My version of this iPad stopped being able to charge. I got a new one because repairing it would take too much time (and I wanted the 2018 model).

I gave it to someone else who took it to a store to get repaired.

I had described the issue as being an issue with the lightning port. I said I thought that was the issue because if I wiggled the plug when it was connected, I could sometimes get it to connect and start charging. It would stop when I let go of the pressure I put on the plug.

But now the store has said that that did not fix it. I assume they mean they replaced the port.

So I’m just wondering, what else COULD be the problem? Given the description of how it was behaving.

(Hope that made sense. English is not my native language)
