Abstract

The invention provides a method and device for saving electric energy as well as a mobile terminal, and the method, device and mobile terminal provided by the invention are suitable for the field of mobile communication; and the method comprises the following steps: obtaining the current running task of the mobile terminal; according to the current running task, adjusting the CPU (central processing unit) frequency on the basis of the corresponding relation between the predetermined setting task and the CPU frequency. In the invention, the current running task of the mobile terminal is obtained firstly, and then the CPU frequency is adjusted without increasing the hardware cost on the basis of the corresponding relation between the predetermined setting task and the CPU frequency according to the current running task; and different CPU frequencies are required to be used for different tasks so that the purpose of saving electric energy is achieved.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method, a device and a mobile terminal for saving electric energy. Background technique [0002] Currently, energy saving has become an important design index in the design of mobile terminals. In the field of Smart phones, some mobile terminals have achieved energy saving and consumption reduction through multi-CPU systems. Using multiple CPUs will undoubtedly increase the cost of hardware; in the field of Feature phones, most mobile terminals still run on a single CPU, and all tasks The CPU is completed, and if the CPU cannot be run reasonably, it will cause a waste of electric energy. Contents of the invention [0003] The purpose of the present invention is to provide a method for saving electric energy, aiming at solving the problems of wasting electric energy or high production cost during the operation of the existing mobile terminal. [0004] The pres...
