Me thinks not so.I think you have a USB Problem.
I have now tested USB charging with another iPad Air 2 on the same as well as different USB port I used for the other one.
This iPad charges, at what I perceive, at a normal rate, up to approximately 75% battery
capacity. This is when Sierra is awake. From 75%, give and take a few %ages the charge rate reduces considerably, however it keeps on charging. When I then force Sierra to sleep, the charge rate picks up again, and quite noticeably too.
I will however continue testing to ascertain what is cooking. I am hesitant though, to start chasing a problem which may in the end not be a problem. My iPhone on the other hand charges from 20% to 100%, at a constant steady rate.This to me is understandable as it's
charging current requirement is half that of an iPad.
