Owners of the popular budget model Xiaomi Redmi 8 often face a critical shortage of built-in storage.In an era when mobile applications weigh gigabytes, the standard 32 or 64 GB becomes catastrophically small for installing modern modern storage. 3D-The system starts to work slower, and messages about filling up memory appear at the most inopportune time, preventing the full use of the device.
Fortunately, the Android architecture allows you to expand the available space with an external drive, and transferring data to a microSD card is an effective way to free up the system partition and return the smartphone to its previous performance, but this process has its own technical nuances that must be considered for all programs to work correctly.
In this article, we will discuss how to transfer the game to the Xiaomi Redmi 8 SD card using both standard system tools and more advanced methods. You will learn about the risks associated with formatting external media, and understand why some applications fail to work after moving.
Why memory is overflowing and how it affects the Redmi 8
Redmi’s smartphones, including the eighth model, often feature eMMCs, which have limited write and read speeds. When space runs out, the MIUI operating system begins to have difficulty creating temporary files and cache, leading to noticeable delays when launching applications and even accidental departures from games.
The main users of space are not only the installation files of games, but also their cache, updates, and multimedia files created during use. Heavy projects like PUBG Mobile or Call of Duty can take up more than 5 GB of disk space, which is a significant part of the total memory of a budget device.
Ignoring the problem of overcrowded storage can lead to more serious consequences than just interface brakes: the system may refuse to update, WhatsApp will stop working correctly, and in the worst case, the device will enter a cyclical reboot, so monitoring the free space should become a regular habit.
⚠️ Attention: Continuous work with the completed 95-100% internal drive significantly reduces the life of its service due to the wear of memory cells.
Understanding the structure of memory helps you manage space more efficiently. Not all files are equally important, and some can be safely deleted or moved without compromising system functionality. Analyzing what is eating gigabytes is the first step to optimizing.
Preparing the SD card for use as an extension
Before you start transferring data, you need to properly prepare the external media. Not every memory card is suitable for installing heavy games and working as an extension of the system. For Xiaomi Redmi 8, it is recommended to use cards of the standard Class 10 or higher, marked U1 or U3, which guarantees sufficient write speed.
Insert the card into the slot and wait for the system to notify. If the card has been used in other devices, it is better to format it to avoid file system errors. Remember that formatting will destroy all data, so pre-copy important files to your computer or to the cloud storage.
After the physical installation, go to the storage settings, and here you will see the information about the occupied and vacant space, the system will suggest using the card as a portable storage or as internal memory, and for our purposes, the second option is more interesting, but it requires caution.
⚠️ Note: After formatting the card for internal memory, it is encrypted and will not be read on other devices without a complete reset.
The quality of the memory card directly affects the speed of loading levels in games, cheap media can become a “narrow neck”, which will load textures with a delay, and the game will slow down even on a powerful processor, the savings on the memory card in this case are not practical.
Standard method of transfer through Android settings
Android provides a built-in mechanism for moving applications, which is the most secure and doesn’t require superuser rights, but it’s worth noting that not all games support full portability, as developers can block this feature.
To start the procedure, open the settings menu and find the "Applications" section. From the list of installed programs, select the game you want to move. If transfer is possible, the "Move" button will be active. Otherwise, the system will tell you that changing the installation location is not available.
The process of moving can take from a few seconds to several minutes, depending on the size of the game and the speed of the memory card. During the operation, do not remove the card or restart the device so as not to damage the data files. Once completed, the application shortcut will remain on the desktop, but the physical files will be on an external medium.
☑️ Pre-transfer check
Sometimes the game can run unstable after the transfer, in such cases it is worth trying to uninstall the application completely and install it again, choosing the memory card as the default place when installing, if such an option is offered by the system or installer.
Use Adoptable Storage feature on Xiaomi
Adoptable Storage allows you to convert SD-So, unlike standard porting, the system combines spaces, and the applications "think" they're installed on the built-in storage. MIUI This function is often hidden, but it can be activated.
Activation requires access to a developer menu or use of special commands via ADB (Android Debug Bridge), a more complex method that requires connecting a smartphone to a computer. sm set-force-adoptable true command forces the system to consider the card as internal memory when formatting.
Once you have enabled the function and formatted the map, you can install any game directly to the external media, and the system will distribute the load and files itself, ideal for devices with a small amount of internal memory, such as the basic version of Redmi 8.
Risks of using Adoptable Storage
It should be borne in mind that after activating this mode, the memory card will work only with this particular smartphone. Move it to another phone or connect it to a computer to read files without formatting will not work.
Transferring games and large files manually
Many heavy games store the main resources (textures, models, sounds) in a separate cache folder, usually located along the path of Android/obb or Android/data.
For manual transfer, use a built-in file manager or a third-party application, such as Total Commander or ES Explorer. Find a folder with game data (often called the developer, such as com.tencent.ig for PUBG) and move it to the root of the memory card or to a specially created directory.
Once you move, start the game. If it doesn't find the files, create a symbolic link (root access required) or use the "Associate folders" feature in advanced file managers, which will make the system think that the files are in the old place, although physically they will be on the map.
| Type of data | Default location | Where to move | Risk of data loss |
|---|---|---|---|
| APK file (installer) | Internal memory (hidden) | No need to be moved. | Low. |
| Cash games (OBB) | Android/obb/ | SD card / Android/obb/ | Medium. |
| Preservation of games | Android/data/ | Cloud/SD card | High-pitched |
| Downloads and media | Download / DCIM | SD card | Low. |
This approach requires care. An error in the folder name or path can cause the game to stop running or require re-downloading resources. Always back up before manually tampering with the system folders.
Frequent problems and methods of their solution
In the process of memory optimization, users may encounter various errors: a smartphone may not see the card, games may fly out immediately after launch, or the system may report a read error, most often due to file system incompatibility or damage to sectors of the card.
If the game stopped running after the transfer, try clearing its cache through the application settings. In some cases, re-installing the game with a memory card already inserted helps. Make sure the card is formatted in the exFAT or FAT32 file system, which is best supported by Android.
💡
Use SD Maid to find residual files from remote games, which often take up space but do not provide any benefit to the system.
Slowing down your phone after transferring games indicates a slow card speed, so it makes sense to return the most demanding read projects to internal memory, and move less active applications or media files to the map.
⚠️ Warning: If the memory card suddenly stops being defined, don't rush to format it again. Try first to check the contacts in the slot and wipe them with alcohol.
Regular defragmentation is not required for memory cards in Android, as the file system works differently than in Windows. However, periodic checking for errors through the computer will be a useful prevention.
Optimizing the performance of games after the transfer
After successfully migrating games to the SD card, it's important to make sure they work correctly. Run each displaced project and check the loading times of levels. If you notice artifacts or long downloads, it might be worth experimenting with the graphics settings inside the game itself.
Decreased texture and shadow quality can compensate for the slower read speed from the memory card. In MIUI settings, it is also worth turning off window animations and transitions for general interface acceleration, which is especially true with full memory.
Remember to check for updates periodically. When updating, the system may try to upload new files to internal memory, even if the main part of the game is on the map, watch for notifications of space shortages, and repeat the cleaning or transfer procedure if necessary.
💡
Ideal configuration: System and heavy online games in internal memory, single project cache and media files on fast SD-map.
Competent memory management allows you to extend the life of Xiaomi Redmi 8 for several years. Using external drives correctly, you get a device experience comparable to the more expensive models with 128 GB and more internal memory.
