Smartphone Redmi 7, released in 2019, still remains a popular device due to its reliability and autonomy. However, today's applications are becoming more resource-hungry, and the built-in 32 or 64 gigabytes of memory may fill up faster than you expect. When the storage is full, the system begins to work slower, notifications about low space appear, and installing new apps becomes impossible.
Effective memory cleaning on Redmi 7 requires an integrated approach: from simply deleting unnecessary files to deep optimization of system partitions. In this article, we will look at proven methods for freeing up space that will help restore your device to its former speed without losing important data. You will learn how to properly use the built-in MIUI tools and third-party utilities for maximum results.
Analyzing the fullness of the internal storage
Before deleting files at random, you need to understand what exactly takes up the lion's share of space. The shell MIUIinstalled on Redmi 7 has a built-in analyzer that clearly shows the distribution of data. Go to the settings and find the section responsible for storage to see detailed statistics by category.
Most often, space is occupied by multimedia files, messenger caches and installed games. The system may show that the "Other" section takes up several gigabytes. This is a collective category that includes system logs, temporary files and application data that did not fall into the main categories. Understanding the memory structure is the first step to competent optimization.
⚠️ Attention: Do not delete files from system folders if you are not sure of their purpose. An error can lead to unstable operation of the interface or loss of settings.
Pay attention to the DCIM and Telegram folder - this is where gigabytes of forgotten videos and images most often accumulate.
For a more detailed analysis, you can use third-party file managers that visualize data in the form of charts. This allows you to quickly find the largest files that could be lost in the depths of directories. For example, a forgotten high-definition movie or an archive of documents may take up space that you don’t even know about.
Using the built-in Cleanup application
Each device Xiaomi has a pre-installed Security utility that contains a powerful tool for removing junk. Launch the application and select the cleaning option. The system will automatically scan the device for temporary files, remnants of uninstall packages and advertising cache.
After scanning, you will see a list of files that can be safely deleted. Typically these files range in size from several megabytes to gigabytes. Click the clean button to free up space. This method is the safest for beginners, since the algorithms MIUI do not suggest deleting important system components.
- 🗑️ Removing the application cache - temporary data that slows down work.
- 📦 Remnants of deleted apps - configuration files remaining after uninstallation.
- 📰 Advertising files - garbage accumulated by free applications.
- 📸 Duplicate photos - copies of images created during editing.
It is important to repeat this procedure regularly, especially after actively using the Internet or installing new apps. The built-in cleaner also offers a Deep Clean feature that analyzes large files and rarely used applications. Active use of these tools helps to maintain Redmi 7 in good technical condition.
Clearing the cache of instant messengers and social networks
Messengers like WhatsApp i Telegram are the main memory hogs on modern smartphones. They automatically download all received photos, videos and documents, saving them in the internal memory. Over time, these folders can grow to tens of gigabytes, taking up the space necessary for the system to operate.
To solve this problem, go to the settings of a specific messenger and find the “Data and Storage” section. There you will see the amount of used space and can clear the cache or delete old media files selectively. In Telegram, for example, there is a convenient function for automatically clearing the cache, which can be configured by time or volume.
Settings → Data and storage → Storage used → Clear cacheDo not forget that clearing the cache does not delete your correspondence, but only erases downloaded ones media files from the device. If necessary, you can always download them again from the messenger cloud. This is the most effective way to quickly free up several gigabytes without losing important information.

Transfer photos and videos to the cloud or PC
Multimedia content makes up the bulk of user data. Storing thousands of photos and hours of video on the built-in drive Redmi 7 is impractical, especially given its limited capacity. Transferring archives to external media or cloud services is a radical, but the most effective method.
Modern cloud services, such as Google Photos, Yandex.Disk or MEGAoffer free storage space. Set your photos to download automatically, then use the Free Up Space feature in the app. This will delete local copies of files that are already safely stored on the Internet.
| Service | Free volume | Features |
|---|---|---|
| Google Photos | 15 GB (shared with Gmail) | Smart search, compression without loss of quality |
| Yandex.Disk | 10 GB | Startup from mobile devices, integration with the ecosystem |
| MEGA | 20 GB | High level of encryption, large starting volume |
| pCloud | Up to 10 GB | Virtual disk, convenient work with files |
If you do not trust cloud storages, connect your smartphone to your computer via a USB cable. Copy the folders DCIM, Pictures and Download to your PC hard drive. After checking the integrity of the files on your computer, feel free to delete them from your phone. This will give you back the maximum amount of free space.
Deleting unused applications and games
Often we install applications “one time” or forget about games that we stopped playing. Such apps not only take up space, but can also run in the background, consuming RAM and battery power. Regular revision of installed software is a mandatory procedure for the owner Redmi 7.
Go to the phone settings and select the "Applications" section. Sort the list by size or date of last use. Uninstall any apps you haven't used in the last month. Pay special attention to games - they often weigh 1-2 gigabytes or more.
⚠️ Attention: When deleting system applications (if you have root access), be extremely careful. Removing critical components can lead to “bricking” the device.
How to remove system applications without Root?
To remove system software without superuser rights, you can use the ADB command through a computer. Connect your phone in debug mode and enter the command: pm uninstall -k --user 0 . This will hide the application for the current user, freeing up space, but will not compromise the integrity of the system.
Some applications cannot be completely removed, but they can be “Disabled”. This hides the icon from the menu and prevents the application from launching, effectively freezing it. For built-in Google or Xiaomi services, this is often the only opportunity to free up system resources.
Resetting to factory settings as a last resort
If none of the above methods helped, and the phone continues to signal that there is not enough space, the system may have accumulated critical errors or hidden garbage. In this case, the only effective solution is a full reset to factory settings. This will return Redmi 7 to the condition it was in when purchased.
Before performing this procedure, be sure to back up all important data: contacts, messages, photos and documents. The reset will delete absolutely all information from the internal storage, including accounts and settings. The process takes about 10-15 minutes.
Settings → About phone → Reset settings → Erase all dataAfter the reboot, you will get a clean system with the maximum amount of free memory. Install apps only as needed to avoid quickly filling up your storage. This is a radical, but often the only way to revive an old smartphone.
A hard reset deletes even those files that are not visible in the file manager, including hidden cache and file system errors.
Frequently asked questions (FAQ)
Why is the space not freed up after deleting files?
The files may have been moved to the trash inside a file manager or gallery. Check your Trash folder and empty it. Also, the location may not be displayed immediately due to a delay in system indexing - try restarting the phone.
Is it possible to transfer applications to a memory card on Redmi 7?
The MIUI shell limits the ability to transfer applications to an SD card. Most modern apps do not support this feature. However, photos, videos and music can be safely stored on an external card by setting the camera and instant messengers to save data there.
Is it safe to use third-party cleaning apps like Clean Master?
The use of aggressive cleaners is not recommended. They often consume a lot of resources themselves, show intrusive advertising and can delete necessary files. The built-in MIUI tools are quite sufficient for safe optimization.
What to do if the system says “Insufficient memory” when updating?
To update the system, a significant amount of free space is required (usually 3-5 GB). Try deleting large games and videos, clearing the cache of all applications, or resetting the settings before downloading the update.
