Xiaomi smartphones are famous for their functionality and affordable price, but even the most powerful models eventually start to run slower. The main reason for the decline in performance is the accumulation of system “junk” – temporary files, remnants of remote applications and cache of services. It is a natural process that affects the MIUI or HyperOS operating system, regardless of whether you have a flagship or a budget model of the Redmi series.
Users often notice that the device starts to heat up and the space disappears for no apparent reason. Internal memory is filled with duplicates, thumbnails of photos and error logs that are created daily. If you do not conduct regular revisions, this can lead to a critical slowdown of the interface and even malfunctions in important applications.
In this article, we will take a look at safe and efficient ways to bring your gadget back to its factory speed. You will learn to distinguish systemically important data from excess ballast and understand which tools are best used for deep cleaning. Regular maintenance extends the life of the device and keeps it fast.
Built-in cleaning tools for the system
The first thing to start with is the standard Security app, which is pre-installed on all the brand's devices, and it's not just an antivirus, it's a powerful resource management combine, and when you start, Cleanup scans the device for temporary files, ad cache, and installer residual packages.
The system algorithm is quite aggressive and often suggests removing files that you may need, such as thumbnails of images from messengers or cache cards. So always look at the list of categories before confirming actions. Autocleaning is convenient, but requires control from the user.
It is important to note that the built-in tool does not always find deeply hidden logs or duplicates in the download folders. It is quite enough for basic maintenance, but additional actions will be required for deep cleaning. Regular use of this tool (once a week) helps to maintain the amount of free space in the normal way.
⚠️ Warning: Do not use Memory Acceleration too often. Android manages RAM efficiently, and the constant forced unloading of processes only increases battery consumption.

Turn on the schedule cleaning function in the Security settings so that the phone automatically makes room at night when you sleep.
Manual cleaning of app and messenger cache
The main consumers of internal memory are traditionally social networks and instant messengers. Telegram, WhatsApp and Viber store every photo and video file viewed in the memory of the phone, even if you have already deleted them from the chat. This creates a huge amount of hidden data that is not always visible in a standard Explorer.
To free up gigabytes of space, you need to go to the settings of each heavy application separately. In the program management menu, select "Storage" and click "Clear Cache." It is important not to confuse the cache with data: cleaning the data will completely reset the application, including your logins and correspondence, if they are not stored in the cloud, and the cache contains only temporary files that can be deleted without losing your account.
The messaging gallery is a big focus, and inside WhatsApp or Telegram settings, there's a data and memory section where you can delete all downloaded media files at once or selectively, and it's the most efficient way to quickly get a few gigabytes of free space, and users often don't realize that old stickers and videos you've watched take up to 70 percent of the Documents section.
- 🗑️ Open the settings of a particular application through the phone menu.
- 📂 Go to the "Storage" or "Memory" section".
- 🧹 Click "Clear Cache" by making sure you haven't selected "Clear Data".
- 💬 Check the internal settings of messengers to remove old media.

Storage analysis and search for hidden files
Often memory is occupied with files that the user does not even know exist, such as logs of system updates, error reports or forgotten files from browser downloads. Standard Explorer is not always convenient for visualizing memory, so it is better to use the built-in storage analyzer.
In the Settings menu -> About Phone -> Storage, the system will show you a diagram of the space distribution, and you can see what takes up the most space, apps, images or system files, and by clicking on the category, you will be taken to a detailed list where the files are sorted by size, which allows you to quickly find and delete forgotten movies or archives.
Special attention should be paid to the folder MIUI/Gallery/cloud/cache, where cloud photos can accumulate. It is also worth checking the Android/data folder, but you need to be extremely careful here. Deleting the contents of the folders with the names of the programs you need can lead to resetting their settings or losing progress in games.

Use of third-party snails and file managers
If built-in tools are not enough, specialized applications come to the rescue. However, installing cleaners on Xiaomi is often redundant, as they can conflict with the MIUI energy saving system. It is better to use proven file managers, such as Files by Google or Total Commander, which allow you to see hidden files and duplicates.
Apps like Clean Master or CCleaner can be useful for finding duplicate photos and empty folders, scanning devices deeper than standard tools, but it’s worth remembering that these programs consume resources on their own and can display intrusive ads claiming that the phone is “infected with viruses” to attract attention.
The safest approach is to use open source tools or official Android utilities, which require no extra permissions and are transparent to the user, and the main rule is not to give third-party software superuser rights (Root) unless absolutely necessary.
Below is a comparison table of cleaning methods that will help you choose the best option for your situation:
| Cleaning method | Security | Efficiency | Difficulty |
|---|---|---|---|
| Built-in application | Tall. | Medium | Low. |
| Manually cleaning the cache | Tall. | Tall. | Medium |
| Third-party utilities | Medium | Tall. | Low. |
| Total reset (Reset) | Low (Data Loss Risk) | Maximum | Tall. |
Removal of system debris and logs
There are hidden partitions on Android that record debugging logs and app reports, and over time, these text files can grow to impressive sizes, and cleaning those partitions is safe, because the system automatically creates new logs when needed.
You can use an engineering menu or commands through ADB to access some hidden cleaning functions, but for the average user, this can be dangerous. An easy way is to clear the data from the system application Downloads or Download Manager. This will delete the list of downloaded files, but not the files themselves, if they are stored in memory.
It's also worth checking the folder. MIUI/debug_log. If you are not a developer or you don’t send error reports to Xiaomi, the contents of this folder can be painlessly deleted.
⚠️ Warning: Never delete files from folders with system service names (e.g. com.android.systemui) unless you know exactly what they are intended for.
Prevention and optimization of the smartphone
To avoid going back to cleaning every two days, it's important to have the right digital hygiene: Turn off autoloading media files in messengers, set up automatic cleaning of the shopping cart in the gallery and in the Explorer app every 30 days, which will prevent the accumulation of deleted but still occupying files.
Use cloud storage for photos and videos. Services like Google Photos or Xiaomi Cloud allow you to store originals on the network, leaving only optimized copies on the device, which significantly saves space without losing the quality of viewing from the phone screen.
Update your system regularly. Newer versions of MIUI and HyperOS often come with patches that improve file system and compression mechanisms. Older versions of firmware may contain bugs that can cause system partitions to proliferation.
💡
The main secret of a clean phone is not the number of cleaners installed, but the habit of turning off auto-save media in chat rooms and regular manual control of the Download folder.
