Dear XDA-devs,
I have some problems with my galaxy S2, the major one is the battery lifetime.
When using the device, it drains superfast. I can not use the device for even 6 hours.
Because I can't afford to buy a new device I am looking for an solution.
I thought that it's a software problem and flashed supernexus rom but the drain is still there.
The overcharging ( 0% to 100% then taking battery out, turning off device and charging again) had no effect.
Battery drain (from marketplace) logs changes of battery status.
The log attached is a disaster.
So my question to you: How to track and solve the problem?
Thanks in advance,
Alex
I think its the kernel problem. Keep ur phone clean from unwanted apps which run in background, stop unwanted services such as wifi, lower the brightness, keep ur phone uc/uv as much as possible, try to be on stock rom as much as possible, increase the screen timeout and clean the battery. Thats all i can recommend

I dont understand the language in the attached pic, so thats not much help. All I can suggest are the usual suspects for battery drain.
Install CPU spy to check the various states in which the phone runs. Is it going into deep sleep like it should? If its not, thats your problem right there
Another thing to do is install Better Battery Stats (search the forum for the thread) and use that to check for unnecessary wakelocks. Additionally, I don't think what you mentioned (overcharging) is a way of calibrating your battery..although I could be wrong there.Instead you can use any battery calibration app, or if on siyah or dorimanx kernel, use the 'reset fuel guage chip' option in ExTweaks. else there are threads about calibrating your battery without the use of an app.
Or if none of the above works, you probably just need a new battery. Definitely not a new phone

Dear Alex,
have a look here => http://forum.xda-developers.com/showthread.php?t=1179809
It is BetterBatteryStats app thread.
BBS app is very useful to examine the battery stats and find wakelocks (prevent the phone from entering into deepsleep state) and alarms (activate the phone when in deepsleep state).
You can examine the BBS log yourself or just post your log and stat files to this thread to be checked by the "experts".
Good luck !
re
Hi HAXTREME,
thank your for the reply, the app shows the time when the battery decreases by 1%.
As you can see it loses 10% in some minutes ..
I will install the app the other poster mentioned and post results here..
thank you both.
// edit
although the wakesleeps could be a problem I would like to know why I can't use the phone permanently for some hours ..
as I remember this was possible when I bought it
Stats after tracking
Hello guys,
I have tracked the battery stats during 2 days now and it would be great if you could take a look.
Do you see something suspecious?
Do you need more information I can provide?

At the very top of your dump file you attached, it says:
Statistic Type: (3) Since Unplugged
Since 1 h 3 m 55 s
You need to let it run for longer than this after unplugging. BBS will reset stats and start a new dump file when you unplug the phone.

Hello guys,
I have a problem with battery :
Every morning, after booting, my phone was powered off over all the night, I can see my battery decreasing by 10%!!!! And I sometimes notice after few minutes that it increases itself bit by bit...
I've already did a battery calibration, but not after flashing the new Siyah' 2.0 kernel.
This is very annoying, and makes me wondering if I should recalibrate or what...???
BTW, the question is : HOW ?
Some say you have first delete batterstats, power off, then full charge.
Others say you have to power off, full charge, manually delete batterstats.bin, or use Battery Calibration App.
What is the f*** best way to calibrate our battery ?
I'm really pissed off loosing 10% battery with my phone powered off every morning...
Regards.
Using Revolution 2.7.1 ROM with SiyahKernel v2.0
Was there really any need to create this thread in Q&A and then 30 mins later create the exact same thread in general?
If you read the FAQ on the SiyahKernel v2.0 thread it clearly states:
Q: do I need to recalibrate the battery?
A: You don't need to calibrate battery for SGS2. Thanks to Entropy512 to pointing out that our device uses MAX17042 which is specifically designed not to require calibration.
Therefore it is not a battery calibration error, you should get your battery checked or replaced as it may be faulty. Good luck!
Of course, no.
Sorry for duplicate that thread.

I've already read it.
But the fact is I am not the only one who gets issue with battery calibration, when flashin new kernel/ROM.
Shall we all replace our battery for a new one ? I don't think so at first sight.
In addition, many people notice calibration really works and make the battery more accurate than before... Common placebo or what ?
Hmmm...
It's definitely weird if powering off your device still drains as much as 10% overnight. I don't think any battery calibration can stop the phone from draining when off.
Have you tried reflashing a stock rom? From my experiences, the stock rom gave me the longest battery life when I first got my phone, but that may just be the fact the phone was new.
No, I've been stayed with Revolution ROM for a while.
At the beginning, never had this dropping issue. Seems to starting after flashing Revo 2.7.1 and Siyah' kernel, but not 100% sure.
It is very strange cause, I use it normally and battery is working fine : no decreasing on deep sleep.
Maybe this could help :
Just after full charging, use Battery Calibration App, and notice it didn't delete Batterystats.bin in data/system... I've always use it and never pay attention... (maybe error with SU permission ?)
Very strange, so this time I delete it manually.
Hope it'll calibrate my battery well this time.
Wait n see.
My first current conclusion :
The best way to calibrate your f*** battery is definitely to do it manually.
Just delete batterystats.bin in data/system, after full charging (with Rootexplorer or another app)
Then, use it until to 90%, and full charging.
That's all ATM.
Why ?
Because, I've just noticed that Battery Calibration App doesn't always delete this file. Ya, sometimes, It works, but sometimes It sucks. I don't know why, but seems to be related to some SU version and permissions' bugs...
Hope it could help some of you.
Hey guys!
Have a little question my battery drains down during night from 85% to 35 % don't know why.
Have checkrom v6 and neak kernel with undervilting. What can be the fail. It went into deepsleep but "Android Os" is working all time?? 16 hrs lifetime and 10 hrs cpu usage very strange

