Many Android users have been curious about what it means to 'put an app to sleep'. This feature is a battery-saving technique that prevents apps from running in the background and consuming power. By putting an app to sleep, users can conserve battery life and reduce data usage. This is particularly useful for apps that are not frequently used, such as the calculator app. However, it can also be annoying when important notifications are missed due to apps being in sleep mode. Users can customize their preferences by specifying apps that they never want to sleep in the background, as well as those that can be put to sleep when idle. This functionality is available on various Android devices, including Samsung Galaxy phones and tablets, and can be accessed through the device's settings.

What You'll Learn
Putting apps to sleep saves battery life
If you constantly switch between apps on your Android device, your battery will drain quickly. To save battery life, you can put some of your apps to sleep. This will prevent them from running in the background, allowing you to focus on the apps you use most often. You can always change the settings later if you need to start using certain apps again.
There are several options for putting your apps to sleep, depending on how often you use them. For example, if you rarely use the Calculator app, you can set it to "Deep sleeping apps" to prevent it from draining your battery. To do this, navigate to Settings, tap Battery and device care, tap Battery, then tap Background usage limits. You can also choose to "Put unused apps to sleep", which will automatically put an app to sleep if you haven't used it in a while.
Another option is to use the "ALWAYS SLEEPING APPS" setting, which allows you to specify apps that you never want running in the background. For example, you may have a flashlight app that uses the LED camera flash, which you only need occasionally. By putting this app to sleep, it will only consume power when you need it.
Putting apps to sleep can also help if your phone is slowing down or becoming unresponsive due to many apps working in the background. By putting some apps to sleep, you can efficiently allocate resources, allowing your phone to upgrade its overall capacity and responsiveness.
While putting apps to sleep can save battery life, it can also cause issues with delayed notifications. Android offers ways to counter this behavior, such as the battery optimization setting, which allows you to fix notification issues and ensure that important apps are not put to sleep.

Deep sleep stops apps running in the background
On Android devices, the 'sleep mode' refers to the process of putting certain apps to sleep to prevent them from running in the background. This is done to conserve battery life and optimise the phone's performance. While this can be helpful for saving battery, it can also be annoying when important notifications are missed.
Deep sleep for apps is a feature on Android devices that allows users to put certain apps into a state where they will not run in the background. These apps will only work when opened manually and will not consume any battery life when not in use. This is particularly useful for apps that are rarely used, such as the Calculator app.
To enable deep sleep for specific apps, users can navigate to the device's settings and tap on "Battery and device care". From there, users can select "Battery" and then "Background usage limits". This will allow users to put unused apps to sleep, meaning they will not run in the background until manually opened.
It is important to note that some apps, such as companion apps for smartwatches or fitness trackers, may require background syncing to function properly. In such cases, users can prevent these apps from sleeping in the background by locking them in the multitasking overview. Additionally, Samsung devices offer additional settings to control sleeping background apps, which can be accessed through the "Battery and device care" menu.
By utilising the deep sleep feature for select apps, Android users can achieve a balance between optimising battery life and ensuring that important apps continue to run in the background. It is always possible to switch the settings later if different preferences arise.

Sleeping apps don't send notifications
On Android devices, users can put apps to sleep to save battery life. This prevents the apps from running in the background, allowing users to focus on frequently used apps. While this feature is useful for battery preservation, it can cause a delay in receiving notifications from the sleeping apps.
Deep sleeping apps will never run in the background and will only work when manually opened by the user. However, some apps with real-time notifications, such as Telegram, may continue to send notifications even when placed in the deep sleeping apps category. This may be due to certain permissions within the app settings, such as "prevent phone sleep mode," which can prevent the app from going into sleep mode even when closed from the Recent Apps tab.
To prevent apps from sleeping in the background on Android devices, users can adjust the battery optimization settings. By locating the desired app on the home screen or launcher, accessing the long press menu, and selecting the "Optimized" option, users can ensure that the app runs normally and receives timely notifications.
Additionally, Samsung devices offer an alternative method through the "Modes and Routines" app, which can supersede the OS-level battery optimization settings. It is important to configure both the Android and Samsung settings to ensure that the desired apps remain active and receive notifications.
By understanding and customizing the sleeping app settings, users can balance battery optimization and timely notifications on their Android devices.

Battery optimisation settings
Android devices typically force low-priority apps to go to sleep to save battery life and optimise performance. While this is useful for preserving battery life, it can be frustrating if you miss important notifications.
You can adjust these settings by navigating to Settings, then Battery and device care, and then tapping Battery. From there, you can tap Background usage limits and choose from the following options:
- Sleeping apps: These apps may run in the background if you start using them.
- Deep sleeping apps: These apps will never run in the background and will only work when you open them.
- Never sleeping apps: These apps will never turn off or sleep in the background.
You can also add or remove individual apps from each of these categories. For example, if you rarely use the Calculator app, you can set it to Deep sleeping apps so it doesn't drain any battery life.
On some devices, you can also access the Battery optimisation settings by going to Settings, then Apps, then App battery usage, and then selecting the desired app. From there, you can tap Allow background usage.
It's worth noting that some third-party apps promise to optimise battery use, but they may revoke background permissions for apps that need them to function correctly. Additionally, Samsung devices offer another way to control sleeping background apps that can supersede the OS-level battery optimisation setting.
