Why a black background enhances the autonomy of your smartphone? [Exclusive Guide]
The battery life of a smartphone does not only by the capacity of the battery. It also depends on the use made and personal optimizations that it brings. We will not return to the many tricks to save battery in this article but we will offer you a new, the use of a black background, and explain why it is so effective on some smartphones.
the background black, useful only on some smartphones
before anything else, it is important to clarify a detail, a black background is used effectively to reduce battery consumption and of improve the autonomy of your smartphone but only if the latter is equipped with an AMOLED screen. AMOLED and OLED screens, the LEDS remain off when they appear black, it is also for this reason than the famous mode Always we Display of S7 and S7 Edge Galaxy consume so little power since only a few whites (and color) pixels visible on the screen are lit.
If you have a smartphone with an IPS or LCD display, the black background you will not strictly help since all LEDS remain lit, even when the display shows black. It is also for this reason that blacks are much more intense and prettiest on the AMOLED panels. However, rest assured, with AMOLED screen smartphone are becoming increasingly common.
which smartphones offer AMOLED screens?
Most Samsung smartphones are equipping themselves to AMOLED screens. Only some entry-level models offer even LCD screens. It must be said that the cost of the AMOLED screens once higher than that of the competing plates to significantly down. In 2016, many manufacturers have proposed OLED or AMOLED screens. We include this technology over the Huawei P9, OnePlus 3, versions Pro and Porsche Design of Huawei Mate 9, Xiaomi Redmi Pro, Xiaomi Mi Note 2, the ZTE Axon 7 or even the Nexus 6 p and Google Pixel and Pixel XL.
A non-exhaustive list which shows that AMOLED screens are increasingly present on the market. Manufacturers seem to have finally become aware of the benefits they bring in terms of quality display than of autonomy.
Is the gain of independence really significant?
What autonomy gain hope in opting for a black background on a smartphone to AMOLED screen? A question the U.S. site Greenbot had tried to answer two years ago by testing the second generation of the Motorola Moto X which are fitted precisely this technology. A test that had allowed to estimate this gain up to 41%. This was already quite encouraging.
Of course, as you can imagine, this gain varies from one smartphone to another. Also other factors play also on the energy consumption of the screen, including its definition. However, the good news is that every year, the energy efficiency of the AMOLED slabs improves. Mean, they consume less in less than energy and impact less autonomously from your smartphone.
The screen of the Samsung Galaxy S7 / S7 Edge is more economical in energy than the Galaxy S6 which itself offered energy efficiency that the rating 4 or the S5 and like every year, it gets better, cuvee 2017 will be even better than the previous.
What black background use?
