Xiaomi’s current smartphones have impressive specs, but even they are not immune to internal memory overflows. One of the biggest free-space eaters is WhatsApp, which accumulates gigabytes of photos, videos and voice messages. Owners of MIUI or HyperOS-enclosed devices often face a situation where standard methods of deleting correspondence do not produce the desired result, and the space remains occupied.
The problem is the complex structure of the files created by the application. Simply deleting chats does not always erase media from the device’s memory, leaving “digital debris” that slows down the system. To effectively clean up, you need to use a comprehensive approach, combining built-in tools of the messenger and the system functions of Android.
In this article, we will discuss proven methods that will help free up space: you will learn where hidden folders hide, how to set up automatic cleaning and which files can be deleted without fear of losing important data. Proper storage management will extend the life of your Xiaomi and speed up its operation.
Analysis of the occupied space through WhatsApp settings
Before you start taking any drastic measures, you need to assess the scale of the problem. WhatsApp itself has a built-in tool that allows you to analyze in detail what exactly is taking up memory. Go to the menu, select Settings → Data and Storage → Storage Management.
Here you'll see a list of chats sorted by space, and note: it often turns out that the most important thing is not personal correspondence, but groups with active media sharing, and the system will suggest removing files larger than 5 MB or selecting media from specific dialogues.
Use selective cleaning. By clicking on a particular chat, you access a gallery of all files sent and received, which allows you to delete heavy videos while preserving text messages and important documents.
It is important to understand that deleting files through this interface is safe for a message database, but it does not always clear the cache of the preview, so it is better to use this method as a primary, regular procedure, rather than as the only solution to the problem.
Manual cleaning of system folders through the file manager
The most effective way to free up space is to manually delete files through Explorer. On Xiaomi smartphones, the best way to use the standard Explorer app or a third-party file manager with permission to access system folders. The path to WhatsApp data changed with the release of new versions of Android.
On the modern versions of Android (11 and above), the messenger files have moved to the system directory. You need to go along the way: Internal memory → Android → media → com.whatsapp → WhatsApp. Here are the Media and Databases folders.
- 📁 WhatsApp Images: All photos received and sent are stored here, including statuses.
- 🎥 WhatsApp Video: the heaviest folder containing video recordings of different quality.
- 🎙️ WhatsApp Audio: a folder with voice messages and music files sent as audio.
⚠️ Note: When manually cleaning the Databases folder, you will delete local backups, which means that you can only recover your correspondence from the last copy in Google Drive if it was made.
And you also have to look at the Sent folder inside the media directories, which stores copies of all the files you've ever submitted, and if you've deleted the original from the gallery, a copy of it can still be sitting here, taking up space.
☑️ Checklist for manual cleaning
Using Xiaomi's built-in cleaner
The MIUI shell and the new HyperOS have a powerful built-in tool to optimize the system. The Security app can find junk on WhatsApp that is not visible to the user when you normally browse. Launch the application and select "Clean up".
The system will scan the device and suggest that you delete the junk files. Be careful: sometimes the algorithm will flag as garbage the cache of images that you need to quickly load the gallery.
The Deep Clean section often hides large files that WhatsApp uploaded but you didn't even open them. These can be automatically uploaded videos from channels or group chats. Xiaomi's standard cleaner lets you sort them by size and date.
Why does Xiaomi cleaner not see all files?
Remember that the built-in cleaner works in conjunction with Xiaomi cloud services. If you have sync enabled, check if deleted files are duplicated in the cloud, taking up space there for which you may have to pay.
Automatic download and privacy settings
The best way to combat memory overflow is prevention. WhatsApp allows you to flexibly adjust the behavior of the application when you receive new content. Go to Settings → Chats and turn off Media Visibility.
If this item is active, all images and videos received automatically enter the phone gallery and sync to the cloud (if enabled).
It is critical to set up autoload media. Under Data and Storage → Media Autoboot, select the option “Only via Wi-Fi” or completely disable it for all types of networks, this will prevent heavy videos from being unobtrusively downloaded in the background.
| Setup parameter | Recommended value | Impact on memory |
|---|---|---|
| Autoloading photo | No/Only Wi-Fi | High. |
| Autoload video | No. | Critical |
| Backup | Only through Wi-Fi. | Average. |
| Quality of uploaded photos | Auto (or compressed) | Low. |
Also, limit status visibility, and you can hide your statuses from unnecessary contacts in your privacy settings, which indirectly affects the amount of preview cache you store.
Delete hidden files and cache previews
Even after deleting all visible files, hidden data remains in the system. WhatsApp creates thumbnails (previews) for each image and video so that they can be displayed faster in the chat list. These files are stored in the.thumbnails folder or similar hidden directories.
To get to them, Xiaomi Explorer needs to enable the display of hidden files. This is usually done through the Explorer settings menu (three dots or gears). Android/media/com.whatsapp/WhatsApp/Media/.Statuses.
Pay special attention to the Private folder inside the WhatsApp structure, which can store files that have been hidden by the user or moved to the archive, but are physically left on the disk, and their removal is safe if you are sure that they are no longer necessary.
💡
Use the Clear Data feature in your Android app settings only as a last resort, and this will delete all correspondence without the possibility of recovery if there is no backup in Google Drive.
Regularly cleaning the preview cache can free up 500 MB to several gigabytes of space, especially for users who are in dozens of groups and receive hundreds of images daily.
Transfer of media files to external media
If your Xiaomi’s internal memory is limited (e.g. 64GB or 128GB), the logical solution is to transfer the archives to a microSD card. SD-You can manually move media files.
Create a folder on the memory card, for example, WhatsApp_Archive. Move old videos and photos from WhatsApp Video and WhatsApp Images folders to the file manager. After moving, delete the originals from internal memory.
To access the displaced files in the future, you'll have to return them to internal memory or view them directly through the Explorer, which is inconvenient for operational work, but ideal for long-term archival storage.
⚠️ Note: Do not move the system files of the database (files with the extension.db or.db.crypt) to the memory card manually.This will damage the database and lose the entire history of correspondence.
Some Xiaomi models allow you to use a memory card as part of internal memory (Adoptable Storage feature).If your phone supports this option, this is the best way to expand the space for applications and their data without complex manipulation.
💡
Comprehensive cleaning involves not only deleting files, but also setting up autoboots, which prevents memory from clogging again in the future.
