Battery life sucks

I've had my battery replaced, I've wiped my phone from ROMs, and I've used aggressive SetCPU profiles...
What is annoying though is setCPU recently updated and I decided to see how my phone ran without it.. battery life is horrific with a simple UV kernel.. Why is this?
I mean I take my phone off the charger at 11am and by 10pm its less than 15% remaining. I now have a second battery from HTC after a warranty replacement but I saw very little change. I have a task manager that auto kills everything now which helps but it is annoying since I lost my car charger my phone is discharging all day.
Is this normal and I'm just freaking out or do I have a real problem?
Running Kang-o-rama ROM with ~20 apps

I know 3 things about the N1 battery:
1) it took a couple of weeks for my battery life to max. Lithium batteries need a break-in period. They have no memory, and the recommended approach of not using the phone until it's full charged is bunk. Just use it normally and it will work as it should.
2) Switching between 2G and 3G constantly murders the battery, 4 hours and you're dead. If you're going to be in an area like that for a while, force it to one or the other.
3) Watch your apps. If your phone is acting even slightly sluggish it's CPU is maxed which is killing your battery. Slowly swipe between homescreen pages, it should be silky smooth without any stutter. Try and track down which one it is and either install/reinstall (which fixed an issue with Better Keyboard for me) or completely uninstall if you can't fix it. Check for apps that ping the network too often, or ones that start up on their own.
I will add that the built-in 2.1 battery usage tracker is not 100% accurate. In my Better Keyboard example, Android said it was the screen using all the juice, not the app. Might have to do with video graphics drivers, I really don't know. Point is, after uninstall/reinstall my screen used 55% of my battery instead of 75%, so don't trust it.

Are you kidding? You're running your N1 for nearly 12hours and you STILL have 15% juice left?!?
Search the forums, 12hrs and still having juice left would be considered excellent to many.
...Then again, you haven't mentioned what your usage is like. If we were talking about your phone being in sleep mode for most of those 12hrs with just an occasional call or 2 that only lasted very briefly...Then that's a different story.

Have a look at Juicedefender, it will limit your internet access to 1Min on every 15Mins when the phone is asleep/screen is off. Does wonders for battery life

[Q] Tips to extend battery life? Anyone?

Hey guys,
Just got my Epic yesterday.. coming from the G1 with lots of experience loading and tweaking ROMs and dealing with same/similar battery issues.
After unpacking the Epic I used it and let it drain down to zero before recharging it; after a full recharge, I loaded up the 7 screens with widgets and ran a live wallpaper (fish). I didn't really use the phone much at all and the phone went from 100% battery down to zero in the span of only four hours!!! Geeze, you've got to be kidding me - four hours battery life?? WTF????!!
Back to the drawing board: I rooted it and ran SetCPU with some power saving profiles. Removed the live wallpaper and went to stock wallpaper. Set display power off at 30 seconds. Note that 4G remains off since there's no 4G in my area..
Couple of questions:
1. Is there any way to toggle 2G/3G like there was on my old G1? I know that was a power saver.
2. I didn't stop to read all the documentation yet (typical male, I know) but is there any way to wake this thing up from sleep mode besides pressing the power button? I can see that power button breaking for as much use as it's getting from me constantly having to wake this thing up!
3. My brightness setting is set to auto - since the display is usually the biggest drain on these things, is there a recommended manual brightness setting (percentage) that seems to work well for you and saves on battery power?
I'm waiting for the Seideo Extended Battery (just like many of you) and am wondering if I should keep the Epic since I'm on the Sprint 30-day Easy Return program.
Appreciate hearing from everyone!

I don't have 4G where I am. But, I have a all black wallpaper(uses less power) and unrooted. I easily get about 12-18hr out of my phone wit normal use(text, talk, and surfing the net with skyfire). Only thing that really kills my battery are games(Robo Defense can take over 30min to play one game).

