battery woes :(

ok guys as advised by someone i fully drain my vodafone magic till it dies and then charge it to a 100%.
last night i did the same just before goin to sleep,when i woke up in the morning the battery was at 76% after about 8 hours.I just had 1 missed call,1 sms,1 tweet and 1 email.
How can the battery drain so fast for no work at all???
pls help......

Do you have alot of widgets running? What do you have switched on, Bluetooth,GPS,WiFi? How often do you have the "Data Synch" set for? All of these drain the battery, if they are all working at the same time it goes pretty quick.

Woa! For the battery to drain overnight to 76% is crazy. never had this problem with my magic. It actually last very long.
But 76% overnight most likely means your battery is faulty and or you are leaving gps,wifi,and have quite a few things running on the phone like ClintonH stated.
however if you have everything off, as well as the brightness set low. Then contact Vodafone and let them know your issue. they should replace your battery at a free cost.

I suggest people use their battery for a week or 2 to see better results with their battery life. I started having poor battery life with my magic but now I can last about 2 day before I recharge it again.
As other user mentioned, it also depend what you have on or running in the background when your phone is on standby. I suggest you use task manager applications to kill unnecessary applications that might be running.

thanks guys
nope i have gps bluetooth and wifi turned off
i turned the background data off from settings
will try gettin task manager and see if it makes a diff!
thanks once again

Yes, are you by any chance downloading apps? Sometimes they hang and the download stops / continues lots of times. And when they complete your trackball flashes white.

ok thank mate i'll keep note of that!

I read a quite interesting post in the vodafone forum.
A user complained about the battery life of his HTC Magic. Check the answer from Wayne_Vodafone:
The HTC Magic employs a battery that requires overcharging and topup charging. You must charge it as much and as often as possible. The more you charge the better the battery life becomes. So after a few charges you should see the benefit of this. Letting the charge drain out undoes this so try and charge as often as possible

It actually seems to work. At least for me, try it for yourself.

I have to charge my HT-03A every night if I do not want it to die the next day. I am assuming that is why HTC gives you two batteries, because the battery goes so fast. As long as you are able to carry that second battery around with you, and be able to charge it every night, I don't really see a problem. But for it to go from 100% to 76% overnight means you are running programs that you do not need to. I will add that I have Wi-Fi continuously on, and my Contacts and Calendar are continuously synchronized. With barely any use I am usually at around 50% by the end of the day.

Pretty interesting, and that was an official vodafone response? Why wouldn't HTC say that in the first place? Will give it a go anyway...

Yeah, was a official Vodafone Response.
For me: I've loaded mine over night this morning, now its 19:26 and it's still over 85%. I used it for some SMS, receive a MMS and some WLAN.

ok guys thank u so much for the responses,im gonna give it a go too!
im using taskiller and defi my battery life has improved cause i keep killin the apps im not using
about the flashing trackball.......it still happens...no notifications.....

You never want to drain a Lithium-Ion battery. NiCd batteries have memory, in which it's better to drain them. But not Li-Ion. They will die quicker if you do

ok thanks xantonin.....
i charged my phone to 100%,then made a call for 41 min,battery went to 91%.
went to sleep immediately after that,woke up in morning with 1 missed call and 1 sms,after 8 hours......battery at 70%......thats not right is it?

That could be right.
Depends on what's running.
Where are you checking for 100%?
If you are charging until the green light comes on - that's 90%. The phone takes longer to charge passed 90% than it does to charge up to 90%.
I charged to 99%, and drove around with the GPS on for a few hours (about 2) and came back at about 75%.
However some days, when I charge my phone over night (true 100%), I can listen to music on my way to work (40 mins) on my phone, play with it a bit at work, and 3 hours later it will say 94%.
So, the battery is very touchy it seems...
Try turning off 3G (It's still pretty fast on 2G, try it for a day)
And also make sure GPS is off. Keep your brightness no more than 30%, and make sure WiFi is off. Make sure you don't have any widgets that connect online either.
You should get good standby time

Use apndroid to save battery life
Download apndroid from the Market. Use it to turn off the cellular internet before you go to bed and whenever else you want to save battery life.

There's also an app called Spare Parts in the Market that could help you. As well as giving information about your battery status and battery health, you can also see stastics of your application usage and battery history. A very useful app!
Plus it also enables other features like enabling fancy animations for the keyboard and screen rotation.

If you longpress the red phone button you can also enable "airplane mode" disabling any radio. Which helps your battery life too.

