Modern Xiaomi smartphones with a shell MIUI or HyperOS are famous for their aggressive memory management, but users often face a situation where certain programs continue to consume resources even after closing. background activity can be caused by a variety of reasons, from the need to receive notifications to hidden data synchronization, which ultimately leads to accelerated battery discharge and heating of the device case.
Device owners need to understand the difference between shutting down the program completely and limiting its background, as Android’s system mechanisms tend to keep as many running processes as possible in memory for quick switching. In this article, we’ll detail how to forcefully stop unnecessary processes, set up auto-start, and use built-in optimization tools to make your smartphone work as efficiently as possible.
Controlling backgrounds is not only a way to extend battery life, but also a security measure to limit third-party software’s access to geolocation and microphone when you’re not using them, and by setting these parameters correctly, you can turn a standard device into a tool that works exactly the way its owner wants it to, without unnecessary “junk” traffic and CPU load.
Why applications work in the background and how it affects the system
The main reason for the constant activity of programs lies in the architecture of the Android operating system, which was originally designed for multitasking. App developers strive to maintain constant communication with the server for instant notification delivery, updating the news feed or tracking location, which requires a constant connection to the network and periodic wake up of the processor.
On Xiaomi devices, the situation is aggravated by the presence of many pre-installed services and third-party software, which often prescribes itself for autoboot. Background activity consumes RAM, causing the system to access the paging file more often, which can lead to micro-freezes of the interface when opening heavy games or cameras.
In addition, constant work in the background creates parasitic traffic that can be critical when using mobile Internet with a limited tariff. the user may not even suspect that a simple flashlight application or calculator periodically sends data packets to a remote server for analytics or displaying targeted advertising.
Not all background processes are harmful: messengers, email clients, and navigators must be constantly working to perform their functions, but if you notice that a particular application consumes a disproportionate amount of resources, you should manually limit its work through system settings.
Basic application closure through Task Manager
The easiest and most obvious way to stop the program is to use the built-in Task Manager, which is done by swiping from the bottom up on Xiaomi smartphones (or clicking the menu button, depending on the type of navigation), and then opening a list of cards of newly opened applications.
To completely close all programs at once, just press the cross button at the bottom of the screen or in the corner of the task list, but this method only frees up RAM, but does not prevent the application from automatically starting again through system services or on a schedule.
- 📱 Press the menu button or swipe to open the task list.
- ❌ Click on the cross to clear all cards at once.
- 🔄 Swipe up a specific card to force the closure of a separate application.
It is important to understand that the standard closing through the multitasking menu is temporary, and the MIUI system can start the process again if it considers it necessary for the stable operation of other components, so more advanced customization tools are required for deep cleaning.
💡
Use the Memory Cleanup widget on your desktop for quick access to the background process closure function without having to flip through the menu.
If you want to not just close the program, but completely forbid it to run until you open its icon yourself, you need to move to deeper application management settings, which will be discussed in the next sections.
Limiting background activity through battery settings
The most effective standard method of combating energy eaters is to adjust the energy saving parameters for each specific application. In the MIUI shell, there is a separate menu that allows you to monitor the behavior of programs in the background in detail, without removing them or turning them off completely.
To access these settings, go to Settings → Battery and Performance → Energy Consumption. Here is a list of all installed programs, sorted by energy expended, allowing you to quickly identify the “culprits” of the quick discharge.
Settings → Battery → Energy Consumption → Application Selection → SettingsIn the menu that opens, you'll find "Background Activity" or "Energy Saving" where you can choose between modes of operation, the most stringent mode completely prohibits the application from running when it's rolled up, which guarantees no charge consumption, but can cause a delay in receiving notifications.
- 🔋 "No restrictions" - the application is working at full strength, constantly updated in the background.
- ⚖️ "Smart Constraints: The system decides when to restrict work based on usage patterns.
- 🚫 "Limit background activity" - a strict ban on any program actions in a folded state.
☑️ Checking battery settings
The use of rigid restrictions is especially important for games, video players and utilities that do not require a permanent connection to the Internet. Once you apply the settings, the changes take effect immediately, and the application will no longer be able to run its services without your knowledge.
Managing Auto-Run and Application Permissions
One of the main reasons apps keep running in the background on Xiaomi is the auto-start feature, which many programs prescribe themselves to this list when they first install to ensure notifications are delivered, but often this leads to an excessive load on the system immediately after the smartphone is turned on.
Autorun control is in the Security app, which is pre-installed on all the brand's devices. Going to Permissions and selecting the AutoStart tab, you'll see a complete list of programs that start with the system. Disabling unnecessary positions here greatly speeds up the phone's boot.
⚠️ Warning: Do not disable auto-start for system components MIUI, Google Play and messaging services, if you want to receive notifications on time, can cause the interface to be unstable or lose important messages.
Beyond auto-run, it’s worth checking application permissions, especially access to location and background data. In the Settings menu → Apps → All Apps → Program Selection → Permissions you can deny access to geo-position in the background, leaving it only when in use.
Also in this section, it is useful to disable display over other windows for suspicious programs, as this is often used for intrusive advertising that can trigger processes even without active user interaction with the screen.
Hidden Android Services
Regularly checking the boot list and permissions helps maintain the operating system’s “hygiene” by preventing the accumulation of software debris that slows down the device and wastes battery life.
Comparison of process stop methods
For the convenience of users, we have prepared a comparison table that will help you choose the best method of managing background processes depending on your goals.
| Method | Impact on the battery | Impact on notifications | Difficulty setting up |
|---|---|---|---|
| Closing through the menu | Minimum | Not affected (coming later) | Low. |
| Limitation in battery settings | High. | Notifications may not be coming | Medium |
| Shutting down autostart | Average (only at start) | Does not affect the work in the background | Low. |
| Completely shutting down the app | Maximum. | Total absence | Tall. |
As you can see from the table, the most effective method for saving charge is to limit the battery settings, but it requires careful approach to configuring each application individually. The combination of methods gives the best result: disabling auto-start for rare programs and tight battery restriction for heavy applications.
Users who want to achieve maximum autonomy are advised to audit all installed programs and apply the appropriate method of restriction for each category of software, dividing them into "necessary" and "background".
💡
The combination of disabling autostart and setting the "Limit background activity" mode gives the maximum increase in battery life without loss of functionality.
Using Developer Mode to Forced Stop
For advanced users who don’t have enough regular resources, there is the ability to manage processes through the Developer Menu, which provides deeper control over the system, allowing you to stop services and limit the number of background processes globally.
To activate this mode, you need to go to Settings → About phone and quickly click on the version of MIUI seven times. After the message “You became a developer” appears in the settings menu, a new item “Additional” or “Extended settings” will appear, where the desired menu is located.
In the "Developers" section, we're interested in the "Limit of Background Processes" section, where you can set a limit on the number of applications running simultaneously, such as "No more than 2 processes." All other programs will be forced to stop by the system.
⚠️ Attention: Setting too strict a limit of background processes can lead to system failures, reboots or incorrect display of the interface. Use this function with caution and only understanding the consequences.
Also available on this menu is the "Do Not Stay Activity" feature, which destroys the application as soon as the user leaves the screen, a radical method that is useful for testing, but extremely inconvenient for everyday use, since it resets the state of all programs.
- 🛠 Activate the developer mode with seven times pressing the OS version.
- 📉 Find the item "Limit of background processes" in the developer menu.
- 🔒 Select the value of "No background processes" or limit their number.
Using the developer tools allows you to temporarily “freeze” excess activity, but for permanent use it is better to return to standard battery settings, which work more predictably and safely for data integrity.
