Xiaomi RAM Cleanup: A Complete Guide to Accelerating Your Phone

Why Xiaomi is starting to slow down and how it has to do with RAM

Have you noticed that your Xiaomi, Redmi or POCO are slowing down? Apps are slow to open, videos on social networks are hanging up, and games are starting to “float”? 90% of the time, overloaded RAM (RAM) is to blame. Even flagship models are faced with this problem over time — and it’s not about the “weak hardware”, but about the features of MIUI and background processes.

RAM is your smartphone’s desktop, where you temporarily store active application data. When RAM is clogged, the system has to constantly switch between tasks, which is what causes delays. For example, if you have 15 tabs open in Chrome, Telegram runs in the background, and you run Genshin Impact on top, the phone just can’t handle that load. But the good news is that you can clean up RAM on Xiaomi without drastic measures like factory resets.

In this article, we’ll look at 7 proven ways, from basic to advanced, including hidden MIUI features that aren’t known to everyone, and why automatic cleaning through the “Bust” often harms performance more than it helps.

Method 1: Manual cleaning through the “Recent” menu

The fastest method, which works on all models from the Redmi Note 10 to the Xiaomi 14 Ultra, requires no additional apps and takes less than 10 seconds.

How to do this:

• 📱 Open the Recent Apps screen (swipe up from the bottom edge of the screen with a delay in the middle).
• 🧹 At the bottom of the screen, find the Clean All button (or the basket icon). On some firmware, it is hidden - swipe left/right on the bottom panel.
• 🔄 If there is no button, click on the icon. ⋮ (three-point) → Clear everything.

This method closes all background processes, but has an important nuance: it resets the cache of only user applications. MIUI system services (such as Mi Share or Security) will continue to work in the background.

💡

If the phone brakes again after 5 minutes after cleaning the RAM, the problem is not in memory, but in congested storage. Check the free space in the Settings → Storage section (should be at least 10% of the total volume).

Method 2: Hidden Deep Cleanup in MIUI

Few people know, but MIUI has a built-in tool for forced cleaning of RAM that removes even system processes, and it's hidden in the developer menu, but you can turn it on without root rights.

Step-by-step:

1. Activate the Developer Mode: 🔧 Go to Settings. → The phone. 🔄 7 times press the version MIUI (A notification will appear saying, “You have become a developer»).

Settings → Additional → For Developers

🔄 Reboot the phone — RAM clean up automatically.

⚠️ Warning: This method aggressively closes all background tasks, including notifications from messengers. Use it only if the phone is completely inoperable.

Save important tabs in your browser |Close all messengers (notifications will disappear) |Switch off mobile Internet (if you clean due to overheating) |Remember passwords from applications (re-entry may be required)

Method 3: Using Built-in Booster (and Why It Doesn't Always Help)

MIUI Optimizer (or “Bust”) is Xiaomi’s proprietary memory cleaner tool that runs automatically when the screen is locked, but it can be called manually, but it has a serious drawback: the booster often skips system processes that eat up the lion’s share of RAM.

How to start the boost manually:

• 🛠️ Open the Security app (shield icon).
• 🔄 Click on the Optimization icon (or Boost in new versions).
• 📊 Wait for analysis and press Clean.

The problem is that the default booster doesn't touch:

• 📱 Google Play Services (can take up to 500MB) RAM).
• 🔄 Background tasks MIUI (For example, miui.analytics).
• 📶 Communication modules (mobile network, Wi-Fi, Bluetooth).

If the phone still brakes after the boost, go to method 4.

Method 4: Cleaning through ADB (for advanced users)

If standard methods do not help, you can resort to ADB-This is a way of connecting the phone to the computer, but it gives you maximum control over the processes. POCO F5, Redmi K60 and other smartphones on Android 12+.

What you need:

• 💻 Computer with installed ADB-driver.
• 🔌 USB-cable (preferably original).
• 📱 Included debugging by USB (Settings → For developers → Debugging by USB).

Commands for cleaning RAM:

adb shell


su




echo 3 > /proc/sys/vm/drop_caches # Clears the core cache




Killall -9 com.miui.securitycenter #Closing the security center




Am Kill-All Kills all User Processes

⚠️ Warning: The killall command is forced to shut down all applications, including system applications:

• 🔔 Notifications will stop before rebooting.
• 🔒 Re-entering passwords in some applications will be required.
• 📱 The phone can stay “freeze” for up to 30 seconds).

Method 5: Disabling Unnecessary System Applications

Many pre-installed MIUI applications work in the background, even if you don't use them. For example, Mi Video, Mi Music, GetApps or Mi Browser can take up to 300-400 MB of RAM in total. They can't be removed without root rights, but you can turn them off.

How to do this:

1. 🔧 Go to Settings. → Annexes → Application management.
2. 🔍 Click on three dots in the upper right corner → Show all the processes.
3. 🚫 Find unnecessary apps (e.g. com.miui.videoplayer for Mi Video).
4. 🔄 Click Disable (if the button is inactive, first click Stop).

List of safe applications to disable (do not delete system services!):

⚠️ Note: Do not disable apps with names:

• com.android. (Android system services),
• com.miui.home (launcher) MIUI),
• com.xiaomi.finddevice ("Find the device").

Disabling them can cause the phone to fail!

Method 6: Setup Auto-cleaning RAM with Game Turbo

If you play on Xiaomi, you know that games like PUBG Mobile or Call of Duty can take up to 1.5-2 GB of RAM. For gamers, MIUI has a hidden Game Turbo feature that optimizes memory specifically for games.

How to turn on:

• 🎮 Open the Settings. → Special facilities → Game Turbo (on some models, path: Settings) → Annexes → Game Turbo).
• 🔧 Turn on the switch Optimization of the game.
• 📊 Select Performance Mode (or Extreme Mode for Maximum Boost).
• 🔄 In the Memory Settings section, install Autoclean when you start the game.

Game Turbo does the following:

• 🎯 When you start the game automatically closes the background applications (except critical ones).
• 📈 Provides the maximum possible amount RAM play.
• 🔇 Disables notifications and background synchronization.
• 📡 Optimize the consumption of mobile traffic.

This method is especially useful for devices with 6-8 GB of RAM, where every megabyte counts. On flagships like Xiaomi 13T Pro or Redmi K70 Pro, the difference can reach 20-30 FPS in demanding games.

💡

Game Turbo only works for apps added to the list of games. To add the game manually, open it, then pull down the notification bar and click on the Game Turbo icon (as a gamepad).

Method 7: Reset partition cache (last chance before hard reset)

If none of these methods worked, and the phone continues to slow down, the problem may be the damaged cache, in which case the Wipe cache partition will help, which does not delete your data, but requires you to reboot to the receivers.

Instructions:

1. 🔄 Turn off the phone.
2. 🔧 Press the power button. + Volume upwards before the Mi logo appears (on some models – Volume upwards) + Loudness down + Nutrition).
3. 📱 You'll be taken to the Recovery menu. Use volume buttons for navigation, power button for selection.
4. 🔍 Choose Wipe & Reset → Wipe Cache.
5. 🔄 Confirm the action and wait for the completion.
6. 📱 Reboot the phone (Reboot) → Reboot to System).

⚠️ Warning: Don't confuse Wipe Cache with Wipe Data! The second option will completely reset the phone to factory settings, removing all data.

After the cache is dumped:

• 🔄 The first load can take up to 5-10 minutes.
• 📱 Some applications will require re-authorization.
• 📊 Productivity will return to factory (as after purchase).
