iPhone 6 will not charge with certain chargers
I have an iPhone 6 that's being very picky with chargers. I have one OEM Apple lightning connector that charges the phone fine. However, it refuses to charge when connected to anything not OEM. We've tried 3 aftermarket chargers and the phone will not even show the red battery on the screen. The port on the iPhone 6 port is cleaned and free from lint and debris. The same aftermarket chargers work fine on my 7 Plus so the chargers are not broken. Any ideas why it would have this issue?
