How to transfer data to Xiaomi Redmi 9 with NFC

Replacing a smartphone is always stressful, not so much with the device itself, but with the need to transfer a huge amount of personal information. The situation when you need to transfer data from an android to the android Xiaomi Redmi 9 with NFC is solved much easier than it seems at first glance, thanks to modern wireless technologies. Owners of budget but powerful models such as the Redmi 9 often face the question of effective migration, and the built-in module of short-range contactless communication here is a great catalyst for the process.

Using NFC (Near Field Communication) technology not only allows you to pay for purchases, but also significantly speed up the initial setup of a new gadget. Instead of looking for cables or installing third-party programs, you can use the built-in capabilities of the MIUI system to create a direct channel between devices, this is especially true when you need to quickly activate a new phone and start using it without spending hours manually adjusting each setting.

In this article, we will discuss in detail all the nuances of the process, from the preparation of equipment to the solution of possible synchronization errors. NFC-We will also consider alternative methods in case the wireless protocol is unavailable or unstable in your situation.

Preparing devices for data migration

Before you start directly transferring information, you need to make sure that both smartphones are in good condition and ready to go. Charge the old phone and the new Xiaomi Redmi 9 to at least 50%, as the process of cloning the system can be energy-intensive and long. Lack of battery power can lead to a sudden shutdown of the screen or the device itself, which will interrupt the transmission of data packets.

Make sure both devices have a wireless module on. On an old smartphone, go to settings and activate a feature that allows you to read tags and exchange data when you touch. On the new device, this feature must also be active so that it can receive the signal to start pairing. Without this step, automatic device detection will not be possible.

⚠️ Warning: Make sure the screens of both smartphones are unlocked and are active during the connection attempt. NFC-antennae.

While Redmi 9 has enough internal memory, when you transfer data from a device with a lot of media, the free space can run out unexpectedly. Delete unnecessary files or clear the basket before starting the procedure.

Use of the built-in Mi Mover application

The main tool for migration in the Xiaomi ecosystem is the pre-installed Mi Mover application. It is optimized for working with the MIUI shell and provides the most stable transfer not only of files, but also of system settings, desktop layouts and passwords from Wi-Fi. You can launch the application through the settings menu in the About Phone section or by finding it in the Tools folder.

When you first start up, the program will ask you to choose the role of the device: “I send” or “I receive.” On the new Redmi 9, you need to select the role of the recipient, after which the system will generate a new device. QR-code or suggest using NFC If you choose the option of a quick pairing, NFC, Just hold the tops of the phone cases to each other.

• 📲 The application automatically determines the type of data transmitted: contacts, messages, call logs and media files.
• 🔒 Transfers occur over a secure local channel, the data does not go to the cloud.
• ⚡ Copy speeds are much faster than using Bluetooth or cloud services.

Importantly, Mi Mover is capable of porting even installed apps, although some (especially banking) will require re-authorization, eliminating the need to manually download every software from the Play Market store, saving traffic and user time.

The role of NFC in the synchronization process

Many users mistakenly believe that all data is transmitted directly through the chip. NFC. Actually, NFC (Near Field Communication is used exclusively for "handshakes" - fast transfer of credentials of the Wi-Fi network or create a tunnel for further high-speed connection. NFC It has low bandwidth and is not designed to transmit gigabytes of photos.

When you bring devices together, the new Redmi 9 reads a configuration file from an old phone. This file contains data to create a Wi-Fi Direct hotspot. It's through this high-speed channel that the main flow of information will go. Using NFC here is critical to simplify the process: you don't have to manually enter Wi-Fi passwords or search for a device in a Bluetooth list.

If you don't have any vibrations when you're holding your phones, and you don't have the connection, try repositioning your devices. The NFC antennas in different Android models are in different places: someone on the top of the case, someone in the center, next to the camera. Experiment with position until you feel a slight vibration response.

⚠️ Warning: Remove thick protective cases or cases with metal inserts before attempting to connect. NFC, make it impossible to read the tag.

