How to Enable Grayscale Mode on Android

Android 10 recently launched an uber cool dark mode that immediately won the hearts of a lot of users. Apart from looking great, it also saves a lot of battery. The inverted colour theme has replaced the overbearing white space in the background of most apps with black. This consumes a lot less power by significantly reducing the chromatic and luminous intensity of the pixels that make up your screen. Due to this reason, everyone wants to switch to dark mode on their Android devices, especially when using the device indoors or at night. All the popular apps like Facebook and Instagram are creating a dark mode for the app interface.

However, this article is not about dark mode because you already know a lot about it if not everything. This article is about the Grayscale mode. If you haven’t heard about it then don’t worry you are not the only one. As the name suggests this mode turns your entire display into black and white. This allows you to save a lot of battery. This is a secret Android feature that very few people know about and after reading this article, you are going to be one of them.

What is Grayscale Mode?

The Grayscale mode is a new feature of Android that allows you to apply a black and white overlay on your display. In this mode, the GPU renders only two colours that are black and white. Usually, the Android display has 32-bit colour rendering and since in the Grayscale mode only 2 colours are being used, it reduces power consumption. The Grayscale mode is also known as Monochromacy as technically black is just the absence of any colour. Irrespective of the kind of display that your phone has (AMOLED or IPS LCD), this mode surely has an impact on battery life.

Other Benefits of Grayscale Mode

Apart from saving battery, Grayscale mode can also help you control the amount of time spent on your mobile phone. A black and white display is obviously less attractive than a full-colour display. In the present time, mobile phone addiction is a pretty serious issue. A lot of people spend over ten hours a day using their smartphones. People are trying various techniques to fight their urge to use smartphones all the time. Some of these measures include disabling notifications, deleting non-essential apps, usage tracking tools, or even downgrading to a simple phone. One of the most promising methods is switching to Grayscale mode. Now all the addictive apps like Instagram and Facebook would look plain and boring. For those who spend a lot of time gaming, switching to Grayscale mode would cause the game to lose its appeal.

Thus, we have clearly established the many benefits of this comparatively unknown feature hidden in your smartphone. However, unfortunately, this feature is not available on older Android versions like Ice Cream Sandwich or Marshmallow. In order to use this feature, you need to have Android Lollipop or higher. However, if you desperately want to enable Grayscale mode on old Android devices then you can use a third-party app. In the next section, we are going to show you how to enable Grayscale mode in the latest Android devices and also on old Android devices.

Switching to Grayscale mode will not affect your device’s performance in any way. On most devices, the GPU still renders in 32-bit colour mode and the black and white colour is just an overlay. However, it still saves a lot of power and prevents you from wasting a lot of time on your smartphone. You can switch back to normal mode at any time that you feel like. Simply select Off option under Stimulate colour space. For older Android devices, you can just tap the switch on the notification panel and you are good to go.