Thanks for the reply - situation NOT improving
Thanks for the reply.. unfortunately, the situation is not improving...
I tried setting a Sleep Profile using SetCPU that would under-clock the CPU (using the stock kernel) once the screen dimmed and the phone went into Sleep Mode. Unfortunately, as mentioned in another thread here, the result was that the phone froze and required a battery-pull to reset.
I'm really starting to lose my enthusiasm for this device; as beautiful a display and as responsive a CPU/GPU, all of that doesn't mean much if you don't have good power management built into the firmware. At 6PM this evening I pulled it off the charger at 67% charged, it's now 8:35 PM, only 2.5 hours later and I'm down to 22%. I'm in a decent coverage area and get 2-4 bars of 3G strength so I don't think it's an issue of the radio being the culprit; in-fact if you check the battery stats it reports that that lovely Display is accountable for 78% of the battery usage! So I guess we're paying a hefty price for these 4-inch AMOLED displays!
I read somewhere else that the most recent update (DI07) has caused the battery performance to decrease; since my unit is brand-new it immediately went and installed DI07 shortly after the first boot-up so I have nothing to compare it to.. can anyone comment on that?
Thanks!
Chris R.

I'm sure custom ROMs will put performance / battery life on the top of the list but until then, I use JuiceDefender beta and have seen pretty good results with it. It shuts off data whenever the screen is off and since my screen is off a good amount (only use my phone if I need to check email, call, and / or text, which is rare when I'm at work). Other than that, yes, use black wallpaper, lower brightness to the min. in the OS and browser, and don't leave apps that constantly use 3G open (things like ebuddy, pandora, etc.). 3G really destroys battery life so minimal use of 3G data would maximize battery life. Maybe the devs can figure out a way to get at least one full day of battery life on this phone. I'm hoping that is the case.
As to your post, yes, DI07 has resulted in poorer battery life, for whatever reason. I was definitely getting a few hours more with the older firmware. I would not lose hope yet. As disappointed as you are (and all of us are, I can assure you of that), the devs are really starting to push out nice ROMs already, and in a few weeks to a month, I bet we will see some solid battery life. Hell, even 2.2 should yield much better results. Patience

Thanks for the tip!

DI07 has hurt my battery life substantially. In fact, my battery drains very close to twice as fast now with the update. I don't understand what they did. My phone certainly doesn't seem any faster, my display is dimmer, and battery life sucks. I'm going to have to go back to DG27 so I can use my phone all day. With DI07 it always dies on me by mid afternoon. With DG27 it was still running by 11pm at night without even a battery low warning.

juice defender ftw
also, use advanced task killer with low security settings to kill all the background processes. Set the autokill to when the screen turns off. This keeps everything pretty well managed and helps with battery as well

JUICE DEFENDER BATTERY!!! Saved my phone from flying out of my car window at 10 in the morning........

here is a link to a thread I started.
Sharing my juice defender settings. I also use ultimate juice.
http://forum.ppcgeeks.com/sprint-epic-4g/133933-sharing-my-juice-defender-settings.html
I can get a day and a half (or slightly longer) out of a single charge.
YMMV.
Hope this helps

Advanced task killer + Juice Defender. You could also get some custom roms and Kernals that would help boost it.
But that's your best hope. Keep off 4g, wifi, bluetooth, etc.

Ah, the evils of DRM can strike in unexpected ways...
I wasn't really having a battery problem but I just turned DRM off, so we'll see if battery life improves anyway.
I had a whole long post here that got wiped with the xda disk array failure, so I'll just sum that up here too:
1) Use wi-fi if possible - it REALLY helps
2) 4G does not seem to use the battery any more than 3G, although hunting for 4G does and 4G coverage is not as extensive as 3G even in 4G areas. So it's still best to leave it off if you're moving around.
3) Dim your screen and use a dark, static background. AMOLED screens don't work like LCD's; they use more power the more pixels are lit and the brighter they are.
4) GPS also kills your battery - leave that off unless you need it too.
I think that's it. I get about 18 hours on DI07 (even before trying the DRM thing; maybe I can get to a full day!).
One thing I'm noticing after checking DRM - I've got Google Maps' LocationService popping up about every 10 seconds, and I can't seem to shut it off permanently. (I went into Lattitude and turned that off, not sure what else to do.) That can't be helping... anyone know how to get rid of that?

