Are you looking for a way to improve the autonomy of your phone? In this tutorial you will learn how to activate the hidden gray scale mode in order to switch the display of your smartphone screen to black and white mode. A simple and quick way to increase the usage time between each recharge..

Battery life of Android smartphones

Despite the promises made, Android phones and more specifically the Nexus are experiencing some autonomy issues . Their battery tends to discharge very quickly. If you use your phone extensively, the tip we are sharing with you today should help keep you from falling prey.

Because it is a fact known to all, smartphones hardly hold an entire day of activity without needing to be recharged. And do not think that the manufacturers are solely responsible for this situation..

User behavior also has a significant impact on battery life. Fortunately, a few small manipulations can significantly improve things and all this without reducing the performance of your device.

Screen consumption

If you are looking to increase the lifespan of your smartphone, you will have to start looking at how the screen works. This component plays a key role in the autonomy of smartphones. Special care should therefore be taken..

The first tip is to decrease the brightness of the screen . The brighter it is, the more energy it will consume. Obviously it is not always easy to find the right compromise between reading comfort and autonomy.

Switch to black and white display

Too low a brightness can cause reading difficulties, especially in direct sunlight. The reflections caused by the shiny tiles make it almost impossible to use smartphones in a very bright environment. It is therefore impossible to reduce the brightness of the screen when you are outside.

To compensate for this inconvenience, most recent smartphones have a black and white display mode . As the name suggests, this system will block the display of colors in 32 bits. The graphics chip will take less time to calculate the image and will therefore consume less battery. With significant gains in autonomy. Only problem, many phones do not offer this type of functionality. Well, not officially.
