It starts with the round socket of Nokia, Samsung, Motorola, and after the round socket comes the mini USB interface, which is more portable and compact. But due to performance not keeping up with gradual obsolescence. Subsequently, the micro USB interface emerged, which was also the one commonly used in the past. It has a smaller size, higher USB data transmission efficiency, and supports different charging protocols.

But why is it still difficult to eliminate micro USB with so many advantages? There are three reasons.

Firstly, the interface of the micro USB does not support forward and reverse port insertion. In case of urgency, it often inserts in the wrong direction. If the force is too strong, it will not only damage the cable. Secondly, currently type-c supports better power, up to 100W. And it supports forward and reverse charging and bidirectional charging. Finally, the type-c interface supports the USB 3.1 standard, with a transmission rate of up to 10Gbps. Greatly increased data transmission efficiency and reduced waiting time.

It is precisely because of the above points that type-C is widely used, not only on mobile phones, but also on devices such as computers and Bluetooth headphones. But even so, we still need to note that not all type-C ports are full of blood, and many on the market are residual versions.

Are you familiar with the common development? Quick reference, although the mini USB interface (old-fashioned interface) is a type of mobile phone charging interface, it is not a dedicated interface for mobile phones, it is only a standard for mobile phone USB interface. In the early days, it was mainly used for transferring data between small devices and computers, and can also be used to charge some devices that support this interface.

However, with the emergence of other standard interface technologies, the mini USB interface has gradually been phased out. Except for some old-fashioned phones, few phones use its most mobile interface.

The advent of the era of Android smartphones with micro USB interfaces has made the micro USB interface shine brightly. Early Android system phones used the micro USB interface. If the mini USB interface is from the 1.0 era of small device interfaces, then the micro USB interface is from the 2.0 era. Compared to the mini USB interface, in addition to improving transmission speed and efficiency, it also supports OTG functions and has a longer service life.

The type-c interface fast charging is completely different from the 1.0 and 2.0 era, and its shape has changed greatly. The mini usb interface and micro usb interface are shaped like a T-shape, while the type-c interface is elliptical, regardless of the reason. Different from the first two interface lines, type-c has more lines, more refined functions, higher transmission speed and charging efficiency. Most mobile phones in the market that support fast charging use the data lines and interfaces of the type-c interface.

There is nothing to say about the Lightning interface dedicated to Apple devices. In order to be compatible and support various devices, some organizations have developed device interface types and specifications, such as mini USB interface, micro USB interface, type-c interface, etc., which are international standards. However, the Lightning interface is an interface announced by Apple itself and is not compatible with other devices.

We all know that type-C ports will be more widely used in the future, especially with the emergence of higher transmission efficiency in USB4 and Thunderbolt 3, and the scope of popularization will also be further expanded.

But the better the type-C port, the higher its cost, which is also one of the reasons why there are residual blood versions of the C port on the market. Therefore, it will take some time for the type-C port to truly become fully popular.
