How to Clean Cache on Xiaomi Redmi 8T

Modern smartphones like the Redmi 8T are slowly slowing down over time, despite the initially powerful Snapdragon 730G processor. The main reason for this behavior is the accumulation of temporary files that the system and applications use to quickly load content, called cache, and it takes up valuable space in the internal memory of the device.

Cache cleaning is not just a way to free up a few gigabytes, but also an effective method of fixing software failures. If the Xiaomi app is not working correctly or freezes, deleting temporary files often solves the problem without the need for complex flashing. It is important to understand the difference between useful user data and junk files that can be safely deleted.

In this article, we will take a look at all the cleaning methods available, from standard MIUI tools to advanced methods through the engineering menu, and learn to distinguish between cache types and when to intervene manually and when to trust automation.

What is cache and why does it accumulate on Redmi 8T

Cache is a clipboard that stores temporary data to speed up programs. When you open a website in a browser or flip through a social network feed, Redmi 8T stores images and scripts in memory. When you re-access these resources, the system loads them faster without consuming mobile traffic or loading the processor.

But over time, the size of these temporary files can become critical, with some apps, especially messengers like Telegram or WhatsApp, able to inflate cache to a few gigabytes, resulting in a lack of space to install new programs and slowing down the overall Android operating system.

• 🚀 Accelerates the launch of frequently used applications due to local storage.
• 📉 Reduces Internet traffic consumption when reloading pages and media.
• 🗑️ It can take up a significant amount of internal memory if not cleaned in time.

Don't be afraid to delete this data, because it's not personal files, your photos, contacts and correspondence will remain in place, but be careful: after cleaning the cache, some applications can load a little longer on the first run until they form a new buffer.

⚠️ Cache clearing does not delete your logins and passwords, but may require re-authorization in some banking applications or social networks for security reasons.

Preparing a smartphone for cleaning temporary files

Before starting active cleaning, you need to conduct minimal preparation of the device, which will help to avoid accidental deletion of important data and ensure the stability of the process. First of all, it is recommended to check the status of the battery, as abrupt power outage during work with system files can lead to errors.

💡

Before a large-scale cleaning, back up your important data in the Mi Cloud or on your computer to protect yourself from accidental loss of information.

It's also worth closing the background apps that aren't currently in use, which will free up RAM and allow system utilities to work more efficiently. On the MIUI-shelled Redmi 8T, this is done by swiping from the bottom up on the multitasking screen or pressing the closing button of all windows.

It’s important to understand that cleaning the cache is a regular maintenance procedure, not a one-off action. For Xiaomi owners with 64 or 128 GB of storage, controlling the storage fill becomes a critical factor in the long life of a smartphone.

Cleaning the cache through the standard Security app

The MIUI shell on the Redmi 8T has a powerful maintenance tool built in. The Security app automatically scans the device for junk files, the easiest and safest way for most users, without requiring deep knowledge.

To start the procedure, look for an icon on your desktop called “Security” or “Security” that looks like a green shield. Launch the app and click on the “Cleaner” button. The system will perform a quick analysis and prompt you to delete files that are not critical to the operation of the OS.

Once scanned, you'll see a list of files you've found, which typically shows remnants of deleted programs, temporary ad files, and cache of system services, and click "Clean" to permanently delete that data, which takes only a few seconds.

• 🛡️ Automatically determines safe to delete system files.
• ⚡ It works quickly and does not require third-party software installation.
• 📊 Detailed statistics of vacated space in megabytes.

⚠️ Attention: There are sometimes promotional offers on the Security app. Be careful not to install recommended games or apps if you don't need them, just close the windows.

It’s worth noting that standard cleaning doesn’t always affect the cache of heavy apps like Instagram or TikTok. These may require a separate approach through the settings of the programs themselves, which we’ll talk about in the next sections. However, for basic maintenance, Xiaomi’s built-in tool is perfect.

💡

The standard Security app only removes system debris and residues, but does not touch the cache of user applications, which requires manually checking the settings of each.

Deep Cache Cleaning of Individual Applications

The majority of temporary data is often generated by user applications, social networks, video services and instant messengers store thousands of images and video files, and to get to them on Redmi 8T, you need to go to the settings menu.

Open Settings and find the Apps section. Select All Applications. Here is the full list of installed software. Find the app that consumes the most memory (usually YouTube, Telegram or browser) and click on it.

In the menu that opens, select the option Storage. You will see two buttons: Clear and Delete. We are interested in the Clean button, which, when you click, will drop the menu with the choice "Clear cache" or "Clear everything." Choose the cache cleaner to avoid losing authorization data.

For some applications, such as Telegram, there is a built-in memory management feature. Once you go into the settings of the messenger itself, you can set a cache limit or clear it completely, including downloaded files. This is often more effective than standard cleaning through Android settings.

Using Developer Mode for Advanced Users

Redmi 8T owners who want to gain maximum control over the system can use the developer menu, which is hidden by default to prevent inexperienced users from changing critical settings, and activating the menu allows you to manage the cache more flexibly.

To turn on the mode, go to Settings → About Phone. Find the MIUI Version string and quickly click on it 7 times in a row. The system will notify you that you have become a developer. Then a new Developer Item will appear in the additional settings menu.

Inside this menu, you can find options related to background processes and memory limits. Although there is no direct button to clear all cache, managing background processes helps prevent them from overgrowth, and there is a feature for forced service stops, which indirectly affects the volume of temporary files.

Be careful when changing the settings in this section. An incorrect configuration can cause the Redmi 8T to start running slower or some features to stop responding.The main purpose here is monitoring, not mass removal.

Clearing the cache through Recovery Mode

The deepest level of cleanup is Wipe Cache Partition via Recovery Mode, which removes temporary files from the operating system itself that are not accessible through the normal interface, which is especially useful after major MIUI updates or in the face of strange system glitches.

To enter this mode, you need to turn off the smartphone 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 button, but continue to keep the volume until the Recovery menu appears.

Navigation in the menu is done with volume buttons (up/down), and the choice is confirmed by the power button. Find Wipe Data, then choose Wipe Cache. It is important not to confuse with Wipe All Data, which will completely delete all your files and reset the phone to factory settings.

• 🔥 Remove system cache accumulated after firmware updates.
• 🔒 Does not affect personal photos, contacts and installed applications.
• ⚙️ Requires accurate execution of instructions to avoid errors.

⚠️ Attention: In new versions MIUI Wipe Cache can be hidden or require you to enter the unlock password. If you are not sure about your actions, you better skip this step.

Once the process is complete, select Reboot. The first run of the system may take longer than usual, as Android will recreate the necessary temporary files, which is the normal system reaction to a deep cleanup.

💡

Recovery mode is a powerful tool for troubleshooting system errors, but it requires caution: choose only Wipe Cache, avoiding Factory Reset.
