Xiaomi and Redmi smartphones are famous for their performance, but over time, even a powerful device begins to work slower. One of the main reasons for the slowdown of the interface and the appearance of errors is the accumulation of temporary files and debris in the memory of installed programs. Understanding how to clean the data of applications on the android xiomy Redmi becomes a critical skill for any owner who wants to extend the life of a gadget without buying a new one.
Android is designed to store information for fast downloads, but often these files are inflated to giant sizes. Owners of budget models with 64 or 128 gigabytes of internal memory face space shortage more often than others. Regular storage maintenance allows not only to free up space for photos and videos, but also to eliminate bugs when the application stops opening or freezes.
In this article, we will explore the difference between cache clearing and full data reset, and the hidden features of MIUI and HyperOS. You will learn how to safely remove excess without losing important correspondence or progress in games. A competent approach to memory management will turn your phone into a fast tool ready for any task.
Difference Between Cache and Data: What to Delete Safely
Before we move on to action, we need to understand the architectural differences in the storage of information on Xiaomi smartphones. Cache are temporary files that the application creates to speed up its work, such as previews of images in the social network feed or boot scripts of the game.
On the other hand, these apps are your personal information: settings, logins, saved passwords, game progress and instant messenger databases. If you decide to clean the data, the program will return to the "just installed" state and you will have to configure it again. Deleting the instant messenger data without prior backup will lead to irretrievable loss of correspondence history.
The Android shell system MIUI clearly defines these concepts in the memory management menu. It is important for the user not to confuse the "Clear Cache" button with the "Erase Data" button, especially if you want to just free a couple of gigabytes, rather than delete an account.
⚠️ Before clicking the “Erase All Data” button, make sure you have an up-to-date backup of important information in the cloud or on your computer.
In most cases, cleaning the cache is enough to speed up the work, which does not require rebooting the device and takes seconds, but if the application does not work correctly even after cleaning temporary files, then resort to more radical measures.
Standard cleaning through smartphone settings
The most reliable and controlled way to get your system in order is to use the built-in settings menu, which is available on all firmware versions, from the old MIUI 11 to the latest HyperOS. To get to the menu, go to Settings → Applications → All applications. Here is the full list of installed software.
Select the program you are interested in from the list. On the screen that opens, you will see the memory button or options immediately. The system will show how much space the application takes up, and how much is allocated for user data and cache. To quickly clear temporary files, just click the corresponding button at the bottom of the screen.
☑️ Checking before cleaning
If you want to remove all traces of program usage, including authorization, select the option "Clean" or "Erase data". The system will request confirmation of the action, as this is an irreversible process for the current session, and then the application will run as the first after installation from the store.
- 📱 Open the settings and find the application management section.
- 🔍 Choose the program that takes up the most space.
- 🗑️ Click "Clean Cache" for Safe Garbage Removal.
- ⚙️ Use "Erase Data" only to completely reset the program.
This method is ideal for spot work with specific heavyweights, such as navigators or video editors, it does not require an Internet connection and even works in safe mode.
Use of the built-in "Security" application
Each Xiaomi and Redmi smartphone has a Safety system app pre-installed with a green shield icon, a powerful maintenance harvester that can automatically find and delete temporary files, launch the app and click on the big Cleanup button, and the system will scan the device and suggest that you remove the garbage.
The functionality of the cleaner is deeper than it seems, and after the initial scan, you can click on the "Clean up garbage" button, then go to the "Applications" section, and here the system will show the top programs that consume memory, and suggest clearing their cache (in one click), which saves time, because you don't have to go through each application manually.
💡
Set up automatic cleaning in the Security app so that the phone removes garbage once a week without you.
Importantly, the built-in cleaner is sometimes too aggressive or misses some files, and it does a great job of handling system debris and browser cache, but it may not affect the folders with media files in messengers, so use it as the first stage of maintenance, followed by manual verification.
⚠️ Note: Carefully check what is ticked before cleaning so you don’t accidentally delete uploaded files from WhatsApp or Telegram if you need them.
Regular use of this tool helps keep the system in good shape, and it is especially useful to start cleaning after installing a large number of new programs or after updating the system.
