How to clean up RAM on Xiaomi Poco X3: From Handheld Methods to Hidden Functions MIUI

Xiaomi Poco X3 (version NFC Pro and Pro – one of the most popular smartphones in the budget segment with powerful hardware: Snapdragon processor 732G, Up to 8 GB of RAM and 128 GB of ROM. However, even such characteristics do not save from the typical problem of Android – clogging of RAM with background processes, application cache and unoptimized settings. MIUI. If your Poco X3 began to slow down, overheat or spontaneously close applications, the reason most likely lies in the overloaded RAM.

In this article, we will analyze 7 proven ways to clean RAM - from basic (available even for beginners) to advanced (using hidden functions). MIUI and ADB). You'll find out how:

• 🔍 Identify applications that eat RAM using built-in tools
• ⚡ Free Memory Without Root Rights and Data Loss
• 🛠️ Set up auto-cleaning to prevent future hangings
• ⚙️ Optimize MIUI 12/13/14 Poco-specific X3

All methods tested on Poco X3 firmware MIUI 12.5–14 (including global and Chinese versions) If your smartphone is running on an older version, update the software first via Settings → The phone. → Updating the system.

1. How to check the RAM load on Poco X3

Before you clean up RAM, you need to understand what's loading it. X3 There are two ways to monitor:

Method 1: Built-in monitor MIUI

1. Open the Settings. → The phone.
2. Tap 5-7 times on the MIUI version until the notification “You became a developer!” appears.
3. Return to the main settings menu and go to Additional → For developers.
4. Find the Debugging section → Memory monitor and turn it on.
5. Now in the notification panel will appear a schedule of the use of RAM in real time.

Method 2: Security menu

• 📱 Open the Security app (Icon with shield).
• 🔍 Go to the Accelerator tab.
• 📊 Here you can see the current RAM load, the list of active processes and the possibility of their forced closure.

Note the apps that take up more than 300-500MB of RAM in the background, which are the potential culprits of the brakes, most commonly messengers (Telegram, WhatsApp), social networks (TikTok, Instagram) and games (Genshin Impact, PUBG Mobile).

💡

If you see the process of com.miui.home with consumption in the memory monitor >500 MB is normal for you. MIUI. Do not force it to close, otherwise the launcher will reboot.

2 Manual closing of background processes

The fastest way to free RAM is to force the shutdown of unnecessary applications, but it must be done carefully so as not to disrupt the system.

Instructions:

1. Open Recent Apps (swipe up with 1 second delay).
2. Scroll through the list of open applications.
3. Close them one at a time, swipe up. Don't use the "Close All" button, which may cause the launcher to reboot.

What can be closed without risk:

• 🎮 Games (if you don’t play right now).
• 📷 Photo/video processing applications (CapCut, Lightroom).
• 📺 Streaming services (YouTube, Twitch, Netflix).

What NOT to close:

• ⚠️ Settings (com.android.settings).
• ⚠️ Security (com.miui.securitycenter).
• ⚠️ System interface MIUI (com.miui.home).

⚠️ Warning: If it restarts immediately after the application is closed, it means it has been added to the autoload. → Annexes → Manage Auto-Run and Disable Unnecessary Programs.

3. Clean RAM through the "Safety" menu

Annex Security in the MIUI It has a built-in memory optimization tool called the Accelerator, which not only closes the background processes, but also clears the cache, which has a double effect.

Step-by-step:

1. Open the Security app (the shield icon).
2. Go to the Accelerator tab.
3. Press the Clean button (at the bottom of the screen).
4. Confirm the action if a request appears.

After cleaning, you will see:

• 📉 Reducing RAM load by 20-40%.
• 🚀 Accelerating the opening of new applications.
• 🔋 Possible decrease in processor temperature (if previously there were freezes).

However, this method has two disadvantages:

1. Cleaning is temporary – after 10-15 minutes, the background processes will start again.
2. Some apps (like Facebook) may start consuming even more RAM after a restart.

💡

Use the "Accelerator" no more than 1 time in 2-3 hours. Frequent cleaning can lead to increased battery consumption due to constant restarts of processes.

4. Optimization of autoloading and background activity

Many applications on Poco X3 They're defaults to add to the startup and work in the background, even if you're not using them.

