Dark mode is a feature in many apps and operating systems that changes the colour scheme from the traditional light colours to a darker colour palate. The main benefit of this change is the reduction in glare from the screen when using a dark mode app in a dark environment. Dark mode can make the screen appear a lot less bright than it would be with a traditional colour scheme. This significantly reduces the impact on your dark vision and the strain it can put on your eyes.
Dark mode can also help to reduce the power usage of some devices. OLED and AMOLED screens produce light directly from their pixels rather than using a backlight like traditional LCD screens. In this case, pixels displaying darker colours use less power, while a black pixel can be turned off entirely and uses almost no power.
The YouTube app on Android is one of many apps that support dark mode. To enable it you need to configure YouTube’s in-app settings.
The first step to enable dark mode in the Android YouTube app is to tap on your profile picture icon in the top-right corner of the app.
On the account configuration page, tap “Settings”, which should be the second to last option in the list.
Next, you need to tap the topmost setting, labelled “General”.
To enable dark mode tap “Appearance”, the third from the top option in the general settings. A popup box will appear with three options: “Use device theme”, “Light theme”, and “Dark theme”.
By default, like many other apps, YouTube will match the system theme of your phone by using the “Use device theme” setting. You can manually override this setting to enable dark mode by tapping “Dark theme”. The theme change will instantly apply.
