Xiaomi smartphones have long proven to be great value for money, but even flagship models eventually begin to suffer from a lack of space. MIUI or its modern version of HyperOS actively accumulate temporary files, app cache and system logs that over time take up gigabytes of precious space. When storage is overflowing, the device begins to work slower, and new photos or applications simply cease to be saved.
There are many ways to get your phone back up and free up space without having to reset completely. In this article, we’ll take a look at the full-time cleaning tools, system folders, and advanced garbage removal techniques that not everyone knows about. The right file management approach will allow your smartphone to work as new throughout its life.
Analysis of vault occupancy
Before you start taking action to delete files, you need to determine exactly what takes up the lion’s share of memory. owners of Redmi and Poco devices often mistakenly believe that space is only photos, while the main “eaters” are often messengers and cache streaming services. Standard android system does not always give a detailed picture, so it is better to use built-in shell tools.
To start your diagnosis, go to Settings → About Phone → Storage, where the system visualizes data and shows the distribution of space between applications, images, videos and system files. Notice the “Other” section, which often hides the remnants of deleted programs or temporary update files, and analyzing this structure is the first step to competent optimization.
⚠️ Warning: Do not delete files from system folders that you do not know the purpose of. This can lead to unstable interface operation. MIUI or complete inoperability of individual phone functions.
If you see that most of the apps are in use, it makes sense to re-examine the list of installed software, often forgetting about games or programs that have not been used in months, and removing such heavyweights instantly frees up a significant amount of space without losing important personal data.
Use of built-in cleaner
Each Xiaomi smartphone has a Security system app preinstalled, which includes a powerful garbage cleaner, which scans the device for temporary files, residual data after deleting apps and advertising cache, and can be run by clicking on the Cleanup icon in the app's main menu or through a widget on the desktop.
The analysis process usually takes a few seconds, after which the system will suggest removing the debris found, but don't blindly agree with everything the system offers. Carefully review the list: sometimes there are important documents or recently downloaded files that you planned to use. Cleanup should be selective and conscious.
☑️ Checking before cleaning
Special attention should be paid to the section "Big files" scanner often finds video files forgotten in the folders of downloads of browsers or instant messengers, removing such objects can free up several gigabytes in just one click, and it is recommended to regularly clean the browser cache, which has the property of growing to hundreds of megabytes when actively surfing the Internet.
Working with garbage in messengers
The most voracious apps on any Android device, including Xiaomi, are Telegram, WhatsApp, and Viber. They store every photo, video, and document you view in your phone’s memory, even if you’ve already deleted a correspondence or the file has been deleted by the sender. Without regular cleaning, these apps can take up to 10-20 GB of storage.
In Telegram, cleaning is done most efficiently through internal settings: go to Settings → Data and memory → Memory Use. Here you can set up automatic deletion of the cache, for example, after 3 days or a week, and also manually clean all accumulated garbage. This action will not remove your correspondence from the server, but will free up space on the device.
On WhatsApp, the situation is more complicated because files are stored in the file system. Go to Settings → Data and Storage → Storage Management. The app will show you a list of chats that occupy the most space and allow you to delete media files selectively. Often these chats are unnecessary cards, voice messages or duplicate photos.
Why is the messenger cache growing so fast?
Remember that once the messenger cache is cleared, when you re-open old photos, they will be downloaded from the Internet again, so it is better to do this with a stable Wi-Fi connection, so that mobile traffic is not consumed.
Cleaning up DCIM folder and screenshots
The DCIM (Digital Camera Images) folder is the standard storage for all photos and videos taken by your Xiaomi camera. Over time, thousands of images accumulate here, including failed frames, blurred photos and long videos in high resolution, which is the section most often overflows with the internal memory of the device.
Special attention should be paid to the Screenshots folder, which stores all the screenshots you take. Users often take screenshots to save important information (passwords, addresses, correspondence), but forget to delete them after use. These files can lie dead weight for years, taking up space. Regular audit of this folder is a good habit to maintain order.
