My battery drained ~40% overnight and the cuprit looks to be something called "google services". Not sure all this encompasses but here's what I did:Removed "google play music" and "google play video" apps since I never use themSet all apps back to default settings (in effect turning all location services back to off for now)Went into my google account and unchecked all the "sync" options with the exception of calendar, and gmailAnything else anyone can think of? Not sure if this will even correct the issue but I'm optimistic. I have a feeling it was just trying to sync everything on somewhat of a regular basis.
