How to Clean Xiaomi Redmi Note 7: A Complete Guide to Optimization

Xiaomi Redmi Note 7 is a legendary device that, even years after its release, remains popular for its value for money. However, over time, any, even the most powerful gadget starts to work slower. It is an inevitable process: temporary files accumulate, app caches grow, and the free space on the internal drive is reduced to critical values. If you notice that your phone is long respond to commands or suddenly closes applications, it’s time to do a general cleaning.

In this article, we will not only look at the standard cleaning methods available to each user through the settings menu, but also deeper ways to free up space. You will learn how to safely remove system debris, which folders can be touched without risk to the Android operating system, and how to properly use the built-in MIUI tools. A competent approach to data storage will extend the life of your device and return it to its former sharpness.

Before you start deleting files, it's important to understand that cleaning isn't just about removing photos, it's about optimizing your CPU and RAM. The system cache can take up gigabytes of space that don't do any good for the user, but only slow down the performance. Let's take a step-by-step look at how to get your Redmi Note 7 to its perfect state.

Use of the built-in "Security" application

The easiest and safest way to start servicing a device is to use the manufacturer's standard tools, and the MIUI shell has Security, which combines the functions of an antivirus, a garbage cleaner and a task manager, and launch it, and the system automatically scans for malware and temporary files.

Once you've finished your initial analysis, you'll see the Clean button, and clicking on it will remove the system cache, the residual files of the deleted applications, and the temporary browser data. But don't stop there. There's a Cleanup section inside the app where you can see in detail what exactly is taking up space, and it often hides large video files from messengers or duplicate photos.

Importantly, the Acceleration feature in the same application helps free up RAM, which forcibly closes the background processes that can consume CPU resources, and using this tool regularly, at least once a week, helps keep the interface running smoothly.

💡

Don't use third-party accelerators from the Play Market - they often consume more resources themselves than they save.The built-in MIUI tool is more than enough to work efficiently.

Be careful with automatic cleaning if you have important unsaved data in the clipboard or temporary folders of work applications.While the risk is minimal, it is better to double-check the list of files proposed for deletion, especially if you are working with documents on your phone.

Manually clean memory through storage settings

If the automatic tools didn't work, you need to move to manual storage management, which requires more care, but allows you to free up much more space. → Memory. Here you'll see a detailed diagram of the distribution of space, divided into categories: applications, images, video, audio and so on.

The largest category is usually "Apps." When you click on this, you get a list of all installed programs, sorted by size. Often it turns out that social networks or navigators have grown to several gigabytes because of accumulated maps and media files. Once you go into the properties of a particular application, you can select "Clear Cache."

⚠️ Warning: Don't confuse the Clear Cache and Erase Data buttons. The second option will completely reset the app to factory status, removing your logins, passwords and game progress without the ability to restore it.

Special attention should be paid to the Downloads folder, which often downloads APK installation files that are no longer needed, or documents that you opened once, deleting these files safely and instantly frees up space, and check the gallery basket - deleted photos can be stored there for another 30 days, taking up precious gigabytes.

For advanced users, you can view hidden files through the file manager. In MIUI Explorer, enable the display of hidden files in the settings, which will find and remove empty folders from long-deleted games or error logs that take up space but are not visible during normal browsing.

Cleaning up garbage in messengers and social networks

The leaders in memory consumption in modern smartphones are instant messengers. Telegram, WhatsApp and Viber have one thing in common: they automatically store every received photo, video and voice message in the memory of the device, over time, this data turns into giant archives that slow down the work of the Redmi Note 7.

In Telegram, the cleanup is done most efficiently through internal settings. Go to Settings → Data and memory → Memory Use. Here you will see the "Storage Media" slider. Set a value at, for example, 3 days or 1 week. Also click "Clear Cache" button. Importantly, this action will not delete correspondence, the files will simply be re-uploaded from the cloud if necessary, freeing up space on the disk.

