Micro-USB vs. Mini-USB

Micro-USB (Micro-B) was the dominant charging and data connector on non-Apple smartphones and small electronics from the late 2000s through the mid-2010s. Its USB 3.0 variant added a second, wider tab beside the standard 5-pin plug for extra SuperSpeed pins -- a design most phone makers skipped, keeping plain USB 2.0 Micro-B nearly universal in practice.

Mini-USB (Mini-B) was a compact 5-pin connector common on digital cameras, MP3 players, and the original PlayStation Portable in the mid-2000s. USB-IF deprecated the Mini connector family in May 2007, and Micro-USB replaced it in nearly all subsequent compact-electronics designs.