💡

If NFC doesn’t work, try turning the screen on both devices and unlocking them. Also make sure that the NFC settings select Read and Write or Android Beam (if available).

Step-by-step instructions for transfer via NFC

To perform a successful operation, follow an algorithm that guarantees that errors are minimized. First, open the Mi Mover app on both devices. On the old phone, click "I send" and on Redmi 9, "I accept." The system will ask for permissions to access contacts and storage - be sure to agree to all requests.

On the screen of the new phone will be a suggestion to use NFC Press the appropriate button. Now take the old smartphone and put it in the back to the top of the Redmi back. 9. Keep the devices tightly pressed against each other during 2-3 seconds until vibration occurs and an image appears on the screen QR-code-in.

Actions in connection failure:


1. Turn off and turn on NFC on both devices.




2. Make sure Wi-Fi is on (it is needed to transfer data after NFC- handshake).




3. Restart the Mi Mover app.




4. Repeat the procedure of attaching devices.

Once you pair successfully, the old device will have a list of data categories to transfer to, and you can select all of them at once, or you can only mark the necessary items, such as Gallery, Contacts, and Messages. Press Send and wait for the process to be completed. The progress bar will show the download status.

What data can and cannot be transferred

Understanding the limitations of migration will help avoid frustration. Mi Mover and NFC bundle allow you to throw a bulk of user information, but there are nuances related to Android security policy and app features. Below is a table detailing the types of data being ported.

For Telegram, it is easy to enter a phone number, since the history of correspondence is stored on the server. WhatsApp needs to select the appropriate option in Mi Mover when transferring data or make a backup to Google Drive before changing the device to restore chats.

System settings such as alarm clocks, wallpaper and desktop icon layout are also copied if you use the MIUI launcher on both devices.This allows the new Redmi 9 to look and behave exactly like your previous phone, creating a sense of familiar surroundings.

Solving Connection Problems and Errors

The migration process can be complicated by technicalities, and one of the most common problems is that it freezes at a certain percentage, usually due to unstable Wi-Fi connections between devices, in which case it is recommended to interrupt the process and repeat it by getting closer to each other or eliminating other active Wi-Fi networks in range.

Another problem is, "Device not found." This often happens if one of the phones has an energy-saving mode that restricts background services, turn off the power saving mode on both smartphones before starting the procedure, and check if the phones are "hard" firewalls or antiviruses that block local connection.

• 🔄 “Not enough space” error: Clear the app cache or delete part of the video before transferring.
• 📶 Weak Signal Error: Make sure there are no obstacles between the phones and they are no more distant 10-15 sm.
• 📱 Android Version Incompatibility: If the Old Phone Is Very Old (Android) 4.x Mi Mover may not work, you will need manual transfer.

⚠️ Warning: Do not attempt to interrupt the transmission process by turning off the screen or closing the application.This may damage the contact or message database files.

💡

Connection stability is more important than speed, and it's better to move data in two stages than risk losing some of the information because of a communication breakdown.

In some cases, especially when switching from custom Android builds or smartphones of other brands with a heavily modified shell, you may need to manually install the Mi Mover on an old phone. APK-You can file from the official Xiaomi website or through the built-in GetApps store.

Alternative methods and completion of the setup

If you can't use NFC and Mi Mover for some reason, you always have a reliable option with a Google Account. When you first turn on Redmi 9, type in your Gmail address and the system will suggest you restore a backup from the cloud. This method is good for contacts, calendar and app listing, but it doesn't always keep the folder structure and files inside the apps.

You can also use a USB-C to USB-C cable (if your old phone supports OTG) or an adapter. If you wire your devices, you run the same Mi Mover, but the transmission goes over the cable, which guarantees maximum speed and stability, eliminating any radio interference. This is ideal for carrying tens of gigabytes of photos and videos.

After the transfer is complete, take your time to reset your old phone. Use the new Redmi 9 for a couple of days to make sure all data is in place, notifications are coming and apps are working correctly.
