[Q] Phone turns off when charged

[Griff43081]

So it seems that my phone won't stay on when fully charged. If i leave it plugged in, once it gets to 100% it will shut itself off. I recently upgraded to CM10.1 nightly and have tried 3 different days. I've also found something about using setCPU, but that didn't seem to help either. Also, i can't turn it back on unless it is unplugged from the wall.

To make things worse, i noticed today that when i turned it back on (it turned itself off over night), it was at only 7% battery life. So now i have no idea what is going on.

Thoughts??

SoD.

There are quite a few things that can trigger it (like deep idle) but first I'd need to know what changes/mods you made.

So i was running CM 7 when decided to finally update to 10.1 nightly. That was major change and it started happening. Last night i downloaded setCPU, and configured that to keep minimum @ 200MHz when screen is off (hoping to keep it running and not going into deep sleep).

Did you go back to stock and factory reset first? Also, did you restore any system app or data with TiBu?

Are you running with stock kernel? If so, you could try flashing Semaphore.

I do not have a stock kernel, but it was the same one from when i was using CM7. I also updated from CM7 to 10.1 (no from stock), but i did do a factory reset. ANd no programs were restored, i freshly installed them all from the play store. I will try flashing Semaphore tonight and see how it goes.

Kernels for GB are quite different than for JB 4.2. When you flashed CM10.1, it most likely also flashed their stock kernel. This is what I meant by stock kernel.

any possibility that you've got a battery that is failing? or if the third pin is dirty, the power management chip could do that, even if the battery isn't fully charged. when the battery was at 7 percent after 'charging', what was the battery level before charging.

have you cleaned the batt terminals on both battery and phone?

hope this is helpful.

To make things even more confusing ... every time i reset the phone it comes up with a new battery level (anywhere from 5 to 17 to 60). new battery time?

Indeed, new battery time!
