Dark Mode on Android smartphone helps save battery life, admits Google

Google finally confirmed that the Dark Mode uses less power and helps increase battery life on Android smartphones, SlashGear reported. During a presentation at the 2018 Android Dev Summit, Google urged its developers to use darker colors in their apps to get the best battery life on the end user’s phone.
Generally, when you increase the screen’s brightness, it affects the battery life of the device. Also, the color displayed affects the power consumption of the display.
The Dark Mode basically reverses the color theme of an operating system (OS) or applications by replacing the white background with black. The Dark Mode for long has been associated with better battery life on devices, especially mobile devices.
According to Business Insider, Dark Mode draws 43% lesser power at full brightness compared to “normal mode” in the YouTube app, which normally uses a lot of white. The white color indirectly utilizes more power than darker colors.
Google also admitted their past mistake of encouraging app developers to use the color white for their applications and interfaces, including its own apps with their official Material Design specification for the last few years. The search giant said that they have plans to roll out a Dark Mode for all the Google apps in the future.
Please note that changing to Dark Mode only changes the user interface (UI) color to black background. You may have to manually enable Dark Mode on different applications.
For instance, to enable Dark Mode on your Android smartphone, you need to follow the below steps:
  1. Go to Settings on your phone.
  2. Tap on Display > Advanced > Device Theme.
  3. Tap on Dark.
Similarly, you can enable Dark Mode for YouTube application as given below:

  2. Then, tap on your profile icon that appears on the right top corner.
  3. Go to Settings > General.
