Micro USB is smaller, slimmer than Mini USB, which is older and larger.

Key Differences

Micro USB is a miniaturized version of the Universal Serial Bus (USB) interface developed for connecting compact and mobile devices. Mini USB, on the other hand, is an older standard of USB interfaces that preceded Micro USB. Both Micro USB and Mini USB were designed to standardize and streamline the process of connecting devices and transferring data.
The design of Micro USB is much smaller and thinner compared to Mini USB. While Micro USB was adopted widely due to its ability to accommodate smaller devices, Mini USB was the preferred choice for slightly larger portable devices before Micro USB became prevalent. Both Micro USB and Mini USB provide the convenience of universal connectivity, but their physical characteristics set them apart.
Durability is another factor where Micro USB and Mini USB differ. Micro USB was engineered to endure approximately 10,000 connect-disconnect cycles, significantly more than the Mini USB, which is rated for around 5,000 cycles. Both Micro USB and Mini USB were essential developments in their time, reflecting the technological advancements of the era.
The adoption and usage of Micro USB have been more extensive in comparison to Mini USB. Most modern smartphones, for instance, use Micro USB (or have transitioned to USB-C). Mini USB, conversely, is now less common and is typically found in older devices like digital cameras and MP3 players. Both Micro USB and Mini USB, however, helped pave the way for the standardized connectors we use today.
Micro USB, featuring a black receptacle and a 5-pin design, is distinguishable from the Mini USB, which has a white receptacle and a 5-pin design as well. Both Micro USB and Mini USB have contributed significantly to the world of technology, facilitating the universal compatibility and convenience that many have come to rely on in digital devices.
