Claim 12:
13. A power supply method for a terminal device, wherein the power supply method comprises:
controlling, by a controller of the terminal device, a voltage boost circuit having an input end coupled to a positive electrode of a battery and an output end coupled to a load of the terminal device to work and a battery chip having a first end coupled to the positive electrode and second end coupled to the load to stop supplying power to the load when a sampling temperature is less than a preset temperature value or a first output voltage of the battery is less than a first preset voltage value, wherein the sampling temperature is a first temperature of the terminal device or a second temperature of the battery; and
controlling, in a working process of the voltage boost circuit, the battery chip and the voltage boost circuit to simultaneously supply the power to the load when a second output voltage of the voltage boost circuit is less than an input voltage of the voltage boost circuit.
