Smartphones of the Redmi 6line released by the company Xiaomistill remain popular due to their reliability and availability, but owners often face a lack of built-in storage. The operating system MIUI over time becomes overgrown with temporary files, which leads to a slowdown of the interface and the inability to install new applications. Understanding how to properly free up space becomes critical to extending the life of the device.
In this article we will analyze in detail all available methods for optimizing space, from standard tools to advanced techniques for working with system partitions. You will learn which files can be deleted without risk to the system, and which are best left alone so as not to disrupt the stability of the gadget. A competent approach to memory management will allow your smartphone work faster.
Analyzing storage capacity and searching for hidden files
Before taking radical measures, you need to determine exactly what is taking up precious gigabytes. The built-in storage analyzer in the shell MIUI provides a detailed map of memory usage, but it does not always show the largest hidden folders. Users are often surprised to find that free space disappears for no apparent reason, but the problem lies in the messenger cache or system logs.
To get the full picture, it is recommended to use third-party visualization utilities or built-in analysis tools. Pay attention to the "Other" section in the memory settings, which is often ignored, but can take up up to 30% of the total space. This is where the remains of deleted applications and temporary update files are hidden.
- 🔍 Use the built-in analyzer in the “Settings” → “Memory” menu for an initial assessment.
- 📂 Check the folder
Android/datawhere cached data of games and applications is stored. - 🗑️ Look for files with the extension
.logand.tmpthat can be safely deleted. - 📸 Separately check the messenger folders Telegram and WhatsApp, which are often duplicated media files.
⚠️ Attention: When manually cleaning a folder
Androidbe extremely careful. Deleting system files may lead to incorrect operation of applications that require authorization.
It is important to understand that standard analysis tools may not display the real size of some system processes that are disguised as service data. If you plan to use a third-party file manager, make sure that it has the necessary permissions to access all sections of the file system of your device.
Using the built-in Cleanup application and its nuances
The shell MIUI is equipped with a pre-installed tool "Security", which includes the "Cleaning" module. This tool is designed to quickly remove junk files, but its capabilities are often underestimated or, on the contrary, relied on. The scanner's algorithms are tuned to look for obvious temporary files, but it rarely touches the application's deep cache.
Running a deep clean through this application is a good first step, but not a panacea. The system will prompt you to delete files larger than 50 KB that have not been used for a long time. However, it is worth remembering that smart cleaning may deem unnecessary files that you plan to use in the near future, for example, temporary documents from browsers.
For more efficient work, it is recommended to manually expand the scanning parameters in the Security application settings. There you can set more aggressive thresholds to find duplicate photos and large video files. It is also worth activating the function of automatically clearing the cache when a certain fullness threshold is reached.
- 🚀 Run “Cleanup” regularly to prevent the accumulation of garbage.
- ⚙️ Configure scanning settings to search for duplicate photos and videos.
- 📉 Disable auto-upload unnecessary applications in the background.
You should not rely solely on automatic scripts, as they are not able to assess the importance of specific files for the user. Manually checking scan results before confirming deletion is a golden rule that will protect you from losing important data. Automation good, but control is necessary.
Clearing the cache of applications and social networks
The most voracious consumers of memory Xiaomi Redmi 6 traditionally are social networks and instant messengers. Applications like VK, Instagram and Telegram store huge amounts of data to speed up work by creating giant caches. Over time, the size of such a cache can reach several gigabytes, taking up the lion's share of the available space.
Clearing the cache of each application individually through the settings is a labor-intensive but effective process. Unlike deleting data, clearing the cache does not affect your logins, passwords and correspondence, deleting only temporary files. However, in some cases, for example in Telegram, it is better to use the built-in memory management tools of the application itself.
☑️ Checking messengers
For social networks, there is a nuance: after clearing the cache, the application can download images and videos again the next time you view the feed, wasting traffic. Therefore, it is recommended to carry out this procedure when you are connected to a Wi-Fi network, or do it before an important event, when the phone needs to work as quickly as possible.
| Application | Where the cache is located | Deletion security | Impact on operation |
|---|---|---|---|
| Telegram | Settings → Data and memory | High | Reload media |
| Google Chrome | Settings → Privacy | High | Reset authorization to sites |
| YouTube | Settings → General | High | Deletes offline video |
| Settings → Data and storage | Medium | Can delete media from chats |
It is important to distinguish between the concepts of “Clear cache” and “Erase data”. The second option will completely reset the application to its state immediately after installation, deleting all your accounts and settings. Be careful when choosing an action in the application management menu so as not to lose progress in games or correspondence.
Managing photos, videos and cloud services
Multimedia content is the main reason for lack of space on most smartphones. The cameras of modern phones, even such Redmi 6, take high-quality pictures that take up a significant amount of space. Video in resolution 1080p can “eat up” hundreds of megabytes per minute of recording, quickly filling the internal memory.
