MacBook Air Not Charging iPhone 7

MacBook Air Not Charging iPhone 7

Good evening all,

I have a mid 2013 MacBook air, and I have an issue which has occurred for about a year, but has only recently become a big major issue, to make me post on here.

When I plug the USB cable into my MacBook (Both Ports), and then plug the lightning cable into my iPhone 7+, the iPhone flashes between charging and uncharging, perhaps each second... Another way to put it is, that the iPhone is vibrating every second, because it is constantly charging, and then not charging.

I have already tried 3 different cables, PRM reset, ending USBD process, SRM reset, 3 different devices (iPad Pro, and 2 iPhone 7+), and blowing the cables, and the USB Ports, to free any trapped dirt / lint.

Any help which I can do at home would be appreciated, I really don't want to have to go to Birmingham again anytime soon 😉

George

The computer's USB ports can't supply enough power to charge the phone. That's why you were sent a wall-charger for it. Use that to charge the phone.

That has nothing to do with charging. Don't attempt to do syncing, downloading, etc. on a phone the is not properly charged. You want to avoid having the battery die in the midst of something important like an iOS upgrade.

How can I sync my phone / install updates via iTunes if this issue persists? It's affecting it all.

Yes, even if my battery is at 100% the issue persists... It isn't as if it is only when charging, it happens when the phone is plugged in, no matter what operation is being carried out
