METHOD AND TERMINAL FOR DETERMINING TERMINAL PROCESSOR VOLTAGE

Embodiments of this application relate to a method for determining a voltage of a processor of a terminal, and a terminal. The terminal includes a CPU and an auxiliary processor. The method includes: in a switch-on process of the terminal, after completing system initialization, determining, by the auxiliary processor, a minimum working voltage of the CPU; setting, by the auxiliary processor, a current voltage of the CPU to the minimum working voltage; and completing, by the CPU at the minimum working voltage, the switch-on process of the terminal, and controlling the terminal to work. In the method for determining a voltage of a processor of a terminal, and the terminal in the embodiments of this application, a minimum working voltage of a CPU is determined in a switch-on process of the terminal. Compared with that a minimum working voltage of a processor is measured by using a test machine during production of the processor, in the present invention, a testing time and testing costs can be reduced, testing precision can be improved, and a minimum working voltage of a processor can be more accurately tested.
