Hi - hoping someone can help me here. I'm using the charger that came with my iPhone 6 - it charges fine, but whenever it gets to around 100% (sometimes around 95%) I get the error message "This accessory may not be supported" and it the lighting bolt over the battery turns off. I tried using the phone for 10-15 minutes online while plugged in and even though the charge icon wasn't over the battery, it didn't drop any percentage, but I've gotten this message after every charge. If I unplug, and re-plug back in, it comes back over after a few minutes if the battery level is between 95-100. I tried using my wife's iPhone 5C charge block and got the same message. Anyone else?
