How to find out the amount of memory on Xiaomi Redmi Note 8: all ways

Xiaomi Redmi Note 8 remains one of the most popular smartphones in the budget segment even years after its release. However, over time, many users face a lack of memory — applications slow down, photos are not saved, and the system gives notifications about overflow storage. If you are not sure how much memory was originally in your device or how much space is left, this article will help to understand.

We’ve compiled all the current ways to check, from standard settings to hidden engineering menus, and you’ll also learn how different the memory in different versions of the Redmi Note 8 (3/32 GB, 4/64 GB, 4/128 GB) and what to do if the system shows incorrect data. Instructions are suitable for all firmware: MIUI 12-14, including global and Chinese versions.

1. Memory check through standard Android settings

The easiest way is to use the built-in MIUI tools, which require no additional apps and works even on a “clean” smartphone without superuser rights.

Open the Settings → About the phone menu. Here you will see basic information about the device, including the total amount of RAM and ROM. However, for a detailed analysis of the free space, go to Settings → Memory (in some versions of MIUI, the path may look like Settings → Storage).

• 📱 Internal memory – shared and free space;
• 📁 The amount of the system that is occupied MIUI and pre-installed annexes;
• 🖼️ Multimedia – photos, videos, audio files;
• 📦 Applications and data – user programs and their cache.

Note that if you have a microSD card installed, the memory capacity will be displayed separately. Redmi Note 8 supports cards up to 512 GB, but the speed is lower than with the built-in memory eMMC 5.1.

💡

If the Memory section displays less space than it should be according to the characteristics of the model (for example, 55 GB instead of 64 GB), this is normal - firmware and service files take up part of the memory.

2.Use of the application "Security" (Security)

Xiaomi’s proprietary Security app not only protects the device from viruses, but also provides advanced memory information, a method that is useful if you need to quickly clear your cache or delete unnecessary files.

Instructions:

1. Open the Security app (the shield icon).
2. Go to the Optimization or Cleanup tab (depending on the MIUI version).
3. Click on the Memory or Storage block.
4. Wait until the scan is completed, the system will show a detailed report on file categories (including junk data).

The advantage of this method is that one tap can clear the cache of all applications, but be careful: deleting the cache of some programs (for example, messengers) can lead to the loss of unsaved data.

3. Engineering menu: hidden memory data

For advanced users who need technical memory information (e.g. chip type, read/write speed), an engineering menu is suitable. USSD-Code and caution – do not change settings unless you are sure of their purpose!

How to open it:

1. Open the Phone app.
2. Enter the combination: ##4636##
3. In the menu that appears, select Phone Information.
4. Scroll down to the Memory block, where RAM and internal memory data, including real-time free space, are displayed.

The engineering menu also includes swap and dalvik-cache, which are useful for diagnosing the brakes, but changing them without special knowledge can be dangerous, causing MIUI to fail.

4. Third-party applications for memory analysis

If standard MIUI tools aren’t enough, you can use third-party utilities that offer more visual representation of data and additional features, such as searching for duplicates or large files.

Warning: some annexes (e.g, SD Maids require root rights to work properly. On Redmi Note 8, rooting can lead to loss of warranty and problems with the service. OTA-Use them only if you understand the risks!

5. Check through ADB (for advanced users)

If you want the most accurate memory data (for example, to diagnose malfunctions), you can use Android Debug Bridge (ADB), which is suitable for developers or those who repair smartphones.

Instructions:

1. Install ADB Tools on your PC.
2. Enable USB Debugging on your smartphone: Settings → About Phone → MIUI version (click 7 times to activate Developer Mode), then Settings → Additional → Developers → Debugging over USB.
3. Connect the Redmi Note 8 to your computer and execute in the command line: adb shell df -h This command will show the breakdown of memory by partition (system, data, cache, etc.).

To check the RAM, use:

adb shell dumpsys meminfo

This command will display a detailed report on RAM usage, including data on each running process.

⚠️ Attention: Use ADB Incorrect commands (e.g. adb shell rm) -rf /data) If you're not sure what you're doing, you better use other methods.

6. Comparison with other Xiaomi models: what has changed?

Redmi Note 8 was released in three main memory configurations: 3/32 GB, 4/64 GB and 4/128 GB. For comparison, in newer models (for example, Redmi Note 11) used chips UFS 2.2 instead of eMMC 5.1, which increases the read / write speed almost 2 times.

If you are planning an upgrade, note the following differences:

• 📈 Redmi Note 8 Pro has a LPDDR4X RAM (against LPDDR4 In the standard version, which improves multitasking.
• 🔄 Redmi Note 9 – supports microSD up to 1 TB (vs. 512 GB in Note 8).
• ⚡ POCO X3 NFC — fitted UFS 2.1 and has a 20% faster memory speed.

If your Redmi Note 8 is getting a lot of slowdown, maybe the problem isn't memory capacity, it's type. For example, cheap eMMC models get degraded over time, and the write speed drops after multiple write cycles, and then just replacing the memory chip in the service center will help.

💡

If your Redmi Note 8 has a 3/32GB configuration, consider upgrading – modern apps (like Genshin Impact or Call of Duty Mobile) require a minimum of 4GB of RAM for comfortable play.

7. Frequent problems and their solutions

Redmi Note 8 users often face the following memory-related problems:

• 🔄 "Memory is full, but there are few files – check the folder /sdcard/Android/obb, where the game caches are stored (may take up to) 10–15 GB).
• ❌ No memory card visible – restart your device or format microSD in FAT32 (PC).
• 🐢 The smartphone slows down when filling memory by 80% - this is a feature of eMMC. Solution: leave at least 10-15% of free space.

If the system shows the wrong amount of memory (for example, 28 GB instead of 32 GB), this may be due to:

1. Fake storage (found in unofficial remarks).
2. Error of partition markup after firmware.
3. Hardware damage to the memory chip (for example, after a fall).

⚠️ Note: If after resetting settings (Settings) → Additionally. → Recovery and reset) memory capacity has not recovered, this is a sign of hardware malfunction.
