Cleaning RAM on Xiaomi Redmi: from manual methods to hidden MIUI features

Your Xiaomi Redmi is slowing down, apps are spontaneously shutting down, and animations are twitching? 90% of the time, itโ€™s overloaded RAM. Even on new models like the Redmi Note 13 Pro+ with 12GB of RAM, MIUI can not manage resources effectively โ€” especially if youโ€™re actively multitasking or running heavy games like Genshin Impact.

In this article, 7 proven ways to clean RAM, from basic to advanced, including hidden features MIUI, We'll look at how to free up memory without documenting it. ROOT-You know, right, which apps to remove first, and why the standard booster in the curtain doesn't always work, and then finally, answers to a lot of questions, including the myths about the RAM optimizers from Google Play.

Why Xiaomi Redmi RAM is clogged faster than other smartphones

Xiaomiโ€™s performance is often affected by two key features of MIUI firmware:

  • ๐Ÿ”„ Aggressive app cache: The system stores background data longer than stock Android to speed up re-runs.
  • ๐Ÿค– "Hidden System Services: Functions like miui.analytics, com.xiaomi.mipicks or com.miui.hybrid consume up to 300-500MB of RAM even in the background.
  • ๐ŸŽฎ Optimization for games: On models with Snapdragon chipsets (for example, Redmi) K60) Adreno drivers reserve part of RAM for graphics, reducing the available volume for applications.

In addition, on devices with 4-6 GB of RAM (such as Redmi 9A or Redmi Note 10), MIUI limits the number of background processes to 16-20, but does not optimize their priorities, as a result, messengers like Telegram or WhatsApp can be unloaded from memory more often than heavy games.

โš ๏ธ Warning: If the phone still brakes after cleaning the RAM, check the use CPU In Settings โ†’ The phone. โ†’ System status: High CPU load (over 70%) at low RAM load indicates a virus or firmware failure.

Method 1: Manual cleaning through the notification curtain

The fastest but least effective method is suitable for emergency release of 200-400 MB of RAM:

  1. Pull down the notification curtain (swipe from the top edge of the screen).
  2. Click on the "Clean" icon (brush) in the upper right corner.
  3. Confirm the action by tapping "Clean [X]MB".

This method only covers visible background processes, but does not affect MIUI system services and kernel cache, for example, after such a cleanup, applications like Facebook or TikTok can reappear in the active process list in 1-2 minutes.

๐Ÿ’ก

To see the actual state of RAM before and after cleaning, install the Simple System Monitor app from Google Play, which shows detailed real-time memory usage statistics, including "hidden" processes.

Method 2: Deep Cleaning with Security App

The built-in security app (com.miui.securitycenter) offers a more powerful RAM control tool than a curtain. Here's how to use it:

  1. Open the Security app (the shield icon).
  2. Go to the "Speed Boost" section.
  3. Press "Deep Clean" and wait for analysis.
  4. Remove the boxes from apps you donโ€™t want to close (such as a music player or navigator).
  5. Slip "Clear [X] processes."

This method removes up to 60 percent of the background processes, including some system processes, but it doesn't affect:

  • ๐Ÿ”’ Secure processes (e.g. com.android.phone for communication).
  • ๐Ÿ“ฑ Notification apps (e.g. Viber with unread messages).
  • ๐Ÿ”„ Services MIUI, Topics, Cloud and Analytics.

Save important data from the clipboard

Close all active calls or broadcasts

Disable VPN (may block the work of "Security")

Check the battery (process consumes up to 5% of the charge)-->

Method 3: Disable Auto-Run Unnecessary Applications

Many apps (especially Chinese ones) automatically start when you turn on your phone or connect to the Internet, taking up RAM. You can turn them off via a hidden menu:

  1. Go to Settings โ†’ Applications โ†’ Application Management.
  2. Slip on three dots in the upper right corner and select "Stop".
  3. Sort the list by "Last Launch."
  4. Turn off autoplay for apps you rarely use (e.g. Mi Video, Mi Browser, GetApps).

Note the following processes โ€“ they often hang in RAM without needing:

AnnexRAM consumption (in the background)Can I turn it off?
com.miui.weather2120โ€“180 MBYes (unless you use the weather widget)
com.xiaomi.midrop80-130 MBYes (unless you use Mi Drop)
com.miui.player150โ€“220 MBYes (if you use another player)
com.android.vending (Google Play Store)200-350 MBNo (critical for updates)

โš ๏ธ Warning: Do not disable auto-run for com.google.android.gms (Google Services) and com.miui.home (Launcer) and this will cause the system to crash and the need to restart.

Method 4: Use of the Game Turbo mode

Game Turbo, originally designed for gamers, can optimize the use of RAM for all applications, and it activates as follows:

  1. Open Settings โ†’ Special Opportunities โ†’ Performance Mode.
  2. Turn on the "Performance Mode" switch.
  3. Select a โ€œBalancedโ€ or โ€œExtremeโ€ profile.
  4. In the "Memory Optimization" section, activate "Real-time background cleanup".

In extreme mode, the system will automatically close background processes when the foreground takes up more than 70% of RAM, useful for devices with 4-6 GB of memory (for example, the Redmi 9T or Redmi Note 10 Pro), but can lead to:

  • โณ Delays in switching between applications (as they are unloaded from memory).
  • ๐Ÿ”” Missed notifications (if messenger is closed).
  • ๐Ÿ”‹ Increased battery consumption (due to frequent process restarts).

