How to Clean RAM on Xiaomi: The Complete 2026 Guide

Why Xiaomi is “slowing down” and how it relates to RAM

Have you noticed that your Xiaomi, Redmi or Poco are slowing down? Apps are slow to open, animations are “suppressed”, and sometimes the phone completely forcibly closes the background processes? 90% of cases are to blame for overloaded RAM (RAM). Despite the fact that modern smartphones are equipped with 8-12 GB of RAM, MIUI aggressively caches data and often does not optimize the allocation of resources between applications.

Controlling RAM usage on Xiaomi is more difficult than on Android’s “naked” one. The manufacturer hides many settings behind a layer of proprietary shell, and standard cleaning methods (such as through Task Manager) often have a temporary effect. In this article, 7 proven ways to free up RAM, including hidden MIUI features, developer commands, and root-free automatic optimization.

Before we start cleaning, it's important to understand that RAM is not designed to be permanently "released"; its job is to store data from active processes. If the memory is empty, it's a sign that the system is killing background tasks too aggressively, and our goal is not to achieve "0% usage," but to balance performance and power consumption.

How to check the loading of RAM on Xiaomi

Before cleaning up RAM, you need to assess the current situation, and MIUI has built-in monitoring tools, but they're hidden from the average user.

1. Open the Settings. → The phone.
2. Tap 5-7 times on the MIUI version until the notification “You became a developer” appears.
3. Go back to the main settings menu and find a new Developer section (usually at the bottom of the list).
4. Scroll down to the Debugging block and turn on the Memory Statistics option.

Now, the notification bar will display the RAM usage indicator.

• 📊 Go to Settings. → Annexes → Application management → Memory statistics. This is the process that consumes the most RAM.
• 🔍 Use third-party utilities like DevCheck or CPU Monitor (available on Google Play) shows detailed analysis of the cores of the processor and dedicated memory.
• 🛠️ For advanced users: connect your phone to your PC and use the adb shell dumpsys meminfo command in the terminal (requires enabled). USB-debugging).

⚠️ Warning: If you see a com.miui.guardprovider process that consumes more than 500 MB in memory statistics, that's OK. MIUI and must not be removed.

Method 1: Manual cleaning through Task Manager

The simplest, but also the least effective method. MIUI offers a built-in tool to close background applications, however, it does not clear the system cache or optimize memory allocation.

Instructions:

1. Click on the recent apps button (usually swipe up with a 0.5 sec delay).
2. At the bottom of the screen will appear button Clean all (on some models – the icon of the basket).
3. For selective cleaning, swipe left/right on the application card and swipe it up.

Cons of the method:

• 🔄 Applications will restart the next time they open, which consumes more. RAM, purification.
• 🚫 Does not delete system processes (e.g. miui.daemon or android.process.media).
• ⏳ The effect lasts 10–30 minutes, and then the memory is filled again.

💡

If the “Clean All” button is missing, turn it on in the settings: Settings → Screen → Recent Apps → Show the Cleanup button.

Method 2: Optimization with Security App

The proprietary Security app (or Global Firmware Security) contains tools for deep cleaning RAM. Unlike the Task Manager, it removes the cache of system processes and temporary files that occupy memory.

Step-by-step:

1. Open the Security app (shield icon).
2. Go to the Optimization (or Boost) tab.
3. Click Clear Memory (could be called Deep Clean).
4. Wait for the analysis and confirm the cleanup.

Additional settings:

• 🔧 Enable Auto Cleanup in the app settings to RAM Optimized when blocking the screen.
• 📴 Turn off optimization recommendations if you don’t want to receive notifications.
• 🛡️ In the AutoRun Management section, disable the autoload of unnecessary apps (this will reduce background consumption). RAM).

⚠️ Attention: Don't clean. RAM Security more than 3-4 times a day, which can cause premature wear of flash memory due to frequent recording operations.

Method 3: Configure the developer parameters for RAM

MIUI hides a number of parameters that affect memory management, and you can activate them through the developer menu, and these settings don't delete data, they optimize how it's processed.

Key parameters:

• 🔄 No Save Actions – limits the number of background processes recommended: 2–3 processes (default: 4).
• 🚀 Process Limitation: Maximizes the number of applications running simultaneously, optimal: Standard Limit or Process Max. 3.
• 🗑️ Do not remain active - forcibly closes applications when you exit. It is not recommended to turn on constantly - this will accelerate battery discharge.
• 🔍 Turn on 4x MSAA — Improves graphics, but consumes more RAM. Turn it off if you play light games.

