How to Clean up Waste on Xiaomi: A Complete Guide to Optimization

Xiaomi smartphones are famous for their performance and rich functionality of the MIUI shell, but even the most powerful devices eventually start to work slower. The main reason for this phenomenon is the accumulation of large numbers of temporary files, remnants of remote programs and cache, which takes up gigabytes of useful space. Users often face a lack of space to install updates or new applications, which causes irritation and reduces the comfort of using the gadget.

Cleaning up a system isn't just about removing a couple of photos, it's a complex process that requires understanding the structure of files. If you want to get your device back sharp and free up valuable resources, you need to know where hidden data is hiding. In this article, we'll go through all the techniques, from standard tools to deep manual cleaning, to make your Android work like new.

It's important to understand that blindly deleting files can lead to loss of important data or malfunction of applications. So before starting any manipulation, it is worth understanding the types of garbage and using proven methods. System update cache and error logs can take up to 10 GB of space without being noticed by the user. Let's start with basic but effective built-in tools.

Use of the built-in "Security" application

The first tool Xiaomi owners should look at is the pre-installed Security app, a standard tool developed by the company’s engineers specifically to optimize the shell. MIUI It scans the system for temporary files, APK-installers and residual debris that accumulates during the work.

To start the procedure, you just need to open the application and click on the “Clean up” button. The system will automatically analyze the storage and prompt you to delete secure files. However, you should not rely only on the automatic mode, since it often skips specific messenger folders.

In the deep cleaning section, you can see large files that are rarely used and duplicate photos. Be careful when removing the contents of the Download folder, as there may be important documents there. The app will also show the amount of cache that can be safely deleted without losing personal data.

It's worth noting that regular use of this tool helps keep the system on track. The app cache is updated constantly, so weekly prevention will avoid critical memory overflow. If a standard scanner doesn't find a lot of debris, it doesn't mean it's not there - it's just hidden deeper.

Manual cleaning through File Manager

More advanced users should use the built-in File Manager to manually review folders. Automatic scanners are often afraid to delete files whose destination they cannot pinpoint, leaving the user with the right to decide their fate. Go to the Internal Memory section and carefully examine the directory list.

Special attention should be paid to folders with the names of popular applications such as Telegram, WhatsApp and Viber, which often store videos and images that are viewed and are no longer needed, but continue to occupy space. Android/media You may have heavy files from social media.

• 📁 folder DCIM — Here are your photos and videos, check the basket in the gallery.
• 📁 Bluetooth directory – often packed with forgotten files from other devices.
• 📁 folder MIUI — It contains logs and screenshots that can be safely deleted.
• 📁 Tencent Directory – a garbage storage from Chinese versions of apps and games.

⚠️ Warning: Never delete files from System, Config or.xml file extensions at the root of the system unless you are 100% sure of their purpose.

After removing the extra files, be sure to clear the bin in the file manager itself, as deleted data is often moved there temporarily.This manual work allows you to free up much more space than automatic cleaning, but requires more care and knowledge.

Cleaning the cache and application data

Each app that is installed accumulates its own cache to speed up work. Over time, this temporary data can grow to giant sizes, especially for browsers, streaming services and instant messengers. Clearing the cache does not delete your accounts or correspondence, but resets temporary files.

To do this, go to Settings → Apps → All apps. Select the app that takes up the most space (usually social media or YouTube) and click “Clean.” From the menu that opens, select “Clear Cache.” If you want to reset the app completely, you can select “Clean all data,” but this will require re-authorization.

It is recommended to check the list of the most “heavy” applications regularly, and it often happens that a rarely used program takes up several gigabytes of space, and removing and re-installing such an application also helps to get rid of accumulated garbage that is not removed by standard methods.

Storage analysis and search for hidden files

To visualize what exactly is taking up space on your Xiaomi, it’s convenient to use the built-in storage analyzer, which is located in the Security app or in the memory settings, and the graphical view allows you to quickly identify the “eaters” of space that may have escaped attention.

Users often forget about downloaded offline maps in navigators or TV shows in streaming services, which can weigh tens of gigabytes. Check the settings of Google Maps, Yandex Maps, Netflix and Spotify apps for stored content.

Use this table as a cheat sheet for manual cleaning, knowing where it is gives you complete control of the device, and don't be afraid to delete temporary files, the system will recreate them if you need them to work properly.

Removal of duplicates and similar photos

Xiaomi's camera of modern smartphones takes high-quality shots that take up a lot of space. Often, the gallery accumulates series of identical shots taken in serial mode, or screenshots that are no longer relevant. The MIUI gallery has a built-in duplicate search feature.

Open a gallery, go to albums and find the recent folder or search for Screenshots. The built-in algorithm may suggest that similar photos be deleted. It's also worth checking the deleted folder, as the files are stored there for 30 days and take up space.

For more thorough cleaning, you can use third-party applications from Google Play, specializing in finding duplicates, but often standard tools are enough. Regular viewing of the gallery and removing failed frames is the best prevention of memory shortage.

Specifics of cleaning messengers (Telegram, WhatsApp)

Messengers are the main garbage collectors on any Android device. Telegram, for example, by default caches all the media files viewed to open them faster when re-watched. Without setting up, this cache can grow to 10-20 GB.

In Telegram settings, go to Data and Memory → Memory Use. There you will see the Clear Telegram cache button. Moreover, you can set autodelete the cache, for example, store files only for 3 days or 1 week, which is the optimal setting to save space.

WhatsApp is similar, but files are stored in the file system. Go to chat settings and select Storage to see which dialogs take up the most space. Deleting large video files from correspondence can free up gigabytes.

💡

Turn on the “Removal of garbage” function in Telegram with a period of 3 days. This will automatically delete old cached files, freeing up space without your participation.

Resetting settings as a radical method

If no methods are working and the system continues to slow down and the space disappears mysteriously, a full factory reset may be required, a last resort that removes all data from the device, returning it to the "out of the box" state.

Before performing this procedure, be sure to back up important contacts, photos and documents in the Mi Cloud or Google Drive cloud. To reset, go to Settings → About Phone → Settings Reset → Erase all data.

⚠️ Warning: After resetting the device will be completely clean.Make sure you remember the password from your Mi Account and Google account, otherwise the phone may be blocked by the security system.

This method ensures that any software debris, viruses and system errors are removed, and once reset, the phone will work as fast as possible, but it will take time to reconfigure and install the applications.

💡

Full reset is the only way to remove system debris that cannot be removed through a file manager or standard cleaners.

Prevention and healthy habits

To avoid relapse into memory problems, develop good habits, check downloads regularly and delete unnecessary ones. APK-Disable auto-save photos from messengers to the gallery if you do not need this feature.

Use cloud storage to archive old photos and videos. Services like Google Photos allow you to free up space on your device by deleting images already stored in the cloud, which keeps internal memory free for the system to work.

• 📅 Check the “Downloads” folder once a week».
• 📅 Clean the heavy app cache once a month.
• 📅 Disable auto-update applications via mobile network.
• 📅 Use lightweight versions of applications (Lite) if memory is critically low.

Compliance with these simple rules will extend your Xiaomi life and ensure a stable operation without lags.Memory is a resource that requires management, and now you know how to do it correctly.
