Abstract:
1. A method for performing charging port detection control, the method being applied to an electronic device, a communication port of the electronic device having a functionality of obtaining power from an external power source for the electronic device, the method comprising the steps of: detecting whether an output voltage level of a battery of the electronic device reaches a first predetermined threshold value; and when it is detected that the output voltage level of the battery is less than the first predetermined threshold value, obtaining power from the external power source through a charger module of the electronic device to make the output voltage level of the battery reach the first predetermined threshold value or to make a system voltage of the electronic device be larger than a second predetermined threshold value, and then performing charging port detection on the communication port, wherein the system voltage corresponds to a system power terminal providing a system power to a system circuit of the electronic device.
