Last night I charged my battery to 100%, then took it off the cord and set it aside. 12 hours later, I unlocked the iPad to find the battery had drained to 85%. Push and Fetch have been turned off, so have location services and the iPad is not jail broken. I hope you all can tell if such a drop of charge is at all normal. And if not, can the Apple Store tell if my battery is defective? It's a wifi only model by the way. P.S. The battery dropped 2% just while typing this out.