Install BetterBatteryStats & let it run overnight again. You've obviously got wakelocks keeping the phone awake & causing the drain. BBS will help you identify these.
You can find it in the thread on here or on Google Play.

have installed BetterBatteryStats now.
i need to look at the "Partial Wakelocks" ? or where can i look for?
//
is there any problem? have made some screen captures !
You need to let your phone run for a reasonable amount of time to get meaningful stats from BBS (6-8 hrs/overnight in your case given the drain is happening overnight).
Edit to add - Yeah, partial wakelocks are where you need to look. Just having a quick look at those that alarm clock you're using obviously has a few, as does GTalk (doesn't mean you're actually using GTalk, this means something on your phone is/was trying to communicate with Google servers, and Facebook service as well.
I recommend having a look at the BBS thread on here & if necessary post your screen shots there. Guys who post there regularly will be more likely to be able to give you specific help than me.
Further edit to add - Don't waste time/money with 'battery calibrator software'. Everyone (should) know(s) it is not possible to 'calibrate' an SGS2 battery Also, Google have confirmed delete battery stats does exactly that - deletes battery stats. Nothing else. Has no bearing on/doesn't affect anything.
i can tell u the usual
try recalibrating ur batter through battery calibrator software wipe battery stats from cwm if u are rooted and try turning of 3g and lowering brightness

Hello everyone whenever i check bbs or gsam battery widget or wakelock detector there is no wakelock but the thing is that after 1 hour or so whenever i check my phone i lose 5-6 % .That means not even 1 day of standby
what could be the problem? i've tried like 20 roms and different kernels and still have this issue..
Im currently using walkman style rom and Kappa kernel

Which is your current ROM and kernel?
To fix this you could do the following
1. Reflash the phone's stock OS(preferably GB or ICS)
2.Just in case re-calibrate the battery via cwm or an app.
3.Run with the stock ROM for a week without installing any other apps.GO STOCK!
With this you can know if the problem is ROM or Kernel or you battery.

Force deleting the batterystats.bin file is battery calibration. This is the closest thing a user can do to properly set up the battery monitor chip.
The file is used by the chip set which monitors the voltage across the battery to give out the % reading. It's normally reset by the chip itself if we charge the phone up to 95%+ each time. But improper flashing of roms will cause residue data to remain resulting in a error in the %.

Wrong. I have no idea, where you are taking this from, but this is completely false.
Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

Well thank you. You've completely changed my conceptions about battery! I apologize for any wrong information I may have provided. So I ask you is there any other way?
Right now my phone switches of on 10% all these days I've believed it was just a file problem but since on reading the article I can see it's not. So is there any other way to properly make the phone show the proper battery left %?
Mine dies just at 10% is there any way to correct the problem?

You can try deleting the batterystats.bin file, but I am 100% percent sure, that this won't fix your problem.
Though I have not been active on this section of the forum, I can not provide any other solution. I know there have been other threads, you might want to try searching on the forum, if there are any solutions.
I have got a strange problem.
My Samsung S5830i Galaxy Ace has a battery drain of 50% per night without usage, WLAN off.
The device is rooted, and I've had an battery issue when using Link2sd with a ext2 partition (bcm.sdhc.3 kept the phone awake all time). I fixed it using ext3. This was six month ago, no problems after that.
Since last week, I got this huge battery drain. BetterBatteryStats tells me the phone is sleeping most of the time, no suspicious processes.
I tried with a battery from a friend, no result.
I factory-reset my phone, no result.
I used a ClockworkMod recovery from the time before link2sd, no result.
The battery is still draining like hell.
What else could I do instead of throwing the phone away? Please help!

His Battery is not very old. And I think it would be strange it is really a battery problem, because it happens very sudden and the behaviour of the two batteries is the same.
The phone is 1,5 year old. I think about unrooting and try to make use of the guarantee or to get another rom and flash.
But if it would be a software problem, at least the recovery should overwritten the faulty settings, or not?

I've come from using the ipad air to the Z2 and over night the battery drains by over 50%.

I didn't use the device at all and stamina mode was on. This is frustrating since the ipad can stay in standby for days without even 5% drain.[emoji15]
Anyone?

Well, for starters, not sure if the battery temperature chart you attached will help.
So you say it goes from 100% charge to 50% overnight? If so,you got some serious issues there. Typical loss is from 3-5%.
But 50 is absurd.
When you check the battery usage, what kind of usage is going on? Display of course is a biggie and uses the most. It's possible some application is keeping the tablet awake/display on. This might explain it a little.
I will explain how to read it. If the usage chart states "Display 54%", then it means of the 50% battery you lost, the display was responsible for 54% of "that" figure. That's how to properly read it.
But you need to find out where the drain is. I suspect a "rogue" app or a bad battery perhaps. A rogue app can certainly cause it, as with running some strange mods that just don't get along well. So you are going to have to hink back and remember what you changed just before you noticed the drain.
You can install an app called Better Battery Stats, and it might actually pinpoint what is causing the severe drain.
You have already installed GSAM Battery Monitor, so you should be able to find the cause for your battery drain.
Do you already have the Root Companion App installed, too? If not you probably should do so, this should provide better stats. Your tablet needs to be rooted, though.
After the drain appeared, open the GSAM-App and select ´App Usageˋ or so (my app is in German, so I donˋt know exactly). Then select ´Show Kernel Wakelocksˋ or so.
Now you should see how long your device was awake and what caused this.
Hi guys! Thanks for your help here.
I have found out now that the battery is definitely faulty as it went dead last night and I tried charging for 2 hours and it still won't turn on.
I am sending it back for a replacement.

No problem. At least you know the cause. Personally I can't recall a bad battery on a new tablet, but I would think it's possible as many tabs as are sold. Sucks you got one though.
