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.

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.

This might just be the ramblings of a mad man, but I have been thinking lots lately about battery calibration on the sgs2.
Normally on most android phones the power off charge is completely independent from the rom so that if you charge when powered off you know it is really a full charge, not controlled by pre-logged battery stats, you can then wipe the stats and get a better idea of what "full" is when you are powered on.
On the SGS2 the charge when powered off is still controlled by the rom (see the app "no moar powah" for an example of this), therefore it may still be under the control of the same battery stats so may not indeed charge any more than what the rom thinks is full when you are powered on.
Wow, thanks for your explanation...
But, it makes me perplexed. If you're alright, you mean that battery calibration doesn't work on S2 ?!
So, in this case, how to solve my problem ?

the best thing you can try is to run the battery flat, charge while off, wipe battery stats anyway and hope for the best.
Will try it again ....
Maybe should I flash another rom after full wipe, or stick to a stock one.
I can't imagine that my battery is defected yet !
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 ?)

Is that the same as doing it through Clockworkmod advanced/wipe battery stats?
It is normally the same thing, I prefer IMO to do it manually.
Just trust yourself
so as im a new user and i can't post in half of the forum, but i've still got this urgent question/ point to ask, here's my question:
i recently moved on the new 1.9.1 ressurection remix rom from the 1.3, and aswell changed my kernel to siyah, now lately my battery drains preety quick (yes i did burn it down to 0% and charged it over to 100% few times), but here's the thing, when once i had issues with screen burning 30%-45% of my battery, now it's lying low on 10%-20% while the real issue now is the "Android OS" which goes as high as 60%-70% of my battery, i've been trying to calibrate the battery and reset battery stats and discharge and recharge couple of times, but this just keeps going on... any way to solve this?

OK! I've read your situation. This is the only thing that I can recommend. Try installing a Gingerbread rom and see if the issue persists. If it does then some of your application could be the culprit behind the battery draining issue. But again, thats just a guess...And if it is one of your applications that is causing the drain then you should install bettebatterystats from this thread:
http://forum.xda-developers.com/showthread.php?t=1179809
Then charge your battery to 100% and try a new calibration method, maybe you haven't heard of it. But if you charge till 100% then take out the battery for exactly 3 minutes and put it back in and power up your phone and use your phone normally as you do and then at 20% or lower go and check betterbatterystats and see what is causing the most of the battery drain.
Have a great day and good luck with the battery drain, hope this helps!!
Did you check the ROM FAQ about battery draining?
Please check it out. There is also an example of making some changes using extweaks which comes installed by default with ICS Resurrection 1.9.1.

i did read about the new method today, but havent had the chance to try it yet.
im not sure if it's a certain application that causes it, but in the battery stats it points out "Android OS", i've seen many galaxy nexus users complain about the same problem, even with stock kernel/roms, and galaxy S2 users that moved from gingerbread to ICS. it's logical that ICS will take more battery because of the control over multiple cpus and all this kind of stuff but im not sure how much it is about that "Android OS".
anyway ill try to have this battery calibration new method once my battery will drain out, and im probably not going to go down to gingerbread again because i already know its not gonna persist because i remmember how my phone behaved on GB and that those 2 systems work completely different and i want to solve the drain per ICS and not solve the issue by downgrading back down to gingerbread.
thank you for your time and help anyway

hi
is it required to battery caliberate after flashing new rom?
and when ever i reboot my system either battery jumps from 10% to 30 or more
or becomes less than 10%..
if i should then which app should i use?
any guidnace
plz
TY
No such thing. After you flash a new rom, charge the phone to 100%, turn it off, remove the battery for 30 seconds, replace the battery, turn phone on, enjoy.
Anyone selling you the whole calibration thing is selling you voodoo.
hi
thanks for your reply
plz suggest me best battery app with battery saving feature , suggestion on what we can do with remaining battery , expected full time charge , complete graph or battery usage history by apps?
paid or free , tell me best one
thank you
There's lots of battery apps on Google Play, there's no such thing as the best one, go have a look under the Tools section in Apps (you'll also find some under productivity). Stay away from apps like Juice Defender that claim to save you battery by doing things automatically which you can do yourself in two seconds, these have been proven time & again on XDA to use more juice than they save.
ivl try battery monitor
thank you
No probs ;-)

Wouldn't that procedure above be considered calibrating the battery? LOL. J/K. Couldn't resist .

