Modern operating system-based smartphones Android are designed so that applications remain active even after you minimize them or press the Home button. This is done so that when restarted, the app opens instantly, without wasting processor resources on re-initialization. However, many users notice that over time the device begins to work slower, quickly discharges or heats up, and intuitively try to forcefully stop all processes.
In fact, the operating system itself perfectly manages resource allocation, unloading unnecessary apps from RAM (RAM) as needed. However, there are situations when a particular application is frozen, consuming an abnormally large amount of energy, or simply interfering with your work, and then there is an urgent need to close it manually. In this guide, we will look in detail at all the ways to manage active processes, from standard gestures to advanced developer tools.
Understanding how task manager works in your firmware version will help you not only free up memory, but also extend the battery life of your gadget. We will look at the differences between standard shells from Samsung, Xiaomi, OnePlus and pure Android, since the logic of the buttons and menus may differ significantly.
Standard gestures and multitasking menu
The most An obvious and common way to close applications is through the multitasking interface. Depending on the navigation method you choose (three buttons at the bottom of the screen or gesture controls), this menu is accessed differently. If you are using classic navigation, you need to click on the square button or the button with three stripes, usually located to the right of the Home button.
When using gesture navigation, which has become standard in modern versions Android 10 and newer, you need to swipe from the bottom up and hold your finger in the center of the screen for a split second. A carousel of running applications will open, where each of them is presented as a separate card or tile. This is where the main management of active sessions occurs.
To close one specific application, find its card in the list and swipe it up (or to the side, depending on the device model). If you want to close everything at once, look for a button that says “Close All,” “Clear,” or a broom icon. Please note that on some smartphones with shells like MIUI or ColorOS this button may be hidden at the bottom of the screen and look like a cross.
⚠️ Attention: Mass closing of all applications at once can lead to the system starting to reload the most important services, which will cause increased consumption in the first minutes after cleaning battery charge and processor load.
Users often wonder: does it make sense to do this regularly? For most scenarios, the answer is no. The system Android is designed so that empty RAM is considered wasted. Applications that you have minimized are in a “frozen” state and consume almost no resources until you return to them.
Application settings and forced stop
Sometimes a standard swipe is not enough. There are times when an app continues to run in the background, play sound, or use geolocation even after you remove it from the multitasking menu. In such situations, a more radical method is required - the “Forced Stop” function. This tool completely kills the application process, not giving it a chance to restart until you open it yourself.
To use this function, you need to go to the main settings of your smartphone. Find the section Applications or Applications and notifications. In the list of installed apps, select the one that causes you suspicions or problems. Next, scroll down the page to the Stop or Forced stopbutton. The system will warn you that the application may not work correctly after such an action - confirm the operation.
This method is especially effective for “heavy” apps such as navigators, social networks or games that can leave background services active. However, it is worth remembering that it is better not to stop system applications, such as Google Play Services or shell components, as this can lead to unstable operation of the entire interface.
In some cases, the “Stop” button may be inactive (gray). This means that the application is not currently running or is a critical system process that the operating system is protecting from user intervention. Attempts to bypass this protection without root access usually unsuccessful and are not recommended.
If the application constantly restarts itself after stopping, check its permissions. Often the culprit is background permissions or location access that need to be revoked manually.
Using the Developer Menu
For advanced users who want maximum control over how to quickly close background apps on Android, there is a hidden "Developer" menu. It is disabled by default to prevent inexperienced users from accidentally changing critical system settings. Activating this menu provides access to detailed process management settings.
To unlock this section, go to Settings → About phone (or About device). Find the item Build number and quickly click on it 7 times in a row. You will see a notification stating that you are now a developer. After this, a new item will appear in the main settings menu - System → For developers.
Inside this menu we are interested in the section related to applications. Here you can find the option Do not save actions (Don't keep activities). If you enable this switch, the system will destroy each application as soon as you leave its screen. This is a radical method that is guaranteed to free up memory, but makes multitasking impossible - when you return to the app, it will be loaded from scratch.
A setting is also available here Limit of background processes. You can limit the number of applications that can remain in memory, for example to 2 or 4. As soon as you launch the fifth application, the oldest one on the list will be automatically closed. This is a useful feature for devices with a small amount of RAM (2-3 GB), but on powerful smartphones it can only interfere with comfortable work.
☑️ Activating developer mode
⚠️ Attention: Changing settings in the developer menu may lead to unpredictable system behavior, notification failures and rapid battery drain. Use these tools only if you understand the consequences.
Another interesting feature in this section is Process statistics. It allows you to see which applications are consuming the most resources in real time and terminate them directly from that list. This is a more visual analogue of the task manager on a computer.
Third-party utilities and task managers
In the store Google Play there are thousands of applications that promise to “speed up your phone” and “clean up memory”. Popular solutions like Greenify, CCleaner or built-in “Accelerators” from smartphone manufacturers work on a similar principle: they scan RAM and forcefully close selected processes.
