How to find out the amount of memory on the smartphone Xiaomi Redmi: 5 ways for any model

Xiaomi Redmi smartphone owners often face the need to check the memory capacity of the device, whether it is built-in memory (ROM), RAM (RAM) or free space for installing applications, this information is critical when buying a used phone, before updating the firmware or when cleaning the device from unnecessary files, but not all users know exactly where this data is hidden in MIUI, especially if the interface is updated or the smartphone model was released long ago.

In this article, we’ll look at 5 proven ways to view memory on Redmi, from standard settings to hidden menus of engineering mode. You’ll learn how to distinguish real memory from what the system shows (taking into account service files), and how to check the read/write speed of the drive. The instructions are relevant for all models of the series, from Redmi Note 10 to Redmi 12, including budget and flagship options.

1. Standard method: via the "Settings" of the phone

The easiest method is to use the built-in MIUI tools, which are suitable for all shell versions (from MIUI 12 to MIUI 14) and do not require third-party applications to be installed.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the About Phone section (in older versions – About the device).
3. Slip on Characteristics or Memory (depending on the model).
4. You'll see here: 📱 Total internal memory (for example, 128 GB). 📊 Occupied/free space (with visual scale). 🔄 RAM volume (RAM) (For example, 6 GB or 8 GB).

⚠️ Note: In some firmware (especially on Redmi) 9A/9C) Memory may not be in About phone, but directly in the main Settings menu. If you do not find it, search by settings (the magnifying glass icon at the top of the screen).

The displayed memory volume is the same as the declared manufacturer?|Are there warnings about space shortages?|Is the speed of the storage device shown (UFS/eMMC)?|Is the type of RAM specified (LPDDR4X, LPDDR5 etc.)-->

This method shows the "user" amount of memory — that is, taking into account the deduction for system files. For example, on the Redmi Note 11 with the declared 128 GB, about 112-115 GB is actually available. This is normal: some of the memory is occupied by firmware, recovery and backup partitions.

2. Through the "Storage" in settings (detailed report)

If you want to not only know the total volume, but also see what exactly takes up space (applications, cache, multimedia), use the Warehouse section, which gives advanced statistics and allows you to quickly clear unnecessary files.

Instructions:

1. Go to Settings. → Warehouse (or Memory).
2. At the top of the screen will be a graph with the distribution of memory by category: 🎵 Audio (music, podcasts). 📷 Images (photos, screenshots). 🎬 Videos (clips, films). 📁 Documents (PDF, Excel, Word). 🤖 Annexes (APK, programme). 🗑️ Other (cache, temporary files).

Slip on any category to see a detailed list of files and the possibility of deleting them.

Important: This section only displays internal memory, and if you have a microSD card installed, the volume and contents of the card are checked separately (see section 4).

💡

Click on the three dots in the upper right corner of the Storage section and select Cleanup – the system will automatically find unnecessary files (cache, duplicates, large folders) and prompt them to delete.

3. Verification through the engineering menu (for experienced users)

If standard methods do not show full information (for example, the type of UFS 2.1/eMMC 5.1) drive is not displayed, you can look at the engineering menu. This method is suitable for advanced users and requires caution - do not change the settings unless you are sure of their purpose!

How to open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. Select Phone Information (or Hardware Info)
4. Scroll down to the Storage section – here will be detailed memory information: 🔧 Total RAM — full-time memory. 💾 Internal Storage – Type and volume of built-in storage. ⚡ Storage Type — UFS eMMC (affects the speed of work).

⚠️ Note: On some models (Redmi) 8/8A) The engineering menu may not display the type of drive, in which case use third-party applications (see section below). 5). Also, don’t click on other menu items (such as Battery Information or Usage Statistics) – this can cause crashes.

4. Checking the size of the microSD memory card

If your Redmi has a memory card installed, the memory card is checked separately.

How to check the memory card:

1. Open the Settings → Storage.
2. At the top of the screen, select the Memory Card tab (or SD-map).
3. The system will show: 📊 Total card size (e.g. 256 GB). 📁 Occupied and vacant place. 🔄 Read/write speed (if the card supports) UHS-I or A2).

⚠️ Note: If you use the memory card as internal storage (function) App2SD), The volume of the card will be displayed along with the main memory in the Warehouse section, but once the card is formatted for internal memory, it cannot be retrieved without data loss!

5. Third-party applications for detailed diagnostics

If the built-in MIUI tools aren't enough, you can use third-party utilities that show not only the storage capacity, but also the health of the drive, the speed, the temperature, and even the wear and tear of the cells (for UFS/eMMC).

• 🛠️ AIDA64 — It shows complete information about the hardware, including the type of memory (LPDDR4X, UFS 2.2) and its manufacturer (Samsung, Hynix, etc.).
• 📊 DevCheck – user-friendly interface with load visualization RAM storage.
• 🔍 CPU-Z — displays technical characteristics of memory, including the frequency of RAM.
• 🚀 AndroBench – tests the read/write speed of the drive (useful for comparison with other models).

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

Storage:




- Internal: 256 GB (UFS 2.2, Samsung KLUFG8RHDA-B2D1)




- RAM: 8 GB (LPDDR4X, 2133 MHz)




- SD Card: 512 GB (SanDisk Ultra, A2, UHS-I)

💡 Tip: If you buy a used Redmi, be sure to check the memory through AIDA64 Or AndroBench. Fraudsters can swap the drive for a cheaper one (for example, instead of a cheaper one). UFS 3.1 to set eMMC 5.1, which greatly reduces performance).

6. Verification through ADB (developer)

This method is suitable for those familiar with Android Debug Bridge (ADB), which allows you to get raw memory data directly from the system, including hidden partitions.

1. Install. ADB-PC drivers.
2. Turn on USB Debugging on your phone (Settings → About Phone → MIUI version – tap 7 times, then go back to Additional → For Developers).
3. Connect Redmi to your computer and execute in the command line: adb shell df -h This command will show all memory partitions indicating their size and occupied space.
4. To check RAM, use: adb shell cat /proc/meminfo

Example of output of the command df -h:

Filesystem Size Used Avail Use% Mounted on




/dev/block/mmcblk0p53




112G 45G 67G 41% /data




/dev/block/mmcblk0p54




2.0G 1.1G 900M 55% /system

⚠️ Note: Do not modify or format sections through ADB, If you don't understand their purpose, an error can lead to a blink (completely inoperable) of the device.

💡

ADB-commands give the most accurate information about memory, but require technical knowledge. Use this method only if the standard methods do not work or if you need data for diagnosis.

Frequent problems and their solutions

Sometimes users find that the memory capacity on Redmi is not displayed correctly.

• 🔄 Memory is eaten by no one knows what: Reason: app cache, hidden files or viruses. Solution: use Settings → Warehouse → Cleaning or Files by Google app to find garbage.
• ⚠️ Memory is smaller than stated: This is normal: part of the memory is taken by firmware (about 5-10 GB). For example, on the Redmi Note 11 Pro with 128 GB available ~118 GB If the difference is greater than 15 GB – it is possible that the seller installed custom firmware.
• 🛑 Phone does not see memory card: Check: Card format (should be) FAT32 Integrity of contacts in the slot (blow the slot with compressed air). Settings in Settings → Warehouse → Settings SD-map.
• 🐢 Phone slows down when memory is full: Leave at least 10-15% free space for stable operation. Use Lite versions of applications (for example, Facebook Lite) or transfer files to a memory card.
