None of this is doing anything. That pesky Android System and Kernel usage still takes a good 20% of my battery. My mother's One is entirely neglected, and hasn't been updated to Kit Kat yet. It loses only about 1.1% an hour on standby with location services and auto sync and mobile data on. My phone on the other hand loses around 3.5% even if I don't touch it!
This happened on stock, it happened on CM11, and it's happening on VenomOne. This leads me to believe that this is a problem with Kit Kat. Is CM 10.2 a viable option for me? Is it a stable ROM?