I'm using juice defender and a constant email junkie, but lite use on other aspects of the phone. It goes off charger at 5:30 am and I'm about 67% at around 3p. It then goes in the car charger on the way home. This has much better battery life than the Pre or the Hero as with both I had to turn off email to get it to last throughout the day.
I don't expect these phones to last days, but I expect any phone that I get to last the business day. I've always been one to charge overnight.

Wifi drains battery more from what I've read.

I've heard the opposite that wifi (as long as it's connected) uses up less battery than 3g/4g. Any of them will suck the battery dry if they're searching, so make sure you have a connection to one of them.

Hi everyone, new to the forum. Just started checking it out when the Epic was released and this is my first post. Anyways, here's my question. My phone's been off the charger for 7 hours and 17 minutes and it is now down to 15%.
Display 79%
Cell standby 7%
Android System 4%
Phone idle 2%
Swype 2%
I've gone into the display settings and I thought I had set everything up optimally. The brightness is always very low. The screen timeout is 15 seconds and the keyboard matches that. I don't know what else I can do to cripple the phone to get the battery to last longer.
I have had wifi on, 4g off, bluetooth off, gps off. Really all I have done this afternoon while watching NFL games is check my yahoo fantasy score, play 2 games of WordFeud, and check twitter and facebook. I purchased Juice Defender a week ago and it has been running all day.
Any suggestions for how I can reduce the drain from the display? My background is a black and white picture of a friend of mine, which I thought would help.
Don't get me wrong, I love this phone. But the battery life I've seen is just terrible. I'd love to buy the extended battery from Seidio whenever its available, at least that would make it last longer even if the settings aren't tweaked.

Do you have juice defender installed?

Yep. Its installed and running now.

There are only two reasons for your display to be using that much battery:
a) it's too bright, or
b) you're using it a lot.
If you're using the phone a lot, your battery's going to run out pretty quick and there's no way around that. If you're using it a "normal" amount, which to me means maybe an hour *total* per day of having the display on, then the other culprit is going to be your brightness. (Some would argue that's less than a normal amount, but think about it... you get a new phone, you're going to play with it for a week or two until you've seen all the cool stuff. But at some point you're going to start putting it away most of the time and just using it when someone calls you, you get a message/email or maybe to play a game or two while waiting for the train.)
Set your brightness *all* the way down, just as a test for a couple days. Make sure all the "power saving" features of the display are turned *off* (auto brightness, and whatever that "picture detection" feature's called, I can't remember). You just want the display as dim as possible all the time, just to see what happens. See what the battery usage says after a day or two of this.
My bet is that you'll see a drop, and then as you get into a more normal usage pattern it'll drop further still. You can raise the brightness a couple ticks then as you learn how to stretch your battery out.
Personally, my display is rarely over 15% or so of my usage. Today it's 29%, but it's a Sunday and I don't have anything better to do but play around on my phone.
btw, it's still the first day I've tried this but that DRM thing might be working. It's almost 9PM and I'm still on like 80% battery, and like I said I have been using the phone off and on throughout the day.

That has helped tremendously. I installed it pretty much when I got the phone and I'm able to last the whole work day with 67% left. (10 hour day)

Juice Defender With Ultimate Juice Benchmark!

