How to transfer data to a memory card in Xiaomi smartphones: apps, photos and files

Transferring data to a memory card in Xiaomi smartphones is a challenge that users face when they lack internal storage. Despite the apparent simplicity, the process has nuances, ranging from the limitations of MIUI on porting applications to the peculiarities of formatting microSD as an internal drive. In this article, we will analyze all the current methods, from standard system tools to workarounds for Redmi models, POCO and the flagship Xiaomi 12/13/14 series.

It's important to understand that not all data can be transferred, for example, system applications and some user programs (especially those that require high performance) will remain in internal memory. SD-We'll also look at how to avoid common mistakes, from losing data to slowing down your phone after you've moved it.

Preparation: which memory card to choose for Xiaomi

Not every microSD is suitable for memory expansion in Xiaomi smartphones.The manufacturer recommends using cards of class UHS-I (U1 or U3) with a write speed of at least 10 MB / s. For models with support for microSDXC (for example, Redmi Note 11 Pro + or POCO X4 Pro) the maximum volume can reach 1 TB, but the best choice will be cards for 128-512 GB from proven brands:

• 🔹 SanDisk Ultra is a reliable option for everyday use (read speed up to 120 MB / s).
• 🔹 Samsung EVO Plus – optimized for Android, supports A2 (fast-loading).
• 🔹 Kingston Canvas Go! Plus is a budget alternative with water and shock protection.

Before buying, check the specifications of your Xiaomi model on the official website. For example, Redmi 10 supports cards up to 512 GB, and Xiaomi 13 Lite – only up to 256 GB. Also pay attention to the file system format: cards larger than 32 GB require exFAT or NTFS, which not all smartphones support out of the box.

⚠️ Attention: Class maps A1 or lower can significantly slow down the application after the transfer. SD games or heavy programs, choose cards with markings A2.

Method 1: Formatting the map as an internal storage

This method allows us to combine SD-It's a card with internal memory, and it's a single partition, and the advantage is that you can port most of the applications:

• 📛 The card will be encrypted and will not be able to be used in other devices without formatting.
• 🐢 The speed of the card depends on the class of the card (on the A1 applications can hang).
• 🔄 After the map is extracted, some of the data will become unavailable.

To set up the map as an internal storage:

1. Insert microSD into your smartphone and wait for identification.
2. Go to Settings → Memory → Memory Map.
3. Press Three dots (⋮) → Storage settings → Formatting as an internal.
4. Confirm the action and wait until it is completed (may take up to 10 minutes).

⚠️ Warning: After formatting, all data on the map will be deleted! Pre-copy important files to your computer.

After formatting, the system will prompt you to migrate data. Select Move now or do it manually later through Settings → Applications → App Selection → Storage → Change → Memory Map.

💡

Formatting as an internal storage is the only way to transfer system updates and some protected applications to the system. SD-map.

Method 2: Manual file transfer (photos, videos, documents)

If you want to make room for photos, music or documents, just move them to a map without formatting. This method does not affect the application, but it is safe and reversible.

1. Open the Files (or Explorer) application.
2. Go to the Internal Memory section and select a folder (e.g. DCIM for a photo).
3. Press and hold the files to highlight, then tap More (⋮) → Move it.
4. In the list of locations, select a Memory Map and confirm.

To speed up the process, use the packet mode:

• 📁 Select the entire folder (for example, Download) and transfer it completely.
• 🔍 Use sorting by size (⋮ → Sort by → Size to move the heaviest files first.

To automate the transfer of new files (such as photos from the camera), set up the default save to the card:

1. Open the camera. → Settings (⚙️) → Preservation site.
2. Select Memory Card.

💡

If photos are not displayed in the gallery after transferring, update the media base: go to Settings → About → About Phone → MIUI version and tap 7 times according to version. Then select Update Media Storage.

Method 3: Transfer applications to a memory card (with limitations)

V MIUI 12-14 transfer of applications to SD-The card is only available for a portion of the programs and requires the map to be formatted as an internal storage (see Method 1).Even then, some applications (e.g. WhatsApp, Google Play Services) will remain in internal memory:

1. Open Settings → Applications → Application Management.
2. Select an app (like Facebook or Spotify).
3. Slip the vault. → Change. → Memory map.

If the Change option is inactive, it means:

• 🚫 The app does not support portability (e.g. Xiaomi Community or Mi Fit).
• 🔒 The card is not formatted as an internal storage.
• 📱 The device does not support function (relevant for some models) POCO s UFS 3.1).

Use the restrictions to avoid the ADB-commands (requires PC and enabled debugging on the USB):

adb shell pm set-install-location 2

This command will force the system to install new applications on the default map.

⚠️ Note: Not all applications will work correctly after forced transfer through the ADB. Test the functionality after moving!

Method 4: Using third-party applications for portability

If standard MIUI tools don't work, use third-party utilities. The best options for Xiaomi are:

• 📱 AppMgr III (App 2 SD) — shows which applications can be transferred and suggests alternative methods (e.g., cache cleaning).
• 🗃️ Files by Google – a convenient file manager with the function “Free space” and analysis of unnecessary data.
• 🔄 SD Maid – removes debris and duplicates, helping to optimize the place without transferring.

Example of AppMgr III:

1. Install the app from Google Play.
2. Give permission to access the storage.
3. In the Move to SD section, select the apps to port.
4. For unbearable programs, use Force Move (requires root rights).

Note that many utilities require root access, which voids the Xiaomi warranty. Alternatively, use ADB (see Method 3) or cloud storage (Mi Cloud, Google Drive).

Errors in data transfer and their solutions

When working with memory cards in Xiaomi, users often face typical problems, and consider the most common and ways to eliminate them:

If the card is no longer defined after formatting as an internal storage:

1. Reboot the phone.
2. Remove and re-insert the map.
3. Check the card on another device (for example, on a PC through a card reader).
4. If the card is not readable, format it in FAT32 via your computer and repeat the procedure.

To diagnose card speed, use the A1 SD Bench app. If the write speed is below 10 MB/s, the card is not suitable for storing applications.

Optimization of work after data transfer

After transferring data to the memory card, monitor the performance of the device. Here are some tips for optimization:

• 🔋 Disable autosynchronization for applications stored on SD (So, for example, Google Photos or Dropbox, and that's going to reduce the load on the map.
• 🗑️ Regularly clear the cache of transferred applications through Settings → Annexes → Warehouse → Clear the cache.
• 🔄 Avoid working with multiple “heavy” apps on the map at the same time (e.g., games). + video editor).

To extend the service life of the card:

• 📉 Don’t fill it more than 80% – it reduces speed and increases wear and tear.
• 🔌 Remove the card only after Safe Extract (in Settings) → Memory).
• 🌡️ Avoid overheating – do not leave your phone in direct sunlight with a card inserted.

If the phone slows down after transferring the applications, return the critical programs (messengers, banking applications) to internal memory.

1. Go to Settings → Applications.
2. Select the app and tap the Storage → Change → Internal Memory.

💡

The optimal balance is to keep on SD-Media files and rarely used applications, and leave system programs and frequently run games in internal memory.
