Abstract: This application relates to terminal devices, specifically to a method for reducing device power consumption, an electronic device, and a medium thereof. The method identifies different video playback scenarios and determines if a user is still watching a video based on user inactivity in these scenarios. When it is determined that the user is not watching the video, the power consumption of the terminal device is reduced.

Abstract: This application provides a refresh rate adjustment method and an electronic device. The method includes: After playing at least one video source file in response to a first operation of a user, the electronic device adjusts a refresh rate of a display of the electronic device based on three factors, that is, a first frame rate of the at least one video source file currently played, a play status of each video source file, and whether an interaction operation is received.
