How to increase memory Xiaomi Redmi 7: the complete guide

Owners of the popular budget model Redmi 7 often face a lack of free space to install new applications or save photos. Internal storage of 32 or 64 GB quickly fills up with system files, messenger cache and heavy games. When the device’s RAM is limited to 2 or 3 gigabytes, and the internal is crammed to the full, the smartphone starts to work slowly, interface freezes and spontaneous reboots of applications appear.

There are several proven ways to free up precious gigabytes without having to flash your device or buy a new gadget. In this article, we’ll look at effective methods for cleaning up system debris, transferring data to a memory card and using external drives via the USB interface. Proper file system management will extend the life of your Xiaomi smartphone and speed up its operation.

Before we start taking any drastic measures, we need to analyze the current state of storage, and understanding what exactly occupies space is the first step to optimizing, and then we'll go into detail each step of cleaning and expanding your device.

Storage occupancy analysis and system settings

The first step in the battle for space is detailed diagnostics. Standard MIUI tools provide enough information, but often hide details. You have to go to the settings and find the About Phone section, and then select Warehouse, and it shows the big picture: how much is occupied by the system, applications, images and other files.

But the built-in analyzer doesn't always show the actual cache volume of individual applications. For more in-depth analysis, you should use third-party utilities or built-in Explorer. Look at the Download and DCIM folder, where forgotten high-resolution video files often accumulate, and much of the space is taken up by data from messengers such as WhatsApp and Telegram.

⚠️ Note: When analyzing storage, do not delete files from system folders with names like Android, MIUI Or config, if you're not sure what they're supposed to do, and that could cause the operating system to malfunction.

It's important to understand the difference between space and memory. The file system also reserves space for correct operation. If less than 10% of the total volume is free, the data write speed can critically drop.

💡

The system analyzer shows only general categories, so for accurate cleaning, you need to go to the settings of each heavy application separately.

Cleaning the cache and removing system debris

The fastest way to free up space is to clean up cached data. Cache is a temporary file that speeds up the launch of applications, but grows to giant sizes over time. Xiaomi smartphones have a built-in Security app that allows you to clean up garbage. However, manual control gives better results.

For deep cleaning, go to Settings → Apps → All apps. Sort the list by size of space occupied. Select the heaviest programs (social networks, browsers) and click Clear → Clear cache. Don't confuse it with the Clean All button, which will reset the app to factory settings and delete your logins.

• 🗑️ Delete old update files MIUI, which often remain the root of internal memory after system update.
• 📱 Check the folders of messengers: in Telegram, the cache can be cleared through the settings of the application itself, saving the history of correspondence.
• 🌐 Clear up your download history in Chrome or standard browser MIUI, Deleting temporary Internet files.

Sometimes users forget about the shopping cart in the gallery, and the deleted photos and videos don't disappear completely, but move to the "Recently Deleted" album, which is stored for 30 days. Be sure to empty this folder to make room.

Using a MicroSD Memory Card to Expand

The Redmi 7 is equipped with a hybrid slot, which means that you can install a microSD card up to 256 GB (officially) and even more in practice. This is the most effective way to solve the problem of space shortage for media files.

Once the card is installed, the system will suggest using it as Portable Storage or Internal Memory, the former being preferred for this model, as the write speed to budget memory cards may be lower than the speed of the built-in flash drive, which will lead to interface brakes, in the latter case the card is formatted and encrypted, becoming unavailable to other devices without resetting.

Settings → Storage → SD-card → Format

After setting up, you need to transfer all heavy files manually or automatically. In the camera settings, specify saving photos and videos immediately to the memory card.

⚠️ Warning: Do not remove the memory card while your smartphone is running or recording video.This can cause file spreadsheet damage and data loss.

To transfer existing files, use a file manager. Select folders DCIM, Pictures, Music and Download, select Move and point the way to SD-Map. Modern versions. MIUI They can offer file transfer when internal memory is overflowing.

Comparison of methods of memory expansion

The choice of method depends on your goals: whether you need a place to install games or just to store a photo archive. Below is a comparative table of available methods that will help determine the optimal strategy for your Xiaomi Redmi 7.

As you can see from the table, physical expansion with a memory card is the most tangible and consistent result, and software methods are good as a supportive measure, but they don't solve the problem radically.

It is worth noting that installing apps on a memory card in modern versions of Android is limited to developers, so the main emphasis should be on storing media content and documents on an external medium.

Connecting external drives through OTG

If even 256 GB on a memory card is not enough for you, technology will come to the rescue. USB On-The-Go: Redmi 7 supports external connectivity USB-scaling-up OTG. This makes the phone a powerful tool for handling large amounts of data without the speed loss typical of cheap memory cards.

To connect, you'll need an adapter from micro-USB (or USB-C, depending on the board revision, although Redmi 7 uses micro-USB) to a standard USB. Connecting a flash drive or external hard drive will see a notification in the curtain. MIUI file manager automatically recognizes the device and lets you copy files.

This method is ideal for watching high-quality movies or working with heavy documents that do not need to be stored on the phone all the time, and once the drive is finished, you can turn off the drive, freeing up the port for charging.

• 💾 Use the exFAT file system or FAT32 for maximum compatibility with Android.
• 🔋 When connecting powerful external hard drives, active power may be required, as current from the phone may not be enough.
• 📂 Create separate folders for projects on an external disk so as not to get confused in files.

⚠️ Attention: Before disconnection USB-Make sure to click “Safe Retrieval” in notifications or in the storage menu, otherwise files may get corrupted.

Cloud storage as an alternative to local memory

In the era of high-speed internet, cloud storage is becoming the standard, with services like Google Photos, Yandex.Disk, or Mi Cloud freeing up gigabytes on a device by storing copies of files on remote servers, especially for Xiaomi owners with a small amount of internal memory.

Set up automatic gallery sync. Once you create a copy in the cloud, use the Free Space feature, which will remove the originals from the device, leaving only thumbnails, and if you want to view the photo in full resolution, it will quickly download from the Internet.

For documents and work files, use Google Drive or similar services. Many document editing apps support direct cloud work without requiring the file to be saved to the phone's internal memory.

💡

Turn on the “Save space” function in Google Photos – it will automatically delete photos from the device, copies of which are already saved in the cloud in their original quality.

The downside of this method is that it depends on the quality of the Internet connection, so if you're in a bad reception zone, it can be difficult to access your files, so it's smarter to combine cloud storage with a physical memory card.
