How to Delete Cache on Xiaomi Redmi 7: Effective System Cleanup

Xiaomi’s Redmi series is well-deservedly popular for its excellent price-performance ratio. However, even powerful hardware slows down over time when the system partition is full of temporary files. The Redmi 7, launched in 2019, is still in use by millions of people, and optimization remains a pressing issue for it.

Cache accumulation is a natural process for Android and MIUI. Apps store data for fast loading, browsers cache visited pages, and system services create temporary reports, a problem that occurs when these files stop updating or occupy a critical volume, causing interface failures.

In this article, we will take a look at all the ways you can clean your app cache and system files, learn how to distinguish between safe methods of garbage removal and understand when you need to interfere with system processes, and manage memory correctly will allow your device to work as fast as on the day of purchase.

What is cache and why it should be removed

Cache is a memory area that stores the temporary data needed to quickly access frequently used information. When you launch YouTube or Telegram, the app reads some of the data from the cache so it doesn't re-upload it from the network. This speeds up work, but over time, the folder can grow to several gigabytes in size.

The main problem with older versions of MIUI is that the system does not always manage these files efficiently automatically. Some applications can store broken links or outdated images that only take up space. Clearing the cache helps eliminate software errors associated with the conflict of old and new data.

You have to understand the difference between the data of the application and its cache, and if you delete the data, you lose the logins, the settings, and the progress in the games, and deleting the cache is safe, you just reset temporary files, forcing the application to recreate them in an up-to-date way.

⚠️ Before conducting a deep cleaning of the system, make sure that important photos and documents are stored in cloud storage or on an external medium to avoid accidental loss of information.

Regular memory maintenance is particularly important for models with a small amount of built-in storage.Redmi 7 frequently supplied 32 or 64 GB of memory, of which the system takes up a significant portion. 1-2 GB can dramatically affect the speed of the interface.

Standard cleaning through the Security app

The easiest and safest way to clean up garbage is to use a built-in tool from Xiaomi. MIUI shell is equipped with a powerful system module that scans the device for temporary files, which is suitable for daily use and does not require special knowledge.

To get started, look for an icon on your desktop called "Security" (green shield). Launch the app and click on the "Clean up" button. The system will automatically scan all the sections and prompt you to remove the debris found, which usually takes no more than 10-15 seconds.

Once you scan, you'll see a list of files that you can delete, which includes remnants of deleted applications, temporary installation files, and cache of system services, and be careful, sometimes you'll find files that you might want to save, like thumbnails from a gallery.

In the advanced cleaner settings, you can select file types for analysis, it is recommended to periodically check the "Big Files" section where forgotten videos or archives may be hidden, and the "APK Cleanup" feature, which deletes installation files of applications already on the system, is also useful.

• 🚀 Click the Clean button to remove all the trash found in one action.
• 📂 Use the “Deep Clean” option to analyze large files and duplicates.
• ⚙️ Set up automatic cleaning in the Settings menu of the Security app».

Removing the cache of individual applications manually

Sometimes a standard cleaner can’t get to the cache of specific “heavy” programs, such as social networks or navigators, and in such cases, manual intervention is required through the Android settings menu, which allows you to point to free up space without affecting other processes.

Go to Settings → Apps → All apps. Here is the full list of installed software. Find the app that consumes the most space (usually Instagram, TikTok or Google Chrome) and click on it.

In the menu that opens, select Storage, and you'll see two buttons: Clear and Delete, and we're interested in the Clear button (or Clear cache depending on the version of MIUI), and clicking on it will only delete temporary files, leaving your accounts and settings intact.

If an application doesn't work properly, like it crashes when it starts, you can try a more radical method called "Clean Everything" (or "Reset"). Importantly, this action will delete all the application data, including authorization. You'll have to re-enter your username and password, but this often solves the freeze problems.

Special attention should be paid to the Gallery system app, which can grow to huge sizes over time due to thumbnails of deleted photos. Regularly cleaning the gallery cache through the application menu helps to avoid lags when scrolling through albums.

Cleaning the cache through Recovery mode

There is a deeper level of cleanup available through Recovery Mode, which allows you to delete temporary files that may be blocked by the operating system running, which is useful if the phone is unstable or after a firmware update.

To enter this mode, you need to turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power, but continue to keep the volume until the recovery menu appears.

Navigation in the menu is done with volume buttons (up/down), and the choice of item is made by the power button. Find the Wipe Cache. Don't confuse it with Wipe Data, which will completely reset the phone to factory settings!

The sequence of actions in Recovery:


1. Turn off the phone.




2. Clutch Volume + and Nutrition.




3. Select Wipe Cache.




4. Confirm action.




5. Select Reboot.

After cleaning, the system will suggest restarting. The first run may take longer than usual, as Android will recreate the necessary system files. Don't worry if the device warms up at this point - this is a normal optimization process.

Storage analysis and work with files

Visualizing what’s taking up space on your Redmi 7 helps you understand where the main memory eaters are hiding. The built-in storage analyzer shows the distribution of space by category: apps, images, videos, documents, and more.

Often, users don't realize that messengers like WhatsApp or Viber store all the media they receive in their phone's memory, and even if you look at a photo and forget about it, it takes up space, and you can turn off auto-save in the gallery in the settings of these apps.

Download folder is another place where digital junk accumulates, PDF-Documents and saved images from your browser can lie there for years, and auditing this folder regularly through a file manager is a good habit.

Using third-party file managers like Total Commander or FX File Explorer, gives you more flexible tools to find duplicates and large files.They let you sort files by date of creation, which is convenient for finding old forgotten content.

Automation and useful optimization tips

So you can set up automatic scripts to avoid manual cleaning all the time, and the Security app has a Planner feature that allows you to set the time to automatically clean up the garbage, for example, you can set a task at 3 a.m. when the phone is not in use.

It is also recommended to disable auto-update applications over the mobile network, leaving this feature only for Wi-Fi.This will prevent heavy updates from downloading in the background, which can temporarily inflate the cache of network services.

💡

Use the “Light App” (Lite). For older models like Redmi 7, there are lighter versions of Facebook, Instagram, and other services that consume less memory and traffic.

Remember to add memory extension if it’s available in your version of MIUI, which allows you to use some of your internal memory as virtual RAM, which can help with heavy applications, although it doesn’t replace physical cache cleaning.

⚠️ Note: Do not use the dubious accelerator apps from the Play Market. They are often a source of advertising and junk, and their effectiveness is lower than that of Xiaomi’s built-in tools.

Regularly restarting your smartphone at least once a week also helps to clean up RAM and reset the hanging processes, a simple procedure that often solves small software glitches without deep interference with the system.

💡

Integrated approach: The combination of manually clearing heavy app cache and using an in-built scheduler gives the best result for Redmi 7 performance.
