My fast charging hasn't been working for awhile either, and my phone is only a few months old. I have to do the same thing that I saw another person on here said they had to do, I have to unplug and plug it in again many times, I have to unplug and replug the USB cord in and out of the charger many times, that is the only way it worka at all. It does not work at all when I unplug and plug in the whole charger, only when I do it with the USB cable. Use to be I only had to so that 3 or 4 times, now I have do that 20-30 times as well, it's getting frustrating and I feel like that is definitely not good for the charger either. I even replaced the USB cable and that only helped for a few weeks and it's now back to the same thing. Any other ideas, or do you think I have to buy a whole new charger? I have read through all the posts and have tried all the ideas on here and nothing. Please help, any other ideas to try wouls be greatly appreciated! It takes so long to charge phone without fast charging ugh, they should have made the charger so it is ONLY fast charging ugh, because who would want to charge it that slowly?!
