How to clean up Xiaomi: speed up the smartphone and free up memory

Xiaomi’s smartphones, which run on MIUI shells and the new HyperOS, are famous for their functionality but can accumulate a significant number of temporary files over time. It’s a natural process of operating an Android device that leads to slowdowns, long launches of applications and a lack of free space for new photos. Users often wonder how to effectively clean Xiaomi without deleting important data and disrupting the system.

Deep cleaning isn't just about removing images from a gallery, it's a comprehensive approach to file system management that involves working with app cache, residual files from remote programs, and system logs. Proper memory maintenance allows you to extend the life of the drive and ensure stable operation of the processor even on models of past release. In this article, we will discuss safe optimization methods available to every owner.

Before embarking on radical measures such as a full reset, it’s worth trying less aggressive methods. Modern firmware versions offer built-in analysis tools that are often ignored by users in favor of third-party software. However, it’s native utilities that know the architecture of your phone’s file system best and can remove debris without risking damage to system partitions.

Use of the built-in Security application

Xiaomi

To get started, open the app and select Clean up. The system will automatically analyze and suggest removing files that are considered safe to delete. Pay attention to the "Big Files" and "Dublicates" section, which often hide forgotten videos or re-downloads of documents. This is a safe method for regular maintenance.

⚠️ Warning: Before mass removal of photos from the "Dublicates" section, carefully check their contents. The algorithm can find similar but different pictures are the same, and you risk losing important frames.

The built-in cleaner is constantly updated by developers. Recent versions of HyperOS add the ability to deep-clean messengers such as Telegram and WhatsApp without losing your correspondence history, allowing you to delete only media files, freeing up space, but saving text messages.

Use a built-in cleaner once a week to keep your memory from filling up critically, and regular prevention is more effective than cleaning a single overcrowded storage unit.

Manual cleaning of cache and application data

Social networks and instant messengers typically generate the most garbage. Apps like VK, Instagram or TikTok store a huge amount of temporary data to quickly load the tape. Over time, this cache inflates to tens of gigabytes, taking up precious space in the device's memory. Manual cleaning of each application allows you to control this process in more detail.

To do the cleaning, go to the Settings menu, then select the Apps and All Apps. Find the program you want (like YouTube) and click on it. Inside the app menu, you'll see the Clean or Storage button. Here, it's important to distinguish between two types of cleaning: Clear Cache and Clear All Data.

Cache cleanup is secure and only deletes temporary files, speeding up the application. Cleaning up all data returns the application to state immediately after installation, removing logins, passwords and settings. Use this feature with caution if you do not want to re-authorize in services.

  • πŸ“± Social media: Take up the most space due to uploaded images and videos.
  • πŸ›’ Marketplaces: Cache pictures of goods that can be safely removed.
  • 🎡 Streaming services: accumulate data of listened music and album covers.

Some system applications can also grow, such as Google Play services or system bootloader can accumulate error logs. Cleaning them often solves problems with interface freezes. However, you should not touch applications marked "System" if you are not sure about their purpose, as this can lead to unstable Android operation.

Storage analysis and search for hidden files

Often memory is occupied with files that the user does not even know exist, such as forgotten downloads from browsers, saved statuses from messengers or logs of system errors. It is recommended to use an integrated storage analyzer or open-source third-party utilities to identify such heavyweights.

In the phone settings menu, look for the About Phone or Warehouse section, and it will show you the visualization of the occupied space by category: apps, images, videos, documents. By clicking on the category, you can see a list of files sorted by size, which allows you to quickly find and delete, for example, a forgotten 4K movie that was downloaded a month ago.

Pay particular attention to the Download folder and hidden messenger folders. In Telegram, for example, media files can be stored in the memory of the device, even if you just viewed them in the channel. Set up auto-save or periodic manual check of the folder Android/media/org.telegram.messenger helps to keep the garbage under control.

File typeWhere to findIs it safe to remove?Recommended frequency
Cash browserSettings -> AppendicesYes.Once a week.
Downloads (Downloads)File managerSelectivelyOnce a month
Error logs (.log)folder MIUI/debug_logYes.If necessary,
Temperature files (.tmp)Folder /tmpYes.After the disruption

It's also worth checking the.thumbnails folder in the hidden sections of the gallery, which stores thumbnails of your photos for quick preview. If you have tens of thousands of photos, this folder can weigh several gigabytes. It can be cleaned, but the system will recreate it the next time you open the gallery.

Cleaning through Developer Mode and ADB

For advanced users who want to clean Xiaomi as deeply as possible, there are debugging tools. Connecting through ADB (Android Debug Bridge) allows you to remove system debris and cache that is not available through the usual interface. This method requires connecting to a computer and installing drivers, but gives you full control over the file system.

Before you start, you need to activate the developer mode. To do this, go to Settings -> About Phone and quickly click 7 times on the version number MIUI or HyperOS. After the message "You became a developer" go to advanced settings and enable USB Debugging. You may also need to enable USB Debugging (security settings).

adb shell pm clear com.android.browser

This command will completely clear the browser data. You can do the same with other packages. However, be extremely careful: deleting these system packages can lead to a bootloop. Always check the name of the package before performing the cleaning command.

