Well known to Samsung smartphone users, Grayscale mode (shades of gray) displays the entire screen of a mobile in black and white in order to reduce battery energy consumption. Do you want this exclusive feature? As we will see right away, we can now switch the screen of any Android mobile device to black and white..
Your phone drains too quickly
With the increase in the size of the screens (5 see 6 inches), the multiplication of the number of coresurs on the processors without speaking about the led flashes, the consumption of our smartphones does not stop growing. So what can be done to stop this spiral?
In terms of energy saving, almost everything has already been tried. Many manufacturers offer their homemade solutions to help us use our smartphones a little longer. But we must admit, the different battery savers very often offer the same type of service (interrupted network access, reduction of the screen brightness, freezing of applications running in the background, etc.).
Even if these software solutions can save us a few tens of additional minutes, it also imposes many restrictions on us. Once the Wi-Fi or 3G / 4G connection is cut, your Android device loses its potential enormously..
Use a black wallpaper to save battery
Nowadays, the screen remains the most energy - consuming element of a phone. The higher the definition of it, the more it will require resources and therefore consume energy. The same goes for brightness. This is why we recommend setting the brightness level as low as possible.
That said, in recent years, we have seen the emergence of a new technology called Amoled . Unlike conventional LCD, screens with this system do not use liquid crystal and therefore do not require backlighting . Each pixel on the screen itself produces its own light..
To display dark colors, Amoled screens simply turn off the pixels, thus providing better color rendering but also very good contrast (depth of blacks). Another advantage is that the Amoled is more energy efficient than the LCD.
Several tests have shown that by displaying dark interfaces on an Amoled screen this would extend the autonomy of the device. Many experts recommend that mobile users prefer black wallpapers or dark themes. With this type of image, each pixel does not need to be lit and therefore to be supplied with energy.
Android interface in black and white
Samsung has been offering a system for several years to switch the screen of its mobile in grayscale mode . A very useful feature that allows you to check your emails or view your notifications while reducing battery consumption.
Do you also want to take advantage of this system? And good news, an application offers to switch the screen of your Android smartphone to black and white automatically when your battery reaches a certain threshold. Please note, you must have super-user (root) rights on your device.
- Open the Google Play Store app
- Click on the Search icon and type Monochrome
- Press the Install button to download the app
- Then open Monochrome
- Click on the button in the middle of the main page to automatically activate black and white mode
There it's finished. Now you just have to wait until your battery is low to see your screen in black and white. Grayscale mode remains active until your device is connected to a charger.
