With the power standard increased to 20V / 5A and 100W power supply, USB Interface 3.1 can greatly improve the charging speed of the device, and at the same time can provide power for high-power devices such as notebook, projector and even TV. That's why Apple's new MacBook only needs a built-in USB Type C for power and transmission requirements.
Since USB 3.1 supports up to 10Gbps, it will greatly improve the transmission speed of the phone, which is a quantum leap over the previous USB3.0. This is very good for mobile phones. For example, more and more phones are beginning to support 4K video recording, and video files are getting larger and require faster data transfer speeds.
HDMI is a commonly used interface standard in TV and display products. Although miniature versions are available, few phones are specifically equipped with this port because of the increased cost and size. Since USB interface 3.1 supports display output, it is more suitable for use as an output interface for mobile devices, especially the reversible USB Type-C.
Obviously, small devices (such as phones and tablets) need universal interfaces and can greatly improve their connectivity. Type-C in USB 3.1 is the most likely connectivity standard of the future, providing integrated connectivity solutions such as data transfer, peripheral connectivity, and display output.
