How to prevent the mobile screen from turning off automatically on Android

26 mayo, 2021

There are few things more annoying than when you are paying attention to something on your mobile and the screen turns off by itself because you haven’t touched it for a long time. And, if you don’t have a Smart Lock or similar, you can enter the PIN code again or use your fingerprint.

To solve it we will see how can you keep the screen of your Android mobile on, first by changing the configuration in Android and from the developer settings, and then show you how to do it with an application so that it is easier for you to switch between the always-on screen mode and the normal mode.

Increase the waiting time

Ideally the mobile would keep the screen on until you turn it off, like the TV, but there is a problem: is the component that drains the battery the most. The way to tackle this problem that most operating systems have found is to establish a timeout after which the screen will turn off by itself. On Android, this timeout is generally 30 seconds.

If you don’t touch the screen during the waiting time, it turns itself off.

That is, Android keeps the screen on even if you do not touch it for those 30 seconds, although from second 20 the brightness is reduced. If at any time you touch the screen, the account will start over from scratch. This setting can be changed in the settings, and is sometimes called wait time or suspend time.

Seven apps that are draining your Android battery

To change the waiting time you need to open the Android settings application and then go to Screen section. It should appear there, although the setting in question may change places in other customization layers. If you have trouble finding the setting, use the search box within the settings.

Waiting time

The configurations may vary from one mobile to another, but generally you can choose a range that goes from 15 seconds to 30 minutes. Choose the one that convinces you the most, although if you choose a high figure, remember to turn off the screen manually, because not only does it drain the battery quickly, but it can burn the image.

Keep screen on while charging

Android’s normal setting doesn’t allow you to keep the screen always on, but you can. from developer settings, at least while the mobile is plugged in. These settings are hidden by default, so you need to turn them on first. The way to do it has not changed for years: go to the Android Settings, section Device Information, Y tap seven times on the build number.


A text tells you that the options for developers are activated, and to enter them you need to retrace your steps, in Settings, this time entering System. Here are the Developer options, and one of the first on the list is Always-on display when charging.

Always reignited

It is not possible to activate this option without charging the device, so if that is what interests you, you need a third-party application like the one we are going to see next.

Use Caffeine to keep the screen on

If none of the previous sections solves the ballot, you will always have Google Play. There are countless applications whose sole purpose is to allow you to keep the screen on. One of the most up-to-date is Caffeine, which can be used as a quick adjustment on mobiles with Android Nougat or higher.



When you open Caffeine, its settings window will be shown to you, although the way to use it is through the quick settings of Android. Namely, you need to add your quick setting first, by displaying the notification panel and tapping on the pencil icon (note: the method may be slightly different in customization layers). Then drag its icon, which is a cup of coffee.

Caffeine You must drag the Caffeine icon to its position in the quick settings

After adding the button, display the notification panel and, in the quick settings, tap on the Caffeine icon to activate it. The default mode will keep the screen active for a minute, but tapping on this text will alternate between different settings, until finally the infinity symbol appears.


Now yes, the screen will remain active indefinitely and regardless of whether the mobile is charging or not. If at any time you want the mobile to behave as usual again, that is, for the screen to turn off by itself, you just have to retrace your steps and disable it in quick settings from Android.
