How to view free RAM on Xiaomi phone: all ways

Why it is important to monitor RAM on Xiaomi

RAM is your smartphone’s “short memory” that determines how many apps can run simultaneously without hanging. On Xiaomi (including Redmi, POCO, and Black Shark models), even 8 to 12 GB of RAM can be clogged with background processes if the system is not optimized, such as messengers like Telegram or WhatsApp “eat” up to 300 to 500 MB each, and games like Genshin Impact or Call of Duty Mobile require 1.5 to 2 GB just to run.

If the phone starts to slow down, spontaneously close applications or warm up — the first reason that is worth checking is the lack of free RAM. Many users mistakenly confuse RAM with internal storage (where photos, videos and files are stored).

Spoiler: on new models with MIUI 14/15 and HyperOS, the RAM control algorithms are smarter, but manual control is still useful. For example, on the Xiaomi 13 Pro with 12 GB of RAM, the system can reserve up to 4 GB for background tasks, leaving the user only 8 GB - and this is normal if you do not play heavy games.

Method 1: Through a standard task manager

The fastest method is to use a built-in Task Manager, which shows not only the list of running applications, but also the current load of RAM. Instructions are relevant for all Xiaomi smartphones on MIUI or HyperOS (including Redmi Note 12, POCO X5, Xiaomi 14, etc.).

How to open it:

1. Click on the “Recent Apps” button** (square or swipe up with a 1 second delay).
2. At the bottom of the screen, you'll see a memory-use panel. Click on it.
3. The Task Manager section will open with detailed statistics.

What you'll see:

• 📊 Total RAM (for example, 6 GB or 8 GB).
• 🔄 Memory used (in megabytes or gigabytes).
• ⚡ Free memory is a key indicator.
• 📱 List of active applications with an indication of how much memory each consumes.

Close unnecessary applications (swipe aside)

Check which programs consume >500 MB

Pay attention to background processes (e.g., app updates)

Reboot your phone if you are free <10% RAM-->

⚠️ Warning: Do not close system processes like com.android.systemui or miui.guardprovider, which can cause the interface to crash or reboot the device: MIUI It optimizes background tasks itself, and manual intervention can only impair performance.

Method 2: Through phone settings (About the phone section)

If the task manager doesn't show enough data, you can look into the hidden system settings, which is suitable for all models, including the old (Redmi 4X, Mi A2) and new (Xiaomi 13T, POCO F5).

Step-by-step:

1. Open the settings (cog icon).
2. Go to About the Phone (or About the Device on some firmware).
3. Tap 5-7 times on the MIUI version (or HyperOS build number) until you become a developer!
4. Return to the main Settings menu and open a new section for developers (or Advanced Settings → Developers).
5. Scroll down to the Debugging block and find Memory or Memory Use.

Here you'll see:

• 📈 Timeline of using RAM in real time.
• 🔢 Average consumption in recent years 3/6/12 hours.
• 🛠️ List of processes, indicating PID (process identifier) and memory consumption.

⚠️ Note: If you enable the option to Do Not Save Actions (or Do Not Keep Active) in the Developer section, the system will aggressively close the background applications. This can increase free RAM, but also impair multitasking (for example, YouTube Music will stop when switching to another app).

Method 3: Using secret codes (USSD and engineering menu)

For advanced users, there are hidden service codes that open up technical information, which work on most Xiaomi smartphones, but some models (such as the POCO M6 Pro or Redmi 12C) can be disabled.

Basic codes for checking RAM:

• 📞 ##4636## - opens the test menu, where you can see the memory usage in the Usage statistics section.
• 🔧 ##225## - shows a memory usage calendar (not working on all devices).
• 📊 ##36446337## - An alternative way to open memory information (relevant to older models on the computer) MIUI 10–12).

How to use:

1. Open the Phone app.
2. Enter the code as if you were dialing a number.
3. Press the call button.
4. In the menu that opens, select Memory or RAM.

⚠️ Note: Do not change the settings in the engineering menu unless you understand their purpose! For example, the Set max background processes option allows you to manually limit the number of background processes, but an incorrect value can lead to permanent reboots.

Once a week.

Only when the phone is slowing down.

Never checked.

Method 4: Third-party applications for monitoring RAM

If standard MIUI tools aren't enough, you can install specialized utilities that not only show the current state of memory, but also help optimize memory usage.

Top.-3 applications:

• 📱 CPU Monitor -- shows the use of RAM, CPU and battery in real time. There's a widget for the home screen.
• 🛠️ DevCheck – gives full information about the iron, including the type of RAM (LPDDR4X, LPDDR5) and its clock speed.
• 📊 Simple System Monitor – a lightweight application with day/week memory usage schedules.

How to use (as in DevCheck):

1. Install the app from Google Play.
2. Open it and go to the Memory tab.
3. Note the following: Total RAM is total. Available RAM is free memory. Used RAM is memory used. Cached RAM is cache-occupied memory (it can be released without harm to the system).

💡 Useful tip: DevCheck can enable low memory notifications, such as setting an alert when less than 1 GB of RAM is free.

💡

If you play heavy games often, install Xiaomi’s Game Booster app, which automatically clears RAM before starting the game and blocks background processes that eat up resources.

Method 5: Through ADB (for advanced users)

If you know how to work with ADB (Android Debug Bridge), you can get the most detailed information about the state of RAM, this method is suitable for diagnosing problems at the system level, for example, if the phone spontaneously restarts or crashes applications.

Instructions:

1. Install. ADB-computer-driver.
2. Turn on USB debugging on your phone (Settings → About Phone → MIUI Version → 7 taps → For developers → USB debugging).
3. Connect your phone to your PC and type in the command line: adb shell dumpsys meminfo
4. For simplified output, use: adb shell cat /proc/meminfo

Free remain ~4-5 GB – this is enough for comfortable work.
