Xiaomi Redmi 7, released in 2019, remains a reliable device, but over time owners face a shortage of free space. MIUI operating system accumulates temporary files, and modern applications require more resources, which leads to a slowdown in the interface. Lack of memory is not just an inconvenience, it is a direct way to the fact that the phone will start to “hang” or completely stop running heavy programs.
In this article, we will discuss effective cleaning methods that will help restore the device to its former speed. We will not use questionable cleaners, but we will use built-in system tools and manual configuration. Proper storage will allow you to use Redmi 7 for many years without having to buy a new gadget.
Before we start taking drastic measures, it's important to understand where gigabytes go. Often users don't even realize that instant messengers or social media can take up more space than all the installed games combined. Most storage on Redmi 7 is usually filled with app cache, duplicate photos and forgotten browser downloads. Let's get started.
Analysis of storage occupancy through settings
The first step is always to diagnose. You don't want to delete files at random, hoping for luck. Android provides great tools to visualize what's eating up your space. You first need to go to the settings menu and find the partition that's responsible for the memory of the device.
Click on the Settings icon on your desktop, then scroll down and select About Phone. In the menu that opens, look for Warehouse. Here you will see a color diagram showing the different colors of the data types: apps, images, video, audio, and system files, which gives you a clear idea of which category to work with first.
If apps are the biggest part, you should rethink the installed software list, often with games you haven't played in months or programs for one-off tasks, and removing even one heavy app can free up a few gigabytes, which is critical to the stable performance of Redmi 7.
Notice the "Other" item in the storage list, which is often hidden data, error logs, or remnants of deleted programs. Although the system does not always allow you to delete this with a single click, understanding the volume of "Other" helps you evaluate the effectiveness of further cleaning.
Use of the built-in "Security" application
The MIUI shell on the Xiaomi Redmi 7 has a powerful system tool called Security, which is not just an antivirus, but a whole processor for servicing the device, which includes Cleanup, and it's safer to use than installing third-party software from Google Play.
Launch the Security app (green icon with shield). On the home screen, you will see a Cleanup button showing the amount of garbage that can be removed right now. Click on it. The system will scan and suggest removing temporary files, install package residues and advertising. The system and application cache is the main candidate for removal, since it does not contain important personal data.
But don't just rely on automatic cleaning. Inside the Security app, there's a Deep Clean section, and you can find large files that you might have forgotten, or duplicate images, and be careful when you look at this list, so you don't accidentally delete important documents.
⚠️ Note: When using Deep Clean, carefully check the files in the Download folder. Often, installation files are saved there. APK, which are no longer needed after installation of the program, but take up space.
Regular use of the built-in cleaner, at least once a week, will prevent critical memory filling. This is especially true for models with 32 GB of internal memory, where every megabyte counts. Don't ignore the system's clean-up notifications that appear in the notification curtain.
💡
Set up automatic cleaning in the Security app so that the phone itself clears up debris when the free memory is less than 1 GB.
Clearing the cache and data messengers
The most voracious apps on any smartphone, including Redmi 7, are messengers: WhatsApp, Telegram, Viber. They store every photo, video and voice message received in the memory of the phone. Over time, this collection can grow to 5-10 GB, imperceptibly slowing down the device.
To clean up, you need to go to the settings of the app itself, not the settings of the phone. For example, on Telegram, the path looks like this: Settings → Data and memory → Memory Use. Here you can click Clear Cache. Important: this won't delete your correspondence, the files will just be re-uploaded from the cloud if necessary. On WhatsApp, the path is a little different: Settings → Data and Storage → Storage Management.
In this section of the messenger, you'll see a list of chats sorted by space, and often it turns out that the most space is in group chats, where you're constantly downloading videos, and you can select a specific chat and delete only old media files, leaving the text intact.
- 📱 Open the settings of a specific "heavy" application.
- 💾 Find the "Storage" or "Data" section".
- 🗑️ Click Clear Cache, but not Clear Data (unless you want to reset your account).
- 🎥 In messengers, set up autodelete media files older than 30 days.
