Cleaning RAM on Xiaomi Redmi: a complete guide to speed up the smartphone

Your Xiaomi Redmi has started to slow down, apps spontaneously shut down, and interface animations twitch? Most likely, the problem lies in overloaded RAM. Even the powerful Redmi Note 12 or Redmi K60 series models face a lack of RAM over time due to background processes, cache and voracious applications. Unlike internal memory, which can be expanded with a microSD card, RAM requires regular cleaning.

In this article, we’ll look at 5 proven ways to clean up RAM, from standard MIUI tools to hidden features for power users. You’ll learn how to free up memory without root rights, which apps eat up the most resources, and why manual cleaning through the developer menu is more effective than automatic optimization from Xiaomi. All methods have been tested on Redmi 9/10/11, Note 8/9/10/11/12 and K40/K50/K60 with MIUI 12-14 firmwareware.

1. Quick cleaning through the notification panel

The easiest way to free up RAM is to use the built-in Memory Cleanup feature in the notification curtain, a method that is suitable for emergency cases where the phone starts to brake right while playing or working with the application.

How it works:

1. Swipe your finger down to open the notification panel.
2. Find the "Cleanup" icon (usually depicted as a broomstick or a memory graphic).
3. Slip on it - the system will close all background processes, except active ones.

• ✅ Pros: Instant effect, does not require a reboot.
• ❌ Cons: cleans only part of the processes, after 10-15 minutes the memory will be filled again.
• 🔄 Frequency of use: 1-2 times a day with active use.

⚠️ Warning: If the phone starts to brake even more after cleaning, it is a sign that one of the applications (most often messengers or launchers) automatically restarts and takes up memory).

2. Deep cleaning through security settings

MIUI has a hidden security tool that not only cleans the RAM, but also analyzes which applications consume the most resources, a method that is more effective than standard curtain cleaning.

Step-by-step:

1. Open the Settings. → Security.
2. Select Clean Up (or Optimize in newer versions of MIUI 14).
3. Click Clear Memory – the system will show you a list of active processes.
4. Tap Clean everything or manually select unnecessary processes.

After cleaning, it is recommended to restart the phone - this will help reset the cache of the core and free up an additional 100-300 MB of RAM. On models with 8/12 GB of RAM (for example, Redmi K60 Pro), the effect will be less noticeable, but still useful for system stability.

3 Manual process control through the developer menu

For advanced users who want full control of RAM usage, MIUI has a hidden developer menu that allows you to manually stop processes, limit background activity, and even change the memory limits for applications.

How to turn on the developer menu:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version (you will be notified "You became a developer").
3. Return to the main settings menu – there will be a new section for developers.

Now you can control RAM:

• 🛑 Stopping Processes: In the For Developers section → You will see a list of all active processes in the services, where you can manually stop unnecessary processes (for example, com.miui.daemon or background tasks of messengers).
• 🔧 Limitation of Background Processes: B For Developers → Process limit can be set to the maximum number of background tasks (recommended Standard limit or No background processes for weak models).
• 📊 Memory monitoring: Turn on the option to Show CPU usage - a real-time RAM load schedule will appear in the notification curtain.

⚠️ Warning: Don’t stop processes with names like android., media. or surfaceflinger, which are system services that your phone won’t work without. Also avoid manually controlling RAM on 4GB models. RAM or less – this can lead to frequent reboots of applications.

Close all active applications | Make a backup of important data | Remember the names of system processes (don't stop!) | Connect your phone to charge (in case of freeze)

4. Optimization of Auto-Run Applications

One of the main reasons for RAM overload is when you auto-start your phone or connect to the Internet, such as Facebook, TikTok or AliExpress, can automatically run background processes even if you haven’t used them in a long time.

How to turn off autostart:

1. Go to Settings → Applications → Application Management.
2. Select an app (like Instagram) and tap AutoRun.
3. Disable all switches: Auto Start, Secondary Start, and Show notifications.

