Why USB is the most reliable way
Transfer files from computer to smartphone Xiaomi through USB-Cable is still the fastest and most stable method, despite the proliferation of cloud services and wireless technologies. Unlike Wi-Fi Direct or Bluetooth, cable connection does not depend on network quality, does not consume battery power for data transfer and guarantees a maximum speed (up to 480 Mbps for the mobile phone). USB 2.0 and 5-10 Gbps for USB 3.0).
However, many users face typical problems: the computer canβt see the phone, files are not copied, or the smartphone offers only charging instead of data transfer. USB-mode, outdated drivers or firmware features MIUI. In this article, we will take a look at all the nuances β from choosing a cable to solving rare errors β so that the transfer of files takes minutes, not hours.
Particular attention will be paid to Xiaomi models of recent years (Redmi Note 12/13 series, POCO F5/X5, Xiaomi 13/14), where the manufacturer has introduced additional restrictions on access to the file system via USB.
What files can be transferred via USB
USB-Connection allows you to transfer almost any type of files, but with some restrictions. MIUI Android:
- π Documents:.pdf,.docx,.xlsx,.txt - no size restrictions (except free space on your smartphone).
- π΅ Media files: photos (.jpg,.png,.raw), video (.mp4,.mkv), music (.mp3,.flac). MIUI automatically sorts them into folders DCIM, Music, Movies.
- π± APK-Files: Application installers (.apk,.xapk) Require permission to install from unknown sources (Settings) β Annexes β Special access β Installation of unknown applications).
- π§ System files: backups (.zip,.tar), firmware (.tgz) portable, but installation may require unlocking the bootloader.
Important: some folders on Xiaomi are protected from writing via USB. For example, you can not directly modify files to /system or /data without root rights, and MIUI can block the transfer of files with suspicious extensions (for example,.exe,.bat) for security reasons.
β οΈ Note: When transferring large files (>4 GB) use the exFAT file system or NTFS flash-drive/memory card. FAT32 Does not support files more than 4GB.
Preparation for transmission: cable selection and port check
Quality. USB-Cheap cables often have thin wires or damaged contacts, resulting in loss of connection or slow transmission:
- π Use original cable from the kit or certified USB-C β USB-A (PC-based) / USB-C β USB-C (modern-day laptop).
- β‘ For maximum speed, choose cables with support USB 3.0/3.1 (usually marked with blue of the connector).
- π Check the port. USB On a computer, the rear ports of the system unit are usually faster than the front panels. On laptops, give priority to ports with a symbol SS (SuperSpeed).
Also make sure the port is clean β dust or debris can prevent reliable contact. Use a dry toothbrush or compressed air (canister) to clean. Avoid metal objects so as not to damage the contacts.
| Type of cable | Max, speed. | Compatibility with Xiaomi | Notes |
|---|---|---|---|
| USB 2.0 | 480 Mbps (~60 MB/s) | All models. | The most common, but slow for large files. |
| USB 3.0/3.1 Gen1 | 5 Gbps (~600 MB/s) | USB-C port models (starting with Redmi Note 7) | Requires a cable with additional contacts (usually a blue connector). |
| USB 3.1 Gen2 | 10 Gbps (~1.2 GB/s) | Xiaomi 11/12/13/14, POCO F4/F5 | The real speed is limited by the smartphone controller (~400-800 MB/s). |
Step-by-step: how to connect Xiaomi to a PC
The file transfer process consists of three steps: physical connection, USB mode selection, and actual copying. Let's go through each step in detail.
- Connect the cable to your smartphone and computer. On the Xiaomi screen, a notification will appear "Charge via USB".
- Unlock the smartphone screen (if it is locked, the PC will not see the device).
- Swipe down the notification bar and tap on the message βCharge via USBβ (or βUSB for file transferβ).
- In the window that opens, select the mode: π File transfer (MTP) β Copying media and documents. π₯οΈ Image transmission (PTP) β if MTP not working (less often). π Charging only β disables data transfer.

βοΈ Checklist before transferring files
Optimization of transmission speed
Even with USB 3.0, the actual copy speed may be lower than expected.
- π Disable sync with the cloud (such as Google Photos or Mi Cloud) for the time of transfer β it consumes the CPU resources.
- π Archive files before copying: one.zip or.rar archive will be transferred faster than thousands of small files.
- π Use the back ports USB PCs β they are connected directly to the motherboard, unlike front panels that often go through the hub.
- π οΈ Disable the antivirus for transfer time β some programs (for example, Avast or Kaspersky) scan files in real time, slowing down the process.
Critical detail: Xiaomi smartphones with MIUI 13+ firmware include the default USB Optimization feature, which limits the transmission speed to save power. To turn it off, go to Settings β Battery β Optimize USB and deactivate the slider.
| Factor. | Impact on speed | How to fix it |
|---|---|---|
| USB 2.0 cable | Limitation ~60 MB/s | Replace it with USB 3.0 with a blue connector. |
| FAT32 file system on a memory card | 4GB File Limitation | Format the map in exFAT. |
| Background processes on Xiaomi | Slowdown of 20-40% | Close all applications through the recent ones. |
Solving common problems
If the computer can't see Xiaomi or the files aren't copied, the reasons can be both software and hardware.
1. The computer does not recognize the device
- π₯οΈ Windows: Update drivers through Device Manager (Look for Unidentified Device" β "Update the driver" β "Automatic search").
- π§ Linux: Install mtp-tools and libmtp via the terminal: sudo apt install mtp-tools libmtp-common
- π MacOS: Install Android File Transfer from Googleβs official website.
2.Xiaomi offers charging only
If the USB menu does not have the option "File Transfer":
- π§ Check the developer settings: turn on Debugging by USB (Settings β The phone. β Version. MIUI β 7 times to tap β return to β For developers).
- π± Restart your phone in Safe Mode (hold the power button) β "Safe Mode β This will disable third-party apps that may block MTP.
β οΈ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) after upgrading to MIUI 14 may be missing option MTP. In this case, the resetting of settings will help. USB: Go to Settings. β Connections and sharing β Resetting settings USB.

Alternative methods of file transfer
If USB-Connection is not available for some reason, consider alternatives:
- π Mi Drop (built-in) MIUI): Wireless transmission via Wi-Fi Direct. ~10-15 MB/s, but you don't need to use the Internet. Open Mi Drop on your smartphone. Select "Send files" β scan QR-computer code (needs browser).
- βοΈ Cloud services: Google Drive, Mi Cloud, Yandex Disk. Suitable for small files (up to 2 GB), but depends on the speed of the Internet.
- π‘ FTP-server: Applications like FX File Explorer or Solid Explorer is now available FTP-server on a smartphone and connect to it through Windows Explorer (enter ftp://[IP-address] in the address line).
Comparison of methods:
| Method | Speed. | Limitations | When to use |
|---|---|---|---|
| USB-cable | 60-800 MB/s | We need a cable, a USB port. | Large files (>1 GB) and no internet |
| Mi Drop (Wi-Fi Direct) | 10-15 MB/s | It only works between Xiaomi devices | Transfer between phone and laptop Xiaomi |
| FTP over a local area network | 5-50 MB/s | Requires tuning, one IP-range | Regular transmission between PC and phone |
