Battery Issues after screen replacement
I run a small repair business and have recently come into an issue with the I pad air after a screen replacement.
I have repaired a large number of these with out issue but I have had 2 (my personnel one included) that have caused me issues.
I do checks before all repairs and make sure that the devices charge at least 2%.
I always disconnect the battery before LCD removal.
The screen replacement went smooth. All screws returned to the correct spots etc.
I then check functions again before closing up.
Had no problems but a day or 2 later my own personnel I Pad wont charge past 1% and now my clients I pad just shows the red charge battery symbol and wont boot.
I have restored both and put the latest updates on them.
I use an genuine Apple charger 12W and USB cable and use mains/wall power. I have a few lying around and have tried others with no luck.
Any ideas or suggestions?
