How to expand memory on Xiaomi: a complete guide with instructions for all models

Why Xiaomi is running out of memory and what to do about it

Owners of Xiaomi smartphones sooner or later face the problem of lack of internal memory. Even if initially 64 or 128 GB seemed sufficient volume, over time, high-resolution photos, video 4K, App cache and system updates eat up precious gigabytes, especially for the budget models of the Redmi series and the Redmi series. POCO, where the manufacturer often saves on the amount of storage.

Fortunately, there are several ways to expand memory on Xiaomi, from physically adding a memory card to optimizing existing storage. In this article, we will discuss all the current methods, their pros and cons, as well as give recommendations for specific models. It is important to understand that not all methods are universal: for example, flagships Xiaomi 13 and Mix Fold 3 do not support microSD cards, but offer advanced cloud options.

Before you get to the instructions, check what exactly takes up space on your device. Go to Settings → About Phone → Memory. Here you will see the categorization of applications, media, cache and system files. If the bulk is photos, videos or music, physical expansion methods will suit you. If the problem is in system debris, cleaning and optimization will help.

Method 1: Using a microSD memory card

The most obvious and common method is to install a microSD card. Most Xiaomi models (except for the flagships of recent years) support expansion to 1 TB using microSDXC or microSDHC cards.

• 🔹 Compatibility: Check in the specifications of your model, whether the microSD is supported. for example, Xiaomi 12 Pro and newer are deprived of a card slot.
• 🔹 Speed: To record video 4K or running applications from a card need a class UHS-I U3 or A2.
• 🔹 Formatting: Maps larger than 32 GB require an exFAT file system (instead of a 32 GB file system). FAT32).

To install a memory card:

1. Turn off your smartphone and find a microSD slot (usually combined with a tray for the microSD slot). SIM-map).
2. Insert the card before clicking. For hybrid slots (Redmi Note 10, POCO X3), you will have to choose either a second SIM or a microSD.
3. Turn on the device. The system will suggest formatting the card as portable storage (for files) or internal memory (for applications).

⚠️ Warning: Formatting the card as an internal memory (Adoptable Storage) binds it to the device, after extraction, the data will be unavailable on other gadgets, this mode can also slow down some applications.

Method 2: Transfer data to the Mi Cloud

If your Xiaomi model does not support memory cards (such as Xiaomi 13 Ultra or Mix 4), the alternative is Mi Cloud storage, which is integrated into MIUI firmware and offers:

• 📁 Automatic synchronization of photos, contacts and notes.
• 🔄 The ability to free up space on the device, leaving only thumbnails in memory.
• 🔒 5 GB free (extra 50–200 GB – from 99 GB) ₽/month).

To set up the cloud:

1. Go to Settings → Xiaomi Account → Mi Cloud.
2. Enable synchronization for the desired categories (e.g. Gallery or Records).
3. Activate the option to Free up space in the Gallery section - this will replace the original photos on the device with optimized versions.

Mi Cloud is convenient for backup, but has limitations: free rate of only 5 GB, and to download high-quality video will require a paid subscription.

💡

Before downloading files to Mi Cloud, connect to a Wi-Fi network – this will save mobile traffic and speed up the process.

Method 3: Optimizing the internal memory

Often memory problems are solved without buying cards or subscriptions. MIUI has built-in tools for cleaning up garbage and managing files.

1. Cache Clearing: Go to Settings → Apps → App Management, select frequently used programs (like Telegram or Instagram) and click Clear Cache.
2. Removal of duplicates: The Gallery has the function of Search for duplicates (in the menu) ⋮ → Tools. She finds the same photos and videos taking place.
3. Clean up downloads: The Download folder is often clogged with unnecessary files. Check it through Files (File Manager app).

For deep cleaning, use the built-in Security app:

1. Open Security. → Cleanup.
2. Click Deep Clean and select categories to analyze (such as Residual Files or Large Files).
3. Delete unnecessary data by following the system’s prompts.

⚠️ Note: Smart cleaning function in MIUI can delete files from the folder DCIM (Photos and videos) if they have not opened for more than 30 days, check settings before using them or transfer important media files to another place.

Method 4: Connecting an external drive over OTG

If your Xiaomi supports OTG (On-The-Go), you can connect an external hard drive or flash drive via a USB-C → USB-A adapter.

• 📸 Transferring large media files (such as drone or camera video).
• 🎮 Game Storage (some titles from Google Play let you install data on an external drive).
• 📂 Backup of important documents.

Instructions for connection:

1. Buy it. OTG-Adapter (for modern models, you need to use it) USB-C, For the old ones, Micro-USB).
2. Connect a flash drive or HDD to the adapter, then insert into the smartphone.
3. Notifications will appear USB-The drive is connected. Click on it to open the files.
4. Use File Manager to move data between your internal memory and your external drive.

Note that not all flash drives and HDDs are compatible with Xiaomi. For stable operation, choose drives with an exFAT or NTFS file system (the latter requires root rights). Also note that some models (for example, Redmi 9A) may not provide enough power for hard drives, in which case you will need an externally powered hub.

Method 5: Use of Network Storage (NAS or PC)

For users who work with large amounts of data (such as video editing or photography), the best solution is to use NAS network storage or connect to a PC over a local network.

• 🌐 Access files from any device on the home network.
• 🔄 Automatically sync folders (for example, through Syncthing or Resilio Sync).
• 🛡️ Avoiding dependence on limited cloud services.

Configure access to the NAS or PC:

1. Install a PC access program (such as Samba for Windows or NFS for Linux).
2. On a Xiaomi smartphone, install a file manager with network support, such as Solid Explorer or FX File Explorer.
3. In the application menu, select Network → Local area network and add a new connection by specifying IP-PC address, login and password.
4. Now you can move files between your smartphone and PC without wires.

To automate synchronization, we recommend Foldersync (paid but with trial period) which allows you to set a schedule to back up photos, documents or music on the NAS, for example, you can set up a daily sending of new photos from the DCIM folder to the network disk.

⚠️ Note: When connecting to NAS over Wi-Fi, the data rate will be limited by the bandwidth of your router. 4K) Use a 5 GHz network or cable connection via OTG-adapter with Ethernet port.

Memory Expansion Methods Comparison: What to Choose?

Each of these methods has its pros and cons, and to make it easier to choose, we have compiled a comparison table with key parameters in mind:

A critical nuance for Xiaomi owners with a Snapdragon processor: some models (such as the POCO F3 or Redmi K40) do not support microSD formatting as internal memory due to the limitations of the chipset.

💡

For most users, the best solution is a combination of microSD (for media files) and regular memory cleaning through built-in MIUI tools.

Frequent Mistakes and How to Avoid Them

When expanding memory on Xiaomi, users often face typical problems, and here are the most common ones and ways to solve them:

• 🚫 Memory card is not detected: Check if your model supports microSD (see table above). If there is a slot but the card is not readable, try formatting it on your PC in exFAT and pasting it back in. If it doesn't work, there is a problem in the slot (repair required).
• 🚫 Applications are not installed on the map: B MIUI The solution is to use the card as internal memory (with formatting), but this will reduce performance.
• 🚫 Mi Cloud is not synced: Make sure your device has Auto Sync enabled in your account settings. Also check if you are blocking cloud access in Settings → Annexes → Permit management.
• 🚫 OTG-Drive doesn’t connect: Try another adapter or check if your model supports OTG (via USB OTG Hard drives may require additional power.

If you run out of memory after all the manipulations, consider buying a smartphone with a large storage capacity. For example, Xiaomi 13T Pro offers versions with 512 GB and 1 TB of internal memory, which solves the problem radically.
