AMOLED Wallpaper
AMOLED wallpapers are designed with true black (#000000) areas that save battery on OLED screens, since black pixels are physically turned off and consume zero power.
AMOLED (Active-Matrix Organic Light-Emitting Diode) displays work differently from traditional LCD screens. Each pixel produces its own light, and when a pixel needs to display pure black, it simply turns off. This means wallpapers with large black areas reduce the number of active pixels, directly lowering battery consumption.
AMOLED wallpapers are designed to maximize these black areas. Common styles include true black backgrounds with subtle accents, dark geometric patterns, space imagery with black voids, and minimal designs on black canvases. The key is using pure black (#000000) rather than dark gray — only pure black fully turns off the pixel.
One4Wall and Thematica both offer curated AMOLED wallpaper collections. Pair them with dark icon pack variants (Ares Black, Ares Dark, Lena Dark, Lena Black, or Caelus's default dark theme) for a cohesive dark setup that looks great and saves battery.
Tip: Most flagship phones from Samsung, Google, OnePlus, and Apple (iPhone X and later) use OLED or AMOLED screens. If your phone has an LCD screen, dark wallpapers won't save battery — but they still look great.
