Battery levels really jumpy
Hello, ever since flashing cm 10.2 on my phone, I've noticed that my battery was being drained extensively by Google services. A full wipe and re-flash later, it was fixed. Well, during those two flashes, my battery level has been erotic.
I can go 4 hours with normal drainage and then the phone casually reboots, and then says I have 9% or so remaining. It will "charge" itself to 13%, reboot again, and it the battery will report that it has around 20% or so, and drain normally.
The battery life has diminished a bit, but that could be because of age, and it barely lasts me 8 hours.
Does anyone know of any solution other than buying a new battery? Recalibrated has helped, but not by much.
As always, any and all help is appreciated.
