Battery got worse lately. Not sure what is making it drain so fast. Lately, I get about 2 hours sot. When I got this replacement for my lost s6 a few months ago, I got 4 hours sot. Not sure what app I got since then that may have changed things. Gsam shows Android System ay 9.4%, the highest, then Kernal at 5.2% and System at 3.0% . Do things like twitter in gsam at 0.4% really matter? Seems like such a small % wouldn't matter.
