How Black Wallpaper Can Save You 8% Of Battery Every Hour On Your Smartphone

Everyone needs smartphones that can last long with heavy usage but most of the time we make wrong choices when purchasing a phone that’s intended to suit our needs.

Nowadays, smartphones have been designed with some crazy pixel densities that consume power. Displays usually take the largest percentage of battery power when you check the log in your battery monitor app, thus hogging your battery life. So when you want that 4K smartphone and dream about an 8k phone, don’t forget the nightmare from the battery. Haha!

Most people don’t know that pure black wallpapers can decide your battery life. But there is more, this will only work on certain types of display.

So here’s what we propose.

Each time you want to purchase that phone, instead of focusing on the battery capacity which of course is the latest trend. Determine the display panel of the device.

15 Ways To Improve Your Android Battery Life

Most people don’t know that pure black wallpapers can decide your battery life. But there is more, this will only work on certain types of display.

If your smartphone comes with a LCD display like most of the smartphones you love, this technique will not work for you. The reason of this is because these type of display needs a light source that’s normally placed behind them, which lit up the crystals; they require light even for black colours.

On the bright side, OLED and AMOLED displays do not work like the so-called LCD screens. The diodes in them require current to produce colours, but black colours do not need light. It therefore means that you get true black colours on LED and AMOLED screens, unlike the LCD where the black colour is forced from a light source.

So the next time you want to buy a phone, the battery capacity shouldn’t be your only priority, but the display panel that’s equipped on it. Samsung and LG smartphones usually come with AMOLED display, just in-case.

If you use an LCD screen, there is no point using a black wallpaper, it won’t have any effect. But if your phone packs an AMOLED, LED or OLED display, then dark wallpapers should work like a charm for you.
