Iphone Not Charging When Plugged Into Mac. Charging the device also appears impossible since the iPhone keeps charging and discharging when connected to the Mac. If the charging port is damaged your device probably needs service.

Here is the solution. Let your device charge for half an hour. IPhone stops charging when I connect to MacWindows.
Now the phone is not coming back up at all -- it has been stuck on the Apple screen for about 10 minutes now.
Check charger and cable. You wont hear the characteristic ding or see any indication that charging has commenced. If you see your iPhone iPad or iPod under USB Device Tree get the latest macOS or install the latest updates. IPhone 8 or later and iPhone SE 2nd.
