My iPad is connected to charger yet battery level decreases (not as fast as plugged off but still).
Is it a fault that can be directed to Apple Support for warranty or normal behaviour? I though that charging by cable and using device means power is taken directly from grid while battery loads.
PS It's charged by iPhone plug. iPad plug is bigger and I am in trip so took smaller one. Those end plugs give different charging capabilities? Is it safe to actually swap them like that?
