Modern smartphones like Redmi and Poco have a lot of hardware, but over time, even the top-end models start to run slower, a natural process of accumulating digital junk that is inevitable when you use it. The MIUI or HyperOS operating system collects huge amounts of temporary files, app cache and residual data after remote programs.
Users often notice that notifications of memory shortages are appearing more often, and the interface begins to slow down when switching between tasks, the solution is competent and comprehensive cleaning of the device, and you should not immediately resort to a complete reset, since there are many more gentle methods to return the performance of the system.
In this article, we will discuss all available optimization methods, from built-in tools to advanced methods of cleaning system partitions. You will learn which folders can be deleted without fear of damaging the system, and how to properly configure automatic maintenance. Safe cleaning is possible only with an understanding of the structure of Android files, so we will pay special attention to the fact that you can not touch.
Use of the built-in Security application
The first and most logical step for any Xiaomi owner is to use a regular optimization tool, and the company has built a powerful Security app into the shell that can find hidden debris that is invisible to a standard conductor. Launch the app and select Cleanup to scan the device.
The system will analyze the cache, residual files and unnecessary APK installation packages. It is important to understand that the algorithm is aggressive, so before the final deletion, it is better to manually check the list of found. Often, the category of "junk" falls into the thumbnails of photos or cache of cards, which will have to be downloaded again the next time you use the navigator.
For deep cleaning, go to the garbage cleaner section inside the app, and you can have more detailed settings, including cleaning up large files and duplicate photos, and using this tool regularly helps keep the system on track without the need for third-party software.
- ๐งน Click the "Scan" button to start the memory analysis.
- ๐ Manually check the "App Cache" section before deleting data.
- ๐๏ธ Use the Deep Cleansing feature to find forgotten videos.
- โ๏ธ Set up automatic cleaning in the app settings menu.
โ ๏ธ Attention: Memory acceleration function" (RAM Booster) often just closes the background processes. On modern versions of Android, this can even slow down the launch of applications, since the system has to open them again, rather than deploy them from memory.

Turn on automatic garbage cleaning in the "Security" settings when the screen is blocked - this will keep order without your participation.
Manual cleaning through Conductor and storage analysis
Automatic cleaners don't always understand what's important to the user, for example, they might skip a folder with bug logs or temporary messenger files that take up gigabytes, and you need to open a standard Explorer and go to the root of internal memory.
And look at the folders that have the names of popular apps like Telegram, WhatsApp, Instagram, and they often store videos and pictures that you don't need anymore. Telegram/Telegram Images where the cache of channels accumulates.
Itโs also worth checking the Download folder. Browsers and social networks often save everything youโve ever opened there. Deleting old documents and game installers can free up 1 to 5 GB of space instantly. Carefully check content before mass removal so you donโt erase important checks or tickets.
Pay special attention to the folder MIUI It's at the root of the memory. It's got a subfolder inside it. debug_log, So if you're not a developer and you're not debugging the firmware, you can delete the contents of that folder, and it can grow to a huge size.
Cleaning cache and data of specific applications
The most voracious elements in Android are social networks and browsers, which store every image and video you see in a local cache to upload faster when you re-watch it, and over time, that cache becomes huge and often corrupted, causing bugs in the software.
To clear the data of a particular application, go to Settings โ Apps โ All apps. Select the desired program (for example, YouTube or TikTok) and find the item "Memory". Here you will see two buttons: "Clear cache" and "Clear everything" (or "Reset").
Using the Clear Everything button is like reinstalling the app: you will crash out of your accounts and your settings will reset. Use this option only if the app is not working properly or takes up critical space and the regular cache is no longer helping.
| Type of data | What's removed | Is it safe? | Impact on the account |
|---|---|---|---|
| Cash. | Temporary files, pictures, thumbnails | Yeah, totally. | No (remain in the system) |
| Application data | Logins, settings, saves, databases | Careful. | Yes (re-entry required) |
| Cookies | Tracking sites, saved sessions | Yes. | Partial (exit from websites) |
For Chrome or MI Browser, cache cleaning is a standard maintenance procedure, which solves problems with the โcurveโ display of sites and speeds up the browser itself, and it is recommended to do this once a month when you are actively using the Internet.
Removing System Garbage and Hidden Folders
In the Xiaomi file system, there are hidden directories that are not visible in normal viewing, but take up space. To access them, you need to enable the display of hidden files in the Explorer, often there you can find folders from long-deleted games or applications.
The Android/data folder is particularly noteworthy, which used to be free to access, but newer versions of Android have limited access, but if you have an extended file manager (like MT Manager or Total Commander with plugins), you can clear the cache inside that directory.
Some users try to delete folders with the names of Google or Xiaomi system services, which you canโt do unless you know exactly what the process is for, which can lead to a cyclical reboot of the phone or the disappearance of important features such as the camera or sound.

Also check the Tencent folder if you use Chinese versions of games or apps like WeChat, which create huge amounts of data that often donโt get deleted even after the app itself.
Automatic cleaning and optimization
To avoid manual cleaning, you can set up the system to automatically service, and there are built-in task schedulers in the MIUI and HyperOS shells, and go to the Security settings and look for the garbage cleanup section.
Activate the Auto Clean switch. The system will self-delete temporary files when the phone is idle and connected to charging. This is the ideal scenario, since it does not interfere with the user and does not consume battery power in active mode.
You also need to set up memory notifications, set a 90 or 95 percent threshold so that your phone can warn you before serious interface brakes start, and proactive control is always more effective than dealing with consequences.
- ๐ Set up a weekly scan in the background.
- ๐ Enable notification when memory is more than 85%.
- ๐ซ Turn off autoloading of unnecessary apps in battery settings.
- ๐ธ Set up sync with the cloud to free up local space.

Don't forget the Recycle Bin in the Gallery and Explorer. Deleted files often lie there for another 30 days, continuing to take up space. Periodic cleaning of the Recycle Bin is an easy way to get back a few gigabytes.
Radical methods: resetting and flashing
If the software cleaning doesnโt work and the phone keeps running slowly, it may be that the problem is deep file system errors or conflicts after a lot of updates, leaving it to a full reset to the factory settings (Hard Reset).
Before this procedure, make sure to back up all important data to your computer or to the Mi Cloud. Reset will delete absolutely everything: contacts, photos, apps and settings. The phone will become the same as you bought it in the store.

After resetting and clean installation of applications (without restoring backups of system settings), the smartphone starts to work as quickly as possible.
โ ๏ธ Warning: Before resetting, make sure you remember the password from your Mi Account and Google account. Once turned on, the phone will require them to prove ownership (FRP lock, and without them the device will become a "brick".

A full reset is a last resort that solves 99% of software performance problems, but takes time to reconfigure the device.
In extreme cases, when even a reset doesnโt work (which is rare), users resort to flashing through a computer with clearing all partitions (Clean Install), which requires skill and downloading official firmware from miui.com.
