Abstract

A method and an electronic device for controlling display refresh rate of an electronic device include operations as follows. When there is at least one foreground application currently running is a predefined application of a white list, a predefined refresh rate of the at least one foreground application is obtained and a target refresh rate of a display screen of the electronic device is determined according to the predefined refresh rate of the at least one foreground application. A frame buffer of the electronic device is controlled to send frame data to be displayed to the display screen at the same frequency as the target refresh rate.
