Abstract
In a method for controlling a screen protection function of a portable electronic device, the portable electronic device includes a gravity sensor, a display screen, and a storage system. The gravity sensor detects a horizontal vector and a vertical vector of a gravitational acceleration of the portable electronic device, and a tilt angle of the portable electronic device is calculated according to the horizontal vector and the vertical vector. The method activates a screen protection program of the portable electronic device to control the display screen to enter into a power saving mode if the tilt angle exceeds a preset tilt angle range stored in the storage system, and terminates the screen protection program to control the display screen to enter into a normal display mode if the tilt angle does not exceed the preset tilt angle range.
