty frequently.
What are your settings in juicedefender?

I have almost identical batter results as you. I do use the phone fairly often to send messages but the screen brightness is all the way down and I use set cpu on the froyo beta leak. I reset battery stats and also (perhaps you could look into this too) checked spare parts for any rogue programs. Does yours say the screen takes up most of your battery even if you barely use it?

I would up the Schedule to less often and turn off the traffic toggle. Also, I wouldn't doubt that your phone is never going to sleep. If you have spare parts check the Battery History. If you listen to music with the phone, the service started by the music player, CorePlayerService, keeps the phone awake constantly for me. I ended up making a simple kill music widget using tasker to fix this issue.
I bought a wildly overpriced Samsung stand/battery charger from Amazon. My wife & I each start the day with a charged Epic and a spare battery. No worries

When you say much better battery life exactly how much? My battery dropped 20% today while not being used and Display was still at 60% (I turned the alarm off twice). I'm running the Quantum ROM which could have something to do with it but the battery is horrible for me. I can't get more than 8 hours and that's if i barely use it. I have spare parts and no apps are partially waking it. Just Wifi and sync. No GPS, brightness all the way down. The main thing that bothers me is that display is always #1 even if i don't use the phone at all. Any thoughts?
I've ran both Quantum and Viper Froyo roms and aside from making my phone hot enough to fry eggs, the battery life was not good.
As far as battery life goes, I'll start with the obvious stuff.
1. Turn off GPS, Bluetooth and 4G. 4G is a complete power whore.
2. As for wifi, turn it off unless you are in a bad coverage area for cell data. If you are connect to wifi and set Spare Parts to never let wifi sleep.
3. For DRM there are 3 files you need to remove that will prevent it from running / reinstalling and they are DrmProvider.apk, DrmUA.apk, and SisoDrmProvider.apk.
4. Toggle airplane mode every single time you reboot without fail.
For a true test of whether your phone simply needs to be returned as "defective" you should wipe the device, dont setup a google account and let it run for a day after executing steps 1-4 above. It would be best to an apk for Spare Parts and SDX Stock App Remover on your microSD that could be installed using My Files. If you still have problems take the phone back to sprint (after restoring it to factory of course) and tell them it is defective.

Here's a JuicePlotter graph from today for comparison from my original one yesterday.
I still wonder if it wasn't going to sleep because of PowerAMP and I didn't underclock today like I did yesterday.
There are a few other physical issues with my phone (slider seems a bit loose compared to my other phones: if I swipe with slider closed with a bit more pressure than usual, I can feel the screen move up and down; screen seems to slightly come up a bit when phone's tilted a bit, taps make you feel the screen go back down) that also made me want to consider exchanging it on top of the battery issue but if I'm getting good battery life I don't think I'll mess with what works, unless anything gets worse.
I'll post everything I've tried and everything that's gone wrong here.
So initially I purchased this phone off of a friend nearly brand new, the screen had broken and had been replaced. Otherwise the phone is in perfect factory condition.
I unlocked the phone, and am using it on Rogers. APN settings working perfectly.
I installed GOLauncherEX on the phone as Motoblur wasn't doing it for me.
Battery life was crap (lasting hardly 3 hours and dying while I sleep). I found that Motoblur HOME had been running alongside GOLauncherEX. At first I simply uninstalled the third-party launcher, but then opted to grab LauncherPro+ and HomeSwitcher. This dramatically improved battery life.
Lately, I've been having issues once in awhile again. Mostly if I leave the phone unplugged while I'm sleeping (fully charged when unplugged) and we'll use the timeline 3am - 11am. It would either die completely or drop to around 15%.
As long as I could have enough charge to last me through work, I was fine with this as it was way better than what had been happening before.
This morning something extreme and unexplainable happened.. and it's the first time I took a look at the battery usage meter to see what had happened. Picture is below.
If someone could offer some tips or help that would benefit me even the slightest, it would be very much appreciated.
My bad for sneaking a link in, but it was the only way to show the issue.

