Recently my Ipad 9 has been having issues with charging. Right now I have it plugged in with the charging unit, and am listening to music and doing a little surfing. The little charging icon shows green with a lightning bolt. But it is holding at 65% and not going any further. I have rebooted and to no avail. Even when I plug in the charger over night, and it is turned off in sleep mode, it still does not advance to 100%. Have sent for another lightning wire hoping that may be the issue. But what if it isn't.
