Charging cable intermittently not working on some but not all devices
Riddle me this: I have 2 official Apple lightening charging cables plugged into 2 perfectly working sockets. Each have had my iPad and iPhone 11 plugged in at various times - I don’t stick to a certain cable for either device. I go to plug the iPhone into one cable tonight and it just will not charge - wiggle the cable, blow out any potential fluff from the phone etc, nothing works. Plug iPhone into the other cable and it starts charging fine. Also plug iPad into first cable and that also is charging fine. This has happened once or twice before and it always just goes back to working on either device again the next day. I don’t understand what is happening. Any ideas?
iPhone 11, iOS 14
