When my iPad air 2 is turned off and charging, the green battety icon with a black background does not appear. When I press the home button, the screen does not light up at all, it just stays black. And when I unplug the lightning cable and plug it back in, the apple logo appears and the iPad boots up again. Is it not charging when the iPad is turned off? It appears to charge completely normally when turned on but I would like to be able to charge it when it is turned off. I would appreciate some help please. Thank you in advance
This is the normal behaviour, my ipad does exactly the same. There is no advantage in powering it off completely.
I never switch it off but simply close the cover and send it to sleep
