How to clear the browser cache on the Xiaomi Redmi phone

Modern Xiaomi and Redmi smartphones, which are powered by MIUI shells or the new HyperOS, have powerful hardware, but over time, even flagship models can slow down. The main reason for the decline in performance and lack of space is often the accumulated cache of applications and system services. These are temporary files that are created to speed up the load of often used data, but over time grow to gigabytes, occupying precious space.

Many users confuse cache cleaning with completely deleting apps or resetting settings, which is completely wrong.Cache cleaning is a safe procedure that does not delete your personal photos, contacts or logins in your accounts.It only erases temporary garbage that the system no longer uses or was created with errors. Regular maintenance of storage avoids sudden freezes and problems with launching programs.

In this article, we will take a closer look at all the memory freeing options available on Xiaomi devices, learn how to use the built-in system tools, how to clean the cache of individual programs and browsers, and apply advanced methods for power users. Understanding the structure of Android files will help you keep your phone in perfect condition without the need to install third-party software.

What is cache and why it should be cleaned on MIUI

Cache is a buffer memory where apps store temporary data for quick access. For example, when you browse through a social network, Android saves thumbnails of images and parts of pages so that when you reopen them, they load instantly, but over time, this data can become outdated, conflict with new versions of programs, or simply take up space if the application stops using them.

The main problem is that many Xiaomi programs don’t know how to manage their cache properly, and they keep accumulating files even if they are no longer needed, which leads to a rapid decrease in disk space and the system starts to run slower due to data fragmentation and constant access to overcrowded storage.

There is a myth that constantly cleaning the cache harms the battery or the processor. In fact, good file system maintenance prolongs the life of the drive, as it reduces the number of rewriting cycles in crowded sectors, the main thing is to do this consciously using the right tools, rather than manually deleting system files.

Use of the built-in "Security" application

The easiest and most reliable way to clear the cache on Xiaomi Redmi is to use the regular Security app, which is preinstalled on the system. It is designed specifically for the MIUI shell and has access to system partitions that third-party programs cannot penetrate without root rights.

To get started, you need to start the app and select the Cleanup function, and the system will automatically analyze the storage and find files that can be deleted without harming the phone, and the scanning process usually takes 10 to 30 seconds depending on the amount of information accumulated.

Once you have finished the analysis, you will see a list of categories of garbage, including the system cache, application cache and remnants of remote programs. Attention: before pressing the cleanup button, you can see in detail what exactly will be deleted so that important temporary files, such as drafts in messengers, are not accidentally lost.

⚠️ Warning: Don't use third-party "accelerators" from the Play Market if you have Xiaomi built-in tools MIUI work more efficiently and do not waste the battery, working in the background.

Clearing the cache of individual applications through settings

Sometimes you need to clear the cache of just one particular application that is not working properly or takes up too much space. Unlike global cleaning, this method allows you to pinpoint the problem program without affecting the rest of the system data, this is especially true for “heavy” applications like Instagram, TikTok or navigators.

To do this, go to Settings → Applications → All Apps. Find the program you want in the list that opens. Note that depending on the version of MIUI, the order of items may vary slightly, but the logic remains the same for all Redmi models.

Inside the app menu, you'll see a memory or storage button, and you'll click on it and you'll get access to detailed statistics, and there's two basic functions available: Clear cache and Clear everything (or Reset), the first one only deletes temporary files, the second one returns the app to state immediately after installation.

💡

If the application freezes or crashes immediately after launch, try clearing the cache first, and if it doesn’t help, perform a full application data reset.

Special attention should be paid to messengers such as Telegram or Viber, which cache all the photos and videos viewed, and their settings often have their own built-in cache cleaning function, which works even more efficiently than the system, since it allows you to choose the period of storage of media files.

How to clear the browser cache on Xiaomi Redmi

Browsers are among the main users of temporary memory, and when surfing the Internet, cookies, scripts and images are stored, which speeds up the loading of pages when you visit again, but the accumulation of this data can lead to errors in the display of sites and take up a significant amount of memory.

To clean up a standard Mi Browser or Chrome browser, you need to open the browser's settings, which are usually in a three-dot or bar menu. Select History or Privacy, then click Clear Data. Here you can choose whether to delete your browsing history, cookies or cached images.

It's important to understand the difference between deleting a history and clearing a cache. History is a list of sites you've visited, and cache is files that you download from those sites. If you want sites to reopen with relevant content, just clear the cache.

Once the browser cache is cleared, pages can load a little slower when they first start, as the system will have to re-download all the design elements of the sites, a normal behavior that quickly normalizes.

Extended cleaning through engineering menu and ADB

For advanced users who want to get the most out of it, there are deeper cleaning methods, and they need to be careful because they affect system partitions, and one of those is using ADB (Android Debug Bridge) commands over a computer.

To do this, you need to enable debugging via USB in the “Developers” menu (to activate this menu, you need to quickly click on the build number in the “About Phone” section 7 times). By connecting the phone to the PC, you can execute a command to clean the Dalvik cache, which is responsible for the operation of the Android virtual machine.

adb shell pm trim-caches 999999999

This command forcibly frees up space by removing the cache of all applications, even those that the system normally preserves, and use this method only if you understand what you're doing and you have a backup of important data.

💡

Use of the ADB-commands give maximum effect, but requires a computer and basic knowledge of working with the command line.

⚠️ Warning: Never delete files from system folders manually through a file manager unless you know their exact purpose.This can lead to a phone bootloop (cyclical reboot.

Automation and prevention of memory overflow

To avoid manually cleaning every time memory runs out, you can set up automatic scripts. The Security app on Xiaomi has a Speed Up feature that you can set to automatically start when you reach a certain memory filling threshold.

You should also pay attention to the settings of the apps themselves, for example, on YouTube you can limit the size of the cache, and in messengers you can set up automatic deletion of media files over a certain period of time, which will prevent the growth of “junk” in the future.

Regularly restarting your smartphone is another simple but effective prevention method: When you turn off and on the device, many processes are completed, and temporary RAM files are cleared, which has a beneficial effect on overall system performance.
