Abstract: An electronic device includes at least a battery, a working circuit, and a boost circuit. When the battery supplies power to the working circuit, the boost circuit supplies power to the working circuit in response to that the electronic device meets a low-temperature or low-voltage condition. In a power supply path switching process, the boost circuit first supplies power to the working circuit through a diode, and then disconnects a path for supplying power to the working circuit by the battery. Before the path for supplying power to the working circuit by the battery is disconnected, a voltage for supplying power to the working circuit by the boost circuit through the diode is controlled not to be higher than a voltage for supplying power to the working circuit by the battery.
