Modern smartphones Samsung work under the control of a shell One UI, which is famous for its thoughtfulness and functionality. However, even on powerful devices, users often encounter situations where the phone starts to run slower or discharges faster. One common reason for this behavior is the accumulation of a large number of apps that continue to function after you have minimized their screen.
The operating system Android is designed so that many processes remain active in the background for quick startup. This is convenient, but sometimes leads to excessive consumption of RAM and CPU power. Device owners Galaxy S or Galaxy A often wonder how to forcefully stop these processes in order to free up system resources.
In this article we will analyze in detail all the available ways to manage background tasks. We will look at both standard methods available to every user, as well as more advanced settings for experienced owners. You will learn which applications are really worth closing, and which are better left alone for stable system operation.
Using the Menu button to quickly close
The simplest and most obvious way to manage active apps is to use the built-in task manager. On smartphones Samsung it is called by pressing a special navigation button. If you use gesture controls, you need to swipe up from the bottom and hold your finger in the center of the screen for a split second.
After the list of open windows appears, you will see all the apps that are currently running. To close a specific app, just swipe its card up or to the side. If your goal is to clear all RAM instantly, then there is a special button at the bottom of the screen.
- 🔹 Press the button
Close allto instantly stop all background processes. - 🔹 Use the icon
RAM(if it is enabled in the settings) to view the free amount of memory. - 🔹 Swipe unnecessary cards one at a time to keep important messengers active.
It is worth noting that the function Close all may not affect some system services and applications that have high priority. The system automatically protects them from closing so as not to disrupt the stability of the phone. This is normal behavior of the operating system Android.
If the "Close all" button has disappeared from the menu, go to Settings → Display → Navigation bar and make sure that the "Buttons" mode is selected and not "Gestures", or check the settings in the "App drawer" section.
Management via the menu application settings
Deeper control of background activity is carried out through system settings. This method allows you not only to minimize the app, but to completely forcefully stop its operation. This approach is necessary when the application is frozen or consumes an abnormally large amount of resources.
To access these settings, go to the Settings section of your smartphone. Next, find the item Applications, where a complete list of installed software is presented. Select from the list the app you want to stop running.
On the application information screen you will find a button Stop. Clicking on it will complete the process. The system may warn you that this may cause the app to become unstable, but this is a necessary step to resolve freezing problems.
⚠️ Attention: Do not force stop for system applications such as Samsung Members, One UI Home or Google services. This may lead to interface malfunctions or loss of data synchronization.
In the same menu, you can limit background activity without stopping completely. Go to the Battery section inside the application card and select optimization mode. This will allow the app to run, but will prevent it from running processes in the background when the screen is off.
☑️ Check before stopping the application
Developer settings to limit processes
For users who want maximum control over the system, there are hidden settings. The developer menu allows you to globally limit the number of background processes that can run simultaneously. This is a radical method that significantly affects multitasking.
To activate this mode, you need to go to Settings → Phone information → Software information. Here you need to quickly click seven times in a row on the item Build number. After this, a new section will appear in the main settings menu Developer options.
Inside this section, find the category Applications. There you will find the item Background process limit. By default, the value is “Standard limit,” but you can change it to “No more than 1 process” or “No background processes.”
| Setting the limit | Description of action | Impact on the battery |
|---|---|---|
| Standard limit | The system itself decides how many processes to keep | Balanced |
| No background processes | All applications close immediately after collapsing | Maximum savings |
| No more than 2 processes | Hard limit on the number of active tasks | High savings |
| No more than 4 processes | Moderate limitation for low-end devices | Medium saving |
Using hard restrictions may cause applications to restart every time you return to them. This increases the load on the processor at startup and can cause lag. Use these settings with caution.
How to disable Developer Mode?
To hide the developer menu, go to Settings → Apps, find the Settings app, tap Storage, and select Reset Data. This will return the settings to factory defaults, but will delete your personalizations in the settings menu.
AutoPlay feature and background activity
One of the main reasons for filling up RAM is the AutoPlay feature. Many social networks and instant messengers are configured to launch on their own immediately after turning on the phone. Devices Samsung have a built-in tool to control this behavior.
Go to Settings → Applications and find the item Autostart. Here you will see a list of all apps that have permission to start without user intervention. Disable the switches next to those applications that you do not need immediately after turning them on.
Disabling autostart does not delete the application, but only prevents it from starting on its own. You will still be able to open it manually at any time. This is an effective way to reduce the load on the system in the first minutes after turning on the screen.
- 🔸 Disable autorun for heavy games and rarely used utilities.
- 🔸 Leave autorun enabled for alarms and important instant messengers.
- 🔸 Check this list regularly after updating the system or installing new apps.
In addition to autorun, it is worth checking the background activity settings for specific groups of applications. In the section Battery and performance → Background restrictions you can put rarely used apps into "Deep Sleep" mode.
Applications in "Deep Sleep" mode never run in the background and do not send notifications until you stop them open manually.
Battery optimization as a way to manage the background
The system One UI closely links energy management with control of background processes. If an application consumes too much power in the background, the system can automatically limit its operation. You can configure these rules manually to achieve better results.
In the menu Battery select item Limit background activity. Here you can activate a feature that puts unused applications into sleep mode. The “Suspend applications in the background” option is also available, which blocks the network activity of minimized apps.
Using the power saving mode will also automatically close most background processes. When you enable this mode through the Quick Settings panel, the system aggressively ends tasks to extend battery life.
⚠️ Attention: Aggressive battery optimization may result in you not receiving call or message notifications on time. Add important contacts to the exclusion list.
For fine-tuning, go to Settings → Battery → Background restrictions → Applications in deep sleep. Adding a app to this list ensures that it will not run in the background under any circumstances, except during direct use.
Frequently asked questions (FAQ)
Is it harmful to constantly close all applications using the “Close all” button?
Yes, it can be harmful to autonomy. The operating system is Android optimized so that keeping applications in memory requires less energy than constantly restarting them. Frequent closing causes the processor to work harder each time it is launched.
Why do some applications start again immediately after closing?
This happens because the application has active services or is associated with other system processes. For example, instant messengers restore the connection to receive notifications, and music players continue playing.
How to find out which application uses the most memory in the background?
Go to Settings → Device maintenance → Memory. There you will see a list of applications sorted by the amount of RAM used in the last 3, 6 or 12 hours.
Is it possible to completely disable background work for all applications at once?
Completely disable background work for all applications without obtaining root access is impossible, as this will disrupt the operation of the system itself. However, you can set a limit for background processes in the menu for developers.
Does closing background applications affect Internet speed?
Indirectly. If background applications are actively downloading updates or synchronizing data, they occupy the communication channel. Closing them can free up bandwidth for the browser or streaming.
