Replaced battery that customer thought battery was dying and iPad mini was fine. I had lock screen with home picture and pin came up so I knew it was good to go. I plugged it in and went to bed. Next day I went to check it so I could deliver it and it had not charged at all. I can plug it in (with OEM cable and block) and I get the flashing low battery and lightning symbol but it never charges. Thoughts?
try to clean the dock connector with some IPA spray because it’s fake charging now , it shows that it’s charging but doesn’t take no power . If it’s still not working you will need to replace this sparepart , but you will need some soldering skills :) iPad mini 2 & mini 3 Lightning Connector
