Owners of the popular budget smartphone Xiaomi Redmi 7 often face a lack of free space to install new applications or save photos. The standard 32 gigabytes of internal memory are quickly filled with system files, messenger updates and accumulated social media cache, which leads to a slowdown of the device and the appearance of annoying notifications about the lack of space.
However, there are many effective ways to free up precious megabytes without losing important data. System optimization allows you to return the device to its former sharpness and responsiveness. In this article, we will discuss in detail the proven methods of cleaning storage that are suitable for the architecture of the Snapdragon processors installed in this model.
Many users mistakenly believe that the only way out is to buy a new gadget, but fine-tuning the software part works wonders. We'll look at both the regular tools of the MIUI shell and more advanced methods of managing files. The right approach to storing data will extend the life of your smartphone for many months.
Analysis of vault occupancy
The first step is always to diagnose, and you need to know exactly what is taking up the lion’s share of your Redmi 7’s resources. Android doesn’t always correctly display the real weight of folders in a standard Explorer, so you should use built-in analytics tools.
Go to the settings menu and select About Phone, then click on Warehouse, and you'll see a colored data distribution diagram here, and it often turns out that half the space isn't taken up by your personal photos, but by a cache of messengers like Telegram or WhatsApp that inflates to incredible sizes.
💡
Use Xiaomi’s built-in Security app for initial scanning – it automatically finds large files and duplicate photos.
Note the Other category, which often hides remnants of deleted applications or temporary update files, and if this category is larger than 5-7 gigabytes, manual cleaning or resetting of heavyweight applications is required.
Cleaning up system debris and cache
The easiest and safest method is to use a regular cleaner. In the Security app, select the Cleanup function. The system will analyze the device and suggest removing temporary files that do not affect the operation of the programs.
Deeper cleaning requires manual intervention in the settings of specific applications. Go to Settings → Apps → All apps. Find the most voracious programs on the list, such as YouTube, Instagram or Chrome browser. Click on the name of the application, select Memory and then Clear Cache.
☑️ Daily Memory Hygiene
It is important not to confuse the Clear Cache button with the Delete Data button. The second option will completely reset the application to factory status by removing your logins, correspondence, and settings within the program. Use it only in extreme cases when the application is not working properly.
⚠️ Note: With complete clearing of messenger data without prior backup, you can irretrievably lose your correspondence history.
Working with multimedia and messengers
The main memory consumers on Xiaomi Redmi 7 are media files received through messengers. Telegram and WhatsApp by default store all the photos and videos viewed in the memory of the phone. This creates thousands of hidden copies that you do not need.
Inside Telegram itself, go to Settings → Data & Memory → Memory Use. You can set a cache size limit, for example, to 500 MB. The system will automatically delete old files when the limit is exceeded, but they will remain available in the chat cloud.
For WhatsApp, the procedure is similar, but requires a visit to the file manager. Find the Android → media → com.whatsapp → WhatsApp → Media folder. Inside, you will find the WhatsApp Images and WhatsApp Video folders, where all the files you receive are stored, and you can safely delete them or transfer them to a memory card.
Remember to check the Download folder, which is often automatically saved documents that are opened from mail or browsers, and they lie there dead weight for years. APK-The installer files will also release a significant amount of.
Use of microSD memory card
Redmi 7 is equipped with a hybrid slot that allows you to use a memory card up to 256 GB. This is the best solution for storing photo archives and video recordings. However, just inserting a card is not enough – you need to set up the system correctly.
Modern versions of Android do not allow you to transfer the applications themselves to the SD-You can move all the media files there, and when you install the card, the system will suggest using it as Portable Storage. You can choose this one to make the card work like a flash drive.
| Type of data | Recommended storage location | Impact on speed |
|---|---|---|
| System applications | Internal memory. | Maximum speed |
| Photos and videos | SD card (Class 10+) | It doesn't affect the OS. |
| Music and books | SD card | Comfortable reproduction |
| Navigator cache | SD card (in settings) | Minimum impact |
To transfer existing files, use the file manager. Select the DCIM, Pictures, Music folders and move them to the root of the memory card. Then, in the camera settings, specify saving new images to an external medium.
What is an exFAT file system?
Removing duplicates and hidden files
When you use your smartphone, you accumulate duplicate images of the same images in your memory, so you could download a picture from the Internet, save it for notes, and then send it to the messenger, and you end up with three copies of a single file on the disk.
You can use specialized utilities or built-in search to find these objects. In a file explorer, search for the.jpg or.png extension and sort files by size, often helping you find forgotten heavy images in unexpected folders.
And you should also look at the.thumbnails folder, which is a hidden system folder that stores thumbnails of all your photos for quick display in the gallery, and over time, it can be as big as a few gigabytes, it can be safely deleted, the system will create a new one the next time the gallery is launched, but that will temporarily increase the space.
⚠️ Note: The.thumbnails folder is hidden by default. To display it, turn on the "Show Hidden Files" function in the Explorer settings.
Radical measures: Resetting and reflashing
If the software cleanup failed and the memory continues to fill up rapidly on its own, it may have been a file table failure or a virus infection by a miner, in which case a full reset to factory settings helps.
Before the procedure, be sure to back up all important data to the Mi Cloud or your computer. Then go to the Advanced Settings menu → Restore and Reset → Reset. The device will return to the “shop-like” state.
adb shell pm clear com.android.systemuiThis command, which is typed through a computer in USB debugging mode, helps reset the system interface cache if the phone is slow even after cleaning, but it is safer for the average user to use a standard reset via the recovery menu.
💡
Full reset deletes 100% of user data, so backup is a must before the procedure begins.
After reset, take your time to install all the applications at once, install them one by one and monitor the memory behavior, which will help identify the "culprit" who is causing the space leak.
Prevention of memory overflow
To keep the problem from returning in a month, make a habit of checking the storage regularly, run a cache cleanup of heavy apps once a week, turn off auto-save statuses on WhatsApp and auto-upload media to Telegram on mobile networks.
Use cloud services to store archives. Set up automatic photo sync with Google Photos or Yandex.Disk with the function “Free space” will store the originals in the cloud, leaving only compressed copies on the phone or even deleting them locally.
Keep an eye out for MIUI system updates. Xiaomi engineers regularly release patches that optimize the file system and fix errors that cause logs and temporary files to inflate.
