Modern Xiaomi and Redmi smartphones have impressive specs, but even 128 or 256 gigabytes of internal memory can suddenly run out. Users often face a situation where the device starts to run slower, applications fly out, and the system insists on freeing up space, due to the accumulation of temporary files, error logs and inflated cache of messengers.
The Android operating system in the shell of MIUI or HyperOS is designed to βovergrowβ unnecessary data. Standard notifications about the lack of space is not just an annoyance, but a signal that the system does not have enough resources for normal swap operations. If you ignore these warnings, the smartphone may stop taking calls or taking photos.
In this article, we will look at proven cleaning methods that will help to return the device to its former speed. We will not rely on dubious applications-cliners, but use built-in tools and proven system commands. Proper cleaning will extend the life of the gadget without having to reset to factory settings.
Analysis of the storage and identification of site eaters
Before you delete files at random, you need to understand what the space is. Xiaomi owners have access to a powerful built-in analyzer that is hidden in the depth of settings. It shows a detailed breakdown by category: applications, images, videos and system files. Often it turns out that the lion's share is not your photos at all, but messenger data.
The most voracious are Telegram, WhatsApp, and Viber, which store every image and video you see in your deviceβs memory, creating duplicates, and without regular cleaning, folders of these services can grow to tens of gigabytes, stealthily eating up all the free space.
For a detailed study, use the built-in Security app. Go to Cleanup and wait for the scan to finish. The system will suggest removing the obvious debris, but for a deep analysis, go to Settings β Memory. Here you will see a visualization of occupied space.

Messengers can take up to 40% of the smartphoneβs memory if you donβt set up automatic cleaning of media files in their internal settings.
Cleaning the cache and temporary files of the system
Cache is temporary data that speeds up applications but becomes redundant over time. In MIUI, the standard utility is responsible for this, but it doesn't always delete everything. For deeper cleaning, you can use an extended menu called through certain actions, or just use the developer menu to reset the cache of specific services.
Donβt be afraid to delete the cache of system applications like the Google Play Store or Downloads. This wonβt delete your personal data, accounts or contacts. Youβll just reset temporary logs and update packs that have already been installed or lost their relevance. This is a secure procedure that is useful to do once a month.
- ποΈ Open Settings and find the App item.
- π Select All Apps and sort the list by memory size.
- βοΈ Click on the most voluminous application and select Clean β Clear the cache.
- π Repeat the procedure for top-5 most severe programs.
β οΈ Warning: Do not confuse the Clear Cache button with the Clear Everything button (or Reset) and the second option will remove your correspondence, logins and settings within the app!
Also worth paying attention to is the Download folder, where browsers and file managers often save installations. APK-files that have already been installed but forgotten by the user, and their deletion is completely secure and can instantly free up several gigabytes of data.

Working with Android and DCIM folders
The DCIM directory is the primary repository of your photos and videos, and if you're actively shooting in high resolution, this folder grows rapidly, but it often hides deleted images, and there's a Recycle Bin in MIUI that stores deleted files for 30 days, taking up space, and you have to go to the Deleted album and clean it up.
The Android folder on the internal drive contains application data, and inside it is a data subfolder that stores the cached files of games and programs, and manually touching files here is dangerous, because it can lead to resetting of game progress or loss of offline maps in the navigators, and it is better to use a file manager with the function of analyzing duplicates.
Hidden folders in Android
To find duplicates and similar images, use the built-in gallery tool or Google Files app, which can find blurry images, screenshots and identical photos, and removing that visual noise is the fastest way to get space.
- πΈ Come to the gallery. β tab.
- ποΈ Find the album Deleted and click Clean.
- π In the Files app, select the Analysis section.
- π Delete large files and duplicates offered by the system.
Use of Extended Developer Settings
For power users, Xiaomi provides access to hidden menus where you can manage memory more aggressively. Enable the developer mode allows you to see processes that are hidden from the average user. Here you can force the services that eat up RAM and create many temporary files.
To activate the mode, you need to click 7 times on the build number in the About Phone menu. After that, a new option will appear in the settings menu Additional β For developers. Here we are interested in the section related to background processes and limits.
adb shell pm trim-databasesThis command is executed through ADB (Android Debug Bridge, which allows you to compress the system's databases by removing the free space inside database files that is not freed up by standard methods. 1-2 GB in old devices.
| Function | Location on the menu | The effect |
|---|---|---|
| Process limit | For developers β Applications | Limits the number of background applications |
| Not to keep up the action | For developers β Applications | Removes activity immediately after exit (test) |
| USB debugging | For developers | Needed to connect to PC and ADB |
| Process statistics | Settings β Memory | Shows the RAM consumption in real time |
| Resetting preferences | For developers | Resets the settings of all applications |
β οΈ Attention: Changing the settings in the Developer Menu can lead to unstable system operation. Do not turn on options that you do not know the purpose of, especially those related to animation and scaling the interface.
Delete system updates and residual files
After updating the MIUI or HyperOS firmware, the device is left with an installation package, which usually weighs between 2 and 4 GB. The system often does not remove it automatically, believing that it may be needed to roll back the version or re-install it, and in everyday use this file is useless.
You can find this file in the root directory or in the folder. downloaded_rom. If you've been successfully upgraded and your phone has been stable for a few days, you can delete this archive. MIUI β debug_log, where debugging logs can accumulate if debugging was previously included.
π‘
Use the Explorer app and search for *.apk. Often, different folders store older versions of app installers that weigh a lot, but are no longer needed.
Another source of garbage is folders from remote applications, and when you delete a game or program through a standard interface, some files may remain in memory. Android/data and Android/obb The presence of folders with the names of remote games will help you find a few more gigabytes.
Memory Map and Cloud Storage as a Solution
If internal memory is critically small, consider extending. Many Redmi and budget Xiaomi models have a microSD slot. Transferring photos, videos and music to a memory card is the best solution to free up the system partition. You can't transfer system files to the map, but media files will take their rightful place there.
The alternative is cloud storage, Google Photos allows you to store your images in the cloud, removing their local copy, and the app's settings have a "Free Space" feature that automatically finds and deletes photos that have already been stored in the cloud, which is safe and convenient.
- πΎ Buy a speed class memory card at least Class 10 or U3.
- βοΈ Set up sync Google Photos over Wi-Fi.
- π Transfer heavy video files to an external drive or PC.
- βοΈ In the camera settings, select the save on SD-card if the model supports the).
Using cloud services requires a stable internet, but gives you flexibility. You can access your files from any device without downloading your phoneβs memory. For users of the Xiaomi ecosystem, Mi Cloud is also available, which is integrated deeper into the system than standard Google solutions.
