Modern smartphones Samsung Galaxy are equipped with powerful processors and capacious batteries, but even they are not immune from rapid discharge due to incorrect behavior of the installed software. Many apps continue to run in the background, consuming valuable system resources even when you are not using them. The function sleep mode (Sleeping Apps) in the One UI shell was created specifically to solve this problem, allowing you to forcefully stop the background activity of selected apps.
Activating this option becomes a real salvation for devices that work all day without recharging. Unlike completely freezing or deleting, putting to sleep does not delete your data, but only limits the ability of the application to work without your knowledge. This is especially true for rarely used utilities that you open once a week, but which constantly “hang” in RAM.
In this article we will look in detail at how to find the necessary settings in the menu of your smartphone, what are the nuances of the function on different versions of Android and how to avoid common mistakes when setting up energy saving. You will learn how sleep mode differs from deep sleep and how to set up automatic management of the list of inactive apps.
The principle of operation of the power saving function in One UI
Shell One UI from the company Samsung uses an advanced power management algorithm that analyzes the frequency of use of installed apps. When you transfer an application to sleep mode, the system stops its background operation, prohibits sending notifications and limits access to network resources until the next time the user manually launches it.
It is important to understand the difference between normal sleep and so-called “deep sleep”. In the first case, the application simply stops working in the background, but can be quickly launched again. In the second case, the app is completely unloaded from memory, and its launch may take a little longer, since the system will have to initialize the processes again.
⚠️ Attention: If you put instant messengers (WhatsApp, Telegram) or email clients into sleep mode, you will stop receiving notifications about new messages until you personally open the application.
The operating mechanism is based on strict restrictions on background processes introduced in modern versions Android. Samsung's system only provides a convenient interface for managing these restrictions, allowing the user to manually determine which apps can be trusted to run in the background, and which should go to sleep immediately after being minimized.
Use sleep mode for games and entertainment applications that you rarely use. This will save battery power without affecting the operation of important system utilities.
Manually setting the list of sleeping applications
The most reliable way to control energy consumption is to manually add unnecessary apps to a special list. This method gives you complete control over what exactly will be restricted. First, you need to get to the appropriate section of the device settings through the main menu.
The setup process is intuitive, but the path to the desired item may vary slightly depending on the firmware version. Typically, the battery settings are hidden in the device's general maintenance menu. You will need to perform the following sequence of actions:
- 📱 Open the smartphone settings and go to the
Device maintenance. - 🔋 Select
Batteryto access power settings. - ⚙️ Click on
Restrictions in the backgroundorBackground restrictions. - 💤 In the menu that opens, select the tab
Applications in sleep mode.
After going to this section, you will see a list of all installed apps. Just click on the pluses icon at the top of the screen or select the desired application from the general list to add it to the list of restrictions. The system will immediately apply the new rules for the selected software.
☑️ Check before adding to sleep
It is worth noting that some system services may not be available to add to this list. This was done by the developers Samsung intentionally to prevent critical failures in the operating system. If you cannot find the app you need in the list of available ones to add, most likely it belongs to protected system processes.
Automatic management of inactive apps
For those who do not want to manually sort through dozens of icons, the One UI settings provide a function automatic translation to sleep mode. The smartphone itself analyzes usage statistics and offers to disable background work for those applications that you have not used for a long time.
This function works on the principle of data accumulation: if you have not opened a certain game or utility for a month, the system will offer to put it to sleep. This is a convenient way to keep background processes clean without constant user intervention in the settings.
To activate this option, find in the same menu (Background restrictions) the switch named Put unused applications into sleep mode. Activating this slider will allow the system to independently make decisions about which apps should be limited.
⚠️ Attention: Automatic mode may mistakenly identify a rarely used but important application (for example, a banking client for confirmations) as unnecessary. Regularly check the list of apps put to sleep.
The time interval after which an application is considered unused is usually fixed by the system, but the operating logic can be adjusted in security updates. If you notice that the desired app has stopped sending notifications, check whether it was included in this automatic list due to an algorithm error.
Differences between sleep mode and deep sleep and optimization
Users often confuse the various energy saving modes available on smartphones Samsung Galaxy. Understanding the differences between Sleep mode, Deep sleep and general battery optimization will help you configure the device as efficiently as possible to suit your personal needs.
| Operation mode | Background activity | Notifications | Impact on battery |
|---|---|---|---|
| Active application | Full access | Work | High consumption |
| Sleep mode | Limited | Do not work | Average savings |
| Deep sleep | Completely prohibited | Do not work | Maximum savings |
| Never sleep | No restrictions | Work | Increased consumption |
Mode deep sleep is the most aggressive method of saving. Applications on this list cannot run in the background at all, and even the system's attempt to wake them up to check for updates is blocked. This is ideal for apps that you only need when you run them yourself.
