Owners of budget smartphones often face a sudden shortage of space, and Xiaomi Redmi 9A is no exception. Android, especially in the shell of MIUI, tends to gradually fill hidden sections that the user does not see in the standard gallery or file manager. Most often, the alarm is sounded when the notification of a lack of memory appears at the most inopportune moment, blocking the ability to take a photo or install the desired update of the application.
The Other category in the device's storage is not a system bug, but a special section that adds up temporary files, app cache, remnants of deleted programs, and system logs. Unlike photos or music, this data is not clearly linked to a specific type of content, so the operating system groups them into one mass, and understanding the nature of these files is the first step to managing the space correctly on your Redmi 9A.
Many users mistakenly believe that cleaning this category will lead to loss of personal data, but in most cases it is technical garbage. The right approach to maintaining a smartphone allows you to return gigabytes of free space without risking important information. Let’s figure out what exactly this volume is made of and what cleaning methods will be most effective for your model.
What is the “Other” section of MIUI
The bulk of the data in the Other category on Xiaomi devices is the cache of installed applications. Social networks, messengers like Telegram and WhatsApp, as well as browsers store a huge number of temporary files to speed up work. Cache images, video thumbnails and temporary copies of documents can take up to 70% of the volume of this section if they are not cleaned for months.
The second important component is system logs and error reports. Android constantly records information about its operation so that in the event of a failure, you can analyze the cause. On low-cost models with little internal memory, such as the Redmi 9A, these logs can grow to several gigabytes if the automatic cleanup does not work correctly.
- 📱 Messenger cache: saved stickers, contact avatars and video previews.
- 🌐 Browser residues: cookies, download history and temporary web page files.
- 🔄 Fragments of updates: installation packages APK, Remaining after installing new versions of the program.
Also, this section often includes files that the system cannot uniquely identify, such as documents in non-standard formats, archives or data from remote games. The “Other” partition on Redmi 9A is often inflated due to the peculiarities of the EMMC file system, which does not always correctly mark deleted blocks as free, which leads to the fact that formally the space is occupied, although the physical files may no longer be needed.
Memory analysis through engineering menu and settings
Before you start taking drastic measures, you need to conduct a detailed diagnosis. Xiaomi's standard settings menu provides basic information, but for in-depth analysis, you should use more advanced tools. Go to Settings → About Phone → Storage to see the overall picture of the data distribution.
For a more detailed look, you can use the built-in Security app, which scans the device and offers to clean up the garbage, but often skips (deep) system folders. To see the real size of the folders, including hidden ones, sometimes you need to connect to a computer or use a special utility, but Redmi 9A can be used with regular means, if you know where to look.
| Type of data | Wherever | Can I remove it? | Impact on the system |
|---|---|---|---|
| Cash app. | Settings → Applications | Yes, it's safe. | Apps will run a little longer |
| Files.thumbnail | DCIM →.thumbnails | Yeah, but they'll come back. | Gallery opening will accelerate |
| Logs of debugging | System section | Only through ADB or reset | No impact on the job |
| APK remnants | Download folder or MIUI | Yes. | Absent. |
It is important to understand the difference between user data and system files. If you see the volume of the Other skyrocketing after installing a particular application, the problem is likely to be its malfunction or overcrowded cache. In such cases, forcing a shutdown and clearing of a particular application’s data often solves the problem more effectively than a general cleanup.

Safe Ways to Clean Cache and Temporary Files
The easiest and safest way to free up space is to use a built-in cleaning tool. Open the Safety app on the home screen and click the Clean button. The system will analyze the device and suggest that you delete temporary files that do not affect the stability of the work.
Deeper cleaning requires manual intervention in the settings of applications. Go to Settings → Applications → All applications. Select "heavy" programs (social networks, browsers) and go to the Memory section. There you will see the "Clear cache" button. Importantly, do not confuse this button with "Clean everything", since the second action will delete your logins and settings inside the application.
- 🗑️ Clearing the Telegram cache: inside the application in the section "Data and memory» → «Use of memory» → «Clear the cache».
- 🌍 Chrome Cleanup: Three Dots in the Corner → History → Clear history → Select “Images and other files».
- 📂 Remove downloads: check the Download folder and remove old installers APK.
