Yeah, surveying my friends I found one other person with this problem, but it isn't the majority case.

It doesn't seem to be a problem with the cable, it's really a problem with the connector on the iPhone itself. All my iPads charge fine on Lightning cables. I keep my phone for longer than two years, for one. Or maybe there's something specific to my pocket, where the sort of lint that gets into the iPhone is especially degrading to the connector?
