Mobile phone USB is one of the most important access channels in mobile phones, and it is responsible for the two important functions of mobile phone power transmission and signal transmission. Mobile phone USB has the advantages of easy use, support for hot-plugging, flexible connection, independent power supply, etc., and is known for being "small, light, and thin". With the development of mobile phone wireless charging, wireless transmission and other fields. Some people think that mobile phone USB is facing a crisis of being eliminated by the market.

In fact, the main force of mobile phone data transmission is no longer USB. As long as there is a signal, data can be transmitted between mobile devices. Bluetooth, NFC, Wi-FiDirect, AirDrop... It has become less and less common that data needs to be transferred via USB. At the same time, wireless charging is developing rapidly, and magnetic charging has been officially applied. With the concept of non-porous mobile phones, mobile phone USB seems to have become a thing that has been left behind under the development of the times.

Perhaps this is inevitable, but not immediately. Just as the arrival of the WiFi era did not quickly eliminate Ethernet, wireless technology will not replace USB. When wireless transmission and wireless charging still have problems such as slow speed, low flow, insufficient stability, and insufficient compatibility. Mobile phone USB is still indispensable.

However, in the face of the crisis of being eliminated, USB manufacturers are also constantly promoting connector product updates. To meet the needs of a wider range of applications.
