1. A terminal, comprising a processor coupled to a memory, wherein the processor is programmed to:
- obtain a usage and a working frequency of a working CPU;
when the usage is greater than a usage threshold, determine whether the working frequency is smaller than a first frequency;
determine the working frequency as the first frequency when the working frequency is smaller than the first frequency, wherein the first frequency is smaller than a maximum frequency of the CPU;
when the working frequency is greater than or equal to the first frequency, determine whether the working frequency is smaller than or equal to a second frequency, wherein the second frequency is greater than the first frequency and smaller than the maximum frequency; and
determine the working frequency as the second frequency when the working frequency is smaller than or equal to the second frequency.

Abstract
The present invention discloses a method for controlling a central processing unit CPU. A usage and a working frequency of a working CPU is obtained. When the usage is greater than a usage threshold, it is determined whether the working frequency is smaller than a first frequency. The working frequency as the first frequency is determined when the working frequency is smaller than the first frequency. The first frequency is smaller than a maximum frequency of the CPU.
