I've had the SGS2 since it launched on the AT&T network. I've never noticed the battery life to be really horrible but over the last three days it's been draining rather quick. I'm still on 2.3.4 with Baseband version KH7 having rolled back from the update with Odin one-click a week after update due to horrible wifi problems.
I check my battery usage this morning and noticed that the Android OS was u sing 22% of battery. Is this a normal percentage or is it high? I haven't downloaded anything new but did shutdown my phone twice this morning seeing if it would maybe fix the battery problem.
Any feedback would be greatly appreciated. Thank you for your time.

Please search for the answer. This has been asked 100 times (this is 101) and there are multiple threads on this same topic.
okay I did and nothing really answers my question. I get things that talk about 50% and above but there's nothing about lower than that. Mine used to be at 12% and lower. I don't know what would cause it to just jump up for no reason. No reason to just tell someone to search not knowing if they did or not. Thank you.

Well you obviously searched and just answered your own question. But you post gives us almost 0 details. Have you downloaded any new apps? Do you use your phone a lot, this would affect how high it will be. All this has been answered multiple times before

First step is to install BBS and CPU Spy to figure out what is draining your battery.
Ignore percentages unless you see noticeable changes in drain. If something else's percentage goes down, AOS will go up even if it's draining the exact same amount per hour.

Ok thank you. I just wanted to make sure that something wasn't wrong with my phone. I would hate to have to get a different one because I've grown attatched to this one LOL. I did download the 2.3.6 update when it came out but quickly used the Odin oneclick and went back to 2.3.4. Could this have messed it up somehow?
Thank you again,

Hi guys,
Since the update via ota to xxlpq (polish unbranded phone) my battery life has gotten real bad.
After 1h out of charge in the morning, I'm down to 70%
While on 2.3 I could get two solid days out of the phone.
Any idea why that may, be and what I can do?

Install BetterBatteryStats, let the phone run for 8-10 hrs.
Then go to the BetterBatteryStats thread on here, read the first page & the last 10 pages which will give you an idea of what info you'll need to post in order for the guys who regularly post to thread to maybe help you out/identify wakelocks which might be causing your CPU to get hammered/battery to drain rapidly.
There are many customized rom you developers section...you should try to change... i've tested many ics roms and usually have a very good battery life!!
hi guys,
so after much hesitation, i upgraded my phone to the latest stock at&t 4.1.2...here is what my config was prior to the upgrade:
Android Version
4.0.3
Baseband Version
I7777UCLE5
Kernel version
3.1.0-rc8-Siyah-v4.3.3-nomswap
[email protected]))
Build Number
IML74K.CLE5
I used to get decent battery life with the above setup...but after the upgrade, betterbatterystats is reporting 7%+ battery loss per hour...in order to narrow in on whats causing this massive drain, i have disabled all of the custom downloaded applications using titanium backup. Despite this, nothing has changed...
before i start to head over to the custom rom/kernel, i wanted to seek out to see if anyone else who upgraded to 4.1.2 is having same issue? and/or if there are any other suggestions on the battery drain?
Thanks for any constructive feedback...

7% per hour is excessive, even on stock kernel.
Read through this thread in the General section to get an idea how to identify and solve battery drain issues. You may need to root the phone first, if you haven't.
Also, if rooted, you can use the application Greenify to help determine and also hibernate applications that drain battery life.

yeah i also thought that 7% was very excessive....i am already rooted, and doing all that i can do identify what is draining the battery...i did see that you had mentioned Greenify in some other thread, shortly after i posted this...since then i have installed that application, and trying to figure out how to use it...
thanks again
Edit: sorry wanted to restate that i have disabled all of the custom downloaded applications...
Greenify is a great app!
If you just recently upgraded to 4.1.2 then you likely updated your Google play services. Google search it. It has been draining battery like crazy on lots of phones.
Try turning off location services or hibernating maps or Google now.

Hi everyone!
Some days ago I bought a new battery for my S3 (seller said to be genuine) and I am disappointed because its performance is almost the same as the one I was experiencing with my old battery (18 month-old battery). For this reason, I have been researching and I have done this until now:
*) Being honest, this comparison is somehow subjective since apart from the battery change, my S3 was officially updated from 4.1 to 4.3 almost at the same time I changed the battery. Then, I wonder whether this update may have affected my diagnosis on the battery duration.
1) According to the point * I decided to do a battery calibration "without root" consisting in draining the battery to 0% and charging until 100%. I haven't seen any improvement doing this.
2) As consequence I analyzed wakelocks. I have addressed two of them from the System:
- AudioOutLock. to fix this one I did as recommended: disabling sounds when typing and all of this.
- Backup. Fixed by disabling the backup from Google (I would like to have it enabled but if it is causing a battery drain...)
3) I let the phone the whole night turned on with the 3g connection on and I got a ratio of 2%/hour draining. I have read this is more or less under the normal parameters.
After doing all of this I'm still not happy with the performance. Usually, my mobile gets under 20% by the end of the day with the screen on in a range between 1h30m and 2h. If I remember well at the very begging (when I bought my phone), I was getting my phone at 20% by the end of the day but having the screen on for 4h or more. After buying a new battery, I was expecting to return to that situation.
Do you have any hint? As for example a better way to calibrate? Factory reset may help? Should I check a specific wakelock?
Thank you very much in advance!
I forgot to mention that when I let it charging over night, my s3 does not always charge until 100. Sometimes it's until 98 or 95. I don't know if this helps you guys as a hint but I want to provide as much information as possible.
Thanks

Thanks!, I will check. But so far I have briefly seen it looks like there is not a specific solution more than disabling gNow and some other things. Maybe a good option is to downgrade or using a custom rom in which there aren't these problem.
its same to me.
aftet update 4.2 to 4.3.

