How to Clear Cache on Xiaomi: A Step-by-Step Guide

Xiaomi, Redmi and POCO are famous for their performance, but over time, even powerful devices start to work slower. The main reason for this phenomenon is often the accumulated cache of applications and system services. Temporary files that are created to speed up the load of programs take up gigabytes of useful space over time, causing interface lags and overheating of the processor.

Many users mistakenly believe that removing unnecessary apps is enough to solve the problem. However, system debris continues to accumulate in hidden folders that are invisible when viewing a gallery. Understanding how to manage this data correctly is a key skill for any Android device owner. In this article, we will detail secure cleaning methods that will not damage your personal data.

Regular memory maintenance allows you to extend the life of the drive and maintain high speed of the operating system MIUI or HyperOS. We will look at both built-in cleaning tools and more advanced methods for advanced users. It is important to approach the process competently, so as not to delete accidentally saved passwords or progress in games.

What is cache and why you need to clean it

Cache is a memory area that is designed to store temporary files that are used most often. When you open an application, such as a social network or browser, the device downloads images, scripts and interface elements to the disk. When you restart, the system reads them from memory, which makes the program work instantly. Without the cache, the phone would have to re-upload this data from the network or internal memory each time, which would significantly slow down the process.

The problem arises when the cache size becomes disproportionate. Applications often do not delete old temporary files, creating new ones. This leads to inflated volume. In some cases, cache files can be corrupted, causing startup errors or incorrect content display. Clearing the cache allows you to reset these errors and make room for new data.

⚠️ Note: Clearing the cache does not delete your personal photos, contacts or correspondence, but logging in to some accounts may require re-authorization, as stored session data will be erased.

There are two main types of cache: application cache and system cache. The first is created by installed programs, the second is the operating system itself for operating the interface and background processes. Cleaning both types is safe and often recommended by manufacturers as part of preventive maintenance. Regular cleaning is especially important for models with a small amount of internal memory.

Use the Cleanup function in the Security app every 3-4 days to prevent critical memory filling.

Use of the built-in "Security" application

The easiest and safest way to delete temporary files on Xiaomi is to use a pre-installed system application that is optimized for MIUI and HyperOS shells, minimizing the risk of deleting important system files, a method that is suitable for most users who need to make room quickly without diving deep into the settings.

To get started, open the Security app (a shield and lightning icon) on the home screen, you'll see a Cleanup button with the amount of garbage. Click on it, and the system scans the device for temporary files, remnants of deleted apps and ad cache. The scanning process usually takes a few seconds.

Once the scan is complete, the system will suggest that you delete the files you find, but be careful: sometimes files that you might want to save, such as thumbnails from WhatsApp or temporary editor files, are included in the list, and in advanced cleaning mode, you can manually select which categories of garbage you want to remove, which gives you more control over the process.

The built-in tool also allows you to set up automatic cleaning, and in the Security settings, you can activate a feature that will notify you of a garbage buildup or clean it automatically when you reach a certain threshold, eliminating the need to perform manual checks and keeping the system on track.

💡

The built-in Security app is the most reliable way to clean up for ordinary users, as it eliminates the risk of deleting systemically important files.

Manually cleaning the cache of specific applications

If a particular program is not working properly or takes up too much space, it makes sense to manually clear its cache, especially for heavy-duty applications like Telegram, Instagram, TikTok and browsers, which tend to accumulate huge amounts of media files and temporary data.

To do this, go to your smartphone's Settings menu. Find the Apps section and select All Apps. Find the program you want in the list that opens. The interface may vary slightly depending on the Android version, but the logic remains the same.

Inside the app menu, you'll see Memory or Storage, which will show two values: the size of the app itself and the size of the data, you need a Clear (or Clear cache) button, and it's important not to confuse it with the "Erase Data" button, which will completely reset the application to the state after installation, removing logins and settings.

