Why Use AMOLED and 4K Wallpapers on Modern Smartphones?
Modern smartphones from Samsung, Apple, Xiaomi, and Google feature OLED and AMOLED displays capable of individually switching off pixels to achieve true infinite contrast. When you use a dark or AMOLED-themed wallpaper on your smartphone, your screen draws significantly less battery power because black pixels consume virtually zero milliwatts.
Optimized for Retina & Quad-HD+ Displays
