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
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 ?)
Very strange, so this time I delete it manually.
Maybe, it'll calibrate my battery well this time.
Wait n see.

Weirdly, I noticed that yesterday! I don't think it works on all roms, I'm definitely going to do it manually from now on.
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.

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
Hi guys I have noticed a strange Battery status..
I had my battery percentage showing above 50%
Then I switched off the phone,
took the battery out for a few seconds,
put back the battery and switched on the phone.
The battery was down by 15-20%
Then it started to gain a few percentage (upto 5%) of battery without me putting it to any kind of charging point/data cable.
What kind of weird thing is this in the Galaxy s2.
I am using Android 2.3.5
Simple&Clean v1.3
Speedmod k2-16
I have also attached a screenshot of it.
Please tell me why is this happening cuz this happens every time i take my battery out.
Thanks
nah, its ok. just a bug which happens sometimes. happened to me many many times.
Or if you are constantly overcharging the battery it will happened .

You can't overcharge if your phone is working right. Its probably just drift in the monitoring circuit.

It's due to Samsung's built in battery calibration. When flashing firmware cwm can throw battery stats off, but after using the ROM for a while it will auto correct itself. Nothing to worry about dude!

hey djsherry, did u figure this problem out? because I have the same and if you (and others) have a close look at your screenshot your phone shows the same amount of time both for elapsed and remaining time on battery!!! Thats a weird situation, I have read hundreds of threads and still couldnt figure that out! Anyone??? Must have a problem with the hardware (battery monitoring) or with the battery itself?!?
Search before posting please, nothing weird about this. It is well documented well understood behavior.
Delete.
Its common, resetting your battery gauge will reduce this to some extent

Hi there,
just in advance: Yes, I have read quite a bunch of battery drain threads, but non of them seemed to help me.
Compared to GB, my SGS2 doesn't even seem to last more than a day in terms of battery life.
Now I wonder - is it just me playing around with (otherwise awesome) CM9 and battery life is actually normal or is there some kind of battery drain going on?
Running CM9 14-04, stock kernel, LPS baseband.
Attached please find BBS stats and other battery stats screenshots.
Help very much appreciated

Awake over 2 hours, 1 hr 43 min screen on, down to 62%. That's on track for 5.5 hours awake time, and about 4.5 hours screen on time. Looks pretty normal.
You MIGHT be able to squeeze a bit more juice out by playing with your sync and display settings, but that otherwise doesn't look that bad.

Sync is pretty much off completely and display brightness was on 'auto'...
the graph looks pretty good without gsf and alarm manager wakelocks
Have you tried to re-calibrate your phone? I once messed around with my battery and i lost 70% battery overnight when it was on 100% because i was unplpugging, plugging my phone in randomly.
How do I do that?
Just bought a 2000mA battery and it seems I still got the same 'issue'...

Download battery calibration app from play store, put phone on charge, wait untill will be 100% charged, open battery calibration app, click calibrate, unplug you phone. Done.

Did you try to wipe your battery stats? Also, I noticed that playing around flashing the Roms, requires 2-3 full charging cycles before the battery was "stable" again
I've also read the following but didn't try it (I imagine it does the same than wiping the battery stats in the recovery, but you never know, you can try it):
Delete batterystats.bin in data/system, after full charging (with Rootexplorer or another app)
Then, use it until to 90%, and full charging.
Good luck!
When is it a good idea to wipe battery stats? When it's empty or at full charge?

The CM9 has some battery drain problems because is still developing maybe try wiyth another rom and see if the problem remains

Stats seem fine to me. Your phone shouldn't drain much when idle, but once that big screen is lit up the power drains much faster. The SGS2 stock battery is not huge to begin with either. Your 2000mah will be better though, especially after using it for a few cycles. You can also try flashing a different stock kernel or custom kernel (Siyah, etc).

Thanks guys!
So charged my 2000mA battery up to 100% now and wiped the battery stats. Hope this helps.
I really wanted to stick to CM9, because I don't wanna do a factory reset every couple of days when flashing other ROMs, because I'm tired of setting up all my stuff over and over again...
Are the other ROMs really that much better? Thought that CM9 would be best, because most popular...
Or could it be the baseband/modem too?
I am on LPS right now... I've searched the forums forever, but can't seem to find an answer for:
What is the best baseband/modem for battery life?

Hi I have read some threads, but cannot find anything that helps me
I have 2 Original Samsung batteries, cahrged both with the dock or AC charger, and cannot reach 12 Hours
I dont have any "strange" app or something that could be draining my battery.
im Using the Paranoid Rom (CM10) and wifi most of the time
wish to know what could I do to improve my battery life
hope someone can help me
(sorry about my english)
Boot into recovery and wipe battery stats also if you have antivirus....get rid of it, drains your battery and is not needed
anyone interested in blu-ray steelbooks, holla at your boy
thank you.
so if I have 2 batteries, I should wipe the stats for both right?
and one more questions, I read and told that if I flash a new ROM, i should wait for some battery full cycles for the battery to
last longer. Does the "wipe battery stats" affects anything?

Hi
as what the first reply said, you wipe your battery stats via recovery..
but to do that, you have to fully charge your phone up to 100% first and then go to recovery and wipe battery stats..
also, any applications such as "battery savers" and "anti virus" apps drain battery.. also, wifi is a big factor in your battery drain since the phone is forced to look for connection.
I hope this helps
Wiping stats is a myth that Google engineers have dispelled a long time ago.
It won't help you at all
Use BetterBatteryStats to see which app is causing it. If you are on Siyahkernel (highly recommended) then tick "exclusive wakelock" to get more accurate ioformations.
Tip: the app is available for free here on xda

Hey!
I´m running Omega on my S3 and I love it but since I first installed it I´ve been having problems with the battery, it seem like it is just getting worse and worse.
I think I am getting 1/3 of what I got with the stock ROM.
Any ideas?
Before i have the omega rom and i have the same problem
i have install the Android Evolution HD and it's very better !!
Problem , Android Evolution HD is a simply rom like the original rom, but you have mods ^^
I have exactly samr situation as above poster, Omega and Android Revolution HD.
But I figure, at least to me, it is possible due to 2G/3G network connection
Sent from my GT-I9300 using xda premium
I've been using Omega for quite some time now and I've tried many settings to maximize battery life like shutting off radio signals, disabling fast dormancy, even using a darker wallpaper to save that extra bit of juice...but i must say this rom just finds a way of sucking all the battery out some way or the other.
I might try Android Revolution now hmm
Thanks guys!
First I thought it was something wrong on the hardware side but now I am sure it´s the ROM.
It´s a shame because I really like some of the features and aside from eating battery fast it also freezes, stops and turns into a brick for a minute or two sometimes. My beloved SGS III is no longer very reliable but I thought those were the consequences of starting to play with the ROM, this is my first time I do something to my Android phone. I´ve been jailbreaking and trying different things on iPhones but never on Android.
Seems like the only solution is to try a different ROM.

UPDATE:
I found the solution and now I have better battery life than ever before
I charged the phone fully and let it stay with the green LED on for about two hours to make sure it's fully charged then I simply put the phone into CWM recovery mode and then Advanced > Wipe Battery Stats.
Thanks.

Yes, everytime after flashing a new ROM, you got to do this and give it a few days for the newly flashed ROM to settle down to be able to measure battery life better.

If I understand correctly, wipe battery stats only remove battery statistics, it does not improve battery life. See:
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
Maybe check the Battery usage in Setting.
I get 48 hours on a single charge through configurations on Perseus. I opened up a thread to detail the config.
