Combining memory card and internal storage on Xiaomi Redmi: the complete guide

Why combine phone memory and microSD on Xiaomi Redmi?

Owners of Xiaomi Redmi smartphones often face a lack of internal memory, especially if the device from a budget line (for example, Redmi 9A or Redmi Note 10 with 32/64 GB on board). Even after cleaning the cache and removing unnecessary files, free space is melting before your eyes - the fault of app updates, high-resolution photos and messenger cache. The solution lies on the surface: combine the microSD card with internal storage, turning it into a full extension of the system.

But here's the catch: not all Redmi models support this feature out of the box. In fact, improper integration can lead to loss of data on the map or even malfunction of the phone. In this article, we will discuss how to safely expand memory, what nuances to consider when choosing a microSD, and what to do if the phone does not "see" the card after combining. And also - we will reveal the secret why some firmware (MIUI 12/13/14) the option is hidden, and how to return it.

Which Xiaomi Redmi models support memory integration?

Adoptable Storage, which allows microSD to be used as part of internal memory, is not available on all Xiaomi devices, depending on the Android version, MIUI firmware and hardware limitations.

• ✅ Supported by: Redmi Note 5/6/7/8/9/10/11, Redmi 9/9T/9A/9C, POCO X3/X4 and other models on Android 6.0+ s MIUI 8–14. The function can be hidden in the settings, but it can be activated manually.
• ❌ Not Supported: Android Go Devices (e.g. Redmi) A1), Some old models (Redmi) 4X, Redmi 5A) and smartphones MIUI For Russia (there is often disabled because of Google policy).
• ⚠️ Restrictions: On MIUI 12.5+ function may work unstable - after updating the system, the card sometimes "flys" and requires re-formatting.

To find out exactly if your Redmi supports the association, check:

1. Android version in Settings → About the phone.
2. The presence of the item Storage → Memory Map → Settings → Internal memory.
3. MicroSD model: It must be of grade 10 (UHS-I) or higher, or the system will refuse to merge.

Preparation of a memory card: what format to choose and how not to lose data

Before you combine a memory, a microSD card needs to be formatted -- not in the usual way, but with an internal storage, which erases all the data on it without any recovery!

⚠️ Note: If you have important files (photos, documents) on the map, copy them to your computer or cloud first. Once formatted in Adoptable Storage, the card will not be read on another device, it will become "linked" to your Redmi.

Requirements for the memory card:

If you use a card from an unknown manufacturer, check it for authenticity using the H2testw utility (for Windows) or SD Insight (Android). Counterfeits often have an understated write speed, which will lead to lags after combining.

Step-by-step: how to combine memory on Xiaomi Redmi

If your smartphone supports the function, follow this instruction, which takes 5-10 minutes, but requires careful attention.

1. Insert the memory card into the slot (on some Redmi models you need to turn off the phone before doing so).
2. Go to Settings. → Warehouse.
3. Tap on the name of your card (for example, SD-map: 64GB).
4. In the upper right corner, press on ⋮ → Storage settings.
5. Choose internal memory (or format as internal memory).
6. Confirm the action and wait for the formatting to be completed (the phone may restart).

After the merger:

• ✅ The map will be displayed as part of the internal memory in the settings.
• ✅ Applications can be transferred to it through Settings → Annexes → [Select an application] → Warehouse → Change.
• ❌ The card cannot be extracted without data loss – the system will give an error.

Memory integration via ADB: for advanced users

If the standard method does not work, you can try to activate Adoptable Storage via Android Debug Bridge (ADB).This method is suitable for models where the function is hidden by the manufacturer (for example, on MIUI for Russia).

• 🖥️ A computer with installed Xiaomi drivers and ADB.
• 📱 Included debugging by USB on the phone (Settings) → The phone. → Version. MIUI — Tap 7 times, then return to the additional → For developers → Debugging by USB).
• 🔌 Cable USB (preferably original).

Instructions:

1. Connect your phone to your PC and open the command line (Windows) or terminal (macOS/Linux).
2. Enter the command: adb shell sm list-disks Remember the disk ID (e.g., disk:179.64).
3. Format (replace disk:179.64 with your identifier): adb shell sm partition disk:179.64 private
4. Reboot the phone.

⚠️ Attention: Wrong ADB-If you're not sure what you're doing, you should go to the service center, and also note that once you format it, you can't use it on other devices without erasing it again.

💡

Before execution ADB-Create a recovery point in the TWRP (If you have custom Recovery installed, this will help you roll back changes when you fail.

Frequent problems and their solutions

Memory integration doesn't always go smoothly. Here are the typical mistakes and ways to fix them:

If the phone gets overheated or discharges quickly after the combination, check the card for errors using the SD Card Tester app.

Alternative ways to expand memory without combining

If your Redmi doesn’t support Adoptable Storage or you’re afraid of risking data, there are other options:

• 📁 Manual file transfer: Use a file manager (such as Mi File Manager) to move photos, videos and music to the map. Not all applications will work with external storage, but space will be freed up.
• ☁️ Cloud services: Google Photos (unlimited storage of compressed photos), Mi Cloud (5 GB free) or Yandex Drive (10 GB.
• 🔄 Memory optimization: In Settings → Warehouse → Cleaning can remove cache, duplicates and unnecessary files. Files by Google helps you find "garbage" automatically.
• 📱 USB-OTG drive: Connect the flash drive via an adapter. Some Redmi models (such as Note 10 Pro) support OTG "box".

For games and heavy applications (such as Genshin Impact or Call of Duty Mobile), it is better not to use a memory card – they require high read/write speeds, and even UHS-I cards may not cope, in such cases, it is optimal to buy a smartphone with a large amount of internal memory.

💡

Memory integration is suitable for storing photos, documents and lightweight applications, and 4K games and videos are better served by internal storage or the cloud.
