NFC (Near Field Communication) is no longer exotic β itβs now embedded in most Xiaomi smartphones, from budget Redmis to Mi or POCO flagships. However, many users still use it only for contactless payments, without even realizing that NFC can be used for lightning fast file transfer between devices. Unlike Bluetooth or Wi-Fi Direct, you donβt need to connect to networks, enter passwords or wait for synchronization β just attach the phones to each other.
In this article, weβll look at how NFC transfers work to Xiaomi, which models support this feature, and why it can sometimes be interrupted. Youβll learn not only the basic steps, but also the hidden MIUI settings that speed up file sharing by 2-3 times, and ways to bypass the data size restrictions. If youβve ever encountered a device not supported error or a transmission suddenly broke down, here youβll find solutions.
What Xiaomi models support file transfer via NFC
Not all Xiaomi smartphones have an NFC chip, and not all of them support file transfer.
- π± Flagship series: Xiaomi 12/13/14, Mi 11, POCO F4/F5 β support NFC Full functionality, including file sharing MIUI Quick Share.
- π° Mid-segment: Redmi Note 11/12 Pro+, POCO X5 Pro β NFC there, but manual activation may be required in settings.
- β οΈ Budget models: Redmi 10A, POCO M4 Pro (without prefix) 5G) β often deprived NFC or support only payments or payments.
- β Older devices: Xiaomi Mi A2, Redmi 9 and earlier β NFC It is either missing or works with errors when transferring files.
To find out exactly if your smartphone supports the feature, check the specifications on Xiaomiβs official website or do the following test:
- Open Settings β Connected Devices β NFC.
- Activate the NFC slider.
- If you see Android Beam or Quick Transfer, your device is compatible.
Preparing devices for file transfer
There are several steps that must be taken before sharing data, and neglecting them is the main reason why users encounter errors such as βDisconnectedβ or βDevice not detected.β
First, make sure that on both smartphones:
NFC enabled in settings
"Android Beam" or "Fast Transfer" mode activated
The screen is unlocked (on some models, the lock interrupts the connection)
Battery level above 15% (NFC energy-consuming when transferring large files)-->
Second, check for compatibility of MIUI versions. If one device has MIUI 14 installed and another has MIUI 12 installed, protocol conflicts may arise, in which case it is recommended to update the firmware to the latest version through Settings β About Phone β System Update.
β οΈ Note: Some models (e.g. Xiaomi Mi 11 Lite) feature file transfer via NFC It's turned off by default to save energy. To activate it, go to Settings. β Battery β Power saving mode and disable optimization for the application MIUI Quick Share.
Step-by-step: how to transfer a file over NFC
Now, let's get to the process. For example, take the transfer of photos from Xiaomi 13 Pro to POCO F4 GT. The algorithm is the same for most models, but the names of menu items may differ.
- Activate NFC on both devices via the notification panel or in Settings β Connected devices.
- Select a file to transfer. It could be a photo from a gallery, a document from a File Manager, or even a contact from a phone book.
- Put the back covers on each other, and you have to have a beep or you have a vibration, which means you've got a connection.
- Confirm the transfer on both screens. The receiving device will receive a notification prompting you to save the file.
Important: the distance between devices should not exceed 1-2 cm If you heard the connection sound, but the transfer has not started, try to slightly move the smartphones - sometimes the NFC chip is located not in the center.

If the transfer is interrupted at half, try to reduce the file size. NFC is optimal for data to 10 MB. For large files (video, archives), it is better to use Wi-Fi Direct.
NFC Limitations: What Can and Cannot Be Transmitted
Despite the convenience, the NFC has some very rigid limitations that few people know about, and here are the key points:
| File type | Max size. | Transmission speed | Notes |
|---|---|---|---|
| Photos (JPEG/PNG) | up to 15 MB | ~1-2 MB/s | Recommended format for NFC |
| Documents (PDF, DOCX) | up to 10MB | ~0.8 MB/s | Large PDFs can be transmitted with errors |
| Video (MP4) | 5MB | ~0.5 MB/s | Better to use Wi-Fi Direct |
| Contacts (VCF) | limitlessly | momentarily | Transmitted as a text file |
| APK-file | 8MB | ~1 MB/s | MIUI may be blocked due to security |
The main problem with NFC is its low speed compared to Wi-Fi Direct (up to 10 MB/s) or Bluetooth 5.0 (up to 2 MB/s), but the technology has an undeniable advantage: it does not require an Internet connection and does not consume mobile traffic, which is critical in the conditions of poor signal.
β οΈ Note: Do not attempt to transmit via NFC files larger than 20 MB, which will cause the process to freeze and the chip to overheat. MIUI automatically offer an alternative method (e.g., via Mi Share over Wi-Fi).
Common mistakes and their solutions
Even with the right setup, users often face problems, and here are the most common ones and ways to fix them:
- π "Device not detected: Check if it is switched on NFC Make sure the screen is unlocked (on some models, the lock turns off). NFC). Restart both devices β sometimes resetting the moduleβs temporary data helps.
- β "Transfer failed": Try to reduce file size (e.g. compress a photo). Turn off power saving mode in battery settings. Update MIUI Up to the latest version - in the old firmware there are bugs with NFC.
- π΅ "NFC Not switched on: Check if the antenna is damaged NFC (Frequently breaks after falls. Reset network settings: Settings β System system β Reset β Network reset. If nothing works, contact the service center (possibly faulty chip).
If you see a βNo Feature Supportedβ message on an NFC device, it could mean your model is not compatible with Android Beam (an outdated protocol), in which case use the alternative β the Xiaomi Quick Share app, which works via a combination of NFC and Wi-Fi Direct.
What if NFC is only for payments?
Alternative ways to transfer files to Xiaomi
If NFC is not suitable for some reason (for example, due to file size limitations), consider these options:
- πΆ Wi-Fi Direct: Up to 10MB/sec. Supports files of any size. Requires a single network connection or a direct connection.
- π΅ Bluetooth 5.0: Up to 2MB/s. Suitable for small files (up to 50MB) Less battery consumption than Wi-Fi.
- βοΈ Mi Cloud / Google Drive: Easy to back up. Requires Internet and account. You can share links to files.
- π OTG-cable: Instant transfer of large amounts of data, requires physical connection, supports external drives (flash drives, HDD).
For maximum convenience, Xiaomi has developed its own solution, MIUI Quick Share (formerly Mi Share), which automatically selects the optimal protocol (NFC for small files, Wi-Fi Direct for large ones) and works even between devices of different brands (if they have the Xiaomi Quick Share application from Google Play).

NFC is convenient for transferring small files (photos, contacts, documents), but for video or archives, it is better to use Wi-Fi Direct or Mi Quick Share.
Security for File Transfers via NFC
NFC is considered a safer method of transmission than Bluetooth or Wi-Fi, due to its short range (up to 10 cm).
- π Data interception: In theory, an attacker can intercept transmission if they're in close proximity. NFC only in the checked places.
- π¦ Malicious files: NFC Always check the data with antivirus (for example, Mi Security).
- π± Unauthorized access: On some models NFC It stays active even after you lock the screen. Turn it off in the settings if you're not using it.
For additional protection:
- Turn off automatic file downloads in Settings β Applications β MIUI Quick Share β Autoboot.
- Use a password or fingerprint to confirm the transfer.
- Update MIUI regularly β new versions will close NFC vulnerabilities.
β οΈ Note: Never pass through the NFC files with.apk,.exe or.bat extensions, obtained from unknown sources. MIUI blocks the installation of such files by default, but some modified firmware may miss them.