Sigh. My Evo's Battery Life is Rediculous (not typical)

Fully charged my phone night before last and went to work in the morning (9am). I didn't touch it all day, didn't even turn it on. On my drive home at 5pm it was dead, off.
I plugged it in with the phone off when I got home and saw that it was fully charged a few hours later around 10pm and I booted it up and left it alone. This morning it was dead, off.
Looking at the apps that take up my battery doesn't work because it doesn't retain information what happened to the phone prior to the last reboot. Not sure what to do. My awake time matches my standby time exactly. It's obviously a 100% awake time problem but what's triggering this?
I'm on Fresh .3 with absolutely no other mods. I don't think I have any apps that ping outside servers. So what the ****!?
EDIT:
lulz, I just realized I haven't been even able to use the phone in 3 days due to this issue

Something is eating your battery obviously.
Restore to stock and see if you have the same issues.

That's a PITA. This is a clean fresh .3 rom install with only logmein, dropbox and couple non-online games installed. Why is this phone such ****ing fail right now.

Have you removed the Favorites widget? Doing that stopped all battery drain problems for me. Just delete the widget.

First thing to check is if you have a sufficient cellular signal. If you are getting a weak signal it will cause poor battery life. If cell signal strength is not your problem then it is definitely something you have installed on it eating away at your battery. That said check/do the following:
1) Check how frequently you have your accounts syncing
2) Before the phone dies look in your battery use to see what's eating your battery
3) Install a task manager/killer (I use Advanced Task Killer)
4) You don't have to do this one but it does help. I use a program called Startup Auditor to disable startup on apps I don't need to run when the phone first boots (you'd be surprised how many are in there).

delete it completely or remove it from one of the home panels?

the "time without signal" workarounds seem to prove the most effective for me. in addition, reduce background usage and automatic update frequencies as best as you can.
according to this thread [http://forum.xda-developers.com/showthread.php?t=709768] (and link within), HTC has acknowledged some issues and is preparing to deploy a few fixes.

You are running someone else's ROM, there could be a problem with the radio, or a problem with the way it was loaded.
If you are in an area where you don't get signal, you are going to drain the battery, and FAST.
Do you have 4g on but not in a 4g area?

I am...
fully rooted and have fresh .3 as well. I am getting over 30hrs with moderate use and the last hour of that I had everything on to purposely run it down to dead. (was doing a toastch recommeded battery meter calibration).
Took my phone off the charger last night at 7:30 pm. It's 2:23pm and I have 31% left. I have Wifi, BT, and Background apps with auto sync turned on.
I would say you might be experiencing the Motorola cell tower problem. HTC has confirmed that the EVO is not playing well with cell towers that have motorola transmitters. It is causing the phone to use more energy to dial in the tower.
To be sure...
1. Set all apps and widgets to manual update or update once a day.
2. Get rid of the people app or widget from any home screen.
3. Go into Gtalk and uncheck auto sign in. Then sign out when you exit the program.
4. charge the phone until the green light comes on. Don't use a battery meter. The second the green light comes on, go into recovery and wipe the battery stats. Reboot the phone and run it until the battery dies and will not longer power the phone. This does nothing for the battery but does recalibrate the internal battery meter.
5. For maximum life...turn off: background data, WiFi, BT, and Mobile networks when not using. keep screen at 1/2 brightness.
If I do the above and manually update mail, weather, social apps, etc... and only turn radios on when I need them, I can get 40 hrs. out of my EVO and this is under moderate to high moderate use.
One other thing....plug your phone in for 10 minutes. Then unplug it and go into immediate stand by for like 30 minutes. Go to settings>about phone>battery>battery use>cell standby. Time without signal should be very low....anything over 10-15% and I'd suspect that if you did everything in 1-5, you have a towers issue robbing your battery.

I was having awake time issues with Fresh .3, so I switched to DamageControl, and everything has been great. Unplugged this morning at 7, and I still have 75% battery remaining. Better battery life than the Hero or BlackBerry Tour!

I seem to be having the same problem as you and it is quite frustrating. I get a steady 10% battery drain every hour even when its idle. I tried juice defender and setcpu and it is still the same. I turned off all my sync accounts and nothing. I also have systempanel and it doesn't seem like theres a rogue app eating my batteries.I'm going to truth to stock tonight to see if something is wrong with my phone. Did you ever figure out what was wrong with your phone?

AVA9 i get 20 hours a charge
but YES something is eating your battery install system pan have and let it run a bit and check the info id bet its
1 your evo spend a lot of tWOS
2 you have a rogue app eating your battery

Way to bump an ancient thread.

DOH dear god i did not look at that lol

I do apologize for bumping such an old thread, but I feel like this thread has already asked much of what I also wanted to ask but have not reached a conclusion. Therefore I would like to try and solve the problem or provide as much info as I can to solve the problem.
I indeed have installed systempanel and here are the screenshots for the day.

