Abstract

Disclosed is a screen brightness adjustment method. The method includes that: a current battery power value and a current screen brightness value of a terminal are acquired; a target screen brightness range suitable for the acquired current battery power value is selected by taking the current screen brightness value as a baseline; a screen brightness value corresponding to the current battery power value is selected according to power consumption values corresponding to all selected brightness values in the target screen brightness range; and display is performed according to the selected screen brightness value. The disclosure also discloses a screen brightness adjustment apparatus.
