Hi, Even after replacing the battery in my iPad Air 2 it seems to drain quickly. I have been advised that maybe one of the pins on the battery is not making a connection and therefore not all battery cells are not in use. Is this even possible since it works and charges as normal? Is it more likely a poor quality battery? Thanks, Stephen.
You can get a new battery from ifixit for 45 dollars and it comes with tools and everything to put it back together.
As you said “maybe one of the pins on the battery is not making a connection “ i think that’s not right, If that happened then your mobile would not be ON and it would not be OPEN.