WhatsApp is more complicated because it's less aggressive in cleaning itself up, so you have to go into chat settings and turn off auto-save in the gallery, and for manual cleaning, go to the storage management inside the app, and you'll see a list of chats sorted by volume, and it often turns out that 80 percent of the space is occupied by videos from group chats that you don't even care about.

• 📱 Disable autoload media in the settings of each messenger so that new files do not automatically accumulate.
• 🗑️ Regularly check the Documents section in messengers – heavy files that can be deleted often get there.
• 📹 Watch videos in chat rooms before deleting: sometimes in group conversations, duplicate videos are transmitted.
• 💾 Use the Chat Archivation feature before cleaning if you are afraid of losing important correspondence history.

Social networks like VK or Facebook also cache images and videos viewed for faster downloads. In the settings of these apps, find the App or Cache section and clean up. This won't delete your accounts, but will make the images load again the next time you view them, which is an acceptable fee for freeing up space.

Removing System Garbage and Unnecessary Applications

Xiaomi smartphones often come with a pre-installed set of apps that not all users find useful, called bloatware. Some can be removed in the standard way, others require a deeper approach. Removing unnecessary system services that you don't use (such as Mi Video, Mi Music, if you don't use them) can reduce the load on RAM.

To remove system applications that are not removed through the normal interface, you can use the USB debugging method and the ADB tool (Android Debug Bridge) on your computer. This requires caution. You need to turn on the developer mode by clicking 7 times on the build number in the About Phone section and activate debugging over USB.

adb shell pm uninstall -k --user 0 com.miui.videoplayer

This command will remove the standard Xiaomi video player for the current user without affecting the system partition, which is safe. However, before using such commands, it is strongly recommended to find the exact name of the package of the removed application and make sure that it is not critical for the system to work. Removing Google Play Services or System Components MIUI It can lead to unstable work.

If you are not confident and do not want to risk the stability of the system, it is better to limit yourself to removing only those applications that allow you to do this through the standard settings menu. On Redmi Note 7, the system partition is protected, and simply deleting user data will not damage the firmware, but removing system packages through ADB requires accuracy.

Analysis of large files and duplicates

Often, it's not hundreds of small files that fill the space, but a few forgotten archives or movies. The MIUI file manager has a file sorting function by size. Go to Files and select Size Sort. You might be surprised to find a forgotten high-resolution movie or a photo archive that you shared with yourself over Bluetooth a few years ago.

You also need to look at duplicates. When you use instant messengers often and save statuses from Instagram or WhatsApp, you can see copies of the same images in the gallery. There are special applications for finding duplicates, but you can do with built-in tools. The Xiaomi gallery has algorithms that group similar photos, which helps you manually select the best shots and remove blurred or repetitive ones.

Remember the Bluetooth folder at the root of the internal memory, and it automatically stores all files that you've received through bluetooth, and often it contains old business cards, melodies, or pictures that you've taken back años that you don't need anymore, and deleting them is the fastest way to get a free space.

Resetting to factory settings as a radical method

If no cleaning methods have worked and the smartphone continues to work 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 phone to the state of “store-like”.

Before you do this, make sure to make a full backup of all important data. Reset will delete absolutely everything: contacts, SMS, photos, apps and their settings. It is recommended to use Google cloud service or the built-in Mi Mobile app to create a backup to your computer or the cloud.

To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The phone will reboot and start the cleanup process, which can take anywhere from 5 to 15 minutes. Once turned on, you get a clean system that tends to run much faster.

⚠️ Warning: Make sure the battery level is at least 50-60% Interrupting the process due to discharge can damage the software part of the phone.

After reset, take your time to install all the apps at once. Try using a clean phone for a while. Often it turns out that the brakes were caused by one particular application that you didn't even know was happening. Install the programs gradually, tracking the impact of each on performance.

💡

Full reset (Hard Reset) is the most powerful tool to combat software errors and accumulated debris, which is guaranteed to return the smartphone factory speed.
