Almost all latest devices now support USB 3.0 architecture. If you don’t know what that is, in simple words, USB 3.0 is the updated “version” of USB that makes data transfers faster, and passes more current between devices.
Redditor Company_Rep recommends that if you charge your phone through a USB cable and you have a USB 3.0 port, you can use that. It will charge faster as it is can draw more current than USB 2.0 ports.
Another redditor further adds:
For reference, many laptops now have a Yellow USB port. This is designed for charging devices and can be set to still charge even when the computer is inactive/powered off.
This is a great tip for school students and travelers who are mostly on the go, and need their phones to be charged.