For quick navigation and deletion, use the built-in Gallery app or file manager. The MIUI Gallery has a handy Albums feature, where files are sorted by type and date. You can quickly go to the Screenshots or Video album and delete the excess by mass selection. Remember to clean the Recently Deleted folder after that, since the files are stored there for another 30 days.
| Type of folder | Positioning in conductor | What can be removed | Risk of removal |
|---|---|---|---|
| Camera. | DCIM/Camera | Unnecessary photos, test videos | Loss of personal photos |
| Screenshots | DCIM/Screenshots | Old screenshots, checks | Loss of stored info |
| Downloads. | Download | APK installers, documents | Low. |
| Bluetooth | Bluetooth | Accepted files from others | Low. |
💡
Use cloud services (Google Photos, Yandex.Disk) with autoload and then delete local copies, which will free up gigabytes by leaving access to photos over the Internet.
Delete residual files and application cache
When you delete applications in the standard way through the settings menu, the phone often has tails — empty folders, configuration files, and temporary data — that may not carry a critical load, but collectively create chaos in the file system and take up space. Deep cleaning requires a file manager with extended access rights.
The built-in MIUI Explorer allows you to go to the root directory of Android/data and Android/obb. It stores game and heavy-app data. If you delete a game but the folder with its name (e.g. com.gameloft.android) is left, it can be safely removed manually. Be careful that removing the active-game folder will lead to loss of progress or the need to re-download resources.
It's also worth checking the folder. MIUI/debug_log, If it exists, some firmware versions can write debugging logs that take hundreds of megabytes to debug, unless you're a developer and you're debugging the system specifically, you don't need those files, and deleting them is safe and frees up space.
⚠️ Note: When manually cleaning your Android folder, make sure you only delete data from remote applications. Deleting the folders of Google or Xiaomi system services can cause notifications and sync failures.
For safer and more automated cleaning, you can use specialized tools like Files by Google or SD Maid, which can find orphan files left over from uninstalling programs and suggest removing them, a more reliable way than manually digging into system directories.
Hiding and Removing System Updates
One of the hidden problems with Xiaomi devices is the accumulation of system updates. When the phone downloads a MIUI or HyperOS update in the background, the firmware file (weighing 2 to 4 GB) is stored in internal memory. If you do not plan to update right now or the update is already installed, this file can be deleted.
Update files are usually in the folder. Downloaded_rom To find them, turn on the hidden files in the Explorer settings. Having a file with the.zip extension and a name that contains the firmware version indicates an update packet. Deleting it will free up a significant amount of memory.
💡
System update files are taken from 2 before 4 GB of memory: If the update is already installed or you do not plan to install it, delete the packet from the folder Downloaded_rom safely and efficiently.
Also, you should turn off automatic update downloads if you don't have enough space. Go to Settings → About Phone → MIUI version, click three dots in the corner and select "Update Options." Turn off "Update" option. This will prevent the space from suddenly disappearing at the most inopportune moment.
Expanding memory with maps and clouds
If software cleaning methods don’t work, consider physical or virtual storage expansions. Many Redmi and budget Xiaomi models feature a microSD card slot. Porting photos, videos and music to an external map is a radical way to solve the space shortage problem.
To transfer data, use the file manager: select files in the internal storage and select "Move" → "SD-Some applications allow you to specify the default save path to the external card in their settings, which is especially true for the voice recorder and camera (although support for recording video on the video). SD model).
The alternative is cloud storage, and services like Google One, Yandex.Disk, or Mi Cloud offer automatic uploading of photos and documents, and by setting up Wi-Fi-only sync and enabling Free Space (removing local copies after downloading to the cloud), you can turn your smartphone into a device with virtually unlimited memory.
⚠️ Note: Memory cards have lower write and read speeds compared to internal memory. It is not recommended to install applications on them or store system files, this can slow down the smartphone.
Regular maintenance of memory of Xiaomi smartphone is not a one-time promotion, but a process. By teaching yourself once a month to check the downloads and cache of messengers, you will avoid critical overflow of memory and maintain a high speed of the device for many years.
