Abstract: A rapid charging method and a system for a mobile terminal are provided, which are capable of increasing charging current and dissipating heat. The method includes communicating a controller of the mobile terminal with the charging accessory through a Type-C interface after the mobile terminal detects that the charger is connected to an electric power supply; turning on a load switch by the controller, so that the microcontroller controls a first charging integrated circuit (IC) to start charging, and the controller controls a second charging IC of the mobile terminal to start charging; and stopping charging of the second charging IC of the mobile terminal, and charging the first charging IC of the charging accessory until power of the battery is full when a charging current gradually decreases to a threshold.

Abstract: The present disclosure generally relates to the technical field of mobile apparatuses, and discloses a method and a device for an earphone and a USB to share a Micro-USB interface. The method comprises the following steps of: A. detecting whether USB lines or earphone lines are plugged into the Micro-USB interface and generating a corresponding control signal to a control module by an interface detecting module; and B. selecting to activate a USB task or turn on an audio path according to the control signal by the control module. The present disclosure allows the earphone function and the USB function to be achieved through a single Micro-USB interface (i.e., the battery charger, the data lines and the earphone function are integrated together), and can be implemented in a simple structure and at a low cost.

Abstract: The present disclosure provides a mobile terminal, which comprises a charging port, a power management unit (PMU), a battery, and a charging surge protection circuit disposed between the charging port and the PMU.