Calibrating is something you may need to do after flashing a ROM, you can search and find a guide or you can use this app.
I have not flashed any new roms and I don't intend on doing so, but I'll check out the app you posted.
Thanks for your help,
any new ideas are still welcome.
The benefits of battery calibration are not limited to only if you flash a new ROM. Battery calibration should be the first thing you try if you are experiencing battery troubles imo, and there is allot more in depth information in the guides you could search for.
There is one more thing I can think of you can try, download Watchdog and see if there are any malicious or poorly written apps burning up your cpu/battery.

Do not use 1.97 radio and don't use task killers. 2.3.4 gingerbread does a much better job of killing tasks than Froyo did and it's unnecessary. Also, turning off background data is not necessary.

I would say it is. Apps including google will try and update and locate your phone via 3g and gps when its sitting there idle. Its not necessary if you only install apps that dont use background data, or disable them individually but some dont allow it.
I still was able to get 15 hours with data enabled and over 30 with it disabled. There is a huge difference there. I just have to open my yahoo now to update it which I dont mind.
While I appreciate everyone's replies and help, has anyone actually looked at the picture I posted?
As much as I am most definitely interested in prolonging my battery life, that picture is showing a sudden drop from 70% to completely dead, idling, screen off, while I'm asleep.

I would purchase a new battery from Motorola, It looks like your battery has one or more bad cells in it. Only thing that really explains it. Even with everything turned ON as far as data - the battery should not drop that far that fast.
i'm not entirely sure whats going on with the charge level dropping so sharply. Either something is draining your battery big time or the readout when it says 100% is incorrect.
I had issues with the battery up time as well. In my case, the battery wouldnt last more than 8-9 hours. I had to charge it two times a day. Once overnight so its 100% when i go to work and again as soon as i get home. If i charged to 100%, unplugged and went to bed, it would be at 15-20% when i woke up.
The last time i went abroad, i left the radio turned off completely. I noticed that the battery held its charge for about a day and a half.
Now i did root, unlock the BL and install CM7 on my phone. It seemed better but not that much. After i setup the phone to NOT use my 3G data connection while my wifi was on, i noticed that i was getting great battery life when i was at home but still rubbish at work.
I'm doing a test right now to see if this makes a difference or not. I have turned off data on my phone all together this morning. I charged it to 100%. Normally after 6 hours at work, my phone is at about 30-35%
Right now its sitting at 75%
the 3g is whats killing the battery, on my phone anyway. I will see how long the battery lasts without turning on my data at all. Then i will compare that with how its like with background data turned off.
I would suggest you try re-calibrating your phone's battery, i use battery calibration from the market. Then either turn data off altogether like i have or just turn background data off as the others have suggested and see what kind of a difference it makes.
While i realize you dont want to, it may help further to have a ROM like CM7 installed as it wont have all the bloatware that can further reduce the performance of your phone. You should definitely give turning the data off a go to see its the culprit before you go spend money on a new battery which may or may not fix the problem.
Best to isolate the root cause before you spend money on fixing it. If turning off the data doesnt do it, then you very well may have a battery problem.

i'm not entirely sure whats going on with the charge level dropping so sharply. Either something is draining your battery big time or the readout when it says 100% is incorrect.
I had issues with the battery up time as well. In my case, the battery wouldnt last more than 8-9 hours. I had to charge it two times a day. Once overnight so its 100% when i go to work and again as soon as i get home. If i charged to 100%, unplugged and went to bed, it would be at 15-20% when i woke up.
The last time i went abroad, i left the radio turned off completely. I noticed that the battery held its charge for about a day and a half.
Now i did root, unlock the BL and install CM7 on my phone. It seemed better but not that much. After i setup the phone to NOT use my 3G data connection while my wifi was on, i noticed that i was getting great battery life when i was at home but still rubbish at work.
I'm doing a test right now to see if this makes a difference or not. I have turned off data on my phone all together this morning. I charged it to 100%. Normally after 6 hours at work, my phone is at about 30-35%