How to turn off autostart:

1. Go to Settings → Applications → Autostart Management.
2. Select an app from a list (such as AliExpress or Likee).
3. Turn off the switches: 🔄 Auto-start 📱 Background activity 🔔 Display notifications (optional)

Applications that can be safely disabled:

After you turn off autoboot, restart your smartphone. This is necessary for the changes to take effect. After 1-2 days, check the RAM load - it should decrease by 20-30% in average use.

⚠️ Warning: Do not disable auto-start for system applications MIUI (For example, com.miui.securitycenter or com.android.phone, this can result in loss of mobile network or broken notifications.

5.Use of the "Game Turbo" mode to control RAM

Poco X3 It is equipped with the function "Game Turbo" (Game Turbo), which not only optimizes performance in games, but also allows you to manually control the distribution of RAM.

How to turn on and configure:

1. Open Settings → Special features → Game Turbo
2. Activate the Game Turbo switch.
3. Start any game (for example, PUBG Mobile or Call of Duty).
4. Call the Game Turbo panel by swiping your finger from the right edge of the screen inward.
5. Click on the icon. ⚡ Cleaning up memory.

Advantages of this method:

• 🎯 Cleaning is selective – only those processes that are not necessary for the game are closed.
• 🔄 RAM is released instantly, without rebooting.
• 📊 The Game Turbo panel displays the current download CPU/GPU and RAM.

If you’re not playing, but want to use Game Turbo to clean up your memory, run any “light” game (like 2048 or Subway Surfers) and do the same.

Advanced methods: ADB and hidden settings MIUI

If the standard methods do not help, you can use hidden functions. MIUI team-wise ADB. These methods require a little more effort, but give the maximum effect.

Method 1: Limitation of background processes through ADB

This command reduces the number of background processes that the system can run:

adb shell settings put global bg_process_limit 2

Where 2 is the maximum number of background processes.

• 📱 2 - minimum RAM consumption (can close messengers).
• 📱 3 – Balance between productivity and savings.
• 📱 4 is the standard value for Poco X3.

Method 2: Disabling animation (speeding up the interface)

Animations in MIUI Not only do they slow down the interface, they also take up RAM:

adb shell settings put global window_animation_scale 0


adb shell settings put global transition_animation_scale 0




adb shell settings put global animator_duration_scale 0

To return animations, replace 0 with 1.

Method 3: Hidden Menu of Memory Testing

V MIUI There's a hidden menu for testing RAM:

1. Dial the code in the phone app: ##36446337###.
2. Choose. RAM Test.
3. Wait for the test to be completed (1-2 minutes).

If the test shows errors (Fail), this may indicate hardware problems with RAM (for example, after a phone drops).

⚠️ Attention: Teams ADB may disrupt some functions MIUI, If entered incorrectly, make a backup copy through Settings before experimenting. → Additionally. → Backup and reset.

7. Radical methods: cache reset and factory settings

If all previous methods have not helped, radical measures remain:

Method 1: Cleaning the cache of the section

This method does not delete your data, but resets temporary system files:

1. Turn off your smartphone.
2. Press the power button. + Loudness up before the logo appears POCO.
3. In the Recovery menu, select Wipe cache partition (manage volume buttons, confirmation - power button).
4. After cleaning, select Reboot system now.

Method 2: Reset to factory settings

This is the last chance if RAM is clogged due to viruses, incorrect updates or system errors.

• 📤 Make a backup copy through Settings → Additionally. → Backup and reset → Local backup.
• 🔐 Make sure to remember the password from your Mi Account (required after resetting).
• 📱 Charge your phone at least 50%.

For discharge:

1. Go to Settings → About the phone → Reset settings.
2. Select Erase all data (reset to factory settings).
3. Confirm the action and wait for the reboot (5-10 minutes).

After the Poco dump X3 It will be as new as the new one, but all data (photos, messages, apps) will be deleted. RAM will return to its original state, and you can reconfigure the phone to avoid previous errors.

💡

Factory reset is a last resort, and in 90% of cases, RAM problems can be solved by the methods in the previous sections, and only use reset if the phone has stopped responding to commands or is infected with a virus.
