Brand smartphones Xiaomi are famous for their price-performance ratio, but over time, even powerful devices begin to freeze. Most often, the reason lies not in a lack of processor power, but in overflow RAM (RAM). The operating system manages resources aggressively, but background processes can accumulate, causing the interface to slow down. MIUI or HyperOS aggressively manages resources, but background processes can accumulate, causing the interface to slow down.
Users often notice that applications are unloaded from memory immediately after switching to another window. This is a sure sign that there is critically little free space. Unlike the internal memory, where photos and files are stored, RAM only works during active use of the gadget and requires constant RAM critically low. Unlike the internal memory, where photos and files are stored, RAM only works during active use of the gadget and requires constant optimization. Let's look at proven cleaning methods.
It is worth understanding that completely “empty” RAM is a myth. The Android system is designed to use free RAM to cache frequently used apps. Our goal is not to reset the indicators, but to remove “garbage” processes that really slow down the operation of smartphone.
Using the built-in Security application
The easiest and safest way to start cleaning is to use a standard tool from the manufacturer. Each device Xiaomi has a pre-installed application Securitythat has access to system processes at a deep level.
Launch the app and find a large button with the inscription Cleaning or a broom icon. Clicking on it will start a system scan. The algorithm will analyze the application cache, residual files and the fullness of RAM.
After the scan is completed, the system will offer to free up space. Pay attention to the section Memory: the percentage of RAM load is displayed here. Click the cleanup button to forcefully end background processes. This action will temporarily free up resources, but will not radically solve the problem if some applications are constantly restarted.
⚠️ Attention: Do not use third-party “accelerators” from the Play Market with aggressive advertising. The built-in tool Xiaomi works more correctly, since it has system process rights, unlike third-party software, which often consumes a lot of resources.
For more in-depth work, go to the application settings Security. There you can configure automatic cleaning when a certain loading threshold is reached. RAM. This is useful if you do not want to manually monitor the system status every hour.
Set automatic cleaning in the Security application at 80% of RAM load - this will prevent critical freezes during games.
Manual control of applications and autostart
Many apps register themselves in startup, launching immediately after turning on the screen. This is the main enemy of free RAM. The shell has a special section to control this behavior, which is often ignored by users. Go to the menu, then select the item. Find the section MIUI There is a special section to control this behavior, which is often ignored by users.
Go to menu Settings, then select Applications. Find a section Autorun. Here you will see a list of all apps that start with the system. Disable everything that is not vital: you can leave messengers, but it is better to prohibit stores, news and games.
It is also worth checking application permissions. Some apps require constant work in the background for non-obvious functions. Go to Settings → Applications → All applications. Select a suspicious app, click Battery saving and set a limit "Limit background activity". This will prevent the application from eating up memory when you are not using it.
- 🚀 Disable autorun for social networks if you do not need instant notifications.
- 🛑 Disable background operation for heavy games and launchers.
- ⚙️ Check synchronization services: often Google Photos or Yandex.Disk loads memory when loading.
If after these steps the phone still slows down, perhaps the problem is in a specific “heavy” application. Try uninstalling it and installing a lightweight version (Lite), which consumes significantly less RAM.

Hidden developer settings for cleaning RAM
For advanced users in Android there is a menu hidden by default. It allows you to control system behavior at a low level, including forcibly limiting the number of background processes.
To activate this mode, go to Settings → About phone. Find the item MIUI version (or OS version) and quickly click on it 7-10 times in a row. A notification will appear indicating that you have become a developer.
Now return to the main settings menu and open section Advanced → For developers. Find the item Background process limit. By default there is “Standard limit”. You can change it to "No more than 2 processes" or "No more than 4 processes."
⚠️ Attention: Setting a hard background process limit may cause the music to stop when minimized player, and the navigator will reset the route when switching screens. Use this setting with caution.
There is also an option Do not save actionsin this menu. If you enable it, the system will destroy application activity as soon as you leave its screen. This will free up as much as possible RAM, but will make multitasking impossible - each application will be opened anew from scratch.
Why do we need the “Android System” process in memory?
The “Android System” process takes up a significant part of RAM, since it is responsible for basic interface functions, communication and resource management. It cannot be terminated or removed; it is the core of the system. Attempts to “clean” it through third-party apps are useless and may cause a reboot.
