Modern Xiaomi and Redmi smartphones have powerful hardware, but over time, even flagship models start to slow down and battery power disappears faster than you expect. The main reason for this behavior of the MIUI or HyperOS operating system is often programs that continue to work in the background, consuming CPU and RAM resources. Understanding how to properly manage these processes is the key to extending the life of the device without having to replace it.
Many users mistakenly believe that simply swiping an application card from the running task menu completely stops it from working. In fact, background processes often have system permissions that allow them to restart automatically or continue collecting data even after the interface is closed. In this article, we will examine not only standard methods for stopping programs, but also advanced techniques available through the hidden developer menus.
Competent background settings will not only speed up the interface, but also significantly reduce the heating of the case during downtime. We will look at safe ways to limit activity for social networks, messengers and system services that do not require obtaining superuser rights (Root).
Analysis of resource consumption in battery settings
The first step in optimizing Xiaomi’s smartphone should be to identify the “gluttonous” apps that lurk in the shadows. The operating system keeps detailed statistics on power consumption that often show unexpected results: An application that you rarely use may be at the top of the rank list. → Battery and performance (or simply Battery in newer versions).
In the menu that opens, you'll see a graph of discharge and a list of programs sorted by energy. Pay attention to the high-power items in the background. If you see a navigator that wasn't in use, or a game that was launched an hour ago, that's a signal to action. If you click on a particular application, you'll be taken to a detailed menu where you can force the process to stop or limit its activity.
MIUI offers several levels of constraints, from soft power saving to full shutdown. Background activity can be limited without completely shutting down the application, allowing for push notifications to be saved, but preventing the program from using GPS or the internet in sleep mode. This is the perfect balance for messengers that need to work but don't need to wake the processor all the time.
💡
Use the “Limit Background Activity” feature for applications that don’t require instant messaging, such as online stores or newsfeeds.
It is worth noting that aggressively restricting Google system services or Xiaomi services can lead to unstable smartphone operation. If you are not sure about the purpose of the process, it is better to leave its default settings or pre-examine information about a particular package on the Internet.
Managing permissions and auto-launch applications
One of the main reasons for the software running unchecked in the background is auto-start, and many apps prescribe themselves to auto-boot to open faster when needed, but in reality, they're just hanging in memory waiting for a command, and you can manage this list through the built-in Security app, which is pre-installed on all the devices of the brand.
Open the Security app and find Permissions, and then select AutoRun. This is a complete list of programs that are allowed to start with the system. It is recommended to leave autorunning on only messengers (Telegram, WhatsApp) and alarms. For all other applications, such as marketplaces, maps or social networks, this switch is better translated into the position "Off".
- 🚀 Reducing RAM load: Disabling Autostart Frees RAM Immediately After Turning On the Phone, Making the Interface More Responsive.
- 🔋 Charge savings: Programs won’t start their services immediately after the screen is turned on, saving the battery in the first hours of operation.
- 🛡️ Increased privacy: Fewer apps have the ability to run their trackers and data collectors without you knowing.
In addition to auto-run, check the permissions for “Master on top of other apps” and “Notifications.” Often these permissions allow the program to mine cryptocurrency or display ads even when the screen is off. In the Security → Permissions menu, you can customize in detail what actions are allowed by each program, creating a personalized security policy for your device.

Using Developer Mode to Limit Processes
For advanced users who want to gain maximum control over the system, there is a hidden section called "Developers" that provides tools to severely limit the number of background processes that the operating system can run, the most radical, but also the most effective method of combating "heavy" programs.
To activate this mode, go to Settings → About Phone and quickly click on MIUI Version (or OS Version) seven times. Once the notification “You have become a developer” appears, a new section will appear in the settings menu Additional (or Advanced Settings), and inside it – For Developers. Find the Background Process Limit setting and select “No More than 2 Processes” or “No Background Processes”.
⚠️ Note: Setting a limit of “No background processes” can cause music players to stop when switching tasks, and the navigator will reset the route when blocking the screen.
