Combining the memory of the phone and SD-Xiaomi Redmi cards: a complete guide with nuances

Why combine the memory of the phone and SD-map?

Xiaomi Redmi smartphone owners often face a shortage of internal memory, especially if the device is purchased with a minimum storage capacity (16 or 32 GB). Even after cleaning the cache and removing unnecessary files, the free space is melting away before our eyes - the fault is due to app updates, high-resolution photos and social media cache. SD-The system perceives the memory card as part of the internal storage, allowing you to install applications and save data directly to it.

But it's not that simple. The Adoptable Storage technology that underlies this process has limitations. First, not all Redmi models support this feature out of the box, depending on the version. MIUI And secondly, once combined, the memory card cannot be retrieved and used in another device without formatting. SD-The card may be lower than the internal memory, especially if the card is Class 10 or lower.

In this article, we will discuss:

• 📱 What Xiaomi Redmi models support memory integration (list with version specifications) MIUI)
• 🔧 Step-by-step instructions taking into account the nuances for different firmware
• ⚠️ Risks and pitfalls that are not covered in official manuals
• 🔄 Alternative ways to expand memory if unification is not possible

Which Xiaomi Redmi models support memory integration?

The Adoptable Storage feature was officially available in Android 6.0 Marshmallow and later, but Xiaomi often blocks it in its firmware. MIUI — Below is a compatibility table for popular Redmi devices (relevant to the following: MIUI 12–14):

If your model is not on the list, check the support as follows:

1. Put it in. SD-phone-card.
2. Go to Settings. → Warehouse.
3. Tap by name. SD-map → Three dots (menu) → Storage settings.
4. If you have the option to format as internal memory, the function is supported.

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

Before starting the procedure, make a backup of all data from the phone and SD-Combining the memory will result in a full formatting of the card, and cancelling the operation will only return it to its original state after re-formatting.

The instructions are relevant to MIUI 12-14 on global firmware. If you have a Chinese version (China) ROM), Some menu items may be different.

Step 1: Formatting SD-maps as internal memory

1. Put it in. SD-card to the smartphone if the notification appears SD-Map found, tap Configure.
2. Go to Settings. → Warehouse.
3. Choose yours. SD-map → Three dots (menu) → Storage settings → Formatting as an internal.
4. Read the consequences warning and confirm the action by clicking on Erase and format.

Step 2: Transfer of data to SD-map

Once formatted, the system will suggest transferring some of the data (photos, videos, some applications) to the map.

• 📁 Move it right away – the system will automatically move supported files.
• ⏳ Delay - transfer can be done later manually through Settings → Annexes → [Choice of application] → Warehouse → Change.

Important: After the merger SD-The card cannot be retrieved without first unmounting through the settings, otherwise the data may get damaged and the phone will stop loading.

Step 3: Checking the Results

To ensure that the memory is successfully combined:

1. Open the Settings → Storage.
2. Look at the memory usage chart – now it should display the total amount (internal memory) + SD-map).
3. Try installing a new app and select SD-card.

💡

If applications start to slow down after combining, try transferring them back to internal memory or use them. SD-class A2 (application-optimized).

What if the option “Format as internal” is not available?

If your Xiaomi Redmi settings don’t have the ability to combine memory, it could be due to:

• 🔒 Blocking the function in firmware – especially relevant for Chinese versions MIUI.
• 📱 Hardware limitations – some budget models (e.g. Redmi) 9A) Not supported by Adoptable Storage.
• 🗃️ Inappropriate. SD-card – requires a card with a volume of 16 GB and a class not lower than Class 10.

In such cases, there are several alternative solutions:

Method 1: Use of the SD-maps as portable storage

If the unification is not possible, configure the card as a portable storage:

1. Go to Settings. → Warehouse → SD-map → Three points. → Storage settings → Portable storage.
2. Format the card (if required).
3. Manually transfer files (photos, videos, music) to the map through any file manager.

The downside of this method is that applications will still only be installed in internal memory.

