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

Redmi smartphones are famous for their performance, but over time, even powerful devices start to work slower. Often the cause of this is accumulated software debris, which takes up precious space in storage. If your Redmi 8 Pro started to slow down, and notifications of memory shortages appear more often, then it’s time to do the general cleaning. In this article, we will discuss all the current methods of cleaning the cache to return the gadget to factory frolic.

Many users confuse cache with important data for fear of losing photos or contacts during cleaning. However, application cache is only temporary files that speed up the launch of programs, but are not critical to their operation. Deleting this data safely and often solves problems with the freeze of the MIUI interface. We will consider both standard system tools and deeper cleaning methods.

Before we get to specifics, it’s worth understanding why memory is overflowing. Apps are constantly storing thumbnails of images, temporal scripts and error logs. Over time, this baggage can grow to gigabytes, which is especially critical for models with a small amount of built-in storage. Regular prevention will help extend the life of your device’s internal memory.

Visual Diagnostics: Analysis of Storage

The first step before any cleaning is to assess the situation. Android provides a convenient tool to see what exactly occupies space. You need to go to the Settings → Memory menu to see detailed statistics. Here you will find that the lion's share is often not your photos at all, but the multimedia from messengers and social media cache.

Note the "Other" section, which may be bloated in the MIUI shell because of system logs and residual files from remote programs. If this is more than 10 GB, standard cleaning may not be enough, and a more thorough approach to folder analysis is recommended, which we will discuss below.

⚠️ Warning: Don’t use third-party accelerators from the Play Market with dubious reputations. They often create unnecessary garbage and display intrusive advertising, instead of actually helping.

To get a good idea of the space, you can use a built-in analyzer to show the top of the heaviest apps, often Telegram, Instagram or TikTok, which is where you start optimizing, because their cache is updated daily and very quickly.

Basic cleaning through the standard Security application

The easiest and safest way to free up space is to use Xiaomi’s regular tool, which is pre-installed on each device and optimized specifically for MIUI. Run it and select “Clean it up.” The system will automatically scan the device for temporary files, advertising debris and unnecessary APK installation packages.

Once scanned, you'll see a list of files you've found, and you'll want to look carefully at the categories "Unused Apps" and "Large Files." Often you'll find old videos you've already sent to the cloud, or game installers you're no longer needed. By clicking the cleanup button, you'll only delete temporary data without affecting your personal information.

It's important to note that an embedded scanner doesn't always find cache inside specific applications, such as browsers or instant messengers. It's focused primarily on system debris and update cache. So it won't be enough to clean this tool deep, but it's perfect for regular maintenance.

💡

Run a standard cleaning once a week to prevent critical memory filling, which is especially important for models with 64GB of built-in storage.

Individual cleaning of the application cache

The greatest effect is manually managing the memory of individual programs. Social networks and instant messengers tend to accumulate gigabytes of data. To clear the cache of a particular application, go to Settings → Applications → All applications. In the list, find the desired program (for example, YouTube or Facebook) and click on it.

In the menu that opens, select Memory. You'll see two buttons: "Clear" and "Delete." It's critical that you don't mix up the actions. The "Clear" button (or "Clear Cache") will only delete temporary files, saving your logins and settings. The "Delete" button (or "Clear All") will reset the application to a state immediately after installation, which will require re-authorization.

Pay special attention to messengers. WhatsApp or Viber has its own storage settings. It is often easier to clear media files through the chat settings by selecting “Clear all messages” with the tick “Delete media files from your phone” that will free up more space than a standard cache clearing through Android settings.

Deep cleaning through the Engineering Menu and ADB

For advanced users who want to make the most of their Redmi 8 Pro, there are more sophisticated methods, one of which is using the ADB command line (Android Debug Bridge), which allows you to remove the cache of system applications that are hidden from the average user, which requires a PC connection and enabled debugging over USB.

adb shell pm trim-caches 999999999

Executing this command will force the cache of all installed applications to a minimum, a powerful tool that can temporarily slow down the launch of programs, as the system will have to recreate temporary files, and use this method only if the standard methods do not work.

⚠️ Attention: Use of teams ADB An error in syntax or the removal of system components can lead to unstable operation of the operating system.

There's also a hidden developer menu available through the code in the call, and entering the ##6484## combination opens up an engineering menu where you can run memory tests, but there's limited direct cleaning functionality, and the main advantage of this method is to diagnose physical memory errors that are software-intensive.

Working with Android folder and system garbage

In modern versions of Android, access to the Android/data folder is limited, but file managers like MIUI Explorer or Total Commander still let you look inside. Inside, you'll find folders of installed games and applications. Often there are files left after you delete programs. Manually delete folders with the names of remote games to make room.

The Thumbnails folder, which is located on the DCIM →.thumbnails path, where you store thumbnails of your photos, and if you delete thousands of photos but your memory doesn't go away, it's probably a bloated folder, and you can delete it safely, and the system will create new thumbnails if you need it.

Remember the Download folder. Browsers and messengers by default save all downloaded files there. Regular sorting of this directory is a habit that saves you from space shortage, PDF-documents APK-file.

💡

Manually checking Download and DCIM/.thumbnails folders often frees up more space than automatic cleaners, as it allows you to delete large files that are forgotten.

Preventing and optimizing the Redmi 8 Pro

To avoid going back to cleaning every month, set your smartphone to work automatically. The Security app has a Memory Acceleration feature that you can add to your desktop. It's also helpful to turn off automatic media storage to the gallery for some instant messengers if you don't plan to store them.

Use cloud storage. Google Photos or Mi Cloud can automatically upload your photos and delete them from your device, leaving only thumbnails. This frees up gigabytes of space without losing access to the archive. On Redmi 8 Pro with its screen, this is especially true for photo enthusiasts.

Update your system regularly. Newer versions of MIUI often improve memory algorithms and fix errors that lead to memory leaks. Go to Settings → About your phone and check for updates. Up-to-date firmware is more stable and manages resources more efficiently.
