Store description excerpt
Black 4 Battery is a minimalist tool designed for power users who love multitasking. Do you use apps in pop-up or floating windows? Black 4 Battery provides a pure black, system-level backdrop that covers the rest of your screen. Key Features: OLED/AMOLED Friendly: Since true black pixels turn off on OLED screens, this app helps reduce battery drain while you work in other windows. Distraction-Free: Hide messy wallpapers or background apps to focus entirely on your active floating window. Instant Brightness Control: Quick-toggle between dim and normal modes, or use the slider for precision control. True Fullscreen: Hide system bars for a completely immersive black canvas. Simple, lightweight, and battery-efficient. Perfect for watching videos or reading in pop-up mode.
