How to Disable Apps in the Background: A Complete Guide to Optimization

Xiaomi’s current smartphones, which are running MIUI shells or the new HyperOS, have powerful features that don’t always work for the user. Often, device owners notice that the battery runs out faster than expected, and the phone heats up even at rest, and the reason for this is dozens of processes that continue to work even when you fold the program or lock the screen.

Android is designed to keep apps ready to launch instantly, but in the realities of Chinese smartphones, it leads to over-consumption of resources. Background activity may be good for messengers, but not necessary for games or heavy editors that you don't use right now. Understanding how to manage these processes is key to extending autonomy.

In this article, we will examine not only standard methods of stopping programs, but also the deeper system settings available in the developer menu and special features. You will learn to distinguish between systemically important processes and those that can be safely limited without compromising the stability of the gadget.

Why apps continue to work after closing

Many users mistakenly rely on swipe up the menu of recent apps, considering it an action of complete closure. In fact, in the architecture of Android, it is only a removal of the shortcut from the list of running tasks, but the process itself often remains hanging in RAM. The system does this deliberately so that when you re-start the application opens instantly, rather than undergoing a long initialization procedure.

But there is a category of software that uses background services to collect data, update content, or display ads. In the Xiaomi ecosystem, the situation is exacerbated by the presence of its own services and aggressive optimization, which sometimes works the opposite way — not closing the redundant, but only redistributing resources. Some applications have permissions to start by boot, which forces them to activate immediately after the phone is turned on.

Social media and instant messengers are a big focus, and they often ignore standard restrictions, using push notifications as a way to keep the connection active all the time. If you don't manually set exceptions, the phone will constantly waste energy on maintaining communication with the servers, even if you don't use these services for hours.

⚠️ Warning: Completely stop system applications such as “Security”, “Google Play Services” or "MIUI Home may cause unstable interface operation or loss of notifications from important services.

The difference between a standard shutdown and a forced shutdown is enormous, and the first one only clears the visual cache of tasks, whereas the second one, a forced shutdown, actually kills the process in memory until you start the application manually again or the system decides to restart it on schedule.

Basic methods of stopping through the application menu

The easiest and safest way to stop a particular program is to use the built-in application management menu, which requires no root rights and is available on any Xiaomi device out of the box, and is ideal for a one-time solution to a problem with an overheated application that consumes charge.

To do this, you need to go to the basic settings of the device. The path usually looks like: Settings → Applications → All applications. Here is a complete list of installed software, including system components and user downloads. Find the desired application in the list that you want to limit.

Once you log in to the app card, you will see a Stop (or Close) button, which will force all associated processes to be terminated by clicking on, but remember that if the application has auto-start rights, it may be activated again after a while or after the device has restarted.

And there's also the important AutoRun tab, which is the reason why many programs come back to memory right after they close, and disabling the slider in the AutoRun section prevents the application from starting with the operating system, which significantly reduces the CPU load in the first minutes after the phone is turned on.

Use of MIUI energy saving mode

The MIUI and HyperOS shells have a powerful background monitoring tool called Battery and Performance (or simply Battery) built in, which allows you to set individual rules of behavior for each application installed, determining how aggressively the system will limit their performance in the background.

Inside the battery menu, go to Settings → Battery → Application Charge Savings (the path may vary slightly depending on the firmware version). Here you will see a list of all programs with current constraint status. Most applications have a default value of "No Limits" that allows them to run continuously.

For each application, you can choose one of three modes of operation that radically change its behavior:

• 🔋 Without limitation: the application can run freely in the background using the network and GPS. Recommended only for messengers and alarm clocks.
• 🛑 Limit background activity: the system will limit background processes if the application is not used for more than 10 minutes.
• 🚫 Limit activity in the background: the most stringent mode, which almost completely prohibits background work, leaving only basic functions.

When choosing the Background Limit Activity mode, you should be prepared for notifications from this app to come late or not at all until you open it again.This is the perfect setting for games, video editors and stores that don’t require a constant connection.

💡

For instant messengers (WhatsApp, Telegram) always choose the "No Limits" mode, otherwise you will stop receiving messages in real time.

It is important to note that after an operating system update, your energy saving settings may reset to default values. Check this section periodically to ensure that your optimizations continue to work efficiently.

Setting restrictions through the developer menu

For advanced users who want to gain maximum control over the system, there is a hidden developer menu available, which is set up to influence the global behavior of the Android operating system with respect to background processes, and access to this menu must be activated separately.

To open access, go to Settings. → On the phone and press. 7-10 once in a row in the field "Version" MIUI" (or "Version". OS"), until you get a notification that you've become a developer, and then a new option will appear in the main settings menu, "More" → "For developers".

Inside the developer menu, we're interested in the "Applications" section, and you can find the "Background Process Limit" option, which is set to the "Standard Limit" setting by default, which allows the system to decide how many processes to store, and changing this setting allows you to severely limit the number of simultaneous background applications.

The available limit options include:

• 📉 No background processes: A radical mode in which any curled process is destroyed immediately.
• 🔢 Not anymore. 1-4 processes: allows you to keep in memory only a specified number of applications.

⚠️ Attention: Setting a rigid limit of background processes can lead to the fact that the music in the player will stop when switching to other programs, and the navigator will stop plotting the route in the rolled-up form.

Also on the developer menu, you should pay attention to the "Do Not Activity" option, which is that if you turn on this switch, the system will destroy the activity of the application as soon as the user switches to another task, which is an extremely aggressive setup, useful only for testing or on very old devices with minimal RAM.

Table of comparison of restriction methods

To make it easier for you to choose the right method for controlling background activity, we have prepared a summary table that demonstrates the effectiveness of different approaches and their impact on the performance of the Xiaomi smartphone.

As the table shows, the most balanced approach is to combine methods: disabling autoruns for unnecessary programs and setting “Limit background activity” modes for heavy applications.

The effectiveness of each method also depends on the amount of RAM your device has, and on smartphones with 6GB of RAM or more, the system itself does a pretty good job of managing memory, and tight restrictions can even hurt the speed of the interface.

Advanced settings of special features

There is another powerful tool in MIUI’s arsenal that not everyone knows about: memory expansion and background task management through special features. Some system optimizers preinstalled in the shell can force applications to close if you configure the appropriate scripts.

Also, check Settings → Advanced Settings → Availability. This may be a service that monitors the use of other applications. While you can’t directly disable applications here, disabling unnecessary accessibility services (such as remote management or suspicious applications) reduces the overall workload of the processor.

Special attention should be paid to the Memory Extension feature, which uses part of the built-in drive as virtual RAM. Paradoxically, on some Xiaomi models, the inclusion of this feature leads to the system actively holding applications in the background using slow flash memory, which may even increase energy consumption.

• 🚀 Disable Memory Expansion: If your goal is maximum autonomy, try turning off virtual memory in the About Phone settings. This will make the system more aggressive in cleaning up real-world processes. RAM.
• 🧹 Cache Cleanup: Regularly cleaning the cache through the built-in cleaner also helps reduce background load by removing temporary files that can cause service disruptions.

⚠️ Note: Do not install third-party “Task Killers” from Google Play. In modern versions of Android, they work incorrectly and often consume more resources than the applications themselves that try to close.

The use of native tools is always preferable to third-party software, and MIUI algorithms are already smart enough to manage resources if they are not interfered with by conflicting programs.

💡

The best optimization is to manually adjust auto-start and battery limitations for each specific application, rather than using global cleaners.
