Xiaomi Redmi 7 has become a legend in the budget segment due to its reliability and autonomy. However, over time, even the most powerful Snapdragon 632 processor begins to experience difficulties if internal storage is crowded. When there is critically little space, the MIUI system starts to work slower, applications fly out, and new photos simply cease to be stored. It is a natural process of accumulation of digital debris that every Android device owner faces.
In this article, we’ll look at proven and safe ways to clean up memory on Redmi 7 without deleting important contacts or documents. You’ll learn to distinguish the system cache from important data, find hidden folders with “heavy” files, and understand how to set up automatic cleaning correctly.
Before you start radical measures like factory resets, it's worth trying less painful methods. Often users don't even realize that tens of gigabytes are taking up old messenger dialogues or duplicate photos. Let's figure out where to start vacating space.
Analysis of the occupancy of the storage facilities
The first step is always diagnostics. Android and MIUI provide built-in tools to visualize occupied space. You don't have to download third-party programs right away, because the standard analyzer works fairly accurately. It shows which categories of files occupy the most space: applications, images, video or system data.
To start the analysis, you need to go to the settings menu. Find Settings → About Phone → Storage. Here you will see a color diagram where each sector is responsible for a particular type of data. Blue usually represents applications, green media files, and gray system data and so on. By clicking on any sector, you can go to a detailed list of files.
Note the Other section, which is often where remote application files or residues are accumulated after a system update, and this section should be cleaned carefully, because without understanding the nature of the files, you can delete important configurations, but in most cases, files in the Other category on Redmi 7 are temporary and safe to delete.
⚠️ Note: Do not delete files with the extension.obb or.apk from the system folders unless you are sure that they belong to remote games.
Using the “Security” app and cleaning the cache
Every Xiaomi smartphone has a Security app preinstalled, which is not just an antivirus, but also a powerful memory management tool, and Cleans up scans the device for temporary files, junk, and residual data, and is recommended to run this procedure regularly, at least once a week.
Once scanned, the system will suggest removing the debris found. Press the Clean to make room. However, this is only the tip of the iceberg. For a deeper cleaning inside the Security app, there is a Cleanup section where you can select specific file types: Application cache, installer packages, unused APK-Application cache is temporary data that speeds up the launch of programs, but over time can grow to gigabytes.
Special attention should be paid to clearing the cache of specific “heavy” applications, such as browsers or social networks. Go to Settings → Apps → All applications, select the right one (for example, Chrome or Yandex) and click Storage. There will be a button Clear cache. It is important not to confuse it with the “Clean everything” button (or “Erase data”), since the second option will remove your logins, passwords and settings inside the application.
☑️ Weekly cleaning of Redmi 7
Sometimes, after cleaning the cache, applications can load a little longer on the first run, which is normal, because the system needs to re-form temporary files, and if after cleaning the problem with space shortages is not solved, then the main memory eaters are located elsewhere, for example, in multimedia or duplicates.
Working with multimedia: photos, videos and duplicates
Media files are the main enemy of free memory on Redmi 7. The camera of this smartphone takes high-quality pictures that take up considerable volume. In addition, users often forget about videos that can "weigh" hundreds of megabytes each. The standard MIUI gallery has a built-in tool for finding similar and blurred photos, which helps to quickly get rid of visual noise.
You can use a file manager to find duplicates. Open Explorer and go to Analysis (or Files → menu → Clean) and find the same images and suggest that you delete them. It's also worth checking DCIM →.thumbnails. This hidden directory stores thumbnails of your photos for quick display in the gallery. Over time, thumbs.db or its Android counterpart can grow to several gigabytes.
Deleting the.thumbnails folder is safe, the system will recreate it, but it is smaller, so you need to turn on the hidden files in the file manager (usually in the Explorer settings) and find this folder, and after cleaning the gallery can load the preview again for a few seconds, but the space will be freed up.
Where do the deleted photos go?
Don’t forget messengers. Telegram and WhatsApp store all the photos and videos you’ve viewed in your phone’s memory by default. Telegram’s settings have a Data and Memory section → Memory Use, where you can clear the cache with a single tap and limit the autoload of media. This can free up to 5-10 GB of space on your device.
Removal of unused applications and their residues
Apps are not just the installation files themselves, but the data they accumulate. On Redmi 7, with its modest internal storage capacity (32 or 64 GB), installing heavy games and social media quickly leads to overcrowding. Regular auditing of installed programs is a must-do procedure.
Go to Settings → Apps → All Apps. Sort the list by size. You will be surprised to find that a long-abandoned game or food delivery app takes up more space than all your music. Delete what you haven't used in the last 3-4 months. For system applications that can't be removed in the standard way, you can use the Disable feature, which will hide them and stop the background processes.
When you delete an application, you often have folders with its name in the root of internal memory or in the Android/data folder. Manually check the file manager for folders with the names of remote programs (for example, if you deleted the game from Gameloft, check the Gameloft folder), their removal is safe and returns precious megabytes.
| Type of data | Wherever | Security of removal | Recommended method |
|---|---|---|---|
| Cash app. | Settings / Security | Tall. | Cleaning through the app menu |
| Folder.thumbnails. | DCIM /.thumbnails | Tall. | Manual removal through the conductor |
| APK files | Downloads / Download | Tall. | Removal after installation of programmes |
| Game Data (OBB) | Android / obb | Low (for remote games only) | Removing Remote Games Folders |
💡
Use the "Twin Apps" feature with caution: Cloned social networks create a separate cache and take up almost as much space as the original, which is critical for Redmi 7.
Transferring data to memory card and cloud services
Xiaomi Redmi 7 has a separate microSD card slot, which is a huge plus: transferring photos, videos and music to an external card is the most efficient way to offload internal storage. Internal memory is faster, but it needs to be saved for the system and applications.
To transfer files, open Explorer, select the files you want (for example, all videos from the Camera folder), click the menu (three dots) and select Move. SD-After transfer, set the camera and messengers to save new files immediately to the memory card. SD-map that needs to be activated.
An alternative to a physical map is cloud services: Google Photos, Yandex.Disk or Cloud Mi. By setting up automatic synchronization with the subsequent removal of local copies, you can store terabytes of data in the cloud, leaving only thumbnails on the phone. The “Free space” function in Google Photos does this automatically.
⚠️ Note: When transferring data to SD-Make sure it is good and has a high recording speed (grade 10 or higher) and a slow card can cause delays when shooting videos or viewing photos.
Radical measures: Resetting to factory settings
If none of the above methods worked and the memory fills up on its own (which may indicate a file system error or a log failure), the last option is a complete reset. This procedure will return the Redmi 7 to the “out of the box” state, removing absolutely all user data, applications and settings.
Before starting the procedure, it is critical to back up. → The phone. → Reservation and restoration. SD-card or computer. Then go to Settings. → Advanced settings → Recovery and discharge → Reset settings. The system will request confirmation and password from the Mi Account.
Once reset, the phone will work as fast as possible, as all the accumulated registry errors and fragmentation of files will disappear over the years of use. However, frequent use of this measure is not recommended, as it is stressful for the device's flash memory.
💡
Wipe Data is a last resort, and before using it, make sure to check whether hidden system error logs that can be deleted via Engineer Mode or ADB are filling the memory.