Deep cleaning of WhatsApp and Telegram messengers
Messengers are the main memory eaters on any modern smartphone, and they store every photo, video and voice message sent to the device’s memory, which can be controlled through the built-in file manager or the settings of the apps themselves.
On WhatsApp, the cleanup is done through the app's menu. Go to Settings → Data and Storage → Storage Management. The system will show files that are more than 5 MB long and allow you to select chat rooms to clean up. Deleting media files from the chat will not delete text messages, which is very convenient.
Telegram is even easier with the cloud architecture. Select Data and Memory in your settings → Memory Use → Clear cache. Since all messages are stored on the server, you can safely delete the cache, it will only do it again when you open the old chats. This is the most efficient way to free up gigabytes of space.
- 💬 On WhatsApp, use built-in storage management to sort by size.
- ☁️ Telegram cache can be cleaned regularly, data will not be lost.
- 🎞️ Delete automatically downloaded videos in your privacy settings.
- 📂 Periodically check the download folder for duplicates.
Remember to turn off auto-save to the group chat gallery, where postcards and videos are constantly dropped, which will save your gallery from chaos and save space.
Memory analysis and data type table
It's helpful for advanced users to understand what types of data are taking up space. Android categorizes application files into several categories, and understanding this structure helps make informed decisions about what to delete and what not to touch.
Below is a table showing the impact of different types of cleaning on the state of the application and user data, which will help you not get confused in terms.
| Type of cleaning | What's removed | Is login to the account maintained? | Influence on the spot |
|---|---|---|---|
| Clearing the cache | Temporary files, previews | Yes. | Minimum |
| Clearing the data | All files, settings, bases | No. | Maximum. |
| Deletion of the annex | The program and all its files | No. | Complete. |
| Resetting settings | The entire system and user data | No. | Critical |
As you can see from the table, cache cleaning is a safe routine, whereas data cleaning is a heavy artillery. Use that knowledge to precisely manage your Redmi or Poco resources.
Delete residual files and work with the Android folder
When you delete applications, you often have tails, empty folders or forgotten configuration files, and Xiaomi's built-in Explorer app is convenient for dealing with them on smartphones. Go to the Folders section and look at the Android/data directory.
Newer versions of Android have limited access to this folder, but Xiaomi's file manager usually asks for special permission to work with it, it stores game and heavy app data, and you need to delete the contents of folders with caution: if you delete the game folder, progress may disappear (if there is no cloud storage).
Should I delete the folder.thumbnails?
It's also worth checking the root folders with the names of applications that have been deleted for a long time, and users often forget that after uninstallation of the program, its folder with its logo or temporary files remains dead weight.
⚠️ Note: Do not delete system folders with names like com.android.systemui or com.google.android.gms, this will lead to unstable smartphone operation.
Regularly auditing the file system once a month will help keep things in order, especially for models with little internal storage.
Radical measures: resetting and optimizing the system
If cleaning these apps didn't help and the phone continues to slow down, maybe the problem is deeper. There's a "Memory Extension" feature in the MIUI system that uses a portion of the internal storage as RAM. Make sure it's enabled in the settings Additional → Expansion of Memory if you don't have enough RAM.
In the extreme case, when software errors accumulate critically, a complete factory reset helps. This will delete all data from the phone. Before you do this, make sure to back up via Mi Cloud or on your computer. The path to reset: Settings → About phone → Reset → Erase all data.
💡
A full reset returns the phone to the speed of the new device, but takes time to restore settings and applications.
After a reset, don't rush to install hundreds of applications at once, just put in what you need and watch the system work. Often the cause of problems is one particular conflict software that you didn't know before.
- 🔄 Use the memory expansion function to improve multitasking.
- 💾 Backup before any radical interference with the system.
- 🧹 Remove unused apps right away, don’t store them just in case".
- 🚀 Reboot your smartphone at least once a week to reset processes.
A comprehensive approach to cleaning up your application data and the system as a whole will ensure your Xiaomi lives a long and fast life. Don’t be afraid to experiment with settings, remembering the importance of backups.