The optimal solution is to use cloud storage, such as Google Photos or Yandex.Disk. These services allow you to upload original photos to the cloud and automatically delete them from your device, leaving only the thumbnails. This creates the illusion of having all the photos on the phone, but they are physically stored on servers.
How to set up auto-delete in Google Photos
Go to the settings of the Google Photos application, select "Free up space." The system will offer to delete from the device those photos and videos that have already been securely stored in the cloud. This is a safe operation if you are confident in the availability of your account.
If using clouds is impossible due to lack of Internet or paid tariffs, you will have to resort to manual sorting. Deleting blurry photos, screenshots, and duplicates can free up up to 20% of your space. It's also worth checking the Trash folder in the gallery, as deleted files are often stored there for another 30 days.
- ☁️ Set up synchronization with the cloud in high quality to save space.
- 🗑️ Empty the Trash folder in the gallery and file manager regularly.
- 📹 Transfer long videos to your computer or external hard drive.
⚠️ Attention: Before bulk deleting photos, make sure they are actually copied to a safe location. Restoring deleted files without a backup is Android extremely difficult.
Working with an SD memory card and transferring applications
The model Xiaomi Redmi 6 supports installation of memory cards of format microSD, which is a great way to expand storage. However, simply inserting the card is not enough - it must be configured correctly. Operating system Android allows you to use the card as portable storage or as part of the internal memory.
When you format the card as internal storage (Adoptable Storage), the system encrypts it, and it becomes an integral part of the phone. This allows you to transfer applications and their data to it, but makes the card unreadable on other devices without formatting. This is an important decisionwhich cannot be taken lightly.
Settings → Storage → SD card → Settings → Format as internal memoryIf the card is used as portable storage, It can only transfer media files and documents, but not applications (with rare exceptions). For maximum efficiency, it is recommended to store all heavy files on the card, leaving the internal memory for a fast system and active applications.
Use memory cards with a speed class of at least Class 10 or UHS-I. Slow cards can cause interface lags and problems with video recording, even if the phone supports them.
It is worth considering that the speed of a memory card is always lower than the speed of the built-in storage. Moving too many active apps to the SD card can cause the overall performance of your smartphone to deteriorate. The balance between volume and speed is the key to successful optimization.
Removing system junk and unnecessary services
Firmware MIUI often contains pre-installed applications that the user never uses. Not only do they take up space, but they can also consume resources in the background. Removing or disabling such services is an advanced cleaning method that requires caution.
Some system applications cannot be removed using standard means, but they can be “frozen” or removed via ADB (Android Debug Bridge) from the computer. This allows you to get rid of intrusive services Xiaomi or Googlethat are not critical for the operation of the basic functions of the phone.
⚠️ Attention: Removing system components via ADB may lead to unstable system operation or cyclic reboots. Always check the purpose of the package before deleting it on the Internet.
For the average user, it is safest to use the “Disable” function in application settings. This will hide the application from the menu and prevent it from launching, freeing up RAM, although it will not take up all the disk space. This is a compromise, but a safe option.
- 🚫 Disable unnecessary system applications through the settings menu.
- 💻 Use ADB only if you are sure of the purpose of the package being removed.
- 🔄 Regularly check the list of installed applications for duplicates.
Particular attention should be paid to the folder MIUI at the root of the internal memory, where error logs and crash reports can accumulate. Files with the extension .log in this directory can be deleted if you do not plan to send reports to developers to diagnose problems.
Comprehensive cleaning includes not only deleting photos, but also working with the cache, system logs and disabling unused services.
Frequently asked questions (FAQ)
Is it possible to delete the Android folder completely?
No, you absolutely cannot delete the entire folder Android . It stores application data, cache and configuration files. Deleting this folder will reset all applications to factory settings, loss of game progress, and possible system errors. You can clear the contents of a folder cache inside it, but the structure itself should not be touched.
Why does the memory quickly fill up again after cleaning?
This is normal behavior for modern smartphones. Applications constantly create new temporary files, browser caches grow with each visit to sites, and instant messengers load new images. It is recommended to carry out preventive cleaning once every 1-2 weeks to keep the system in good shape.
Is it safe to use third-party cleaning applications?
Most popular cleaners are safe, but often they themselves are a source of advertising and unnecessary load on the battery. Built-in tools MIUI usually sufficient for everyday tasks. Third-party utilities should be used only for specific tasks, for example, searching for duplicate files.
How to clear memory if the phone does not turn on?
If the phone does not boot due to full memory, try entering mode Recovery (usually by holding down the power button and volume up). There you can try to reset the settings (Wipe Data), but this will delete all data. In some cases, connecting to a computer in MTP mode helps if the drivers allow you to open the file system.
