My iPad works fine until I charge it to 100%. When it gets to 100% it will take days for it to turn back on. I’ve tried different sockets, plugs and I’ve tried hard resetting it. Sometimes it will turn back on after a few days but now it’s not coming back on.
I’m curious…when it eventually does turn back on, is the battery still at 100% or has it lost some charge? I have not seen this problem and other than the battery or a logic board issue, I can’t imagine what could cause this. Next time the iPad is functional, try testing the battery health with a tool like coconutBattery (Mac) or 3uTools (Windows). If it is anywhere below 60%, you should change your battery. If a new battery doesn’t help, then it is probably an issue with the logic board.
I have the exact same issue with my daughter’s iPad. The device shows 100% power once we can get it to boot. Once running it can shutdown anytime then take 1 to 5 days to restart. I just bought a battery replacement kit from Ebay and will let you know if this fixed the issue. I know this post/question is from 2 years ago but I just wanted to update other people on what may fix or not the issue. Thanks