As you can see besides the internet, there is nothing else thats taking up the battery. Also I took this pic after I put the phone on the charger for a bit, it was at ~ 13% before. The battery usage information says a majority of the battery was used by #1 android system and #2 cell standby, it was neck and neck almost, with #3 being phone idle. My weather app polls every 3 hours, my facebook syncs every 30 mins, my htc sense facebook syncs once a day, and I have not configured any other emails except for two gmail acconts, which received probably 3 emails throughout the whole day.
I just used setcpu today, it made absolutely no difference. Same results as yesterday when I did not have setcpu. Thanks in advance for the help!

dude you need to try my setup: superevo and setcpu
i got 7 days of battery using the evo as a simple phone.

Why would anyone use an EVO as a simple phone.
I am beginning to think peoples opinions on moderate use vary tooooo much. The EVO is similar to an unplugged laptop. The more you make the cpu work the faster your battery is going to drain.
It seems some people just dont get that.

Answers on battery life.

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.

Use APNDroid. Comes with a widget.

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..

My experience with GREAT Galaxy S battery life!

Hello Everyone!
I made this thread hoping I can shed some light to those getting very poor battery life. I was also getting very poor battery life, till I went and exchanged my phone for a new one. If you're getting very poor battery life (even after wiping your phone or installing a clean firmware), there is definitely something wrong with your phone or your battery.
I own a i9000m bought from Wireless Wave. I've unlocked the phone and am now using it on Rogers.
My previous phone, I was draining 25% of my battery to just get through 6 hours of standby while I slept. I had juice defender on and autokiller memory optimizer. I turned off all syncing and didn't even use a live wallpaper. My phone was rooted and also had lagfix (which I soon removed). One thing I do remember doing is not charging to 100% when I first got the phone. I did accidentally let it drain to 0% cause I had to use it right away.
After exchanging for a new phone and charging it to 100% right away, I was getting the following results. I have juice defender and nothing else. I changed my band to be WCDMA only. I even have a live wallpaper on. Last night my phone idled for 9 hours and it only drained 2%! Last night going out, I had a moderate to heavy (fbook, 3g, gps, text, youtube) usage pattern on my phone and it only drained 40% after 6 hours of use.
I don't know what else to say, but I'm letting those with battery problems know that the SGS is capable of great battery life. And if all your optimizing and tweaks aren't doing it, then you may want to consider exchanging for a new phone if you still have warranty.

I have a great battery life too in my device compared too the another smartphone i used in the past and now compared to Ip4 and N8 in this devices the bat drain is much higher. So im positive surprised with
the galaxy battery performance, i only use the push email everything else is turned off, livewallpaper and so on..

My phone came with JM7 firmware. My battery life is just excellent, not needing a recharge before a few days with my use

Running JPM here, with darkyy's raw metal ROM, my battery life went up by at least 40% - %50. I was losing 1% per 5 - 10minutes of usage, now its more upwards of half an hour of usage.

I think the phone has very good battery life if you understand what can cause battery drain and adjust it accordingly.
I am now gettining 5% drain per 24 hours on (almost) standby. This would give me about 20 days of standby which is crazy.
Here is my setup:
UK 16 Gb Galaxy S with Eclair JM6 and Voodoo lagfix
Set network to GSM (2g)
Disable internet usage (with APNDroid)
Disable WIFI, Sync Off, GPS Off (with power widgets)
Just before I go to bed, I run Advanced Task Killer and kill anything that doesn't need to be on memory (inlcuding Advanced Task Killer itself).
Using your phone WILL spend a lot of battery. Browsing the internet on 3g is a battery killer. This means that if you do something on your phone that maintains an active 3g connection, it WILL drain your battery in about 3-6 depending on your 3g coverage.
WIFI is better, but again you are looking at something between 6-12 hours of continuous usage, so make sure you only use it when you need it.
Finally, if you need to have your emails the instance they arrive, go for a blackberry because it has the only way of pushing email without maintaining a constant data connection.
I don't need this so I am extremely happy with my phone and the battery life I can get out of it.
I hope this helps.

Have my phone set for 2G with wifi always on.
Use wifi at home.
2G is enough for all normal syncs, and if I need more speed for anything else I temporarily switch to 3G for that.
This way a single charge last me well over 24h under normal usage. Don't even know exactly how much.
With the phone set to 3G, the same usage patern will eat a full charge in something like 8h.

