How to effectively clean the memory on Xiaomi Redmi Note 7

Xiaomi Redmi Note 7 remains a popular device even a few years after its release, but built-in storage of 32 or 64 GB is often lacking. MIUI operating system over time becomes overgrown with temporary files, and applications accumulate gigabytes of cache, which leads to a critical slowdown in the interface. When the storage indicator lights up red, the system begins to work unstable, and new applications cease to be installed.

Freeing up space requires a holistic approach, because a standard clean-all button for deep cleaning is usually not enough: you will need to analyze the structure of files, find hidden folders of garbage and properly configure the multimedia. In this article, we will discuss proven methods that will help return the device to its former performance without losing important data.

Analysis of storage occupancy through embedded tools

Before you start deleting files, you need to know exactly what is taking up space. There is a powerful built-in tool in the MIUI shell that users often ignore, preferring third-party utilities. The standard analyzer not only shows the amount of space occupied, but also breaks down the data into categories, allowing you to see the real “eaters” of gigabytes.

To start scanning, go to Settings → Memory. Here you will see a color diagram showing apps, images, videos and system files in different colors. System data often takes up a disproportionate amount of storage due to accumulated logs and residual files after updates. Click on any category to see the detail and remove the extra directly from this window.

Special attention should be paid to the “Other” section, which often hides cached messenger data, temporary browser files and remnants of remote games. If this category exceeds 5-10 GB, manual cleaning through the file manager is required, since the automatic cleaner can miss important but hidden directories.

💡

The built-in memory analyzer in MIUI works more accurately than third-party analogues, since it has access to system partitions closed to conventional applications.

Cleaning the cache of applications and system debris

The fastest way to free up a few gigabytes is to clear the app cache. Cache is temporary data that speeds up the launch of programs, but can over time inflate to inadequate sizes, especially social networks and video services that save the videos and images viewed for re-image.

You can use the standard Cleanup feature in the Security app regularly, but for deep cleaning, you better go to the settings of each heavy app separately. Go to Settings → Apps → All apps, select the desired program (for example, YouTube or Telegram) and click Memory. There will be a “Clear Cache” button that will delete temporary files without affecting your personal correspondence or logins.

• 🗑️ Telegram: often takes up more than 5 GB due to saved photos and videos from channels.
• 📸 Instagram: accumulates a huge amount of cache when watching tape and stories.
• 🌐 Chrome/Yandex: browsers store copies of visited pages to speed up loading.

There is also a hidden system cache that can be cleared through an engineering menu or special commands, but on the Redmi Note 7 it is safer to use the proven method of restarting in recovery mode.However, before doing so, make sure you delete all unnecessary files manually, as the automation may not reach the deep logs.

Working with multimedia and DCIM folder

The bulk of user data on the Xiaomi Redmi Note 7 is taken up by photos and videos. The camera of this smartphone is capable of shooting in high resolution, and one minute of video in 4K can take hundreds of megabytes. The DCIM folder is the standard storage for all images, and this is where you need to start the revision.

It is recommended to install automatic sync with the cloud service Google Photos or Xiaomi Cloud. After successfully uploading originals to the cloud, you can use the "Free Space" function, which will delete local copies of files, leaving them available for viewing over the Internet, which allows you to access the entire archive without taking up the physical memory of the device.

It's also worth checking the Thumbnails folder inside the DCIM directory, which stores thumbnails of photos for the gallery. Sometimes a.thumbnails file can grow to a few gigabytes if there are thousands of photos in the gallery, and it can be safely deleted, the system will automatically recreate it, but it's smaller when you open the gallery.

💡

Use the "Baskbasket" function in the gallery. Deleted photos often stay there for 30 days, continuing to occupy space. Clear the basket for final removal.

Removal of duplicates and heavy files

When you use your smartphone, you inevitably accumulate duplicate files in your memory, which can be the same photos, documents downloaded several times, or application installation files (APKs), which are difficult to find manually, so you should use specialized tools or a built-in MIUI file manager.

