One of the best features of Android 10 is the Dark Theme option (commonly known as dark mode for some reason). The Dark Theme option modifies the color palette of all menus and most Google apps, including Chrome and YouTube, making them better for usage at night. More and more app developers are working on introducing Dark Theme support.
Why is this important?
Dark Theme is extremely useful when you analyze it on a more technical level: The display is the biggest power drain of a phone, so it makes sense that glowing less translates to a lower power usage by a significant amount.
The option works most efficiently on OLED displays.
Dark theme is also easier on the eyes because users are exposed to less light.
Activating Dark theme: method 1
The simplest way to activate Dark Theme is through the settings of the device: Go to settings>display and then tap the toggle for Dark theme, and it should activate right away.
Activating Dark theme: method 2
This method involves adding the Dark Theme option to the phone’s quick settings (the big toggles which appear on the notification bar when you pull it down).
Pull the notification bar down and then tap the pen icon located at the bottom part of the tile drawer. This will display a separate set of icons which can be added to tiles. Tap and drag the Dark Theme tile into the main folder and place it where you desire to (maybe next to the wi-fi toggle as you’re most likely going to use this one a lot, too).
Users of Pixel phones that run up to date Android can turn on Dark Theme in a different way: Entering the Battery Saver mode will automatically turn on the Dark Theme mode.
