Smartphones have become privileged companions of our daily lives. They are omnipotent, allowing us to find our way in an unfamiliar city, entertain us for long hours, and stay in constant contact with our loved ones.
But they have a big problem: their autonomy. Since lithium-ion battery technologies are no longer evolving, our smartphones only accompany us for one day before giving up the ghost. You can optimize your battery consumption to last longer, but it’s rare for it to exceed 3 days.
It also has a negative impact on those around us: For some people, mechanically pulling your cell phone out of your pocket in the evening, even when you’re surrounded, borders on addiction.
What if there is a simple solution to both of these problems? Indeed, it is enough to switch the screen to black and white! We will explain why and how to do it on Android.
Why turn your screen to black and white on Android?
To improve the autonomy of your AMOLED smartphone
It’s no secret: AMOLED displays will gradually overwrite LCDs on mobile devices. The reason for this is very simple: they are often more contrasting and therefore more pleasing to the eye, but above all they are much less greedy for batteries.
Indeed, these completely turn off their pixels to display black, which gives a much deeper and more beautiful black than LCD screens. It is also very power-saving, so we recommend that you always have a black wallpaper on these devices.
As you can tell, turning your smartphone to black and white is the next step to take advantage of this special feature of AMOLED displays. In this mode, it consumes much less battery, allowing you to record autonomy.
To increase your concentration and stop your addiction
A second case should be brought up regarding the fact of turning your screen to black and white, as doctor James Hambling of The Atlantic explains: It will allow you to stop your attention to your smartphone to focus on the world around you.
According to him and many previous scientific analyzes, colors have an effect on our interest in any object. For example, the color red is the color that draws our attention the most.
So, a good way to “free” yourself from the potential addiction you might feel for a smartphone is to convert it to black and white. This allows us to detach ourselves from the object itself and frees our attention to engage with the world around us without the practical side of the smartphone.
In short, it’s a good solution to increase your concentration or for anyone who hears the phrase “you spend too much time on your smartphone” from someone close to you.
Turn your screen to black and white on Android
Before you can turn your screen to black and white on Android, you need to enable developer options. To do this :
- enter inside Settings
- enter inside about the phone
- find the line “Build number”
- Tap the line until a message informs you about the activation of the mod.
So all you have to do is activate the black and white mode. For him:
- enter inside Settings
- enter inside Developer Options
- Scroll down to category “Hardware Accelerated Graphics Rendering”
- choose “Simulate color space”
- To choose “Monochrome”
And there you go! Your screen is now black and white! But do not panic, because it is done in software. So it won’t damage your screen. Moreover, the system is always “in colour”: if you take a screenshot or a photo via the dedicated app, they will always be in colour. So nothing can get in the way of your experience!
