Moving to a new smartphone always causes slight excitement, especially when years of correspondence, photos and important contacts have been accumulated on the old device. The model Redmi 9T has an impressive amount of memory and a powerful battery, which makes it an excellent candidate for the role of a main gadget, but the first step is always the migration of information. This process is not as complicated as it seems, but it requires attention to detail so as not to lose a single byte of valuable data.
There are several proven ways to carry out migration: from using the manufacturer’s proprietary utilities to cloud services and manual copying. The specific method you choose depends on the condition of your old device, the speed of your Internet connection, and your personal privacy preferences. In this article we will analyze in detail each of the available options, paying special attention to the specifics of the ecosystem. Xiaomi.
Before taking active steps, it is necessary to carry out basic preparation of both devices. Make sure both your old and new devices have at least 50% battery charge, or better yet, connect them to a power source. This is critically important, since the process of transferring large amounts of information, especially via Wi-Fi Direct, can be energy-intensive and time-consuming.
Preparing devices before migration
Successfully migrating data to Redmi 9T directly depends on the quality of preliminary preparation. The first step is to free up enough space on the receiving device, although this model usually comes with extra memory. However, checking the free space will help you avoid errors when writing files.
Update the operating system on both smartphones to the latest available version. Developers are constantly releasing security patches and improvements for data transfer protocols, which can significantly speed up the process. Go to Settings → About phone → MIUI version and check for updates.
⚠️ Attention: If custom firmware is installed on your old device or root access is obtained, standard transfer methods may not work correctly. In such cases, it is recommended to make a full backup to your computer before experimenting.
It is also worth deleting temporary files and application cache on your old phone. This will not only speed up the transfer, but also prevent the transfer of “garbage” that may have accumulated over years of use. Use the built-in cleaning utility or third-party applications to optimize the system before starting.
☑️ Ready for transfer
Using the Mi Mover application for fast transfer
The most effective and preferred way for equipment owners Xiaomi is to use the built-in tool Mi Mover. This application is specially designed for seamless data migration between Android devices and works on the principle of creating a secure communication channel.
On the new Redmi 9T application is already pre-installed in the “Tools” folder. On an old device, you need to download it from Google Play or the official website if a different shell is installed there. After launch, select the device role: “I am the sender” on the old one and “I am the recipient” on the new one.
Smartphones will find each other via a QR code or Wi-Fi hotspot. It is important to understand that at this moment a local network is being created, so the transfer speed will depend on the supported Wi-Fi standards on both devices. Mi Mover allows you to select specific categories of data for transfer.
- 📸 Photos and videos from the gallery
- 📞 Contacts and call log
- 📱 Installed applications and their data
- 🎵 Music and audio recordings
- ⚙️ System settings and alarms
When transferring via Mi Mover, do not minimize the application and do not lock the smartphone screen, as this may break the connection and interrupt the process.
After selecting categories, the copying process will begin. Waiting times vary from a few minutes to an hour depending on the amount of data. Upon completion, you will receive a detailed report on what was successfully transferred and what will require manual configuration.
Mi Mover is the fastest method, as it transfers data via a direct Wi-Fi channel without using the Internet, providing high speed and confidentiality.
Recovery from Google Account and cloud services
Alternative a method that is often used when initially setting up a new phone involves restoring data from the cloud Google. This method is convenient because it does not require the old device to be on hand when setting up a new one, if a backup copy has already been created.
When you turn it on for the first time Redmi 9T the system will prompt you to log in to your Google account. After authorization, you will be offered a list of available backups from other devices. Select the most recent backup date to restore the maximum amount of data.
Please note that this method primarily restores the list of applications, contacts, calendar and system settings. Media files (photos and videos) are restored only if synchronization with Google Photos.
| Data type | Recovered automatically | Requires additional. settings |
|---|---|---|
| Contact | Yes | No |
| Applications | Yes (list) | Login to accounts |
| Photo/Video | No (via Google Photos only) | Synchronization |
| Wi-Fi passwords | Yes | No |
| SMS messages | Depends on the Android version | Often required |
⚠️ Attention: Restoring from Google cloud requires a stable and fast Internet connection. When using mobile traffic, be careful, as the amount of data downloaded can amount to gigabytes.
This method is ideal for those who are used to living in the Google ecosystem and regularly make backups. However, for complete cloning of the phone, including arranging icons on the desktop, it is inferior to specialized utilities like Mi Mover.
