Hi. A friend of mine has an unrooted GS2 (android 4.0.3, baseband JJLP8) For a week now he has been having serious battery problems. Like when he uses his camera the battery can drop 30% ina few minutes...
A few places that i checked suggested to reset the fuel gauge chip using an app like extweaks. But because the phone has stock rom & kernel thos kind of apps dont work.
What can i do withous first rooting his device?
Thanks, shlomo

You can't 'calibrate' the battery. No such thing.
Charge to 100%, use the phone.

Install betterbatterystat(bbs) and check what is causing wakelock. And we need more info like is data on or wifi on the whole day?

Your phone is not going to deep sleep.install cpu spy and watch the frequences because i think one app is not letting your device to go te deep sleep hope this helps

As it shows 60-70% used by 'Android OS' then it must be some app like thing!!

Just so you know data used quite an amount of battery. Wifi is better than data on term of battery use.

i had something similar not too long ago, and it was also happening first few days when i bought device the most:
http://forum.xda-developers.com/showthread.php?t=1871454
after few days my ICS and my battery made some sweet love i quess cuz i now have decent battery time.
read trough the thread, some say it really could be OS "learns" after some time about your battery (calibrates it)
some say its not that, anyway, i dident do anything and its good now.
cheers

Did you follow the advice of LexterAce in post #2 and install BBS?
If so, why not let it collect information for 5 to 10 hours and then analyze the dump? Almost always the dump can help you to find out what keeps your phone awake.
If not you could also post the dump and maybe someone else can help analyzing it. In the BBS thread are many useful tips and links about how to read and interpret the dump.
Hi, did you resolve the battery problem?
I am in the same situation, can you give me advice guys?
Thank's

My battery (original) drains even wen the phone is off. First i tought that my battery was broken. I bought a new accu (original) but i got the same results. After about 8 hours ive got 15% less juice and the phone was off. What could this be?

Try to 'callibrate' your battery, and see if gives you the same results or if it's fixed: Charge your battery to 100% - turn off your phone - remove your battery for about a minute - replace your battery - turn on your phone.

I think that it may be caused by the internal GT-I9100 Battery Fuel Gauge chip, you should ask a service center, often problems like this are because of internal battery chip failing at equilibrating charges between battery cells.
You should also try to reflash a stock samsung rom (like XXLSJ) using odin, so if there's any software problem it should solve it

About deep sleep i already checked vefore and it does but as for better battery status i just downloaded the app. Should i just let it installed and dont touch or do i need to run in the background?

Some parts of it need root access. But it should still give you the wake locks. Just let it run in the background and check it after a min of 5hrs
Is that good for you? That's all it matters.
It looks alright to me.
Can it be improved? Of course.

I think you have several times recharge the battery to 100% and also drain the battery until phone turn off to calibrate.

Hi, my wife seems to be having an issue with charging her smartphone. Over the last month or so her phone has been taking longer to charge, I have the same phone but the international i9305 and it charges allot faster. We are both using CM 10.1 custom ROM which I have just installed on her phone, prior to this ROM she was on the stock ROM JB 4.1.2 but still facing the same issue. The battery is currently at 72% charge which has taken 3hrs 8 min so far. Is anyone else experiencing the same or is her battery on its way out? :banghead:

For a better overview of what is eating the battery along with charging and discharging rates, please give a try to 'battery widget reborn' app. It will also inform about the battery health, so that you can know if you have to replace the battery. All the best bro..

Just a quick tip.
Dial *#*#7378423#*#* then go to Service Tests >>> Battery Test.
It will take some time but I think you will be able to identify if the battery is defective or its just a software problem . Hope this helps

Try installing a custom kernel that allows you to change the input current when you charge. Siyah kernel is a good kernel, increase it up to 1100ma and see if there is a difference. If it worked, the phone should now charge faster than the unmodified phone; if it doesn't, it is a hardware issue which you should take back to Samsung.
Please suggest a good app for detecting battery drain.
The original chargers for the s3 are known to be faulty/erratic...might be that you have one of those with your phone,I use my old s1 charger and USB lead, as do many, or s2, anything other than that POS they supplied with the phone!
UPDATE: thanks for all the suggestions folks, not sure what the go was but all is good now. Full charge now only takes 1hr 20 min, haven't done any thing different just doesn't take over 4 hours anymore.
Cheers.

Try using the Easy Battery Master.
It have a formidable option called BOOST who kills all unused apps and services every 5 minutes(need be configurated to it) and also show the remaining battery in time calculated by your current usage status. This app give me something about 2-3 hours of extra battery daily.
Thanks Guys! I will try the methods! Hopefully my stock 4.1.2 battery life will improve

Then get a regular genuine battery.
After it's first year my battery started to last less and less. I've replaced it and currently having great battery life on CM+Dorimanx.
