Xiaomi Redmi smartphones are known for their price-performance ratio, but even the most advanced models face memory shortages over time. Slowdowns, sudden reboots or the inability to install a new app are all signs that internal storage is full of unnecessary files. Unlike flagship devices, budget Redmis often come with modest 32-64 GB of memory, where every megabyte counts.
In this article, you will learn not only how to view the memory status of your Xiaomi Redmi, but also how to properly analyze occupied space, find junk files and optimize storage without losing important data. We will look at both standard MIUI tools and third-party utilities that will help you squeeze the maximum out of the available volume.
1. Standard method: Memory verification via MIUI settings
The easiest method is to use the built-in operating system tools. It is suitable for all Redmi models, from Redmi 4 (2016) to the current Redmi Note 13 (2026). MIUI, But the general logic holds.
To open the section with information about memory:
- Go to Settings (the gear icon on the home screen).
- Select About Phone (in older versions - About Device).
- Put it in the storage (or memory).
Here you'll see a graph of how to categorize memory by app, image, video, audio, cache, etc. Click on any category to see a detailed list of files, for example, in the Applications section, you can sort programs by size and remove the most voracious ones.

If you see com.android... or miui... in the list of applications, these are system services. You can't delete them, but you can clear the cache (the "Clear" button in the application card).
- ๐ Advantages of the method: does not require the installation of third-party programs, works without the Internet, shows system files.
- โ ๏ธ Disadvantages: Not always accurately detects junk files, no deep cleaning tools.
- ๐ Tip: If the graph shows โOtherโ more than 5 GB โ this is a reason for a deep check (more about this in section 4).
2. Alternative method: MIUI file manager
The integrated File Manager (file-magnifying icon) offers more flexible tools for memory analysis, allowing you not only to view occupied space, but also to immediately clear unnecessary data.
- Open the File Manager.
- In the lower menu, select Categories (or Storage Analysis in newer versions).
- Wait for the scan to be completed (it may take 10 to 30 seconds).
- Click on the category (such as โBig Filesโ or โUnused Appsโ) to see the details.
The Duplicates section is especially useful, finding repetitive photos, documents, and audio files, for example, if you backed up photos in Google Photos but didn't delete the originals, you can find and remove duplicates here, saving up to a few gigabytes.
Look for file sizes >500 MB in the section "Large files"|Check the download folder - unnecessary ones often accumulate there. APK archives|Remove the application cache in the "Cleaning" section"|View โRecently Deletedโ โ files are stored there for 30 days and take up space-->
โ ๏ธ Warning: If you see the folder MIUI Or Android at the root of the storage -- don't manually delete it, it can cause system failures.
Memory check through the engineering menu (for advanced users)
If standard methods donโt give the full picture, you can use the engineering menu, which is suitable for Redmi models based on Qualcomm processors (for example, Redmi Note 10 Pro, Redmi K50) and requires caution โ wrong actions can disrupt the device.
To open the engineering menu:
- Open the Phone app.
- Enter the combination: ##4636###.
- In the menu that appears, select Storage.
Here you will see technical data on memory including:
- ๐ฑ Internal Storage โ Free/Common Space;
- ๐๏ธ System Storage โ memory occupied by the OS (usually 8-12 GB);
- ๐ Cache - Cache size;
- ๐ Available โ Available space.
This method is useful if you suspect that the system is not displaying free space correctly, for example, if the settings show 10 GB free, and the engineering menu shows only 5 GB, this may indicate that the file system is damaged.
What if the data in the engineering menu and settings do not match?
4. Third-party applications for deep memory analysis
Built-in MIUI tools don't always show the full picture, for example, they might miss:
- ๐๏ธ Cache system applications (e.g. Google Play Services);
- ๐ฆ Residual files after deleting programs;
- ๐ Hidden folders with logs and dumps;
- ๐ฎ Game cache files (can take up to 1-2 GB per game).
For a detailed analysis, we recommend the following applications (available on Google Play):
| Annex | Features | Cons |
|---|---|---|
| Files by Google | It shows junk files, duplicates, rarely used applications, and it has a built-in cleaner. | It does not analyze MIUI system folders. |
| SD Maid | Deep scanning of cache, residual files, databases, supports cleaning on schedule. | Requires root rights for full-time work. |
| DiskUsage | Visualizes the space occupied by an interactive map, helps you find the heavy folders. | There are no built-in cleaning tools. |
| CCleaner | Clears the cache, history, temporary files, and there's a RAM optimizer. | Aggressive advertising in the free version. |
Example of working with DiskUsage:
- ๐ After scanning, you will see a pie chart where each sector is a folder or file.
- ๐ฑ๏ธ Slip through a large sector to see its contents.
- ๐๏ธ Click on the unnecessary file and select โDeleteยป.

โ ๏ธ Warning: If the application requests root access to clean system files, refuse! Incorrect use of root rights can lead to a device blink (completely inoperable.
5. How to Free Memory on Xiaomi Redmi: Practical Tips
Knowing how to look at memory is useless without optimizing it, and here are some proven ways to make room:
- ๐ธ Photos and Videos: Transfer media files to Google Photos (free to Google Photos) 15 GB) or on a memory card. Enable photo compression in the camera settings (Camera settings) โ Permission โ High (HEIF)). Remove screenshots from older 30 days (daddy) Pictures/Screenshots).
- ๐ฎ Games: Clear the cache of games through Settings โ Annexes โ [play-name] โ Warehouse โ Clear cache. Use cloud-based saves (e.g. in Genshin Impact or PUBG Remove unused games - one AAA-The game can take up 3-5 GB.
- ๐ฑ System Files: Clear the Google Play Services cache and MIUI System once a month. Remove old updates in the folder /sdcard/MIUI/backup. Turn off automatic download of updates for apps on Google Play โ Settings โ Auto-update.
๐ก
The most voracious apps on Xiaomi Redmi are Facebook (cache up to 1GB), TikTok (videocache), and WhatsApp (media in chats).
If there is critically little space (less than 1 GB), the system automatically removes the cache, which can lead to brakes.
- Move the files to the memory card (if supported).
- Remove unused applications (even system ones if you donโt need them).
- Do a cache reset via Recovery (see Section 6).
6.Diagnostics of memory problems: when to sound the alarm
Sometimes, a memory deficit is a symptom of a more serious problem, and note the following:
- ๐จ Symptom: After deleting files, the free space does not increase. Cause: Damage to the file system or wear of flash memory (typical for devices older than 3-4 years).
- ๐จ Symptom: The device freezes when copying files. Cause: Memory controller defects or chip overheating.
- ๐จ Symptom: The engineering menu shows "0B free" although there is room in the settings. Cause: Partition mounting error (solved by rebooting or resetting).
If you experience at least one of these symptoms, follow these steps:
- Reboot the device โ this will reset temporary file system errors.
- Check your memory for errors via Recovery: 1. Turn off your phone. 2. Press Volume Up + Power before the MI.3 logo appears. Select Wipe & Reset โ Wipe Cache. 4. Confirm the action and reboot.
- Test the memory with the A1 SD Bench app (read/write speed checks). If the speed is below 50 MB/s, the flash memory is worn out.
โ ๏ธ Note: if after resetting the cache through Recovery the problem did not disappear, and the memory speed fell below 30 MB / s - this is a sign of hardware wear. In this case, only replacing the motherboard will help (the cost of repair may exceed the price of the device).