Manual transfer via computer and USB cable
For users who prefer full control over the process or have problems with wireless connections, the classic method via a PC is suitable. This method is also relevant if you need to transfer very large files, for example, videos in 4K resolution.
You will need a USB Type-C cable. First connect your old phone to the computer and select the file transfer mode MTP in notifications. Copy the necessary folders (DCIM, Download, Music) to your computer’s hard drive.
Then disconnect the old device and connect Redmi 9T. Transfer the saved files to the appropriate directories in the internal memory of the new smartphone. This method ensures that the files will be copied bit-for-bit without any compression or loss of quality.
Folder structure for copying:/DCIM/Camera - Photos and videos from the camera
/Download - Downloaded files
/Music - Audio recordings
/Documents - Documents and PDF
However, this method has a significant drawback: it does not transfer application settings, call history and widget placement. You will have to manually configure each service and application again, which can take considerable time.
What to do if the computer does not see the phone?
Make sure that the cable is working and supports data transfer, not just charging. Try a different USB port or install ADB drivers if the device is detected as unknown.
Data transfer via Bluetooth and Wi-Fi Direct
If you don’t have a cable at hand and don’t want to install additional applications, you can use the built-in communication protocols. Bluetooth is suitable for transferring small amounts of data, such as contacts or individual documents, but it is extremely slow for media files.
A more advanced option is to use technologies Wi-Fi Direct or Nearby Share, which are built into modern versions of Android. These protocols allow you to transfer files at high speeds without the need to connect to the same Wi-Fi network.
To activate the function on Redmi 9T open the quick settings panel and find the “Nearby” icon. On your old device, select the files, click Share, and select the discovered device. Confirm reception on the new smartphone.
- 🚀 High transfer speed (up to 20-30 Mb/s)
- 🔒 Encryption of the connection during transmission
- 📶 Does not require the Internet and router
This method is good for single-point transfers of heavy files, but is not suitable for a complete system migration. It does not know how to transfer messenger databases or system interface settings.
Features of transferring instant messengers and banking applications
The transfer of data from instant messengers, such as WhatsApp, Viber and Telegramdeserves special attention. These applications store correspondence history in separate databases, which are not always correctly copied by common utilities.
For WhatsApp it is best to use the built-in backup function. On your old phone, go to Settings → Chats → Chat backup and create a copy in Google Drive. On a new device, when you first launch the application, it will offer to restore history from the cloud.
Banking applications and services with two-factor authentication require a special approach. For security reasons, they do not transfer login information. You will have to re-enter your login, password and confirm your login via SMS or push notification on the linked number.
⚠️ Attention: Before deleting data from your old phone, be sure to check that you have successfully logged into all banking applications and instant messengers on the new Redmi 9T. Access to some services may be temporarily blocked if you frequently change devices.
In some cases, to transfer the history of correspondence between different operating systems (for example, from iOS to Android), paid third-party utilities are required, but when switching from Android to Android, standard tools are usually sufficient.
For messengers, always use their internal backup tools, since system ones backups may not save media attachments and voice message history.
Frequently asked questions and problem solving
Why did the data transfer freeze at 99%?
This is a common situation when transferring a large number of small files. Usually the process completes successfully if you wait 10-15 minutes. If the freeze lasts longer, try restarting both phones and starting the process again, selecting only those categories of data that were not transferred.
Is it possible to transfer data if the old phone is broken?
If the screen does not work, but the phone turns on and responds to clicks, you can try connecting a USB mouse via an OTG cable for control. If the phone does not turn on, you can only extract data through a service center or by connecting the memory to a PC in storage mode (if supported).
Is the data on the old phone erased after transfer?
No, all the methods discussed are copying methods. The data on the old device remains safe and secure. To remove them, you need to perform a manual reset to factory settings after you are convinced that the new smartphone is working successfully.
How to transfer the arrangement of icons on the desktop?
This function is supported only by the Mi Mover application, provided that the MIUI shell is also installed on the old phone. When switching from “pure” Android or another shell (OneUI, ColorOS), the arrangement of icons will be reset to the standard one.
Is it safe to transfer passwords through Mi Mover?
Yes, the connection between devices when using Mi Mover is encrypted. However, for maximum security of critical passwords (from banks, mail), it is recommended to change them after the transfer or check the activity of sessions in the account settings.
