Changing your smartphone or accidentally resetting your phone often causes panic when you find your call history is missing. For many Xiaomi and Redmi users, this information is critical, as the call log can store customer numbers, courier services or important contacts that were not recorded in the phone book. Fortunately, the Android ecosystem provides powerful tools for automatic backup, but the default settings on MIUI and HyperOS devices do not always activate this feature immediately.
The process of transferring data to Google's cloud service allows not only secure information, but also seamlessly restore it on any new device, just log in to your account. Unlike local backups, which take up space in memory and can be lost when a gadget breaks, cloud storage guarantees data security regardless of the state of the device itself.
In this article, we will take a closer look at all the steps of synchronization setup, look at possible problems, and suggest alternative methods for saving your call history. You will learn how to manage application access rights and why standard Google tools sometimes require additional intervention to work correctly on Xiaomi shells.
Preparing a Google account and checking access rights
The first and most important step is to ensure that your Google account is working correctly on your device. Often users ignore notifications to update agreements or confirm login, which blocks the ability to sync system data. Make sure that the phone has added the exact account you plan to use for backup and it is active.
Android requires explicit permission from the user to access the call log. Without this permission, even if synchronization is enabled, data will not be transmitted to Google servers. To check, you need to go to the system settings, find the Apps section and find the standard Phone application (often has a Google logo with a green handset).
- π± Open your smartphone settings and go to the App section.
- π Find the Phone app in the list (make sure itβs Google Telephony, not Mi Dialer).
- π‘οΈ Select Application Permission and make sure that Contacts and Phone are allowed.
- π Go to Battery Use and select No Limits mode so that the system doesnβt kill the synchronization process in the background.
It is important to understand that on different versions of the firmware MIUI or HyperOS, the name of the items may differ slightly, but the logic remains the same: the application-call should have full access to data and the ability to work in the background. If you use a third-party call, the settings should apply to it.
β οΈ Note: If you recently changed your Google account password, the sync may have stopped. Go to your account settings and re-enter your password to verify your identity.
Configure contact synchronization and call history
The main mechanism for porting the call log is tied to the Google Sync service. In modern versions of Android (starting with version 9), the call history and SMS can automatically be saved in the cloud if the appropriate option is enabled. However, on Xiaomi devices, this process sometimes requires manual activation through hidden or additional menus.
To start, you need to open the settings of the Google Phone app itself. Click on the three dots in the top corner of the screen and select Settings. Here you are interested in Backup or Sync Google Contacts. This is where the magic happens: the phone creates a cast of your data and sends it to the server.
If you see a message that backup is enabled but the date of the last backup is old, try switching the switch switch switch off/on. This will force a re-download attempt. Also convince modules that you have sync enabled in the general account settings: Settings β Accounts and Sync β Google.
βοΈ Checklist of synchronization settings
It's worth noting that synchronization only works when you have an active Internet connection. If you're using mobile Internet, the system can expect to be connected to Wi-Fi to transmit large amounts of data, although the call log usually weighs a little.
Using the Google One app for a full backup
For more reliable and complete data transfer, including not only contacts, but also detailed call history, Google recommends using the Google One app, an official cloud storage management solution that takes control of the backup process of the entire system, not just individual parts of it.
After installing and running the Google One app (often pre-installed on certified devices), go to the Warehouse tab. In the Backup section, you will see details of what data will be stored. include or exclude call history, SMS-messaging.
| Parameter | Description | Impact on memory |
|---|---|---|
| Contacts | Preservation of numbers and names | Minimum |
| A history of challenges | Journal of incoming/outgoing | Minimum |
| SMS-message | Textual communications | Low. |
| Multimedia (MMS) | Photo and video from messages | High. |
The advantage of using Google One is that you can see the exact size of the backup and the date it was created, which gives you confidence that the data is actually being updated, and the app will notify you if the backup has not been done for a long time.
