In Handy Tips, we find ways to improve your life and make it easier and explain why these tips work. Today, we will tell you how the dark mode saves battery life and also helps reduce eyestrain.

The dark mode can save battery life quite a lot

Many users prefer the dark mode not only because it allows their eyes to rest in a lack of ambient light, but also because the dark mode saves battery life. While it's hard to believe, using the dark mode does minimize the battery drain on devices with AMOLED displays. Therefore, the default design of the WhatsApp interface did not suit a certain audience of users, and they asked the developers to make it pure black.

How to customize WhatsApp

The developers of the messenger made concessions to users and added a dark mode and several options for monochromatic wallpapers. Now users can choose the shade they like and not only save battery life by making the smartphone screen consume less power, but also reduce eyestrain.

For example, if your eyes are watery from a pure black background, you can choose a dark burgundy, so the situation will significantly improve, and you can, though without much comfort, but no longer in tears, perceive the content on the screen. Therefore, experiment to find out what is right for you.

How to change the background in WhatsApp

To make the background in WhatsApp chats pure black:

  1. Open the messenger’s app and go to the context menu.
  2. Open "Settings" and find the "Chats" section.
  3. Open the "Chat Wallpaper" tab and go to "Solid Colors."
  4. Pick a solid black color, apply it, and save your changes.

How the dark mode saves battery life

Research has shown that the dark mode (pure black) can extend battery life by up to 40% of baseline. For this, a smartphone must have an AMOLED display, because it consists of many LEDs, which, unlike IPS panels, do not have a single backlight, but are turned on and off independently of each other. Therefore, where it is necessary to display a black color, the LEDs go out and do not use the battery at all.
