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

• Wallpaper impact on battery life depends on wallpaper type and screen technology.
• Static wallpapers have minimal battery impact, while live or animated wallpapers can increase consumption by 10-25% due to continuous GPU/CPU activity.
• On OLED/AMOLED screens, dark or black wallpapers save battery as pixels turn off; bright wallpapers consume more.
• LCD screens are minimally affected by wallpaper color because their backlight is always on.

Why It Matters: Optimize battery life by understanding wallpaper and screen tech impact.
