How black wallpaper can save you battery power on Android

Hey guys, today is kind of a good day because today you will be learning something really different. Ok, the topic title already says it all but before we dive into the main details we have to understand the different kind of screen technologies we have. I would have loved to tell you guys what you need to know about touch screens and how they work but it will end up making this post very lengthy, so let's just cut to the chase. There are mostly 2 screen types used on devices, either AMOLED or LCD. These 2 screen technologies are also subdivided but we won't dive into that too, you can always google the rest up.

You see, the 2 screen types emit light using different methods, and they both have their pros and cons. AMOLED screens displays black as black and it also makes colors pop(Samsung's Secret), it also uses less power compared to LCD. That's because when AMOLED screens displays are suppose to show the black part of an image, then those pixels are off(are you getting my drift). Now, LCD on the other hand don't know how to display black clearly, they are always a little bit greyish(HTC why?), that's because LCD uses backlight for screen brightness and that backlight is always on thus the more power it needs. But one advantage the LCD has over the AMOLED is sharper display.

Now, after the whole explanation above, it will be okay to say, if your device is built with an AMOLED display, then you need a black wallpaper in order to conserve battery. Don't think this is some myth, the experiment has been carried out. What about LCD? well, the answer is really funny, to conserve more battery with a device built with LCD display, wait for it....... use a brighter wallpaper, guess you didn't see that coming. The whole explanation behind the LCD's display power conservation can be found here. So guys what are you waiting for start changing your wallpapers ASAP!!.
