Where to Clean Cache in Xiaomi Phone: The Complete Guide

Xiaomi smartphone owners often face a situation where once-fast devices are slowing down and memory shortage notifications are increasing. One of the main reasons for the performance decline is the accumulation of temporary files that the system and applications save to speed up access to data. This digital “junk” can take up gigabytes of space, slowing down the operating system and causing interface freezes.

Clearing the cache is not just about removing bytes, it's about maintaining an Android device. Unlike deleting photos or documents, erasing temporary files won't cause any loss of important data, but it can make the gadget much more alive. It's important for Redmi and Poco users to understand the difference between the system cache and the application data so that they don't disrupt important programs.

There are several ways to do this, from using built-in MIUI tools to manually uninstalling through settings. Below we will detail each method, explain where to look for hidden memory parts and how often you need to do this cleaning to keep your smartphone running smoothly.

What is cache and why does it take up memory?

Cache is a buffer memory area where temporary files are stored to quickly load frequently used items. When you open an application or visit a website, your smartphone saves copies of them so that the next time you call, you don't download data again from the Internet. This speeds up the work, but over time, the volume of such files becomes redundant.

The problem is that many programs can’t delete old data on their own, and as a result, the cache grows, taking up precious space in the internal storage, and if free memory becomes critically scarce, the Android system becomes unstable, and errors can occur when installing updates or running heavy games.

⚠️ Warning: Clearing the cache is safe, but deleting the app's "Data" (not to be confused with the cache) will cause it to reset and log out.Be careful when choosing options in the memory management menu.

Social networks, messengers and browsers are particularly active in cache, for example, Telegram or VK can store gigabytes of images and videos viewed even if you haven’t saved them to the gallery. Regularly checking these sections helps keep the file system in order.

Use of the built-in "Security" application

The easiest and most affordable way to clear temporary files on Xiaomi devices is to use the standard system tool.The MIUI shell and its modern version of HyperOS have a pre-installed app that automatically scans the device for debris.

To get started, you need to find a label on your desktop or in the Tools folder called "Security" (a green shield icon) and when you run it, you'll see a "Clean" or "Clean" button, and the system will quickly scan and suggest that you delete the temporary files found, which is ideal for rapid prevention.

But the standard scanner doesn't always find all the hidden caches, and for more thorough cleaning inside the Security app, there's Deep Clean, which allows you to analyze large files, duplicate photos, and cache of installed programs in more detail, and you can selectively remove what's actually taking up space.

💡

Use the Deep Clean feature once a month to delete forgotten screenshots and residual files from remote applications.

Manually cleaning the cache of individual applications

If a particular program is slow or takes up a disproportionate amount of space, it is better to manually clear its cache through system settings.

The rest of the smartphone data.

To get to the menu, do the following: go to Settings, then select the App and click All Apps. In the list that opens, find the program you want (like YouTube or Chrome), click on it and select Memory or Storage. There will be a button to "Clear Cache."

It is important to distinguish between the two types of cleaning in this menu:

• 🗑️ Clear cache – only deletes temporary files without affecting your logins, passwords and game progress.
• 🔥 Clean everything (or Reset) - completely removes the application, returning it to a state immediately after installation.
• 📂 Data management – allows you to choose in detail what to delete, if the system provides such an option.

This method is especially useful for messengers like WhatsApp or Viber, which can inflate to huge sizes due to the cache of media files. By cleaning the cache manually, you free up space, but save correspondence and contacts.

⚠️ Note: If after cleaning the cache, the application stopped running or gives errors, try to clear its full data (reset), but first make sure you know the password from the account to re-enter.

Cleaning the cache through Recovery mode

For more advanced users, there is a way to clean the system cache through Recovery Mode, which removes temporary files from the operating system itself that may accumulate after MIUI updates or malfunctions.

To enter this mode, you need to turn off your smartphone completely. Then press the Volume Up button and the Power button at the same time. Hold them until the Mi logo or Recovery menu appears. This menu is controlled by volume buttons (up/down), and the power button selects.

In the Recovery menu, select a language (if available) or immediately look for Wipe Cache Partition. Confirm the action. The process will take a few seconds. Once complete, select Reboot to restart your phone.

This method is recommended if the phone is behaving strangely after a major system update, or if standard methods don't help free up space.

Comparison of Memory Cleaning Methods

Different cleaning methods have their pros and cons, and they have different levels of impact on the device, so to make it easier for you to choose the right option, we have prepared a method comparison table.

As the table shows, Xiaomi’s regular tools are the safest and most efficient for everyday use, and third-party apps often require extra permissions and can become a source of battery load themselves.

💡

For regular maintenance, the built-in Security application is enough, and use Recovery mode only for serious system problems.
