Hello Guys,
As i wrote in title, here is my problem.
After work i put my phone in the pocket with 60% battery, after 15 minutes i tried to unlock the phone but i saw that the phone was shutdown. And when i power on again i saw the battery was at 30%. I took some screen shots of battery usage screen.

If you noticed i took first image at 21:15 and the battery was at 35%. The second image was captured at 21:37 and the battery was at 37%. This is not logical
Any suggestions?
Thanks a lot
Calibrate your battery
Sent from my GT-I9100 using XDA
The only way to calibrate a sgs2 battery is....... time.
The fuel gauge chip well recalibrate itself by just using it.
1. Just charge uninterrupted to approx 4201mV (this can be sometime after after reaching reported 100 full).
2. Discharge to near 1%
3. Charge (uninterrupted) again to max mV
4. Unplug & use normally
Note. Deleting battery stats does nothing on the sgs2

jus remove the batt,press power button 2,3 times so all power is out and totally switch off and charge and wen shown fullgd dont take charger out wait 2,3mins and on the phone wiv charger plugd on ,wen the phone starts it will show charging again ,,let it charge...see my phone gives a sexy life sometimes but sometimes it dosnt......so bottum line is "yes android is power hungry"
Thanks a lot, i will try this solutions.

Hello guys, I'm trying to figure our how much my battery can last on one charge, but I'm having a problem in the
Settings> battery,
Where it is supposed to show the usage.
Every time I charge the phone and plug it out, the graph doesn't reset back to 0 hours and just keeps on adding on the total time the phone is on. You can see in the graph the battery percentage keeps going up and down, I can't get it to reset on every time I unplug it from the charger, even by pressing refresh.
Is this a bug for me or is there a proper way to do it?

Hard to evaluate first part because only you know how intensive you use it. However, the bolded part concerns me. Could be a dud? Mine definitely gets warm especially here (check my location) but not hot by any means. Btw, do you have Infrared Thermometer by any chance?
Battery report only resets when your battery reach 90%+ and you unplug it
For some couple of days am facing this problem, thought that my phone wasnt charging properly nor reading perfect charge. Downloaded the V6 calibrator and now am more confused about which one is showing me the right info Can anybody shed some light over the matter Will be a great help. Thanks in advance
Please, see the screenshots below as the battery is showing 10% but reading 30% then with V6 Calibrator its saying that the battery should read 53% confusing!!..

It's not reading wrong.
The script requires your battery to be 53% or more. So you will need to charge it and then retry.

Thanks and the script also asks for the battery to be charged at 4200mV & 20minutes more, before it could start the calibration, which unfortunately, the battery never gets to! always ends up somewhere in 4100mV or just a bit more than that. It once reached to 4192mV then started loosing power rapidly. Never actually reaches to 4200mV. What should i do about that? By the way, all the time when i tried the script, i made sure that the phone is on airplane mode so nothing can work behind
Those 4200mV is a general expression and not specific for the Xperia S, just charge to full and you cant do any mistakes.
People usually talk about battery life for continuous usage, but i want to ask about battery life when leaving the phone off ?
After a few tweaks, i noted that betterbatterystats shows my phones has been booted on for 5 days 15 minutes, out of which it's been 4 days 5 hours 20 minutes in deep sleep; and only seen 1 hour 59 minutes of actual usage (screen on basically means when i'm actually actively using it)
unplug means when i unplug it from usb charging after it was already 100% fully charged.

So how does my phone battery stats compare to the normal life time for the Samsung S3 when not in use ? just wondering.
I give most credit to greenify for helping keep my phone in deep sleep mode most of the time. Apps that are waking my phone is mostly googlemaps, and greenpower (left this ungreenified because it managed when to turn on/off my wifi, when i open screen .... which it probably can't do if i greenify it)
other than the few wake locks; the wifi on is mostly due to syncs. I usually set my apps to at most only sync when i turn on the app, or at max once a day. Greenpower will trigger to turn on wifi when the app requests access :X
PS: i'm using wanamlite and adam kernel. As well as philz CWM touch for root.
Recently i found in your forum one code about the battery.It's show battery status.

Seems not to work on my i9300 with cyanogenmod.
There is just nothing happening...
David.
nothing happening on stock either.all I'm seeing is when quick start is touched the screen goes black and when power is pressed i am at the lockscreen. swipe and go back to the battery stats. no idea what it does other than turn off screen
after reading this thread http://forum.xda-developers.com/showthread.php?p=30512141 apparently quick start somehow recalibrates the battery as many have reported either a large increase or decrease in the percentage.
I was reading ur thread and dialed this code.. i pressed quick start and boom screen was off.. when i again turn it on my battery level was dropped to 19% from 65%
I plugged in charger and repeated the same thing it goes again to 65%
Once more after pressing quick start and this time not charging again it dropped to 35% i re do it and now i am on 65%
I am on stock rom with no battery issues.. if any thing happens to me i am gonna sue u lol... any one please tell me what is this and what has happened to me ... i dont wanna get any battery problems
May be it is for use in emergency..
And i am already in that mode with higher percentage allowed
I am going to restart mt device now .. i am worried now
"quick start" is for setting the battery gauge. It loads the cpu and then resamples the battery. What I wish to know is what files or nvram items it changes.
Hello there, I'm new to the Galaxy S2 forums, I before had an Xperia Arc.
I have a problem that happened just last night. Last night I turned off my phone and left it, didn't touch it. That was about.. around 1 am, right now, 10am I woke up and turned it on. Samsung logo, ROM boots etc, I check the battery and I have 8% left. What??
I took these screenshots, Wakelock Detector screenshots would be useless as it only shows stats from when I turned it on, and everything's normal.

As you see it lost that huge amount of battery while turned off for no actual reason.
I'm not sure it's an "overnight" issue, I've noticed a random and huge battery drain on power off/on (even on reboots) on 3 different Samsung devices, using different kernels and roms.
[EDIT] Sometimes the battery even slowly recharges by itself with time, so maybe it's a battery stats-related issue [/EDIT]

Well yes you're right too, any idea of why this on/off huge battery drain?
Use battery stats plus..
And check what is causing battery tp drain
Difference in battery level after reboot is quiet normal thanks to the fuel gauze chip we have
