I recently updated my iPad Air 2 to iOS 12.1 only to find that it would no longer charge via my computer’s USB 3.0 port. Specifically, I had been using, for many months, a decent quality aftermarket cable to connect/charge the iPad to my PC. There were no issues with charging or connectivity using the same configuration prior to the iOS 12.1 update.

A bit of digging suggested a two-part solution:

• Power off and restart the iPad
• Use a genuine Apple cable

Well, powering off and restarting (using the same aftermarket cable) did not work; the iPad still would not charge. However either changing to a genuine Apple cable or a different aftermarket cable together with a power off and restart, did work. The iPad is now charging normally from the USB 3.0 port on my PC. The parameters are 4.71vdc and 1.71A at the USB port.

I am not sure what Apple did with the iOS 12.1 update, but this problem seems to be fairly common.

Thanks for reading.
