Just wondering - I have a new 12.9 2018 iPad Pro. Before I go to sleep, I plug it in to charge and then switch it off (so it’s not turning on because I’ve plugged it in) and put the flap of the cover over (it’s the Otterbox one just released). When I open the flap of the cover in the morning it’s switched on. Anyone know why? My theory is it does this when charging reaches 100%, but that doesn’t seem to make sense. Do others experience this?
