Modern Xiaomi smartphones, including the popular Redmi Note 7 and Mi 9 series, are beginning to require maintenance over time. The accumulation of temporary files, residual application data and system debris inevitably leads to a slowdown in the interface. Users often notice that the device begins to react to touch longer, and the launch of familiar programs takes longer than usual.
Cache cleaning is one of the most effective measures to optimize the performance of the gadget. Cache memory is designed to speed up access to frequently used data, but when overflowing it begins to work against the user. In this article, we will discuss safe and proven ways to free up space on your Xiaomi without the risk of deleting important personal information.
Regular cleaning not only frees up gigabytes of space, but also extends the life of the device's internal memory. The system file system is more stable when the storage volume is at least 15-20% of the total. Let's look at what tools the MIUI shell and third-party utilities offer to solve this problem.
Why cache is overflowing and how it affects Xiaomi 7
When you use your smartphone, apps store a lot of temporary data, such as gallery images, buffered videos from social networks, or temporary browser files, and over time, this can reach several gigabytes, which is critical for models with limited built-in storage, such as 32 or 64 GB versions.
A crowded cache causes the file system to fragment. When a system has to look for free blocks to write new data among the scattered remnants of old files, the response rate drops. Interface lags and spontaneous closure of applications are the direct consequences of ignoring memory maintenance.
In addition, some apps may not work properly if their cache is corrupted or contains conflicting data. For example, Google Chrome or Telegram may not load new messages or display old versions of pages. Regular cleaning helps to reset these errors and restore normal logic of the programs.
⚠️ Warning: Cleaning the app cache doesn’t delete your personal correspondence, logins, and passwords. However, cleaning up the data (not to be confused with cache) will completely reset the app to the factory state.
💡
Use the Cleanup function in the standard Security app at least once a week to maintain optimal system speed.
Use of the built-in "Security" application
The MIUI shell, installed on all Xiaomi smartphones, has a system tool preinstalled for maintenance. It is the safest and most recommended cleaning method by the manufacturer. The Security app analyzes the system and suggests removing unnecessary files in one click.
To start the procedure, look for a green shield icon on your desktop. Once you open, click the large Scan button. The system will automatically find debris, including app cache, advertising files and remnants of deleted programs. Click the Clean button to remove what you find.
An advanced analyzer is also available inside the app. Go to Clearer to see the details by file type, and you can selectively remove the cache of the big apps like YouTube or Instagram that consume the most resources.
- 🧹 Open the Security app and click Cleanup».
- 📂 Wait for the system scan to be completed.
- 🗑️ Press the cleaning button to remove garbage.
- 📊 Check the Deep Clean section to analyze large files.
☑️ Checking before cleaning
Manually cleaning the cache of individual applications
Sometimes automated tools can't remove the cache of a particular problem application, and in such cases, you need to intervene manually, which is especially true for instant messengers and social networks, where a huge amount of media files accumulate.
Go to Settings → Apps → All apps. Find the program you want (like VKontakte or TikTok) and select Memory or Storage, where you will see two buttons: Clear cache and Clear everything.
It's important to understand the difference between these actions. The first button deletes only temporary files, the second one erases all data, including authorization. To solve performance problems, the first option is usually enough. If the application is not working correctly, you can try to clean all data, but you have to re-enter your username and password.
| Action. | What's removed | Impact on the account | Recommendation |
|---|---|---|---|
| Clearing the cache | Temporary files, thumbnails | No influence. | Safe, you can do it often. |
| Clearing the data | All files, settings, logins | Full exit. | Only when there's a failure. |
| Deletion of the annex | Program and all data | Installation required | If the application is not needed |
| Resetting settings | The whole system and data | Total loss of data | Extreme measure |

Cleaning through the Recovery Mode (Recovery Mode)
If the smartphone is unstable or the interface is not responsive, you can use recovery mode. This is a deeper level of interaction with the Android system. On Xiaomi devices, this menu is logged in by a keyboard combination when the device is off.
Turn off the 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, continue to keep the volume. In the menu that appears, the navigation is done with the volume buttons, and the choice is made with the power button.
Find Wipe Data or Clear Cache (the name may vary depending on the version of MIUI). Be very careful: selecting Wipe All Data will result in a complete reset of the phone to the factory settings with all photos and contacts deleted.
⚠️ Note: Entering Recovery mode on carrier-locked devices or devices with an unlocked bootloader may have its own peculiarities. Make sure you choose to clean the cache (Wipe Cache) rather than completely reset.
Third-party utilities for deep cleaning
Standard MIUI tools are sometimes not enough to remove hidden debris. Third-party developers offer powerful tools for analyzing the file system. However, it is worth remembering that installing unnecessary applications is a waste of resources.
One of the most popular and secure web sites is Files by Google, which can find duplicate files, blurred photos and long-unused applications. Another good option is SD Maid, which specializes in finding dead files left over from deleted programs.
When using third-party software, always check the permissions requested. The file cleaner application does not need access to your contacts or microphone. Trust only trusted developers and download the software exclusively from the official Google Play store.
- 📲 Files by Google – Smart File Cleaning and Management.
- 🧹 SD Maid – Professional search for residual files.
- 🚀 CCleaner – a classic optimization tool.
- 🛡️ Avast Cleanup – Cleaning and Speeding Up.
💡
Third-party apps give more detailed control, but Xiaomi’s standard Security app is better integrated into the system and safer for inexperienced users.
Prevention and optimization of memory
To avoid having to deal with space shortages, you need to adopt a few habits: Regular maintenance takes less time than emergency rescue of a crowded smartphone; a systematic approach prolongs the life of the device.
Enable automatic cleaning in the Security settings. It is also recommended to disable auto-save media files in messengers, unless urgently necessary.
Keep an eye out for MIUI updates. Xiaomi engineers are constantly releasing patches that optimize memory and fix resource leaks. The latest version of the software is the key to the stable operation of your Xiaomi 7.
Don't store files on your device that you haven't used in a long time. Archive old documents and delete installation files. APK-These simple steps will help to maintain the high speed of your gadget throughout the life of the device.
