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.
AJ
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,
My battery drops after every abnormal shut down, by pressing the power button for ~8 second. (I do this when the phone freeze.)
And when I turn my SGS2 on, some battery "disappear", sometimes 10%, sometimes 20%, or ever 50%.
For example, I have 90% of battery right before I shut it down (abnormal shut down) , and maybe I get only 50% of battery after I turn the phone on. It that possible that the battery drains 40% in 1 minute? Or it is normal because I shut it down improperly? (have a look of the attachment)
There is no problem if I reboot it normally.
I have two battery, having the same problem.
I face this issue in many ROMs, stock GB ROM, AOKP ROM, MIUI, etc.
I'm using Siyah Kernel 3.1.2 now.
Thanks for any help
(Sorry for my bad English)
I've heard a few users mention this battery drop and i've experienced it myself. It even happens sometimes if i restart my phone after flashing a mod or something.
You'll notice that the battery level starts to climb back up to where it left of (less the normal usage discharge)
Yep, normal on the SGS2.
Just part of the battery weirdness as a result of that fuel gauge chip. Entropy512 has written many a post on the subject if you feel like searching/reading up on it. Nothing to be alarmed about tho, and nothing you can fix. Just make sure you've got plenty of battery left before you do a flash.
On other hand, your freezes if regular is a worry!

Yup, my SGS2 freezes quite frequently after upgrading to Android 4.0.4.
Maybe I'll downgrade to 4.0.3, or perform a full wipe and flash the ROM again to fix this.

Battery drop is pretty common say 7 out of 10 times if you remove battery, after boot you will be 10-20 percent less. Specially if you change roms quickly..

Apart from the first few words of what you said (which I've omitted), what does the rest of it have to do with the OP's query about battery dropping after a dodgy shutdown or when flashing firmwares ?

Hello,
The problem seems to be calibration of the battery with the phone software.
After you root and install CWM, you can wipe battery stats. Doing that will erase all information of battery from the software and information will be made again as the cell discharges.
Other option is to root and get an application for battery calibration from the market. It also does the same thing as cwm.
Thanks,
Rick

i had 10% 'miscalibration', when charged to 100% and unplugged percents dropped suddenly in couple of minutes to 90%, and when battery was almost empty at 1% i could use phone for a good time playing 3dgames (just like it was 10% not 1%).
so when next time phone was about 50% battery i started cwm and wiped battery stats and then used it normally to full discharge and then full charge and now i have perfectly calibrated battery. when indicator says 1% i know it will be shutting down in a couple of minutes and when i have charged it to 100% it remains at 100% even for an hour if i leave phone in idle.
I got similar problem. I havent root before so i just make few fully charge and discharge and havent problem anymore. Just also try keep it loger on charger (even when you get 100%) i thing is realy dont need for most of this problem software tweak if you havent some defect mobile.

But the user just a floor down the quoted comment says it worked?
If not batterystats.bin, then there has to be some file from where the Android OS takes reference of to display the battery percentage? Or there's another possibility that the OS builds the percentage at real time, each time checking how much juice is left. Or is it something else? .
And this is a very common issue, as far as I know. How to get rid of it then? If wiping battery stats from CWM is not supposed to help?
Thanks,
Rick

Check your battery consumption, does your phone enter sleep mode or awake most of the time?
Any apps running itself on the background that maybe draining your juice, or maybe your 3G/Wifi/Bluetooth settings.
Its not about apps I thnk bro. Its a problem in the android OS Itself. That's why im looking forward to install a custom Rom. But I don't know a single little thing about how to install a custom Rom.

Go Here http://forum.xda-developers.com/showthread.php?t=1568792,
and check out the procedure to downgrade your firmware. Downgrade to .58 firmware. Then root using http://forum.xda-developers.com/showthread.php?t=1321582. So you will have .58 Firmware with Root Acess.
In case you want to update to .62 now, update over the air, using Update Companion.
Note: You might loose Warranty while following these steps

when you repairing your phone by suse
you taking the sim and memory card out before repair (service center way)
try this make sure its 100% battery
take sim and card out repair tthe phone
when done put sim and card back in
and test
if it still happens it could be a buggy firmware
lets us know how it goes matey
i also once had diz mis calibration.from 30 % it suddenly went to 1%.now my problem is solved.i am .58 firm.i did the following
1.installed battery calibration for root users and calibrated..
2.wiped battery stats with cwm
these things only worked for some days only..den i did another two things
1. bought an original sony charger(mine was not sony's..)

