How to clean Xiaomi of cache: speeding up the smartphone

Modern Xiaomi smartphones have a powerful hardware, but over time, even flagship models start to work slower. The main reason for this is often accumulated cache — temporary files that applications save for fast loading of content. Over time, this data ceases to be useful, taking up precious space in memory and creating logical conflicts.

Cache cleaning is a safe and efficient procedure that allows you to return the device to the same sharpness of the interface. You do not need to be a technician to perform these actions, since MIUI and HyperOS provide convenient tools for memory management. In this article, we will discuss all cleaning methods, from standard to advanced.

Before we take action, it is important to understand the difference between cleaning the cache and completely dumping it. We will only remove temporary debris, leaving your personal photos, contacts and correspondence intact, a rapid prevention that is recommended to be carried out regularly.

What is cache and why it slows down Xiaomi

Cache is a buffer memory that stores the temporary data of running programs. When you open a social network tape or a website in your browser, the device stores copies of images and scripts. When you re-enter, the system downloads them from internal memory, rather than downloading them from the Internet again, which should speed up work, but the mechanism often fails.

The problem arises when the cache size becomes too large or files get corrupted. Instead of speeding up the launch, the smartphone spends the CPU resources searching for the desired snippet in a giant array of temporary data, which leads to interface friezes, long response to touches and fast battery discharge.

In addition, some applications, such as Telegram or TikTok, can take up gigabytes of space, saving the videos and pictures viewed. If you do not control this process, the free space will run out, and the system will start to work in emergency mode, forcibly closing the background processes.

• 🚀 Accumulation of temporary files reduces the speed of reading disk.
• 🐛 Damaged cache data causes app crashes.
• 🔋 Background indexation of garbage increases energy consumption.

⚠️ Cache is different from cookies. Cookies are small text files for authorization and site preferences, and cache are heavy media files and scripts.

Use of the built-in Security application

The easiest and safest way to free up space is to use a regular app from Xiaomi developers, which is built into the default shell and has access to system partitions that third-party programs often cannot reach without root rights.

To get started, look for an icon on your desktop called Security. Launch the app and click on a large green button with a zipper or shield, and the system will automatically scan and prompt you to remove the debris found.

After the initial cleaning, go to Cleanup, where the system will show you more detailed statistics: how much space is occupied by installation packages, files from the basket and application cache, you can selectively delete unnecessary data without touching important data.

• 🛡️ Deep scanning of system folders.
• 🗑️ Delete residual files after deleting programs.
• 📦 Cleanup APK-installer.

And it's important to note that automatic cleaning is sometimes too aggressive, and it can remove thumbnails of photos, which will keep the gallery open longer when you first start after the procedure, and that's okay, new thumbnails will be created automatically.

Manually cleaning the cache of individual applications

If a particular program is not working properly or takes up a disproportionate amount of space, it is better to clean its cache manually, which allows you to point the problem areas without affecting the operation of the entire system, most often for instant messengers and browsers.

To do this, go to Settings and select the App. Next, click All Apps. In the list that opens, find the program you want, like YouTube or Instagram. Inside the app menu, look for the Memory or Storage section.

You will see two main buttons: Clear cache and Clear everything (or Reset).Be careful: the first button deletes only temporary files, and the second button returns the application to state immediately after installation, removing your logins and settings.

💡

If the app crashes all the time, clear the cache first. If that doesn't work, use the Clear Everything feature, but remember to re-authorize.

It is especially useful to clean browser cache regularly, they accumulate huge amounts of data from visited sites. In the browser settings (Chrome, Mi Browser) there is also a function "History" -> "Clear History", where you can choose to delete only cached images and files.

Cleaning up garbage in social networks and messengers

Messengers are also getting a lot of attention, as they often have their own built-in cache storage mechanisms that don’t always show up correctly in the standard file manager.

Telegram handles the situation in the most intelligent way. Go to Settings -> Data and memory -> Memory Use. Here you will see a cache size slider. By clicking Clear cache, you will delete the downloaded media files, but the correspondence will remain on the server and re-upload as needed.

WhatsApp and Viber have a similar mechanism, but the files are stored locally. On WhatsApp, go to Settings -> Data and Storage -> Storage Management. You can delete large files or clear the entire cache. This will free up gigabytes of space if you are in many groups.

• 📱 Telegram stores cache in the cloud, you can safely clean.
• 💾 WhatsApp Stores Media Locally, Needs Periodic Cleaning.
• 📹 Video files occupy 80% of the volume of messenger cache.

⚠️ Before clearing the messenger cache, make sure that important files are saved to the cloud or computer, especially if you use rare document files.

Deep Clean Up Through Developer Menu and ADB

For advanced users who want to get the most out of it, there is a USB debugging method that allows you to remove the cache of system applications that are usually hidden from the user, which requires a computer and minimal command line knowledge.

First, activate the developer mode. Go to Settings -> About phone and quickly press the MIUI build number seven times. Then, in advanced settings, turn on USB Debugging. Connect the phone to your PC.

Using the Android Debug Bridge (ADB) tool, you can send a command to clear the cache of all applications at once, which requires installing the drivers and the tool itself on the computer.

adb shell pm trim-caches 99999999999

This command forcibly trims the app cache to a specified size (in this case, almost to zero if possible for the system).Be careful: after this procedure, the phone may run slower in the first 10-15 minutes, until it recreates the necessary temporary files.

Using ADB gives you complete control, but requires care. Errors in commanding can lead to unstable system operation, it is recommended to use this method only if the standard methods did not work.

Automation and overflow prevention

To avoid manual cleaning every week, you can set up automatic processes. New versions of HyperOS and MIUI 14 have a feature called Memory Acceleration, which automatically closes background applications and cleans the cache when free space falls below a critical level.

Third-party utilities like Files by Google can also be used.This app has a "Clean Up" feature that works softer than standard tools and offers to remove duplicate photos, blurred snaps and long-unused apps.

It's important to develop a habit of keeping track of storage. If your memory is more than 90 percent full, the speed of writing to the disk drops dramatically, causing general interface brakes. Try to keep at least 5-10GB of space free.

💡

Regularly cleaning the cache extends the life of the smartphone’s flash memory, preventing it from being worn out by constant overwriting cycles in crowded sectors.

• 🤖 Enable auto-cleaning in the Safety app.
• 📉 Remove unused applications.
• ☁️ Set up sync photos with the cloud.

Compliance with these simple rules will allow your Xiaomi to stay fast and responsive throughout its life.Don’t be afraid to clean temporary files – this is a regular maintenance operation of a digital device.
