I barely push 8 hours (maybe 2 hours of on screen time) with the OEM battery, and maybe 15 hours (4 hours on screen time) with a 6400mah Anker battery. I keep seeing the Android OS usage is ridiculously high, but I can't seem to source it. I installed better battery stats, and
"NFC test" seems to be causing some issues with wake locks, but that seems like a core application. Is there some other reason that this might be the cause for such high system usage? I really don't want to re-flash and lose all my app data.

My phone also gets really hot whenever I play Plants vs Zombies, but that's probably unrelated
