The Oppo Ink screen mode refers to an energy-saving mode of Oppo mobile phones, which reduces screen power consumption by using a black and white display interface, thereby extending the battery life of the phone. In ink screen mode, the Oppo phone screen displays a black and white tone, only text and simple ICONS, and does not display high-power content such as color images and videos. The ink screen mode can be turned on or off in the phone's Settings.