JPM Rom with everything except bluetooth turned on my battery lasted 3 days with low usage (skype a few times and some phone calls and a bit of wifi web-browsing.)
Much better than my wife's iPhone 4... Normally charge it every 2 days.
I am very happy with the phone, just a couple of bug fixes and I would really like it if Swype did some level of contextual checking of words to help minimise unnecessary corrections (perhaps they do already, but it is certainly not well implemented/sophisticated enough).

Which ROM was on your old SGS and which one is on the replacement?

Eclair for both. No Froyo.

what i wish to have is greater control over the phone, more easily.
Some kind of powertop GUI that let you see the power usage per process.
So you could plain uninstall apps installing ****ty services consuming the battery.
Likewise i'd like *real* control over which background services are running. I mean running an auto killer wtf? Horrible design!
I just want to switch off a service and that it doesnt start again 5 min later thank you very much.
Even the task manager is quite bad. You see last started apps but you don't know which one is running right now. And if its running and backgrounded since a while and you started other apps.. it might very well not even show up in the list anymore. Horrible design again.
Saying all that because stock the phone battery is excellent, installing a couple of popular apps kills it..

Thanks for your prompt reply. Could you check it more precisely on your current SGS? FYI: Settings -> About phone -> Baseband version and Build number or "call" *#1234# -> PDA, PHONE, CSC version numbers. Thanks in advance.

Sure thing. And thanks. KIES offered an update from JM1 baseband and JM2 build version. We'll see how the new ROM performs in about 3 days. Unfortunately don't have spare time to do that sooner. I suspect there's huge difference within the baseband versions.

hey guys.
i have galaxy s i9000..i also had problem of battery.my battery would hardly last 24hrs...i even switched to gsm only mode n switched off sync.but still had same prob..few days back i installed JPJPA firmware..now its wroking fine.lasts more than 35hrs...n also battery charges quickly

Is it possible that the reading on the phone is wrong? When you say you are getting 24 hours are you letting it run flat.
Alternately is it saying the battery is running low and you recharge before it goes flat?
Just wondering if the meter is simply giving incorrect information.

Been 24 hours since last recharge. Lost 6% so far. Running JP6 Froyo. Rooted. Network Data Off. During this 24 hours, just used Angry birds-30mins and ColorDict 5mins. Haven't installed any unnecessary app.
Had lost 1% on standby after 14hrs with no usage. Thats amazing. Very Happy user.

Also want to tell u guys that GPS with active Data connection and Google Maps running and display on took approx 1% of battery every 3mins.

Impossible using stock battery, this phone draws a minimum of 10% battery per hour the screen is on. Its more likely 15-20% with most peoples phone.
Your battery meter may be inaccurate, for example after flashing once my battery stayed at 100% for hours then suddenly shot down to 20%

I use "Battery Indicator" to check my battery status.
My screen is set to turn off and lock after 30 seconds of idling. So it is quite possible to achieve the standby times listed.

Hi, how long do you have holding time of battery, when you are using wi-fi? (browsing)

[Q] Unrooted Note 3 - Battery Drain, Most Tips didn't work.

Hi Guys,
Firstly, I know there are several threads with different tips and suggestions but most of them didn't work for me.
Recently (since more than a week) , I have noticed strange drain in battery and getting hot pretty quickly. It has kitkat and I didn't get time to use it properly in the beginning. After reading different threads and forums here's what I did:
- Let it drain completely, shut off, took out battery for a couple of hrs and then charged without switching on. x2
- Rebooted after charging
- Uninstalled some apps I thought might be problematic
- Factory Reset (such a pain!)
- When attached to Kies, it prompted for Firmware update N9005XXUENC2 followed by another factory reset and hard reset.
- Cleared cache by going into recovery mode.
- Rebooting after charging
But seems like none of it made much difference, my routine use
- couple of hours on wifi
- no heavy games, only temple run, subway surf etc.
- no streaming
- no lengthy calls, not a lot of messaging
- 1, 2 hrs of music
- Syncing off, gps off, blue tooth off, Wifi mostly off, power saving on, brightness on auto, no 3g/4g data, almost no photos and video capturing, sensors, motions off except smart stay
I don't want to root the phone because of my busy schedule, with some difficulty I was able install WLD on it which resets after Rebooting. Point is, I am not a heavy user and this being a "beast" isn't quite unleashing the beasty-battery-life. I do get more than a day but that is when it's in deep sleep for 20hrs or more. I took some screenshots after reseting, updating firmware. It's past 3 battery cycles now, I will attach the latest one's to not clutter it up. I like this phone, but this battery is just not good enough. So, please helpful answers that don't require rooting.
Thank you for reading and Good day!

