What is the RAM on Xiaomi: how to check and free RAM

The RAM on Xiaomi smartphones is one of the key resources that affect the speed of the system. If the device starts to slow down, applications spontaneously close or there are messages about a lack of memory, the first thought is to check what is occupied by RAM and what processes consume it. Unlike a PC, where it is enough to open the task manager, on MIUI and HyperOS, the memory management algorithms work differently: the system aggressively caches data, and background processes can take up to 70% of RAM even in standby mode.

In this article, we will discuss 5 working ways to check occupied RAM on Xiaomi, Redmi and POCO, including hidden developer tools, ADB commands and third-party utilities. Also explain why high RAM consumption does not always mean a problem - and in which cases it is worth sounding the alarm. The instructions are relevant for all modern firmware versions, from MIUI 12 to HyperOS 1.0.

1. Standard MIUI/HyperOS tools: Memory Manager

The easiest way to check your RAM is to use the built-in memory manager that is available in the system settings, which does not require root rights or PC connection, but only shows general statistics without detailing on the processes.

To open the dispatcher:

1. Go to Settings. → The phone.
2. Tap 5-7 times on the MIUI version (or HyperOS version) to activate the developer mode.
3. Return to the main settings menu and open the Additional → Special Features → Memory section (on HyperOS, the path may differ: Settings → Applications → Memory Management).

Here you will see a graph of the use of RAM in real time, as well as a list of top consumers (applications and system processes).

• 📊 Free Memory – How Much RAM Is Available for New Tasks.
• 🔄 Cache data – temporary files that the system can release when needed (this is normal!).
• ⚙️ System Processes – Android Core and Services MIUI, which cannot be closed by hand.

⚠️ Note: If you see unknown processes with names like com.android.XXX or miui.analytics on your list of top consumers, it's not always viruses. Many Xiaomi system services masquerade as random names. Before deleting, check the process through the list of secure services.

2. Hidden Tool: “Developer Mode” and Process Detailing

For deeper analysis, you can use hidden developer mode settings, where detail is available for each process, including PID (process identifier) and used memory in megabytes.

Algorithm of action:

1. Activate the Developer Mode (as described in the previous section).
2. Go to Settings → Additional → For developers.
3. Find Memory (or Services in Memory on HyperOS) and tap it.
4. At the top of the screen, select Average Usage in 3/6/12 hours to analyze the dynamics.

This menu displays:

• 📱 Applications – user programs (e.g. Telegram, Chrome).
• 🤖 Services – background processes of Android and MIUI.
• 🔍 Cache processes are inactive applications that the system can close when memory is scarce.

If you see a process with suspiciously high consumption (e.g. com.miui.daemon takes 1GB), this may indicate:

• 🐞 System Failure – Reboot the Device.
• 🦠 Virus – check with Google Play Protect or Malwarebytes.
• 🔄 Optimization Error – Reset Settings in Settings → Annexes → Resetting application settings.

Install antivirus (e.g. Malwarebytes)

ADB Commands: Professional Memory Analysis

For advanced users, the best way to diagnose is to use Android Debug Bridge (ADB), which allows you to get a complete list of processes indicating the exact consumption of RAM, as well as to identify hidden memory leaks.

Instructions:

1. Install ADB Tools on your PC.
2. Connect your smartphone to your computer and allow debugging over USB (Settings → Developers → Debugging over USB).
3. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell dumpsys meminfo

This command will produce a detailed memory usage report, including:

• MemTotal is the total amount of RAM.
• MemFree is a free memory.
• Cached is cached data.
• Apps – a list of applications with PSS (real RAM consumption).

To analyze a particular application (such as Facebook) use:

adb shell dumpsys meminfo com.facebook.katana

⚠️ Attention: Some processes MIUI (For example, com.miui.home can show high RAM consumption even in the background. This is normal for the Xiaomi shell, but if the value exceeds 500-700 MB, try resetting the launcher settings through Settings. → Annexes → Application management → Launcher.

4. Third-party utilities: top-3 RAM monitoring applications

If standard MIUI tools seem inadequate, third-party apps can be used, offering more visual graphics, high-load notifications, and even automatic memory cleanup.

Examples of Developer Quick Settings:

1. Install the app from Google Play.
2. Start and provide access to special features (Settings → Special features → Developer Quick Settings).
3. In the notification panel, a widget with a RAM graph will appear. Tap it for detail.

Warning: Avoid memory optimizers like Clean Master or DU Speed Booster. These apps often degrade performance by aggressively closing down background processes that Android could manage on its own. MIUI and HyperOS already have built-in optimization mechanisms — additional cleaners only get in the way.

💡

If you play heavy games frequently (like Genshin Impact or Call of Duty Mobile), add them to the optimization exceptions: Settings → Applications → Memory Management → Exceptions.

5. Memory dump analysis (for power users)

If the smartphone is rebooted regularly or produces an Out of Memory error, you may need to analyze the memory dump — a snapshot of the state of RAM at the time of failure, this method requires root rights or an unlocked bootloader.

Instructions:

1. Install Matlog or Logcat Extreme from Google Play.
2. Replay the problem (for example, run the application that causes the crash).
3. Immediately after the error, save the log through the application.
4. Look for lines in the log with lowmemorykiller or ActivityManager tags – they indicate a lack of RAM.

Example of critical log entry:

E/ActivityManager(1234): Low memory! No more background processes can run.


E/lowmemorykiller(1000): Kill 'u0_a123' (com.example.app), adj 900, size 512MB

If you see such messages, it means that:

• 🚨 The system is forced to close processes due to lack of memory.
• 🔧 Optimization required – remove unnecessary apps or increase the swap file (requires root).

⚠️ Note: On devices with HyperOS, the memory management mechanism has changed compared to the previous MIUI. Now, the system is more active in using zRAM, so dumps can contain fewer critical errors. kswapd0 High-loading is normal for HyperOS.

6. When is high RAM consumption normal?

Many users mistakenly believe that free RAM is good and busy is bad. In fact, Android (and MIUI in particular) was designed to maximize RAM by caching frequently used data, which speeds up the system!

Signs of normal RAM consumption:

• 📈 70–80% busy - typical of MIUI/HyperOS (system caches applications for quick start-up).
• 🔄 After closing the application, memory is not completely freed - Android keeps data in cache.
• 🎮 During the game, the RAM is loaded 90% - this is normal for heavy 3D-applications.

When you should be worried:

• 🐢 Smartphone brakes with 30-40% of memory occupied – possibly faulty RAM module.
• 🔥 Overheating + High RAM consumption by an unknown process – a sign of mining or a virus.
• 🔄 Constant reboots with Memory Leak error – diagnostics is required ADB.

💡

If you reboot your smartphone, you're 50 percent or more occupied immediately, that's OK. MIUI loads system services into memory to speed up your work, and the only thing that's telling you is that you're going to be getting a gradual increase in consumption for no apparent reason.
