Hello readers ,|
Most people know the display is one of the most battery-hungry elements of any smartphone, but what they don't know is that the wallpaper they choose – yes, wallpaper – can make a significant difference to battery life. A pure black or generally dark-colored wallpaper or background can actually save power over a lighter one. It just depends on the type of screen you have.

Display tech explained: LCDLCD stands for Liquid Crystal Display and it's the same kind of technology you'll find in your televisions, monitors and so on. As the name suggests, Liquid Crystal Displays are actually crystals, and as such, they don't emit light of their own but rather transmit light from a light source behind them.This means that even if you're looking at black on your smartphone or tablet screen, it is actually black lit up from behind. Therefore, LCDs don't really display 'true' blackBattery life: AMOLED vs LCDAMOLEDYou can probably see where this is going: if you have an AMOLED display then you can save some battery life by using black wallpapers, or generally darker wallpapers and themes
LCDWhat about LCD battery saving wallpaper, I hear you ask? Sorry, LCDs rely on back-lighting, so there's nothing you can do to save battery there.The only thing you can do is set your device to Battery Saver mode and try not to turn your screen on all the time. Keep your display brightness as low as possible and your screen timeout nice and short.
AMOLED screensThere are other things AMOLED owners can do to maximize their battery life, such as setting as many app themes to be as dark as possible.If you can change the appearance of a bunch of apps you use frequently, you can save even more battery life. After all, we spend more time in apps than on our home screens. You can also set your text and email preferences to have a black background and use white text, depending on your device and chosen apps.The easiest way to figure it out for yourself is to fully charge your device as is and wait until it's almost totally dead and look at how much of your battery was used by the display. Just go into Settings and look for Battery, usually in theDevice Settings/Device Maintenance section..Give me black wallpaper nowTo download a straight black wallpaper for your smartphone background, hit the link here, and don't forget to change your app themes to be as dark as possible to enhance the battery-saving effects.You can also set a darker system-wide theme for your device, change your screen timeout setting to be as short as possible, enable power saving mode, turn off auto-brightness and see how great the battery savings are.Of course, your battery is used by more than just display, so results will be dependent on your phone usage habits, processor and other variables, but the savings will still be worthwhile.
