Xiaomi smartphone owners often have to move the phone book when changing devices or after resetting the system. The standard shell MIUI or HyperOS has its own features of working with the address book, which differ from pure Android. Many users unknowingly store important numbers in the SIM card memory or locally on the device, which creates a risk of losing them.
Stored data in Google’s cloud storage is the most reliable method of protecting against accidental deletion. Synchronization allows you to instantly restore the list of callers on any gadget after authorization. Below we will discuss in detail the mechanisms of the system and how to force the information to the cloud.
The process takes only a few minutes, but requires careful privacy settings and choosing the right storage. It is important to understand the difference between local copies and cloud records to avoid confusion in the future.
Preparing a Google account and checking your settings
Before you start manipulating, you need to make sure that your device has a valid Google account added. Without authorization, automatic saving to the cloud will not work. Check if you have an account in the Settings → Accounts and Sync section.
If an account is present, check to see if a specific phone book option is activated. Android allows you to flexibly configure what data will be transmitted to the company's servers. Often, by default, this feature can be disabled to save traffic.
- 📱 Open your smartphone settings and find the "Accounts" section".
- 🔍 Select your Gmail email address from the list.
- ✅ Make sure the switch opposite the "Contact" item is activated.
- 🔄 Press the menu button (three dots) and select Sync".
⚠️ Note: If you use two-factor authentication, make sure that system services do not need to log in again. Sometimes security blocks background synchronization when you change your password.
Once synchronization is enabled, the system will automatically start to reconcile the local database with the cloud, a process that can take time if you have a large number of records, and a stable Internet connection at this point is critical to the successful completion of the operation.
Transfer of contacts with SIM-map and local memory
Users often store numbers directly on the SIM-You need to import a map or a device memory without linking it to the cloud, and you need to import it to Google Contacts, and this action will create a duplicate record in the cloud, making it available from other devices.
To start, open the standard Contacts app on your Xiaomi. Depending on the version of the MIUI shell, the interface may be slightly different, but the logic of the actions remains the same. You will need to find the management function or import / export data.
Click on the profile icon or the settings menu inside the app. Select the option "Import contacts." The system will prompt you to select the data source. SIM-phone-card.
Menu path: Contacts → Settings (three points) → Import/Export → Import from SIM-cardOnce you have selected a source, the system will ask where to store the imported data, and it's critical to choose your Google account over your Phone. If you choose Phone, the data will remain local and not be protected from loss when reset.
| Source of data | Where to keep | The result |
|---|---|---|
| SIM-map | Google Account | Full synchronization with the cloud |
| Phone memory | Google Account | Transferring local records to the cloud |
| VCF file | Google Account | Recovery from backup |
| SIM-map | Phone memory | No synchronization (risk of loss) |
☑️ Transfer checklist
Use of the Google Contacts app
Xiaomi smartphones have two applications for working with numbers: its own development MIUI and a standard application from Google. For full work with the cloud, it is recommended to use Google Contacts. This application provides better integration with the company's services.
If your device doesn't have a colored icon, you can download it for free from the Play Market Store. Once installed, open the app and log in to your profile. Only those posts that are linked to your account are displayed here.
The app has a "Current and Manage" feature, which allows you to find duplicates and combine them, and combining duplicates is an important procedure, because it cleans the phone book of any extra debris left over from the transfer.
You can also set up contact display here, so you can choose to only show records that are synced to Google, so you can visually separate important data from local copies that are not protected.
⚠️ Note: When connecting contacts, the system may request permission to change the data.Be careful if you have unique notes in the cards that you do not want to lose during the merger.
Why do you need two apps?
Creating a backup copy in VCF format
Even in the cloud, it's useful to have a local copy in the universal VCF format (vCard), which you can save to your computer, send yourself to the mail or transfer to another phone, which is a backup method of data protection.
To create a copy, open your contact settings. Select "Contact Export" and the system will tell you to choose the file format and the location of the save. It is recommended to choose the VCF format, as it is supported by all modern devices.
Save the file to internal memory or SD-Once you've completed the process, copy the file to a secure location, such as Google Drive, or to your computer, and it will allow you to recover your data even if your Google account is blocked.
- 💾 Open the settings of the Contacts application.
- 📤 Click "Export to.vcf file".
- 📂 Specify a save path (for example, a Download folder).
- 💻 Transfer the file to the PC or cloud.
Recovery from a VCF file is done via the Import menu. Select the saved file and specify the Google account as your destination. The system reads the file and adds all the records to the cloud, after which they are automatically synced.
💡
Save it. VCF file with date in the title, for example contacts_backup_2026.vcf. This will help you avoid getting confused with backup versions if you make them regularly.
Solving synchronization problems on Xiaomi
Xiaomi users often face aggressive battery optimization that can stop the synchronization process. MIUI/HyperOS seeks to save charge by closing background processes.This can lead to new numbers not being saved to the cloud on time.
To fix this, you need to set up autostart and work in the background for Google services. Go to Settings → Apps → All apps. Find in the list of “Google Play Services” and “Contacts”.
In each of these applications, you can find the Battery or Energy Saving section, and set the "No Limits" mode, which will prevent the system from forcibly shutting down synchronization processes.
Customization path: Settings → Apps → All apps → Google Play Services → Battery → No restrictionsAlso check for updates for Google Contacts. Older versions may contain errors that prevent servers from working properly. Updating through Play Market often solves process freeze issues.
⚠️ Note: Do not clear the data of the Google Play Services application unless absolutely necessary.This may cause the sync settings of all applications on the device to reset and require re-authorization.
💡
The main reason for the synchronization problems on Xiaomi is aggressive energy saving, and setting a “No Limits” mode for Google services solves 90% of the problems with delayed retention of contacts.
