I've noticed some very significant battery drainage lately. I'd start the day off at 100% and two hours or three hours later at work, with only a few game plays and a Facebook check or two, I'd be at 71-74%!!! I noticed that my purple "Active" location services symbol was on often. I went through Notifications and discovered that Reminders is actively using GPS on a very regular basis. I think this is because I set a Reminder based on "When I return to XXX Location." so it was seeking GPS often. Anyone else notice this?
