Owners of budget smartphones like the Redmi 7A often face the unpleasant situation when the device suddenly reports a lack of space to install updates or new applications. A small amount of internal memory of 16 or 32 gigabytes is quickly filled with system files, messenger cache and accumulated media content. This leads to a significant slowdown in the MIUI interface and errors when trying to take a new picture or download a file from the Internet.
Timely storage cleaning allows you not only to return performance, but also to extend the life of the gadget, reducing the load on flash memory. In this article, we will discuss in detail the proven methods of freeing up space, ranging from standard system tools to manually removing hidden folders. You do not need to be an IT expert to perform these actions.
Analysis of vault occupancy
Before you start deleting data, you need to understand what exactly takes up precious gigabytes. Android standard tools often show only the big picture, hiding the real "eaters" of space. First, go to the settings menu and select About Phone → Memory, where the system will provide basic information about the distribution of space between applications, images and other files.
However, for a deeper analysis, it is recommended to use the built-in Security app, which is pre-installed on all Xiaomi devices, which allows you to visualize volumes and identify large files that you may have forgotten to delete. Often it turns out that the lion’s share of the space is occupied by social media cache or downloads from the browser.
There are several types of files that can be deleted without fear of system operation, including temporary update files, remnants of deleted programs and duplicate photos. Below is a list of the main categories of garbage that are worth checking first:
- 🗑️ Application cache – temporary data that speeds up programs but inflates to gigabytes.
- 📸 Photo and video duplicates – copies of files created when synchronization fails or re-downloads.
- 📥 Download folder – files downloaded from the Internet and forgotten by the user.
- 📦 APK-Installer files – Application installer packages that are no longer needed after installation.
It is important to understand that system files occupy a fixed volume that is difficult to reduce without deep interference with firmware. The main focus should be on user data. If after a standard cleaning the place still ends too quickly, perhaps the problem lies in the malfunction of the application that creates cyclic logs.
Use of the built-in MIUI cleaner
The easiest and safest way to free up space on the Redmi 7A is to use the regular cleaning tool, which is built into the Security app and optimized specifically for the MIUI shell. The cleaner starts automatically when you open the application, but you need to click on the appropriate icon after you finish scanning.
The system will suggest removing temporary files, app residues and advertising debris, but be careful: sometimes important files are included in the list for deletion if they are in standard cache folders. Always check the contents of the list before confirming a transaction, especially if you have not audited the files in a long time.
☑️ The algorithm of the cleaner
Once the garbage is removed, the cleaner will suggest optimizing RAM memory by closing the background processes, which is useful periodically, since the Redmi 7A has a limited amount of RAM, closing unnecessary applications will free up the processor resources and speed up the interface response.
⚠️ Attention: Deep Cleaning in the Security app may offer to delete large video files. Be careful not to accidentally erase important family archives or work materials.
For users who want to automate the process, the Cleanup Schedule option is available in the cleaner settings. You can set up a weekly scan start at a time when the phone is not in use, for example, at night, to help keep the device clean without the need for manual intervention.
Cleaning the cache of messengers and social networks
Messengers like WhatsApp, Telegram and Viber are the main culprits behind the memory shortage on small-drive smartphones, which store every photo, video and voice message viewed in the device’s memory, and over time, folders with media files can grow to 5-10 gigabytes, a critical volume for the Redmi 7A.
Unlike simply removing an app, clearing the cache through settings allows you to save correspondence but get rid of accumulated visual debris. Telegram, for example, has a built-in feature called Memory Use, which allows you to configure cache autodeletion. It is recommended to set a limit, for example, 1 GB, or configure the deletion of media files older than 3 days.
WhatsApp has a slightly different procedure. You need to go to Settings → Data and Storage → Storage Management. Here you will see a list of chats sorted by space you occupy, you can selectively delete media files from specific dialogues without touching text correspondence.
- 📱 Telegram: Settings → Data and memory → Use of memory → Clear the cache.
- 💬 WhatsApp: Settings → Data and storage → Storage management.
- 📞 Viber: More → Settings → Memory. → Clear the cache.
- 📷 Instagram: Settings → Annex → Warehouse → Clear the cache (via Android settings).
Why does the cache take up so much space?
