I can pretty much guarantee that it’s not socket wear, but a buildup of lint/dust etc. I’ve got an original iPhone 5s whose lighting port still works perfectly. Needs to be cleaned out every now and then, but it’s durable as balls.

Thanks, but that's simply not the case.

The socket is clean, lint was the first thing I checked when it started happening. The uneven wear on the socket sheath is clearly visible under a magnifier. (This is a 6S.)
