Changing your smartphone often becomes stressful when you realize you’ve lost your phone history or important contacts on your old device. In the Xiaomi ecosystem, this process is greatly simplified by built-in backup mechanisms that work at the system level. Call synchronization is not just about moving your phone book, but about comprehensively preserving your entire communications history, including the time, duration and status of incoming and outgoing calls.
Many users mistakenly believe that it is enough to move SIM-So, this is a map, so that all the data magically comes out on the new machine, SIM-The card has a very limited amount of memory and is not designed to store call history or multimedia data. To work properly, you need to set up cloud services such as Mi Cloud or Google account, which will become a reliable repository of your digital life.
In this article, we will discuss how to properly activate the sync function, what is the difference between Xiaomi and Google services, and how to avoid common errors when transferring data. You will learn how to set up automatic history saving so that even if you lose your phone or accidentally reset your information remains safe.
The principle of cloud synchronization on MIUI and HyperOS
The key to Xiaomi’s smartphone data storage is the constant exchange of information between the device and the remote server. When you make or receive a call, the system in the background creates a record of the event. If the feature is activated, this record is instantly or when you connect to Wi-Fi is sent to your personal cloud profile.
The key difference is that data streams are separated, and contacts and call history can be synchronized separately, meaning that the user has the flexibility to store phone numbers in one place (like Google) and call history in another (Mi Cloud), so that the flexibility is to be independent of one service provider and backup in different places.
It's important to understand that the process is not real-time every second unless you have an instant transfer mode that consumes more battery, and usually the system waits for a Wi-Fi connection or the moment the phone is on charge so as not to interrupt your current activities and not to waste mobile traffic.
⚠️ Note: If you change region frequently in your Mi Account settings, your call history may not sync as servers in different countries may have different data retention rules.
Google has traditionally been strong in managing contacts, but its functionality to save a call log is limited and depends on the version of Android and the settings of Google’s system itself. At the same time, Mi Cloud is sharpened for deep integration with the shell. MIUI/HyperOS and retains a complete call history, including missed calls and duration of conversation.
Let’s look at the main differences in the table below so you can choose the best option for yourself:
| Parameter | Mi Cloud (Xiaomi) | Google Contacts |
|---|
| Keeping a call history | Full (time, date, duration) | Partial or absent (depending on the OS) |
| Free storage capacity | 5GB | 15 GB (total with Gmail and Photos) |
| Integration with the system | Deep, native. | Basic, through system services |
| Recovery on iPhone | Requires Mi Cloud for iOS | Automatically when logging into your account |
For Xiaomi appliance owners, using the native cloud is often more convenient, especially if you plan to buy the phone again from the brand in the future.Recovery from the Mi Cloud is faster and restores not only the numbers, but also the context of communication.

How to enable call synchronization through Mi Cloud
Activating backups through Xiaomi services is the first step to securing your data. The setup process is simple enough, but requires care to select the right settings. Make sure you have an active Mi Account and are logged in.
To start, open the standard Phone app or go to the general settings of the device. You need to find the section responsible for cloud services. The path may vary slightly depending on the firmware version, but the logic remains the same.
Follow the following steps:
- 📱 Go to Settings and click on the top plaque with your Mi Account.
- ☁️ Select Mi Cloud (or "Cloud").
- 📞 Find the call history switch in the list and activate it.
- 🔄 Click on “Sync Now” to force the process to start.
Once this feature is enabled, the system will automatically download the call history every time it connects to the network, and you can check the status in the same menu, which will indicate the time of the last successful synchronization.
What to do if there is no space in the cloud?
If 5GB of free space is full, sync will stop. You can delete old voice recorder backups or screenshots from the cloud, or purchase additional storage in the subscription. Setup backup via Google Account Although Mi Cloud is convenient for the Xiaomi ecosystem, it is not worth ignoring Google's capabilities. This is especially true if you plan to switch to another manufacturer's smartphone in the future. Synchronization through Google provides cross-platformity of your data. In modern versions of Android and the HyperOS shell, Google Sync is put on a separate menu. Here it is important to check what types of data the giant is allowed to transfer to transfer to the server by default for the traffic history. To set up this process: 🔍 Open your phone’s settings and scroll down to Google. 📲 Select the Synchronization or Backup menu. ✅ Make sure that the Google Contacts switch is active. 📞 Find the Call History item (may be called the Call log) and turn it on. It's worth noting that Google can request permission to access the Call Log on first turn on. This is the standard Android security procedure, confirming that you allow the system to transfer this data. ⚠️ Note: When you reset your settings to the factory (Hard Reset), the data in Google is stored, but the local history on the phone will be deleted. Restoration will only occur after you enter your Google account at the first setting. If you need to move data from your old phone to a new Xiaomi right now, the cloud can be too slow, especially if your call history has thousands of records. In this case, the specialized Mi Mover app comes to the rescue, which transmits data over a direct Wi-Fi channel. The good thing is that it does not depend on the speed of the Internet and the amount of your cloud storage. The application creates a direct connection between the two devices. This is the ideal option for the initial setup of a new smartphone. The transfer process is as follows: Install the Mi Mover application on both devices (on the new Xiaomi it is built into the "Additional" section in the settings in the new one "I will get the new one" and the old one "I will receive the "I will send the new one". Scan it. QR-code or connect to the Wi-Fi network you have created. In the data list, be sure to select System Data and Call History. 20-40 MB/s, which allows you to download years of call history in minutes, and when you finish the process, the new device will have all the history that was on the old device, and the solution: why calls don't sync, and even though the system is fine, users sometimes encounter errors. The data is not updated, or the status is in "Grid Wait" mode, most often the problem is in the settings of energy saving or unstable Internet. MIUI She's known for her aggressive work with background processes to save battery life, she can kill the synchronization process if she thinks it's unimportant, and it's worth checking if the cloud is out of space. Main causes of failures: 🚫 Background activity restriction: Check if traffic restriction is worth it for system applications. 🔋 Energy savings: Ultra-energy saving mode can block synchronization. 📡 Date and time issues: Wrong date on phone causes security certificate conflict. 🔒 Two-factor authentication: Sometimes you need to re-sign in after changing your password. 💡If sync is stalled, try turning off and re-enable the sync switch and then restart the device. In some cases, cleaning the Mi Services or Google Play Services cache helps. → Annexes → All applications, find the desired service, select "Memory" and click "Clear cache". FAQ: Frequently Asked Questions: Are recordings of conversations synchronized (dictophon recordings)? No, standard call history synchronization stores only metadata (who, when, duration). Audio recordings of conversations are stored separately in the voice recorder folder and require a separate synchronization setting in the Dictophone app or through Mi Cloud in the Audio section. What happens to the call history if I delete the Mi Account from the phone? When I delete the account from the device, the local history on the phone will remain, but the ability to sync new data will disappear. Data already uploaded to the cloud will also remain there until you delete it through the web interface or restore the data to the cloud, however, if you can not completely restore the history to synchronize it from the device before the phone. Does the call history take up a lot of space in the cloud? No, text history takes up negligible space. Thousands of records will take up only a few kilobytes or megabytes. The cloud is usually dominated by photos, videos and app backups.