Is the battery drain consistant or does it happen at certain times (at home, at work, etc.)? If you are in an area where the signal changes frequently that will drain the battery because the radio is using power to maintain a connection. With wifi scanning for google services even when turned off setting make sure it is off if you dont need it. How do you charge the phone? If possible always use the charger that came with the phone, charging from a usb port from a computer is not as strong and can affect the memory of the battery and do not wait till almost dead to charge. It works best to recharge when between 35% and 45%. Look at your background services and see if anything out of the ordinary is running. And it could be possible the battery is defective and you might want to have it tested. I use my Note3 lightly and get 24 to 25 hours over two to three days (turning off at bedtime). This may not help any but this is what I have learned from others with similar situations. Good luck!

Hey MPDnnrd,
Thank you for your response.
It is sort of consistent, did you see the screen is just at 18% and the Android system at 30%? I think this is where the core problem lies - just don't know what and how to fix it.
- Signal Strength: Pretty good, hasn't been a problem
- I normally keep the wifi-scanning off and Now I turned off the location services to see the impact but then I think what's the point of premium device if you have to switch off everything.
- I prefer to use the factory-charger over usb-charging and I read it on several threads to let it completely die and then recharge, guess that didn't help.
- Background services - I don't think so, I kill all the apps as soon as I stop using them, use Greenify to hibernate other, switched off all auto-updates and notifications. Even on Playstore, I switched off the auto-updates and notifications.
- Defective Battery: Now this one, I haven't tested yet not sure how to - the phone's just 2 months old so shouldn't it be good enough?
I know they are not very helpful, but still thank you very much. :good:

I'm sorry to have to say this but I think you got a pretty normal battery drain by looking on your screens. You played almost one hour subway surf(which drains the battery pretty quick) and I guess the other hours where internet (also known to drain battery) or calls/messages. On a not rooted device with stock kernel that seems like normal battery usage to me!!!
However if you like to check these maybe u get a couple of percentages(not that much though I guess):
-Power saving mode in notification drawer makes your cpu clock go down (not sure u got it on not rooted device sry)
-check turn of pen detection in s pen settings
-put the brightness on auto or put it down manually
-if you can change the theme color in apps do so(make it black)
-check the svoice settings so it doesn't listen to your voice
-if you don't care how your phone looks buy a zerolemon battery(I think it makes your phone too big but that's preference)
-don't use a bright background keep it dark colors and no live wallpaper as well
Maybe that helps a little.

I don't see any drain either. Almost 6 hours screen on during 24 hours is excellent, additional 1.5 hour awake time for other services. Excellent battery life.

Settings - General - Applications - disable unnecessary apps
In Google Settings, opt-out interest-based ads and disable location access.

Thank you for your reponses guys - thing is it actually had much better battery life. What I don't understand is the fact that Screen % used to be on top and android os and system was below it but now it has been on top.
I have tweaked quite a few things already that 4aces suggested and the S-voice thing seems new, I'll look at it. Today it didn't even last a full day whereas I know people who even after heavy usage get easily more than a day - mine one, I don't use it this much. The Zerolemon thing is beast but then the phone is a freakin block lol so heavy and big, good travel etc. where you can't charge your phone and has a rugged case.
But there's a change that I saw today, Android System is now below the screen so I am not sure what made it do that but may the next time I charge it gets better and so on. I'll keep you guys posted after charging it today, I'll monitor what I do.
Blondasisko - I wouldn't really call it excellent, but it's sort of getting better than it was in the first 2 cycles. But how do I reduce additional awake time for other services? Moreover, you might've noticed I got till 1% to get this much time like really stretched it to get there.
Someguyfromhell - Already done, locations were off starting today.
Can anyone else comment on their daily routine of usage and the battery drainage ratio?

If I get 12 hours and 4hrs screen time I'm happy. I don't even play any games. Have a lot of accounts syncing lot of Internet and a bit on the calls, gps. I get on average 14 -16 hours
I have brightness on high. If you put it on auto it makes a big difference.

I guess I should feel lucky, I have ZERO syncing, auto brightness, no live wallpapers or gimmicky stuff on, no gps, hardly 10mins or so on phone calls and prolly 30-60mins on messaging a day.
@all others - and the Android System is back on top - what could be the possible reasons for it?

I think its because of such minimal use that the system goes on top. The system still had to operate so when you have hardly used the phone then the system will go on top. Though with that usage you've stated you should get nearer 2 days really

You're right probably, this is what I'd like to know as to what is running in the background that drains more battery? Exactly, at-least 1.5 days is what I should get with this usage. May be I should buy a new battery and see how it works.