Method 5: Clean RAM through ADB (for advanced users)

If standard methods don't work, you can manually kill unnecessary processes through ADB (Android Debug Bridge), which requires connecting the phone to a PC, but allows point-to-point memory management.

Instructions:

  1. Install ADB Tools on your computer.
  2. Enable USB debugging on your phone: Settings โ†’ About Phone โ†’ MIUI version (tap 7 times), then Settings โ†’ Additional โ†’ For Developers โ†’ Debugging over USB.
  3. Connect Redmi to your PC and execute in the command line:
adb shell


su




cmd appops set com.miui.securitycenter android:kill_background_processes allow

Now you can manually kill processes with the command:

adb shell am kill-all

To pinpoint the removal of a particular app (e.g. Facebook):

adb shell am force-stop com.facebook.katana
List of dangerous ADB commands that can damage the system
Do not do it without understanding the consequences! 1. adb shell pm uninstall -k --user 0 [packet] โ€“ removes the system application without the possibility of recovery. 2. adb shell setprop ro.zygote.disable_gl_preload True โ€“ Breaks Graphic Rendering. 3. adb shell rm -rf /data/dalvik-cache โ€” Deletes the Dalvik cache, the phone will not boot.

Method 6: Reset partition cache (without data loss)

If RAM is clogged because of a damaged system cache, resetting the cache partition will help. This will not delete your files or applications, but requires a reboot in Recovery Mode.

  1. Turn off the phone.
  2. Press the power button + volume up until the Mi logo appears.
  3. In the recovery menu, select "Wipe & Reset" (use volume buttons for navigation).
  4. Slip "Wipe Cache" and confirm the action.
  5. Restart the device ("Reboot").

After this procedure:

  • โœ… Free up to 1-1.5 GB of RAM (by cleaning the cache of the core and Dalvik).
  • โšก App launches will be accelerated (as the cache will be rebuilt).
  • โš ๏ธ The first turn on after the reset will take 3-5 minutes (the system restores the cache).

๐Ÿ’ก

Resetting partition cache is the only official way to clean the system cache that does not require ROOT-It's safer than a factory reset, but less effective in serious lags.

Method 7: Optimize RAM through hidden developer settings

The Developer Menu contains settings that limit background processes and force unused applications out of memory, to activate them:

  1. Go to Settings โ†’ About Phone โ†’ MIUI version and tap it 7 times until the notification โ€œYou became a developer!โ€ appears.
  2. Back to Settings โ†’ Additionally. โ†’ For developers.
  3. Find and turn on:
  • ๐Ÿ”„ "Limit background processes" โ†’ Select โ€œMaximum 2 Processesโ€ (for 4 GB of RAM) or โ€œMaximum 4 Processesโ€ (for 6โ€“8 GB).
  • ๐Ÿ—‘๏ธ "No maintenance" โ†’ This will force the system to force applications to close when they leave (savings RAM, but increases startup time).
  • โšก "Forced. GPU-acceleration" โ†’ can reduce the load on RAM due to the graphics processor (but increases battery consumption).

These settings will significantly reduce multitasking, but will help on weak devices (such as the Redmi 8A or Redmi 9C). On flagships like the Redmi K70 Pro, they are not recommended to use โ€“ they will only worsen performance.

FAQ: Frequent questions about cleaning RAM on Xiaomi Redmi

โ“ Why after cleaning the RAM, the phone begins to brake even more?
This is because of the cold start effect. When you force all processes to close, the system has to re-upload data to RAM the next time an application is launched. On weak processors (like the Snapdragon 439 in Redmi 9), this takes longer than saving from cleaning. Solution: Use the cleanup selectively (like just for games or a browser), rather than for all processes at once.
โ“ Can I increase RAM on Xiaomi Redmi with a memory card?
No, it's a myth. Xiaomi's RAM Expansion technology uses internal memory (UFS) rather than microSD. Moreover, on most Redmi models (except flagships like the Redmi K60 Ultra), this feature is disabled by default, because it impairs performance. If you have RAM Extension in your settings, activating it will give you +1-2 GB of virtual memory, but it will not replace physical RAM.
โ“ Which apps eat the most RAM on the RAM MIUI?
According to the analysis 10 000 devices (source: XDA Developers, 2023), top-up-5 "RAM on Xiaomi Redmi: Facebook (up to) 500 MB in the background. Mi Browser (300โ€“400 MB due to the built-in news cache. @TikTok (250โ€“350 MB even after closing. Google Play Services (200โ€“600 MB, critical to Android running.Theme Manager (com.android.themes, 150โ€“250 Tip: Replace Mi Browser with Chrome or Firefox โ€“ they consume on 30โ€“40% less RAM.
โ“ Is it true that the โ€œradiation optimizersโ€ from Google Play help?
No, most of these applications (e.g. Clean Master, DU Speed Booster) are empty. They: Use the same commands as the built-in Security utility. Show false notifications about the "critical state" of memory. They themselves hang in RAM, consuming up to 100-150 MB. Except for Simple System Monitor (for monitoring only) and Greenify (for manual control of background processes, but requires ROOT on new versions of Android).
โ“ How to check how much RAM is available on my Redmi?
The built-in MIUI tools show inaccurate data. To find out the real state of memory: Install Termux from Google Play. Enter the command: cat /proc/meminfo | grep -E 'MemTotal|MemFree|Buffers|Cached' Result: MemTotal is the total amount of RAM. MemFree is completely free memory. Buffers + Cached is memory that can be released without loss of performance. If MemFree + Buffers + Cached is less than 20% of MemTotal, it's time to clean RAM.
