How to Free RAM on Xiaomi: A Complete Guide with Proven Methods

Your Xiaomi, Redmi or POCO are slowing down, apps are spontaneously shutting down, and there's a memory shortage warning in the Task Manager? The problem is overloaded RAM. Even flagships with 12GB of RAM accumulate background processes, cache and junk tasks that eat up resources. In this article, 10 proven ways to free RAM without root rights, resetting to factory settings or buying a new phone.

We'll take it down like standard tools. MIUI, And there are hidden features that are not mentioned in the official manuals, and we'll focus on automated solutions (to avoid manually cleaning your memory every day) and dangerous myths that only worsen performance. MIUI 14/15 HyperOS (2026 year).

1. Diagnostics: how to check the RAM load on Xiaomi

Before you clean up your memory, you need to understand what it's doing. MIUI has a built-in resource monitor, but it's hidden in the back of the menu.

1. Go to Settings. → The phone.
2. Tap 5 times on the line version of MIUI (the message will appear "You became a developer").
3. Return to the main settings menu and open Additional → For developers → Memory Monitor.

Here you will see a graph of real-time RAM usage, a list of the most voracious applications and system processes.

• 🔴 Background processes – applications that do not close even after swiping in Task Manager.
• 🟡 Dalvik cache – temporary files of the Android virtual machine that can inflate to hundreds of megabytes.
• 🟢 System services such as com.miui.analytics or com.xiaomi.midrop, which often work unnecessarily.

💡

If you see a high-load kswapd0 process in the memory monitor, this is a sign of a lack of RAM. The system actively uses the paging file on the internal drive, which slows down the phone.

For more detailed analysis, use third-party utilities like DevCheck or Simple System Monitor (available on Google Play), which will show not only the current download, but also the history of RAM use in recent hours.

2. Basic cleaning: Task Manager and cache

The most obvious, but often underrated, way to do this is to use the built-in Task Manager correctly, and many users just swipe apps up, but it doesn't shut them down completely, it just takes them off the screen. Here's how to clean up RAM for real:

1. Open Recent Apps (the button with a square or swipe from the bottom up with a pause).
2. Slip the basket icon (or “Close All”) at the bottom of the screen.
3. For selective cleaning: pinch the card of the unwanted application and select Close.

However, even this doesn't remove the app cache, which can take up to 1-2GB of RAM.

• 📱 Go to Settings. → Annexes → Application management.
• 🔍 Select the “heaviest” app (e.g. Facebook, Instagram or Play Store).
• 🧹 Click Clear Cache (not to be confused with Clear Data – this will delete accounts!).

Important: Clearing the cache of applications like Google Play Services or MIUI System can cause temporary service disruptions (e.g., push notifications will stop coming) and only do this if you see a critical memory deficit.

3. Optimization of application autoloading

Many apps run automatically when you turn on your phone or connect to the Internet, even if you don't use them. This is one of the main reasons for constant RAM overload. MIUI has a hidden setting to control the boot:

1. Open Settings → Applications → Application Management.
2. Slip on the three dots in the upper right corner and select AutoRun.
3. Turn off autoboot for all unnecessary applications (especially for games, social networks and instant messengers).

For more in-depth optimization:

• 🛑 Go to Settings. → Battery and productivity → Battery management.
• 🔋 Select Charge Saving Mode – It limits the background activity of applications.
• ⚡ Enable the option to limit background activity for the most voracious programs.

Disable auto-start for games and social networks|Limit background activity of messengers|Enable battery saving mode|Check autoboot after installing new apps-->

Exceptions: Do not disable autoboot for system applications like Google Play Services, MIUI Security or Telephony Provider – this can disrupt your phone.

4.Using the Deep Cleanup function in MIUI

MIUI has a hidden Deep Clean feature that removes not only cache, but also temporary system process files, which is not available on all models, but if it is, it is much more effective than standard cleaning.

How to find her:

1. Open the Security app (the shield icon).
2. Go to the Cleanup tab.
3. Slip on a Deep Clean (may be called Deep Clean).
4. Select RAM and start the process.

This function removes:

• 🗑️ Residual files of remote applications.
• 🧹 Cache of system services (for example, media.provider or downloadmanager).
• 🔄 Error logs and memory dumps that accumulate after crashes.