Open the Explorer app and look at the APK Files section, which stores installers for every application that has ever been downloaded, and once you install the program, these files are no longer needed, and you can delete them, and you can often find tens of megabytes of dead cargo that only slows down the indexation of the storage.

You can use third-party scanner apps to find duplicate photos, but be careful about accessing personal data. A safer method is to sort files by size in the explorer. Go to the root of internal memory, select Size Sort, and carefully examine the top of the list, often with forgotten videos or archives.

The table below will help you to find out which files can be deleted without risk to the system:

Use of the SD-memory-extension

The Redmi Note 7 is equipped with a hybrid slot that allows you to use a microSD memory card. This is an excellent solution for storing multimedia, although it does not allow you to fully expand the system partition for installing applications without root rights.

Once you have installed the memory card, you should format it as Portable Storage. In the storage settings, you can force all new photos and videos to an external medium. In the Camera app, click on the menu icon and select Save on. SD-map".

Many apps also allow you to change the way you store data in your internal settings, such as Spotify or Yandex.Music, you can specify that the cache of tracks should be stored on the memory card, which will free up gigabytes in the internal partition, leaving the system fast and responsive.

Cleaning messengers: WhatsApp and Telegram

Messengers are the leaders in the consumption of space on modern smartphones. WhatsApp and Telegram by default store all received media files in the memory of the device. If you have many active chats and groups, there can be more than 10-20 GB of data in a year.

WhatsApp has a built-in storage management feature. Go to Settings → Data and Storage → Storage Management. The system will show a chat list sorted by space, you can selectively delete large videos or simply clear the history of correspondence with a particular contact without deleting the entire chat.

Telegram works differently: it stores the cache on the server, but actively caches it on the device for quick access. In the application settings, go to Data and Memory → Memory Use. Here you can see the size of the cache and set up automatic deletion of files that have not been opened for more than 3 days or weeks. This is a “golden setting” for owners of Redmi Note 7.

• 📹 Remove automatically saved videos from the gallery in the privacy settings of messengers.
• 📁 Check the folder regularly WhatsApp/Media/WhatsApp Video through the conductor.
• ⚙️ Turn off autoload media in mobile traffic so you don’t accidentally clog up your memory.

⚠️ Note: Before deleting WhatsApp or Telegram folders through the file manager, make sure to back up the correspondence to the cloud of the corresponding service. Simply deleting files can lead to loss of message history.

Hidden folders and system debris

Some applications create hidden folders that start with a dot (like.cache or.temp). In standard Explorer mode, they don't show up. To see them, turn on the hidden files in the MIUI Explorer settings.

A special place is occupied by the folder MIUI It's in the internal storage, and it's often in the folder. debug_log, These are debugging logs that developers need to find bugs, but the average user doesn't need them.

It's also worth checking the Tencent folder if you're using Chinese versions of games or specific applications. There are often tails from remote programs. Be careful with the Android/obb folder, there's game data. If you delete files from there, games may stop running or require re-downloading resources.

Removing system logs from the folder MIUI/debug_log — The safest way to quickly free up space without affecting user data.

Radical measures: Resetting to factory settings

If none of the above methods yielded the desired result, and the memory on the Xiaomi Redmi Note 7 is filled inexplicably again, it is possible that the file system has accumulated errors, in which case the solution is a complete reset to factory settings (Hard Reset).

This procedure will completely clear the internal memory, returning the phone to the "out of the box" state. Before that, it is critical to make a full backup of all data to the computer or to the cloud, after resetting, the system will work as quickly as possible, and the fragmentation of files will disappear.

To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The device will restart and begin the cleanup process, which can take anywhere from 10 to 30 minutes. Don't interrupt the power to the phone at this point.

⚠️ Warning: Complete data cleanup is irreversible.Make sure you remember the password from your Mi Account and Google account, as after the reset, the phone will require them to be activated (anti-theft protection).
