How to see the amount of memory on Xiaomi: RAM and ROM in 30 seconds

Why you should know the amount of memory on Xiaomi

RAM and embedded memory are key characteristics of a smartphone that directly affect its performance. On Xiaomi, Redmi and POCO, these parameters determine how many apps can be kept open at the same time, how many photos to save, and how fast the system will work. For example, the Xiaomi 13 Pro with 12 GB of RAM will multitask better than the Redmi Note 10 with 4 GB, even with the same processor.

But how do you know how much memory is actually available to a user? Manufacturers often say "up to 128 GB," but after installing a MIUI, there is 10-15% less free space due to preinstalled applications and system files. In this article, 5 proven ways to test memory on any Xiaomi device, including hidden methods for advanced users.

Important: Memory data may vary depending on the version MIUI (global, Chinese, EU-firmware) and smartphone models, such as POCO F5 s MIUI 14 Way to Memory Settings Different from Xiaomi Mi 11 MIUI 12.5 We have taken these nuances into account and have given universal instructions.

Method 1: Using standard MIUI settings

The easiest method is to use the built-in tools of the system. It is suitable for all models, including the Xiaomi 12T, Redmi Note 12 and POCO X5, regardless of the firmware version.

1. Open the Settings app (the gear icon on the home screen).
2. Scroll down and select About Phone (on some models – About Device).
3. Slip on Phone Characteristics or Memory (depending on MIUI version).
4. In the Storage block you will see the total volume of ROM, and in the RAM block you will see RAM data.

The screen will display information in the format:

• 📱 Built-in memory: 128GB (112GB available)
• 🧠 RAM: 8 GB (used 3.2 GB)
• 🔋 System memory: 16 GB (busy) MIUI)

⚠️ Note: Some models (e.g. Xiaomi Mi) 10T Lite) there may be no Memory tab in the About Phone section, in which case use Method 2 or Method 3.

Method 2: through the "Storage and RAM" menu

MIUI offers a separate memory management menu that not only allows you to view the volume, but also optimizes it, which works on all devices with MIUI 11 and later, including the Redmi K50 and POCO M5.

Instructions:

1. Go to Settings. → Warehouse (or Memory).
2. At the top of the screen you will see a diagram with memory distribution: 🟢 Green segment - free space 🔵 Blue - occupied by apps 🟡 Yellow - cache and temporary files 🔴 Red - system files

About the phone → RAM

💡 Useful tip: If you see a Cleanup item in the Warehouse section, tap it - the system will automatically find unnecessary files (cache, duplicates, empty folders) and prompt them to delete. 2-5 GB space.

Method 3: through the Engineering Menu (for advanced)

If standard methods don’t work (for example, on custom firmware or older models like the Xiaomi Mi A2), you can use an engineering menu, which requires caution, since improper actions can disrupt the system.

How to open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. Select Phone Information (or Usage statistics on global firmware).
4. Scroll down to the Memory block - detailed information about RAM and ROM is displayed here.
5. DevCheck 📌 Convenient interface with visualization of memory use. 📌 Shows the space occupied by system applications (for example, com.miui.gallery).

Example of data from AIDA64 for Xiaomi 12 Pro:

Memory:




- Total RAM: 8.0 GB (LPDDR5)




- Available: 3.2 GB




- Used by apps: 2.1 GB




- Used by system: 1.8 GB




- Cached: 0.9 GB





Storage:




- Total: 256 GB (UFS 3.1)




- Free: 189 GB




- System: 22 GB




- Apps: 35 GB




- Media: 10 GB

💡 Useful tip: DevCheck has a Storage Analyzer feature that shows which folders take up the most space.This helps find and delete unnecessary files (such as old backups). MIUI Backup).

Method 5: through ADB (for developers)

If you are familiar with Android Debug Bridge (ADB), you can get your memory data directly from the system, a method that is suitable for diagnosing problems or when other methods are not available (for example, on a broken screen).

Instructions:

1. Install ADB Tools on your PC.
2. Turn on USB Debugging on your smartphone: Settings → About Phone → MIUI version (tap 7 times to activate Developer Mode). Then: Settings → Additional → Developers → Debugging on USB.
3. Connect Xiaomi to your PC and execute the commands:

# Viewing information about RAM


adb shell cat /proc/meminfo




Viewing ROM information



adb shell df -h




Detailed analysis of memory usage (requires root)



adb shell dumpsys meminfo

Example of output of the command cat /proc/meminfo for Redmi Note 10 Pro:

MemTotal:        6044428 kB  (≈6 GB)




MemFree:         1832456 kB  (≈1.8 GB)




Buffers:          210348 kB




Cached:          1456780 kB




SwapCached:            0 kB

⚠️ Note: Dumpsys and root commands can cause system failure if used incorrectly. ADB without understanding the consequences!

💡

ADB-commands give the most accurate information about memory, but require technical skills. 1-3.

Frequent memory problems on Xiaomi and their solutions

Xiaomi users often face two types of problems:

1. The lack of RAM - the phone slows down, the applications close themselves.
2. ROM overflow – it is impossible to install updates or take a photo.
