Changing a smartphone, especially within the same ecosystem, is often perceived as a stressful moment, associated with the risk of losing important data. However, owners of the Chinese brand devices are in a better position, since MIUI and HyperOS offer deep synchronization capabilities.
The data migration process can take anywhere from a couple of minutes to half an hour, depending on the method chosen and the amount of information stored. Modern tools allow you not only to copy names and numbers, but also to save your call history, SMS and even the location of icons on your desktop. It is important to choose the method that suits your current situation: the presence of the Internet, the state of your old device or personal preferences for privacy issues.
In this article, we will take a look at all the current methods, from cloud synchronization to local transfers over Wi-Fi. You will learn how to avoid duplicates and what to do if standard tools fail. The most reliable way to fully migrate is to use the built-in Mi Mover app, which copies data directly between devices without compressing quality. Let's start to study each option in detail.
Using the Mi Mover app for quick migration
The most efficient and quick way developed specifically for the Xiaomi ecosystem is to use the pre-installed Mi Mover app.This tool creates a direct Wi-Fi connection between the two devices, which ensures high data rates without using Internet traffic.The process is fully automated and requires minimal user intervention, making it an ideal choice for most scenarios.
To get started, make sure both smartphones are at least 50 percent charged and connected to the same Wi-Fi network, although the app can create its own hotspot. On an old phone, run Mi Mover through the settings menu or by finding an icon in the Tools folder. When you first start, the system will request permissions to access contacts, storage and location - these must be provided for proper operation.
⚠️ Note: During the data transfer process, device screens may go out, but do not block them completely and do not switch to other applications so as not to break the connection.
On the new device, select Reciever and on the old one, Sender. QR-If you have a code or manual connection to the network, you'll start analyzing the data, you can select only contacts, or you can add photos, apps, and system settings, and the algorithm allows you to pause the process in the event of an incoming call, and then continue from the stoppage.
☑️ Preparation for transfer via Mi Mover
Sync with Mi Cloud and Google account
Cloud technology has become the de facto standard for backup, and Xiaomi’s ecosystem is no exception: Using Mi Cloud allows you to store contacts in secure storage, which can be accessed from any device by logging in to your account, ideal if your old phone is already sold, lost or inoperable, but sync was enabled in advance.
To check the status of the save, go to Settings → Mi Account → Sync. Make sure the switch opposite the item "Contacts" is active. If you see the status "Synced", then your data is safe. On the new phone, just log into the same Mi Account, and the phone book will fill in automatically in the background.
The alternative is Google Contacts, which is often a more versatile solution, especially if you plan to change your smartphone brand in the future. All Android devices by default offer to save a number when you create it using a Google account. You can check for a backup by going to contacts.google.com from a computer or any browser.
- 🔄 Automatic update of data on all devices in real time.
- 🛡️ Protection against data loss in case of physical failure of the device.
- 🌐 Possibility of Recovery of Contacts via Web Interface.
- ⚙️ Flexible timing frequency settings depending on traffic.
Export and import via VCF file
The method of creating a local copy of a phone book in.vcf (vCard) format is the gold standard of compatibility, supported by all operating systems, email clients and phone books, and if you don’t have access to the Internet or are afraid to transfer personal data through the cloud, creating a backup file is the best solution.
To create a copy, open the standard Contacts app on the old Xiaomi. Click on the menu (three dots or a hamburger menu) and select "Import and export." Next, select "Export to Storage." The system will create a file, commonly called contacts.vcf or 00001.vcf, at the root of internal memory or the MIUI/backup/contacts folder.
The resulting file must be transferred to a new smartphone, which can be done via Bluetooth, messengers (Telegram, WhatsApp), email or simply by flipping over the phone. USB-You just open the file on the new device, and the system automatically prompts you to import the records in the memory of the phone or the selected account.
⚠️ Note: When importing from the file VCF Please be careful not to create duplicates if some of the contacts have already been saved. SIM-card or other account.

Data transfer from SIM-map
Despite the development of digital technologies, SIM-The card remains a popular, albeit limited, medium, and is suitable for older phones or situations where software methods don’t work. The main limitation is the amount of SIM card memory: it usually only holds names (often cropped to the top). 10-15 characters) and one number per contact, ignoring additional phones, email addresses and photos.
The copying procedure for an old phone is simple: go to the contact settings, select "Import / Export" and click "Import from" SIM-After that, all the records will be stored in the memory of the device. To transfer them to the new Xiaomi, paste the SIM card into it, then select "Export to" in the contact menu. SIM-map (on the old) and "Import with the SIM-Maps (new) or copy your contacts to your Google account.
This is often used as an intermediate step, for example, if you have a button phone or a device with a damaged screen, extraction is a step. SIM-However, for a full migration between two smartphones Xiaomi better use more modern methods that preserve the entire data structure.
| Parameter | SIM-map | Google Account | Mi Mover |
|---|---|---|---|
| Photo preservation | No. | Yes. | Yes. |
| Several rooms. | No (usually 1) | Yes (no restrictions) | Yes. |
| Internet is required | No. | Yes (for synchronization) | No (locally) |
| Speed. | Low. | Medium | Tall. |
💡
Before extraction SIM-The cards make sure you know. PIN-code (if installed), otherwise, when installed in a new phone, the card may be blocked after three unsuccessful attempts to enter.
Solving Duplicate Contact Problems
A common problem with changing phones frequently or using multiple synchronization methods is the appearance of duplicates. A phone book can contain dozens of entries "Mom" or "Work" with different numbers or the same. MIUI has a built-in cleaning tool that makes life much easier for the user.
To eliminate chaos, open the Contacts app, go to the settings (three dots), and find the option "Clean Duplicates" or "Combine Repeated Contacts." The system will analyze the database, find records with the same names or numbers, and suggest combining them into one card. This is safe: information is not lost, but only structured.
If the automatic cleanup didn't work, you can use the web version of Google Contacts, and there's a Find and Combine feature that works even more effectively than on your phone, because it uses Google's powerful search algorithms, and once you clean the site, the changes will automatically pull up to your smartphone when you have the Internet.
- 🧹 Regular cleaning of duplicates speeds up search and dialing.
- 🔗 Combination of cards keeps the history of calls and correspondence.
- 📂 Grouping contacts improves the organization of the address book.
- 🚫 Deleting Empty Records Frees Up Space in the Cloud.
Safety and recovery after discharge
Data portability is also a security issue. Before you hand over your old phone or scrap it, make sure all contacts have successfully migrated to the new device. A full reset to the factory settings (Wipe Data) on the old Xiaomi will irreversibly delete all local copies if they were not synced to the cloud.
After setting up a new phone, it is recommended to make the first full backup through Settings. → The phone. → Backup and Restore: Select to create a local copy on an internal drive or an external drive. USB-This will create a point of return in case something goes wrong during the initial setup.
Also worth checking your contact visibility settings. The Contacts app has a display filter: make sure you check the All Contacts box, not just Phone or SIM, so you can see the full picture of your address book. Regularly checking the relevance of backups (at least once a month) will keep you from unpleasant surprises in the future.
💡
Regular sync with Google or Mi Cloud takes seconds, but saves hours of time and nerves in the event of a device being lost or broken.