actually it cannot. this way you only help the system in your phone recognize full capacity of battery (which is not even full because not one battery works at it's full capacity - but it's fullest you will get at this point of your battery life). when it's about calibrating - listen to MistahBungle - it's all voodoo. you cannot calibrate li-ion battery unless you kill it and then revive. by killing it I don't mean depleting it in your phone, because even when phone shows the battery is fully depleted it's really not - there is still some juice in it. you'd have to use e.g. special charger which can drawn juice out of battery and make it really empty. only then your battery is dead and useless. you may revive it by applying cca. 5V but actually it not always works. so you cannot calibrate your battery in home environment.
what you can do is "re-calibrating" so called fuel gauge (description under links given below) and you may also help your system recognize the real state of your battery charge. sometimes it happens that systems readings are wrong and battery is on 85% but system is reading it as 50 or 100%. to help it read battery chip correctly you do the thing MistahBungle so helpfully described. sometimes you even don't have to do it but wait 2-3 charging cycles and system will adjust it's reading itself. by charging cycles I mean charging like from 20-100%. why not from 0%? because even if it's not a real depletion state, li-ion batteries doesn't like the state of being discharged too much.

and is there any way to stop auto startups of apps?i have around 200apps and most of them i use around once a day or not even once
i use android assistant to manage startup but it does on boot and after some time if i check running apps most of apps will be there running
is there any app to block it running automatically? not just at startup ? full control like anything?
thank you
actually I cannot help with that. I don't use such a software and really don't believe in it. but, the fact is that I do not use so many apps. other fact is that surely there is some useful software that could help you with that task, i just do not use one and personally I'm not interested in it. I know that perhaps the best method is to freeze them with titanium but if you use these apps from time to time then it would become complicated and not worth the effort.
still I have few questions:
why would you like to stop them from working? do they drain your battery? if so then check your logs with bbs and find out which ones are draining, try to change their setting or get rid of them, or at least close only these ones. long time ago I was fighting with some apps that I do not use often and they start themselves from time to time. I didn't want to get rid of them, so before every night I was killing them one-by-one from applications menu (actually most of them didn't wake up until I ran them myself). finally, after many tests I got to the point that it doesn't make any difference. apps I was killing, even if running, didn't use any recourses, didn't produce wakelocks, they were just using some RAM. and if it is the reason of your concern then do not be worried - they may use as much RAM as they want - android will free RAM when it will need it.
now I do not kill any apps and by night I lose 0-2% of battery which is my only concern - what should we care more? CPU, RAM - let it work as long as it doesn't stop us from enjoying our phone and make a usage of it uncomfortable.
and if you're worried about packet data then you may limit it for each app using system menu in ICS.

Thanks dude. I also have the similar problem. I have spent months on it without any improvement. Now I'm quite frustrated and not optimistic on the solution you have provided towards my issue, but your decription gives me a lot of clue.
But my problem is even more tricky, I would like to share it here so see if anyone have met it before, or if I need to start a new thread to deal with it:
The problem can be generally decribed as below:
1. When the battery is fully charged, unplug and consume the juice until the level reach around 30%, then the phone is shut down automatically; after I plugin the power and restart the phone, the battery level is displayed as 0%;
2. After charging for a while from 0% , restart the phone and you will see the battery level directly goes back to 50%, but still with very low voltage;
3. Changing with a new battery won't solve the issue -- though the new battery itself may also have problem(not sure if it is genuine), but I don't think a fake battery and an old battery should behave almost the same, so I don't think it is the battery's problem; criticize if I'm wrong
4. Re-flashing a new rom won't solve the issue either. I have tried different CM9 nightlies and now I'm using CM10 nightlies, none of them is immune to the problem;
5. Clear the battery state won't solve the problem. It is hard to say whether it improves the situation at least a tiny bit. I mean it may work somehow, e.g. My phone used to be shut down at 50% battery level and now it can last to 36%. But it never totally solve the problem once and for all, so I still don't trust this caliberation thing may work.
I hope I have clearly stated my issue. I'm so at the end of my patience, this little bastard have been always torturing me You guys are the last I can count on I really hope I came here earlier so as not to have wasted so much time.
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.

although the wakesleeps could be a problem I would like to know why I can't use the phone permanently for some hours ..

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 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.

So, all those stories, which you have heard about batterystats.bin file removal improves battery life is false and just a placebo.

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.