• 📱 Telegram: better to clean through the internal settings of the application (Data and memory) → Use of memory → Clear cache), as it allows you to save secret chats and settings.
• 🌐 Browsers: Clearing the browser cache will remove saved versions of sites, which can speed up their loading if they change, but will require re-entering passwords on some resources.
• 🎮 Games: The cache of games can weigh several gigabytes. its cleaning often requires reloading resources the next time you run, so do this only in case of acute shortage of space.

Regularly checking heavy apps helps maintain a balance between speed and free space, which some users do once a week, especially if they are actively using multimedia content, and it is worth noting that once the cache is cleared, the application can start a little slower the first time until it generates new temporary files.

Deep cleaning through the developer menu

For advanced users who want to gain full control of the system, there is the option of clearing the cache through the developer menu or special modes. This method allows you to remove the system cache, which is not available through standard settings.

The first step is to activate the developer mode. To do this, go to Settings → About Phone and quickly click on MIUI Version (or OS Version) seven times. After that, a new section will appear in the settings menu Additional → For Developers.

You can find options on the developer menu that are related to background processes and cache limits. While there may not be a direct "clean all cache" button, you can limit the number of background processes that indirectly affect the amount of garbage you create, and there is also a USB debugging mode that allows you to use computer utilities for cleaning.

One of the most effective ways to deep clean is to use Recovery mode. To log in, you need to turn off the phone, and then pinch the combination of the Volume Up and Power buttons before the Mi logo appears. In the Recovery menu (manage volume buttons, select power buttons), you need to select Wipe Data → Wipe Cache. Important: do not confuse Wipe Cache with Wipe All Data, as the second option will completely delete all your personal files and reset the phone to factory settings.

Automation and third-party utilities

There are a lot of third-party cleaning apps in the Android ecosystem, like CCleaner, Files by Google, or Clean Master. Should they be installed on Xiaomi? In most cases, there are more than enough built-in tools. Third-party utilities often work aggressively, closing the background processes, which the system then reopens, which only consumes battery power.

However, some tools can be useful for analyzing disk space, such as Files by Google, which is great at finding duplicate photos, old screenshots, and large files you forgot to delete, and using these analyzers once a month helps keep the file system in order without risking damage to system files.

Process automation is also possible through standard means. In the Security app, you can set up a cleanup schedule. In addition, many modern versions of MIUI themselves offer to clean up the garbage when the space is running out, and trust in the manufacturer's algorithms is justified in this case, because they better know the structure of their device's file system.

• 🚫 Avoid “accelerators”: Apps that promise to speed up the Internet or game by 200% are often advertising platforms and do not bring real benefits.
• ✅ Proven solutions: if you still want third-party software, choose products from well-known vendors (Google, Avast, Kaspersky).
• 🔋 Battery impact: Continuous cleaners in the background can reduce the autonomy of the device, as the processor is constantly busy analyzing files.

⚠️ Warning: Do not install multiple cleaning apps at the same time. They may conflict with each other, trying to access the same system resources, which will lead to unstable smartphone operation.

Common errors in memory cleaning

In an effort to make room, users often make mistakes that can lead to loss of important data or disruption of the system. One of the most common mistakes is deleting folders with the names of system services or folders with application data, thinking that it is garbage. Android/data contains important files of games and programs, its manual cleaning can lead to resetting of progress.

Another mistake is ignoring the cart completely, because on modern Xiaomi smartphones, deleted photos and videos don't disappear immediately, but instead move to a basket where they are stored for 30 days. They continue to occupy space. To really free up space, you have to go to the gallery, pick up the cart and clean it completely.

It is also not recommended to use the RAM (RAM) functions too often. Unlike older versions of Android, modern systems effectively manage RAM on their own. Artificial RAM release forces the processor to reopen applications, which consumes more power than if they just waited in the background.

💡

The best cleaning strategy is balance: use built-in tools for regular maintenance and manual cleaning only for problem applications.
