How to clean up RAM on Xiaomi Redmi: from simple ways to hidden MIUI features

Your Xiaomi Redmi is slowing down, apps are spontaneously shutting down, and there are a dozen background processes in the Task Manager? It's all because of the loaded RAM. Even top-end models like the Redmi Note 12 Pro+ or Redmi K60 accumulate waste processes that eat up resources over time. But don't rush to drop the phone to factory settings - 90% of the time, the problem can be solved software-based.

In this article, we will discuss 7 proven methods of cleaning RAM, from basic (available even to a beginner) to advanced (including hidden MIUI features and development teams). Particular attention will be paid to the unique features of Xiaomi that are not on smartphones of other brands, for example, built-in memory accelerator and optimization for game modes. All methods are tested on current versions of MIUI 14/15 and adapted for the models of 2020-2026.

1. Quick cleaning through Task Manager

The most obvious, but often underrated, way is to manually close the background apps, which is not the way it is done on naked Android in MIUI, so many users miss key nuances.

Open the multitasking menu (swipe upwards with a delay of 0.5 seconds). Here you will see two groups of applications:

• 🔄 Active – working at the moment (they can not be closed by swipe).
• 📱 Frozen – suspended by the system, but occupy RAM.
• 🚫 Systemic processes MIUI (They are usually hidden, but can be seen through the developer’s settings).

To close the application:

1. Swipe the card upwards (for normal applications).
2. For "stubborn" processes (e.g. com.miui.home), click on the app icon and select Close.
3. For mass cleaning, tap on the basket icon (will appear after the swipe to the left).

💡

If there is no cart icon in the multitasking menu, include it in Settings → Special Features → Gestures → Show the clean button.

⚠️ Note: Do not close system processes like Android System or MIUI Daemon can cause the phone to restart or sensors to fail, and it is optimal to leave 1-2 active apps (e.g., messenger and music player) behind).

2. Built-in "Memory Accelerator" in MIUI

Xiaomi has added a unique tool to the firmware, the Memory Booster, which automatically optimizes the use of RAM, which works in the background, but can be manually run for instantaneous effect.

How to activate:

1. Go to Settings → About the phone → Memory.
2. Slip on Clear (if the button is inactive, the memory is already optimized).
3. For deep cleaning, press Memory Accelerator → Optimize Now.

💡

The memory accelerator is most effective on budget models with 3-4 GB of RAM. On flagships (8+ GB), its impact is minimal, since the system itself manages resources.

3. Cleaning the application cache (including system)

Cache is a temporary file that apps save to make things faster, accumulating over time and taking up not only internal memory but also RAM (if the cache is loaded into the RAM), clearing the cache won’t delete your data, but it can reset the settings of some applications (for example, login games).

Instructions:

1. Go to Settings → Applications → Application Management.
2. Select the app (start with the most voracious ones – Facebook, Instagram, PUBG Mobile).
3. Slip the vault. → Clear the cache.
4. For system applications (such as Launcher or Security), first click Three Dots → Show System.

⚠️ Note: Do not clear the cache for:

• 🏦 Banking applications (SberBank Online, Tinkoff) – this can lead to the blocking of the account.
• 📱 Android System WebView – responsible for displaying web pages in applications.
• 🎮 Online Game Savings (Genshin Impact, Honor of Kings).

4. Disconnect autoload and background activity

Many apps run automatically when you turn on your phone or after you reboot, even if you don’t use them, and this is one of the main reasons for Xiaomi’s persistent RAM shortage.

How to prohibit autoloading:

1. Open Settings → Applications → Application Management.
2. Select the application → Autostart → Disable the slider.
3. For mass shutdown, use Settings → Battery and Performance → Autostart Management.

Also limit background activity:

1. In the same application management menu, select Battery → Background activity.
2. Install Restricted for unnecessary applications (such as AliExpress or Wildberries).

5.Use of the performance mode (Game Turbo)

Xiaomi has added Game Turbo to the firmware, which not only optimizes gaming performance, but can also free up RAM for normal tasks, a feature that is available even on budget models like the Redmi 10A.

How to activate:

1. Open Settings → Special features → Game Turbo
2. Turn on the memory optimization slider.
3. Choose Balanced (for everyday tasks) or Performance (for gaming).

Game Turbo operates in two ways:

• 🎯 Background cleaning – when you start a resource-intensive application (game, video editor), the system automatically closes unnecessary processes.
• 🔄 Dynamic RAM Distribution – Redistributes memory between active tasks.

💡

Game Turbo is most effective on models with 6+ GB of RAM. On phones with 3-4 GB, it can, on the contrary, cause slowdowns due to aggressive cache cleaning.

6. Reset MIUI settings (without data loss)

If previous methods didn’t work, try a soft reset of MIUI settings. This won’t delete your files or apps, but will return system settings to factory values, which often solves problems with “memory leaks.”

Instructions:

1. Go to Settings → About the phone → Reset settings.
2. Select Reset MIUI (not to be confused with a full reset!).
3. Confirm the action and wait for the reboot (takes 2-3 minutes).

After discharge:

• 🔧 Reset the Memory Accelerator and Game Turbo.
• 🔒 Update all apps on Google Play (outdated versions may conflict with the Google Play app). MIUI).
• 📱 Restart the phone again – this will help the system stabilize the use of RAM.

⚠️ Attention: After resetting settings MIUI may throw off:

• 🎨 Theme and wallpaper.
• 🔔 Notification settings for applications.
• 🔕 Application permissions (access to camera, microphone, etc.).

7. Advanced methods (for experienced users)

If you're willing to go beyond standard settings, here are some advanced ways to optimize RAM that require technical knowledge and can affect system stability.

Method 1: Change the swappiness parameters

The swappiness setting determines how actively the system uses the swap file. Xiaomi defaults to 60, which leads to frequent use of virtual memory instead of RAM, which can be reduced to 10–30 for more efficient resource management.

Instructions (require root or ADB):

adb shell su


echo 10 > /proc/sys/vm/swappiness

Method 2: Disabling unnecessary system services

MIUI has a lot of background services that you can safely disable, like:

• 📊 com.miui.analytics – Analytics collection (can be turned off without consequences).
• 📡 com.xiaomi.scanner - scanner QR-codes (if not used).
• 🎵 com.miui.player is a standard music player.

To disconnect via ADB:

adb shell pm disable-user --user 0 com.miui.analytics

Method 3: Use of an alternative launcher

The standard MIUI launcher (com.miui.home) consumes up to 300-500MB of RAM even in the background, and replacing it with a Nova Launcher or Lawnchair could free up additional resources.

⚠️ Attention: Before use ADB or change of system parameters:

• 🔋 Charge your phone at least 50%.
• 📱 Make a backup copy through Settings → Additionally. → Backup.
• 🔧 Make sure you have the latest drivers installed. ADB (version no less than 33.0.3).
