Do you ever wander how much power your background cute wallpaper uses on your phone, tablet or wallpaper live? Do you ever think about your wallpaper when your battery is dead? If you want to save power you should find yourself a as dark as possibly wallpaper (planwallpaper.com). You may think why, and that is a good question. Dark pixels need less power, because when they are off they are also dark. So if you remove your wallpaper in total, and use a black background it add much battery time.
