fix rhe charging port on an iphone12

If you have tried other cables and other chargers to confirm that it is the port on the iPhone, unfortunately Apple does not "fix" the port unless it is something simple like removing lint, dust, etc.

If the port is defective, Apple will suggest a replacement phone. That could be quite expensive.

In that case, it might we worthwhile to check out a local shop that might be able to repair or replace the port. Worked for me on my wife's iPad, but no guarantees of course.
