Activating Xiaomi Call Synchronization: The Complete Guide

Xiaomi smartphone owners often experience a situation where when changing devices or resetting their settings, their call history is lost, because by default the system may not save connection logs to cloud storage. The function that stores this information is called call synchronization, which allows you to automatically send incoming and outgoing calls to a server, from where you can restore them at any time.

Understanding what Xiaomi call sync is is critical to preserving your digital history. Without this setting, when you buy a new phone or flash your current phone, you will be left with no record of who you called and when. Today's MIUI and HyperOS shells offer flexible tools to manage that data, allowing you to choose your storage source.

In this article, we will take a closer look at how the Chinese brand’s cloud services work, as well as how to integrate with the Google ecosystem, learn how to set up automatic backups, what the difference is between on-premises and cloud storage, and how to avoid common mistakes that lead to loss of contacts.

What is synchronization of calls on Xiaomi devices

Call synchronization is a background process that copies call logs and contact data into secure cloud storage. On Xiaomi, Redmi and POCO smartphones, this process can be done in two main ways: through your own Mi Account account or through a Google profile, and the choice of method affects where your data will lie and how easily it will be restored on a device of another brand.

When you activate this feature, the system creates timestamps for each communication event, and if you delete a number from your phone's call history but the sync has already passed, the record will remain in the cloud, and this acts as an insurance against accidental registry cleanup, and the call log becomes accessible from any device that logs into your account.

⚠️ Note: If you are using public Wi-Fi networks without protection, transferring call log data to the cloud may be potentially vulnerable.

It's important to distinguish between contact synchronization and call history synchronization. Contacts are the numbers and names themselves, and call history is the chronology of your actions. Often users customize the former while forgetting the latter, which leads to a loss of context when changing gadgets.

Benefits of Using Mi Cloud to Save Call History

Using the native Mi Cloud offers a number of benefits for Xiaomi ecosystem owners, and unlike standard solutions, integration is done at a deep system level, which means that history recovery is faster and does not require additional actions to import files.

The key advantage is that you can selectively restore, so you can decide what to return to your device: contacts only, SMS only, or call logs only, which saves traffic and time, especially if the total backup is large.

• 📱 Free 5GB of space is available, enough to store thousands of call records and contacts in text format.
• 🔄 Automatic data update occurs in the background when connected to Wi-Fi, without consuming battery power excessively.
• 🔒 Data is encrypted during transmission, ensuring the confidentiality of your correspondence and calls.

Another important aspect is cross-platform within the brand: if you move from Xiaomi Mi 11 to the new Xiaomi 14, the migration of data through the Mi Cloud will be as smooth as possible, the system itself recognizes the backup structure and offers to restore exactly the data that is not on the new device.

💡

Check the amount of space occupied in Mi Cloud regularly. If the storage is overflowing with photos, call synchronization may stop and new records will not be saved.

Integration with Google Account: Should I Switch?

Many users prefer to rely on Google services as more versatile. Indeed, if you plan to switch to a smartphone of another brand in the future, such as Samsung or Pixel, keeping your call history in your Google profile will make migration easier.

Synchronization through Google often works less transparently for call history than for contacts. While contacts are updated instantly, the call log may require manual confirmation or operation of specialized applications from Google, such as Google Phone and Google Contacts. The standard MIUI dialer is default-focused on Mi Account.

To activate this method, you need to make sure that your Google account settings are ticked against the contact box, and your call history is often synced separately or through Google’s Phone app, and Google Assistant and other Google services also use this data to improve speech recognition and spam filtering.

If cross-platform is important to you, Google is worth it, but if you live in the Xiaomi ecosystem, the native cloud provides more stable Find Device and lock lost phone, as these services are tied to Mi Account.

Step-by-step: how to enable synchronization through Mi Account

The process of activating sync on Xiaomi smartphones is intuitive, but requires careful choice of options. First, make sure you have an active Mi Account. If not, sign up for the settings menu or through the browser.

Go to the main settings menu of the device. Find the section, which is usually called "Mi Account" or "Xiaomi Account", which is located at the top of the list. Click on it and enter your authorization details if you have not signed in yet.

Once you log in, select Cloud, where you'll see a list of apps and data available for sync, find Contacts and Calls (or Call log) in the list, and move the sliders to On.

The system can suggest combining local data with cloud data. You can agree to this action if you want to save all current records. Once enabled, the function will start working. You can check the status by opening the Security app or going back to the cloud menu, where you will specify the time of the last sync.

Solving common synchronization problems and errors

Despite the fact that processes are fine, users can encounter errors, most often the problem lies in an unstable Internet connection or crowded cloud storage. If synchronization is “hangy”, try switching from Wi-Fi to mobile Internet and back.

Another common cause of failure is time and date desynchronization, and if your device is running an incorrect time, the security server may block the connection as potentially dangerous, and check if the date and time settings are in Network Auto Detection mode.

⚠️ Note: If you have frequent sync failures, don’t try to turn the function on and off all the time.This can lead to duplicate contacts.

If the problem is with duplicate numbers, use the “Combine Repetitive Contacts” feature built into the Contacts app on Xiaomi, which analyzes names and numbers, suggesting that matching entries be combined into one card, which also facilitates the synchronization process.

In some cases, forced service stops help. Go to Settings → Applications → All apps, find “Sync Mi Cloud” (or Mi Cloud), click “Stop”, and then manually start sync again through the account menu.

Recovery of data after resetting or changing the device

The most important thing is when you need to sync to restore, when you set up a new phone or after you reset it will suggest you restore the data from the backup, choose the source Mi Cloud or Google.

If you're recovering data from Mi Cloud, the process may take some time depending on the speed of the Internet. Don't interrupt the process and keep the screen on. Once you've completed the check, you'll see that your call history and contacts have appeared in the respective apps.

For selective recovery, go to i.mi.com from a computer or other phone. log in, select Contacts or Cloud, and find a recovery option. You can upload the data in vCard format, which can then be easily imported into any smartphone.

💡

Regularly checking sync status (once a month) ensures that your data is in place at a critical time, rather than in an outdated backup of a year ago.

If you delete a contact on your phone and sync is over, it will also be deleted on the server, however, in the cloud service cart (if this feature is available in your version of MIUI), deleted items can be stored for up to 30 days.
