Universal Serial Bus , commonly known as USB, connects peripherals to computers, creating a single common interface that modifies the port type of our computers . Although one end , the part that connects to the computer is of excellent quality , the connectors on the other end have multiple types. The most common nowadays are micro and mini connectors. The main difference between micro and mini USB connectors is their size. The two have the same width , though , the micro USB connector is about half the thickness of the mini USB connector. The key to the development of the micro USB connector is to create a thinner connector that will fit nicely into today's very thin mobile phones without taking up too much space. Although the Mini USB connector is already quite small , its thickness is one of the limited components to deal with phone designers. The introduction of micro USB has improved their design. Another area where the micro USB connector is better than the mini USB , durability. Since they are not meant to be in place all the time , it is important that the connectors , especially the gadget components, are able to handle some misuse. The micro USB connector is designed for cycles in 10,000 shifts , which is twice that of the Mini USB 5000 . Parts that can be expected to be abused in many ways, such as leaf spring connectors, have also been removed from the planet to the alley ; So that the circuit board of the cheap and easily replaceable wiring device is more likely to fail from inside the hard-wired. This simply reduces the chances of costly repairs to the device due to the connector. Because of these advantages , Mini USB is slowly moving step by step in favor of the new Micro USB. Phone makers have even used mini USB connectors before which are now moving towards micro USB. Some devices and manufacturers may still use the Mini USB connector for years to come. But it will gradually disappear as widespread use of the micro USB feature. Mini USB seems to have little chance of replacing the standard B plug used in printers and such devices.
