I'm not sure if others have had this problem, but I updated to 4.4 a while back. I've never ever had problems with battery life on my phone. It lasts about a day comfortably. However, I decided to see if I could get better battery life out of it today by enabling "battery saver", as I haven't really ever noticed a degraded performance by doing so on any of my phones. Upon doing so, I flipped the switch and scrolled away to find that it immediately kicked off. I've cleared my cache and am running with dalvik runtime for stability. Has anyone else encountered an issue, or possibly a solution? I'm avoiding a factory data reset, as I'd rather deal with the problem than have to start over fresh.
