iPad showing same usage time.
My iPad shows the exact same times for usage and standby, even though it is asleep for most of that time. Up until two recharges ago the time reflected correctly, with differences in usage and standby. Also now it is losing about 8% battery overnight while in sleep. Bluetooth is off, Cellular is off. For the first 6 to 8 weeks it might drop 1% or 2% overnight. Are there reasons for why this has started happening?
