You mean the micro USB 3.0 v1 which was backwards compatible with micro usb. That’s right you could use the new fangled USB 3.0 port and cable and get those speeds as well as charging rate. Or… Use a bog generic USB micro USB 2.0 cable and it would still fit on one side of the port and was still useable for USB 2.0 speeds and charging rates.
But I concede that it is one of the worst and most delicate ports ever stuck on something expected to have a plug jammed in it literally a thousand times.
