I have my EVO rooted and for some reason my battery just doesn't last very long is there a way to fix that i have read that flashing certain kernels could help is that true?
p.s i have read other threads about battery life but none about kernels that can help
I would nuke bloatware. There's a sticky on the topic in this forum. You can ignore the part about using temp root since you're rooted.
Here's something I posted a few weeks ago on SetCPU, a quick search woulda resulted in this..
Here you go:
Priority 80 - Charging - CPU is max 998
Priority 70 - Screen off - CPU is min and max 256
Priority 60 - < 40% battery, CPU is max 768
Priority 50 - < 20% battery, CPU max is 576
something like that. everything is ondemand.
