You probably noticed an extra-large USB port on the bottom the Galaxy Note 3 in both our initial hands-on and today’s unboxing. In case you were wondering, yes, that is a microUSB 3.0 port. The benefits are pretty simple – you can charge faster while being connected to a computer (900mA output), and also transfer data to and from your phone at faster speeds. That’s pretty much it.
Also, you can still charge and transfer data using a regular microUSB 2.0, you’ll just more than likely want to take advantage of the faster speeds when possible. But in case you are in a pinch and only have a regular microUSB cable, you’ll still be fine.
