Energy Saving in Smartphones by Using Dark Wallpaper on OLED
One way to save battery life on your smartphone is to use a dark wallpaper. OLED displays, which are used in many smartphones, work by turning on individual pixels to create images. When a pixel is turned off, it doesn’t use any power. This means that dark mode on an OLED display can save a significant amount of power, because most of the pixels on the screen are turned off.
