Hello everyone! I'd like to ask a general question. Currently I am rocking an Air 2 Wifi only with the lates iOS 8.3. I have read tons of threads about charging my iPad at night does not affect my battery however I prefer to keep everything unplugged. I always unplug my iPad at 100% before I go to sleep however when I wake up I see 20-40 minutes of usage regardless of I received notifications. Is this normal? Thanks!
