How to Free RAM on Xiaomi: The Complete 2026 Guide

Your Xiaomi, Redmi or POCO has started to slow down, apps spontaneously shut down, and the task manager says “Not enough memory”? The problem is overloaded RAM. Even flagships with 12 GB of RAM accumulate background processes, cache and “junk” tasks that eat up resources. In this article, unique RAM cleaning methods adapted for MIUI 14/15 and Android 13/14, including hidden features and automation.

We won’t recommend the trivial “close unnecessary apps” or “reboot your phone”; instead, you’ll learn how to:

• 🔍 Find and kill hidden processes that are not visible in the standard task manager
• ⚡ Use built-in tools MIUI, Which 90% of users don’t know
• 🤖 Automate RAM cleaning without manual control
• 🛠️ Optimize the system for models with 4–6 GB RAM (including the Redmi Note 10/11, POCO X3/X4)

All methods are tested on current firmware and do not require root rights or factory reset. If your smartphone is released after 2019, the instruction will be 100%. For older models (Xiaomi Mi 8, Redmi 5), check the MIUI version in the comments.

1. Diagnostics: how to check the RAM load on Xiaomi

Before you clean up your memory, you need to understand what it's doing. MIUI has two ways of monitoring, standard and advanced, and standard shows only active applications, and extended shows all processes, including system.

To open extended monitoring:

1. Go to Settings. → The phone.
2. Tap 5 times on the line version of MIUI to activate the Developer Mode.
3. Back to Settings → Additionally. → For developers.
4. Find the Memory option and turn it on.
5. Now in the notification panel will appear a schedule of RAM use with details on the processes.

Here's what the categories in the graph mean:

Critical values:

• 📱 4GB RAM: Free must be at least 500-700 MB.
• 📱 6-8 GB RAM: free - 1-1.5 GB.
• 📱 12+ GB RAM: If it is less than 2 GB, there is a problem.

⚠️ Attention: If after cleaning the RAM, free memory is instantly eaten again - a virus or malware is operating in the system. → Security → Scan.

2. Hidden MIUI functions for RAM cleaning

Xiaomi is embedding optimization tools in firmware that it doesn't advertise. You can find them through Settings → Special Features → System Acceleration (some models have a different path).

• 🧹 Deep Cleanup: removes not only cache, but also temporary files of system applications (for example, Mi Video or Music).Do not use more than 1 time a week - can reset the settings of some applications.
• ⚡ Background optimization: Limits background activity for selected apps (e.g. Facebook or Instagram won’t eat RAM in the background).
• 🔄 Autoclean: customizable timer for automatic RAM cleaning (e.g. every evening at 2:00).

How to turn on auto-cleaning:

1. Open Settings → Applications → Autorun.
2. Slip on three dots in the top right corner and select Memory Cleanup.
3. Set a schedule (we recommend 1-2 times a day).
4. In the list of exceptions leave only messengers (WhatsApp, Telegram) and banking applications.

For models with MIUI 14+, the function Advanced optimization is available:

⚠️ Attention: POCO F3/F4 redmi K50 In global firmware, Deep Optimization may not be available. If it's not, update it. MIUI Up to the latest version or install EU-firmware (informal).

3. Manual cleaning of RAM: what can be killed and what can not

If automatic methods don't work, you'll have to clean the RAM manually, but it's important not to overdo it: By killing critical processes, you can cause the phone to restart or the interface to crash.

Safe list of processes to clean (via Settings → Apps → All Apps):

• 🎮 Games: PUBG Mobile, Genshin Impact, Call of Duty – even in the background they take 300-500 MB of RAM.
• 📺 Social networks: TikTok, Instagram, Facebook – hold up to 700 MB of memory for each.
• 🎵 Musical applications: Spotify, Yandex Music, Mi Music - caching tracks in RAM.
• 🗺️ Maps: Google Maps, Yandex.Navigator, 2GIS — After closing, up to 200 MB of memory is left.

Processes that should NOT be killed:

• 🚫 com.android.systemui - interface MIUI (If you kill him, you get a black screen).
• 🚫 com.miui.home – launcher (without it there will be no desktop).
• 🚫 com.android.phone – telephone services (network will disappear).
• 🚫 Any process called miui or xiaomi.

For manual cleaning:

1. Open the Settings → Applications.
2. Tap it on three points. → Show all the processes.
3. Sort by RAM usage.
4. Select an unnecessary application → Stop it.

Close all games and social media

Stop the background processes of maps and music

Check free memory (should be ≥ 30% of total RAM)

Do not touch system services with the name Miui or Xiaomi

Restart the phone after cleaning-->

For advanced users, if you're confident in your actions, you can use ADB to force cleanup.

adb shell am kill-all


adb shell cmd activity clear-top

But remember, this will kill all user processes, including unsaved data in apps.

