Smartphone Xiaomi Redmi 7A has long remained a popular budget solution due to its reliability and long battery life. However, owners of this model often encounter one common problem - the internal memory quickly fills up. A storage capacity of 16 or 32 gigabytes in modern realities is consumed very quickly, especially taking into account the constant updating of instant messengers and social networks. When the free space runs out, the device begins to work slower, freeze, and new applications simply refuse to install.
Effectively clearing memory on Redmi 7A requires an integrated approach, since simply deleting a few photos is often not enough. It is necessary to deal with the system cache, hidden messenger folders and duplicate files that have been quietly accumulating for months. In this article, we will look in detail at how to safely and most efficiently free up gigabytes of usable space, returning your phone to its former performance without losing important data.
Analysis of the current storage state
Before you start deleting files, you need to understand exactly what is taking up space in the memory of your device. The MIUIshell, which is installed on Redmi 7A, has a built-in powerful tool for analyzing disk space. Go to menu Settings, then select item About phone and click on section Memory. Here the system will clearly show the distribution of data by category: applications, images, video, audio, etc.
Pay special attention to the “Other” section. Often this is where gigantic amounts of data are hidden that the system cannot automatically classify. These could be archives, firmware update files, or database backups. If the “Applications” category takes up the lion’s share of memory, it may be worth reviewing the list of installed software. Some apps that you have not used for months can weigh hundreds of megabytes along with their data.
⚠️ Attention: Do not delete files from system folders if you are not 100% sure of their purpose. Erroneously deleting system libraries can lead to unstable operation of the interface or even to “bricking” the device.
For a more detailed analysis, you can use third-party utilities, for example, DiskUsage, which visualize memory in the form of a block map. This allows you to instantly find the “heaviest” files hidden deep in directories. However, standard tools are usually quite sufficient to solve basic optimization problems on the model. data-i="52">Games and applications MIUI usually quite sufficient for solving basic optimization problems using a model Redmi 7A.
Clearing the application cache and system garbage
The fastest way to free up space is to clear the cache. Cache are temporary files that applications create to speed up their work. Over time, these files accumulate and can take up gigabytes of space, especially in browsers, YouTube and social networks. On Xiaomi Redmi 7A this procedure can be performed through the built-in "Security" application, which is pre-installed on the system.
Launch the application Security and select the tool Cleaning. The system will scan and offer to remove garbage. It is important to understand the difference between cache and application data. Clearing the cache is safe and will not delete your logins or conversations, while clearing the data will return the application to its “as-installed” state. For deep cleaning, go to Settings → Applications → All applications.
- 🗑️ Sort the list of applications by memory size to find the most “voracious” ones consumers.
- 📱 Select an application, for example Chrome or Telegram, and click the "Clear cache" button in the storage menu.
- 🔄 Repeat the procedure for all heavy applications, but avoid clearing Google system services data.
Regularly clearing the cache helps maintain the performance of RAM the processor, since the system does not have to index unnecessary files. On budget devices with limited storage space, such as Redmi 7A, this procedure should become a weekly habit. If an app's cache is constantly growing to an inadequate size, it may be worth reinstalling it.
Use the Deep Clean function in the Security app once a month to search for forgotten APK installation files and empty folders.
Optimization instant messengers: WhatsApp and Telegram
Messengers are the main enemies of free memory on modern smartphones. WhatsApp and Telegram by default they save all received photos, videos and voice messages to the internal memory of the device. With its modest storage capacity, this quickly leads to a critical situation. Fortunately, both applications have built-in tools for managing storage. Xiaomi Redmi 7A with its modest storage capacity, this quickly leads to a critical situation. Luckily, both apps have built-in storage management tools.
In Telegram the situation is solved most elegantly thanks to the cloud-based nature of the messenger. Go to Settings → Data and memory → Memory usage. Here you can set a limit on the cache size, for example up to 500 MB. Also turn on the Auto Delete Media feature so that old files are erased automatically. All media files will remain on Telegram servers and will be downloaded again by click.
With WhatsApp things are more complicated, since local storage is used here backups and media. Go to Settings → Data and storage → Storage management. You will see a list of chats sorted by space. You can selectively remove heavy attachments from specific conversations without deleting the conversation itself. It is also recommended to disable autosaving of media to the gallery in the settings of each chat.
| Option | Telegram | Recommendation for Redmi 7A | |
|---|---|---|---|
| Media storage | Local (on the phone) | Cloud (on the server) | Regularly clean the WhatsApp/Media folder |
| Auto-delete | No (manual only) | Yes (flexible settings) | Set cache limit to 200-500 MB |
| Backups | Take up memory space | Does not take up space | Transfer WhatsApp backups to Google Drive |
⚠️ Attention: Before mass clearing media files in messengers, make sure that important photos and documents are saved in another location, since restoring deleted local files is impossible.
Another one an important point is the folder .Statuses in the WhatsApp directory, where all viewed contact statuses are saved. These files often weigh a lot and are not needed by the user. They can be safely deleted through any file manager, having first enabled the display of hidden files.
☑️ Monthly cleaning of messengers
Working with the gallery and duplicate files
Photos and videos are the most voluminous type of data for most users. The camera Redmi 7A takes pictures of quite acceptable quality, but one minute of high-resolution video can weigh more than a thousand books. Regular audit of the gallery is necessary. Do not rely only on visual viewing, use duplicate search tools.
