How to expand memory on Xiaomi phone: a complete guide with instructions and life hacks

Owners of Xiaomi smartphones sooner or later face the problem of lack of internal memory. Even flagship models with 256 GB after a year or two of active use begin to “choke” from high-resolution photos, heavy games and cache of applications. and budget Redmi and POCO with 32-64 GB of memory turn into a “race for megabytes” in a few months.

In this article, we’ll look at all the ways Xiaomi can expand memory, from classic microSD cards to obscure tricks with adaptable storage and cloud services, which is right for your model, how to avoid formatting errors, and what to do if your phone doesn’t see the memory card, and also unique data on the compatibility of memory cards with popular Xiaomi models 2022-2026.

1. MicroSD Memory Cards: How to Select and Install

The most obvious way to expand memory is to use a microSD card. But it's not that simple: Xiaomi imposes limits on maximum volume, speed and even drive brands. For example, the Redmi Note 12 Pro officially supports cards up to 1 TB, but in practice, some SanDisk Ultra models are experiencing problems.

Before you buy a card, check:

• 🔍 Maximum volume supported (listed in the model specifications on the Mi.com website). For most modern smartphones, it is 512 GB-1 TB.
• ⚡ Speed class: for recording video 4K need UHS-I U3 or V30, Applications: Minimum Class 10.
• 🏷️ Manufacturer: it is better to choose SanDisk, Samsung EVO Kingston Canvas – They are less likely to cause errors.

Installation of the card takes less than a minute:

1. Turn off your phone (required!).
2. Insert the card into the slot (on most models it is combined with a tray for SIM).
3. Turn on the device and wait for the identification of the drive.
4. Go to Settings → Memory → SD card and choose the format: portable (for files) or internal (for applications).

⚠️ Note: If you choose the internal format, the card will be encrypted and not readable on other devices, and it will not be retrieved without data loss.

Adaptable Storage: How to Make a MicroSD into a Second Internal Memory

The Adoptable Storage feature allows you to “tie” a microSD card to your phone so that the system perceives it as part of internal memory, which is especially useful for installing applications that normally cannot be transferred to a removable drive.

How to turn on:

1. Insert the card and go to Settings → Memory → SD card.
2. Press "Three dots» (⋮) → Storage settings → Formatting as an internal storage device.
3. Confirm the action (all data on the map will be erased!).
4. After formatting, select Transfer Data to move some of the applications to the map.

Important nuances:

• 🔄 After activation of the adaptable storage card can not be removed without resetting the phone to the factory settings.
• ⚡ The speed of applications from the card will be lower than from internal memory (especially on cheap microSD).
• 📱 Not all Xiaomi models support this feature. POCO X3 It works on the Redmi 10, but it doesn’t.

3. Internal Memory Optimization: What Can Be Safely Deleted

Before you spend money on a memory card, try to free up space on the internal drive. Xiaomi accumulates a lot of junk files that can be deleted without risk to the system.

Where to look for the extra:

• 🗑️ App cache: Settings → Annexes → Select an application → Warehouse → Clear cache. Especially voracious Facebook, Instagram and TikTok.
• 📸 Duplicate photos: use the built-in Gallery app → Albums. → Duplicate.
• 🎮 Game data: C Settings → Memory. → Memory analysis find games with volume >1GB and clear their cache.
• 📥 Downloads: Download folder often contains unnecessary APK, archives.

For deep cleaning, use the built-in Security app (shield icon):

1. Open Security. → Cleanup.
2. Click Deep Clean and select unnecessary files.
3. In the Acceleration section, you can close the background processes that consume memory.

⚠️ Note: Do not manually delete folders with Android names, MIUI Or system, which can cause a system crash, and don't touch files with the.odex or.apk extension in the root folders.

4. Transfer applications to a memory card (even if the function is disabled)

Many Xiaomi users are faced with the fact that the option to migrate applications to the microSD is not in the settings. This is due to the MIUI policy, but there are workarounds.

Method 1: Through the Developer's Settings

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the option Forced to allow porting to SD and turn it on.
4. Now in the application settings will appear button Move to SD-map.

Method 2: With ADB (for Advanced)

If the previous method didn’t work, use the ADB command:

adb shell pm set-install-location 2

This command will cause the system to install applications on the memory card by default. To return everything back, use:

adb shell pm set-install-location 0

💡

Before using ADB, make sure that there is enough space on the memory card (at least 10-15% of free space), otherwise the applications will not work.

5. Cloud Storage: How to Free Memory Without a MicroSD Card

If your Xiaomi model doesn’t support microSD (like Xiaomi 13 Ultra or Mix Fold 3), the alternative is cloud services. Xiaomi offers its own Mi Cloud, but its free tariff is limited to 5 GB.

Comparison of cloud services for Xiaomi:

How to set up autoload photos in Google Photos:

1. Install the Google Photos app from the Play Market.
2. Open the settings → Backup and synchronization.
3. Enable the option and select quality (High - unlimited storage, Original - counted in the quota of 15 GB).
4. In the Storage Management section, you can delete local copies of the photo after uploading to the cloud.

6. Alternative methods: OTG-drives and network disks

If neither the memory card nor the cloud fit, consider the less obvious options:

1. USB-storage OTG

With help. OTG-adapter (stands) ~200–500 ₽) You can plug in a flash drive or an external hard drive. Xiaomi supports the file system. FAT32, exFAT and NTFS (starting MIUI 12).

• ✅ Pros: you can use drives up to 2 TB, high read / write speed.
• ❌ Cons: Inconvenient to carry with you, requires constant connection.

2. Network Storage (NAS)

If you have a router at home USB-port (for example, Xiaomi Router) AX6000), You can plug a hard drive into it and set up access over the local network:

1. Connect the disk to the router.
2. In the router control panel, turn on Network Storage (Samba).
3. On your phone, install the File Manager+ or FX File Explorer app.
4. Add the network drive to smb://192.168.x.x (IP of your router).

3. PC as a remote storage

With the Mi Drop app (built into MIUI), you can transfer files between your phone and your computer over a local network without Internet, and transfer speeds reach 10 to 50 MB/s.

7. Frequent errors and their solutions

When working with memory on Xiaomi, users often face typical problems.

1.The phone doesn't see the microSD card

• 🔌 Reboot the phone.
• 🔄 Remove the card and re-insert (check if the slot is not contaminated).
• 🛠️ Format the map on PC in FAT32 exFAT.
• 📱 If the card is new, check it on another device – it may be defective.

2. Applications are not portable to the map

• 📌 Make sure the card is formatted as internal memory.
• 🔧 Check if the application supports portability (some games and system utilities cannot be moved).
• 🛠️ Use it. ADB-section 4.

3. Slow operation of applications from the map

• ⚡ Buy a card with a speed class UHS-I U3 or V90.
• 🗑️ Do not fill the card more than 80% – it reduces the speed.
• 🔄 Transfer only light applications (messengers, readers) to the map, and leave the games in your internal memory.

💡

If the memory card suddenly stops being defined, don't rush to format it! Try erasing the contacts with a pin (without pressing) - often a problem in oxidation.
