Smartphone owners Redmi Note 10 over time may experience slowdowns in the device, sudden application freezes or lack of free space. This is a natural process of accumulation of temporary files that the operating system MIUI creates to speed up the launch of apps. However, when there are too many of these files, they begin to take up useful space and conflict with new data, causing the interface to malfunction.
Clearing the cache is a safe procedure that does not delete your personal photos, contacts, or installed apps. It is aimed solely at deleting temporary data that can be recreated the next time you launch applications. In this article, we will take a detailed look at how to properly free up memory on your device, using both built-in tools and advanced methods through the engineering menu.
Before taking drastic measures, it is important to understand the difference between the cache of a specific application and the system cache. Application cache stores data for quick access (for example, thumbnails in the gallery or temporary browser files), then as System cache contains logs and temporary files of the shell itself Android. Incorrectly deleting system data may lead to a factory reset, so follow the instructions carefully.
Using the built-in Security application
The easiest and safest way to remove accumulated garbage on Xiaomi Redmi Note 10 —use the preinstalled utility. The company has integrated a powerful optimization tool directly into the system, which eliminates the need for users to download third-party software. This method is ideal for regular maintenance of the device once a week.
First, find an icon on your desktop with the name Securitywhich usually has a green shield as a logo. Launch the application and click on the button Cleaning in the upper left corner of the main screen. The system will automatically scan and show the volume of temporary files that can be deleted without risking personal data.
After the analysis is complete, you will see a list of found files. Click the big green button Cleanto remove garbage. Please note that this section also displays “large files” and “unused applications”, but deleting them requires manual verification so as not to accidentally erase important information.
- 🧹 Regular cleaning through the Security application frees up from 500 MB to 2 GB of space.
- ⚡ The Boost function closes background processes, freeing up RAM.
- 📂 Deep cleaning allows you to find duplicate photos and old screenshots.
⚠️ Attention: Before clicking the “Clear all” button in the “Large files” section, carefully check the list. Sometimes the system marks downloaded documents or archives as garbage that you may still need.
Enable the “Automatic cleaning” function in the “Security” application settings so that the phone itself deletes garbage when you unlock the screen if the volume exceeds a specified limit.
Manually clearing the cache for specific applications
Sometimes a performance problem is not related to the system as a whole, but to one specific application that does not correctly manage its temporary data. Social networks, instant messengers and browsers often grow to gigantic proportions, occupying gigabytes of memory. In such cases, spot cleaning through settings Android will be the most effective solution.
To perform this operation, go to the menu Settings of your smartphone. Scroll down the list and select Applications, and then click on All applications. Here you will see a complete list of installed software. For convenience, you can sort the list by size by clicking on the sort icon to immediately find the most “heavy” apps.
Select the problematic application from the list, for example, Telegram or Chrome. In the menu that opens, find the section Memory or Storage. You will see two buttons: “Clear cache” and “Clear all”. Click only the first button Clear cacheif you do not want to reset login settings and delete saved app data.
| Application type | Average cache size | Clearing frequency | Risk of data loss |
|---|---|---|---|
| Browsers (Chrome) | 200–800 MB | Once every week | Low (history only) |
| Social networks (Instagram) | 500 MB - 2 GB | Once a month | Low (password required) |
| Messengers (Viber) | 1–5 GB | As needed | Medium (media files) |
| Games (PUBG) | 2–10 GB | Rarely | High (game resources) |
After clearing the cache, the application may start a little slower the first time, since it will have to reload the necessary resources from the network or memory. This is normal behavior and will quickly become normalized. If you click “Clear all”, the app will return to the state immediately after installation, which will require re-authorization.
Clearing the system cache via Recovery Mode
If the phone is unstable even after clearing applications, the problem may lie in system partition. To solve this problem, the recovery mode is used Recovery Mode. This method allows you to delete temporary files of the operating system itself without affecting the user's personal data if everything is done correctly.
First you need to completely turn off the smartphone Redmi Note 10. Make sure the device is at least 50% charged to avoid power outage during the procedure. Then hold down the Volume Up button and the Power button at the same time. Hold them until the logo Miappears on the screen, then release the power button, but continue to hold the volume.
You will be taken to the main menu Recovery. Control here is carried out using the volume buttons (up and down) and the power button (confirmation). Select a language Englishif it is not installed by default. Next, find the item Wipe Data and confirm the action. In the next menu, it is critical to select the option Wipe Cacheand NOT Wipe All Data.
⚠️ Attention: Selecting the “Wipe All Data” option will completely reset the phone to factory settings, deleting all your photos and contacts. Be extremely careful and select only “Wipe Cache”.
After completing the cleaning process, the system will prompt you to return to the main menu (Back to Main Menu) or reboot the device (Reboot). Select reboot to normal system (Reboot to System). The first startup after such a procedure may take longer than usual - this is normal, since the system rebuilds temporary files.
