Abstract
A method and an apparatus for performing charging port detection control are provided, where the method is applied to an electronic device, a communication port of the electronic device has a functionality of obtaining power from an external power source for the electronic device, and a power path switching unit of the electronic device is arranged to control electrical connection between a system within the electronic device and a battery of the electronic device. The method may include the steps of: performing charging port detection; and control operation(s) according to the charging port detection. For example, the method may include: controlling the power path switching unit to have different configuration according to the charging port detection in order to charge the battery with different charging profiles; and detecting the system voltage level during charging for switching from the constant current mode to the constant voltage mode.
