Battery saving, visual comfort… All about the dark mode of your devices


You’ve heard of “dark mode”, but you don’t know what it is. Or maybe you don’t know how to do it on your device? Don’t panic, here’s everything you need to know about dark mode.

Surely you have seen it appear on websites, in the menus of your phone or even in some applications that you use every day… Dark mode is now an important part of our digital life. But concretely, what is this new option that many on the Web for? Why are all the sites suddenly starting to offer this? And how is it possible to take advantage of it?

Today, we tell you all about this discreet feature, which can improve your browsing experience on smartphones, tablets or computers.

What is dark mode?

Not surprisingly, dark mode (or “dark mode”, as it is called in Anglo-Saxon) has its Wikipedia page describing the phenomenon. “dark mode […] a color selection (or theme) applied to icons, texts and human-machine interfaces displayed on a dark background on a website or an operating system.“To put it more simply, it is the act of moving the user interfaces (usually designed on a white background) of a website or an application to a darker color palette, or completely black.

Be careful not to confuse this with the “night mode” that some PCs and some phones offer. This option has the effect of yellowing the screen to reduce the user’s exposure to blue lights. The dark mode is also not a simple transition to the “negative” of a website in light mode, because it often requires redesigning logos, buttons and menus to provide the most comfortable and ergonomic experience. navigate as possible. . A successful dark mode requires that each development team behind each website or application rethink, to a greater or lesser degree, its service interface. So you shouldn’t see the option anywhere on the web. Behind this small aesthetic change are the problems of ergonomics and legibility.

What is dark mode for?

The easy​​​​​​ answer to this question is “offer more choice”. It turns out that Internet users prefer darker interfaces for reasons of reading comfort. The dazzling white of Google’s homepage, for example, is not necessarily suitable for surfing sessions on a smartphone from under your bed in the dark. But dark mode also has more technical advantages: it allows, in some cases, to save energy and therefore the battery of his phone or tablet.

Oled screens, which are now widely available in our phones, TVs and game consoles, have the advantage of not eating anything when the screen is black. Unlike IPS screens that require a constant backlight from the panel, OLED can turn off some of its pixels individually. As a result, the display of a black screen is not used, because there is no need for a backlight mechanism.

If your smartphone (or your tablet, or your PC) has an OLED screen, activating dark mode turns off some parts of the screen and therefore saves battery power. However, this only works in “true” dark modes with a black background. Many applications or websites opt for a blue gradient as a dark mode. So the latter does not offer an advantage in terms of energy consumption (because each pixel is present), but offers those who want it better reading comfort.

True Dark Mode may also be suitable for some accessibility issues thanks to clearer contrast. Less white background, there is also little blue light.
