Xiaomi’s Redmi line of smartphones is famous for their performance, but even the powerful hardware eventually begins to experience a shortage of resources. Redmi Note 7, released as a bestseller in the middle segment, can slow down over time due to the accumulation of temporary files. This data is created by applications to speed up access to frequently used information, but their excess leads to overflow of internal memory.
Users often notice that the interface is becoming less responsive and apps are opening longer than usual. It's a sure sign that it's time to clean up the system. Regularly cleaning the cache helps free up precious gigabytes and return the device to its previous speed without having to buy a new phone.
In this article, we will take a look at all the available methods for deleting temporary files, learn how to safely clean a system without deleting important data such as passwords or correspondence, and consider both standard MIUI shell tools and deeper cleaning methods.
Why you should delete temporary files on Redmi Note 7
Cache is a memory buffer where data is stored that can be quickly requested by the processor. For example, when you open Instagram or YouTube, some of the images and video files are stored locally. When you re-enter, the app downloads them from the disk, not from the Internet, which saves traffic and time. However, over time, the volume of such "workpieces" can reach several gigabytes.
The problem is that old files can conflict with new versions of applications, which often leads to bugs in the software, to spontaneous closure of programs, or to freeze the interface, and clearing the cache eliminates these conflicts by forcing applications to download the relevant data again.
⚠️ Attention: It is important to distinguish between cache cleaning and data cleanup. Deleting data will reset the application to the state immediately after installation, destroying your logins, settings and saves inside the program.
In addition, a crowded system partition can slow down the entire Android operating system. When the space runs out, the system has nowhere to create new temporary files for current tasks.
Cleaning the cache through the standard Security app
The easiest and safest way to free up space is to use a built-in tool from Xiaomi.The MIUI shell comes pre-installed with the Safety app, which has a green zipper icon. This tool automatically scans the system for junk files.
To start the procedure, launch the application and click on the large Cleanup button, the system will analyze and show the amount of files that can be deleted without harming the device, usually including temporary installation files, remnants of remote programs and advertising debris.
- 📱 Click on the desktop security application icon.
- 🧹 Wait for the automatic scanning of the system to be completed.
- ✅ Click the Clean button to remove the debris found.
- 🔄 If necessary, run a re-scan to look for hidden residues.
Once you've completed the process, you'll see a report on how much space has been vacated, which is ideal for regular maintenance, because it eliminates the risk of deleting important user information, and the system determines which files are safe to delete.
💡
Do a quick cleaning through the Safety app once a week to keep the system on track and prevent large amounts of debris from accumulating.
Removing the cache of individual applications in the settings
Sometimes you need a spot cleaning when a particular application is not working properly or taking up too much space. In Redmi Note 7, you can go into the settings of each programu you install and clear its cache individually, a deeper method than using a standard utility.
Go to the Settings menu, then select the App and then All Apps. In the list that opens, look for a problem program like Telegram or Chrome. Inside the app menu, you'll see a Clean or Storage button.
| Type of data | What's removed | Secure for the account. |
|---|---|---|
| Cash. | Temporary files, thumbnails, auto-saves | Yes. |
| Data data | Logins, passwords, settings, correspondence | No. |
| Memory. | Amount of cache and application data | Depends on choice. |
When you click on the clean button, the system will warn you of the consequences. If you choose Clear Cache, your logins will remain in place. If you choose Clear All Data, you will have to reconfigure the application. Be careful when choosing the action so that you do not lose access to important services.
☑️ Check before cleaning the application
Cleaning the system cache through Recovery Mode
If the smartphone is unstable, glitchy or not loading correctly, you may need to clean the system partition cache (Dalvik/ART Cache), this is done through Recovery mode.
To enter this mode, you need to turn off the phone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power, but keep the volume up until the Recovery menu appears.
Navigation in this menu is done by volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item (in some versions of MIUI it may be called differently or hidden in the submenu), but be extremely careful: look for the option Wipe Cache, not Wipe All Data.
⚠️ Attention: In new versions MIUI On Redmi Note 7, the cache-only cleanup in Recovery may be missing or replaced with a full reset. If you only see "Wipe All Data", it is better not to risk losing information.
This is considered a "heavy artillery" and is used in case of serious malfunctions in the operating system. If the phone is working normally, but just lacking space, it is better to use software methods of cleaning through the settings.

Using third-party utilities for deep cleaning
Standard tools are not always enough, especially if you actively use a lot of social networks and instant messengers. Third-party applications such as Files by Google, SD Maid or CCleaner can find remnants of remote programs and empty folders that the system ignores.
Install the app you select from Google Play and give it the permissions you need, and most of these tools will offer you to do some intelligent analysis, and they will show you duplicate photos, old screenshots, and APK files that you left after you installed the software.
- 🗑️ Removal of residual files after uninstallation of programs.
- 📸 Search and remove blurred or similar photos.
- 📦 Analysis of folder size to identify "eaters" of the place.
- 🚀 Optimizing RAM to Accelerate Current Tasks.
But remember, these apps consume resources themselves, and don't keep them running in the background all the time, but use them as needed to do the clean-up of the Redmi Note 7.
Clearing the cache in the browser and messengers
Browser and messengers deserve special attention, as they accumulate the most garbage. In Chrome, Yandex.Browser or UC Browser, the cache can take up hundreds of megabytes. You can clean it through the browser settings in the "History" or "Privacy" section.
In messengers like Telegram and WhatsApp, the situation is even more serious: these apps store all the photos and videos you've viewed in your phone's memory. Telegram's settings have a special section called Data and Memory -> Memory Use, where you can clear the cache with a single click without losing correspondence.
Set a limit, for example, so that WhatsApp doesn’t save the photos to the phone gallery, but only keeps them inside the app, which will save much space in the internal memory of the Redmi Note 7.
💡
Messengers and browsers are the main sources of garbage, and cleaning these applications regularly gives the greatest increase in free space.
Preventing and optimizing Xiaomi memory
To avoid running out of space too often, you should stick to simple rules of operation: Don't fill your internal memory to the fullest. Android requires about 10-15% of the free space for the correct operation of the mechanisms of writing and reading data.
Use cloud storage for photos and videos. Services like Google Photos or Yandex.Disk can automatically upload media files to the cloud and delete them from the device, freeing up gigabytes of space, which is especially true for models without a memory card slot, although it is present in the Redmi Note 7.
Check the Download folder regularly, and often it accumulates installation files, documents, and pictures that you no longer need, and deleting them is the fastest way to get free space right now.
⚠️ Warning: Don’t install questionable accelerator apps from unverified sources, often as sources of ads and viruses that slow down your Xiaomi even more.
Following these simple guidelines will keep your Redmi Note 7 fast and responsive for a long time.Remember that digital hygiene is just as important as hardware care.
