The background of our smartphone is constantly changing according to personal tastes: there can be wallpapers inspired by movies, cartoons, VIPs, works of art, landscapes and many others. All these wallpapers allow you to customize our smartphone in a simple and fast, but without knowing they make us consume a lot of battery; the ideal solution to this problem is the use of a black background or nero background.
The black background is, in fact, the ideal compromise to save the battery of our mobile phone, because focusing on the rendering of a single color, among other very dark, the processes to process the image are very reduced and thus significantly lengthen the life of the phone.
The black background also allows you to better enjoy the graphics of the installed applications, as they stand out against the neutral background selected for our device.
The issue of black wallpaper is very interesting, as its effectiveness may vary depending on the display of our smartphone, which can be both LCD and AMOLED.
Both react differently and have different consequences for using the black background for our screen; let’s see what are the main reasons for this difference in the black background.
Black background for smartphone: differences between LCD and AMOLED
Smartphones that have an LCD display are the most common on the market, and when an image is shown on this screen, it does not reflect its own light but uses the panels placed under these; this means that any image, even the black ones, on these displays will never be dark, because the panel located at the bottom of the display will give in every situation an impulse of light that will give brightness in any situation.
The other type of AMOLED displays mounted on as many smartphones are slightly different than the previously mentioned displays and behave differently in the question of the black background for mobile phones.
AMOLED phones displays may be considered “better” than LCDs because they use their own current to show the image on the screen that we will use, or that of the mobile phone in this case.
In AMOLED displays, there will be better battery savings than other displays, because with the use of a black background there will be less energy production because every pixel inside the image will be powered individually and not in an overall way as in the LCD display.
Black background on IPS display
Particular mention should be made of the IPS displays, which appeared recently on high-end devices (such as on the LG G3) and in the black background, they behave more or less like LCD displays, while ensuring a better viewing angle than the other type of display.
Summing up, the use of a black wallpaper and therefore the use of black backgrounds save a small percentage of battery per hour and therefore could be very useful for those who want to prolong the longevity of their smartphone.
Using a black background consumes less, but works only for the AMOLED display for the issues explained above.
We leave a gallery for anyone who wants to download the black background for their device and why not? Use it as a smartphone background, but above all we have also included the FullHD resolution, but also a black HD background that is good for both smartphones and tablets, but also for PC, here are the best black backgrounds:
In case you are interested in having a black background on Android or a black background on Iphone just download the files that we have posted previously and select them as the main wallpaper of the device.
Obviously, even if the black background consumes less it is mandatory to reconfirm the fact that this improvement will be much more noticeable on AMOLED and super AMOLED displays thanks to their ability to turn off pixels.
Make your choice.