Hey guys im in the process of doing a little experiment to see actually how much Juice Defender with Ultimate Juice actually improves the battery life on my Evo4G. I'm sure this has been done somewhere else i just couldn't find it so i decided to do the experiment myself and post my findings this may be useful to some people or may not!
Phone: Evo 4G
ROM: Cyanogen Mod 6.1.2
Kernal: Zendroid BFS @ 1.52ghz w/ smartass scaling
Launcher: Go Launcher
-----------------------------------------------------------------------------
Phone running Juice Defender With Ultimate Juice
Phone Unplugged At 11:42am
Phone Died At 8:59pm
Usage: For the most part it was moderate use, no gaming, 2 calls lasting for a total of aproximatly 45 minutes. 120 texts were sent and received 146 within the time frame. There was no browser usage just mostly texting like i said. 3 Pictures were taken. No Wifi. Bluetooth or 4G used either.
-----------------------------------------------------------------------------
Phone running without Juice Defender With Ultimate Juice
Phone Unplugged At: 2:50pm
Phone Died At: Never
Usage: Well my phone has been unplugged since 2:50pm and its now 12:35am and my battery is sitting at 55%. Weird... very weird. I had about the same usage as yesterday i played 1 game for a total of probably 10minutes and installed 4 apps. A had wifi enabled for probably an hour total.
-----------------------------------------------------------------------------
Final Thought: I think Juice Defender doesnt help at all, infact it seems to hurt your battery more than anything. I think it may be because its constantly turning things off and back on consuming battery? Thats the only thing i can think of. Does anyone else have any thoughts on why this is? Using Juice Defender reduced my battery life dramatically it almost cut its life in half as a matter of fact. Please share your thoughts on why this is people!

thanks for the info. i try to tell people that juice defender doesn't help. but no one listens so i gave up and just tell them cool app and walk away lol.

very helpful post. I noticed too it doesnt seem to really help it just monitors mobile data and turns it off when screen is off and occasionally powers it on to download emails and ****. I dont like it because i like to kno when i get an email instantly versus it checking every 30 min.

I also found that juice defender seemed to have a negligible impact on my battery life while also decreasing speed of sync/convenience. You'll notice that it also makes android system skyrocket towards the top of the battery use list.
On a related note, I also found that setcpu profiles don't have an impact on battery life and may even hurt.
Ultimately, android is optimized to manage a lot of these things on its own and introducing an app that consumes battery both monitoring and brute forcing some of these activities doesn't make sense. The only active monitoring app I use now is Tasker for some specialized automation activities.

i cant believe this is an app that most people recommend to improve battery life tho. Especially with how much it hurts rather than helps. Very disappointing.

It has helped mine because I use the widget to manually shut it off and on. I don't let it control it. Since the epic doesn't have the shut off data in the power menu its good for me. Otherwise I agree with you all. I keep my data off until I need it to look something up. Personal preference. But hey it does shut my data off when I tell it to.

I've got 58% left in the battery and the phone has been up for 32 hours. I thought I was helping by micromanaging the phone with JD but I think it was really just hurting it.

32 hours up and only down to 58%? Mind if I ask how you set thigns up that your phone is so energy efficient?

It was a great application, Donut times, it literally made my Magic 32a survive the day against the not-even-a-day battery life at those times. Nowadays it is simply useless due to android better app management.

Hmmm...I have been using this for a few months now and I've seen dramatic improvement in my battery life. I usually unplug my phone at 7 each morning and by noon on moderate usage days I'm at 60%. Using JuiceDefender, my phone is typically at 80%. By 5pm with its only at %60. Normally I would get home at 5 and it would be around 30%. Interesting.
Running Samsung Captivate
Stock Android Eclair 2.1
Rooted
Zeam Launcher

With more iterations of Android they are improving power managment, Ya back a little bit ago this helped some people alittle it closing out processes and way to handle things but with android development alot of this stuff is getting worked into the OS, basically now all your doing is running a app constantley that does something handled by the OS now in newer builds.
I wonder in some cases if the juice defender and the OS both trying to do power management if it can actually cause more power loss due to a conflict in the two trying to controll items. Of course OS should have higher pid but could cause some of your increased power drain using both

try the beta

im using it on my epic and my evo i think it helps both but i am also using the free beta i dont think the regular one works

i'm shocked there's even a thread for this. i put it on a stock epic and it made a WORLD of difference.. especially in locations where my signal was poor and evdo service kept dropping. my issues with it are of a different nature. seems to get corrupt alot and the wifi locations service sucks