At the same time, the usual battery optimization, available through the maintenance menu, works more smoothly. It analyzes usage patterns over the last 7 days and makes recommendations, but does not enforce hard limits without user confirmation. Sleep mode acts preventively and constantly.
Technical details of the operation of Daemon processes
The DeviceCare Daemon system service monitors the time of the last launch of the APK package. If the timer exceeds a threshold value (usually 30 days for auto-sleep), the packet is marked with the restricted flag, which blocks the BroadcastReceiver from logging for system events.
Exceptions and the list of applications that never sleep
In addition to the list of those who should sleep, there is also a reverse list - applications that never translated to sleep mode. This is a critical section of settings for apps that need to work around the clock, regardless of whether you are using them right now or not.
Activity trackers, smart home applications, third-party alarm clocks, and call recording apps are usually added here. If such an application goes into sleep mode, it will cease to perform its functions, which can lead to serious inconvenience or loss of important data.
Adding to the exclusion list is done in the same menu Restrictions in the background, but on the tab Applications that never sleep. The process is similar to adding to sleep: you select the desired app from the general list, and the system removes all background activity restrictions from it.
- 🚫 Do not add games or video players to this list - this is a pointless waste battery life.
- ✅ Be sure to add instant messengers here if instant message delivery is important to you.
- 🏠 Add applications for smart home control (SmartThings, Yandex, etc.).
Remember that the list of exceptions takes precedence over all other energy saving settings. Even if the maximum power saving mode is enabled, applications from this list will continue to operate normally, ignoring general system limitations.
The "Never Sleep" list is the main tool for ensuring stable operation of background services. An error in setting this list may result in the alarm not working or the data not being synchronized.
Possible problems and solutions
Sometimes users are faced with a situation where the settings are not saved or the application spontaneously exits sleep mode. Most often, this is due to the fact that the application itself requests permission to run in the background every time it is launched, ignoring One UI system restrictions.
Another common problem is the lack of a menu item on older versions of the firmware or on devices released for other markets. In such cases, the interface may be different and features may be named differently, such as "Background Restrictions" without explicitly mentioning sleep.
If you've changed the settings but your battery is still draining quickly, try clearing the cache of the problematic app before putting it to sleep. Sometimes accumulated temporary files interfere with the correct application of new energy saving rules set by the user.
⚠️ Attention: The settings interface may vary depending on the version of One UI (4.0, 5.0, 6.0) and regional firmware. If you do not find the described items, use the search in the settings by entering the query “sleeping” or “battery”.
In rare cases, resetting the battery settings through the recovery menu helps, but this is a last resort. Usually, it is enough to simply remove the application from the sleep list, reboot the smartphone and add it back so that the system daemon correctly registers new restrictions.
Hidden configuration via ADB
For advanced users, it is possible to force packages into standby mode via the ADB shell pm set-background-restriction commands, however, this requires root access or USB debugging and is not recommended for ordinary users users.
Frequently asked questions (FAQ)
Will the application be deleted if I put it to sleep?
No, putting it to sleep does not affect the availability of the application on your device. The app remains installed, all your data, logins and settings are saved in full. The only thing that changes is its ability to work in the background without your participation.
Can Samsung system applications be put to sleep?
Most critical system applications are protected from being put into sleep mode. You just won't find them in the list of available ones to add. This is done to ensure that users do not accidentally disable important services that are responsible for the operation of the phone, network or interface.
Why did the application disappear from the sleep list after the update?
When updating the firmware or the application itself, the restriction settings may be reset to default values. The system may decide that after updating the app requires re-checking access rights. You will need to add it to the list of restrictions again.
Does sleep mode affect the launch speed of the application?
Yes, when you first launch after being in sleep mode, the application may open 1-2 seconds longer than usual. This time is required for the system to allocate resources and initialize processes that have been completely stopped.
How can you learn how much battery an application saved in sleep mode?
The section Settings → Battery has usage statistics. There you can see the discharge graph. However, the system does not show a direct figure for savings from a specific sleep mode, but you can notice a decrease in overall background consumption per day.