☑️ Preparing to enter Recovery
Deleting the cache via a computer (ADB)
For advanced users who prefer full control over the device, there is a method for clearing the cache using a computer and utilities ADB (Android Debug Bridge). This method allows you to delete even those system logs that are not accessible through the standard settings menu or Recovery.
First you need to enable USB debugging mode on your smartphone. To do this, go to Settings → About phone and quickly click on the item MIUI version seven times until the message “You have become a developer” appears. Then return to the settings menu, find the section Advanced → For developers and activate the switch USB debugging.
Connect Redmi Note 10 to the computer via the original cable. Open the command line on your PC in the folder with installed ADB tools and enter the command to test the connection:
adb devicesA request for debugging permission will appear on the phone screen - confirm it. After a successful connection, enter the command to clear the cache partition:
adb shell pm trim-caches 999999999This command instructs the system to trim the application cache to the minimum possible size. Alternatively, if you have superuser rights (Root), you can use more powerful commands, but for a regular user the option is with trim-caches is the safest and most effective.
What to do if the computer does not see the phone?
Install ADB Interface drivers from the official Xiaomi website or use universal Google USB drivers. Also try replacing the USB cable, as some cables only support charging, but not data transfer.
Clearing the DNS cache and network traffic
Often users complain about slow loading pages or problems connecting to Wi-Fi, not realizing that the reason may lie in a clogged network cache. Devices Androidincluding Redmi Note 10have a DNS query caching mechanism that speeds up reconnection to sites, but can become outdated over time.
There is no special button in the menu to clear this type of cache, but you can use Airplane mode. Turn it on Airplane mode for 10-15 seconds, and then turn it off. This action forces all network connections to be reset and clears temporary network buffers. A deeper reset can be performed through the network settings menu.
Go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth. Click the button Reset settings at the bottom of the screen. The system will warn you that all saved Wi-Fi passwords and Bluetooth pairing settings will be deleted. Confirm the action to clear the device's network stack.
- 🌐 Reset settings network solves problems with the “freezing” of the Internet.
- 🔑 After resetting, you will need to re-enter passwords for home Wi-Fi networks.
- 📱 The settings of the mobile access point will also return to the factory values.
⚠️ Attention: The settings menu interface may differ slightly in depending on the MIUI firmware version (12, 13, 14). If you do not find the “Reset settings” item in the specified path, use the search in the settings for the request “Reset.”
Prevention and maintenance of system cleanliness
In order not to return to the issue of clearing the cache too often, it is worth introducing a few simple habits of using your smartphone. Automation of processes and careful attention to installed apps will help keep Redmi Note 10 in excellent condition for a long time.
Try not to install applications from unverified sources. Third-party apps often contain adware modules that generate a huge number of junk files in the background. Use only the official store Google Play or a verified catalog GetApps from Xiaomi.
Check the “Downloads” folder regularly. Many users forget that downloaded APK installation files, documents and pictures remain in memory forever, even if the app is already installed or the document is no longer needed. Delete these files manually once a month.
The best optimization strategy is not a one-time general cleaning, but a weekly light cleaning through the built-in Security application combined with manual deletion of large unnecessary files.
Remember that memory fullness affects the speed of the flash drive. When free space is less than 10% of the total volume, the system begins to work slower due to the nature of data recording. Try to keep at least 3-5 GB of space free for comfortable operation of the operating system.
Frequently asked questions (FAQ)
Will my WhatsApp correspondence be deleted when clearing the cache?
No, when you use the “Clear cache” button in the application settings, your messages, media files and history correspondence will be saved. Only temporary files that speed up startup will be deleted. However, if you click “Clear All Data”, the correspondence will be deleted if there is no backup.
How often should you clear the cache on Redmi Note 10?
For an ordinary user, it is enough to clear it through the “Security” application once every 1-2 weeks. It is recommended to deep clear the system cache via Recovery only if serious performance problems occur or after major system updates, approximately once every 3-6 months.
Why is the space not freed up after clearing the cache?
You may have cleared only the application cache, but did not delete “junk” files, such as old updates, duplicate photos or files from Download folders. Also, some applications (for example, instant messengers) store media files not in the cache, but in the main data folder, which needs to be cleaned through the built-in file manager.
Can clearing the cache harm the phone?
No, the procedure itself is safe. The only temporary effect is that applications may start a little slower the first time after cleaning because they need to re-create temporary files. There will be no physical harm to the device or loss of personal data (if you select the right options).
What to do if the phone freezes after clearing the cache?
If the device freezes, try performing a forced reboot by holding the power button for 10-15 seconds. If the problem persists, the system file may have been damaged and will require a factory reset or flashing the device via a computer.