I'll definitely try everything you've mentioned, I did calibrate my battery since I first started this topic. I'm not sure if there's a difference, if there is, it isn't noticeable. My phone died last night, and I charged it overnight again so I haven't had a chance to see if what happened the other night will happen again. Soon enough, I'll post details if I notice anything peculiar.
Since you said you bought the phone off a friend I would like to make sure you have the right battery.
The battery "must" be of the following to show the right charge level, otherwise it might appear the battery discharging very quickly.
The part/model no.: SNN5893A
Manufacturing Date: ??/April/2011 or onwards
In regards to the poster above who mentioned shutting off background data, my phone lasts 17-19 hours running CM7 with nothing frozen, background data on, and I record quite a bit of video + pictures every day. I don't use task killers either. So I'm thinking that maybe the background data thing is either actually covering up a radio problem, a carrier issue, previous ROM information leaking through, or a faulty battery as stated above that could possibly need replaced.
Hi all,
Having just bought a Yotaphone 2, latest model 801 processor and with Lollipop installed, I was impressed with it... lovely screen, sharp response, great display on the back ....until I realised that battery life on the EPD or indeed doing nothing was (and is) terrible.
This somewhat negates the point of having the EPD. Because whether you use the EPD or not, as others have found, the processor seems to be spending 100% of the time doing something like trying to connect to Google headquarters to report my unethical swearwords as I look at the battery level heading south.
To try and make sure the phone was using the least power, I went through all the running apps and services and terminated as many as I could, turned off things like Yotafit tracking, turned off the service that sends all your contact details to the Kremlin, and so on... then, I turned on the Yotaenergy mode and despite that, we are at less than 24 hours with virtually no phone usage at all. Fully 50% of all the energy according to the battery stats is being used by Android System and Android OS processes when the system is in standby. And the historic battery screenshot shows that the processor is active 100% of the time., even though the phone has not been touched. (sorry, not attached, I'll post at some point, but its not very interesting)
So, does anyone have any clues about how this can be fixed? I have seen screenshots where people have shown that their processors are not active the whole time, and I imagine they have Lollipop? I have heard Lollipop has got some kind of bug which means that data connections are live the whole time, not sure if this is related.
(This might explain the sudden appearance of half price devices on eBay around six months after launch in the UK.)
Many thanks in advance!
YotaDevices has acknowledged the problems on Lollipop battery life, which is the reason they won't be shipping devices coming to USA preinstalled with Lollipop, but with KitKat. Now that I've played around with the EPD and created some widgets/applications for it, I can spot many places where things can go wrong in maintaining battery life and still keep things working.
Personally I've been lucky with the battery life on all versions of Android. When I updated to the last version of Lollipop (firmware 1.44), the phone did show poor battery life for hours after the installation was finished, before calming down to the promised 5 days stand by. Are you on the very last firmware? (Settings - about phone - build number)
As a last resort if your device won't settle down, I guess you could roll back to Kitkat, which had a very good battery life for pretty much everyone. You can install it with Yota's flasher tool: ftp://fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe
Just carefully select your own region and then the last version of KitKat (4.4.3) they offer. As you are rolling back from one major version to another, I would suggest flashing pretty much everything. You will lose your data.
Yota has said that they are working on bringing Lollipop 5.1 or 5.2 to Yotaphone 2. Let's hope that that works better.
Thanks that was very useful. The question is, will Yota do another build ... or build another device? I'm hoping the Y2 has a bit of life left in it yet and they do launch in the US - it can only help the development community!
I reset back to factory/Lollipop last night as it was eating battery so fast I could not believe it, and I am on the latest build 1.44EU (and was before). Since then.. it doesn't seem to be misbehaving so much, but it does seem to insist that the WIFI is on (when it is switched 'off' in the settings) by 'on' I mean the battery usage recorder... I wil take your advice and 'take it slow' for now, but may flash back to Kitkat if necessary. It is a bit tedious having to reinstall all your apps by hand but this seems to be the only way to ensure it is relatively clean.
The screengrabs below show the phone doing nothing at all in Yotaenergy mode - per first post.

