How to combine your phone memory and SD-Xiaomi Redmi Note 5 maps: full guide

Why to combine memory on Redmi Note 5

Owners of Xiaomi Redmi Note 5 often face a shortage of internal memory, especially if the model is purchased with a minimum volume (16 or 32 GB). Even after cleaning the cache and removing unnecessary files, the system can issue notifications about overflowing storage. The solution is to combine internal memory with a microSD card, a feature available on Xiaomi smartphones thanks to the branded MIUI shell.

The combination allows the use of SD-The card is part of the main storage: applications, photos and documents are automatically saved to the extended volume, but the procedure has a nuance: not all memory cards are suitable, and once combined, they can not be removed without losing data. In this article, we will analyze the step-by-step instructions for the Redmi Note 5, compare the pros and cons of the method, and also consider alternative ways to free up space.

Important: the procedure is different from the standard formatting of a card as a portable drive, and it's about creating an extended volume (Adoptable Storage) that becomes an integral part of the system, and it requires resetting the card and binding it to a particular device.

Requirements for a memory card for combination

Not every microSD is suitable for memory expansion on the Redmi Note 5. Xiaomi has strict requirements for drives to avoid problems with performance and stability of the system.

  • πŸ”Ή Speed class: minimum class 10 (UHS-I U1/U3). The cards with the class below lead to lags when writing data.
  • πŸ”Ή Volume: from 16 GB to 256 GB. Optimal - 64 or 128 GB (large volumes may not be supported by older versions). MIUI).
  • πŸ”Ή Format: exFAT only or FAT32 (The system itself formats the map into ext4 or f2fs unionize).
  • πŸ”Ή Brand: SanDisk, Samsung cards are recommended EVO, Kingston Canvas – Cheap no-name drives often fail.

Before buying, check the compatibility of the map model with the Redmi Note 5 on forums (such as 4PDA or XDA Developers).Some users report problems with Transcend and Silicon Power cards on MIUI 9-10.

⚠️ Warning: Once combined, the card cannot be retrieved without completely resetting the phone, and all data on it will be erased during the setup process.

Preparing the phone before combining memory

Before starting the procedure, follow the mandatory steps to avoid data loss or failures:

  1. Back up all important files (photos, contacts, messages) through Settings β†’ Additional β†’ Backup or third-party services (Google Drive, Mi Cloud).
  2. Charge the phone at least 50%. The process of combining can take 10 to 30 minutes, and interruption due to battery discharge will lead to errors.
  3. Remove unnecessary apps and clear the cache through Settings β†’ Apps β†’ Cleanup.
  4. Check out MIUI version: Memory integration is available on MIUI 8 and later. You can find out the version in Settings β†’ About Phone β†’ MIUI version.

If you already have files on your memory card, copy them to your computer or cloud, and when you combine them, all the data will be deleted and the card will be formatted into the system partition.

Step-by-step: how to combine memory on Redmi Note 5

The procedure is done through standard MIUI settings, and it's important to follow the instructions without omissions to avoid errors.

  1. Insert the memory card into the Redmi Note 5 slot (the hybrid slot supports either 2 SIM + microSD or 1 SIM + microSD).
  2. Open the settings and go to Settings β†’ Memory β†’ Memory Map.
  3. Click on the option β€œFormat as internal memory” (or β€œUse as internal memory” in newer versions of MIUI).
  4. Confirm the action and wait for the formatting to be completed. The phone may reboot.
  5. Select the option of data transfer: πŸ“± Move now – data from internal memory will automatically move to the card (it will take 5-15 minutes). πŸ“± Move it later – the data will remain in place, but new files will be saved on the combined volume.

Reboot the phone.

Once combined, a single volume with a total volume (e.g., β€œ32 GB + 64 GB = 96 GB”) will appear in the Memory section. However, some of the memory will be occupied by system files, so ~85-90% of the total volume will be available.

What if the option β€œFormat as internal memory” is not available?
If there is no unification point in the settings, it means: 1. Your memory card is incompatible (check the speed class). 2. An outdated version of MIUI is installed (update via Settings β†’ About Phone β†’ System Update). 3. The phone does not support the function (rarely found on custom firmware).

Problems and errors in memory integration

Even if you follow the instructions correctly, Redmi Note 5 users may encounter errors.

If the phone starts to overheat or run out quickly after the combination, return the settings to the original state: go to Settings β†’ Memory β†’ Memory Map and select β€œFormat as portable.” This operation will delete all the data on the map and return it to its original state.

⚠️ Note: Some banking applications (e.g. Sberbank Online) may not work on a combined volume due to security requirements, in which case, transfer them back to internal memory.

Alternative ways to free up memory on the Redmi Note 5

If memory integration is not available or suitable for some reason, consider alternative methods:

  • πŸ”„ Cache Clearing: Regularly delete temporary files through Settings β†’ Memory. β†’ Cleanup.
  • ☁️ Cloud Storage: Automatically upload photos to Google Photos or Mi Cloud and delete local copies.
  • πŸ“ Manual File Transfer: Use a file manager (such as Mi File Manager) to move media files to the map.
  • πŸ”§ Disabling Pre-installed Applications: Through Settings β†’ Applications can be disabled from unnecessary system programs (for example, Mi Music or Mi Video).

For advanced users, manual folder linking through FolderMount (root rights required) is a good way to move individual directories (such as a folder with a photo from DCIM) to a map without completely combining.

To speed up the phone after memory is combined, turn off the interface animation. To do this, activate Developer Mode (7 times click on the MIUI version in the phone settings) and in Settings β†’ Additional β†’ For developers, set Windows Animation, Transition Animation and Animator Duration at 0.5x.

How to Get Everything Back: Undoing Memory

If after the merger you have encountered problems (hangs, application errors) or decided to sell the phone, you can return the memory card to its original state.

  1. Go to Settings β†’ Memory β†’ Memory Map.
  2. Click on the three dots in the top right corner and select β€œStorage settings”.
  3. Tap β€œFormat as portable” (or β€œDisable”).

  5. After formatting, remove the card and paste it again - it will be defined as a conventional removable drive.

If the shutdown option is not available, try resetting your phone to factory settings via Settings β†’ Additional β†’ Restore and Reset. This will delete all data from internal memory, so pre-backup.

After cancellation of the card can be used in other devices, but all data on it will be permanently deleted.

FAQ: Frequent questions about memory pooling on Redmi Note 5

Can I combine memory on Redmi Note 5 without losing data?
No, the process involves formatting the memory card, so all the data on it will be erased, but you can save files from the phone's internal memory by selecting "Move later" instead of "Move now."
Why did the phone stop after the memory was combined?
You’re probably using a memory card with a low write rate (class below UHS-I U1), replace it with a faster model (such as the SanDisk Ultra A1), and brakes can occur due to the simultaneous writing of data to the card and internal memory.
Can I remove the memory card after the merger?
Technically, you can extract it, but it will cause errors in the application and system, and the card becomes part of the internal storage, and deleting it is equivalent to removing the hard drive from the computer while you're working. For safe extraction, first uninstall the connection through settings.
Does the Redmi Note 5 support 512GB memory cards?
Officially, Redmi Note 5 supports cards up to 256 GB. 512 GB cards can work, but stability is not guaranteed (read/write errors are possible).
How to transfer applications to a memory card after combining?
Once combined, new applications will default to an extended volume. To transfer already installed programs: Open Settings β†’ Applications. Select the desired application. Click Storage β†’ Change β†’ Memory Map. Not all applications support portability (for example, system or high security requirements).
