Your Xiaomi has become slow, applications spontaneously close, and interface animation twitches? 90% of the time, overloaded RAM is to blame. Even the flagship models of Redmi, POCO or Mi with 8-12 GB of RAM eventually begin to “suffocate” from the background processes. But don’t rush to reset the phone to factory settings – we have collected 7 proven ways to clean up RAM, which will return your device performance.
In this article, you will find not only standard methods like manual cleaning through the menu, but also hidden MIUI features, development teams, and optimization tips that will help reduce the load on RAM by 30-50% after the first application. All instructions are relevant for MIUI 14/15 and adapted for the models of 2020-2026 (including Redmi Note 12 Pro+, POCO F5, Xiaomi 13T, etc.).
Why is RAM clogged on Xiaomi and how it manifests itself
Xiaomi’s RAM is based on the principle that the more free the better. When the amount of free RAM falls below 15-20%, the system begins to force applications to close, which causes:
- 🔄 Re-boot of games (Genshin Impact, PUBG Mobile) or instant messengers (Telegram, WhatsApp).
- ⏳ Hanging when switching between tasks (for example, when returning to Chrome after watching YouTube).
- 📉 A sharp drop FPS in games or "supposing" interface MIUI.
- 🔋 Increased battery consumption due to constant process reboot.
The main reasons for overloading RAM:
- Background: MIUI aggressively caches apps even when you don't use them, like Mi Video or Mi Browser, which can hang in the background for months.
- Autoboot: Many apps (especially Chinese ones) are added to autoruns without your knowledge.
- Viruses and Advertising: Some APK-files from third-party sources create hidden services that eat RAM.
- System Errors: MIUI 14/15 has a bug that sometimes leaks the com.miui.home process and takes up to 1GB of memory.
⚠️ If after cleaning the RAM free memory again falls to 0 in 5-10 minutes - this is a sign of hardware failure (chip wear and tear). RAM) In this case, only flashing or repairing will help.
Method 1: Manual cleaning through the “Safety” menu
The simplest method that works on all Xiaomi smartphones regardless of the MIUI version is suitable for emergency cleaning, but does not solve the problem of background processes.
Instructions:
- Open the Security app** (Shield icon).
What's cleansing:
- 🗑️ Application cache (temporary files).
- 🧹 Unnecessary background processes.
- 📱 Residual data of remote programs.
Do not close the security menu for more than 30 seconds.|Check if the game or heavy app is running (e.g., video editor)|Restart your phone and try again.|Update the Security app via Google Play-->
This method frees up 200-500 MB of RAM, but the effect is temporary - after 1-2 hours, the memory will be refilled.
Method 2: Disabling Auto-Run Unnecessary Applications
Many applications (especially system from Xiaomi) automatically start when you turn on the phone and hang in the background, consuming RAM.
How to do this:
- Slip on the three dots in the top right corner and select "Stop."
| Annex | Can I turn off autostart? | Saving RAM |
|---|---|---|
| Mi Video | ✅ Yes. | 80–120 MB |
| Mi Browser | ✅ Yes. | 100–150 MB |
| Google Play Services | ❌ No (critical process) | — |
| Clean Master (if installed) | ✅ Yes. | 150-200 MB |
| Facebook/Instagram | ⚠️ Partially (notifications will not work) | 200-300 MB |
After you turn off autostart, restart your phone. This will free up to 1 GB of RAM and reduce battery load.
💡
If the autorun list doesn’t have the right app, try disabling it through Settings → Apps → [App Name] → Battery → Background Activity and select “Limit.”
Method 3: Using Developer Mode to Optimize RAM
The hidden developer settings allow you to manually limit background processes and force you to close unnecessary applications, a method that requires caution but produces maximum effect.
How to turn on the developer mode:
- Go to Settings. → The phone.
- Tap 7 times on the item "Version" MIUI»** (A notification will appear saying, “You have become a developer»).
- Return to the main settings and open a new section “More → For developers”.
Now we will optimize the RAM:
- 🔧 Process Limitation: In the Applications section, select Background Process Limit and set Process Maximum 2** (this will reduce multitasking but free up the process). RAM).
⚠️ Warning: Do not disable system processes called com.android. or com.miui. – this can lead to system failure and the need to flash the system.
Once a day.|Once a week.|Only when the phone starts to brake|Never clean.-->
Method 4: Clean RAM through ADB (for advanced users)
If standard methods don’t work, you can manually kill unnecessary processes through Android Debug Bridge (ADB), a technique that requires a PC and a little technical skill, but gives you complete control over memory.
Instructions:
- Download ADB Tools and unpack the archive.
- On your phone, turn on “Debugging by USB”** (Settings → For developers → Debugging by USB).
adb devices
adb shellNow you can use the commands to clean:
- 📊 View the use of RAM: dumpsys meminfo
- ⚡ Forced to close the process (e.g. Facebook): am force-stop com.facebook.katana
- 🧹 Clear cache of all applications: pm trim-caches 1000000000
List of popular stop packages:
| Annex | Packet name | Team stop |
|---|---|---|
| com.facebook.katana | am force-stop com.facebook.katana | |
| com.instagram.android | am force-stop com.instagram.android | |
| Mi Browser | com.android.browser | am force-stop com.android.browser |
What if the ADB can’t see the device?
Method 5: Optimization through cleaner applications (top)-3 Xiaomi)
If you don't want to go through the settings, you can use third-party utilities, but be careful, many cleaners are the ones that cause the brakes themselves. We tested the top 3 apps that actually work on MIUI.
Utilities rating:
- Greenify (paid version) 🔹 Hybernation of unnecessary applications (complete freezing of background processes). 🔹 It works without root rights. 🔹 Saves up to 40% RAM and 20% battery.
- SD Maid 🔹 Removes system debris and cache. 🔹 It has an automatic cleaning scheduler built in. 🔹 Supports cleaning Dalvik-cache (accelerates application launches).
Simple System Monitor
- 🔹 Shows detailed statistics of the use of RAM in real time.
- 🔹 Allows you to manually “kill” processes.
- 🔹 Lightweight (does not load the system).
What does it do:
- 🛠️ Deletes temporary system files that may be causing memory leaks.
- 🔄 Correcting mistakes MIUI, RAM-related.
- 📈 Releases 100-300MB RAM by optimizing background services.
