How to effectively clean the memory on Xiaomi Redmi 7

Xiaomi’s Redmi 7 series has long been popular in the budget segment due to the balance between price and functionality. However, over time, users often face a lack of free space, which leads to a noticeable slowdown, long application launches and even sudden freezes. Android operating system in conjunction with the MIUI shell requires a certain amount of disk space for the correct functioning of background processes.

When embedded storage becomes overflowing, the device becomes unstable and some functions may become unavailable. Owners often wonder why memory is filled so quickly and where it is used. The answer lies in the accumulation of temporary files, messenger cache, residual data from remote programs and high-resolution media files.

In this article, we will take a look at all the available ways to optimize disk space: you will learn how to safely remove system debris, transfer data to a memory card and use hidden debugging tools for deep cleaning. A competent approach to file management will allow you to extend the life of your gadget without having to buy a new model.

Analysis of disk space

Before we start taking radical steps to delete files, we need to know exactly what takes up the lion's share of space. The MIUI tools that are built in provide some pretty informative statistics, but they don't always show the whole picture. We need to use a standard analyzer that visualizes the distribution of data by category.

Go to Settings, then select About Phone and click on Warehouse, and here you will see a color diagram showing apps, images, videos, audio and system files in different colors. Often, it turns out that the bulk of the work is not the installed games, but the social media cache or the forgotten high-resolution videos.

A system partition can take up a significant amount of memory, which is fine, but if it has swelled to an unthinkable size, it’s worth checking for large logs or residues after the update. Sometimes users forget about downloaded files from the browser that have been lying in the Download folder for years. You should also pay attention to the folder. DCIM, where the camera is stored.

• 📊 Visual Chart Helps You Quickly Find the Heaviest Categories of Files.
• 📂 The Downloads folder often contains.apk installation files that are no longer needed.
• 💬 Messengers like Telegram or WhatsApp can take up tens of gigabytes due to the auto-saving of media.

⚠️ Note: When analyzing storage, do not delete files from system folders with Latin names unless you are sure of their purpose.

Use of the built-in cleaning tool

The MIUI shell features a powerful built-in tool called Security, which includes a clean-up function, a first step that any user should take, as the algorithm scans the most common debris sites. The app automatically finds temporary files, remnants of deleted programs and advertising cache.

To start the process, open the Security app (green icon with a shield) and click on the Cleanup button. The system will quickly scan and prompt you to delete the files found. It is important to understand that standard cleaning does not affect deep system logs or the cache of heavy applications like YouTube or Instagram, unless you use advanced features.

After the initial scan, click on the Garbage icon to see the details, where you can select specific file types to delete. Regularly using this feature helps keep the system in good shape, but you shouldn't rely on it alone, as it often skips large files hidden deep in the file structure.

💡

Set up automatic cleaning in the Security app so that the phone deletes temporary files itself when a certain memory filling threshold is reached.

It's worth noting that once cleaned, the system can run faster, as resources are freed up to write new data, and the fragmentation of the file system is also reduced, which has a positive effect on read speed, but if the place ends up quickly again, the problem lies in the particular devourer application.

Cleaning the cache and application data

The most voracious consumers of memory in modern smartphones are social networks and instant messengers. Apps like Viber, Telegram and Instagram store every image and video they view into a local cache to upload them faster when they are re-watched. Over time, this cache can grow to several gigabytes, taking up precious space on Redmi 7.

To clear the cache of a particular application, go to Settings, select Apps, and click All Apps. Find the right program, such as YouTube, in the list. Inside the app menu, you will see two important buttons: Clear cache and Clear all data. The first one is secure and only deletes temporary files, the second one will reset the application to a state immediately after installation.

Using the Clear All Data feature will require re-authorization in the account, but this is often the only way to free up really much space. Messengers also have built-in memory management tools. For example, Telegram can set up automatic deletion of the cache after 3 days or a week, which eliminates the need to do it manually.

• 🗑️ Chrome or Mi Browser cache also takes up space, it can be cleared in the settings of the browser itself.
• 📸 Gallery can store deleted photos in the basket for up to 30 days, do not forget to clean it.
• 🔄 After cleaning the data of the navigators (Google Maps, Yandex Maps) will have to re-download offline maps.

⚠️ Warning: Clearing the Camera or Gallery app data won’t delete your photos, but will reset the default editing and filter settings.

Working with photos, videos and cloud storage

Multimedia files are the main content that the user creates and saves. Redmi 7 camera is able to take quality pictures, but high-resolution JPG files and 1080p video quickly eat up gigabytes. If you do not want to permanently delete memories, the best solution is to use cloud technology or migrate to an external medium.

Google Photos offers a "Free Space" feature that removes images and videos that have already been safely stored in the cloud from your device. To activate, open the app, click on your profile avatar and select the appropriate option. This is a safe way to return several gigabytes by saving access to the archive over the Internet.

The alternative is to use a microSD card. Xiaomi Redmi 7 has a separate slot for the card, which allows you to transfer all heavy files there. SD-This will prevent the internal memory from being filled in the future.

Removing unnecessary applications and APK-file

Often users install games for a one-time or try different utilities without forgetting to delete them, each app takes up space for the installation file, but also creates its own folders with data, and the system can remain installers.apk, which were used previously and are no longer needed.

You can use a file manager to find and delete these files, like standard Explorer from Xiaomi. Go to the "Applications" or "Installers" category to find all.apk files. Deletion is safe because the program is already installed (or the file is broken) and it is not necessary for the system to work.

It's also worth revising the list of installed games. 3D-Games can take up 2 to 5 GB of space. If you haven't played them in months, you'd better delete them and download them again if you need to. Progress data on many games is stored in the cloud (Google Play Games), so you won't lose any of the achievements.

💡

Regularly auditing installed applications once a month helps keep the system clean and prevents unnecessary services from running in the background.

Some MIUI system applications can be disabled if you don't use them, although you can't delete them without superuser rights. Disabling prevents background processes from updating and running, which also saves resources, although it doesn't free up much disk space.

Deep cleaning through debugging mode

For advanced users who want to make the most of their Redmi 7, there is a developer mode that hides tools for more detailed memory and process management, and activating this mode requires care, as changing the wrong settings can affect the stability of the work.

To turn on Developer Mode, go to Settings → About Phone and quickly click 7 times on MIUI Version. After the message “You became a developer” appears in the settings menu, a new section will appear Additional → For Developers. There you can find options to limit background processes, which indirectly affects the speed of work, but not the amount of memory.

A more effective method is to use ADB (Android Debug Bridge) via a computer. By connecting your phone over USB and enabling debugging, you can remove system debris that is not visible to the average user. The adb shell pm clear command allows you to completely clear the data of any application, even the system, without going into the settings menu.

adb shell pm list packages -3


adb shell pm clear com.android.chrome

Using ADB requires caution; typing the wrong command can lead to the removal of important system components, but for power users, it is a powerful tool for “reviving” old smartphones with little memory.

⚠️ Attention: Use of teams ADB To remove system applications can lead to a "bootloop" (cyclical reboot!