The application Gallery from Xiaomi has a built-in search function for similar images. The algorithm analyzes the images and suggests removing blurry frames or duplicates, leaving only the best option. This is especially true if you like to take burst photos. It is also worth checking the folder Screenshots, where unnecessary screenshots of the interface or correspondence often accumulate.
For video files, the best solution is to transfer them to external media or to the cloud. The built-in memory Xiaomi Redmi 7A is not intended for storing archives of family videos over several years. Use services Google Photos with the “Space Saving” compression function, which allows you to store an unlimited number of photos and videos in the cloud for free (in a certain quality).
- 🖼️ Delete all blurry and unsuccessful photos immediately after shooting, without delaying for later.
- 🎥 Switch the camera to space saving mode or reduce the video resolution to 720p if 1080p quality is not critical.
- ☁️ Set up automatic synchronization of the gallery with cloud storage and enable the “Free up space” function.
Don’t forget about the folder Download (Downloads). This often includes application installation files, PDF documents and pictures from the Internet, which the user forgets about after a day. Sorting files by size in this folder helps you quickly find and delete unnecessary gigabytes.
Transferring applications and data to a memory card
The model Xiaomi Redmi 7A supports the installation of memory cards of format microSD, which is a salvation for owners of versions with 16 or 32 GB of internal memory. Correctly setting up the card allows you to transfer most of the user data, freeing up precious internal space for system operation.
In modern versions Android i MIUI transferring entire applications to a memory card is unstable or limited by the developers of the applications themselves. However, you can configure the card as a "Portable Storage" and manually transfer all media files there. In the storage settings, select a memory card and specify it as the default recording location for the camera and voice recorder.
To transfer existing files, use the built-in explorer Explorer. Select the folders DCIM, MIUI (partial), Music and Download, then select “Move” and specify the path on the SD card. This action will instantly free up several gigabytes in the internal partition.
Is it possible to make a memory card into internal memory?
The Adoptable Storage function (when the card becomes part of the system) in the MIUI shell is officially disabled. There are ways to activate via ADB commands, but this reduces the speed of the card and increases the risk of data loss if a failure occurs. For Redmi 7A, it is safer to use the card as external storage for media.
When choosing a memory card, pay attention to the speed class. For comfortable work with photos and videos, we recommend a class card UHS-I U3 or A1. Slow cards can cause delays when opening the gallery or playing a video, which will create a false impression that the smartphone itself is slow.
Using a microSD card to store media files is the most effective way to expand the memory on Redmi 7A without losing system performance.
Resetting settings as a last resort optimization measure
If all of the above methods did not help and the phone continues to signal that there is not enough space, perhaps the system has accumulated a critical amount of errors or hidden garbage that cannot be removed manually. In this case, the only effective solution is a full reset to factory settings. This procedure will return Redmi 7A to the state it was in immediately after purchase.
Before performing a reset, it is critical to create a complete backup of all data. Use account Mi Account or Google Account to synchronize contacts, notes and settings. Be sure to copy photos and documents to your computer or to the cloud, since after the reset the internal memory will be completely cleared.
To reset, go to Settings → Advanced settings → Restore and reset. Select Reset settings and confirm deleting all data. The process will take a few minutes, after which the phone will reboot. You will need to go through the initial setup again and enter your account information.
⚠️ Attention: Make sure the battery charge is at least 50% before starting the reset. Interrupting the recovery process due to low battery may damage the software.
After the reset, do not install all applications back at once. Try using the phone in a “clean” state for a couple of days. It often turns out that you don’t actually need half of the previously installed software. This will help prevent the memory from quickly refilling.
Prevention and good habits
To prevent the problem of lack of memory on Xiaomi Redmi 7A from returning, it is necessary to develop certain digital habits. Regularity is more important than one-time cleaning actions. Spend 10 minutes once a week checking your downloads folder and messenger cache. This will take less time than the subsequent struggle with the slow interface.
Stop storing offline maps and music if you have stable mobile data. Streaming services allow you to listen to music without downloading files, and navigators work online. If offline mode is necessary, limit downloading maps only to those regions where you are planning a trip in the near future.
Keep an eye on system updates MIUI. Sometimes new firmware versions optimize the operation of the file system and improve cleaning algorithms. However, before a major update, always make sure that you have at least 1-2 GB of free space, otherwise the installation process may fail.
Frequently asked questions (FAQ)
Why is the space not freed up after deleting files?
Check the trash in the Gallery or Explorer application. On modern versions of MIUI, deleted files first go to the trash, where they are stored for 30 days. To free up space instantly, you need to empty the trash as well.
Is it possible to delete Xiaomi system applications?
Most system applications (Themes, Music, Videos) can be disabled in the settings, but cannot be deleted without root access. Disabling them will hide them from the menu and stop them running in the background, which will free up some resources, but not memory. Complete removal requires connecting to a PC and using ADB commands, which is not recommended for beginners.
How to transfer WhatsApp to a memory card on Redmi 7A?
You cannot transfer the application entirely. But you can transfer media files. In your phone settings, change the default save path to SD card. Old files will have to be moved manually through Explorer from the internal memory to the corresponding folders on the card.
What is a swap file and can it be deleted?
The swap file (swap) is used by the system to expand RAM at the expense of internal memory. On Redmi 7A with a small amount of RAM, it can take up to 1-2 GB. It is not recommended to remove it manually, as this will cause applications to crash. It is better to close background apps.
Why does the “Other” section take up so much space?
In the “Other” section, the system includes files that it cannot identify: the cache of streaming services, game data, temporary update files and the remains of deleted applications. Cleaning through the app menu or resetting settings is the best way to reduce this partition.
