Owners of Xiaomi, Redmi and POCO smartphones often face a lack of built-in storage, especially after installing several heavy games and social networks. MIUI and HyperOS are able to manage memory efficiently, but modern mobile applications take up gigabytes, quickly filling the available space.
Fortunately, many models support microSD card installation, which allows for more physical storage. However, the process of moving games has its own nuances depending on the version of the Android operating system and the manufacturer’s shell. In this article, we will discuss current transfer methods, workarounds for system constraints and recommendations for proper configuration.
It should be noted that not all applications support external drive for security and performance reasons. Developers often block this feature to ensure the stable operation of their products, since the read speed is very fast. SD-The cards are usually lower than the internal flash memory, but for many games and media, this method remains an effective solution.
Preparation of memory card and smartphone for work
Before you start transferring files, you need to properly prepare the external drive.Buy a memory card of a reputable brand with a speed class of at least Class 10 or UHS-I, as old or slow cards can cause "freezes" and long downloads in games.Put the card into the slot of your Xiaomi device before the characteristic click and wait for the notification of the connection of the new media.
The system will offer several uses: as a portable storage or as part of internal memory. For transferring games, it is best to choose formatting as a portable storage so that you can easily retrieve the card on other devices. If you choose to expand internal memory, the data will be encrypted and will become unavailable on other phones.
⚠️ Note: Formatting a memory card will completely destroy all data on it. Be sure to copy important photos and documents to your computer or to the cloud before starting the procedure.
After formatting, make sure that the full map volume is displayed in the settings. In some cases, you may need to reconnect or reboot the device to correctly determine all gigabytes of volume.
Standard method of transfer through Android settings
The easiest and safest way to move an app is to use the built-in functionality of the operating system, which works on most versions of Android, although the interface may vary slightly depending on the version of MIUI. Open the settings menu and find the section responsible for managing installed programs.
From the list of all apps, select the game you want to move, usually heavy projects like PUBG, Genshin Impact or Call of Duty. Click on the app name to enter the control menu, which displays information about version, battery usage and space.
- 📱 Go to Settings. → Annexes → All applications.
- 💾 Find the right game in the list and tap it.
- 🔄 Press the Warehouse or Memory button.
- 📤 Select the option to Change or Move to SD-card (if the button is active).
If the movement button is inactive (grey), the app developer has banned the installation on the external media, in which case it will not be possible to transfer the main part of the game using standard methods, and you will have to resort to alternative solutions, which will be discussed below. Successful transfer can take from a few seconds to several minutes depending on the file size.
Adoptable Storage (Advanced Memory)
Adoptable Storage allows the system to treat an external memory card as an integral part of internal storage, which means that the system will decide where to install new applications, automatically distributing the load between the internal memory and the internal memory. SD-On Xiaomi devices, this feature is often hidden by default, but it can be activated through special commands or developer menus.
To activate, you need to turn on USB debugging mode. Go to Settings → About Phone and quickly click on the MIUI build number seven times. After the message “You became a developer” appears, return to the main settings menu, select Advanced Settings → For developers and find the Default option to install applications on external media.
⚠️ Attention: Using a memory card as internal memory reduces its write life. Cheap cards can quickly fail when you work with system files and game cache.
After activating this option, when installing a new game, the system will prompt you to choose the installation site. However, it should be borne in mind that the speed of applications may decrease if the memory card does not have a high write speed. 3D-This can be a critical factor in causing image twitching.
If the standard menu does not allow access to the function, you can use the command via ADB (Android Debug Bridge), which requires connecting the phone to the computer and having basic knowledge of working with the command line, but gives full control over the memory partitions.
Cache and OBB data transfer for heavy gaming
Many modern games share an installation file (APK) and additional data (cache, graphics, sounds) that are stored in the OBB folder. Often it is the cache that takes up the lion's share of space, while the application itself weighs a little. By moving this particular folder, you can free up a significant amount of internal memory, even if the main body of the game is left inside.
To perform this operation, you will need a file manager with permission to access system folders, such as Total Commander or MT Manager. Xiaomi’s standard Explorer can restrict access to system directories on new versions of Android, so using third-party software is necessary.
- Set the game into internal memory and run it once so that it creates the folders it needs.
- Close the game completely through the menu of running applications.
- With the file manager, go to the Android/obb folder.
- Find a folder with the game name (e.g. com.pubg.imobile) and move it to SD-map.
- Create a symbolic link (Symlink) to the old place so that the system “thinks” that the files are left in place.
This method requires care, as a mistake in the path can cause the game to stop running. Symbolic links work only on devices with received Root rights, which is an important limitation for ordinary users. Without Root rights, you can simply move the folder, but the game may require you to re-download data at launch.
⚠️ Warning: Do not rename folders with the game cache. the system searches for them by the exact name of the package, and any change in the name will lead to an error in the download of resources.
Comparison of data storage methods on Xiaomi
The choice of memory management strategy depends on your goals: maximum performance or saving built-in space. The table below compares the main approaches to storing games on Xiaomi devices.
| Method | Speed of operation | Difficulty | Risks. |
|---|---|---|---|
| Internal memory. | Tall. | Low. | Fast filling |
| Application portability (standard) | Medium | Low. | Not all games support |
| Adoptable Storage | Medium/Low | Medium | Depreciation of the memory card |
| Cache transfer (Root) | Depends on the card. | Tall. | Possible launch errors |
As you can see from the table, embedded memory remains the fastest option. SD-Cards are a compromise that allows you to install more games, but potentially sacrificing the speed of their download and operation (2D, Strategies, card games, the difference in speed will be invisible.
For the heavy. 3D-Open-world projects are recommended to keep at least the minimum set of games in internal memory. FPS and fast loading of textures, which is critical for a comfortable game.
☑️ Pre-transfer check
Optimization of games from external storage
After transferring games to the memory card, it is important to properly configure the system to ensure stable operation. SD-The card may lead to a slow reading speed over time, and it is recommended to defragment (if the file manager supports) or simply check the card for errors.
It's also worth turning off automatic game updates over the mobile network if the memory card is slow. Updates can occur in the background and put additional strain on the memory controller, causing lags in other apps.Configure Google Play to upgrade only via Wi-Fi.
Use memory monitoring widgets to keep track of filling. On Xiaomi, the built-in optimizer can clean garbage, but it can ignore the cache on the external map. Regular manual check of Download and Temp folders on the memory card will help maintain order.
If you notice that the game has started to fly or slow down after transferring, try to return it to internal memory, which will help diagnose the problem: if the speed of the card is low, no software tricks will help to start heavy graphics smoothly.