I am quite confident that they will release updated Lollipop sooner or later. They don't have the resources to piss off all their customers just yet.
Your Wifi still does some scans on its own for Google's location service, even if it's not enabled. You can disable this feature in the advanced wifi settings. But that is not the cause of your battery problem. Basically your device is awake all the time, meaning something is holding a wake lock. And by something I mean one of Yota's EPD compoments, which are counted as part of "Android OS" and "Android System" - your biggest battery hogs. It could be one of the EPD widgets that is misbehaving, or it could be some specific combination of them, or just something out of your control.
You could try removing ALL the widgets from the rear screen from Yotahub, then restart the device, and then let it run for an hour with the screen off. Then check the detailed battery log if the device went to sleep or if it was awake. If it went to sleep, you can try adding widgets back one at a time, and then check again if the device sleeps. Basically all the widgets which update periodically hold a wake lock momentarily (time, battery, calendar, weather etc). Of course if the problem lies on Yota's EPD framework, then this wont help at all.

Agreed, I suspect the YotaFit app going bonkers despite my efforts to kill it.... or the Yotagram service, the thing is, looking at the Yota specific apps, you don't really need them, as you can flip the screen with the Yotamirror, and then use any Android app. Sure it would be nice to have notifications on the EPD, but my main focus for this phone is use in bright daylight, and long battery life, not to actually look at the thing 24x7 so I can respond to emails every 30 seconds.
At this point though I'm just trying to determine how bad the underlying hardware is. The GPS on this phone seems to a bit flaky, as does the basic reception of mobile signal. (And I'm not using a metal bumper.) So, I'm happy to flash back to KitKat 4.4.3 to try and give it the best chance..
So, any clues/links about the Yota flash tool? I've put the phone into USB debug mode, installed the flash tool on my windows 7 desktop, and installed ADB/Fastboot as well, but at this point I'm having a bit of an android driver problem, and ADB can't see the phone so that probably explains why the Flashtool says 'waiting for device' when I fire it up. I will go digging to fix that, but I assume that the Flashtool will do all the stuff like putting the phone into bootloader mode, unlock etc...

The widgets I'm running at the moment without any problems are Time, Mini Calendar, weather, battery, and communications (the small widget which shows phone calls, notifications and sms). And of course my own widget.
The best way to make sure there are no useless services running is to root the device and uninstall them completely, but that's another story.
For the flashtool to detect the device, you need to boot it into download mode manually. The easiest way is to turn off your device and plug the usb in while holding volume down -button. The screen will show "download" or something in very small white text. After that the flashtool should find the device. You probably don't have to flash the user partition (it asks for it separately), i.e. the simulated sdcard section which holds all your photos, documents and music.
Edit. And when you have kitkat installed, the first thing you might want to do is to disable automatic system updates. Otherwise it will nag you about the Lollipop update all the time.
I've been facing similar issues and am considering a downgrade when I have the time. I'm really disappointed in yota and won't be buying their next device.
I have found this thread useful, you may too.

thanks gents, oddly, the advice to let the phone 'calm down' seems to be working. I decided not to revert to KitKat (yet), as every day I use the phone the battery life seems to improve. Yesterday it was down to 40%, today 60% after about a days use. I'm thinking a week of running in will give it time to stabilize. I would love to root the phone but I want to use the Good app, and that doesn't run on rooted phones... (shame but I guess that's the flipside of working for a big corporate for you!)

