How to Clear Cache on Xiaomi Redmi 8T: The Complete Guide

Xiaomi’s Redmi series smartphones are famous for their performance, but over time, even the fastest processor can slow down due to the accumulation of system debris. Owners of the Redmi 8T model often face a lack of internal memory or lags in the interface, although the device originally had a sufficient supply of power.

Cleaning temporary files is not just a way to free up space, but also a necessary prevention for the stable operation of the Android operating system and the MIUI shell. If you ignore the accumulation of garbage, the phone can spontaneously reboot or open familiar programs for a long time. In this article, we will discuss in detail all available cleaning methods, from standard tools to advanced methods.

You don't need to be a programming expert to do these things. All of the methods below are safe and don't require root rights, which makes them available to anyone, and the key is to follow steps consistently to avoid deleting important personal data like contacts or photos.

Why you need to clean the cache on Redmi 8T

Cache is a temporary file that apps save to make it work faster, like YouTube or Instagram uploading previews of videos and pictures so that they pop up instantly when they reopen, and over time, the database grows to occupy space that could be used to install new games or save documents.

In addition to lack of space, crowded cache can cause conflicts in the operation of programs. Old temporary files can incorrectly interact with new application updates, which leads to departures or freezes. Regular cleaning helps keep RAM in good shape and reduces the load on the processor.

However, it is important to understand the difference between a useful cache and system debris: Cache removal does not erase your logins, passwords or game progress, as opposed to a complete data cleanup. It is a safe procedure that can be carried out regularly without the risk of losing personal information.

⚠️ Note: Deleting the cache of system applications (such as “Themes” or “Security”) may temporarily slow down their first launch, as the system will take time to create new temporary files.

💡

Use the “Accelerate” feature in the standard Safety app at least once a week to automatically clean up surface debris.

Use of the Standard Security Application

The MIUI shell on the Redmi 8T already has a powerful maintenance tool built in. The Security app has a green shield icon, and it's the first place to start servicing your phone, and it scans your device for malware and unnecessary files.

To start cleaning, open the app and click on the Cleanup button. The system will analyze the amount of garbage, including the cache of applications, remnants of remote programs and unused APK installation packages. The scanning process takes only a few seconds thanks to optimization for specific hardware.

After analyzing, you will see a list of file categories that can be deleted. By clicking the Clear button, you will free up space. However, for more in-depth work, it is recommended to go to the extended menu, where you can select specific file types to delete manually.

It's worth noting that a standard cleaner can sometimes be too aggressive or, conversely, lets in hidden debris in messenger folders, so for comprehensive cleaning, it's better to combine this method with manually checking the storage.

Manually cleaning the cache of individual applications

The most effective way to combat memory shortages is to pinpoint the “heavy” applications, where social networks and instant messengers like Telegram, WhatsApp and Viber tend to accumulate gigabytes of media files and temporary data, and they can be managed through system settings.

Go to the Settings menu and select the Apps section, then click All Apps. In the list that opens, find the program you want. Inside the app menu, you are interested in Memory (or Storage), which displays detailed statistics on space usage.

So here you'll see two basic buttons: Clear cache and Clear everything. It's important not to confuse them. The first one deletes only temporary files, the second one completely resets the app to the state immediately after installation, deleting your accounts and correspondence.

⚠️ Warning: The Clear Everything button will remove the authorization in the app. Make sure you remember your login and password before using this feature.

It is recommended to regularly check the cache volume of video services and navigators, as they cache maps and streaming video most actively. On the Redmi 8T with its 64 or 128 GB of memory, this is critically important.

Cleaning through the storage menu

The new Android 9-based MIUI (which is relevant to the Redmi 8T) features a user-friendly memory management menu that allows you to visually assess what exactly is taking up space on your device, accessed through Settings → Memory.

In this section, the system will suggest clearing "Other" or system debris, often hiding the remnants of deleted applications and temporary update files, and clicking on the cleanup button in this menu is safe for user data.

And you can also see a breakdown of file types, images, videos, documents, which helps you to see, for example, that the folder with the downloaded files from the browser has grown to an unimaginable size, even though you didn't even know it.

Using a built-in memory analyzer is the most obvious way to understand the occupancy structure of your drive. Don't ignore the system's recommendations to remove rarely used software.

Cleaning the cache in Recovery mode

For more advanced users, there is a method of cleaning the system cache through Recovery Mode, which is useful if the phone is unstable, the interface is bugged, or there are problems after a system update, and it cleans temporary files of the operating system itself.

To enter this mode, you need to turn off the Redmi 8T 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 continue to keep the volume until the Recovery menu appears.

In a menu controlled by volume buttons (up/down) and power button confirmation, select Wipe Data. In some versions of MIUI Recovery, you need to choose Wipe Cache, but often this feature is combined with data cleaning, so be careful.

⚠️ Note: In the Recovery menu, it is easy to confuse "Wipe Cache" and "Wipe All Data" with "Warning All Data!

If you have a separate Wipe Cache item on your menu, choose it. If you only have Wipe All Data, you should avoid using this method for simple cache cleaning, as it will cause the phone to be completely reset to factory settings.

💡

Recovery is designed to address serious program errors, not regular prevention.

Hidden Opportunities and AdB Team

For those who want to get the most out of it, there are hidden menus and commands. On Redmi 8T, you can activate the developer menu to access the advanced cleaning settings, and you need to quickly click on the build number in the About Phone section 7 times.

After activation in the menu Additional → For developers, you will see the option Reset USB settings or debug over USB. Connecting the phone to your computer and installing ADB (Android Debug Bridge), you can perform cleaning commands remotely.

The command to clean the dalvik cache (system cache of executable files) is as follows:

adb shell pm trim-caches 999999999

This command forcibly removes the cache of all applications, freeing up considerable space, but it is worth using it with caution, since after execution the phone can run slower in the first minutes until it recreates the necessary temporary files.

The command line is a powerful tool in the hands of a skilled user, allowing you to do things that are hidden from the normal interface, but for everyday tasks, the standard methods described above are usually enough.
