How to find out the memory status on Xiaomi: a complete guide with instructions

Slowing down a smartphone, sudden reboots or reports of memory shortages are familiar problems? On Xiaomi devices (including Redmi, POCO and Black Shark), memory status affects not only performance but also the life of the gadget. Unlike iPhones or smartphones on pure Android, MIUI firmware has unique diagnostic tools that often go unnoticed.

In this article, you’ll find 5 proven ways to test memory on Xiaomi – from standard features to hidden engineering menus. We will discuss how to distinguish between physical wear and tear of the drive from software freezes, what indicators are considered critical, and what to do if the system shows incorrect data.+ budgetary POCO M6.

1. Standard MIUI tools: where to look at memory status

MIUI provides basic memory information right in the settings to find it:

  1. Open the Settings. β†’ The phone.
  2. Slip on the item Memory (or Storage in new versions).
  3. The system will show a diagram with the distribution of memory by category: Applications, Images, Video, etc.

But there's a catch: MIUI doesn't show the actual state of the drive (e.g., the number of overwrites or read errors), but it's hidden in the engineering menu, but you can quickly make room in this section:

  • 🧹 Clean up garbage: Clean up button removes cache and temporary files.
  • πŸ“ Large files: the system automatically finds videos and documents over 50 MB.
  • πŸ” Recommendations: MIUI Remove unused applications or transfer files to the cloud.

⚠️ Note: If the Memory section displays another more than 10 GB, it is a sign of fragmentation or failure of the file system.

πŸ“Š How often do you check your memory status on your smartphone?
Once a week.
Only when it's slowing down.
Never checked.
I use third-party apps.

2. Hidden settings: engineering menu and memory tests

For deep memory diagnostics on Xiaomi, use the CIT (engineering menu) that is available on all models, but the path to it is different:

  • πŸ“± Method 1 (for new models): Enter the Phone application code ##4636##, then select Testing β†’ Memory.
  • πŸ”§ Method 2 (for older devices): Use the code ##284## for the drive test.

In the engineering menu, pay attention to the following parameters:

ParameterNormal value.What does deviation mean?
eMMC Life Time0–70%Over 80% critical wear and need replacement
Bad Blocks0Any value > 0 indicates the damaged sectors.
Read/Write SpeedComparable with the model’s passport dataA 30%+ drop in speed is a sign of wear and tear

If the engineering menu is not available (on some POCO and Black Shark), use the MTK Engineering Mode app (for MediaTek processors) or Qualcomm Test Mode (for Snapdragon), which give you access to the same tests but through a graphical interface.

On smartphones with a Snapdragon processor (for example, Xiaomi) 13T) To access hidden memory settings, you sometimes need to turn on the developer mode. MIUI in the section About the telephone

Third-party apps: what AIDA64 and DiskInfo will show

Standard MIUI tools often hide the actual state of memory.

  • πŸ“Š AIDA64: Shows the type of memory (UFS 2.1/3.1, eMMC 5.1), The storage temperature and read/write speed. β†’ Memory devices look for the Health Status option.
  • πŸ’Ύ DiskInfo: Specializes in wear analysis. Shows Total Host Writes (total volume of recorded data) and Wear Leveling Count (degree of wear and tear).
  • πŸ› οΈ DevCheck: A user-friendly interface to check all hardware components, including memory.Storage tab shows Disk Health as a percentage.

An example of the report from AIDA64 for Redmi Note 12 Pro+:

Storage Type: UFS 3.1




Health: 92% (Good)




Total Writes: 12.4 TB




Bad Sectors: 0




Read Speed: 1200 MB/s




Write Speed: 850 MB/s

⚠️ Note: If DiskInfo shows Health Status: Warning at a value below 80%, this does not always mean the imminent death of the drive. UFS 3.1 (e.g. Xiaomi 14 Ultra) has a higher safety margin than the eMMC 5.1 in budget models.

Memory type (UFS/eMMC)|Read/write speed |Health Status |Number of bad sectors |Drive temperature-->

4. ADB commands: how to get data without root

For advanced users, there is a way to check memory through ADB (Android Debug Bridge), which does not require root rights and works on all Xiaomi models:

  1. Install ADB Tools on your PC.
  2. Turn on USB debugging in the developer settings (Settings β†’ About Phone β†’ MIUI version – tap 7 times).
  3. Connect your smartphone to your PC and execute the commands:
adb shell


su -c "cat /sys/block/mmcblk0/device/life_time"

This command will return two values:

  • Life Time A is the wear and tear of the system partition.
  • Life Time B is the wear and tear of the user section.

