Same - I have an old simless phone that I use for banking and other sensitive apps. It only charges when the cable is just so.

Socket wear is definitely a design failure. Hoping it holds up until I end up replacing my current leaves-the-house phone.

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.)
