回复： iPhone says "This accessory may not be supported"I have changed my charging port twice. Tried a lot of different cables. I finally discovered,If I leave my phone laying for about 20 minuets, plug in the charger and it charges. Either that or charge it with the phone turned off. Its a pain in the ___ but my Iphone 6 is 9 months old (Refurbished). Update (09/21/2016): I replaced my logic board with one from a different phone just to prove its the u2 chip. Then but the original one back now everything works great. Did something need to be reset? Was there a bad connection somewhere? I'm not sure why. But I'm just glad to have my phone back.
