Owners of budget smartphones like the Xiaomi Redmi 7A often face a lack of space after months of active use. Limited built-in storage of 16 or 32 gigabytes is quickly filled with system updates, multimedia files and social media data. When the free space runs out, the device starts to run slower, applications fly out, and new programs stop being installed.
Fortunately, the Android operating system, combined with the MIUI shell, provides the user with powerful tools for managing files. You don’t need to be a technical specialist to conduct a deep cleanup. In this article, we will discuss all effective methods for freeing up disk space, from standard system tools to advanced garbage management techniques.
Before starting the procedure, it is important to understand which data can be deleted without risking the stability of the gadget, and which cannot be touched categorically. The system partition requires careful handling, while folders with temporary files can be cleaned regularly. The right approach will allow you to return the performance of your Redmi 7A and forget about the constant notifications of space shortage.
Analysis of vault occupancy
The first step is always to diagnose, to know exactly what the lion's share of your disk is. MIUI There's a built-in analyzer that visualizes file allocation. Go to Settings menu. → Memory to see detailed statistics by category: apps, images, videos, documents, and more.
Often, it turns out that the main problem is not installed programs, but their cache and downloaded files in messengers. WhatsApp and Telegram can cover several gigabytes, saving all the photos and videos viewed. The system will show you the exact amount occupied by each application, which will identify the main “eaters” of memory.
⚠️ Note: Do not delete files from system folders with names like Android, MIUI Or System, if you're not 100% sure about their content, it could cause the interface to crash.
For deeper analysis, you can use third-party tools like DiskUsage or embedded Explorer, which map the memory card as a diagram, where the square size corresponds to the file size, to help you find forgotten archives or high-resolution video files that have been lost in the back of the directories.
Use of the built-in “Cleanup” application
The easiest and safest way to get started is to use Xiaomi’s regular tool, which is called a Cleaner app, and it’s usually located in the Tools folder on the home screen, which scans the device for temporary files, residual debris after deleting programs and large files.
Run the scan and wait until it's done, and the system will suggest removing the debris that you find that doesn't affect your phone, but don't blindly trust the automation: look carefully at the Big Files list, and there may be important documents or personal videos that you didn't plan to delete.
☑️ Quick cleaning algorithm
In the Cleanup settings, you can enable automatic cleaning. To do this, go to the app menu (three dots or gear) and activate the Auto Cleanup option. The phone will self-clean up a space when free memory becomes critically scarce, for example, less than 10%.
💡
Turn on the large file notification in the Cleanup settings, which will help you respond to the appearance of high-resolution, voluminous videos in time.
Cleaning the cache of applications and data
Cache is temporary data that apps save to make it work faster. It grows to a huge size over time, especially in browsers, YouTube, Instagram, and TikTok. To clear the cache of a particular application, go to Settings → Apps → All apps, select the right one, and click Clear → Clear cache.
It's important not to confuse cache with user data. If you choose "Clean it all" or "Clean it up," the app will return to a state immediately after installation: you will crash out of your accounts, save games and settings will disappear, and only do this if the program is not working properly or you want to reset it completely.
| Type of data | What's removed | Is it safe? | Impact on the account |
|---|---|---|---|
| Cash. | Temporary files, thumbnails | Yeah, totally. | No influence. |
| Application data | Logins, settings, saves | Only with a backup copy. | Full exit. |
| Deletion of the annex | All content of the program | Yes. | Re-entry required |
You can use the developer menu to quickly clear the cache of all applications, but Redmi 7A makes it easier to use the Deep Clean feature in the standard security application, automatically finding apps with bloated cache and prompting them to clean with a single click.
Working with WhatsApp and Telegram messengers
Messengers are the main culprits behind memory overflows on Redmi 7A. These apps save every photo and video you receive to the gallery, even if you just opened it and forgot it. In Telegram, you need to go to Settings → Data and memory → Memory Use and click Clear Cache. You can also set up autodelete media files in 3 days or a week.
On WhatsApp, the situation is similar: Open a chat with the most active contact or group, click on the name of the person, and select Media, links and documents. Here you can select all files older than a certain period and delete them. Also, in the WhatsApp settings, there is a Data and Storage item where you should turn off auto-save to the gallery.
Where are WhatsApp files stored on Redmi 7A?
Remember the Documents tab in messengers. Often users pass heavy messages to each other. PDF-files or archives that lie dead for years, occupying precious megabytes on a budget device.
Removal of duplicates and large files
When you use a smartphone, you often make copies of files. For example, you could save a photo from the Internet and then send it to the messenger by creating a copy. It's convenient to use a built-in Explorer to find such duplicates on Redmi 7A. Open the Explorer app, select size sorting, and delete unnecessary repetitions.
Pay special attention to the Download folder. Browners and social networks often save APK installation files that are no longer needed after installing the program, or banner ads. Regularly checking this folder is a great habit for maintaining order.
- 📸 Screenshots: Screenshots folder is often crammed with superfluous interface images that have no value.
- 🎥 Video: Video format takes up the most space. Check folder DCIM Remove the lost or failed videos.
- 📁 Archives: Files with the.zip or.rar extension may contain game installers or old backups.
If you find a file that is pathetic to delete, but rarely needed, consider transferring it to cloud storage, such as Google Drive or Yandex.Disk. Redmi 7A allows you to set up automatic synchronization of photos through Google Photos with the “Free space” function, which will remove the originals from the device, leaving them in the cloud.
💡
Regularly searching for files larger than 100MB allows you to quickly find and delete forgotten videos or archives, freeing up gigabytes of space in a couple of minutes.
Removing Unused Applications and Games
Modern mobile games weigh a lot. One installation file can take 2-3 GB, and with cache and data, even more. Go through the list of installed programs in the Settings menu → Apps and sort them by size. If you haven't run a heavy game in the last two months, it can be safely deleted.
Notice the pre-installed Xiaomi apps you don't use, some of which can be removed completely, others can only be disabled, and the app that is disabled stops updating and consuming resources, although it remains in the system. Removing standard programs may require a computer connection and use ADB-commands, because MIUI Protects its system components.
⚠️ Warning: Before removing an unknown system application, be sure to check its name in the search engine. UI Security or security can lead to an endless restart of the phone (bootloop).
Also worth checking out is the list of Sleeping Apps. MIUI has a feature that limits the background activity of rarely used programs.This won't remove them, but will prevent cache bloating in the background, which indirectly helps save space and battery power.
Transfer data to memory card and cloud
Redmi 7A Supports microSD cards up to 256GB. This is the best solution to space shortage. You can transfer all photos, videos, music and documents to the map. To do this, insert the card, then in the Explorer app select files and use the Move to the map function. → SD-map.
Unfortunately, transfer the applications themselves to the memory card in modern versions of Android and MIUI But many apps (camera, voice recorder, instant messengers) allow you to choose the way to save new files in your internal settings. Go to the camera settings and specify saving photos and videos on your camera. SD-map.
- ☁️ Google Photos: Enable sync and space saving to automatically compress and delete local copies.
- 📂 File Manager: Use it to packet folder movement DCIM and Pictures on external storage.
- ⚙️ System settings: In some versions MIUI There is a "Memory" item where you can forcibly write data to SD-map.
Using cloud services is also effective. If you have a Mi Cloud, Yandex.Plus or Google One account, set up automatic uploading of photos. Once you successfully upload the originals, you can delete them from your phone, leaving only thumbnails that take up minimal space.
