How to check and free up memory Xiaomi Redmi 7A

Users of Xiaomi budget smartphones often face a lack of space to install new apps or save photos. Owners of the Redmi 7A model are no exception, since this gadget is initially equipped with a modest amount of internal storage. Understanding where exactly the precious resource is spent is the first step to optimize the device.

In the Android operating system, on the basis of which the shell works MIUI, There is a clear separation between memory (RAM) permanent (ROM). Confusion in these concepts often leads to users trying to clear the wrong partitions without getting the desired result. In this article, we will discuss in detail where to see the current information about the filling of disks and how to correctly interpret the data obtained.

Timely monitoring of storage capacity avoids a critical slowdown: When the space runs out, the smartphone starts to work in jerks, and some applications may stop running altogether. Regular monitoring of memory status is a basic skill that every Xiaomi owner needs.

Differences between RAM and ROM in Smartphone

Before you move on to specific cleanup actions, you need to clearly understand the technical difference between the two main types of memory installed in your device: RAM is used by the system to store temporary data of running applications and active processes. It is cleared automatically when you turn off your phone or force programs to stop.

By contrast, ROM is designed to store all your files for the long term: your operating system, installed games, photos, videos and documents, which is the type of memory that Redmi 7A users are most concerned about, as it is limited to 16 or 32 gigabytes, some of which are occupied by system files.

• 📱 RAM Impacts the speed of switching between open applications and multitasking.
• 💾 ROM Determines how many files and programs you can physically save on your device.
• ⚙️ The system partition is reserved for Android and not available for user files.

It is important to note that increasing the amount of RAM available by software methods is not possible, it is a hardware characteristic, but the management of occupied space in the ROM is in the hands of the user and requires periodic intervention to maintain performance.

⚠️ Warning: Do not attempt to delete files from system folders at the root of the storage if you are not sure of their purpose. MIUI cyclic-reset.

Checking the built-in storage through settings

The most reliable and detailed way to know what memory is occupied on the Xiaomi Redmi 7A is to use the built-in system menu, which displays the most accurate information, broken down into categories, which allows you to quickly identify the “eaters” of space.

You have to open the main settings menu and find the partition that's responsible for the device. In different versions of the MIUI shell, the name of this item may vary slightly, but the location logic remains the same. Following this path, you will get a complete picture of the state of your drive.

Go to Settings → About Phone → Storage. In some firmware versions, the Storage option may be immediately in the main settings list or in the Advanced Settings section. The screen will display a color diagram where each sector corresponds to a specific data type.

And you can look at the System sector, which is usually a large part of the volume available, and you can see applications, images, video, audio, etc., and you can click on any of the sectors and you can go to a detailed list of files or programs that are in that category.

This is where you'll see the actual amount of free memory available for use, and if the bar on the indicator is red, it's a signal that you need to audit your files urgently.

Use of the "Security" application

Each Xiaomi smartphone has a proprietary Security app preinstalled, which includes a powerful tool for analyzing and cleaning memory, a method that often proves more convenient for the average user than deep immersion in system settings, as it offers automated scripts.

Run the Security app and select Cleanup. The system automatically scans the device for junk files, app cache, and large unused files. The process takes only a few seconds and produces results in megabytes that can be freed up.

You will be asked to remove the debris you find after scanning, but be careful: sometimes important files, such as saved documents from messengers, fall into the category of junk. Always check the contents before confirming the deletion if you are not sure of the origin of the files.

Additionally, there is an "App Management" feature on this menu that shows how much space specific programs and their data occupy, which is especially useful for finding heavy games or social networks that have grown to giant sizes due to accumulated cache.

• 🧹 Cleaning removes temporary files and cache.
• 📦 Application management shows the weight of each program.
• 📁 Large File Analysis Helps You Find Forgotten Videos and Archives.

Using Xiaomi’s regular tool is preferable to installing third-party “cliners”, which often consume resources and show intrusive advertising. MIUI.

