How to clean up memory on the phone Xiaomi Redmi Note 7

Xiaomi Redmi Note 7, released in early 2019, is still a popular device due to its excellent price-performance ratio. However, like any gadget with 32 or 64 gigabytes of internal memory, it eventually begins to suffer from a lack of free space. When the system partition is crowded, the phone runs slower, applications can fly out, and new photos or system updates stop loading.

Cleaning up your drive is not just about removing old images, it's about taking a comprehensive approach to managing your MIUI file system. In this article, we'll look at all the effective ways to do things from standard tools to advanced junk file management. You'll learn how to safely free up gigabytes without removing important system components.

The first thing you need to do is audit what exactly takes up space, and users often don't even realize that instant messengers or streaming cache can eat up to 10-15 gigabytes of data, and a good cleanup will make your Redmi Note 7 agile.

Use of the built-in "Security" application

MIUI has a powerful optimization tool that is often underrated, which allows you to quickly delete temporary files left over from various programs, without having to download third-party software, just look for the Security icon on your desktop or in the Tools folder.

Launch the app and click on the Cleanup button. The system will automatically scan the internal storage and prompt you to remove the garbage. However, don't rush to agree immediately with everything. Click on the Cleanup button to see the detailed content. Here you will find temporary files, remnants of deleted ones. APK-packages and ad cache.

⚠️ Attention: Large Files may appear in the Cleanup section. Be very careful: your personal videos or archives may be located here. Always check the contents of the folder before deleting so that you do not lose important data.

And on top of that, there's Deep Clean, which analyzes files in more detail, finding duplicate photos and unused installation packages, and using this tool regularly is the safest way to keep your system in order without risking damage to your firmware.

Storage analysis through Android settings

The regular memory analyzer in Redmi Note 7 provides more in-depth statistics than just garbage cleaning. To get into this section, go to Settings → Memory. Here you will see a color diagram showing the distribution of space between applications, images, videos and system files.

Click on Apps to sort them by size. Often it turns out that social networks like Telegram or VK take up several gigabytes because of the accumulated cache. You can click on each "heavy" application and select the "Clear Cache" option, which is safe and will not delete your correspondence or accounts.

Special attention should be paid to the section "Other". MIUI This is often where files that the system can't classify come in, if the partition has grown to an unimaginable size (more than that). 10-15 GB), you may need to manually check through the file manager or reset settings.

Also in this section, you can see the volume of the system. On the Redmi Note 7, with Android updates and the MIUI shell, the system partition can take anywhere from 8 to 12 gigabytes. That's normal, and you can't clean it without flashing it.

Cleaning messengers: Telegram, WhatsApp, Viber

Messengers are the main memory eaters on modern smartphones, automatically storing all received photos, videos and voice messages in the memory of the device, and Telegram is made worse by the fact that cache can grow indefinitely if limits are not set.

Consider Telegram. Go to Settings → Data and Memory → Memory Use. Here you will see the amount of cache you have occupied. Click on Clear Telegram cache. Don't worry, your chats and media files won't disappear forever - they're stored on the server and will be downloaded again when you browse. You can also install automatic cleanup here, for example, every 3 days.

WhatsApp cleans up differently. Open a chat, click on the name of a contact or group, then select Media, Links and Documents. You can select files by type (like video only) and delete them en masse. After that, remember to go to Settings → Chats → Chat History and clear the database if it takes up too much space.

Removal of duplicates and large files

Over the years, hundreds of screenshots, identical photos, and forgotten downloads have been accumulated in folders, and a built-in MIUI file manager or third-party snails like Files by Google will help you find them.

Use the duplicate search function. The algorithm will find copies of files, even if they have different names. This is especially true for those who often take screenshots of correspondence or documents. Deleting duplicates is a quick way to free up several hundred megabytes.

Separately, check the Download folder. This is where browsers and apps drop installation files. APK, PDF-Documents and temporary archives. Often you can find old versions of applications that have been installed and updated for a long time.

Large video files are also worth revising. Videos at 1080p or 4K quickly eat up memory. If you don't have to store them on your phone, move them to your computer or to cloud storage.

💡

Set up automatic uploading of photos to Google Photos or Yandex.Disk, followed by removal from the device. This frees up space "on the fly" without your participation.

Working with the folder "Other" and system garbage

The category “Other” in the storage of Xiaomi Redmi Note 7 often causes panic among users, which gets files that the system cannot identify: remnants of deleted applications, error logs, temporary update files and cache of streaming services (YouTube, Netflix, Spotify).

To clear this partition, it's often not enough to just click the "delete" button. You need to manually go to the root folder of internal memory through the file manager. Look for folders with the names of remote games or applications. It's also worth checking the Android/data and Android/obb folders, but you need to be extremely careful here.

⚠️ Attention: In the folder Android/obb The hard game cache files are stored. If you delete the contents of this folder, the games will stop running and require you to re-upload the data.

Another source of debris is the MIUI folder inside the memory root, which can contain old themes, sounds and voice recorder logs, and files with the.log or.tmp extension can be deleted safely.

If the Other takes up a critical amount of space and doesn't shrink after cleaning, it's possible that the system has an indexing failure, which is where the phone restarts or, in extreme cases, factory resets help.

Use of cloud storage and memory cards

Redmi Note 7 does not support microSD cards, so owners of 32-gigabyte versions are especially important to use cloud technology. Services like Google Drive, Yandex.Disk or the Mi Cloud allow you to transfer photos and videos to the Internet.

Set up automatic gallery sync. Once the photos are uploaded to the cloud, use the "Free Space" function in the cloud service application, which will delete local copies of files, leaving them in the gallery, and when you click on the thumbnail, the photo will be downloaded from the Internet.

Also consider using USB-OTG. By buying a USB adapter, you can plug in flash drives and transfer archives of movies and documents to them, which turns your smartphone into a mobile office with virtually unlimited storage.

💡

The lack of a memory card slot in the Redmi Note 7 makes cloud services and regular manual cleaning the only ways to manage space long-term.

Radical methods: Resetting and flashing

If none of the above methods worked, and the phone continues to signal a lack of space, it may be that the file system is damaged or has accumulated errors, in which case a complete reset helps.

Before you do this, make sure to make a full backup of your data. Go to Settings → About Phone → Settings Reset → Erase all data. The phone will go back out of the box and all user files will be deleted. This is guaranteed to free up all available memory.

For advanced users, custom firmware (such as LineageOS or Pixel Experience) can be installed, and they lack Xiaomi’s heavy pre-installed software and take up less space in the system partition, but this requires unlocking the bootloader and carries risks.
