With the increasing popularity of OLED displays, companies like Apple, Google and Samsung have all shifted away from traditional LCD screens for their flagship units. An OLED screen provides deeper blacks and is better for battery life, as each pixel can be individually controlled while emitting its own light. This, in turn, has made dark themes an important software feature.
Recently, Google investigated battery-saving effects of dark mode and the results were surprising. With the YouTube app in particular, dark mode can reduce battery consumption by up to 60% – no wonder they recently added the feature to the app for both Android and iOS. Side-by-side battery saving, dark mode helps lighten your eyes at night and provides a more immersive experience while watching videos, so there's virtually no reason not to get this setting enabled.
Step 1: Update or Install the YouTube App
YouTube is pre-installed on almost all Android phones, but you can install it from the Play Store if it is not. I'm also sure many of you already have the YouTube app on your iPhone, but only if you don't do so can you go and download it from the App Store. You should also make sure that the app is updated to the latest version to access the dark mode feature.
Now open the YouTube app and tap your profile icon in the upper right corner and then select "Settings."
From here, if you are using an iPhone, just enable the switch next to "Dark Theme". If you are on Android, select "General" first, and then enable the "Dark theme" button.
Now you can enjoy the new dark theme of the YouTube app on Android! What can you expect from activating dark mode? The background color of all menus will now become dark with the text white, making it more ideal for battery life. Not to mention, it is also easier on the eyes at night. It's a win-win all for all current and future screens, not just OLED.
If you ever want to disable dark mode in YouTube, just repeat the above steps, but this time, switch the switch next to "Dark theme" to shutdown instead.
