Smart Invert as "night mode"

If you use the iPhone X with iOS 11, then you can do the so-called in the display adjustment Smart Invert, so activate the clever color inversion. Some sources also speak of an alternative "night mode" or a "dark mode". The setting ensures that the display is turned negative, which is particularly helpful when surfing the Internet, where a much lighter background with little black can be seen as writing. Except in third-party apps, the “smart” color inversion ensures that images and videos are displayed in the correct colors. And so you can activate the setting:

Settings -> General -> Accessibility -> Display adjustments -> Reverse colors -> Smart Invert

By the way, you can set up this setting as a shortcut as a convenience. Have you done this, you can go through pressing the side button three times quickly activate or deactivate the Smart Invert.

grayscale

If you activate the grayscale on the iPhone X, you will save even more battery power. Since no colors have to be displayed, not only are there no activities on the display - the CPU and graphics processor are also relieved somewhat. You can activate grayscale under iOS 11 on the iPhone X, just as it is possible with other iPhone models with an LCD instead of an OLED display:

Settings -> General -> Accessibility -> Display adjustments -> Color filter -> grayscale

Black background

Whether on the lock screen, the home screen, as a background on WhatsApp or elsewhere in the system - a completely black background ensures that the OLEDs remain off in the appropriate place. Unlike the display of colors or white (consumes the most electricity), a black background, just like the Smart Invert mode when surfing, can also be useful for checking time, searching for apps and other activities for saving the iPhone X battery. Apple even provides a completely black background in iOS 11 in the standard wallpapers.