The list of the most voracious applications (according to the tests on the Redmi Note 11 Pro+):

• 📱 Social networks: Facebook (up to 400 MB in the background), TikTok (up to 300 MB), Instagram (up to 250 MB in the background).
• 💬 Messengers: Telegram (up to 200 MB with active chats), WhatsApp (up to 150 MB).
• 🎮 Games: PUBG Mobile, Genshin Impact and Call of Duty Mobile can take up to 1 GB of RAM even after closing.
• 🛒 AliExpress, Wildberries and Ozon store up to 180MB of push notifications.

💡

After turning off auto-start, restart your phone – this will help reset the app cache and free up an additional 10-15% of RAM.

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

There are hundreds of apps on Google Play that promise to "magic" clean RAM with one tap: CCleaner, DU Speed Booster, Clean Master, and others. But most of them are not only useless, but also harmful - they consume resources themselves and show false notifications about the "critical state" of the phone.

If you still want to try a third-party optimizer, choose only proven ones:

• 🔹 Greenify (requires root or ADB) — suspends background processes without deleting data.
• 🔹 SD Maid (paid version) – clears the cache and residual files that take up RAM.
• 🔹 Simple System Monitor – shows detailed statistics of memory usage without unnecessary cleanings".

⚠️ Note: On Xiaomi models with MIUI 13/14 Many SEOs are blocked by the system because of security policies. If the application doesn't work after installation, check the permissions in Settings. → Special permits → Display Pop-up and Auto Launch.

Alternative to third-party programs - built-in memory monitor in MIUI:

1. Open Settings → About the phone → System status.
2. Stick Memory – here you can see detailed statistics on each process.
3. Click Clean next to unnecessary apps.

Hardware methods: reboot and cache reset

If the software methods don’t help and the phone still slows down, try hardware methods – they reset temporary data that can take up RAM.

Method 1: Forced resetting

• Press the Power + Volume button for 10-15 seconds.
• After vibration release the buttons - the phone will restart.
• This method cleans up to 30% of the RAM that was occupied by “hang” processes.

Method 2: Recovery cache reset (does not delete personal data!)

1. Turn off the phone.
2. Press Power + Volume Up until the Mi logo appears.
3. From the Recovery menu, select Wipe & Reset → Wipe Cache.
4. Confirm the action and restart the phone.

These methods are especially effective on models with 6/8 GB of RAM (for example, Redmi K50 Gaming or Redmi Note 12 Pro+), where after resetting the cache is released up to 1-1.5 GB of memory. On weak devices (for example, Redmi 9A with 2 GB of RAM), the effect will be less noticeable, but still useful for stability.

💡

Regular reboot (1 every 2-3 days) helps prevent RAM fragmentation and reduces the risk of freezes by 40% (according to tests by Xiaomi Lab).

7. Prevention: how to prevent overloading of RAM

The best way to keep RAM in order is to keep it from filling. Here are 5 preventative measures that will prolong the life of your Xiaomi Redmi:

• 🚫 Do not install memory cleaners - they themselves cause the brakes.
• 🔄 Update. MIUI — In new versions, the management of RAM is optimized (for example, in the MIUI 14 added a Memory Extension mechanism that uses part of internal memory as virtual RAM).
• 🎯 Use the "Lite" version of the application: Facebook Lite, Messenger Lite, Twitter Lite consume 2-3 times less memory.
• 🔋 Turn off unused functions: Bluetooth, GPS and NFC in the background take up to 100 MB of RAM.
• 📱 Periodically check the "Sleepy" applications in Settings → Battery → Sleep mode – they continue to work in the background, even if you do not use them.

On models with 12 GB of RAM (such as the Redmi K60 Ultra), these measures are not as critical, but they are still useful for long-term stability. However, owners of budget Redmis with 3-4 GB of RAM (such as the Redmi 10A or Redmi 9C) should pay special attention to prevention.
