iPad Pro battery shows 100%, But doesn't stay on unless plugged in
As the title says, I had a customer bring in an iPad Pro 12.9 that will not stay on unless plugged into a charger. When it is disconected, it will power down within seconds, and all it will display is a dead battery and lightning cable. As soon as the iPad is plugged into a power source, it powers right up and displays the battery is at 100%.
I have ordered a new battery for the iPad, but I have a couple questions. Is it possible to test the new battery in the iPad without tearing the entire thing apart to see if a new battery fixes it, and if not, what are the chances this is a bad battery or a bad board? Is it worth the trouble of tearing the entire device apart and put it all back together just to find out the new battery does the same thing?
