Synchronizing calls on Xiaomi: how to activate and configure the function correctly

Have you ever encountered a situation where your Xiaomi call history suddenly disappears after resetting or flashing? Or do you want your call log to automatically sync across multiple devices? The call synchronization feature in Xiaomi smartphones solves these problems, but many users are unaware of its existence or do not know how to set it up correctly.

In this article, we will discuss in detail what is call synchronization on Xiaomi, how to enable it through standard settings. MIUI, What alternative methods exist (including cloud services and third-party applications), and consider common errors and how to fix them. MIUI 14/15 and the new HyperOS, where the interface settings have undergone changes.

What is call synchronization and why is it necessary?

Call sync is a feature that automatically saves incoming, outgoing and missed calls to the cloud or Xiaomi servers, and then restores it when you change your device, reset your settings or install a new firmware. Without this option, all call records are stored only in the phone’s local memory and can be lost.

The main advantages of the function:

• 🔄 Recovering History After Resetting or Replacing a Smartphone
• 📱 Synchronization between devices (if you use multiple Xiaomi phones under the same account)
• 🔒 Backup of important contacts and calls
• ⏱️ Time savings – no need to manually transfer the call log

For example, if you switch from Redmi Note 12 to Xiaomi 14 Pro, the first time you log in to your Mi Account, the system will suggest you recover your call history — but only if you have synced in advance.

How to enable call synchronization through MIUI settings

The standard way to activate synchronization is through the MIUI settings menu. The interface may vary slightly depending on the shell version, but the overall algorithm remains similar. Let's take MIUI 14 and HyperOS as an example.

Steps to include:

1. Open the Settings app (cog icon).
2. Go to Accounts and Sync (or Mi Accounts in older versions).
3. Select Mi Account and log in if you haven’t already.
4. Slip on the item Synchronization of data.
5. Find the call log (or call history) option and activate the slider.

Once turned on, the system will start uploading existing records to the cloud, which can take anywhere from a few minutes to an hour — depending on the number of calls in your history, and if you have more than 5,000 records, the sync may be interrupted, in which case it is recommended that you first clean the call log manually.
