Wallpaper & Battery: Live Wallpapers Drain Most, Dark Saves OLED

• Static wallpapers have a negligible effect on smartphone battery life.
• Live or animated wallpapers significantly drain battery due to constant rendering and CPU/GPU activity.
• On OLED/AMOLED screens, dark or black wallpapers conserve battery by turning off pixels.
• On OLED/AMOLED screens, bright or white wallpapers consume more power as all pixels work at full intensity.
• Wallpaper color has a negligible impact on battery life for LCD screens, as the backlight remains constantly on.

Why It Matters: Your wallpaper choice can significantly impact your phone's battery life.
