iPad Pro 12.9 battery replacement, not charging.
I replaced a battery in the iPad Pro 12.9 iOS 11 with two OEM batteries. The charging symbol appears and sticks at 1% or 30%. I put the old battery back in and it charges and functions perfectly.
Not sure what to do at this point. I googled the issue and couldn’t really get a tip.
Any advice?
Is this a good question?
