Many smartphone users mistakenly believe that simply minimizing a app to the background is equivalent to turning it off completely. In fact, when you press the Home button or swipe up, the app only goes into background activitystate, continuing to consume CPU resources and RAM. This fundamental difference in architecture Android often causes the battery to drain quickly and the device to slow down throughout the day.
In order to truly free up system resources, you must force stop or gracefully terminate the process through the multitasking menu. In this article, we'll take a closer look at how the operating system works, explain why standard minimization isn't always effective, and provide step-by-step guide for different firmware versions.
Understanding how to manage background processes is key to keeping your gadget's performance high. We will consider not only standard methods available to every user, but also the nuances associated with aggressive memory optimization in modern shells from Xiaomi, Samsung and other manufacturers.
Fundamental differences between collapsing and completely closing
When you move from one application to another, the operating system does not kill the previous process, but only freezes its state in RAM. This is done so that when you reopen the app, it starts instantly, without the need to reinitialize all components. However, this behavior has its price - RAM is gradually filled with the cache and data of hung processes.
Unlike minimizing, completely closing the application initiates a command to the system to release all allocated resources. This includes unloading code from RAM, stopping all associated services and closing network connections. If an application continues to run in the background without your knowledge, it may use geolocation or the microphone, which critically affects battery life.
⚠️ Warning: Completely closing system applications (such as Phone, Messages, or Settings) may cause the interface to become unstable and the appearance of errors in the system.
Modern versions of Android, starting from Android 10 and higher, have become much more aggressive in managing background tasks independently. However, manual control remains a necessary tool for heavy games or apps with poor optimization that are prone to “memory leaks.”
Standard methods of closing through the multitasking menu
The most obvious and accessible way to manage running apps is to use the built-in task manager. Depending on the type of navigation you have set up on your device (button or gesture), this menu is accessed differently. On devices with classic buttons, you must press the key with a square or three lines, usually located to the right of the Home button.
If you are using a modern one gesture navigation, then to call up the list of recent applications you need to swipe up from the bottom edge of the screen and hold your finger at the center point for a split second. A carousel of windows will open, with each window representing a running application. To close a specific instance, you need to swipe its card up or to the side, depending on the shell version.
It is important to understand that simply swiping the card in some custom firmware (for example, MIUI or OneUI) may not kill the process completely, but only hide it from the visual list. To guarantee the completion of work, you often need to click the “Clear all” button or use the special trash icon that appears in the multitasking interface.
☑️ Correct cleaning through the task menu
Forced stop through system settings
When standard swiping does not help and the application continues to hang in memory or consume charge, you need to use a deeper management tool - the application settings menu. This method ensures that all services associated with a particular app are completely stopped and its temporary data is reset from RAM.
To perform this operation, go to the section Settings → Applications → Manage applications. In the list that opens, find the desired app and tap on its name. On the application information screen, you will see a button Stop or Force stop. Clicking on it will cause a system warning confirming that the application will be completely closed.
This method is especially effective for “heavy” apps that behave incorrectly in the background. However, it is worth remembering that after such a stop, the application will start again only with your manual intervention, since all background triggers will be deactivated until the next start.
⚠️ Attention: The settings menu interface may differ on smartphones of different brands. On some models, the stop button is hidden under the additional menu (three dots in the corner of the screen).
Using the forced stop function is also useful when the app freezes. If the application interface does not respond to taps, this method allows you to “kill” the process without having to restart the entire smartphone, saving you time.
If the Stop button is grayed out, this means that the application is a system component necessary for Android to work and cannot be closed using standard means.
Using power saving modes to control the background
One of the most effective ways to automatically manage background processes is to use built-in energy saving modes. Activating this mode changes the operating system policy from prioritizing performance to prioritizing battery saving.
When the mode is enabled Energy Saving the system begins to aggressively limit the background activity of applications. This means that apps that you minimized will stop much faster than in normal mode. Some shells, such as Samsung One UI or Xiaomi MIUI, allow you to configure a list of applications that will never go to sleep, even when power saving is active.
