As we all know, Apple has always used the lightning interface, but with the development of charging technology, apple is also slowly replacing this technology. At present, many devices have transitioned to the type-C interface, such as MacBook series, iPad series and studio display currently on sale.

  according to a previous report by the central media, it is expected that by 2024, all portable electronic device charging ports in the European Union will be unified with type-C interface, while the mainstream models of domestic mobile phone manufacturers have been switched to type-C interface, and the domestic fast charging standard will be unified later.

   why didn't Apple give up this interface and adopt the type-C interface instead? First of all, we should know that the absolute advantages of type-C are obvious. For example, it supports fast charging power of up to 100W, and there are many compatible protocols. The transmission rate can reach up to 40Gb / s. However, Apple's lightning technology is old, with high delay, low charging speed and poor compatibility. Because only Apple's devices have this interface, it needs to buy an docking station to realize more functions.

    apple is also a chicken thief, so it adds lightning interface compatible type-C to all productivity oriented devices, such as MacBook and iPad pro, but entertainment oriented devices such as iPhone still use lightning interface. From the perspective of cost, the production cost of lightning may be higher than that of type-C, but Apple still chooses to use it. Why is apple, which has always advocated environmental protection, unwilling to compromise on the issue of interface and realize the unified interface using type-C.