How to change the settings:

1. Activate Developer Mode (see How to Check RAM Download).
2. Go to Settings. → For developers.
3. Find the Application block and change the settings as indicated above.
4. Restart your phone to apply the changes.

Method 4: Cleaning RAM through ADB (for advanced)

If standard methods don't work, you can use Android Debug Bridge (ADB), a low-level system management tool that requires a PC and basic command line knowledge.

Step-by-step:

1. Download Platform Tools from Google’s official website and unpack the archive.
2. Turn on the phone Debugging over USB (Settings → For developers).
3. Connect your phone to your PC and open the terminal (or cmd in Windows) in the folder with Platform Tools.
4. Enter the command to check the connection: Adb devices should appear the name of your device.
5. Perform the cleanup. RAM: adb shell "echo 3 > /proc/sys/vm/drop_caches" This command resets the kernel cache without closing the applications.

Additional useful commands:

• 📊 Read more about Adb shell dumpsys meminfo
• 🔄 Forced to close an unnecessary process (replace com.example.app in the name of the package): adb shell am force-stop com.example.app
• 🛠️ Set a limit on background processes (for example, on the 2): adb shell settings put global bg_process_limit 2

⚠️ Attention: Echo Team 3 > /proc/sys/vm/drop_caches It doesn't delete user data, but it can cause a short-term interface freeze.

Method 5: Disconnecting unnecessary system processes

MIUI contains many background services that can't be removed without root, but can be disabled, some of which consume up to 300-500MB of RAM for no apparent benefit.

List of safe processes to disable (via Settings → Applications → All applications):

• 🎵 MusicFX – uniform sound setting (unless you use an equalizer).
• 📡 Mi Roaming – Roaming service (useless if you are not traveling).
• 📦 Download Provider – Download Manager (you can disable if you use third-party downloaders).
• 📱 MiuiDaemon - System Demon MIUI (Shutdown can lead to bugs, but saves up to 200MB).
• 🔊 SoundRecorder – Standard Dictaphone (if you don’t use it).

How to turn it off:

1. Open Settings → Applications → All applications.
2. Find the right app by name (use search).
3. Click Disable (Do not "Delete"!).
4. Confirm the action. The app will stop working, but its data will be saved.

Processes that cannot be turned off:

• 🚫 com.android.phone – phone calls.
• 🚫 com.miui.home - launcher MIUI.
• 🚫 android.process.media – managing media files.

Method 6: Use of third-party optimizers (with caution!)

There are hundreds of apps on Google Play that promise to speed up your Xiaomi by cleaning up RAM, but most of them are dummy or malware. We tested 15 popular utilities and selected 3 relatively safe options:

How to use Greenify (the best choice for Xiaomi):

1. Download and install the app from Google Play.
2. Provide access to special features (Settings → Special Opportunities → Greenify).
3. Add apps you want to “sleep” (like Facebook, Instagram).
4. Enable the option of automatic hibernation.

⚠️ Note: Do not use "boosters" RAM» Like a clean master or something. DU Speed Booster. These apps: 🛑 Starting background processes that consume RAM. 📢 False notifications about the “critical state” of memory. 🔒 Can collect personal data (based on SophosLabs 2023 research).

Method 7: Reset to factory settings (last resort)

If all the previous methods didn't work, and the phone is still slowing down because of a lack of RAM, there's a complete reset, which will delete all the data, but return the system to its original state, where RAM is optimally distributed.

How to do the reset correctly:

1. Create a backup through Settings → Additional → Backup and Reset.
2. Move your important files to your PC or cloud (Google Drive, Mi Cloud).
3. Go to Settings → About the phone → Reset settings.
4. Choose to erase all data and confirm the action.
5. After the reboot, set the phone up as new (don’t restore data from the backup right away – check RAM work).

What to do after the discharge:

• 📱 Don’t install all apps at once – add them one at a time while watching your consumption. RAM.
• 🔄 Turn off auto-update apps on Google Play.
• 🛡️ Do not restore data from backup MIUI — It may contain “junk” files.

💡

Factory resetting is the only way to return the original RAM distribution if the system has been littered with years of use, but it is an extreme measure: try all other methods before resorting to it.
