How to Free RAM on Xiaomi Phone: Effective Methods for All Models

Your Xiaomi, Redmi or POCO started to slow down, applications spontaneously close, and the task manager says "RAM is 90% full"? The problem is not that you have a weak smartphone - even flagship models with 12 GB of RAM eventually begin to "choke" from background activity. In this article, we will analyze 7 proven ways to free RAM without radical measures like resetting to factory settings.

The reasons for the clogged memory on Xiaomi fall into two categories: system (related to the MIUI firmware and its features) and user (installed applications, cache, background processes). For example, even after a game like Genshin Impact or Call of Duty Mobile closes, some of its data may remain in RAM due to aggressive caching, and applications like Facebook, TikTok or AliExpress can eat up to 500-800 MB of memory in the background.

It's important to understand that MIUI (especially versions 13-14) is using RAM to speed up multitasking. That's okay if you have 1-2 GB of free memory, but when you have less than 500 MB of free memory, the phone starts to hang. Then you have concrete solutions, from simple to advanced.

1. Manual cleaning of RAM through Task Manager

The fastest way to free up 300 to 1,000 MB of memory is to force you to close your unwanted applications, and MIUI has a built-in tool to do this:

  1. Open the settings (cog icon).
  2. Go to the Appendix section β†’ Task Manager.
  3. Click on the "Clean" icon (broom in the lower right corner).
  4. For deep cleaning, tap Clean everything (even system processes will be removed, but will not harm the phone).

This method has an immediate effect, but it works temporarily β€” after 10-15 minutes, the background applications will load RAM again.

πŸ’‘

If there is no β€œClean” button in the Task Manager, add it through Settings β†’ Screen β†’ Navigation Panel β†’ Additional buttons.

  • ⚑ Pros: Works on all models (Redmi Note 10, POCO X3, Xiaomi 13, etc., does not require superuser rights.
  • ⚠️ Cons: only cleanses user processes, system services (Google Play Services, MIUI Daemon) remain active.

2. Disable Autoboot Applications

Many programs (Vkontakte, Yandex.Maps, SberBank Online) automatically start when you turn on your phone or after you reboot, even if you did not open them, which is one of the main reasons for the constant lack of RAM.

To prohibit autoloading:

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Select an app (such as TikTok) and tap AutoRun.
  3. Turn off the "Allow Auto Start" slider.

For mass shutdown, use the "Energy Saving" mode:

  • πŸ”‹ Go to Settings. β†’ Battery and productivity β†’ Energy conservation.
  • πŸ“± Select the Apps Select and mark those that shouldn’t work in the background.
πŸ“Š What application most often β€œeats” RAM on your Xiaomi?
Social media (VK, Instagram)
Messengers (Telegram, WhatsApp)
Games (PUBG, Genshin)
System Processes (MIUI, Google Services)
Other

⚠️ Warning: Disable autoboot for Google Play Services or MIUI System can cause phone malfunctions. Don't touch the system apps with the icon. MI.

3. Limitation of application background activity

Even after closing, many programs continue to run in the background, consuming RAM and battery power. MIUI has a hidden setting that allows you to limit this activity.

Instructions:

  1. Open Settings β†’ Applications β†’ Application Management.
  2. Select an app (such as AliExpress) and go to Permissions.
  3. Find the "Background Activity" item and select Limit.

For mass restriction:

  • πŸ› οΈ Use the settings. β†’ Battery β†’ Performance mode β†’ Choice of applications.
  • πŸ“‰ Tag applications that should not consume resources in the background (e.g. Wildberries, Ozone).
AnnexAverage RAM consumption (background mode)Recommendation
Facebook400-700 MBLimit background activity
Telegram200-350 MBDisable Media Autoboot
Google Chrome300-500 MBClose tabs after use
MIUI System800 MB-1.2 GBDo Not Touch (Critical Process)

πŸ’‘

Limiting background activity for the 5-7 most voracious applications could free up to 1.5GB of RAM in the long run.

4.Cache and garbage cleanup via MIUI Optimizer

MIUI has a built-in garbage cleaner, MIUI Optimizer (formerly called Security), which deletes temporary files, app cache, and frees up RAM. Here's how to use it:

  1. Open the Security app (shield icon).
  2. Put the cleaning (broomstick).
  3. Press "Deep Clean" and wait for the scan to be completed.
  4. Select Clear (deletes cache, residual files, unnecessary data).

For maximum effect:

  • 🧹 Enable the RAM Cleanup option in the same menu.
  • πŸ—‘οΈ Repeat the procedure regularly (every 2-3 days) as this prevents the accumulation of garbage.

Important: Deep Cleaning removes the cache of all apps, so some programs (such as Instagram or YouTube) will take longer to load when they first run.

