Modern smartphones, including the popular Xiaomi Redmi Note 8T, are slowing down over time and the free space in memory disappears for no apparent reason.It is a natural process of accumulating temporary files that create applications and the MIUI operating system itself to speed up access to frequently used data. However, over time, these files can conflict, take up gigabytes of space and cause interface failures.
Cache cleaning is a safe and effective procedure that doesn’t delete your personal photos, contacts or installed apps. Unlike a complete reset, this process only affects temporary clipboards, helping the system to “breathe in” and work more stable. For owners of the Redmi Note 8T, this is especially true, since the model released several years ago requires careful consideration of memory resources.
In this guide, we will take a look at all the cleaning techniques available, from standard system tools to advanced methods through the engineering menu, and you will learn to distinguish between temporary file types and understand when to intervene manually and when to trust automation.
What is cache and why remove it on Android
Cache is a region of RAM or internal memory reserved for temporary data storage. When you run an application, such as a browser or social network, the system stores interface elements, images and scripts there so that when you re-start them, they open instantly. Without the cache, the phone would have to reload the same resources each time, which would significantly increase the load on the processor and battery.
However, uncontrolled cache proliferation has negative consequences: Files can be corrupted, causing errors in the program, or occupy a critical amount, leaving no room for new updates. On the Xiaomi Redmi Note 8T with its internal memory capacity, regular cleaning becomes a necessity to maintain high performance.
It's important to understand the difference between cleaning the cache and cleaning the data. If the first operation just removes temporary debris, the second one completely erases the settings and logins of the application, returning it to the "as after installation" state, so in normal situations, we use the cache cleaning function to avoid losing progress in games or authorization in messengers.

Regularly cleaning the browser cache and heavy apps like Telegram can free up up to 2-3 GB of space on the Redmi Note 8T.
Quick cleaning through the standard “Safety” app
The easiest and safest way to remove temporary files on Xiaomi devices is to use a built-in system tool. MIUI shell is equipped with a powerful optimization module that automatically scans the device for debris. This method is ideal for daily or weekly maintenance of the smartphone without the risk of damaging system files.
To start the procedure, look for an app on your desktop called Security (a shield and lightning icon) and launch it and click on the Clean button. The system will quickly analyze and suggest that you delete the temporary files found, which usually takes no more than a minute and does not require additional actions from the user.
And then there's the application management tools available in the same menu, so you can go to Application Management, select a specific program, and clear the cache if you suspect it's working incorrectly, so you can pinpoint the problem areas without affecting the rest of the system.

Manually clearing the cache of individual applications in settings
Sometimes, automated tools can’t clean deep-seated temporary files, especially in “heavy” applications like YouTube, Instagram or navigators, which require tampering with specific software settings, freeing up a significant amount of space that a standard analyzer might have missed.
To do manual cleaning, go to Settings → Apps → All Apps. In the list that opens, find the program you want (like Google Chrome) and click on it. In the app information window that opens, look for the Memory or Storage section.
There you'll see two buttons: Clear cache and Clear everything. Press the first button. The system will warn you that temporary files will be deleted. Confirm the action. After that, the amount of memory used should be significantly reduced, and the application will start from scratch, re-downloading the necessary resources.
Why can the “Clear Cache” button be inactive?
Use of Recovery Mode for Deep Cleaning
If the smartphone is unstable, freezes or does not boot at all, cleaning the cache through Recovery mode will help.This is a deeper level of interaction with the system, which allows you to delete temporary partition files of the system without affecting the user’s personal data. This procedure is often recommended after major firmware updates. MIUI.
To enter recovery mode on the Redmi Note 8T, you need to turn off the device. Then press the power and volume buttons at the same time. Hold them until the Mi logo appears, then release the power button, while continuing to hold the volume button. When the Recovery menu appears, use the volume buttons for navigation and the power button to confirm the selection.
From the menu, select Wipe Cache, and note that you need to select this item, not Wipe Data, because it will delete all your files. Once confirmed, the system will clean up and prompt you to restart the device (Reboot), which can take several minutes.
⚠️ Note: In the Recovery menu, the volume buttons are the navigation button, and the power button is the choice. Be extremely careful and do not choose Wipe Data / Factory Reset if you do not want to lose all files.
Comparison of cleaning methods: efficiency table
The choice of cleaning method depends on your specific situation: whether you just need to vacate space or need to solve the problem with the hanging. Below is a table that will help determine the best way for the Xiaomi Redmi Note 8T in various use cases.
| Cleaning method | Level of access | Security of data | Efficiency |
|---|---|---|---|
| Security annex | Superficial | 100% securely | Medium (removes obvious debris) |
| Application settings | Medium. | Safe (saves logins) | High (for specific programs) |
| Recovery mode | Systemic | Safe (does not touch photos/contacts) | Maximum (treats system failures) |
| Third-party utilities | Depends on the rights. | Risk of advertising and surveillance | Medium (often duplicated system) |
As you can see from the table, Android and MIUI are the most trusted third-party apps from Google Play often require extra permissions and can become a source of advertising themselves, so using them on the Redmi Note 8T is not strictly necessary.
💡
The combination of manual cleaning of heavy applications and periodic start of the system scanner gives the best result for the stability of the smartphone.
Common mistakes and important warnings
Despite the simplicity of the procedure, users often make mistakes that can lead to data loss or unstable device operation. One of the most common mistakes is the confusion between clearing the cache and completely resetting. Always read carefully which button you press, especially when in recovery mode.
Another mistake is the use of accelerators and cleaners of dubious origin, which often aggressively unload processes from RAM, forcing the system to immediately start them again, which only increases battery consumption. The Redmi Note 8T, with its optimization, is better to rely on built-in memory management mechanisms.
Also worth mentioning is the DNS and browser cache: If the Internet is slow or pages are displayed incorrectly, it makes sense to clear the cache in the browser settings or reset the network settings, rather than clean the entire system all at once.
⚠️ Note: After cleaning the app cache (especially social media and maps), the first run may be slower than usual.This is normal, since the program takes time to re-form temporary files.
⚠️ Warning: Do not interrupt the Recovery cleanup process by turning off your phone or removing the battery.This can damage the file system and require reflashing of the device.
