Owners of the popular Xiaomi Poco X3 NFC model may experience slowdowns or lack of free space over time. Cache files accumulate during the use of applications and browsers, taking up valuable space in internal memory. Regular cleaning of this temporary data helps maintain high performance of the device and prevents the occurrence of system errors.
The process of freeing up memory on the shell of MIUI or HyperOS has its own features that differ from standard Android. System garbage can be hidden in different sections, and simply removing applications does not always solve the problem. In this article, we will discuss safe cleaning methods that do not require root rights and will not lead to the loss of personal photos or contacts.
It is worth understanding that temporary files are created to speed up the load of frequently used functions, but their excess gives the opposite effect.Proper maintenance of the Poco X3 NFC extends the life of the drive and ensures stable operation of the Snapdragon 732G processor.
⚠️ Note: Before starting any manipulation of system files, we strongly advise you to back up important data, although the methods described below are standard and secure.
What is cache and why remove it on Poco X3 NFC
Cache is a clipboard that stores temporary data for quick access. When you open an app for the first time, the system downloads resources from the disk, but when you re-run it takes them from the cache. On Xiaomi Poco X3 NFC with its large 120Hz screen, graphical interface elements are also cached for smooth animations.
But over time, these files can grow to a few gigabytes. Obsolete data can conflict with new versions of apps, causing crashes or freezes. If your smartphone is slower or apps are out of service immediately after launch, it is likely that the problem lies in the crowded cache of applications.
Cleaning doesn't delete your personal files, logins or passwords. It's a technical maintenance procedure that's useful to do regularly, especially for heavy social media and messaging apps, which tend to accumulate a huge amount of garbage.
- 🚀 Freeing up internal memory to install new games and apps.
- ⚡ Acceleration of program launch and interface operation MIUI.
- 🛡️ Removing software errors and version conflicts.
- 🔋 Reducing the load on the processor when searching for data.
Use of the built-in Security application
The easiest and most reliable way to clean up your system debris on a Poco X3 NFC is to use a regular developer utility. Security is deeply integrated into the shell and has access to all the necessary parts of the file system. It automatically scans the device and suggests that you delete unnecessary files.
To start the procedure, open the menu and find the shield icon. Click on the Cleanup or Speed button, and then the system will analyze it. You will see a list of temporary files that you have found that can be safely deleted with a single click. This is a basic method that is recommended to be done at least once a week.
In the advanced cleaner settings, you can select file types for analysis. Xiaomi algorithms allow you to separately clean the cache of installed applications, remnants of deleted programs and advertising files. Using the built-in tool ensures that you do not delete anything extra that could disrupt the system.

What if the cleaner doesn’t find the garbage?
Manually cleaning the cache of specific applications
Some programs, like Telegram, YouTube, or Instagram, accumulate gigabytes of data that a standard cleaner can ignore. For deep cleaning, you need to go into the settings of each heavy app separately, which allows you to free up significantly more space than with a general cleanup.
Go to Settings -> Apps -> All Apps. Find a program you want, like the Chrome browser, in the app menu, look for Memory or Storage, and you'll see two buttons: Clear cache and Clear everything.
It is important not to confuse these functions. The Clear Cache button will only delete temporary files, saving your account acca and settings. The Clear Everything (or Reset) button will return the application to state immediately after installation, removing logins and saves. Be careful when choosing an action so as not to lose authorization data.
| Annex | Type of data in the cache | Safety of cleaning | Recommended frequency |
|---|---|---|---|
| Telegram | Photos, videos, files | Safe. | Once a month |
| YouTube | Preview, thumbnails. | Safe. | Once a week. |
| Google Chrome | Website pictures, scripts | Safe. | Once every 2 weeks |
| Tape, storis, reels. | Safe. | Once a month |
⚠️ Note: When clearing the browser cache, you can log out of accounts on some sites as cookies are deleted.
Cleaning through the developer menu and engineering menu
For advanced Poco X3 NFC users, a deeper level of system management is available, the developer menu allows you to control processes in the background and clean data in more detail, and to activate this mode, you need to click on the build number several times in the About Phone section.
Once activated, a new section for developers will appear in the menu, where you can find options to limit background processes, which indirectly affects cache proliferation, there is also an engineering menu called through the code, but it requires caution. Using code ##4636## opens the testing menu where you can check usage statistics, but direct cache cleaning there is usually not available on new versions of Android.
A more effective method in this section is to reset network settings or reset application preferences. This does not delete personal data, but returns system settings to factory values, which often solves problems with freezes caused by errors in configuration files.
- 🔧 Activation of the developer mode through 7 clicks on the version MIUI.
- 📉 Limiting background activity to save resources.
- 🔄 Reset application settings without losing user data.
- 📊 Monitoring the use of memory in real time.
💡
Use the Advanced Cleanup feature in the Security app to find large files forgotten in the Downloads folder that often take up space alongside the cache.
Automation of cleaning with scripts and tasks
The MIUI shell allows you to create automatic scripts that will clean the cache on a schedule or when conditions are met. This eliminates the need to do this manually. You can set up a task that will start cleaning when the battery level drops below a certain value or when the phone is connected to the charger.
To create a script, use the Settings -> Advanced Settings -> Autostart app (or a separate Scripts app if available in your firmware version). Select a trigger, such as "Daily at 03:00" and the "Clear Memory" action, which ensures your Poco X3 NFC will meet the morning with clean RAM and fresh cache.
There are also third-party launchers and utilities, but their use on Xiaomi is not always justified due to the aggressive optimization of the battery system.
⚠️ Warning: Don’t install questionable “accelerators” from the Play Market. They often consume a lot of resources and show intrusive advertising, slowing down Xiaomi Poco X3 NFC.
💡
Automating maintenance processes is the best way to forget about memory shortages and enjoy a fast smartphone without manual intervention.
