iMac is not charging my iPhone
My iMac is not charging the iPhone it continuously beeps on and off. I tried support the other day they had me reset the phone and the issue did not resolve. Further the incident number provided isn't recognized so I can't get back to them. I believe it is an issue with the iMac over the devices. My iPad and work iPad do the same things. They won't charge steadily if its under 60%. They go charge...uncharge...charge....uncharge.... and so on both devices are using Apple cords. I have tried all ports flipped the cords upside down. Used the NES trick and blew the inside of the plug port.
Any other solutions? Anyone else have this issue?
If iTunes doesn't recognize your iPhone, iPad, or iPod - Apple Support
I used this site ^ but it didn't offer enough of a solution. iTunes does recognizes it in intervals as it connects and disconnects.