Memory analysis through file manager

For those who prefer manual control, the built-in Explorer (File Manager) provides detailed statistics, which allows you to see the real structure of folders and understand which directories have swelled to obscene sizes.

Open Explorer and go to the Analysis tab (or click on the folder icon, then select the location analyzer) and the data is presented as a handy diagram where you can visually estimate the proportions of space with different types of content.

Click on the Documents or Apps sector to see a file list sorted by size. This is the most efficient way to find forgotten files that can take up gigabytes of space. Often users find old WhatsApp backups or downloaded movies here.

💡

Notice the.thumbnails folder in the hidden system folders, which stores thumbnails of your photos and videos, which can grow to several gigabytes over time, and can be safely deleted.

The file manager also has a date-based sorting, which helps you quickly find files that haven't been opened in months, and removing this digital ballast is the fastest way to get back space on the Redmi 7A.

Remember that deleting files through the Explorer is the final action. Unlike a shopping cart in a computer, it is extremely difficult to recover data deleted in this way on a smartphone without special software, so double-check the selection before cleaning.

Hidden reserves: cache and application data

A significant part of the memory on Xiaomi is often occupied by application data that is not visible when you normally browse the gallery. Social networks such as Telegram, Viber or WhatsApp tend to accumulate media files and cache in their internal folders, ignoring standard cleaning rules.

To get to those hidden reserves, you need to go to Settings → Applications → All Apps. Select the “heavy” app from the list and click on Memory. Here you will see the division by the size of the application itself, the amount of data and the cache size.

Clearing the cache is safe and will not cause personal data such as correspondence or logins to be lost. However, the Clear Data (or Reset) button will return the application to state immediately after installation by deleting all accounts and settings. Use this feature with caution only if you want to completely reinstall the program without deleting it.

⚠️ Before clearing the data of messengers, be sure to back up the correspondence in the cloud storage, otherwise you will lose the entire message history irrevocably.

Special attention should be paid to video and streaming applications that cache video for fast download. On devices with a small amount of memory, such as Redmi 7A, such cache can take up to 2-3 GB, which is a significant fraction of the total volume.

Optimization with Cloud Services

When the device’s physical memory is running out, the logical solution is to move data to the cloud. The Xiaomi ecosystem is home to Mi Cloud, which allows you to synchronize contacts, messages, notes and, most importantly, a gallery.

By enabling gallery sync, you can activate the Free Space function, and once the photos and videos are successfully uploaded to the server, they will be deleted from the phone's memory, but remain available for viewing through the cloud, allowing you to store thousands of images without taking up a single byte on the device.

Alternatively, Google Photos or Yandex.Disk, which also offer automatic uploading and cleaning of local copies, can be used to help the owner of Redmi 7A, using the cloud is actually a way to virtualize memory.

• ☁️ Mi Cloud is deeply integrated and does not require installation.
• 📸 Google Photos offers smart search and great compression without loss of quality.
• 📂 File sharing is suitable for storing archival documents that are rarely used.

When using mobile traffic, make sure that the synchronization settings are limited to “Wi-Fi only” so as not to consume the entire data packet.

Radical measures: reset to factory settings

If neither cache clearing nor file deletion helps and the phone continues to signal a space shortage, the last proven method remains - a full reset.This procedure will return the Xiaomi Redmi 7A to the state it was in on the day of purchase, completely freeing up the user's memory partition.

Before performing this operation, it is critical to create a full backup of all important data, as in the process all contacts, photos, apps and settings will be deleted, and reset can be done through the Recovery menu or through system settings.

Settings → About the phone → Reset settings → Erase all data

Once you reboot, you'll get a clean system with maximum free memory, and it's also a great way to get rid of hidden system bugs and accumulated software debris that isn't removed by standard cleaning methods.

💡

A full reset is a last resort, but it guarantees a return of up to 100% free user space and often speeds up the performance of an old smartphone.
