I just rooted and flashed GummyJar the other day. I have rest battery stats in CW. I am getting very poor battery life. For instance I just went from 100 to 94% in 27 minutes with really no usage. The screen is off.
I am running SetCPU since I was have bootloop issues when changing voltage settings in Gummy Settings. In there when I reduced down to 800 or so, my phone shut off and rebooted into a loop.
So with SetCPU, I have UV to 920 max and 350 min and scaling with InteractiveX. I did not change the voltage settings (still at defaults).
What else can I do? Do I need to flash a different kernel?
BTW, my battery life when unrooted was much better.
I have read you can 'calibrate' the battery by running empty and charging full a few times. I have not tried this yet.
