Xiaomi Redmi and Poco are famous for their functionality, but over time, the MIUI or HyperOS operating system can accumulate temporary files, which leads to slowdowns, lack of internal memory and unexpected program outages. Users often confuse the concepts of cache and data, although technically they are different areas of memory that affect the operation of the device in different ways.
In this article, we will discuss how to properly and safely clean the application data on your device, learn how to distinguish the necessary files from digital garbage and return the phone to its original speed without losing important information. Deep cleaning is not just about deleting, it is about competent management of system resources.
The space-free procedure is one of the most popular among Android gadget owners. Correct cleaning eliminates many software errors that cannot be fixed by a simple restart. Let's take a look at the tools that the Chinese manufacturer provides for this.
Difference between Cache and Application Data
Before you start taking action on the settings menu, you need to be clear about what we're going to delete. Cache is the temporary files that the app creates to quickly load frequently used items, such as pictures in the social network feed or news site headlines, deleting the cache is safe and does not affect your personal settings.
Unlike temporary files, App Data is all the information that makes the program personalized for you, including logins, passwords, game saves, instant messengers, and interface settings, and if you decide to clear that partition, it will return to a “shop-installed” state.
Technical details of data storage
Many users mistakenly believe that cleaning up data will free up more space than deleting cache. In fact, the amount of space taken up may be comparable, but the effects on the user will be radically different. MIUI allows you to manage both types of files separately, which gives you flexibility in maintaining the system.
💡
Cache cleanup is safe and solves freeze issues, while data cleanup completely resets the app to factory settings.
Standard cleaning method through MIUI settings
The most reliable and recommended memory management method is built directly into the Xiaomi shell.It does not require installing third-party software and ensures that system files are not corrupted.
Find the gear icon on your desktop or notification curtain. In the menu that opens, scroll down to the App. In some firmware versions, this section may be called Apps and Notifications or hidden within the All Settings category, and that's where you focus on managing all of your device's software.
After you go to All Apps, you will see a complete list of installed software, sorted by frequency of use or alphabet, and you will see how much space each program takes up and how much memory it consumes in the background.
☑️ Action algorithm on the menu
Select the app you're interested in from the list, and the program card will open, showing you the version, traffic consumption, and space you're taking, and there are two critical buttons, Clear and Delete, and we're interested in the cleaning button, which opens up an additional menu that selects the type of file you're removing.
Step-by-step instructions for deleting files
When you click on the Clean button in the app card, the system will offer two options: the first option is Clear the cache. This operation takes a split second and does not require confirmation. The system silently deletes temporary files, freeing up space on the disk.
The second option is to Clear everything (or Clear Data) and when you select this option, MIUI will issue a warning window requesting confirmation, the system will warn you that all files and settings will be deleted, and this is protection against random user actions, since it will be impossible to restore the data deleted in this way without a backup.
If you clean a messenger like Telegram or WhatsApp, remember that cleaning “everything” will remove your local database of correspondence. You will have to re-enter your phone number and wait for synchronization. So for heavy multimedia applications, it is better to use built-in cleaning tools inside the programs themselves.
💡
For instant messengers, use the built-in cleaning: Go to the settings of the messenger itself → Data and memory → Memory Use. You can delete the cache of channels and groups there without losing your correspondence history.
Once confirmed, the space counter in the app card will decrease, and in some cases, especially for Google or Xiaomi system services, the data volume can quickly recover as applications start to re-download the necessary configuration files.
Use of the built-in "Security" application
Every Redmi and Xiaomi smartphone has a Security system app pre-installed, a powerful combines antivirus, access control and, importantly for us, a memory cleaner. Launch an app with a green shield icon.
On the home screen, you'll see the Cleaner button, and you'll click on it, and the system will scan the device for temporary files, remnants of deleted applications, and large files, and the MIUI algorithm is aggressive enough to find a lot of extra, which is useful for rapid prevention.
However, automatic cleaning is not always deep. It often only affects the surface cache of the system and browsers. For deep cleaning of specific “heavy” applications, such as Instagram or TikTok, it is better to use the manual method described in the previous section, as the machine may be afraid to remove the excess to avoid failures.