Hi, look for XDA-forum "Better Battery Stats", there is an excellent tool to analyse battery drain and the community in this thread provides very good support.

Thanks!. I have been using Wakelock detector but I will try with this one. I was wondering if using this kind of applications for checking the wakelocks may provoke some battery drain itself. I mean, should it be used just for analyzing when you experience a battery issue? or should they be permanently installed no matter whether you have battery problems or not?

Hi, Better Battery Stats is using an already existing process of Android to obtain it's information, therefore the influence of the app itself on battery drain should be negligable.

Thanks for the info!. I have not seen anything special in the partial wakelocks. In the kernel wakelocks, it is difficult to distinguish whether one entry is specially problematic or not. After what I have read so far it may be the mix of social apps I have now installed:
- Whatsapp
- Twitter
- Messenger (FB messenger)
- Line
I guess maybe I have too many of them reason why the battery is draining more than normally when the screen is off

Which firmware you are using. .Sometimes it's the problem with the firmware. .For example GML2 and ML4 version firmware has a pretty bad battery drain. ..

mk6 is fine with the battery...so firstly install an app called better battery stats search for it...install it and let the phone to be in standby mode for 4-5 hours..and then see in partial wakelocks and kernel wakelocks..and post those screenshots on bbs thread...someone will surely help you..
sometimes changing kernel could solve the problem..boeffla is the one i am satisfied with..and agni kernel is also one of the better kernels..:good:

Sorry for the delay to answer, I've been busy. Here I post the images of the battery stats. Sorry, they are not what you told me to be having them 5 hours quiet (that's difficult for me). However I can tell you that the 40minutes of screen on where just chatting on whatsapp or checking emails; no angry birds or need for speeds hehe... Are these images ok to be posted on the thread you told me? Thanks in advance!
I had a poor battery perfomance after upgrading from 4.1.2 to 4.3 until I've disabled fast dormancy. It seems that in v4.3 is enabled, and if your carrier doesn't support it, it will eat your battery. Donwload free from market "fast dormancy togle" by Siyah, and that's it

I have just rooted the phone and disable the fd. I hope this works!. Thank you very much for the info. However, now that I have it rooted, do you suggest to install a custom rom for getting a better performance? if so, which? there is a good one with 4.4 and multi-view?.
Thanks in advance!
Try flashing allblacksback mod it makes the whole system dark and saves battery on display and also I recommend disabling Google play services but this means there will be no push services but it saves a lot of ? ? ? ?

After giving a try to the idea of disconnecting the fast dormancy here I give you some reports on the battery consumption. I don't know why but statistics are wrong from the point of view of the duration (3 days).. since I disconnected it just 10 hours ago. I think its consumption is still huge. I hope you can give me a hint on it. Thanks!
Ive installed smartdroid. Battery perfomance seems quite better now! What do you think from the screens? However.. i find the screen too much consuming.... ive seen people managing 5 hours of screen in a day. Why i am not? May it be battery or configuration?
Thanks!
Do you have any hint on this? Ive seen that with the screen off the consumption is really good. However, with the screen on a doing normal stuff: chroming, feedlying or whatsapping it goes to a 20-25%/h.
Hi everyone, I have a really annoying problem with my device battery being retarded and draining from 100% in 3 hours.
Literally 4hours ago I turned my phone on (still plugged into the AC).. I picked it up and started to do my dailies and my phone is just sucking power.
I have no real clue as to how to stop this ridiculous draining problem. This has persisted through 2 new batteries (Samsung official branded) and ROMs ranging from stock S2 firmware to my latest PAC-man ROM
Please see below for images and any help would be greatly appreciated.
Thank you

You need BetterBatteryStats logs/screenshots, those ones you posted don't glean any useful information. Find the BBS thread on here, install it, let it run for a couple of hrs/a day/whatever.
Then (if I was in your situation), post your logs/screenshots to the BBS thread. You're far more likely to get useful (and somewhat prompt) help there than posting to Q&A given specificity of this issue & how relatively little traffic Q&A sees these days (chances are you'll either wait ages for useful responses, or get fed generic bull**** which won't help).
it could be a wakelock issue but only can be confirm after you install BetterBatteryStats......
i believe you can tackle wakelock issue by using greenify or Wakelock Terminator....
If you have root you can try Wakelock Detector.
With it you can see if some application keep your CPU awake.