⚠️ WARNING: When cleaning messenger data, make sure you have a backup of important chats if you're not sure what you're deleting.Cache can be cleaned boldly, but App Data will reset the program to its original state.
After all the manipulations, it is recommended to restart the device, which will allow the Redmi 9A system to correctly recalculate the file system index and display the current amount of free memory, often the visual space is vacated only after restart.
☑️ Checklist for Redmi's quick cleaning 9A
Delete hidden system files and logs
If standard methods didn’t work and the Other category is still suspiciously large, it may be a backlog. On Redmi 9A, these files can be stored in hidden memory areas. Accessing them will require root rights that are not available on standard MIUI firmware, so we’ll go a safe route through clearing user logs.
One effective method is to clean the.MIUI or MIUI folder at the root of internal memory, where error reports can be stored, and check the tombstones folder (if there is access) where application crash data is stored, and removing the contents of these folders is safe, as the system will create new files if necessary.
Another source of garbage is the Android/data and Android/obb folder, which stores game and app data, and if you delete the game but you still have the folder, you can erase it, but beware: removing active application folders will lead to loss of progress in games or program settings.
💡
Use the “Free Space” feature in Google Files.This app often finds duplicates and large files that the standard Xiaomi analyzer skips.
In some cases, the growth of the "Other" section is due to an error in indexing media files. If you deleted a lot of photos or videos, but the memory is not free, try to turn off the phone, remove the phone. SD-The card (if used) and turn it back on, which will force the system to re-scan the media storage.
The specifics of working with memory on Redmi 9A
The Redmi 9A is based on the MediaTek Helio G25 processor and uses the eMMC 5.1 type of memory, which has its own features: write and read speeds are lower than modern flagships, and the mechanism of working with the file system can lead to faster fragmentation, which is why the “Other” category tends to grow faster on budget.
The MIUI operating system, being a rather heavy shell, requires a significant reserve of free memory for comfortable operation.If the space on the Redmi 9A drops below 1 GB, the system starts to run slower, and the cleaning process of the Other becomes critical to maintaining performance.
- 📉 Fragmentation: Frequent file write and deletion slows down eMMC memory.
- 🛑 System limit: when filling memory more than 90% of possible failures MIUI.
- ⚡ Cash mechanisms: Budget processors process cache more slowly, so it needs to be cleaned more often.
Users of this model are advised not to store large amounts of files on the internal drive, but rather use cloud services or an external microSD card, although it will not save the Other partition from proliferation, since it is formed in the internal storage.
⚠️ Warning: Do not attempt to delete files from system folders through root-righted file managers unless you are 100% sure of their purpose. 9A This can lead to a “bootloop” (cyclic reboot), and it will be difficult to recover a phone without a computer.
Radical measures: reset to factory settings
If neither method helped reduce the size of the Other category and it continues to take up half the memory, there is likely a serious error in the file system, in which case the only effective solution is a complete factory reset, which will return the phone to a store-like state.
Before you start, make sure to back up all your important data. Reset will delete everything: contacts, photos, apps and settings. Go to Settings → About Phone → Reset → Erase all the data. The process will take a few minutes, after which the phone will restart.
Settings → About the phone → Reset settings → Erase all dataOnce reset, the Other section will be minimal, taking up only the necessary system files, the best way to get rid of deep file system errors that cannot be fixed software, and regular maintenance of the phone will help avoid having to resort to this measure in the future.
💡
Full reset is the only guaranteed way to clean up Other if it has grown due to file system errors or firmware bugs.
Preventing memory overflow in the future
To keep the space shortage problem on the Redmi 9A from returning in a month, you need to develop a habit of regular maintenance: Don't wait for the phone to report a critical space shortage, run a standard cleaning once a week and check the "heavy" apps.
Set up automatic cache cleaning in messengers, for example, Telegram can set a limit on the shelf life of media files (for example, 3 days or 1 week), which will prevent the accumulation of gigabytes of useless images and videos in the memory of your device.
- 📅 Weekly routine: cleaning the cache of browsers and social networks on weekends.
- ☁️ Cloud Photos: Enable Google Photos Sync with Free Place».
- 🚫 Download control: delete installation files immediately after installing programs.
By following these simple rules, you will extend the life of your Redmi 9A and ensure its stable operation.Memory is a limited resource, and competent management of it is the key to comfortable use of a smartphone based on Android.
