How to Clean Xiaomi Redmi Note 7 Phone: The Complete Guide

Xiaomi’s Redmi Note line of smartphones has earned a reputation for being reliable, but over time, even the most powerful processor can begin to experience difficulty processing tasks. If your Redmi Note 7 becomes noticeably slower to work, open applications for a long time or suddenly close programs, this is a sure sign that the accumulated digital “dirty” requires immediate removal. The MIUI operating system, based on Android, has the property of accumulating temporary files, remnants of remote applications and fragmented data, which over time slow down the device.

There are many ways to get your gadget back to speed, from simple manual cleaning to radical measures like a complete reset. In this article, we will detail how to safely and efficiently free up space, remove system debris and optimize RAM. You will learn how to use the built-in cleaner tools, find hidden files in messenger folders and properly prepare the device for deep cleaning to avoid losing important data.

Don't ignore the first signs of space shortage or interface slowdown, as this can lead to more serious problems with the file system. Competent cleaning of digital space will not only speed up work, but also prolong the life of the internal drive, preventing it from being worn out from constantly overwriting data. Let's start with basic methods that require no special skills and are available to every user right now.

Use of the built-in Security application

The first and most affordable tool to clean up the mess is the standard Security app, which is pre-installed in the default MIUI shell.This system module has access rights that allow it to delete the app cache, temporary installer files and remnants of banner ads that often remain after using free programs. Launching a deep clean through this tool is a safe step that will not affect your personal photos or contacts.

To get started, you need to open the app and select Cleanup, and then the system automatically scans the device for debris. The scanning process can take from a few seconds to a minute depending on the number of applications installed and the amount of data accumulated. Once you complete the analysis, you will see a list of file categories that can be deleted and the total amount of space released.

⚠️ Note: Before pressing the cleanup button, carefully review the list of found files, especially in the "Large Files" section, so as not to accidentally delete important documents or uploaded videos.

Inside the Cleanup app, Deep Cleanup is also available, which allows you to manage folder content in more detail, and you can find duplicate photos, old screenshots and unused ones. APK-Regular use of this tool at least once a week will help keep the Xiaomi Redmi Note 7 in good condition without the need for third-party software.

• 🧹 Click the "Clear" button to delete temporary system cache files.
• 📸 Check the Photos and Videos section for blurred photos or failed take.
• 📦 Delete. APK-Installation files that are no longer needed after installing the software.
• 🗑️ Clean the cart in the gallery, as photos deleted there still take up space.

💡

Set up automatic cleaning in the Security app so that the phone itself frees up space when a certain memory occupancy threshold is reached.

Manual cleaning through File Management

Automatic cleaners often cannot access specific messenger folders such as WhatsApp, Telegram or Viber, where a huge number of media files are stored. To effectively fight for free space, you need to manually check the contents of directories using the standard Explorer or Files. It is in the Android/media folders and root directories of social networks that gigabytes of viewed but unnecessary images and videos accumulate.

Special attention should be paid to the Download folder, where browsers and applications default to save all downloaded documents. Often users forget about old versions of price lists, restaurant menus or instructions that take up valuable megabytes. Also worth checking the DCIM folder, which may contain high-resolution videos that you have already transferred to your computer or to the cloud.

When manually cleaning, it is important to be careful not to delete system folders whose names you do not know. Deleting important system libraries can lead to incorrect display of the interface or malfunction of applications. If you are in doubt about the purpose of the file, you should first search for information about it on the Internet or skip this step.

To access hidden files and more detailed information about the occupied space, you can use the storage settings. Go to Settings → About Phone → Storage to see the visualization of occupied space. This will help you understand which categories of data eat up the most resources of your Redmi Note 7.

• 📂 Find the file. DCIM and check the.thumbnails subfolder for the presence of a thumbnail cache.
• 💬 Go to the messenger folders (for example, Telegram/Telegram Audio) and remove old music.
• 🌐 Clear the browser cache folder where temporary web page data is stored.
• 🎵 Check the Music and Recordings folder for old dictaphone records.

Cleaning the cache and application data

Each app you install creates its own cache, temporary data that speeds up its work, but can grow to giant sizes over time. For example, streaming services like YouTube or Netflix, as well as social networks like Instagram and Facebook, can take up several gigabytes of memory just by caching images and videos. Clearing this data does not delete your account, but resets the application settings to the original state.

