M I have disabled all location service , disabled background APP refresh, disable airdrop. Disabled icloud. Turned off find my iPad, turned off bluetooth. And the battery still dies as minute goes by. I locked the screen (standby mode) and even with that, the battery drops 1% every 3 minutes. This is a lot worse than my iPad 2. They have pretty much the same content (copied from iPAD 2 except that I opt not to upgrade to ios 7 on iPAD2). If I leave both iPads fully charged but unconnected to the charger, air will die over night, while iPad 2 will still have over 90% battery left. Is there anyway I can test whether I get a defect battery with the air? Thanks!