To configure these settings, go to Settings → Battery → Energy saving modes. Here you can select the level of restrictions. In the “Maximum Savings” mode, not only background work is often blocked, but also data synchronization, which actually turns the smartphone into a device only for calls and basic tasks.
| Operating mode | Influence on background | Synchronization | Visual effects |
|---|---|---|---|
| Normal | Minimum restrictions | Full | Enabled |
| Optimized | Moderate restrictions | Full | Included |
| Saving | Strict restrictions | Scheduled | Limited |
| Max. saving | Full background stop | Disabled | Minimum |
Using these modes allows you not to think about manually closing applications, since the system takes over this control. However, you should be prepared for the fact that notifications from instant messengers may arrive with a delay.
Energy saving modes are the best way to automatically “close” applications in the background without manual intervention, sacrificing the speed of receiving notifications.
Setting background activity restrictions for specific apps
In modern versions Android has a flexible battery management system for each installed application separately. This allows you to manually tell the system exactly what it should do with a specific app after you minimize it.
Go to the settings of a specific application through Settings → Applications and find the section Battery or Battery consumption. Here you will be asked to choose one of several behavior options. Selecting “Limited” or “Hard Restriction” will force the system to close the application as soon as you leave its screen.
This feature is especially useful for apps that you use infrequently, but which tend to consume excessive resources. For example, social networks or news aggregators often update your feed in the background, even if you don't need them right now. Setting a restriction will prevent this activity.
⚠️ Attention: Setting strict restrictions for instant messengers (Telegram, WhatsApp) may result in you not receiving a message until you manually open the application.
It is also worth paying attention to the “Adaptive Battery Mode” function, which is available in pure Android and many shells. If it is turned on, the system itself learns your habits over time and automatically limits those applications that you rarely use.
What is “Deep Sleep” in Samsung?
Samsung shells have a “Deep Sleeping Apps” function. Apps added to this list will never run in the background until you reopen them. This is analogous to completely blocking background activity.
Problems and myths about constantly closing applications
There is a common myth that constantly closing all applications in a row extends battery life and speeds up the smartphone. In fact, this is not always the case. The Android operating system is designed to keep frequently used apps in memory, since cold starting them again requires more processor power than keeping them in the background.
If you constantly close everything, you force the processor and storage to work harder each time you start it again. This creates a paradoxical situation: trying to save resources, you increase the load on the hardware of the device. Flash memory work harder with each new start. This creates a paradoxical situation: while trying to save resources, you increase the load on the device’s hardware. Caching data in RAM is a normal and useful process.
Closing applications manually makes sense only in specific cases: if the app hangs if it is clearly eating up the battery (as can be seen in the statistics), or if you need maximum performance for the game. In other cases, entrust memory management to the system algorithms.
In addition, the frequent use of third-party “cleaners” and “accelerators” often does more harm than good. These applications themselves run in the background, show ads and constantly restart system services, which are immediately launched again at the request of the system.
Instead of installing “cleaners”, use the built-in “Device Care” tool or a similar one in the settings of your smartphone - it is safer and more efficient.
Is it harmful to close applications through the multitasking menu every evening?
Daily completely clearing all applications before bed does not cause critical harm, but it does not bring much benefit either. The system itself will unload unnecessary things when there is insufficient memory. However, this can be a useful habit to clear the accumulated visual garbage in the task list.
Why does the application start again immediately after closing?
This happens due to system services or push notifications. Many applications have autorun mechanisms tied to system events (network reception, time, notification from another application). This can only be completely prohibited through strict restrictions in the battery settings.
Is it possible to close the system “Settings” application?
No, system applications that are part of the Android kernel or shell are protected from being completely stopped by the user. The “Stop” button will be inactive for them, since their work is critical for the functioning of the interface.
How to close a frozen application if the sensor does not work?
If the screen sensor does not respond within one application, try using the navigation buttons (if any) to exit. If it doesn’t help, the only option is to force restart the smartphone by holding down the power button for 10-15 seconds.
Does closing applications affect Internet speed?
It can indirectly influence it. If an application is running in the background, actively downloading data or synchronizing the cloud, it occupies the communication channel. Closing such apps will free up network bandwidth for the current task.
