How to Clean Cache on Xiaomi Redmi Note 8 Pro

Smartphone Xiaomi Redmi Note 8 Pro was originally positioned as a powerful device with a processor Helio G90T, but even such hardware eventually begins to experience difficulties with the processing of accumulated garbage. MIUI operating system tends to overgrow temporary files that not only occupy precious space in internal memory, but can cause failures in the interface. Users often notice that after six months or a year of active use, the phone begins to slow down when switching between tabs or open long-term “heavy” applications.

Regular cache cleaning is a preventative measure that helps keep the device running at a high level. Cache files are created to make applications load faster, but their excess leads to the opposite effect - the system has to spend resources on indexing and finding the necessary data in the chaos of temporary files. In this article, we will examine all proven methods of cleaning, from standard system tools to deep cleaning through the engineering menu.

It is important to understand that there is a difference between cleaning the cache of a particular application and completely cleaning the system cache. On Xiaomi smartphones with a MIUI shell, a complete cleanup of the system cache through Recovery does not delete user data (photos, contacts), unlike a full reset (Wipe Data). However, before carrying out any manipulations with system partitions, it is always recommended to back up important information to the cloud service or computer.

Cleaning the cache through the standard “Security” application

The easiest and safest way for every Redmi Note 8 Pro owner out of the box is to use a built-in system tool. The MIUI shell is equipped with a powerful optimization module that scans the device for temporary files, remnants of deleted applications and advertising debris. To start the procedure, just look for an icon on the desktop called “Security” (green shield) and start the scan.

Once the analysis is complete, the system will suggest that you delete the files you found, which is ideal for weekly maintenance, as it does not affect important logins and passwords, while maintaining login on social networks and messengers. However, be careful: sometimes the Cleanup section may contain files you planned to save, such as temporary copies of documents from office applications.

💡

Periodically go to the “Clean up” section of the Security app and click on the broom icon at the top to delete files that were skipped during the automatic scan.

It’s worth noting that security algorithms don’t always find deep-seated files in Android/data or Android/obb folders. So if your Xiaomi continues to run slowly even after cleaning, you’ll need to do more in-depth tweaking on the settings of individual programs.

Manually cleaning the cache of individual applications

Often, specific “heavy” applications, such as Telegram, Instagram or TikTok, cause smartphone malfunction, and these programs tend to accumulate gigabytes of media files and temporary data that are not always deleted by standard means. To perform a deep cleaning, you need to go to the device settings menu.

Follow the Settings → Applications → All Apps. In the list that opens, find a problematic app (like a browser or social network) and click on it. In the menu that opens, select Memory, then click Clear and select Clear Cache. This action is safe and will not reset your personal settings inside the app.

In Telegram, for example, cache can grow to 10-15 GB if you do not set limits. Better clean it through the settings of the messenger: Settings → Data and memory → Memory Use → Clear cache. This will free up a significant part of the internal memory of the Redmi Note 8 Pro without losing correspondence.

Using Developer Mode to Clean Dalvik Cache

For more advanced users looking to squeeze the most performance out of their Xiaomi, there is access to hidden system features.Developer Mode allows you to manage the compilation processes of applications and clear the Dalvik/ART rantime cache. This can be useful if after updating the firmware the phone began to work unstable.

To activate this mode, go to Settings → About Phone and quickly click 7 times on the MIUI Version. After the notification “You are a developer” appears, go back to the main settings menu, select “Additional” and find the option “For developers.” There you can find options related to background processes, but be careful: changing the incorrect settings can lead to instability of the system.

⚠️ Warning: Do not disable items related to window animation or limiting background processes if you are not sure of their purpose. MIUI It will get twitchy and notifications will stop coming on time.

The option of forced service shutdown is sometimes found in the same menu, but it is temporary and resets after a reboot. To actually clean the system temporary file mode, use Recovery Mode, which will be discussed below.

Cleaning through Recovery Mode (Recovery Mode)

Recovery mode is a dedicated diagnostic and maintenance environment for the Xiaomi Redmi Note 8 Pro that boots regardless of the main operating system. Here you can perform deep cache cleaning, which is not available in normal operation, this is especially true if the phone is stuck on the logo or running extremely slow.

To enter Recovery mode, turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, after which the phone will go to the Recovery menu. The control here is done with volume buttons (up/down), and the choice is confirmed by the power button.

From the menu, select Wipe Cache Partition. Confirm the action. The system will clear temporary system files. It is important not to confuse this with Wipe Data, which will completely delete all your data. Once you complete the procedure, select Reboot.

Location analysis and garbage disposal

Sometimes the problem is not just the cache, but the forgotten files that the user downloaded months ago. The built-in storage analyzer in MIUI allows you to visualize what exactly is taking up space. Go to Settings → Storage to see the memory distribution diagram.

The system will prompt you to clear the Recycle Bin in the gallery, delete duplicate photos or large video files. Often users forget that deleted photos are stored for another 30 days in the “Recently Deleted” folder, taking up space, and it is also worth checking the Download folder, where APK installation files and documents often accumulate.

Don’t forget to check the folders of streaming services like Spotify or Netflix.If you’ve downloaded music or movies to watch offline and don’t need them anymore, deleting them could free up a few gigabytes of space on your Redmi Note 8 Pro.

Prevention and optimization of MIUI

To keep Xiaomi happy with its speed for as long as possible, it is important not only to clean the cache, but also to properly operate the device.Do not install questionable apps from unknown sources, as they often contain ad modules that generate garbage in the background.

Also, you should limit the background activity of rarely used applications, so in the battery settings, you can set the mode "No restrictions" only for instant messengers, and for other programs, leave standard restrictions, which will prevent them from constantly running in the background and accumulating temporary data.

⚠️ Attention: Installing accelerators and cliners from third-party sources on Android often backfires, consumes resources and displays intrusive advertising. MIUI It is sufficient to maintain the system.

Regularly restarting your smartphone (at least once every 3-4 days) also helps to reset accumulated errors in RAM and complete the hanging processes. This is a simple habit that significantly prolongs the life of the software part of your gadget.

💡

Comprehensive approach: the combination of manual cleaning of heavy applications, the use of built-in analyzer and periodic reboot gives the best result for the speed of Xiaomi.
