I own an unlocked Galaxy Tab 2 GT-P3100 running CM11 Android 4.4.2 unofficial.
Today, the battery Was at 90% and after a minute, 7% and when I unplugged the charger 0%. Shut Down!
The screen that shows battery when turned off showed 100% after 5 minutes. But when I turned it on, it was showing 5%. Just after 15 minutes, It showed 100%.
I want to revert back to official firmware 4.2.2 and I am scared that battery may go out while flashing.
Thanks in advance! :good:

Try to fully charge the battery and wipe battstat
Sent from my Desire HD using XDA App
will do, but also it show the battery to be a certain % off charge, but when i plug it in it jumps up to a much higher number?
i flashed to in paris v5 and still same thing
If wiping the batterystats did not help and after using google (yes do that atleast for half an hour) you find no other explanation, your battery might be malfunctioning.
In the later case i would advice against charging the tab unattended.
Hi,
I have recently tried out a few ROMs with my Nexus S to try to get better battery life. I tried CodeName Android and then figured I would try Slim ICS afterwards. I completely wiped everything and installed Slim ICS.
I have observed the following:
- Battery was ~40% when I installed Slim ICS
- I used it until the battery depleted
- Plugged phone into the wall charger
- Started the phone shortly afterwards (~25 minutes) and it says battery is 100% and then the phone randomly shut off
- Phone has been plugged into the wall charger and when I try to start it now sometimes it boots completely and then shuts off. Other times it just shuts off before it finishes booting up. The few times it does fully boot up, it says the battery is 100%
I've read through many postings about calibration but at this point I am not even able to fully turn on the phone even when its plugged into the wall.
Is this expected or is something else going on? I've never seen anything like this when I had the stock ICS. Why would erroneously report 100% but then not even let me fully turn on the phone? Thanks!

Maybe a bad battery?
Sent from my Nexus S 4G using Xparent Cyan Tapatalk 2
Battery is fine. I ended up letting it charge a few hours and it now fully boots up and battery is almost fully charged now.
Whats strange is at times, when the battery was close to empty, when turned off and plugged into the wall, it showed the battery as being completely charged so I don't think it was charging. I had never observed this behavior with the stock ICS.

If it happens again I would suggest taking it to a sprint repair
Sent from my Nexus S 4G using Xparent Cyan Tapatalk 2
same problem
Even I have faced the same problem whenever I reboot keeping my pfone charging,
This is very normal,
just let the battery drain completely and next time charge it till 100% it will work perfectly,
It happens with me whenever I install new rom.
basically the battery indicator shows incorrect status also battery will drain very quickly later but once you finish installation just let your phone charge for 3 hours . Problem will get solved

Also, you could try clearing the battery stats in clockwork mod recovery

Thanks. So it sounds like its more of a generic issue with ROMS in general as I never observed this before putting on a custom ROM.
Recently I've updated my Note through OTA to 4.1.2.
I've spot that after update the Note is just draining the battery.
I could read about 10 hours on it before, and now it is only about 6 !!!!!
I even do not mention gaming, which is draining the battery in 2.5-3h from 100% to about 5%. I could play approx. 5-6 hours before.
It's ridicules.
Did any of you spot the same thing?
I haven't installed any additional apps after update that may "help" to discharge the battery.
The values above are based on Screen usage time in Battery menu.
Any suggestions?
After the update, I'm facing recharging issues. The tab is taking twice the time of what it used too to recharge to 100%.
i haven't spot any issues with charging.
.
Same here.Used to get 10 hours of screen on time,now i am lucky if i get 8 hours!

Same here...
Some tips :
Kill all apps, switch to offline/airplane, and power saving mode when charging..
Still not working?
Try reboot your device once or twice if necessary..
And your device will charge normally
Work on my gnote...
I hope it will work for you too
Correct me if i'm wrong
Im using juice defender with good results, I lost a pretty noticeable amount of battery time after 4.1.2, too.
Maybe a problem with the battery stats?
Try to drain the battery empty and full charge afterwards.

It will damage the lithium battery when you drain it till empty
I think it is Wi-Fi that drains the battery !!!!
Usually I was leaving the tablet with wi-fi on all the time. After 4.1.2 update it takes approx 2% of battery per hour !!!!!!!!!! when you do not use the tablet but wi-fi is on, so after night in the drawer you had approx 10-15% drained.
When I turned the wi-fi off and left it overnight i haven't loose even a 1% during the night !!!!!
I have to try to work on it as usual but with wi-fi turned off, it will be difficult though as usually i play on-line or browsing the net
I think they f#^%*d something in 4.1.2 update with wi-fi energy consumption. hope they will repair it in next update.

I mean, just let the device turn off by itself, and after that, charge 100%.

Yeah, I had this problem after I updated too. It was also laggy. I did a factory erase and now it works better. I think it is still draining more than before, but not as bad as after I updated. I think a good rule of thumb is to wipe everything after an update and start all over. You could also try wiping and flashing the rom for a fresh install.
I suggest you to change your rom to germany stock 4.1.2...
It will solve your charging problem
Tested on my gnote
Help guys! I have weird problem...

Android has several problems when detecting battery charge. Resetting the battery stats in your recovery will help.

Phone: Samsung Galaxy SII GT-I9100
ROM: XenonHD v10
I have been using Samsung Galaxy Grand (I9082) since over a year and now the phone switches off randomly (generally at 28% of battery remaining) and when i try to restart manually, it does not starts (and battery drops to 1 % ) until i plug in charger and within 2 minutes battery shows more than 30% charged . I have been charging the mobile from some other nokia charger. The battery graph also shows red lines. Does this indicated the battery problem or phone.
NOTE : I have done cache cleaning with fresh Android install after the problem started in order to trying to fix the problem. Below is the battery graph.
Have you installed any custom firmware?

I installed firmware, because the latest official updates lagged too much. So I went back to the the previous official firmware upgrade.
