Smartphone owners often encounter a situation where the device starts to work slower, and the interface responds to touches with a noticeable delay. One of the most common reasons for this behavior is that the random access memory (RAM) is full of background processes. When RAM is full, the system has to constantly unload and reload data, which leads to noticeable slowdowns.
Many users, out of habit, try to close all tabs in the recent applications menu, but this method does not always guarantee complete release of resources. In this article, we will look in detail at how to competently unload applications from Android memory, using the built-in system tools and special developer tools, to return the phone to its former speed. Differences in interfaces can be significant depending on which shell your device manufacturer uses. Whether it’s pure Android on
The differences in interfaces can be significant depending on which launcher or the shell is used by the manufacturer of your device. Whether it's pure Android on Pixel or a custom shell from Samsung, the principles of working with memory remain similar, but the paths to the settings may differ. We will look at universal methods applicable to most modern gadgets.
Why applications continue to run in the background
The modern Android operating system is designed to make maximum use of available RAM to make apps run faster. When you minimize an application, it does not close completely, but goes into the background, saving its state in cache. This allows you to instantly return to work the next time you open it without reinitializing processes.
⚠️ Attention: Forcibly stopping system services or critical applications can lead to unstable operation of the phone, failures in receiving notifications, or even rebooting the device. Proceed with caution.
However, not all applications behave in good faith. Some apps, especially social networks and instant messengers, use mechanisms autostart and continue to consume resources even when you don't need them. This phenomenon is often called memory bloat, when background processes take up space needed by active tasks.
In addition, manufacturers often pre-install many services that run in the background by default. If your device has less than 4 GB installed, the struggle for free memory becomes critical for comfortable use. Understanding exactly which processes are loading the system is the first step to optimization. RAM, the struggle for free memory becomes critical for comfortable use.

Using the recent applications menu
The most obvious and accessible way to try to close apps is to use the standard navigation menu. On most devices, it is accessed by swiping up from the bottom and holding or pressing a special touch button. Thumbnails of all running tasks are displayed here.
To close a specific application, just swipe its card left or right. If you want to free up as many resources as possible at once, many shells offer a "Close All" button or a broom icon. Clicking on this button initiates a bulk unloading of processes from active memory.
- 📱 Swipe unnecessary cards with your finger to close them individually.
- 🧹 Press the "Close all" button to clear the list at once.
- 🔄 Hold the button menu to bring up additional cleaning options on some models.
It is worth noting that this method is rather cosmetic. The Android system tends to quickly restore important applications to memory immediately after closing them through the task menu. However, for a one-time cleaning before launching a heavy game or resource-intensive application, this method is quite effective.
If the "Close All" button is missing, try long-pressing the recent applications icon in the navigation menu - on some shells this brings up a hidden cleaning menu.
Forced stop through system settings
More radical and an effective method is to use the application settings section. This method allows you not only to minimize the app, but to completely terminate its process, prohibiting the execution of any code until the next manual launch by the user.
To use this method, you need to go to Settings → Applications. In the list, find the problematic application that is consuming a lot of resources. After entering the app menu, you will see a button Stop or Forced stop. Clicking on it will cause a system warning.
Settings -> Applications -> [Select application] -> StopAfter confirming the action, the application will be completely unloaded from RAM, and all its background services will be stopped. This is especially useful for apps that are not working correctly or are frozen. However, remember that after such a stop you will no longer receive notifications from this application until you open it again.

Management through developer mode
For advanced users who want to gain maximum control over the system, there is a developer mode. This hidden menu section provides access to tools that are usually hidden from the eyes of the average user, including detailed process control.
To activate this mode, you need to go to Settings → About phone and quickly click 7 times on the item Build number. After a message appears that you have become a developer, a new section will appear in the main settings menu For developers.
In this section you can find the item Running services or Memory statistics. This displays detailed information about how much RAM each process takes. You can select any service and stop it directly. This gives a much deeper understanding of what exactly is happening in the depths of the system.
| Parameter | Description | Impact on memory |
|---|---|---|
| Limit of background processes | Limits the number of background tasks | High (frees up RAM) |
| Do not save actions | Destroys activity immediately after exit | Critical (resets everything) |
| Background check | Limits the operation of applications in the background | Medium (saves battery) |
| Window animations | Disable graphic effects | Low (speeds up response) |
⚠️ Attention: Changing the settings in developer mode, especially the “Do not save actions” item, can make using the smartphone extremely inconvenient, since each switch between screens will reset applications.
