1. How to check the download RAM Xiaomi

Before you can clear a memory, you need to understand what's overloading it. MIUI HyperOS has built-in monitoring tools, but they are hidden from the average user.

The easiest way is:

1. Open the Settings. → The phone.
2. Tap 5-7 times on the line MIUI Version (or HyperOS Version) until the notification “You became a developer” appears.
3. Return to the main settings menu and go to Additional → For developers.
4. Find the Debugging section → Memory usage (or process statistics in new versions).

Here you'll see:

• 📊 Total volume RAM and accessible memory.
• 🔄 List of active processes with memory consumption (in MB).
• ⚠️ Warnings about apps that 'eat up' the most resources.

💡

If you see unknown names on the process list (e.g. com.android.abc.xyz), don't rush to stop them. These may be system services that are essential for a stable phone.

For more detailed analysis, use third-party utilities like DevCheck or Simple System Monitor (available on Google Play).

• 📈 Loading schedule RAM real-time.
• 🔋 The effect of applications on the battery (often “gluttonous” programs discharge the phone and simultaneously load memory).
• 🗑️ Cache volume of each application.

2. Quick cleaning RAM rootless

If your Xiaomi is starting to slow down right now, use the built-in tools that don't require superuser rights and work on all models.

Method 1: Cleaning button in the latest app menu

The most obvious, but often ignored method is:

1. Click on the square button (or swipe from the bottom up and hold your finger on the screen) to open a list of recent apps.
2. At the bottom of the screen, find the Clean Everything button (or the broomstick icon). 🧹).
3. Slip on it – the system will close all background processes, except for system ones.

This method releases up to 30-50% RAM, But the effect is temporary: in 10 to 15 minutes, the memory will be full again. Why? MIUI aggressively caches frequently used apps (such as WhatsApp, Telegram, Mi Browser) so they open faster.

Method 2: Cleaning through “Security”

The Security app (or Security in global firmware) has a built-in optimizer:

1. Open the Security app (Icon with shield) 🛡️).
2. Go to the Optimization (or Boost) tab.
3. Click Clear Memory (or Deep Clean).
4. Confirm the action if the system requests permission.

This is a deeper method than just cleaning the app menu. It removes:

• 🗑️ Background process cache.
• 🧹 Unnecessary temporary files.
• 🔄 «Hangover” tasks that have not closed correctly.

Method 3: Reboot the phone

It's a banal but effective method.

• ✅ All RAM is cleared (except for the core of the system).
• ✅ Temporary files and cache are reset.
• ✅ Closes the “hang” processes that are not removed manually stop.

How to properly reboot Xiaomi:

1. Press the power button for 2-3 seconds.
2. In the menu that appears, select Reboot (not Shut down!).
3. Wait 30–60 seconds (on older models it can take up to 2 minutes).

⚠️ Warning: If your phone doesn't restart for longer than 5 minutes, it could indicate a serious firmware or iron problem. + up volume for 10-15 seconds for forced reboot.

3. Optimization of application autoloading

Many apps are automatically launched when you turn on your phone or when you restart. RAM, Disabling the autoboot can free up to 1-1.5 GB of RAM on a regular basis.

How to turn off autoboot:

1. Go to Settings → Applications → Application Management.
2. Select the Autoboot tab (or Auto-start in global firmware).
3. Sort the list by Last Start to see the most active programs.
4. Turn off autoboot for unnecessary apps (such as games, social networks, which you rarely use).

Examples of applications that can be safely disabled:

• 🎮 Games (PUBG Mobile, Genshin Impact, Call of Duty – they take so long to load, they do not need to boot up).
• 📱 Social networks (Facebook, TikTok, Instagram – they already notify you of new messages via push).
• 🛒 Shops (AliExpress, Wildberries, Ozon) – they don’t have to hang in the background all the time).

⚠️ Note: Do not disable autoboot for system applications with names like com.android.systemui, com.miui.home or com.google.android.gsf. This can lead to unstable phone operation or complete loss of functionality (for example, notifications disappear or launcher stops working).

These settings will reduce the load on RAM, but they have side effects:

• 🔄 Applications will open longer when first run (since cache is not saved).
• 🔔 Some notifications may be delayed.
• 🎮 Games can be slowed down when switching between them.

6. Clearing the cache and application data

The app cache takes up not only internal memory, but also operational memory, and many programs (especially games and social networks) are stored in the computer. RAM If the cache inflates, it can eat up hundreds of megabytes of memory.

How to clear the cache:

adb shell am kill-all

Method 2: Disconnection MIUI Optimization

MIUI Optimization is a service that manages background processes, sometimes it doesn't work properly and overloads. RAM. To turn it off:

1. Activate Developer Mode.

3. Reboot the phone.

💡

Shutdown MIUI Optimization can cause some features to work unstable (such as dark theme or navigation gestures).If you notice bugs, return the settings to their original state with settings put global. miui_optimization_disabled 0.

Method 3: Using Tasker for Automatic Cleaning

Tasker allows you to create automatic tasks, such as cleaning. RAM on a schedule or with a low level of free memory.

Example of cleaning task RAM:

1. Create a new task in Tasker.
2. Add the action of Run Shell.
3. Enter the command: echo 3 > /proc/sys/vm/drop_caches (Root rights are required).

What not to do during cleaning RAM

Many of the "advice" on the Internet not only doesn't help, but it also hurts your phone.

• 🚫 Use a cleaner like a cleaner or DU Speed Booster. These apps are self-consuming. RAM, Show false notifications about a “critical download” and often contain advertising software. MIUI already has built-in cleaning tools – no additional utilities are needed.
• 🚫 Disable all background processes manually. Some system services (mediaserver, android.process.acore) are critical to the operation of the phone, and stopping them will lead to system failure or endless restart.
• 🚫 Install Magisk modules for “optimization» RAM. Many modules (e.g, RAM Expander) promise to “increase” RAM due to internal storage, but in practice this leads to a slowdown due to the use of slow flash memory instead of fast memory. RAM.
