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.
