In June 2004, major global mobile network operators such as Orange, T-Mobile, O2, Spain, Telecom Italia and Japan's NOIN, as well as major mobile phone manufacturers such as Nokia, Samsung, Motorola, Sony Ericsson and LG, established an open mobile terminal platform organize. In September 2007, OMTP announced the global unified mobile phone charger interface standard as Micro USB. The new Micro USB specification supports USB technology on mobile devices such as mobile phones, and prepares for smaller and more compact portable devices in the future. . Mobile phones, MP4, digital cameras and other portable devices can be interconnected and communicated without a PC. In the future, the mobile phones produced by these several manufacturers will be committed to adopting the Micro USB standard, and strive to make it a unified charging interface for future mobile phones. The use of the Micro USB interface enables one interface for charging, audio and data connection.
On the other hand, in fact, the conclusion of this agreement is also the result of the active promotion of the EU. Xiwang WEEE department requires handheld device manufacturers to be responsible for the waste and pollution caused by interface differences, and hopes that the unified interface protocol can reduce this waste. Xiwang Geng suggested that the new phone can be packaged without the charger because people already have a Micro USB charger. This not only reduces waste, but also reduces packaging and shipping costs. In addition, an interface can be used for charging and data transmission, which can simplify various operations, which is also a good thing for users.
