Abstract: An electronic device with hybrid power source includes a system circuit, a charging and discharging circuit, a power connector, two batteries, and a controller. The charging and discharging circuit is connected to the system circuit, the power connector, and the two batteries. The controller is connected to the processor and the charging and discharging circuit, and the controller has a hybrid power supply mode. The controller detects the operating power of the processor in the system circuit, and controls the power mode from a single power mode to a hybrid power supply mode in response to that the operating power reaches or exceeds the power threshold. In the hybrid power supply mode, under control of the controller, the processor releases a power limit, and the charging and discharging circuit powers the system circuit by using both the battery with greater energy level and an external power.
