This post will walk you through saving battery life on your Galaxy device by stopping unused apps from running in the background. Here’s how to put unused apps to sleep on Samsung Galaxy S21 with the updated One UI 4.0 interface.

Preserving battery life in mobile devices can be carried out through many different ways. And some of these are done using certain built-in features. 

In modern Android smartphones including Samsung Galaxy S21, battery saving can be achieved by activating a number of handy features like the one that puts unused apps to sleep. Activating these features is therefore deemed among other potential tweaks to deal with massive power draining problem.

For more information about how this feature works and how to enable it on the Galaxy S21 smartphone, just keep reading.

Put Unused Apps to Sleep feature

As the name implies, Put Unused Apps is a built-in feature on the Galaxy S21 that can be accessed and managed through the Background usage limits settings.

When enabled, apps that have been idle for a long time or rarely used will be put to sleep. As a result, a significant portion of the phone’s battery life is saved and thereby allows the device to stay up throughout the day.

Apps that are put to sleep will be barred from running in the background and therefore only those apps that you use most often are permitted. 

Putting unused apps to sleep on the Galaxy S21 can be done with or without any exception.

And to give you some input on how to get this done on your Galaxy device, I’ve mapped out the actual steps as follows.

Easy Steps to Put Unused Apps to Sleep on Samsung Galaxy S21

The following steps are also applicable when putting unused apps to sleep on other Galaxy devices that are running on the latest One UI (4.0) version equivalent to Android 12.

However, the actual interface may be slightly different given that screens and menu items vary between device models and wireless service providers.

Just follow these steps whenever you’re all set to configure your device’s sleeping app settings.

Steps to Put Unused Apps to Sleep without Exception

The following steps depict the process of activating the put unused apps to sleep feature to prevent any unused apps from running in the background.

Step 1: Open the Settings app by tapping on the Settings icon from the Home or Apps screen.
Step 2: While on the main settings menu, scroll to find and then tap Battery and device care. More details about the phone’s battery usage in the previous days will show up on the next screen.
Step 3: Scroll down and then tap Background usage limits.
Step 4: On the next menu, turn on the switch next to Put unused apps to sleep. 

When the switch turns blue, the feature is turned on or enabled.

Keeping this setting will prompt the system to put all found unused or idle apps to sleep.

Steps to Put Unused Apps to Sleep with some exceptions

If your phone’s battery is draining so rapidly and you figure out which of your apps is the culprit, manually putting the errant app that you found consuming a significant amount of power or battery percentage is recommended.

Here’s how it’s done on the Galaxy S21 device:

Step 1: Open the Settings app.

Step 2: Tap Battery and device care.
Step 3: Tap Background usage limits.
Step 4: On the next menu, tap to select your preferred sleeping apps category where you would want a certain app to be listed under.
  • For example, tap on Sleeping apps and then tap the Plus (+) sign on the top-rightmost corner of the Sleeping apps menu. 
  • Select the app that you’d like to exempt and then tap Add at the bottom. You can select multiple apps at once. Just tap to mark the radio button before the name of the app from the list.
  • After adding the app(s) it will then be listed among other User-added Sleeping apps.

Just repeat the same steps should you wish to move certain apps to other categories like Deep sleeping or Never sleeping apps instead.

One UI 4.0 Sleeping Apps Categories

Apps on your Galaxy device are categorized in three groups namely sleeping apps, deep sleeping apps and never sleeping apps.

Sleeping apps are those that are currently sleeping but may run in the background when you use them again.

Deep sleeping apps are those that will never run in the background and only work when you launch them.

Never sleeping apps are those that will never turn off or sleep in the background and thus they’re all set to run anytime.

If you bump into some unexpected error after enabling the feature like when a certain app is suddenly unable to load or start after applying the recent changes, just reboot your phone. Alternatively, you can add the errant app to never sleeping apps instead.

And that’s all about preserving battery life by putting unused apps to sleep on the Galaxy S21 smartphone in the latest One UI platform.

Hope this helps!