⚠️ Attention: Use ADB A syntax error or the removal of a critical system process can render the phone inoperable, requiring flashing.

There are also graphical shells for ADB, such as Xiaomi ADB/Fastboot Tools, which simplify the process by safely removing pre-installed apps (bloatware) that cannot be removed by standard means, thereby freeing up the space and resources of the processor.

List of safe for removing system applications
Mi Video, Mi Music, Mi Browser, GetApps, Mi Pay (if not in use), Mi Cloud. Removing these components will not disrupt basic phone functions such as calls and SMS.

Removal of duplicates and large files

Duplication of files is a common problem when using a smartphone, which can be copies of photos saved from different messengers, or documents downloaded several times, and finding and deleting such copies is an effective way to quickly make room without losing relevant information.

Use file managers with duplicate search function. Many of them analyze not only file names, but also hash amounts, which allows you to find the same files even with different names. Be careful when deleting: sometimes different folders contain the same files, but one of them can be used by a particular program.

Video files deserve special attention. They take up the most space. Check the messenger folders, where the received videos are often automatically saved. Often there are commercials or unnecessary stickers that can be ruthlessly deleted. Also check the folder. DCIM/.thumbnails, previously mentioned.

  • πŸŽ₯ Videos: Take up the most space, check the folder "Video" and instant messengers.
  • πŸ“Έ Serial shooting: the gallery often remains hundreds of identical frames, leave only the best.
  • πŸ“‚ Archives: old ZIP and RAR archives that have been unpacked but not removed.

Regularly reviewing uploaded files helps keep things in order, and make a rule: browse the downloads pack once a month and delete the APK installation files that have already been used to install the apps.

Radical measures: Resetting to factory settings

If none of these methods worked and the phone continues to run slowly, it may have accumulated critical errors or fragmentation of the file system has become too large, in which case the most effective solution is a full reset to the factory settings (Hard Reset), which will return the device to the state "out of the box".

Before performing this procedure, be sure to back up all important data to your computer or to the Mi Cloud/Google Drive cloud. After resetting, it will be impossible to recover data without a backup. Make sure the phone is at least 50-60% charged.

To perform the reset, go to Settings -> About Phone -> Reset -> Erase all data. The system will warn you of the consequences. Once confirmed, the phone will restart and begin the cleanup process, which can take 10 to 30 minutes depending on the amount of memory.

⚠️ Warning: After resetting, you'll need to enter the password from the Google account and Mi Account that were previously linked to the phone. This is anti-theft protection. Forgotten passwords can block the device.

This method ensures that all viruses, hidden miners and system debris are removed, and often after such a reset, older smartphone models start to work as fast as they did on the day of purchase, the best solution before selling the device or transferring it to another user.

A complete reset is a last resort that solves 99% of software speed problems, but requires a mandatory data backup.

Prevention and healthy habits

So you don't have to clean your phone all the time, you have to develop good Android habits, and first of all, you have to control your app permissions and autoload, and many programs like to run on their own and hang in the background, consuming RAM.

Set up auto-cleaning in the standard Security app, and you can set a schedule where your phone will automatically clean the cache and close the background apps at a set time (e.g., at night) to keep the system on track without you being involved.

Also keep an eye out for system updates. Newer versions of MIUI and HyperOS often come with patches that optimize memory and fix resource leaks. Don't ignore update notifications, especially if they're marked as important.

  • 🚫 Turn off autoboot for rarely used apps in battery settings.
  • ☁️ Use cloud storage for photos and videos by enabling the β€œFree Space” function".
  • πŸ“΅ Remove unused apps that haven’t been used for more than a month.

Compliance with these simple rules will allow your Xiaomi to stay fast and responsive throughout its lifespan.Smartphone memory is a resource that requires management, and regular digital space hygiene works wonders.

Can I delete the Android/data folder?
The Android/data folder stores app data, including cache and downloaded files (offline maps, music, game levels). You can manually delete the contents of this folder through the file manager, but this will reset the settings of the relevant applications and lose offline content.
Why does the memory fill up quickly after cleaning?
This is normal system behavior. Applications create new temporary files to work with. If memory fills up too quickly (in a couple of days), check if any application is working in the background with a log error, or if the function of saving all media files from messengers in the gallery is included.
Is it safe to use the Play Market’s Cliner Apps?
Most third-party clinders (Clean Master and peers) provide minimal performance gains and are often themselves a source of advertising and data collection. Xiaomi and Android built-in tools are quite enough for maintenance. Third-party utilities can even slow down by constantly working in the background.
How to clean the DNS cache on Xiaomi?
To clear the DNS cache, you can go to the call menu and type ##4636## (does not work on all firmware), select Wi-Fi Information and click Wi-Fi Statistics, then Reset Statistics. Alternatively, the easiest way is to turn on and off Flight Mode or reboot the router and phone.
Does filling up memory affect the charging speed?
The memory filling does not directly affect the chemical reaction rate in the battery. However, if the memory is crammed, the system runs slower, the processor experiences a load during write/reading operations, which can lead to heating of the device. The heated phone, in turn, can reset the charging current for protection, which indirectly increases the charge time.
