Anyone else have this problem, where the phone will automatically shut off. When it does that, I enter bootloader, and it says battery is low, did a battery wipe in recovery, onto to see the battery, which was at 40%, now at 2%... Any reason why it's giving such a discrepancy....
Running Energy Rom with stock kernel.
Download "Battery Calibration" from market. https://play.google.com/store/apps/details?id=com.nema.batterycalibration
Charge your phone until it says 100% and the light turns green. Unplug your phone. Plug it back in until the light turns green again. Open this app and calibrate your battery.
Should fix the issue

That is a nice trick, but won't fix incorrect battery readings.

funny thing, i tried that....
it likes to stick at 60% for like 7 hours, only to drop the ball and then show out of battery after it shuts down....
could always treat it like a laptop battery to calibrate it, Charge it fully, let it go dead and keep the battery dead for at least 6 hours. Charge it up and let it stay charged for several hours before unplugging it.
Or try and take the battery out, hold the power button for a few seconds, reinsert the battery and try again. These things sometimes help on laptops, figured it couldnt hurt here.
My solution is just keep it plugged in pretty much most of the time, and drain it weekly....
I regularly calibrate my battery weekly. Although, the recovery I use displays battery percentage and it's often different (more accurate) then what is displayed on my battery icon.

So I was overclocking my Atrix 4g and benching it using Faux123's 1.45 Ghz kernel. CF Bench caused it to overheat and restart every time so I did the stupid task of putting it in the freezer (Yes the thing on top of a Refrigerator). And I didn't just put it in the freezer I put it near the part where the fan blows in the cold air. Apparently that wasn't a good idea since my phone suddenly Jumped from 60% battery to 19%. Basically loosing 40% of its charge. Followed by a FC and Reboot.
That night I wen't to sleep and plugged it into an AC charger, it was charging for about 12+ hours. And now my phone won't charge over 60% (Kind of makes sense with the 40% battery loss) and wont go past 1109 mAh ( it's a 1930 mAh battery).
My question is: Have I ****ed up 40% of my battery forever or this something that can be fixed. Note: I have already tried wiping the battery stats.
Try to take out your battery and plug your phone into a wall charger, after that place your battery back into your phone and let it charge

Thanks for the reply.
Should I wait until it has drained or not?
Shouldn't make a difference

If that doesn't work, try recalibrating the battery...

I was wondering if my phone is bricked. I installed Cyanogenmod nightly 17 after using all the previous nightlies without any mishaps, and it drained my battery to 0% and my phone died. Now when I am plugging it in to try and charge it, the phone won't turn on anymore. I have left it in the charger for about 2 hours already, and still no luck with with powering on the phone.
I have tried to make it to go into download mode by pressing the power and the up + down buttons. Nothing
I also tried doing that without the battery. It would just flash the screen then turn off then flash the screen again in a cycle.
Can someone please point me in the right direction on how to boot my phone up again.
Let it charge overnight and hope for the best.
It'd be very unlikely it's bricked. Possible, but unlikely. A number of not likely things would need to take place all around the same time.

So you would suggest leaving the battery in and charge overnight? because right now if I am doing that, the phone heats up
Some have reported it getting pretty hot while charging. Not that common, but does happen. Some have left the battery case off and pointed a fan at it.
You can also plug it into a computer. Usb ports charge at a lower power and shouldn't cause as much of a heat up.
Just make sure it doesn't get too hot. The phone likely won't get damaged but the battery can die at temperatures over 50 degrees celcius.

Take battery out and place it in freezer to cool off, phone too. Take out the freezer and put battery back in. Reboot. Should come right back on.

No problem. Your phone just over heated while shutting down. Happened to me before.

Hey guys I'm getting some really slow battery charge over here. I've had my phone plugged in the OEM ac charger for over 3h now and it went from 5% to 50% and the phone is getting hot also. I haven't touched it at all for those 3h and data is off so no internet. I don't get it. It's usually fairly quick maybe 1 to 100 for about 2h.
Edit: I'm running capcomalpha with fraux kernel and stock battery.

The following suggestion may be of no help in your case, but I've experienced something like this as well, mainly with CWM that doesn't support off-charging. The phone will look like its charging but is actually drawing just enough energy to keep the phone alive. Also, the charging light will turn off after 15 mins or so. One way to ensure that your phone is getting charged adequately is to check the screen; if you see an ultra-dim screenshot of CWM then you'll have to periodically remove the charger and reinsert it "restart" the charge. Then try to boot into android to complete the charge.
The phone is on I rebooted it and it jumped from 55% to 68%

buy a new battery and wall charger so you can charge the battery outside the phone.

You bumped a thread that was still on the first page after only 7 1/2 hours? Please don't do that again, not that I agree with bumping threads, but it is for when something needs brought back to the first page, not while it is on the first page.
do your have a case on? the trapped heat is cause the phone to slow down charging. it is a safety feature. off the case and flip over when charging. it should charge faster.

The phone has no case and was on the table so i guess there was nothing to make it overheat. Sorry for the bad bump i guess i was just desperate.

What version of Recovery are you on and as you said your using faux kernel. Try to revert to stock recovery or stock kernel and see if there is a change or behavior of your phone. And try aand see if fastboot is check on your power under settings..
you said it was hot. maybe you have some app in background using cpu. hence power drain and overheating.

Ok i swithed to stock kernel and its doing the same thing. I reflashed the rom and didnt install any apps to see if thats the case. I also noticed ita doing it only when the battery is low- 10% or less. Then the phone heats up and its barely charging. If its above 50% it charges fairly quckly and doesnt heat up. Ill see how stock kernel does tonight and report back.

Calibrate your battery....cwm, wipe battery stats, reboot, drain battery to the point where your phone won't turn on, charge whilst phone is off, when your phone says its fully charged, remove charger and plug back in to make sure, power on, drain battery again and repeat the process from charging with the device off.
Do that around 4 times. And then maintain your battery by not charging everyday, run your battery completely dead around twice a week. Turn wifi/data off when not using it, auto brightness, bluetooth off, minimize the use of widgets and lwp

Thanks for being so informative. I will do all of that. Is there a chance my phone will screw it self by re calibrating via cmw?
Also I trust your word about draining the battery twice a week, but I'm also curious as to why I've read in some places that you shouldn't let your batt drop below 10%. Is there a specific reason or is it just a false piece of information ?

Reset the stats does no harm . Drain twice a week is pure bull****.

Hi.
I used Battery Calibration from google play exactly as instructed. Since then, my battery is charging REALLY slow, or not at all. When I use my fully charged galaxy after its charged overnight(connected to a charger) it shows 100%, and when I disconnect it, the battery drops... To lets say 92%. What can I do to fix this?
Thanks in advance.
Prayer and alcohol.

Charge it till you're sure it's 100%, turn off your phone, take out the battery for a minute, put it back in and turn your phone back on.

It's not possible to 'calibrate' an SGS2 battery.
Do what Donnie suggested, and if that doesn't help, flash a kernel like Siyah which enables you to reset the fuel gauge from ExTweaks/similar app (you can do it from command line as well, if you search the Siyah discussion thread you'll probably find the exact commands).
If neither of those things work, your battery is on the way out. Buy a new one.
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?