For models with UFS (such as Xiaomi 13 Pro) use:

adb shell


su -c "cat /sys/block/sda/device/life_time"

Normal values:

  • 🟒 0–50: Memory in excellent condition.
  • 🟑 50–80: moderate wear and tear, it is worth thinking about backup.
  • πŸ”΄ 80+: Critical wear and high probability of data loss.
What if the ADB does not recognize the device?
1. Make sure that the debugging is enabled by USB and the connection is selected as "File Transfer". 2. Update the drivers ADB via Windows Device Manager (manually specify the path to the folder with the platform-tools). 3. Try another one USB-cable (original from Xiaomi) – cheap cables often don’t support data transfer. 4. Reboot your smartphone and PC, then reconnect.

5. Physical Diagnostics: When the Problem Is Not in Software

If all the tests show that the memory is fine, but the smartphone still slows down or gives out errors, the problem may be hardware.

  • πŸ”„ Cyclical reboots when trying to write files.
  • πŸ“± Logo hangings MIUI post-refresh.
  • πŸ”‹ Overheating in the lower part of the body (where the memory is located).
  • 🚫 Error "Storage space damaged" when connecting to a PC.

In such cases:

  1. Try to reflash the device via Fastboot (see instructions for your model at xiaomi.eu).
  2. If the flashing does not help, contact the service center. Xiaomi with a guarantee of up to 2 years (in Russia - up to 1 year) will replace the memory for free when confirming a factory defect.

⚠️ Attention: On devices with UFS 3.1 (e.g. Xiaomi) 12T) Physical memory damage is often disguised as software failures, and if the problem remains after the factory reset, it is a 100% hardware malfunction.

πŸ’‘

Xiaomi smartphones since 2022 (12/13/14) use UFS 3.1/4.0 memory, which is less prone to wear than eMMC in budget models. However, it is sensitive to overheating - avoid direct sunlight and games when charging.

6.Memory optimization: how to extend the life of the drive

Even if your memory is in good condition, a few simple rules will help you avoid premature wear and tear:

  • πŸ”„ Turn off automatic cache cleaning in Settings β†’ Memory. β†’ Autocleaning: Frequent cleaning reduces memory life.
  • πŸ“ Transfer heavy files (video, games) to microSD. on Xiaomi with hybrid slot use cards UHS-I class A2.
  • ⚑ Avoid charging during intense recording (e.g., updating or shooting videos in the video) 4K). This increases the heat of memory.
  • πŸ”„ Update. MIUI β€” In new versions optimized algorithms for data recording.

For eMMC models (e.g. Redmi 9A or POCO C50) it is particularly important to:

  • Do not use your phone as a flash drive (frequent PC connections).
  • Turn off background synchronization for unnecessary applications.
  • Use light firmware (for example, MIUI Lite or custom builds based on Android Go).

On devices with UFS (Xiaomi 11/12/13/14), the main threat is overheating. Monitor the temperature through the CPU Monitor app and avoid:

  • Charging games.
  • Use of covers with poor ventilation.
  • Place your phone near heat sources (e.g., on a car torpedo in summer).

FAQ: Frequent questions about memory on Xiaomi

❓ Why Xiaomi? 13T It shows that the memory is full, but I have not established anything?
This is a typical MIUI problem associated with system file caching. Try: Clear cache via Settings β†’ Memory β†’ Clean. Delete the.thumbnails folder in internal memory (it stores thumbnails of images); Disable the Mi Cloud function if it automatically syncs files; If it doesn't help, reset to factory settings (don't forget to make a backup!).
❓ Can I replace my memory with Xiaomi?
Theoretically, yes, but: On UFS models (like the Xiaomi 12S Ultra), memory is soldered to the motherboard. Replacing requires a soldering station and experience. Budget smartphones (like the Redmi A2) sometimes use a removable eMMC chip, but it is difficult to find on sale. Self-replacement is unwarranted and can lead to the loss of IMEI. We recommend contacting service centers that use the original Xiaomi chips.
❓ How to transfer applications to a memory card on Xiaomi?
Starting with MIUI 12, porting applications to microSD is limited. bypass: Insert a memory card (SanDisk recommended) A2 Samsung EVO Format it as internal memory in the storage settings. Use App Mgr. III (requires rooting or Link2SD forced transfer. ⚠️ After formatting as internal memory, the card will not be used on other devices!
❓ Why After Updating MIUI The memory was not showing up correctly?
This is a firmware bug that occurs after an over-the-air update (OTA) Solutions: Reboot your device. Clear the cache through Settings β†’ Apps β†’ App Management β†’ Three dots β†’ Clear the cache of all applications. If it doesn't, run a clean MIUI installation through Fastboot.
❓ How to check memory Xiaomi without installing applications?
Use the built-in tools: Engineering menu (codes ##4636## or ##284##). ADB-commands (described in section 4) Test through Settings β†’ The phone. β†’ All specifications β†’ Memory (only shows fullness, not status). For accurate diagnostics without apps, connect your smartphone to your PC and use CrystalDiskInfo (requires enabled debugging on your PC). USB).
