Modern Xiaomi smartphones running MIUI or HyperOS shells offer users several options for saving a phone book.This creates a certain confusion, especially for those who have switched from push-button phones or other operating systems. Choosing the right storage location is not just a matter of convenience, but a necessity to ensure the security of your data in the event of a device loss or failure.
By default, the system often suggests that you save a number in several places at once, but not all of them are equally reliable, SIM-A map, a Google account, or a Mi Cloud service all have their own technical features and limitations, and understanding these differences will help you avoid situations where, after resetting your settings or buying a new smartphone, your phone book is empty.
In this article, we will discuss all available options in detail, analyze their pros and cons, and give clear instructions on how to configure automatic synchronization. SIM-The card is considered an archaic method and how to properly set up a backup so that your data is always at hand.
Main locations for contact storage in MIUI and HyperOS
When you create a new entry in your phone book, the system asks you to choose the target storage, which is the first and most important filter that determines the fate of the data entered. Xiaomi smartphones usually have three main areas: Google account, Mi Account and local device storage.
The most reliable and recommended option is a Google account, where all the data entered is instantly sent to Google’s servers and linked to your email, which provides cross-platform functionality, allowing you to see your numbers by logging in from any other Android smartphone or browser on your computer.
The second option is the Mi Account, Xiaomi’s own cloud storage, which is convenient for those who are deeply integrated into the brand’s ecosystem and use various devices such as tablets or Mi laptops. However, for most users, the Google bundle remains more versatile.
- 📱 Google Account – Maximum Data Compatibility and Security.
- ☁️ Mi Account is convenient for Xiaomi ecosystem, but less universal.
- 📁 Phone – local storage, risk of data loss during reset.
- 💾 SIM-A map is an outdated method with strong limitations.
⚠️ Warning: Keeping contacts only in the phone’s memory (the “Device”) makes them vulnerable. If the motherboard breaks or is accidentally reset to factory settings, it will be almost impossible to restore this data without a preliminary copy.
Why you should not keep contacts on SIM-map
Many users continue to keep numbers on the site. SIM-It's a very reliable method, and it's true that when you change your phone, you're going to have to keep your numbers going, but it has some critical flaws that in today's world outweigh its only advantage.
First of all, SIM-The card has a very limited memory and an outdated file system, and it is not designed to store additional information: you can not add a photo, second number, email, address or social network link to the contact. SIM-Long names are cut off and special symbols are replaced with question marks.
Second, the physical medium is subject to wear. SIM-And unlike cloud services, where data is duplicated on multiple servers, your phone book exists in a single instance on a small piece of plastic.
Use of the SIM-Today, only one case is justified for cards as the main storage: if you temporarily move the card into a button phone or smartphone without access to the Internet for a quick transfer of the number base.
Benefits of syncing with Google Account
Google sync is the gold standard for Android devices, including Xiaomi. When you activate this feature, your contacts become part of your digital profile.This means that even if your Redmi or Poco smartphone falls into the water and stops turning on, you will only lose hardware, not information.
To set up, go to Settings → Accounts and Sync → Google. Here, make sure that the switch opposite the Contacts item is activated, and then the system will automatically send any changes to the cloud in the background, consuming minimal traffic.
A huge plus is the ability to manage contacts through the web interface. By going to contacts.google.com, you can:
- ✏️ Edit names and numbers from the computer keyboard.
- 🗑️ Massively remove duplicates with built-in tool.
- 📤 Export the entire database in format CSV or vCard for transfer to other services.
- 🔄 Restore remote contacts in the last 30 days.
💡
Use the Undo Changes feature in Google Contacts if you accidentally delete an important group of numbers or confuse data when synchronizing, which allows you to roll back the base state 24 hours, a week or a month.
Google also uses intelligent algorithms to combine duplicates, so if you have two Ivans in your notebook with the same numbers but different names (e.g., one in Latin and the other in Cyrillic), the system will suggest combining them into one card, clearing the list of garbage.
Using Mi Cloud for Backup
Xiaomi smartphone owners have access to their own cloud storage, the Mi Cloud, which is deeply integrated into the MIUI shell and allows you to create full copies of the system, including contacts, messages, notes and even placement of icons on the desktop.
To activate contact sync via Mi Cloud, go to Settings → Mi Account → Xiaomi Cloud → Sync. Here you can flexibly configure what data should go to the cloud. For contacts, you can create multiple copies, which is convenient for separating personal and work phone books.
One of the unique advantages of Mi Cloud is the ability to restore remote contacts through a special web interface i.mi.com. Even if you cleaned the shopping cart on your phone, the cloud can store data for up to 30 days. This serves as an excellent additional layer of protection along with Google.
| Comparison parameter | Google Contacts | Mi Cloud | Phone memory |
|---|---|---|---|
| Memory capacity | 15 GB (shared with mail) | 5GB (free) | Depends on the smartphone. |
| Access to PC | Yes (full functionality) | Yes (limited) | No (only via USB) |
| Synchronization | Automatic, instantaneous. | Automatic, Wi-Fi. | Absent. |
| Risk of loss | Minimum | Low. | High-pitched |
⚠️ Warning: Free space in the Mi Cloud is limited to 5 gigabytes. If you plan to make full backups of the system with photos and videos, this space may not be enough. Contacts take up negligible space, but keep an eye out for the overall limit.
Instructions: how to transfer contacts to the new Xiaomi
If you just bought a new Xiaomi smartphone and want to move contacts from your old device, there are a few effective ways to do it, and the easiest way to do that is to use the data migration feature built into the system.
When you first turn on a new phone, the system will suggest you set up the device, select Restore from the Cloud or Import from another device. If the old phone is also Android-based, just scan. QR-code and the transfer process will start.
☑️ Checklist before data transfer
Alternatively, import via vCard. On an old phone, log in, select Export, and save the file to.vcf on your internal drive, or send it to your messenger/mail. On your new phone, just open the file, and the system will suggest importing all the records.
For users switching from iPhone, Xiaomi provides the Mi Mover app (or uses a built-in wizard when configuring iOS), which allows you to transfer contacts, photos and videos wirelessly, the process takes from 10 to 40 minutes depending on the amount of data.
What to do if your contacts are not synchronized?
Solution: duplicates and missing numbers
One of the common problems with using Xiaomi smartphones is the appearance of duplicate contacts. This happens when the same number is stored simultaneously in the memory of the phone, on the phone. SIM-The system sees them as different records, creating chaos in the phone book.
To solve this problem, the standard Contacts app has a built-in tool: click three dots in the corner of the screen, select Contact Organization (or Contact Management), and find Combine Duplicates. The system will automatically find matches and prompt them to merge.
Another common situation is that contacts are lost after updating the firmware or resetting, and in 90% of cases, they are not gone, but simply disappeared from the display, go to the contact display settings and make sure that the “All Contacts” checkbox is ticked or the specific Google account where they are stored is selected.
- 🔍 Check the display filter in the contact app.
- 🔄 Forced to start synchronization in account settings.
- 🗑️ Use the web version of Google Contacts to search in the archive.
If the numbers have been deleted, don't panic. Google Contacts has a shopping cart where deleted records are stored for 30 days. Go through the browser, click on Recycle Bin and recover the necessary records with one click.
💡
Regularly checking the synchronization status and the absence of duplicates is a guarantee that your phone book will always be up-to-date and accessible from any device.
