HD+ battery drained 40% overnight

lmacmil · Jul 6, 2014

My wife's Nook running 10.2.1 went from about 55% to 14% charge overnight last night. It was in sleep mode and WiFi was off. Normally it would lose 2-3% in that length of time. Usage was mostly Google Play services and Android OS. What would Play Services be doing while the tablet was asleep?

Play Auto updating? Just a thought. Most of the time I've found excessive battery drain attributable to some app's hidden agenda.

WiFi is off (supposedly) when it's sleeping so that shouldn't be happening. Even so, I wouldn't expect apps auto-updating to take the battery down 40%.

Possibly an app goin crazy during a wakelock, which allows an app to do stuff while the phone is asleep.http://manojprasaddevelopers.blogspot.com/2012/02/what-is-wakelock.html

There are sleep related bugs sometimes as well in the roms, but since its been out a long time now, probably isn't that.

Not sure what else.