Method 2: Transfer applications to SD-hand-write

Some applications (not all!) can be moved to the SD-cardboard without combining memory:

1. Open Settings → Applications → Application Management.
2. Select the application → Warehouse → Change. → SD-map.
3. Confirm the transfer.

Limitations:

• ❌ Not all apps support portability (especially system and games).
• ⚠️ After the transfer, the widgets of the application may stop working.
• 🔄 When you extract the map, the transferred applications will become unavailable.

Method 3: Installation of custom firmware

For advanced users, there is a radical method - installing an informal firmware (for example, LineageOS or Pixel Experience), where the Adoptable Storage function is unlocked.

• 🔓 Requires unlocking the bootloader (risk of loss of warranty).
• 🛠️ It can cause unstable operation of the phone.
• 🔄 It will require a complete data reset.

Risks and pitfalls: what to fear?

Memory integration is not a harmless procedure, and here are the real challenges Xiaomi Redmi users face after activating Adoptable Storage:

⚠️ Attention: If SD-The card will fail (for example, due to physical damage or failure of the file system), you will lose not only the data on it, but also access to some applications installed in the "combined" storage.

Problem 1: Slowing down the phone

SD-cards (even class) A2) They are slower than the built-in memory. eMMC/UFS. This leads to:

• 🐢 Slowing down the launch of applications transferred to the map.
• 🎮 Laham in games (textures load longer).
• 📸 Delays in saving photos/video to the map.

Solution: leave on the internal memory of frequently used applications (messengers, social networks) and transfer to the internal memory SD-Only "heavy" games or rarely used programs.

Problem 2: Inability to extract the map

After the merger SD-The card becomes part of the system:

• 🔌 Remove it without "safe extraction" (Settings) → Warehouse → SD-map → Remove, the phone may stop loading.
• 🔄 Insert it into another phone or PC, the system does not recognize the file system (it is encrypted).

Solution: Always use the Safe Retrieval feature before physically deleting the card.

Problem 3: Failures after the update MIUI

With major updates MIUI (For example, from 12 to 13), the combined memory can "fall apart":

• 🔄 The phone will stop seeing. SD-map.
• 📱 Apps installed on the map will disappear.
• 🔧 Re-formatting with loss of data will be required.

Solution: Before Updating MIUI Back up all your data and be ready to reconfigure the storage.

💡

Memory integration is not a panacea. If you're critically interested in your phone's speed, you might want to consider buying a model with a lot of internal memory (64/128 GB or use cloud storage (Google Drive, Mi Cloud).

Alternative ways to expand memory on Xiaomi Redmi

If memory unification is not possible or you are not willing to put up with its shortcomings, consider these options:

1.Use of OTG-storage

With help. USB OTG-Adapter to Xiaomi Redmi can be connected:

• 🖥️ Flash drive (up to 256 GB).
• 💾 Outside SSD/HDD (Additional power will be required for the discs 2.5").

Pros:

• ✅ No volume limit.
• ✅ You can quickly turn off the drive.

Cons:

• ❌ Takes up the connector. USB-C (You can’t charge your phone at the same time).
• ❌ Not all applications can work with OTG-storage.

2. Cloud storage

Services like Google Photos, Mi Cloud or Yandex Drive allow you to:

• 📸 Automatically upload photos/videos to the cloud.
• 📄 Keep backup copies of contacts and notes.
• 🎵 Stream music without downloading to the device.

1. Go to Settings → Xiaomi Account → Mi Cloud.
2. Select the Gallery → Autoload.
3. Activate the option and adjust the download quality.

3. Optimization of internal memory

Before buying a new one SD-Try to free up the cards:

• 🧹 Clear the app cache in Settings → Warehouse → Cleanup.
• 🗑️ Remove duplicate photos with Google Photos or Gallery Go.
• 🎮 Transfer the game cache (for example, PUBG Mobile or Call of Duty on SD-hand-card through game settings.
