Wallpaper Battery Drain: Static vs. Live, OLED vs. LCD Explained

• Static wallpapers have a negligible impact on battery life as they do not require constant GPU re-rendering.
• Live wallpapers consume more battery due to continuous animation and GPU usage.
• On OLED/AMOLED screens, dark wallpapers save battery by turning off pixels, while bright wallpapers use more power.
• On LCD screens, wallpaper color has little effect on battery life as the backlight is always on.
• HDR images or heavy gradients can slightly increase GPU load, potentially affecting older or budget devices.

Why It Matters: Wallpaper type and screen tech affect phone battery drain.
