Make sure there’s no lint and dust compacted in the bottom of the port if you haven’t already. It isn’t always entirely obvious but it can affect both lightning and USB-C and you can usually get it out with some careful use of a sewing needle.

My oven has capacitive touch buttons for the clock and timer. They’re really sensitive, and they sometimes trigger even for skin underneath clothing. So sometines when I lean against it while using the stove top, I accidentally set a timer with my penis.