After deep cleaning, the phone can slow down for 1-2 minutes — which is normal, because the system needs to reassemble the cache of critical services.

5. Disconnecting unnecessary system processes

MIUI is known for its abundance of background processes, many of which can be safely disabled, such as analytics services, cloud backup services, or unnecessary system applications. Here is a list of safe processes to disable (checked at MIUI 14/15):

To disable unnecessary processes:

1. Activate Developer Mode (as described in Section 1).
2. Go to Settings → Additional → For Developers → Inactive Apps.
3. Select the app from the list above and click Disable.

⚠️ Warning: Disabling processes like com.miui.home or com.android.systemui will cause the interface to crash. The phone will work, but without the ability to interact with the screen, you will need to restart.

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

There are hundreds of apps on Google Play that promise to "free RAM in one click," most of them are dummy or malware, but there are some useful tools, and we tested 15 optimizers and selected the 3 most effective ones:

• 🏆 Greenify doesn't clean RAM directly, it freezes unnecessary applications, preventing them from running automatically. It requires root for full functionality, but it works without it.
• 🛠️ SD Maid removes residual files, cache and garbage processes. There is a feature CorpseFinder to find "dead" applications that occupy memory.
• 🔍 Simple System Monitor – shows detailed statistics of RAM usage and allows you to manually kill processes.

What not to do with SEOs:

• ❌ Do not install apps with names like this "RAM Booster Pro or Super Cleaner – these often contain advertising software.
• ❌ Do not give optimizers accessibility service (special capabilities) – this is the risk of data leakage.
• ❌ Do not believe the promise to “increase RAM” – physically it is impossible without an upgrade of iron.

💡

The best optimizer is your hands, and no app can clean your RAM more effectively than manually configuring your autoload and cache through system menus.

If you decide to use third-party software, check reviews from the past 2-3 months (many SEOs will go bad over time after updates). Also pay attention to the permissions the application requests – if the RAM cleaner requests access to contacts or SMS, this is a clear sign of fraud.

7. Radical methods: cache reset and update rollback

If standard methods have failed and the phone continues to slow down, it's time for radical measures, which take longer, but yield a noticeable performance boost.

Resetting the cache partition (wipe cache partition):

1. Turn off the phone.
2. Press the Power button + Volume up to enter Recovery Mode.
3. Select Wipe & Reset → Wipe Cache (Manage volume buttons, confirmation – power button).
4. Reset the device.

This procedure does not delete personal data, but clears the system cache, which can inflate up to 500 MB-1 GB.

Rejection of MIUI updates:

Sometimes the brakes appear after the firmware update, and if the problem has started recently, you can roll back to the previous version:

1. Download the old firmware for your model from the Xiaomi Firmware Updater website.
2. Rename the file to update.zip and place it in the root of internal memory.
3. In Recovery Mode, select Install update.zip.

⚠️ Warning: Firmware rollback erases all data (photos, contacts, messages) and backups first via Settings → Additionally. → Backup or Google Account.

8 Hardware Solutions: What to Do When Nothing Helps

If the software methods are exhausted and the RAM is still clogged, the problem may be hardware limitations.

• 🔄 Replacing firmware with custom (like LineageOS or Pixel Experience) will remove all unnecessary Xiaomi services, but will require unlocking the bootloader and fastboot skills.
• 🔋 Battery status check. Battery worn out (capacity) < 70%) may cause performance drawdowns due to processor frequency limitation.
• 🔧 Cleaning the RAM connector (relevant for older models like Redmi) 4X or Mi A1). Dust and contact oxidation can lead to memory reading errors.

For models with expandable memory (for example, POCO X3 Pro or Redmi Note 10 Pro can be used SWAP-It's not going to increase physical RAM, but it's going to create a paging file:

1. Install Root (for example, via Magisk).
2. At the terminal, run su dd if=/dev/zero of=/sdcard/swapfile bs=1M count=1024 mkswap /sdcard/swapfile swapon /sdcard/swapfile
3. Add /sdcard/swapfile swap swap defaults 0 0 to /etc/fstab.

This method is not recommended for everyday use — it speeds up microSD wear and can lead to data loss. Use it only in extreme cases.