Try putting the battery widget on your epd. If it shows 5 days remaining when you are above 85% and you don't use the phone, then the device works as advertised.
That Good app sounds like a real killjoy. There seems to exist some Xposed modules to disable the root check, but they seemed to be rather finicky to setup and very easy to mess up.
I was suffering from terrible battery life after the lollipop upgrade and the EPD battery widget was never showing much above 1d anymore. After much research and tinkering, it has now improved and I am seeing greater than 3d again. I think the culprits were maybe google fit tracking which I have now turned off and I also de-installed and re-installed the google play services updates which is a tip I saw in an android forum. I also over the last two days have received several yota widget updates which may have also helped. At least for now I am seeing a comfortable day's use again!
I experienced poor battery life out of blue again. I went through all the settings, cleared dalvik-cache and cache partition, tried disabling everything, but nothing helped. It only showed <1 day battery life at 100%.
But then I went to mess around in the developer settings, and when I set the animation scales from 1x to 0.25x and enabled "Force GPU rendering", the battery life returned instantly to 5 days.
Just thought I'd add this to the list of things to test out if someone's experiencing poor battery life. The forced GPU rendering might have some unexpected effects on some software rendering based games.
dont know if this will help but just seen some of the new features of android m "marshmallow" one of which is doze and there is a separate app available on play store for this. i have installed and it has helped battery life !!!
I was going through terrible battery life after Lollipop as well. Suffered, tinkered, tried various things. Eventually I just said screw it, backed everything up and factory reset it from recovery. Since then it seems like it's almost back to it's old self. Obviously having root and using some kernel control apps, greenify and some other things helps it but It will happily do at least a couple of days with little-normal usage. Still don't think it's as good as KitKat but it's not too far off. The EPD really does help spread battery out too.
I did the same thing but a 3 weeks on, the battery is as shocking as ever.
Today, on battery since 0730, now @ 1115 51% and 3hrs left!??
No obvious apps causing battery drain, just google services!

I have had the phone nearly a week, and these are similar figures I experience. What's the point of the epd if my battery dies by lunch!

I think it is something with Android 5.0 that is causing the drain issues. I can go anywhere from half a day to a week with good batteyr life and then it will randomly start draining again. Some background activity seems to hold a permanent wakelock and will not let go of it. I am unable to pinpoint what app is creating the wakelock with better battery stats or wakelock detector since there isn't access to kernel wakelocks in either of the apps for our phone. A restart always fixes things though, so I have a tasker script now that lets me know when idle battery drain exceeds a threshold for too long so I know to do a restart, it's not elegant, but my battery life is exponentially better and gives me enough battery life to make it through the day without a recharge and leave the eink screen on all night as a tv remote.
I got a new phone

In the end, I got a new phone after my Yotaphone decided to brick itself. Its a Zopo Speed 7, Octacore, dual SIM, nice screen, and does 4G very well in my part of the world. It is also around $200 at time of writing. Its a Chinese phone typical of the genre, Zopo seem to be moderately responsive to bugs compared with Yota... This Zopa phone is running 5.1 Android and I can tell you that Lollipop is not the problem...
That's after charging the phone and leaving it overnight, with the battery saver mode on... not too shabby. Of course it won't actually last 28 days, but this phone is nothing special and it is capable of running without all those services running that the Yota has.
The Yota spent its entire time when I had it trying to contact Moscow with that dodgy 'dictionary app'. What (honestly) is the point of the e-ink display if it doesn't save power...
If you are experiencing "always awake" and wifi always on despite your settings saying otherwise it may be worth going into your advanced wifi settings and changing "wifi frequency band" from "auto" to "2.4 GHz only. I remember reading this tip somewhere else for an Android 5.0 phone that was having battery issues similar to this. I made this change about 24 hours ago and have noticed a dramatic difference in battery drain when the screen is off. When I look at my battery stats I am no longer seeing a solid bar for both wifi and awake. Worth trying.
For what it's worth, I have had fairly light use today, some checking of emails and facebook, 40 mins or so of music via bluetooth (with screen off). Total screen on time of 35 mins. The phone has been off charge since 06:30 this morning. It is now 17:00 and is showing battery of 71% with an estimated 2d and 8h left. Better battery stats show deep sleep of 71% whereas previously it had shown awake at 100%. Far better than I had before.

Have you tried using the setting so Wifi is only on while screen is on? (Unless on charge...)
I think I found the issue, at least with my phone.
I was syncing with exchange, and there is a nasty bug with android 5.0 and exchange sync. The sync is taking forever and doesn´t sync everything. Calendar and contacts missing.
Then I removed the ActiveSync connection on my phone and set up the app Nine to sync instead.
After that I got much better battery. This may help for others as well. The phone is just hammering the exchange server all the time and this takes up a lot of power.
