As a general rule, connecting a smartphone to a USB 3.0 instead of 2.0 port, will not make it charge faster. TheUSB 2.0, or “Hi-Speed USB,” specification significantly improved USB 1.1. The main improvement was an increase in bandwidth to a peak of 480Mbps. It has been superseded by its successor, the USB 3.1 standard, which delivers even higher speeds and power delivery capabilities than before while remaining fully backward compatible with Forexample, blue USB ports are typically associated with USB 3.0 technology, which offers faster data transfer speeds and more power delivery compared to older versions. Black USB ports, on the other hand, are typically associated with USB 2.0 technology, which is an older technology.

MartinArgerami The usually blue applies to the plug (not the cable) - "Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, USB 3.0 specification mandates appropriate color-coding and recommends that the Standard-A USB 3.0 connector has a blue insert (Pantone 300C color). xur8.