5. Use of the "Light" mode (lightweight firmware)

Starting with MIUI 12, Xiaomi added a hidden β€œLight” mode that optimizes the system for weak devices or phones with low RAM (2-4 GB), which turns off some animations, reduces memory consumption by system processes and limits background activity.

How to turn on:

  1. Go to Settings. β†’ The phone.
  2. Tap 5-7 times on the MIUI version until the notification β€œYou became a developer!” appears.
  3. Go back to the Settings β†’ Additional β†’ Developer settings.
  4. Find the option "Light" and activate it.
  5. Reboot the phone.

Effects of activation:

  • βœ… Free RAM will be 300-600 MB more.
  • βœ… Increase battery life (by 10-15%).
  • ❌ Some Visual Effects (MIUI-animations) will be disabled.
What models support the Light mode?
The mode is available on all devices with MIUI 12 and newer, but the most noticeable effect on smartphones with 2-4 GB of RAM: Redmi 9A, POCO M3, Xiaomi Mi A3. On flagships (Xiaomi 12 Pro, Redmi K50) the difference is minimal.

6. Disconnecting unnecessary system services

MIUI contains many background services that are rarely used but are constantly hanging on RAM, such as Mi Cloud Sync, Xiaomi Service Framework or MSA (Mi System Ads), which can be safely disabled.

Method 1: Through ADB (without root rights)

  1. Connect your phone to your PC and enable USB Debugging (Settings β†’ About Phone β†’ MIUI β†’ 5 taps β†’ Developer Options β†’ USB Debugging).
  2. Download ADB Tools and open the command line in the folder with adb.exe.
  3. Enter a command to disable an unnecessary service (example for MSA):
adb shell pm disable-user --user 0 com.miui.systemAdSolution

List of safe services for disabling:

  • πŸ“‘ com.miui.analytics – Xiaomi Analytics Collection.
  • ☁️ com.xiaomi.cloud – Mi Cloud (if you don’t use the cloud).
  • πŸ“’ com.miui.systemAdSolution - Advertising System MSA.

⚠️ Warning: Do not disable services called google, android or miui.core, this will cause your phone to fail. ADB backup!

7. reset partition cache (without data loss)

If previous methods didn’t work, try resetting the /cache partition cache.This won’t delete your files or apps, but will clear temporary system data, which can take up to 1-2 GB of RAM.

Instructions:

  1. Turn off the phone.
  2. Press the Power button + Volume up until the Mi logo appears.
  3. From the Recovery menu, select Wipe & Reset β†’ Wipe Cache (manage volume buttons, confirmation – power button).
  4. After cleaning, restart the phone (Reboot β†’ System).

This method helps if:

  • 🐒 The phone stopped after the update. MIUI.
  • πŸ”„ Applications spontaneously close or fly out.
  • πŸ“± Task Manager Hangs Unknown Processes With High RAM Consumption.

1. charge the phone at least 50%

2. make a backup copy of important data (photos, contacts)

3. remember passwords from accounts (Mi Account, Google)

4. Make sure there is enough free space on the phone (minimum 1 GB)-->

FAQ: Frequent questions about RAM on Xiaomi

❓ Why after cleaning the RAM after 5 minutes, the memory is clogged again?
This is normal MIUI behavior. The system aggressively caches frequently used applications to speed up their launch. If there is less than 500 MB of free memory, try disabling autoboot for unnecessary programs (section 2 of the article).
❓ Can I increase the RAM on Xiaomi with a memory card?
No, it's a myth. MicroSDs are only used to store files (photos, videos, music) but can't expand RAM. The only way to increase RAM is to buy a phone with a larger capacity (e.g., Redmi Note 12 Pro+ with 12GB instead of 6GB).
❓ Which apps load the most RAM?
Top.-5 "sluggish "apps" according to the version MIUI Optimizer: Facebook - up to 1 GB in the background. TikTok β€” 600–900 MB. Google Chrome β€” 400–700 MB (especially with a lot of tabs). Instagram β€” 300–500 MB. PUBG Mobile/Call of Duty - before 1.5 GB even after closing, it is recommended to limit their background activity (section) 3 articles).
❓ Why After Updating MIUI It's less free RAM than it is?
Newer versions of MIUI (especially 13-14) are optimized for multitasking but require more resources. For example, MIUI 14 reserves up to 2 GB of RAM for system processes. Solution: Turn on Light mode (section 5).
❓ How to check which application loads RAM?
Use the built-in monitor: Open Settings β†’ Applications β†’ Task Manager. Tap three dots in the top right corner and select Show System Processes. Sort the list by column RAM (in descending order). Applications with consumption of more than 200 MB in the background are candidates for restriction.
