How to disable screen timeout on Android devices: A step-by-step guide

Knowing how to disable screen timeout on Android is important for the uninterrupted operation of corporate devices, optimizing workflows, and maintaining a consistent user experience across a managed device fleet. We are surrounded by screens and devices all the time, and sometimes require the screen to remain on while we juggle between tasks and devices. 

With an easy setting, we can change the duration for our screen to remain active, depending on our needs. The problem arises when the setting changes, and you have to reset the screen timeout. It gets frustrating, doesn’t it? The setting can be reversed in a blink with a system update or when overridden by another application. 

The way out of this problem is to know the different methods of changing the screen timeout duration or disabling it altogether. Let’s see how to do this. 

What is screen timeout on Android? 

Screen timeout is a feature that automatically turns off the display after a certain period of device inactivity. It determines how long the screen will stay on when the device is idle. 

This feature helps reduce battery usage and improves overall security by preventing unauthorized access when the device is not in use. 

How to disable screen timeout on Android devices 

Most of the Android devices have a pre-defined screen timeout setting. You can easily change the duration by following the steps given below:  

• Step 1: Open the Settings menu on your device.
• Step 2: Navigate to Display and select it. 
• Step 3: Choose the screen timeout option from the list (sometimes it is labelled “Sleep” or “ Display timeout”). 
• Step 4: Here, you will see timeout durations ranging from 15 seconds to 30 minutes. Select your preferred duration. 

Tips for choosing the right screen timeout duration 

Choosing the right screen timeout duration depends on your preference, usage, activities performed, and environment. 

1. Short-duration timeouts (15-30 seconds): It is recommended for users who want to preserve battery life. Shorter duration offers a quick security level by locking the device within seconds.

2. Medium-duration timeouts (1-5 minutes): This is recommended for daily usage for users who use multiple devices. It allows a longer window to switch between devices, reducing the hassle of unlocking again. 

3. Long-duration timeouts (10 minutes or more): Used for extensive use of the device, such as reading, during a presentation, or the device being used as a reference screen. 

4. “Never” timeout: This setting is not usually available in Android devices. Use it wisely, as it quickly drains the battery and may lead to security issues if you forget to lock the device. Primarily used for digital signage or kiosk devices, or during critical troubleshooting, where the device must remain on. 

2 methods to disable screen timeout on Android devices

Android devices usually don’t have the disable screen timeout feature. So, how to keep your screen from turning off? Here are two methods to try out:

Method 1: Accessing the developer options on the device

First, you have to enable the developer options on your device, then you can access the settings.

• Step 1: Open the Settings menu on your device. 
• Step 2: Select “About phone” or “About device” from the menu list. 
• Step 3: Locate “Build number” from the list and tap it seven times quickly. You may have to enter your device’s PIN or password. This step enables the Developer options.
• Step 4: Go back to the main settings and select “Display.”
• Step 5: Find and select the “Screen timeout” or “Sleep” option from the option list. 
• Step 6: Here, select the “Never” option for the timeout duration, which is now available. 

If it is not available, then follow the next technical method to disable screen timeout. 

Method 2: Android Debug Bridge 

This is a more technical option, where you have to execute command lines. This method allows you to set a very high timeout duration that has a similar “never” timeout effect. However, it does not enable the “never” timeout options. 

• Step 1: Enable the developer options on the device, then enable USB Debugging. 
• Step 2: Plug your device into a computer or laptop that has the Android Debug Bridge (ADB) setup.
• Step 3: Verify the connection by running the command: adb devices, and it should list your device’s serial number. 
• Step 4: Execute another command line setting a very high screen timeout limit:
  adb shell settings put system screen_off_timeout 2147483647 

The highest value allowed is 2147483647, which is approximately 596 hours or almost 25 days. This lets you have an unlimited timeout effect, but not truly.  

Limitations of manually disabling screen timeout 

1. Technically intensive and user-dependent 

Both suggested methods (Developer Options or ADB) require technical knowledge. These can be challenging for a non-tech-savvy person, which can lead to more configuration errors, or they may not find the right setting altogether.

2. “Never” option is not guaranteed

• Accessing the Developer Option does not guarantee the availability of the “Never” timeout option.
• The availability is dependent on:
  • Android version
  • OEM implementation
  • Device policy restrictions

3. ADB does not provide a true “Never” timeout 

By using ADB, you can only set a very high timeout value, which still can be reversed or may not work in different cases, such as:

• May reset after a reboot. 
• Can be overridden by a system update. 
• May not bypass the new system policy. 

4. Not scalable for organizations 

For enterprises, implementing these methods on a large fleet of devices is not a viable option. The possibility of operational failures and human error also increases. 

5. Risk of battery and device damage 

Several issues, such as battery health degradation and device thermal stress, may remain unidentified without a centralized device health management system monitoring them.

Disable screen timeout on Android with Scalefusion UEM 

The two screen timeout methods (Developer options and ADB) are good options for a personal device or a few more. However, consider doing the same manual work for hundreds, if not thousands, of enterprise devices. It will quickly become time-consuming, difficult to manage, and inconsistent. 

In this scenario, a Unified Endpoint Management solution like Scalefusion helps you apply customized policies to a larger fleet of devices with ease. 

Scalefusion UEM simplifies screen timeout management. It gives you options to select a particular timeout duration, customize the duration, or you can also choose to keep the screens always on for all your corporate devices. The solution eliminates the need for manual configuration, enabling you to enforce these policies remotely from one location for all the devices. 

Now, let’s look at the steps to learn how to disable screen timeout on Android devices using Scalefusion:

Steps to disable screen timeout: 

Step 1: On the Scalefusion dashboard, go to Device Profile & Policies, then select Device Profiles.

Step 2: Create a new device profile or select an already existing one. In this case, we will create a new device profile. 

Step 3: Select Create New Profile.

Step 4: Select the Kiosk/Agent option. Enter a name for the profile and an exit passcode. Click the Submit button to save. 

Step 5: In the profile creator view, navigate to the Restrictions section. 

Step 6: In the Restrictions section, choose the Display option from the upper row. 

Step 7: Navigate to the Screen Time Out Settings. Here, you can use these settings to keep the screen always on or specify a duration of inactivity after which the screen will go to sleep.

i. Pre-Defined Settings: From the dropdown menu, select the time duration from 15 seconds to 30 minutes. Now your screen will remain active for the set duration when the device is inactive. 

• Keep Screen Always On: This option enables you to keep your screen always on. 

• Keep Screen Always On While Charging: This option prevents screen timeouts when the device is plugged into a charger. It is useful for IT teams during software updates, provisioning, or maintenance tasks that require a constant power supply and an uninterrupted screen display. 

ii. Custom Duration: You can set your preferred timeout duration (in minutes) other than the specified ones. This helps you set the timeout duration as per your requirements.

Now, your screen will remain on even when the device is inactive. 

Beyond screen timeout settings, Scalefusion UEM enables you to manage devices, enforce organization-wide policies, and maintain the entire configuration lifecycle, all from a single dashboard.