Also on this menu, it is useful to turn off animations, which will visually speed up the interface. Windows animation, transition animation and animation duration can be translated into "No animation" or "0.5x." This will not turn off the processes, but will make the smartphone work subjectively faster, since the system will not waste resources on rendering unnecessary effects.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Limit of background processes | No more than 2-4. | Strong reduction of RAM load |
| Window animation | 0.5x or Off | Accelerating interface response |
| Inactive applications | Stop it. | Forced shutdown of long-defunct programs |
| MIUI background restriction | Included. | Standard system optimization |
What to do if the item “For developers” is missing?
Forced stopping and cleaning of memory
There is a difference between closing an application with a swipe and stopping it completely through settings. When you swipe a card, the system often leaves processes alive for fast recovery. To completely kill the process, you need to go to Settings → Applications → All applications, select the desired program and click on the Stop button.
This procedure is especially useful for applications that have “hanged” or started to malfunction, consuming CPU time. Once you press the Stop button, the program is completely removed from RAM and can not start again until you open the shortcut yourself. This is a great way to refresh the work of a heavy application before important use.
But remember, manual memory cleaning isn't always helpful. Android is designed to keep frequently used apps in memory for quick access. If you keep cleaning everything, the processor will spend more energy restarting programs than holding them in the background.
- 🧹 Problem Solving: Use a forced stop if the app doesn't respond or heats up the phone.
- ⚡ Quick Start: Don’t stop the frequently used messengers so you don’t lose the speed of their opening.
- 🔄 Status reset: Stopping helps to reset accumulated errors in the program’s cache without deleting it.
For quick memory cleaning, you can use the built-in feature in the menu of running applications (the “Garbage bin” button or cross). But for deep cleaning, you can use the Security → Cleanup application, which analyzes processes in more detail and suggests removing residual files.
Optimization through hidden MIUI settings
The MIUI shell and the new HyperOS have their own memory management algorithms that are sometimes too aggressive and sometimes not enough. In the Settings → Battery section (or through the Security app), you can find optimization settings for each application. By clicking on the gear in the corner or selecting a specific application, you can set the mode: “No limits”, “Saving charge” or “Strict limitation”.
No Limits mode should only be enabled for programs that need to be alerted instantly (such as work chats or alarms). For everyone else, especially social media and gaming, it’s better to choose a standard mode or power saving mode, which will prevent the application from running its services when the screen is off.
Also in newer versions of firmware, the Memory Extension feature has been introduced, which uses part of the internal memory as virtual RAM. While this sounds useful, for background applications, this can play a cruel joke: the system will keep more programs in the background, but they will work slower due to the lower speed of flash memory compared to RAM. If your goal is maximum performance, try turning off the memory expansion in the settings Additional → Expansion of memory.
⚠️ Warning: Disabling background activity for Google Play Services or Mi Cloud Service system applications can lead to contact disappearance, photo synchronization stops and geolocation failures.
Remember to update apps regularly through Google Play or GetApps. Developers often release patches that optimize background resource consumption. The old version of the app may contain a bug that causes a "memory leak" that is fixed in the new version.
Radical measures: freeze and ADB
If standard methods don’t work and a particular application continues to live its life, you can resort to “freeze” without having to get a Root right. There are freezer applications (such as Hail or Ice Box) that use the ADB (Android Debug Bridge) rights to deactivate system components without removing them.
You'll need a computer and a cable to use this method. You'll need to enable USB debugging on your phone in the Developer Menu. Then, by connecting to your PC, you can send a command to disable the package via the command line. For example, pm disable-user --user 0 com.example.app will completely disable the specified application until you turn it back on.
adb shell pm disable-user --user 0 name.packet.applicationsThis method turns an application into a system that is not visible on the menu and cannot be launched. It is the ideal way to deal with undeleteable system debris (bloatware), which is pre-installed on your smartphone and constantly hangs in the background. However, use this method with extreme caution: disabling critical system components can lead to a “brick” of the device or bootloom.
💡
Using ADB to freeze is the most effective way to completely remove a system application from the background processes without removing it, but requires accuracy in command input.
In conclusion, the comprehensive approach to managing background applications on Xiaomi Redmi includes autostart configuration, competent use of energy saving modes and periodic revision of installed programs. You should not chase for absolute cleanliness of processes if it interferes with comfortable use of your smartphone. Find a balance between autonomy and functionality that suits your use case.