4. Optimization for weak smartphones (4–6 GB of RAM)

If you have a Redmi 9A, a POCO M3, or another budget phone with 4GB of RAM, standard cleaning methods may not help.

• 📉 Turn off animation: go to Settings → For developers, set all three animation settings to animations disabled, which will speed up work by 15-20%.
• 🗑️ Remove duplicate files: Use the built-in Security app → Cleaner → On public sector employees, duplicates can take up to 1 GB of memory.
• 🔄 Use lightweight versions of applications: Facebook Lite, Messenger Lite, Twitter Lite take 2-3 times less RAM.
• 🛑 Limit background activity: in Settings → Battery. → Battery Optimization Select Strict Mode for all applications except instant messengers.

For models with 6 GB of RAM (Redmi Note 10 Pro, POCO X3 NFC), virtualization of RAM will help:

1. Install RAM Expander from Google Play (Android 11+ is required).
2. Allocate 1-2 GB of internal memory for virtual RAM.
3. Reboot the phone.

⚠️ Cons of the method: virtual memory works slower than physical, but will help to avoid crashes of applications.

💡

On Xiaomi with 4GB of RAM, turn off secondary cameras in Settings → Camera → Additional → Use the main camera. This will free up to 200MB of RAM, which is usually reserved for processing photos from wide-angle and macro modules.

5 Automation: How to clean RAM without manual control

Keeping up with memory is tedious. Fortunately, MIUI and Android have tools for automatic cleaning. Here are the best ways to do this:

• ⏰ Tasker + AutoTools: Create a task that will clear RAM when you lock your screen or connect to Wi-Fi. Example of condition: Profile: Screen off Task: Shell → input keyevent 3 (Back button to close applications)
• 🤖 MacroDroid: Free application with ready-made macros to clean RAM. Select a trigger (like low battery charge) and action Clean Memory.
• 📱 Built-in planner MIUI: Settings → Battery. → Planner → Memory cleanup. Set up to start every 6 hours.

For MIUI 15 users, the Smart Cleaning function is available:

1. Go to Settings → Memory → Smart Cleaning.
2. Enable the option Adaptive Cleaning.
3. Select the priority: Performance (aggressive cleaning) or Battery (sparing mode).

Important: Automatic cleaning may conflict with:

• 🎮 Background games (such as Brawl Stars or Clash Royale).
• 📱 Applications for tracking activity (Google Fit, Mi Fitness).
• 🔊 Musical players with background playback.

💡

Automatic RAM cleaning is convenient, but it can interfere with multitasking. Set up exceptions for critical applications (messengers, navigators, music).

6. Radical Methods: When Nothing Helps

If you've tried everything, but the RAM is still clogged, it's time for radical measures, which require caution, but work even on heavily littered smartphones.

• 🧹 Reset partition cache (does not delete data, but cleans system debris): Turn off the phone. Press the power button + Volume up to enter Recovery. Select Wipe Cache Partition. Reboot.

Back to factory firmware

Attention.

Removal of Bloatware

ADB

adb shell pm uninstall --user 0 com.miui.weather2


adb shell pm uninstall --user 0 com.xiaomi.scanner




adb shell pm uninstall --user 0 com.miui.videoplayer

A list of safe packets to remove can be found on the XDA Developers forum (see your phone model).

Last chance: even if the reset didn't work, the problem could be hardware wear. On smartphones older than 3-4 years, RAM degrades and its real volume decreases. You can check this through the AIDA64 app (Memory → RAM section). If less is available than specified in the specs, it's time to think about replacing the phone.

⚠️ Note: Xiaomi with Snapdragon processors 6xx/7xx (For example, Redmi Note 9 Pro, POCO X3) After resetting the partition cache, the speaker may lose sound. This is treated by rebooting or resetting the settings. → Sound.

7. Prevention: how to prevent RAM clogging

It's better to keep the memory from overloading than to clean it up later. Here are 5 rules that will keep the RAM in order:

• 🚫 Do not install memory cleaners from Google Play (such as Clean Master or Google Play). DU They themselves cause lags, taking up to 300 MB of RAM.
• 🔄 Update your firmware every 1-2 months. MIUI Optimize memory management (e.g., in the MIUI 15 added Memory Fusion algorithm, which combines RAM and ROM for temporary tasks).
• 📱 Use the “Lite” versions of applications: Facebook Lite, Twitter Lite, Spotify Lite take up 2-3 times less memory.
• 🔋 Turn off "Adaptive Brightness" in Settings → Display. This feature constantly monitors sensors, taking up to 100 MB of RAM.
• 🎮 For gamers: in Settings → Special facilities → In turbo mode, turn on the option of Memory Cleanup on exit. This will close all background processes after the game.