However, the effectiveness of such apps in modern versions Android (starting from 8.0 and higher) has significantly decreased. The operating system has learned to tightly control third-party applications, preventing them from arbitrarily closing other processes without special permission to access usage statistics. Often such utilities themselves become a source of load, running in the background and checking the memory status every few minutes.
However, some specialized tools can be useful. For example, Greenify allows you to “put to sleep” applications, preventing them from running in the background until you open them yourself. This is not exactly the same as closing, but has a similar resource-saving effect. Other applications can provide widgets on the desktop to quickly clear the cache or memory with one click.
| Type of utility | Principle of operation | Efficiency on Android 12+ | Risks |
|---|---|---|---|
| Built-in “Cleaner” | Has system privileges | High | Minimum |
| Third-party cleaner | Requesting access rights | Medium/Low | Intrusive advertising |
| Greenify | Launch blocking | High (to save money) | Notification delay |
| Memory widget | Visualization + cleaning | Low | Extra processes |
If you decide to use third-party software, Choose only proven solutions with high ratings and avoid apps that require suspicious permissions or promise to “increase speed by 5 times.” Most often, this is a marketing ploy that has no technical basis.
Why do antiviruses also clean memory?
Many antivirus suites include optimization modules. They can close applications, but their main task is security, so they waste resources on scanning, which can negate the benefit of clearing memory.
Features of working in various shells
Smartphone manufacturers are actively modifying the clean one by adding their own proprietary shells. This affects how the application closing feature is implemented. Knowing these nuances will help you quickly find the right buttons on your specific device. Android, adding your own branded shells. This affects how the application closing feature is implemented. Knowing these nuances will help you quickly find the right buttons on your specific device.
In devices Samsung with a shell One UI the multitasking menu allows you not only to close applications with a swipe, but also to pin important apps. A pinned app cannot be closed by accident or with the Close All button until you unpin it. To do this, you need to click on the application icon at the top of the card and select the appropriate item.
Smartphones Xiaomi, Redmi and POCO running MIUI or HyperOS often have a built-in deep cleaner. When you swipe up to call up the multitasking menu, a cross may appear at the bottom, and when you click on it, the system not only closes applications, but also offers to clear the cache. There is also a “Lock” function that locks the application in memory, protecting it from being cleared.
On devices OnePlus and Realme (shells OxygenOS and Realme UI) the logic is close to pure Android, but often a “Memory Extension” function is added, which uses part of the permanent storage as virtual RAM. Closing applications on such devices may work slightly differently due to the way this virtual memory is managed.
In a pure Android (series Google Pixel, Moto), the interface is as minimalist as possible. There are no additional cache clear buttons in the multitasking menu, and the system relies solely on its process unloading algorithms. The user is provided with only the basic functionality of swipes.
Branded shells often add functions to block applications from closing. If you cannot close the app in the usual way, check if there is a “lock” or a pin icon on it.
⚠️ Attention: Interfaces are updated with each firmware version. The location of the buttons and the names of menu items may differ from those described above. Always focus on the logic of the icons, and not just the text.
Frequent questions and problems when closing applications
Even understanding the theory, users often encounter practical difficulties. Why does the application open again immediately after closing? Why doesn't the Stop button work? These issues are related to the architecture of modern mobile operating systems and the protective mechanisms of manufacturers.
Many instant messengers and social networks use special services to deliver push notifications. Even if you close the main application, the system service will continue to run so that you can receive the message. When you try to open the application again, it will quickly pick up data from this service and restore its appearance, creating the illusion that it was not closed at all.
In addition, some applications have the right to autorun. This permission allows them to start immediately after turning on the screen or rebooting the phone. To really get rid of such an application, you need not just close it, but disable autostart in the battery settings or in a special permissions section.
Sometimes users complain that after closing all applications, the phone starts to slow down even more. This is a normal reaction: the processor has to reload the system kernel, Google services, launcher and other basic components that were unloaded. The peak load occurs precisely in the first seconds after complete cleaning.
Is it harmful to constantly close all applications?
Yes, this can be harmful to battery life. The system spends more energy re-launching applications than storing them frozen in RAM. Do a full cleanup only if a particular application is frozen or is behaving incorrectly.
Why won’t the application close with a swipe?
The application is likely set to “Pin” or “Lock” in the multitasking menu. Look for a lock or pin icon on the app card and disable it. Also, some system processes are protected from being closed by the user.
How to close an application that is not responding?
If swiping does not work, use the “For Developers” menu → “Process Statistics” and end the process there. As a last resort, rebooting the device or forcing a stop through the main Settings → Applications will help.
Does closing the background speed up games?
Insignificant. If you have little free RAM (less than 10-15%), then closing unnecessary applications before starting a heavy game can prevent the game from crashing. If there is a lot of memory (6-8 GB or more), the system itself will cope with the distribution of resources without your intervention.
Is it possible to configure automatic closing of applications?
There is no direct standard tool for this in pure Android. However, many shells (Xiaomi, Samsung) have "App Sleep" or "Auto Clean" functions, which can be configured in the battery section. Third-party applications can also emulate this feature.
