Hello everyone, I am replacing my iphone 8 battery and damaged the black foil (wireless charging coil?) by accident. Can I still use the iphone with the new battery?

EDIT:

Added insulating tape to the damaged parts of the black foil and unconnected the power of black foil.

Yes, it would work fine without it. If you are too worried, you can add a small piece of tape to cover the lifted film. The battery doesn’t even adhere to that with the pull tabs.
