If you want your Android tablet or smartphone to stay on for more than 30 minutes, you can install an app to keep the screen on indefinitely or for a longer set time, such as an hour or two. Keeping your Android device’s screen on for extended periods can drain its battery, so it’s a good idea to keep it plugged in and charging when doing so.
It is something that we can find in the color settings and the reading mode of the phone. Do the following: Access settings. Click on “Screen”. Access “Color and reading mode”. Now in this menu we have in the first place the option ” Natural tone ” which is what we must activate so that the phone automatically calibrates the color Tap Date & time . It's near the top of the System page. Tap the Automatic date and time option. Doing so will disable automatic date and time setting, allowing you to adjust both manually. Tap Set date . This opens the calendar and allows you to select a date. You can also tap Set time .Changing the Screen Timeout will allow you to save battery in your Phone if you sometimes use the Smartphone and forget to Turn Off the screen manually. In this case, I recommend setting the option for 1 minute, grab the HUAWEI P20 Pro in your hand and let's start the changes.
