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

[Resolved] [Q] Battery / Batstat Issue? Please help.

Hello, my Karbonn A9+ really lacks on battery capacity (1450 mAh) that's why I bought a modded S3 battery (2100 mAh) and it really fit.
Everytime my cellphone shuts down due to low battery. I start to think that its clear that my battery is drained. But once I turn it ON again. The indicator shows around 10-20%. Until it shuts down again. Then I'll turn it ON the second time. Indicator shows around 10-20% again.
Its really annoying cause, I don't even know when will my phone really drain or gets to at least "please recharge your phone" state.
I've tried resetting my battery stats and still have this. I also tried draining my battery to 0 (after multiple times of turning on). and still have this.
Please help me!!!
Thanks in advance!

You charge the phone off least 7-8 hour. After you use phone when battery shows %5 then go to recovery and wipe battery stats and again charge the phone off least 7-8 hour. It will fix. If it won't fix you continue give full charge closed phone 2-3 times :thumbup: sorry bad english

Too bad it didn't work.
Hi peeweew ,
then what is status now?
-
hi, you have tried battery calibrator. it helps on some phones, on mine it didn't work, i also tried to do the cleaning of the battery stats still it didn't work..
the solution which i found was that you try to use a different charger and it will fix. when your phone shuts down plug in the different charger and then wipe the stats.
it worked for me, should work for you..
Press thanks if helped!!!!
I think my battery is now ok. Tried everything you people suggested. Thanks for the help!

Battery won't charge beyond 38%

I've been having this problem for the past 4 days, my Nexus S won't charge beyond 38%. I was due for a battery replacement, I got that today, and even that wouldn't charge beyond 38%, after reaching 38%, it says charged. Please help
A friend of mine had the same issue with his galaxy Nexus.
I am not sure if he did what i him worked. He never said anything to me.
1. Use your phone until it dries out and shut down on its own.
2. Start it up to make sure that it immediately shut downs from the lag of juice.
3. Plug in the phone, when it is off and let it charge to 100% ( do not start the phone until then )
4. Repeat the same proccess once more.
This might help set the battery stats that you have for your old battery that are saved on your droid.
If you are rooted it might help to cleat the battery statistics as well.
I'll try it tonight and post back

Your battery is gone. Order a replacement from shopcules.com

I did get a new battery, still gives the same problem. And for some reason I'm not able to keep the phone off, every time I do that it just switches back on.

Couldn't get the phone to charge in off state, kept switching back on, and reached the same percentage and stopped charging. Also used battery calibrator app to clean the battery stats. :/

Battery problem now at my wits end.

Sorry peeps long story coming.
A few months back my 7.0 galaxy tab 2 wasn't charging I purchased a new cable and that did the trick, fast forward to now and my tab has stopped showing accurate charge lvls it can be on charge for 10 mins and claim 100% or it can be charging overnight and still show 0, so i've changed the battery and it hasn't made a difference I was advised to use kies and refresh the firmware but kies didn't work, so I was then advised to install cynogen mod which I have done in the hopes it would clear the error but same problem occurs just it's always on 0.
The unit Turns on and stays when plugged in so I installed a battery calibration app which I understand erases the battery file.
Again no joy.
I'm really stumped now what's wrong with this tablet.
Any advice on how to fix would be very much appreciated.

Samsung Galaxy S3 wont turn on or charge anymore (please help!)

Hello,
My Galaxy S3 doesn't turn on or charge. Three days ago I left it charging (it had around 20% battery) and after some hours time when I came back to check up on it it wasn't charging and could not be turned on anymore.
I bought a new battery and tried turning it on or charging it with this new battery and nothings happens.
When plugged in the red light doesn't turn on and the classic screen with the green battery doesn't appear
When leaving the power button on, no response is given.
If you could give some advice on what the problem could be and how to fix it...I thought that it could be the charging port but even if this is the case and you have some tips on how to fix it I would appreciate it.
Thanks in advance!