Hmm, i'm confused on how this could actually hurt battery life, especially by the amount you displayed unless you have it doing all kinds of other management as well. I have mine setup to only manage the data APN, disabling on screen off, and seem to have gained decent battery life from it. The widget to toggle data on/jd on/off is very handy as well.
Pretty sure android doesn't do anything natively that turns off data when phone is at rest/screen off, does it? Someone please correct me if i'm wrong.
I will admit, the new versions of JD do seem to be pretty bloated and sluggish.. i've been on the fence of whether to remove or not... The main reason i keep it on my device is because i work in a basement and get about 65% TWS and severe battery drain from that. With JD managing 3G, it helps mitigate that somewhat, and having it be automatic is much more convenient than toggling it manually all the time.
I may have to join you on some testing, because if JD is not gaining me anything, i'll definately be removing it as it sometimes causes some initial sluggishness when turning the screen on. From daily usage experiences (and i watch it like a hawk), my battery life has definately not been made worse.. older versions seemed to net me more life, and i'm undecided on the new versions. Not enough time with it on/off to decide yet.

Most Def Work
JD helps... it will slow down notifications and stuff, if you need always on data then this won't help. However, during the day I'm usually already online and don't need non-stop notifications and if you use JuicePlotter you can clearly see that while sitting idle with JuiceDefender on you use significantly less battery than if you don't have JuiceDefender active and have it sitting idle.

for those that think jd works...
are you using the free, pro, or ultimate version? looking to buy if it really saves battery life.

which configs did you use? I had it a few months ago and my battery did actually improve. Trying some different settings makes a huge improvement.
I am using superpower now. (from XDA actually) And this is really working, it also takes some configuration, but eventually it will benefit your battery life.
Superpower turns data to 2g when your screen is off, disables wifi and bluetooth and sets your cpu to a 400mhz cap (at least with my phone) I noticed a 1% overnight drain and a 200% increase in battery life. (basically I do two days with heavy use vs. one day before)
Hope this helps some people!

The only thing that actually changes the battery in an evo is a kernel. No quick fix app is going to help how your system interacts with your battery! Senseui is garbage and it sucks up battery life like no bodies business!

[TIPS] Juice Defender, Why its good and bad

Reading through threads I see lots of people saying JD and similar apps are good and lots saying they are bad. This is quite confusing for someone who just wants to get good battery life. In my experience I have gone from finding it good to finding it bad. I will try and explain why this occurs so that people are able to decide if it will be worthwhile for them.
First install Battery Monitor Widget and find out what sort of drain your battery is experiencing every hour.
With a stock rooted G2 with data connection on continually (no wifi) I was getting around 80-150 mA which explains why it would not last longer that about 16 hours. Most of this drain seems to occur from data connections. After installing JD or something similar the drain can be reduced to around 50 mA. Which is great, suddenly you get the claimed 1.5 to 2x battery life. JD seems great.
But after you install a good ROM and custom kernal, remove or freeze all the apps that keep using your data connection unnecessarily and install Better Battery stats you observe that JD stops the phone going into a proper deep sleep. If you dump it the drain on the phone drops to very low numbers usually under 20mA sometimes 5mA or even 2mA. This means you use around 1-3% of the battery life of the phone overnight with no changes. Now your phone can last days between charges. Note this is with Data or Wifi connections turned on and Sync active always.
Summary:
On a badly set up phone JD improves battery life (for the lazy)
On a well set up phone JD worsens battery life (takes some time)
Note: I got the best results using Speedmods kernal but I have no reason to think that other kernals could not get similarly low battery drains.

Thanks for sharing your observations. I have juice defender and have had similar findings. The wake locks jd causes play into the aos bug of the phone which is why it can make things worse on a well set up phone (the extra drain from the wake locks outweighs the savings from turning the data connection off when it's not in use). If not for the aos bug it would probably be good in all cases. I had noticed this in my testing and am glad to see I'm not the only one.

Thanks for sharing your observations.
If I had seen your post much earlier than I wouldn't have to buy JD. Anyway, I have gone through the hard way, and learnt how to keep my phone organized and minimized rouge apps issue. JD is pretty much useless now.
IMHO, I think Battery monitor widget pro seems to be a much better buy

Thanx for this helpful info!
BTW, kernel not kernal

I do not have a lot of widgets and sync as little as possible. Mail sync is only on demand (when I have time to read it), and Weather is every 6 hour (disabled in night time).
So my battery live is good ½% standby and with normal use it can easily last a full day (no gaming, just Internet, Talk, SMS).
I decided to try JD in order to save even more juice, but JD ended up using more battery than it saved me!
So I can confirm that JD is good for the "lazy user" and bad if your aware of your sync. and how your apps behave.

