How to remove cache on Xiaomi Redmi 6: the full guide

Xiaomi Redmi 6 smartphones, despite their age, remain popular due to their reliability, but over time, the accumulation of temporary files inevitably leads to a slowdown. Users often notice that the device begins to react to touch longer, applications open with a delay, and free space in memory disappears rapidly for no apparent reason. The main culprit of such problems is cache, a hidden area of data storage that is designed to accelerate the launch of programs, but if overgrowth gives the opposite effect.

Cache cleaning is one of the safest and most efficient Android smartphone maintenance procedures, without requiring root rights or deep technical knowledge. Unlike a full factory reset, deleting temporary files does not affect your personal photos, contacts or installed applications. Regularly performing this operation allows you to maintain MIUI in optimal condition and significantly prolongs the comfortable life of the gadget.

In this article, we will take a look at all the cleaning options available, from standard system tools to advanced methods through the engineering menu, which folders can be manually removed and which can not be touched, so as not to disrupt the operating system. Follow the instructions to return your Redmi 6 to its former speed.

What is cache and why should it be cleaned on Redmi 6?

Cache is a buffer memory in which applications store temporary data to quickly access frequently used information. For example, the browser stores copies of visited pages and images so that when you re-enter the site content is loaded instantly, rather than downloaded again. Social networks and messengers also actively use this mechanism, storing media files and contact avatars in the local storage of the device.

The problem arises when the volume of such temporary files becomes too large or when the data in the cache is corrupted. Instead of speeding up work, the system begins to spend resources on finding and processing junk records, which is especially critical for budget models with limited RAM.

⚠️ Cache deletion is safe for personal data, but after this procedure, applications may load a little slower on the first run, as they will have to re-form temporary files.

Regular cleaning helps free up precious gigabytes of internal memory, which is especially true for Redmi 6 versions with 16 or 32 GB of internal storage. Freeing up space allows the system to manage virtual memory more efficiently and reduces the load on the device’s flash memory.

Clearing the application cache through MIUI settings

The easiest and safest way to get rid of the accumulated garbage is to use the built-in MIUI shell tools, which allows you to selectively delete data from specific programs that consume the most resources, and first you need to go to the main settings menu of your smartphone.

Find the Apps or All Apps section, which has a complete list of installed software, and you can sort programs by size of space, which will immediately show the "leaders" in memory consumption, usually social networks, video services and browsers.

Select the app from the list and go to Memory or Storage, and you'll see two main buttons here: Clear cache and Clear everything. The first option deletes only temporary files, leaving your logins and settings, while the second option completely resets the application to its original state.

• 📱 Click on the application icon in the list of installed programs.
• 🗑️ Select the “Clear Cache” option to delete temporary files.
• ✅ Confirm the action in the system pop-up window.

Repeat the procedure for all resource-intensive applications. Please note that the Clean All button also deletes the authorization data, so only use it if the application is not working correctly or you want to completely remove its traces.

Use of the "Safety" application for complex cleaning

Xiaomi's firmware preinstalled the system application Security, which is the primary tool for maintaining the device. It automatically scans the system for malware, but also effectively cleans garbage files. Launch the application through the home screen or tool folder.

Once you scan automatically, the system will suggest that you delete the files you find, click on the Cleanup button or the trash icon, and unlike manually cleaning through settings, this method removes the cache of all applications, as well as the system cache and the remnants of remote programs.

For a deeper cleanup, the Security app has a separate section, often called Deep Cleanup, where you can find large files, duplicate photos, and old APK installation packages that also take up space.

Using a regular cleaner is preferable to installing third-party programs from the Play Market, since it has deep access rights to the system and does not contain advertising. MIUI Do not delete critical files.

• 🛡️ Open the "Security" app on your desktop.
• 🧹 Click on the "Cleaning" button to remove garbage.
• 📂 Go to the Deep Cleanup section to analyze large files.

💡

The regular Security app is the most reliable cleaning tool, as it does not delete system files necessary for MIUI to work smoothly.

Manually delete temporary files through Explorer

For advanced users who want to have full control of the memory contents, manual cleaning is available through built-in Explorer, a method that allows you to find and delete folders that are created by temporary data storage applications but are often forgotten by developers.

At the root of internal memory, look at folders with names of popular applications like VK, Telegram, Skype, and they often contain cache or temp folders that can be safely deleted. Be careful: delete only the files inside these folders, not the system directories themselves.

Special attention should be paid to the Download folder, where forgotten installation files and documents often accumulate, and check the DCIM folder for hidden thumbnails if you do not need them, although this is more a matter of organizing a photo archive.

⚠️ Note: When manually cleaning, never delete folders with Android names, MIUI System or files with the.apk extension, if you are not sure of their origin, as this can lead to unstable operation of the system.

Manual is effective in freeing up a lot of space, but it takes time and care. Before deleting unknown files, it is better to double-check their destination on the Internet or use the "Properties" function to view the path to the file.

• 📁 Open the Explorer and move into the internal memory.
• 🔍 Find folders with app names or the word Cache.
• ❌ Select unnecessary files and click "Delete".

Recovery Mode (Wipe Cache Partition)

The most radical, but also the most effective, method is to clean the system partition of the cache through Recovery Mode, which is especially useful if the phone is unstable, freezes or does not boot correctly after the update, and it cleans the temporary files of the operating system itself without affecting user data.

To enter Recovery mode on Xiaomi Redmi 6, you need to turn the device off 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.

Volume Up + Nutrition = Entry to Recovery

In the Recovery menu, you can control the volume buttons (up/down for moving) and the power button (to confirm your choice). Find the Wipe Data item and select it. In the next menu, you need to choose Wipe Cache, not "Wipe All Data" to avoid losing your files.

Once confirmed, the system will clear the partition. Once the process is complete, select Reboot -> Reboot to System. The first run after such a cleanup may take longer than usual.

• 📴 Turn off the smartphone completely.
• 🔊 Hold the volume up. + Power before vibration.
• 🧹 Choose Wipe Data -> Wipe Cache -> Confirm.

⚠️ Warning: In Recovery mode, carefully check each menu item. Selecting the "Wipe All Data" option will result in the complete removal of all photos, contacts and applications with a return to factory settings.

Comparison of cleaning methods and their effect on the system

Different cleaning methods have different levels of impact on the device and are suitable for different situations. Understanding these differences will help you choose the best way to service your Redmi 6 without the risk of data loss or system disruption.

Below is a table that compares the main characteristics of the methods examined, which will help you quickly navigate which tool to use in a particular case.

For daily use, the Security app is sufficient, which can be run once a week. If you notice that a particular application is slow, use the application settings for point cleaning. Recovery mode is recommended only if there are obvious problems in the system or after major firmware updates.

💡

To automate the process, set up a cleaning scheduler in the Security app so that the phone removes garbage at a given time, such as at night.
