Tried posting on Apple.com and for some reason it's not letting me. This site's probably more useful anyway though :-D So far I've had 100% of lightning connector devices fail (never had an issue with the dock connector nor USB). I bought a Smart Battery Case with my iPhone 6s last year, hoping that by having the phone permanently plugged in to the case, it would protect the lightning connection... Off and on I've had issues with it, but they've been solved by rebooting and connecting/disconnecting the case and phone until they both work. Well, it's getting worse now, and the physical connector in the case is turning partially green (despite being physically connected to the phone 100% of the time). Wondering if there's a way to clean it safely or fix it period. Right now my case charges fine if it's plugged in to power by itself (with the phone removed), but the phone's connection-seeing the case, connecting cleanly to my PC, charging from the case, is all hit and miss, even after multiple reboots and re-connections. I've tried cleaning lightning connectors in the past, and while I've gotten them to physically look okay, they NEVER work again. (Had many cables fail in the past too as far as that goes.) Really wish Apple would switch to USB... Not the greatest picture of it, but you can sort of see what the physical connector looks like. (Which may or may not even have anything to do with the issue.
