Answer to: I see a charging symbol, but the battery percentage is not increasing.Hello, I have an iPhone 6 and struggled with this all night last night. Just wanted to share my solution- the charger and wall plugin that I received FROM Apple is apparently defective. Right before this started to happen I got a 'this device may not be supported blah blah blah'. It charges it but very, very slowly. Just to give you guys an idea of how slow, it took over an hour to get it from dead to 1%. Just as a side note, the cord and wall plugin I received FROM APPLE have no cosmetic wear or tear on them (outside covering it not ripped, no exposed wires, etc.) so I am assuming it's something inside the cord that is causing the issue? Just thought I would share as I tried everything before I was able to get my hands on a new charger but nothing worked. So frustrating!! Good luck to everyone else!! Hopefully it is something as simple and cheap as replacing the cord!