To do this, go to Settings → Apps → All Apps. Select a memory-intensive app and click on the Clean button at the bottom of the screen. Here you will find two options: Clear cache and Clear everything (or Reset), the first option is secure and only deletes temporary files, the second will completely reset the app as if you had just installed it.

⚠️ Note: When you select the “Clear All” option, you will log out of your account in the app and you will have to re-enter your login and password, so make sure to remember the login details.

It is especially useful to clean up browser and mapping services that store offline maps and browsing history. Regularly cleaning the cache of heavy applications helps free up a significant amount of internal memory, which is critical for models with a small amount of internal storage.

Don’t forget to check the settings of the messengers themselves. Telegram, for example, has a built-in automatic cache clearing feature that can be activated in Settings → Data and Memory → Memory Use. You can also set a limit on the size of the cache so that it does not exceed a certain value, for example, 512 MB or 1 GB.

Removal of unused applications and widgets

One of the most effective ways to speed up the Xiaomi Redmi Note 7 is to remove programs you have stopped using. Every app you install, even if it's not running, takes up space in memory, can have background processes and receive updates, consuming traffic and battery power. Do a desktop and menu review, ruthlessly removing games you don't play and services you don't use.

The MIUI shell often comes with a preset set of programs that may not be needed by a particular user. Although it is difficult to remove system applications without root permissions, many of them can be simply disabled. To do this, go to the application settings and if the Delete button is inactive, try clicking Disable. This will hide the application and stop its processes, freeing up the system resources.

Also worth noting are live wallpapers and widgets on the home screen. Animated backgrounds and constantly updated news or weather widgets consume significant amounts of RAM and battery power, and replacing them with a static image and minimalist interface can significantly improve the responsiveness of a smartphone.

Analyze the frequency list you installed, and you can see in your battery settings or usage statistics which apps you last opened a month or a year ago, and if you don't need the software to run the system, removing it is a step toward a faster, cleaner phone.

Reset to factory settings (Hard Reset)

If the software cleaning and deletion of files did not work, and the phone continues to work slowly, the radical but most effective method is a complete factory reset, which completely removes all user data, settings and applications, returning the Redmi Note 7 to the "out of the box" state, which solves problems with software errors, viruses and deep conflicts in the system.

Before starting the procedure, it is critical to back up all the important data: you can use the Mi Cloud service, Google account or save files to your computer. Once reset, you can recover the data from the backup, but the files that did not fall into the backup will be lost forever.

To perform the reset via the menu, follow the Settings → About Phone → Reset. Select the “Erase All Data” option and confirm the action with a password to unlock the screen. The phone will reboot and begin the cleaning process, which may take some time. Do not interrupt the process or turn off the device until it fully starts.

⚠️ Warning: Make sure you remember the password of the Google and Mi Account account linked to the phone. Once reset, the system will require you to enter this data to confirm the owner's rights (protection against theft).

There is also an alternative reset via the Recovery menu, which is used if the phone is not loading normally, by turning off the device and clamping the Volume Up + Power button combination. In the volume button menu that appears, select Wipe Data and confirm the power button selection. This method is useful in more complex situations where access to system settings is not possible.

💡

A complete reset is a “nuclear option” that solves 99% of software problems, but requires a mandatory backup of the data beforehand.

Optimizing the system after cleaning

Once you have cleaned the Xiaomi Redmi Note 7 phone, it is important to set up the system correctly to keep the result for a long time.First of all, it is recommended to turn off or limit background activity for rarely used applications, this will prevent their uncontrolled resource consumption and accumulation of garbage in the future.

Turn on developer mode for more subtle animations. Go to Settings → About phone and 7 times quickly click on the version of MIUI. Then in the advanced settings, find the item "Scale of animation" and set the value 0.5x. This will visually speed up the interface, making the transitions between the screens more sharp and responsive.

Reboot your device regularly. Many users keep their smartphones on for weeks, which leads to an accumulation of errors in RAM. A brief reboot every 2-3 days helps the system to dump the accumulated debris and start processes again, which is especially important for devices with 3-4 GB of RAM.

• 🚀 Reduce the scale of animation in developer mode for visual acceleration.
• 🔒 Turn off auto-update apps over the mobile network, leaving only Wi-Fi.
• 🔋 Use energy saving mode to limit background activity.
• 🔄 Reboot your smartphone at least once a week to reset processes.
