How to Clear Cache on Xiaomi Redmi Note 4: A Complete Guide to Acceleration

The Xiaomi Redmi Note 4, despite its age, is still a popular device due to its good price-performance ratio. However, over time, the MIUI operating system has become increasingly rich in temporary files that take up precious space and can slow down the interface. Clearing the cache is the first step that a user needs to take when they notice a slowdown or a lack of internal memory.

The process of freeing up memory does not require root rights or deep technical knowledge. Xiaomi’s shell has powerful maintenance tools that are available to every owner. In this article, we will examine all available methods, from quick cleaning through a standard application to deeper methods of removing system debris.

Regular maintenance of the gadget prolongs its life and ensures stability. On the Redmi Note 4 with a Snapdragon 625 processor, the accumulation of errors in the cache can cause a spontaneous reboot of the system. So it is important to understand the difference between application data and temporary files so that important information is not accidentally deleted.

What is cache and why delete it on Redmi Note 4

Cache memory is a buffer section that stores temporary files necessary to quickly load frequently used applications and web pages. When you open a browser or social network, the device stores some of the data locally so that the next run does not waste traffic and time on rebooting. Over time, this data can reach several gigabytes.

Cache deletion does not result in loss of personal data such as contacts, photos or instant messenger correspondence. This is a secure procedure that only deletes temporary logs, thumbnails of images and remnants of deleted programs. However, you should be careful when using third-party software-cliners that can aggressively delete the necessary system files.

The main signs that it’s time to clean the Redmi Note 4 are:

• 🐌 Noticeable slowdown in opening applications and switching between desktops.
• 📉 Reduce the amount of free internal memory without installing new programs.
• 🔄 Frequent interface freezes or unexpected application closures.

Android itself can manage memory, but with a limited 32GB or 64GB storage, manual control becomes a necessity, especially for users who are heavily using multimedia and heavy gaming.

Use of the built-in "Security" application

The easiest and safest way to clean up is to use a standard tool from Xiaomi. Security is already preinstalled on the system and has access to all the necessary parts of the file system. To get started, find a green shield icon on your desktop and run it.

Once you start, the system will automatically scan, you need to click on the Cleaner button located at the top of the menu, the scanner will analyze the files and suggest removing the garbage. It is important to look carefully at the list before confirming, since the default can be selected gallery or browser caches where important form data is stored.

💡

Use the Speed Up function in the same app Security immediately after cleaning the cache – this will force the background processes to close and free up RAM (RAM).

For more details, go to Clean Up -> Deep Cleanup. Here you will see a breakdown by category: large files, rarely used apps, APK installation packages. Deleting APK installers is safe if you have already installed the appropriate programs.

You can set up automatic cleaning in this section, and it will offer to remove the garbage when the amount of free memory drops below the critical level, which is a useful feature for forgetful users, but it does not replace manual checks once a month.

Manually cleaning the cache of specific applications

If the memory problem is related to one particular application, such as Telegram or YouTube, there is no point in cleaning the entire phone. MIUI has a convenient mechanism for managing the memory of individual programs. Go to Settings -> Applications -> All applications.

In the list, find the program you want (like Chrome browser). Click on Storage. You'll see two buttons: Clear and Clear Everything. The first button removes only the cache, the second button resets the app to the state immediately after installation, removing logins and settings.

In Viber or WhatsApp, the cache can take up up to 10 GB of space from the videos and photos you see, and it is better to clean them through the built-in settings of the application itself: Settings -> Data and Storage -> Storage Use, which will allow you to selectively delete old media files, saving correspondence.

Some system services, such as Google Play Services or System UI, also have their own cache, and cleaning it can temporarily speed up work, but the system will quickly create new temporary files, which makes sense only if there are errors in the work of Google services.

Cleaning through Recovery (Advanced) mode

A more radical method that allows you to clear the system partition cache, which is not available through the usual interface, this method is useful if the phone is unstable after updating or installing a large number of programs.

Press the Volume Up button and the Power button at the same time. Hold them until the Mi logo appears, then release the power, keep the volume up. When the Recovery Mode menu appears, use the volume buttons for navigation and the power button for selection.

From the menu, select Wipe Cache (not to be confused with Wipe Data!). Confirm the action. The process will take a few seconds. Once complete, select Reboot. This method does not affect the user's personal files, but clears the temporary files of the operating system itself.

⚠️ Note: Some versions of Recovery may have different menus. If there is no "Wipe Cache" option, don't try to guess the functions of other items so you don't lose data. MIUI This section is often hidden or combined.

Third-party cleaning utilities

If standard tools are not enough, you can use specialized software, and the market leader for Xiaomi devices is the SD Maid application, which is able to find the tails of remote applications and system debris that a standard cleaner misses.

Another popular option is Files by Google, an official app from the search giant that safely analyzes memory and suggests removing duplicate files, blurred photos and unused apps, and is softer than the aggressive accelerators from the Play Market.

When using third-party software, always check permissions. A file cleaner application should not require access to your contacts or microphone. Trust only trusted developers with a good reputation.

Don’t install multiple cleaning apps at the same time. They may conflict with each other trying to access the same files, causing the Redmi Note 4 system to freeze.

Prevention of memory overflow

To avoid revisiting the cleanup every two weeks, you should change your smartphone usage habits: Enable syncing photos to the cloud (Google Photos or Mi Cloud) and set up automatic removal of local copies after downloading.

Check the Download folder regularly. That's where the app installers accumulate, PDF-Documents and pictures from messengers that are no longer needed. MIUI allows you to sort files by size, which helps to quickly find heavyweights».

Turn off autoplay of videos on social networks and instant messengers. This will not only save traffic, but also prevent the saving of many temporary video files in the app cache. Set up Telegram to automatically clean the cache of media files every 3 days or week.

💡

Regular prevention takes less time than dealing with the effects of overflowing memory: set up automatic cleaning and sleep well.

Also, you should periodically remove unused applications, even if you don't use them, they can update in the background and create temporary files. MIUI has a feature called Turbo Mode, which helps you quickly find and remove rarely used programs.
