How to check RAM on Xiaomi: a complete guide to the diagnosis of RAM

Introduction: Why it is important to monitor the state of RAM on Xiaomi

RAM is the brain of your Xiaomi smartphone, which determines the speed of applications, multitasking and overall performance of the device. Over time, even on top-end models like the Xiaomi 14 Ultra or the other. POCO F6 Pro can cause problems: applications start to “fly out”, the system slows down, and the battery runs out faster than usual.

Unlike permanent memory (ROM), Where files are stored, RAM is responsible for the time data of active processes. If memory is clogged or damaged, the smartphone starts to “glut”: from random reboots to full freeze, especially for low-end models of Redmi with 4-6 GB of RAM, where every megabyte counts. In this article, we will analyze how to check the state of RAM on Xiaomi without special tools and with them – from built-in functions. MIUI professionally.

It’s important to understand that the problems with RAM are not always obvious, for example, on Xiaomi smartphones with Snapdragon 8 Gen 2 processors (for example, Xiaomi). 13T Pro) Memory degradation can only occur at high loads, such as during games or video rendering, so it is worth making regular diagnoses, especially if you notice at least one of the "symptoms" of the malfunction.

Signs of problems with RAM on Xiaomi

Before you rush to check RAM, make sure your smartphone really needs a diagnosis. Here are the key signs to watch out for:

• 🐢 Slowdown: applications open for a long time, animations “brake”, although before everything worked smoothly.
• 🔄 Spontaneous reboots: The phone suddenly turns off and turns on, especially when running heavy apps (games, video editors).
• 🗑️ Closing background processes: messengers or music players “fly out” of memory, despite the free resources.
• 🔋 Increased battery consumption: if the battery began to sit down 20-30% faster for no apparent reason, the fault may be overloading RAM.
• 🚨 Artifacts on the screen: rarely, but it is possible to appear “broken” pixels or distortions when working with graphics (for example, in games).

If 2-3 items on the list are familiar, it's time to do a diagnosis. But don't be quick to blame RAM: similar symptoms can cause CPU overheating, a faulty battery or viruses, so the first step is to rule out other causes.

⚠️ Note: On Xiaomi smartphones with virtual memory (function) RAM Expansion in MIUI) Signs of RAM deficiency may occur even in normal physical memory. → Additionally. → Memory before diagnosis.

Method 1: Integrated tools MIUI numerical

The easiest way to test RAM is to use standard tools. MIUI. They are available on all Xiaomi, Redmi and POCO without installing additional applications.

Open the Settings. → The phone. → Memory (on some versions) MIUI The path may be different: Settings → System system → Memory. You'll see here:

• 📊 Total RAM (for example, 8 GB on Xiaomi) 12T).
• 📉 Real-time memory used.
• 🔄 Average load over the last hours.

If the free memory is less than 10-15% of the total volume, then this is an excuse to optimize the background processes.

1. Click on Clear Memory (remove the app cache).
2. Go to Settings. → Annexes → Application management and sort programs by RAM consumption.
3. Close unnecessary processes manually or set a background work limit for “gluttonous” applications.

Delete the cache in the "Memory" section

Close background applications manually

Disable Auto-Run Unnecessary Programs

Reboot your phone to reset temporary data-->

Pay attention to the schedule of RAM use: if it is constantly “clogged” to the end, even without active tasks, this is a sign of memory leak.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 12 Pro)+) Memory menus may show incorrect RAM volume due to the system's backup. Compare the metrics to your model specifications on the official website.

Method 2: Using Developer Mode for Deep Diagnostics

For advanced users in MIUI There's a hidden tool called the developer mode, which allows you to get detailed information about the state of RAM, including data about free, used and cached memory.

To activate the developer mode:

1. Go to Settings. → The phone.
2. Find the MIUI version and click on it 7 times in a row (you will be notified “You became a developer!”).
3. Return to the main Settings menu and open a new section for developers.

In the developer mode, you are interested in two sections:

• 📱 Memory: shows current RAM usage by process. Here you can see which applications eat the most memory.
• 🔍 Process statistics: displays the history of RAM usage over the past hours, which helps to identify “gluttonous” background tasks.

Pay special attention to the Available parameter RAM (If it's always close to zero, that's a sign:

• 🛠️ Lack of RAM for current tasks (solution: close applications or install "lightweight" versions of programs).
• 🐛 Memory Leaks (solution: update firmware or reset settings).
• 🦠 Viral activity (solution: scan your phone with antivirus).

💡

If you see a mediaserver process in developer mode, or system_server, more consuming 500 MB of RAM -- this could indicate a firmware error. Try updating. MIUI last-minute.

Method 3: Testing RAM through ADB (power-user)

If the built-in tools don’t give the full picture, you can use Android Debug Bridge (ADB) — Android Debugging Tool, suitable for deep diagnostics and detection of hardware problems.

