You will not have any problems charging from that port. It seems more to do with data. Since this post, I've switched my phone to the port in the dash, and keep a dashcam plugged into the center port. It runs fine. No issues with my phone in the dash USB. Do not want to go to the dealer for service, they don't seem to be the greatest and I don't want it getting worse.No clue. I keep a USB chargeable LED flashlight plugged into it. So far, it stays charged.. ha ha!