The feature called "Autoload Media" deserves special attention, and most messengers have it on by default: turn off the download of videos and photos over the mobile network, and put a restriction or manual confirmation on Wi-Fi, which will save not only memory, but also traffic.
Working with folders and removing duplicates
The Android file system on Xiaomi is organized logically, but requires periodic user intervention. The built-in Explorer (the Explorer or Files application) allows you to manually go through folders and delete what the system considered important, but what you no longer need.
First of all, check the Download folder, which includes all the files from your browser, documents downloaded from email, and pictures from social networks. Often you can find old versions of programs, price lists or presentations that are long gone.
You also have to look at the DCIM folder, which is the.thumbnails subfolder, which is a hidden folder that stores thumbnails of your photos for the gallery, and it can grow to giant sizes, and periodically cleaning this folder through the file manager (pre-enabled the display of hidden files) can free up to 1 GB of space.
How do I find hidden folders?
Don't forget duplicates. When you sync or re-download files, you can create copies of them. Xiaomi's Explorer has a duplicate search function, or you can use size sorting to find the same video files that weigh the most.
Transfer data to memory card and cloud
Xiaomi Redmi 7 supports microSD memory cards, which are the easiest solution to the problem of lack of built-in storage, and can be used as a portable storage for photos, videos and music, freeing up internal memory for the system and applications.
To transfer files, insert the card into the slot (together with the SIM-Then select the files you want in the explorer (for example, all the videos from the Camera folder), click More → Move and choose the path to SD-Modern versions of the map. MIUI It also allows you to transfer some applications to the map, although this feature does not work with all programs.
Cloud services are an alternative to memory cards. Google Photos, Yandex.Disk or Mi Cloud let you store your media library on the Internet. By setting up autosynchronization, you can turn on the "Free Space" feature, which will remove photos from your phone that have already been uploaded to the cloud. This is safe, because copies will remain on the Internet.
| Method | Exclusion | Difficulty | Risk of data loss |
|---|---|---|---|
| Clearing the cache | Low (1-3GB) | Low. | No. |
| Removal of chat rooms | Medium (2-10 GB) | Medium | Medium (requires a backup copy) |
| Transfer to SD | High (up to 128 GB+) | Low. | No. |
| Resetting settings | Maximum | Tall. | Tall (no backup) |
💡
Combining Cloud Storage for Photo and Physical SD-Video cards – the best strategy for owners of Redmi 7 with a small amount of memory.
Radical measures: Resetting to factory settings
If none of the above methods have worked out and the phone continues to run slowly, the last and most effective way is to reset the Xiaomi Redmi 7 back to the state it was when it was purchased from the store.
Before starting the procedure, it is critical to back up all data: Reset will delete everything: contacts, SMS, photos, apps and their settings; use your Google account or built-in Mi Cloud to save important information; make sure that the phone is charged at least 50%.
To perform the reset, go to Settings → About Phone → Reset. Select Erase All Data. The system will ask you to enter the unlock password and password from your Mi Account (if it is enabled). Once confirmed, the phone will restart and begin the cleanup process, which can take 10-15 minutes.
⚠️ Warning: Do not interrupt the reset process or turn off the phone until it is fully loaded. Interrupting system file writing may make it impossible to turn on the device ("brick").
After reset, take your time to install all the applications at once, install only the ones you need and watch the system work. Often it turns out that the problem was in a conflict of some particular application or accumulated system errors that have now been fixed.

Prevention and healthy habits
To keep the question of how to free your memory from coming up every month, you need to develop a few useful habits: Xiaomi Redmi 7 is not the youngest device, and it requires careful attitude to resources. Regularity is the key to success.
First, make it a rule to check the Downloads folder and the gallery basket once a month (the files are stored there for 30 days); second, turn off the autoload of videos on social networks if this is not urgently necessary; third, keep an eye out for system updates - they often provide optimizations of memory.
Use the “light” versions of apps if they are available, such as Facebook Lite or Google Go, which takes up significantly less space and consumes less RAM, which can be a decisive factor for the Redmi 7 performance.