Third-party utilities for clearing memory
The store Google Play there are many applications available that promise instant acceleration of the smartphone. Popular solutions from brands such as Clean Master, CCleaner or SD Maidoffer an automated approach to clearing cache and ending processes.
These utilities work on the principle of creating a "white list" important applications and force closing everything else. They can also monitor applications that try to start automatically and block them. The use of such apps is convenient for those who do not want to understand system settings.
- 🚀 Automatic detection of “heavy” applications.
- 🛡️ Blocking autostart of unnecessary services.
- 🗑️ Cleaning residual files along with unloading memory.
However, experts often argue about the effectiveness of such “task killers”. Aggressively shutting down processes can cause the system to spend even more resources restarting them. It is better to use such tools occasionally, rather than keep them in constant active mode.
The truth about memory accelerators
Many built-in memory managers in modern versions of Android (starting from 9.0) work more efficiently than third-party applications, since they have direct access to the system core without access rights restrictions.
Limiting background activity and autorun
One of the most effective ways to prevent memory from filling up is to prevent applications from running in the background unnecessarily. In modern versions of Android, this function is built right into the settings of each application, which allows you to flexibly control the behavior of the software.
In the settings menu of a specific application, find the section Battery or Charge consumption. There you will see the option Background activity or Limit background. By switching the slider to the "Disabled" position or selecting the "Hard Limit" mode, you will prevent the application from consuming resources when the screen is off.
It is also worth paying attention to the autorun settings, which are often found in shells from Chinese manufacturers (Xiaomi, Huawei, Honor). In a special startup manager, you can uncheck those apps that you do not need immediately after turning on the phone. This will significantly reduce the load on the system in the first minutes after startup.
Limiting background activity is a preventative measure that is more effective than a one-time cleaning, as it prevents memory from filling up before it happens.
Analysis of memory consumption and diagnostics
Before starting a mass cleaning, it is useful to conduct diagnostics and understand which applications are the main consumers of resources. Built-in statistics tools allow you to see the real picture of usage RAM for the last 3 hours, 6 hours or day.
Pay attention to applications that consume a lot of memory, but which you have not used for a long time. Often such apps have memory leaks or release resources incorrectly. In such cases, the best solution would be not to simply download them, but to update them to the latest version or completely remove them and install them again.
If you notice that the memory fills up immediately after cleaning, this may indicate the presence of malware or too aggressive synchronization settings. In this case, it is recommended to check the device with an antivirus and review the list of accounts that constantly synchronize data.
Is it safe to constantly clear RAM?
No, constant forced cleaning of RAM can harm performance. Android is designed so that free memory is a waste. The system uses available RAM to cache frequently used applications so they open instantly. If you constantly reset memory, the processor has to waste energy and time re-loading data from a slower internal drive.
Why does the application appear in memory again after closing?
This is normal behavior for many system services and instant messengers. They use special mechanisms (such as Firebase Cloud Messaging or native push notification services) that have high priority and can restart the main application process to check for new messages. You can completely stop them only through “Forced Stop” or disabling notifications.
Does the weather widget affect memory usage?
Yes, active widgets, especially those that frequently update data (weather, news, exchange rates), take up space in RAM, since their process must remain active to draw the interface on the main screen. Removing unnecessary widgets can free up from 50 to 150 MB of memory.
Do you need to use antivirus applications to clean up memory?
Specialized antiviruses are not designed to clean up memory, although many of them have built-in “booster” modules. For RAM cleaning tasks, it is better to use specialized utilities or built-in system tools. An antivirus should search for threats, not manage processes.
What to do if the memory is full even after a reboot?
If immediately after a reboot less than 20-30% of the memory is free, you may have too many applications in startup or the system partition is full of data. Try entering Safe Mode (usually through the shutdown menu) to see if a third-party app is to blame. If memory is free in safe mode, remove recently installed apps.