What do u mean by dumping? You said if you dump it and the drain goea away? Im a bit confused

By 'dump' I just meant uninstall JD. If you uninstall JD your phone will be able to deep sleep properly provided it is set up well and you actually save more battery.

Sure you can do that, but it's not necessary. I leave wifi and 3g on and still have drain of 5mA all night. I wake up and have lost almost no battery. The same applies for when the phone is idle during the day.

Pathetic Battery Life on Vibrant Trigger

SGS Vibrant flashed with Trigger 3.2 the battery lasts for 1 day with wifi usage and even if kept for overnight it drains about 18-20% of battery should i move to a different ROM ?

You could

Trigger has had one of the best all time battery life for me a everytime.
I think you need to
A) recalibrate
B) re-check to see if any apps are using battery life.
C) flash a rom if none of that works.

Here we go again for the millionth time.....

But for me trigger had the best battery life.
I'm not on the gingerbread roms and it takes me from 100% to 5% in 8 hours overnight even WITH Juicedefender (seems to be about the same without it also).
If anyone has tips on THAT, I would much appreciate it. I've tried calibrating the battery.

There is a setting that you can turn your radios of from x time to x time overnight. I have mine set for 11-6. If I am on after 11, then I take priority. If not then the setting does.
There is also a setting that will open data/radio every 15m/30m/45m/1h/2h or something like that to get updates for somethings (i.e. Beautiful Widgets). I have mine set at 2h. If I want my data/radio open I will do it myself, hence my long interval.
Been using this app for well over a year so I know how to tweak it a bunch. If you have JD+ see my battery guide and it will tell you more about its tweakiness.

Trust me. This guy knows how to use JD, check out his battery guide. It will be worth your time.

i wish i could get my phone to last a whole day without charging, i just dont complain because i know for a FACT that the reason my phone only lasts 10-12 hours is because of ME. im too stubborn and refuse to switch to battery-friendly usage. the biggest thing that impacts battery is the user/user apps. not rom, not kernel, the battery difference from rom-to-rom and kernl-to-kernel is barely noticeable (unless in the rare case where there is a bug, or developmental defect). if there was ACTUALLY a rom in exsistence that TRULY had superior battery life, then you wouldnt get 5-10 different answers in every single "what is best rom/kernel for battery" thread.
the problem is, people want to believe that they can save battery without changing their usage habits. this simply is not possible. no rom or kernel will realistically do this for you. if you remove 1 brick from a bag full of 15 bricks, the bag will be lighter, but still very heavy. you need to download "spare parts" or "process monitor" from the market and start analyzing the way your apps are acting. also look into data syncs that are happening in the background. apps that stay open behind your back/what they are doing, (an app called "autostarts" can prevent apps from self-running under certain scenarios). animation speed. polling for notifications. gps. wifi scans. overclocking. cpu/ram usage. proper sleep. widgets. brightness. 2g/3g. data usage. call time. text volume. - THESE are the things that really affect your battery life.
bottom line is, if you truly want to save battery you are going to have to get your hands dirty...there simply isnt a one-click (or one-flash) solution.

Hmm so i'm now on MIUI and it seems to be giving better battery life, also have been thinking of getting the extended battery for Vibrant is it worth ?

If it sucks so bad, grab one of these. I have it and it has given me at least a 20% increase in battery life. BTW, you must listen to the instruction for the Battery if you get it. 4 or 5 full Drains to 0% and then charge to 100% while device is powered off and re-calibrate after each of these full charge cycles.

But the gps doesn't work on it correct?

What about the extended battery which is around 3500Mah

I just got the 1800 mah batteries for the Epic 4g. They fit in the vibrant like a glove and my battery life has been significantly lengthened.