First, prepare:

• 💻 Computer with installed ADB-driver.
• 📱 Xiaomi smartphone with enabled debugging USB (included in the settings → For developers).
• 🔌 USB-cable (preferably original).

Follow the instructions:

1. Connect your phone to your PC and open the command line (Windows) or terminal (macOS/Linux).
2. Enter the command to check the connection: adb devices If the device is determined – go further.
3. Follow the command to output memory information: adb shell dumpsys meminfo In the answer, find the lines MemTotal (total RAM) and MemFree (free memory).
4. For detailed analysis, use: adb shell procrank This command will show how much memory each application consumes.

Pay special attention to the parameters:

• Native Heap – Leaks here are often associated with bugs in apps.
• Dalvik Heap – problems here may indicate that the Android virtual machine is not working properly.
• Unknown – if this option takes up a lot of memory, it is a sign of system errors.

⚠️ Attention: Teams ADB Requires superuser rights (root) for full access. On most Xiaomi smartphones, root can only be obtained through unlocking the bootloader, which deprives of warranties and can lead to unstable operation of the device.

Method 4: Third-party applications for RAM testing

If you work with ADB It's hard to use specialized applications from Google Play, and they offer a user-friendly interface for monitoring and testing RAM.

Top.-3 applications for diagnostics of RAM on Xiaomi:

For a basic check, it is sufficient CPU-Z DevCheck:

1. Install the app from Google Play.
2. Open the Memory section.
3. Pay attention to this: 📌 Total RAM — Total volume (must match the model characteristics). 📌 Used RAM — memory used (normally not to exceed 70-80% in normal operation). 📌 Free RAM — Free memory (critically, if less than 500 MB on 8 GB of RAM).

If the application shows a discrepancy between the RAM volume and the declared characteristics (for example, 6 GB instead of 8 GB), this can mean:

• 🔧 Hardware defect (one of the memory chips is damaged).
• 🤖 Firmware restriction (on some Redmi models, part of the RAM is reserved for the system).
• 📉 Viral activity (some malware “hide” part of memory).

💡

If the app shows that the RAM volume is less than the manufacturer claimed, first check the specifications of your model on the official Xiaomi website.

Method 5: Performance testing (benchmarks)

You can indirectly measure RAM status using benchmarks, which are performance tests that load memory and processor to identify hidden problems.

The best benchmarks for Xiaomi:

• 🏆 AnTuTu Benchmark – tests RAM in the Memory section (estimates read/write speed).
• 📊 Geekbench 6 – Tests multithreaded performance, where RAM plays a key role.
• 🎮 3DMark — It loads graphics and memory, is useful for gamers.

How to interpret the results:

• If scores in memory tests (Memory Score in AnTuTu) are lower by 20-30% compared to the average performance of your model - this is a sign of problems with RAM.
• If during the test the phone overheats or turns off, there may be defects in memory or processor.
• If the results are unstable (strong jumps between launches) – this may indicate hardware errors.

Example: Xiaomi 13 Pro with LPDDR5X RAM is a normal memory score in AnTuTu, about 150,000 to 180,000. If your smartphone is 100,000 to 120,000, that's a cause for concern.

⚠️ Attention: Benchmarks are very loading on the device. Before testing: Charge the phone at least 50%. Close all background apps. Make sure the phone doesn't overheat (processor temperature should be below 40).°C).

What to do if you find problems with RAM

If the diagnosis revealed malfunctions, act on the algorithm:

1. Programming errors: 🔄 Update the firmware to the latest version MIUI. 🧹 Clear the cache through Settings → Memory. 🛠️ Reset the settings to factory (don’t forget to make a backup!).
2. Memory leaks: 📱 Remove suspicious applications (especially those running from unknown sources). 🔍 Check your phone with an antivirus (such as Dr.Web or Malwarebytes). 🔧 Turn off auto-run of unnecessary programs in Settings → Permits → Auto-start.

Hardware defects

• 🔧 Contact the Xiaomi service center (if the phone is guaranteed).
• 💰 If the warranty is over, estimate the cost of repair (replacing RAM chips is often unprofitable).

On Xiaomi soldered memory models (most modern smartphones), it is impossible to replace RAM - you will need to replace the motherboard. 4X) The memory may have been removable, but it is rare today.

If the problem is in virtual memory (function) RAM Expansion in MIUI), try:

• Turn it off in Settings. → Additionally. → Memory.
• Reduce the amount of virtual memory (if available).
• Use a class memory card A2 Extension (if supported).

💡

On Xiaomi smartphones with MediaTek processors (such as the Redmi Note 12), RAM problems are more often associated with firmware than with hardware. Before contacting the service, try reflashing the device via Fastboot.
