Despite its popularity and reliability, Redmi 7s inevitably face a lack of space over time. Android users often find that after a year of heavy usage, the phone is slowing down and space-short notifications are increasing, because modern apps take up much more space and multimedia files are piling up at an alarming rate.
Cleaning internal memory is not just about removing photos, it's a complex system maintenance process. The right approach to managing storage allows you to extend the life of your gadget and avoid critical errors when installing important updates. In this article, we will discuss in detail all available optimization methods, from simple built-in tools to advanced settings.
Before we start taking drastic measures, we need to understand what exactly takes up precious gigabytes. System debris, app cache and forgotten downloads often make up the lion’s share of the occupied volume, and ignoring these factors can lead to the fact that the device will cease to function correctly or even refuse to run basic programs.
Analysis of vault occupancy
The first step to freeing up space is accurate diagnostics. The MIUI system installed on the Xiaomi Redmi 7 provides users with convenient tools for visualizing data. However, standard graphics do not always show the full picture, so it is important to know where to look. Often users are surprised to find that the Other folder occupies a disproportionate amount of space.
To start, you should go to the settings menu and select the memory option, and here you will see a color diagram that shows apps, images, videos and system files in different colors. On Redmi 7, the Other sector is often inflated by the cache of messengers like Telegram or WhatsApp, which the system does not always correctly classify.
Don't ignore the app section. It often weighs 50MB, but it's grown to just a few gigabytes. This is especially true for social networks and navigators who store maps and media locally, and checking this section regularly reveals space eaters you might not even know existed.
It is also important to consider that some of the memory is reserved for the needs of the operating system and is not available to the user. On a model with 32 GB of internal memory, usually about 20-22 GB is available for use. This is normal for the Android architecture, and attempts to “free” the system partition without flashing will not lead to anything.
⚠️ Warning: When analyzing memory, be careful with files marked as system. Deleting unknown files from root directories can lead to unstable phone performance or data loss.
Use of the built-in MIUI cleaner
The safest and fastest way to delete temporary files is to use the regular Security app, which is pre-installed on all Xiaomi smartphones and optimized for the MIUI shell, which scans the device for residual files, cache and advertising without affecting important user data.
Launch the app and press the Clean button, and the system will analyze and suggest that you delete files that it considers safe to delete, usually residues from remote applications, temporary browser files and a cache of sketches, which takes no more than a minute, but can free up from 100 MB to 1 GB of space, which is critical for performance.
But remember, the built-in cleaner isn't always deep, it works by algorithms and can skip some types of garbage to keep programs running, so it's recommended that you use it as a preventative, not as the only solution to the problem of overcrowded memory.
☑️ Daily cleaning through the Security app
For deeper cleaning, there are additional tools inside the Security app. For example, the Garbage Cleanup feature has advanced settings where you can select specific file types to delete, and it is also useful to regularly check the Accelerate section, which closes the background processes consuming RAM, which indirectly affects the speed of storage.
Cache and application data management
The biggest memory consumers on Redmi 7 are traditionally social networks and instant messengers. Telegram, VK, Instagram and WhatsApp store a huge number of media files that are automatically uploaded to chats. Over time, these files take up gigabytes, even if you have already viewed them and you do not need them.
To make room, you need to go to the settings of each heavy application separately. From the Apps menu, find the program you want, go to Memory, and select Clear Cache. This action is safe: it will delete temporary files, but save your logins, passwords, and correspondence. If you choose Clear All Data, the application will return to state immediately after installation, and you will have to log in again.
Special attention should be paid to settings for autoloading media in instant messengers, Telegram and WhatsApp can prevent automatic saving of photos and videos to the gallery, which will prevent duplicate files: they will be available in chat, but will not take up space in the general storage of the phone, this is one of the most effective ways to save space in the long term.
The Secret Android Folder
Remember browsers. If you are actively using the Internet, page cache, cookies and saved pages can take hundreds of megabytes. Regularly cleaning the history and data of sites in the browser settings (Chrome, Mi Browser) is a mandatory procedure to maintain the cleanliness of the system.
Working with multimedia and files
Photos and videos are the main content that the user creates, and it is this that most often fills the memory of the Xiaomi Redmi 7. The smartphone camera takes high-quality pictures that take up a considerable volume, especially if high-resolution recording is enabled. The standard gallery often stores deleted photos in the cart for 30 days, continuing to occupy space.
It is recommended to regularly check the folder “Recently deleted” and clean it. In addition, it is worth analyzing the folder “Screenshots” and “Downloads”, which often accumulate unnecessary images, checks, memes and temporary files from the Internet. Using cloud services such as Google Photos or Yandex.Disk, you can store the originals in the cloud, leaving only compressed copies on the phone or deleting them altogether.
File management is convenient with built-in Explorer or third-party solutions like Total Commander, which allow you to sort files by size and find the heaviest objects, and often forget old video lessons, downloaded TV series or APK installation files that are no longer needed.
| Type of file | Where to find | Recommendation |
|---|---|---|
| Photos and videos | DCIM, Pictures | Move it to the cloud or PC |
| Documents | Download, Documents | Remove old PDFs and APKs |
| Messengers | Android/media, Tencent | Set up auto-removal of media |
| Maps. | Android/data (Navitel, Yandex) | Remove offline maps of regions |
💡
Use the “Clear Similars” feature in the MIUI Gallery. It automatically finds duplicate photos and suggests removing extra copies, which is especially convenient after a serial shoot.
Removing Unused Applications and Games
On Redmi 7, with its limited internal storage, every megabyte counts. Apps you haven't used in more than a month are worth uninstalling. Modern programs are often large and their background processes can slow down the system.
Go to the app settings and sort them by size or date of last use. You'll be surprised how many apps are installed "just in case" or forgotten after a single use. Games are particularly space-intensive: a single project can weigh 2-3 GB, which is a significant fraction of a phone's memory.
You should also look at Xiaomi system applications that you can disable, and although you can't remove them completely without root permissions, shutting them down will prevent them from being updated and running in the background, but be careful: disabling important system components can disrupt the interface.
⚠️ Warning: Before uninstalling the app, make sure it is not a system component needed for other programs to run.Removing system packages can cause the phone to reboot cyclically.
If you rarely need an app to remove it, consider Lite versions, and apps like Facebook Lite, VK Lite or Google Go take up less space and consume less resources, which is ideal for Redmi 7.
Expanding memory by means of SD-map
One of the main advantages of the Redmi 7 is that it has a separate microSD card slot, which is the best solution to the problem of space shortage. You can transfer all photos, videos, music and documents to an external map, freeing up internal memory solely for installing applications and operating the system.
In the storage settings, you can select the memory card as the default recording location for the camera and voice recorder. Many applications also allow you to specify the path to save files in their settings. SD-This prevents the internal section from being filled with media content.
However, it is worth remembering that the memory card is slower than internal flash memory. It is not recommended to transfer the applications themselves to the map, especially heavy games, as this can lead to long downloads and slowdowns. The memory card is ideal for static files, but not for dynamic data programs.
💡
Using a fast Class 10 or UHS-I memory card is a prerequisite for comfortable multimedia work on Redmi 7. Cheap cards can slow down video recording.
Check the status of the memory card regularly. SD-Periodic formatting of the card (pre-saving data on the PC) helps to keep it in working order and avoid errors "file damaged».
