Redmi series smartphones are deservedly popular due to their excellent value for money, but the Redmi 7 model, released on the basis of the Snapdragon 632 processor, may eventually begin to experience a shortage of RAM. Owners often notice that the MIUI interface begins to slow down and applications load longer than usual. It is a natural process of accumulation of digital debris that requires user intervention to restore the original performance of the device.
The main reason for the slowdown is the overflow of the system partition and fragmentation of the application database. When the free space on the internal drive falls below the critical mark of 10-15%, the Android operating system begins to work in stress test mode, constantly trying to find space for temporary files. Deep cleaning in this case is not just deleting photos, but complex work with cache, residual files of remote programs and system logs.
Before embarking on radical measures such as a full reset, you need to audit files manually and with built-in tools.The right approach allows you to free up gigabytes of space without losing personal data. In this article, we will discuss safe methods that will help your Redmi 7 fly again, as on the first day after purchase.
Analysis of storage filling and search for hidden files
The first step to optimizing is to make a detailed diagnosis of what exactly takes up space. MIUI has an inbuilt analyzer, but it often only shows the big picture. To get a deeper understanding of folder structure, it is recommended to use visualized file managers, such as Files by Google or Total Commander, which allow you to see the real size of folders that the system hides in the standard menu.
Special attention should be paid to the folders of messengers, since WhatsApp and Telegram tend to accumulate media files for years. /Android/media/ Hundreds of megabytes of videos and images are stored, and cleaning up the cache of these applications can instantly release the data from the data. 2 before 5 GB space, which is critical for budget models 32 GB of memory.
⚠️ Warning: When deleting files from system folders, be extremely careful. Never delete the contents of folders called system, data, or files with the.apk extension, the origin of which you are not sure by 100%.
You can manually search for heavyweights by size, open a standard explorer, select size by size, and carefully examine the top of the list, often with forgotten downloads, offline maps of navigators, or cache streaming services like Spotify or YouTube.
💡
Check Downloads periodically. Many users forget that downloaded application installation files (.apk) stay there forever, taking up space even after installing programs.
Use of the built-in "Security" application
Xiaomi preinstalles a powerful system tool called Security on its devices, not just an antivirus, but a complete processor to maintain the system. To start the cleaning process, find the green shield icon on your desktop and press the Cleanup button. The system automatically scans the device for temporary files, installer packages and advertising debris.
Inside the app, there's a Deep Clean section that allows you to manage the storage in more detail, where you can safely delete large files, duplicate photos and unused applications. The tool's algorithm takes into account the specifics of the MIUI file system, so it's safer than third-party counterparts, which can mistakenly delete the system logs necessary for stable operation.
☑️ Verification through the Security Application
It's important to understand the difference between cleaning up your cache and cleaning up your data. When you select an app in the list and click "Clean up," the system will offer two options. Cache cleanup deletes temporary files (pictures, scripts) without affecting your logins and settings. Data cleanup resets the app to a "just out of the store" state, removing all accounts and progress. Most of the time, the first option is enough to speed up work.
Cleaning messengers: Telegram and WhatsApp
Messengers are the main memory eaters on Redmi 7 smartphones. Unlike iOS, where the cache is cleaned more aggressively, in Android, these apps save every open picture and video for quick re-access. Telegram has a built-in mechanism for this: go to Settings → Data and memory → Memory Use and set a cache limit, for example, 500 MB. It is also recommended to enable the “Autodele Media” feature for old chats.
With WhatsApp, the situation is more complicated, as the app backs up locally. Go to Settings → Chats → Backup Chats and check the file size. If it is too large, delete old backups through the file manager on the way /sdcard/Android/media/com.whatsapp/WhatsApp/Databases. Leave only the latest file and delete the rest to free up space.
| Type of data | Wherever | Can I remove it? | Impact on work |
|---|---|---|---|
| Cash images. | /Android/media/... | Yes, it's safe. | Accelerating the opening of the gallery |
| Chat databases | /Databases | Only the old ones. | Liberation of the place |
| Uploaded documents | /Downloads | Yeah, unless you have to. | Liberation of the place |
| .nomedia files | In the photo folders. | No. | Hiding folders from the gallery |
⚠️ Before cleaning the databases of messengers, make sure that important correspondence is stored in the cloud or is not of value to you.
Telegram users also need to clean up their feed folders, so if you're in dozens of channels, the app caches content from all of them, and use Clear Cache within the app's settings, rather than through the system menu, so that the messaging database doesn't work.
Removal of system debris and residual files
Even after deleting applications, the system still has tails — empty folders, configuration files and error logs. On Redmi 7, with its limited memory, every megabyte in your account — you can use the built-in Delete Apps feature in your settings, which shows apps that haven’t opened in a long time to find those files.
There is also a hidden cleaning section that can be accessed through the engineering menu, but it is safer for the average user to use third-party utilities like SD Maid (the free version has limited functionality but is sufficient). It finds CorpseFinder, files left over from remote programs. Manual cleaning requires care: delete only those folders whose name matches the name of the remote application.
Should you use the accelerators from the Play Market?
Don't forget the folder. MIUI/debug_log. It can accumulate debugging logs that take up a significant amount of space. → MIUI → debug_log. If you are not a developer and do not debug the system, the contents of this folder can be painlessly deleted.
Optimizing MIUI and disabling animations
Cleaning up memory is only half the battle. 7 It was faster, we need to reduce the load on the GUI. MIUI It's famous for its beautiful but heavy animations, and turning them off will visually speed up the system response. → On the phone and press quickly 7-10 once on the line “Version MIUI».
After activating the developer mode (the corresponding notification will appear), go to Settings → Advanced Settings → For developers. Find the section “Drawing” and change the scale of the animation:
- 🎨 Windows animation: install 0.5x or off.
- 🔄 Transition animation: install 0.5x or off.
- ⏳ Duration of the animator: set 0.5x or off.
Also in this menu, it is recommended to find the item "Background process" and limit the number of background processes to 2-3 pieces. This will free up RAM for active applications, which is critical for models with 2 or 3 GB of "rAM".
💡
Turning off animations doesn’t physically speed up the processor, but makes the interface visually responsive, reducing the waiting time for windows to open.
Radical measures: Resetting to factory settings
If the software cleaning failed and the phone continues to slow down, the last effective method is a full reset, which will return the software to the “out of the box” state by removing all the accumulated registry errors and file conflicts over the years.
To perform the reset, go to Settings → About Phone → Settings Reset. Select “Erase All Data.” The phone will reboot and begin the cleaning process, which can take anywhere from 10 to 30 minutes. Don’t interrupt the power of the device at this point, as this could damage the bootloader.
⚠️ Warning: After a reset, do not restore apps wholesale from a Google Play backup in the first minutes. Install only the essentials manually. Often, it is the older versions of apps that are restored by the backup that carry conflicting settings.
Once reset, the system will work as fast as possible. To maintain this effect, try not to fill the internal memory "to the end." Always leave at least 3-4 GB of free space for the correct operation of the paging file and system.