Have you tried battery calibrator included in v6 supercharger forum? Try to check it out though havent use it myself since I dont have problem with regards to battery. Also try to install/search battery drain app fr the market. You can monitor percentage drop per hour on ur phne using that. Mine had around 1.5-2% per hr on normal use and 0.5-0.8% on deep sleep mode. Average life of our battery is around 1.5day at normal and can reach 4days atleast when on idle(no activity). Readings fr here are taken not from airplane mode+stock rom and customized kernel.

For this kind of problems i recommand to you to:
- charge your battery until it's 100% fully charged
- remove the battery and wait its 100% charged
- then reboot in CWM and wipe battery stats and reboot, and unplug the phone.
its is depend on ure KErnel
.no need to wipe batterystats...i hAve facing more worst bttry clbrtion prob for a month..batterystats dun do anything with ur battery or else..its just a stat that tell u what app has eat ur batt juice..wiping batterystats can't calibrate ur batt..trust me..ur phone will calibrated itself
..
1.use u phone normally..
2.fully drain the battery until it shut itself..turning on back until it cannot be switch on..(completly drain)
3.open ur phone back rear cover.plug in ur charger..i recommend charge ur phone without turning it on(offline chrging).just wait until it fully charge.(green)
4.turn on ur phone..use it normally..if the prob still stick..do it again.
give me an updAte..and i give u another method..just keep in mind.android calibrate the battery itself..its been 2 month finding this solid fix and cause..i have more worst prob..u cAn check out my post..

Hye everyone, my name is Ruben and I am 35 years old, I have a small goatee and my hair is thinning and I have a question.
Yesterday, Before I flashed a new ICS rom, my battery life is at 83% and after I flashed the rom my battery dropped drastically to 14%.. and after a while my battery started to increase to 16%,17% and after a while I ignore it and charged until it reached 100%, no issues until now..
My question is why is the battery indicator behave like this? is it okay to ignore it... If it doesn't what should I do to repair and avoid this.
p/s always do the 4 wiping before flashing to public.. sorry.. before flashing new rom. using 1 rom only, and from ICS to ICS.
Thank You.
Yes it's normal, the battery percentage does that when you just installed a new Rom. Leave it a while and it probably will settle. If do not, and it is actually a pretty normal thing with my phone, change the kernel (latest Siyah Kernel, 3.3.2, it makes my battery icon goes insane).
And it happens more often when you reboot your phone.
So.....

Why the battery goes crazy more often if I reboot my phone? can you give me scientific evidence on this behavior. Is this only graphical glitch or it directly effecting the battery itself. btw my battery only goes crazy only after flashing certain new rom.
p/s: maybe siyah 3.3.2 is a steroids for battery, yeah!! gokhan steroid...

Happens to everyone. Give it a full charge/discharge cycle to settle. 'Scientific evidence on this behaviour' ? Search XDA. There are dozens (at least) of threads/posts that have been written about the 'battery weirdness' of the SGS2 in the time I've been here.
It's a statistical glitch, nothing more. If it were happening with every rom you try even after that initial charge/discharge then maybe it's an issue with the battery.

No, it is not the kernel. It is a bug in the ROM, that hasn't been found or fixed yet. Restarting resets certain phone data.

It has happened always since ICS update for me, with all ICS ROMs I have used, with all ICS kernels I have used.
Restarting does the deal. I restart my phone every morning anyway, to clean up the memory/CPU, so phone will be faster.
It dosent happen with stock extended kernel..earlier it happened to me when I switched to krsh kernel aftet that I flashed extended kernel and and install custom rom like rs lite. With wipe data and format and this bug dissapeared..then it never came back
Hope it helps

In my experience so far concerning battery life, the kernel plays a huge role.
Stock kernel is a big drainer. Rage kernel is very good with battery life, as is KRsH kernel.
Flash a custom kernel, and set CPU governor to smartassv2, svagedzen or brazilianwax. Those 3 are in my experience the best.

Thought so.. that it was related to the Kernel.. I'm on extended stock kernel now and the battery life isn't as bad as stock ICS. Although I really haven't kept track of the exact battery life on this kernel, but it's certainly better than Stock ICS.

I've had similar problems when my usb port got burnt, and battery indicator constantly kept showing 'charging' icon, even thought cable was unplugged. Apparently some process/service (related to USB connectivity) prevented OS to go to sleep, and that kept draining the battery... Thanks to warranty, phone got fixed, and since i havent experienced any battery drain. Last time i checked, i got up to 3 days without recharging the battery
