Just the impression from the reply. It is hard to grasp tone from the written word, but that was my impression. Glad I was wrong on that.
Moving on to the whole problem at hand. Again, all of my data has been retrieved using a Meter, and not the display on the phone, but that is all on 2017 Model hubs, which the chipset did change in to meet the Apple CarPlay certification requirements. I would not think that Ford would have changed the Voltage output, but they might have. Seriously, the only way to solve this is for you to use a USB Power meter. For $15 you could have it tomorrow... Since you seem to be a Tech minded person, it will come in useful again.
When you get the Meter, check with your phone, and another phone.
Omar's explanation of "Smart" might also be a good way of explaining the difference.