Regularly checking these settings will help keep your space under control, and if you're a social media user, it makes sense to turn off auto-save media files to your phone gallery, which will prevent duplicate files and keep your album clean.
Working with folders and system files
For more advanced users who are not afraid to work with the file system, it opens up the possibility of manual cleaning. Using the built-in File Explorer or a third-party manager like Total Commander, you can find and delete files that are not visible by standard means. Special attention should be paid to the folder Android/data, where game and application data are stored.
Inside this directory, you can often find folders with the names of remote games that take up gigabytes of space. MIUI/debug_log, And that's where the logs of the system's errors sometimes accumulate, and deleting them is safe and can free up a few hundred megabytes.
| folder | Description of the contents | Can I remove it? |
|---|---|---|
| DCIM/.thumbnails | Miniatures of photos in the gallery | Yes (recreated) |
| MIUI/debug_log | System logs for debugging | Yes. |
| Android/obb | Cache of heavy games and applications | Only if the application is removed |
| Download | Downloads from the browser | Yeah, after the check. |
When working with system directories, it is important to be careful: Deleting files from the root folders of the system can lead to unstable MIUI. Always check what exactly you are going to delete, and make sure that it is not a system file.
⚠️ Warning: Never delete folders with the names of Google or Xiaomi system services (e.g. com.android.providers.downloads) unless you are 100% sure of their purpose.
You can use the size-sorting function in any file manager to find the largest files, and it often turns out that the place is occupied by forgotten movies or archives that were downloaded a few months ago, and moving those files to a memory card or to the cloud is a great solution.
Optimization of photo and video storage
Media files are the heaviest content on any smartphone. With the Redmi 7A camera, the resolution is not extreme, but with active use of the gallery, the best way to solve this problem is to use cloud services like Google Photos or Yandex.Disk.
By setting up automatic sync to remove a copy from your device, you can free up gigabytes of space with a single click. Google Photos, for example, has a Free Space feature that removes photos and videos from your phone that have already been successfully saved to the cloud.
💡
Use the HEIC format for photos if the camera app supports it. Files in this format weigh half as much as standard JPEGs at the same quality as critical for devices with 16 GB of storage.
You should also pay attention to the settings of the camera itself. If you don't plan on printing large-format photos or editing them on a computer, you can reduce the resolution or video quality. Recording video in 1080p instead of 4K (if available) will save a lot of space.
Another life hack is cleaning the Recycle Bin folder regularly in the gallery, and often the deleted photos don't disappear completely, but instead move to a basket where they're stored for 30 days, and once you clean this folder, you'll instantly get back the space you've taken.
Removing Unused Applications and Games
On budget devices, every megabyte counts, so having a dozen rarely used apps is a luxury that Redmi 7A can't afford.
Pay special attention to pre-installed games and services, which often come bundled with firmware. While some system applications cannot be removed without root rights, most user programs are easily dismantled through the application management menu.
To remove, go to Settings → Apps → All apps. Sort the list by size or usage date. If you see a game you haven't played in six months or a food ordering app you use once a year, delete. Install it again is always faster than looking for a new important file.
💡
One month rule: If you haven't opened an app in 30 days, chances are you don't need it. Uninstalling such programs is the quickest way to free up space and speed up your phone.
Remember that even after deleting the application, their “tails” – folders with data and cache – may remain, so after a mass uninstallation, it is recommended to start the cleaner again to remove the residue.
Use of microSD memory card
One of the main advantages of the Redmi 7A is the availability of a microSD card slot, which is a salvation for owners of versions with 16 or 32 GB of internal memory. Proper use of an external card allows you to transfer all heavy files to it: music, movies, documents and even some applications.
To save new files to the card by default, you need to change the settings in the storage menu, but it is worth remembering that the memory card’s speed is lower than that of internal flash memory, so launching heavy games from the card can be slower.
When buying a card, pay attention to the speed class (Class 10 or UHS-I is recommended) so as not to slow down the smartphone. Cheap cards can quickly fail when actively recording, so you should not save on this component.
⚠️ Warning: Before removing the memory card, always use the "Disable" command. SD-map in the settings, otherwise the files can get damaged, and the device - hang.
Transferring apps to a memory card in modern versions of Android is limited, but for media files it is ideal.Tune the camera and voice recorder to store data immediately on the external medium, and the internal memory will remain free for the system to work.