Another useful setting for speeding up is the animation scale. In the same developer menu, find three items: Window animation scale, Transition animation scale and Animator duration scale. Set the value 0.5x or Off. This will not clear memory physically, but will visually speed up the responsiveness of the interface by Xiaomi.
Analyzing memory consumption and identifying the culprits
Sometimes the cause of a memory leak is difficult to find by eye. Built-in tools may not show detailed statistics for each process in real time. To do this, it is better to use specialized utilities or the built-in monitor.
In the menu For developers there is an item Running services (or Running services). It displays a list of all active processes and the amount of space they occupy RAM. If you see an application that you have not launched, but it consumes 500 MB of memory, this is a reason to delete it or disable it from running in the background.
| Process type | Normal consumption | Action |
|---|---|---|
| System services | 1.5 - 3 GB | Do not touch |
| Messengers (Telegram, WhatsApp) | 100 - 300 MB | Leave if notifications are needed |
| Social networks (VK, Instagram) | 200 - 500 MB | Limit background or use Lite |
| Games (in the background) | 0 MB (must be closed) | Force stop |
Pay attention to applications marked System UI. If they are consuming an abnormally large amount of resources, the system may have crashed. In this case, a simple one will help reboot device, which will reset all temporary accumulations in RAM.
Clearing the cache and temporary files
Although the cache is stored primarily in internal memory, its excess indirectly affects operation RAMas the system has to index and maintain this data. Regularly clearing the cache is an important part of prevention.
Go to Settings → Memory. The system will show how much space is occupied by the cache. Click on this line and confirm the cleaning. This is safe: the cache is temporary data that applications will download again if necessary.
For individual “heavy” applications, such as TikTok, YouTube or browsers, it is better to clear the cache individually. Go to Settings → Applications → Select application → Memory → Clear cache. Do not click “Clear all”, otherwise you will lose logins and login settings.
Browsers often become the main ones resource hogs due to open tabs. Each open tab in Chrome or MIUI Browser occupies its own piece RAM. Close unused tabs or use the “Close All” function in the browser menu.
Regularly clearing the cache of browsers and social networks not only frees up disk space, but also reduces the load on RAM when running these applications.
Radical measures: reset and update
If software the methods do not help and the phone continues to slow down even after cleaning; perhaps errors or conflicting files have accumulated in the system. In this case, deeper intervention is required.
The first step should be a firmware update. Go to Settings → About the phone and check for updates. Engineers Xiaomi often release patches that optimize memory in new versions HyperOS or MIUI.
⚠️ Attention: Before updating the firmware, be sure to charge the phone to at least 60% and connect it to Wi-Fi. Interrupting the update process may damage the device.
The last resort is a full reset to factory settings (Hard Reset). This will delete all data, but return the phone to its “out of the box” state, completely clearing RAM of software debris. Before doing this, be sure to back up your contacts and photos to the cloud.
To perform a reset, go to Settings → Advanced settings → Restore and reset → Reset settings. The device will reboot and begin the cleaning process. After setup, reinstall only the necessary applications so as not to clog the system right away.
Does “Mode” help? developer" is real?
Yes, but with reservations. Limiting background processes actually frees up RAM, but at the cost of convenience. This is an excellent solution for older models with 2-3 GB of memory, but on modern flagships with 8-12 GB of RAM this can only complicate life, since the system itself manages resources perfectly.
Frequently asked questions (FAQ)
Is it true that widgets on the desktop eat up RAM?
Yes, it's true. Each active widget (weather, news, clock) is a separate process that is constantly updated and takes up space in RAM. If memory is low, remove unnecessary widgets from the main screen.
Do you need to close applications through the "Tasks" menu?
In modern versions of Android and MIUI there is no urgent need for this. The system itself unloads unused applications. Constantly closing tabs is even harmful, since launching the application again wastes more energy and processor resources.
Why does the memory fill up again after 5 minutes after cleaning?
This is normal Android behavior. The system preloads frequently used applications into RAMso that they open instantly. If the phone does not slow down, then full memory is good, not bad.
Can a virus cause a memory leak on Xiaomi?
Yes, malware can work in hidden mode and consume resources. If you notice abnormal heating and rapid battery drain along with a lack of memory, check the device with an antivirus from the application. Security.
Does full internal memory affect the operation of RAM?
Indirectly. If the internal memory is full to capacity, the system has no place to create swap files, which can lead to unstable operation and application crashes, even if RAM formally free.
