I have been having some troubles with my lightning cables recently from both Anker and the official Apple cables. I am having an issue of the cable going into the device and not making good contact with the device. I have previously had an issue where the cable wasn’t fitting in just right and cleaning out the lightning port fixed it, but now it seems to be the cables themselves. You can see debris building up on the contacts on the cable ends. I have heard of people soaking the ends in vinegar previously and then letting it dry before using it. I originally was only having this issue with the cables in my cars, but seems to have become an epidemic over the last few weeks. If I swap the cable out for a clean one, it works just fine.
Any suggestions?
