There always seems to be some sort of residue left in the port when I'm finished. It seems tighter when I'm getting it back out too, like the port has closed up a little.
USB-C Solves this problem
I've been relegated to wireless charging for some time now, haven't been near a port in an age.
I put my USB in the wrong port for a laugh once. The computer didn't like it at all and went all BSOD on me.