The Security app also has a Deep Clean feature that lets you find large files, duplicates and unused apps.It's a great way to free up gigabytes of space that are taken up by forgotten videos or APK installation packages.
Cleaning through Developer Mode and ADB
For advanced users who don’t have enough regular funds, USB debugging is possible, and this method allows you to manage application data via a computer using ADB (Android Debug Bridge) utilities, which is especially useful if the phone’s interface is locked or not working properly.
First, activate Developer Mode. Go to Settings → About Phone and quickly click on MIUI seven times. After the “You’ve Been a Developer” notification appears, go to Additional → For Developers and turn on Debugging by USB.
If you connect your phone to your computer, you can use commands to force the cleanup, for example, a command to clean the data of a particular application is as follows:
adb shell pm clear com.package.nameWhere com.package.name needs to be replaced with the real name of the application package (you can find it in the application card in the settings, scrolling to the bottom), this method deletes data instantly and without unnecessary confirmation on the phone screen, which is convenient for batch processing.
Where can I get the name of the package?
Using ADB gives you rights comparable to root access in terms of process management, but does not require unlocking the bootloader. It is a safe way for experienced users to automate the maintenance process of the device.
Table of the Cleaning Impact on Different Types of Applications
Not all applications respond to data cleansing in the same way. It is important to understand what will happen to a particular type of software after the reset procedure. Below is a table showing the effects of data cleansing on different categories of programs.
| Type of application | What's removed | Do I need authorization? | Risk of data loss |
|---|---|---|---|
| Social media | Cash of pictures, time logs. | Yes, password entry. | Low (if there is a cloud) |
| Offline navigators | Downloaded route maps | No. | High (cards will disappear) |
| Banking applications | Access tokens, cache | Yes, PIN/biometry entry | Medium (must be re-tied) |
| Games (online) | Resources, level cache | Yes, through the account. | Low (Progress in the Cloud) |
| Games (offline) | Continuing progress | No. | Critical (progress will be lost) |
As you can see from the table, the greatest caution should be exercised with cloud-free games and navigation programs, in which case cleaning up the data is equivalent to completely reinstalling the program from scratch.
For banking applications, data cleaning is sometimes the only way to fix the “wrong date” error or connection problems if the system time is knocked down, but then you will have to re-activate the device in the bank application.
Frequent problems and methods of their solution
Users often face a situation where the data clearing button is inactive (gray).This is normal system behavior for mission-critical system applications, the deletion of which can lead to a cyclical restloop. MIUI protects itself from inexperienced actions.
Another common problem is that you can see a rapid growth of space right after cleaning, which is typical of apps like YouTube or browsers, and they immediately start cacheing content, and in these cases, it's not just cleaning it completely, but limiting background activity or setting a cache limit, if that's available in advanced settings.
💡
If the cleaning button is grey, try first pressing Stop on the same menu, which will force the process to close, and the cleaning button should be active.
In rare cases, after cleaning the data of the system application Google Play Store, you may have problems with the download of other programs. If this happens, just reboot the device - the system will automatically restore the basic configuration of services.
💡
If the cleaning button is blocked by the system, do not try to circumvent this limitation without understanding the consequences – it can disrupt the entire operating system.
Prevention of memory overflow
So you don't have to manually clean your data, you have to implement a few smartphone habits, you have to delete unused apps regularly, and even if you don't use them, they can update in the background and grow in size.
Use cloud storage for photos and videos. The built-in Gallery app on Xiaomi can sync media with Google Photos or Mi Cloud. Once successfully synchronized, the Free Place function can be used safely by removing originals from the device.
Also keep an eye out for updates to MIUI itself. Xiaomi engineers are constantly streamlining file system and memory management mechanisms in new firmware versions. Old cache-inducing bugs are often patched with security patches.
⚠️ Warning: Never clean the System Launcher app data unless you can restore the desktop, which will cause all icons and widgets to disappear from the screen, returning it to factory state.
Can I recover deleted application data?
Why does the cache take up a lot of space again after cleaning?
Does the data cleanup affect Xiaomi’s warranty?
⚠️ Note: When cleaning the data of messengers (WhatsApp, Viber, Telegram), be sure to back up the correspondence within the application before the procedure, otherwise the message history will be lost forever.
