Then click on "Brightness Level" or any similar option.
Now tap on the Automatic Brightness switch and turn it off.
Once disabled, you can manually adjust the screen brightness by opening the quick settings menu and swiping left or right on the brightness slider as needed.
Note: When you don’t need to constantly look at your Android vietnam mobile database device’s screen, consider reducing its brightness to extend battery life. You can also switch to a darker wallpaper and screensaver to save battery life.
Tip 2: Reduce screen timeout
Screen timeout is the time it takes for the screen to turn off automatically when you are not using your device. If the timeout is longer, your device will use more battery power even if you are not actively using it. So, you can reduce the timeout to reduce battery consumption and improve the battery life of your Android phone.
Open the Settings app and tap Display or Lock Screen, depending on your device.
Then tap Screen Timeout, Sleep, or any similar setting.
