Device not charging when off, but charges when completely off
So my iPad Air doesn’t charge at all when it’s on, and when I plug it into my computer, it shows the USB not recognized or malfunctioned. I’ve tried it on another computer, used different genuine lightning cables, same result.
However, when shutting off the iPad, it apparently starts to charge (according to the readings (Volts and Amps) on the Battery Activation board. I have updated it to the latest iOS but nothing has changed. So to summarize, it does not charge when the iPad is on, but does charge when completely off. What would be the problem in this instance? Thanks!
