Synchronizing health data across ecosystems is often a real headache for smart gadget owners. Xiaomi users often find that Mi Fit’s native app or its newer version of Zepp Life doesn’t provide the deep analytics available in Google’s services. That’s why integrating the Chinese brand’s fitness trackers and watches with Google Fit’s platform remains a pressing issue, allowing them to combine all the statistics in one place using powerful analytics algorithms from the search giant.
The main challenge is that direct synchronization between Xiaomi Wear (or Mi Fitness) and your Google account is often missing or incorrect due to regional constraints. You’ll have to use a bunch of intermediary apps to act as a bridge to transfer step, pulse and sleep data. Despite the apparent complexity, the setup process takes only a few minutes if you follow the algorithm clearly and configure the access rights correctly.
In this article, we will explore all possible ways to combine data, including using the official Health Sync app and alternative solutions. You will learn how to set up automatic metrics transfer so that you see the latest statistics in the usual interface every morning. We will also touch on the important nuances of the background processes on Android, which often block syncs.
Why you should combine data from Xiaomi and Google
Using a single activity history platform offers a number of undeniable advantages over disparate applications, first of all, Google Fit has more advanced algorithms for calculating Heart Points, which take into account the intensity of the load, not just the number of steps, which allows you to more objectively assess the effectiveness of training, whether it is running, cycling or yoga.
In addition, many third-party food and training apps require a connection to Google services, ignoring a direct connection to Xiaomi Wear. By combining accounts, you automatically expand your tracker functionality to access hundreds of compatible services, which is especially important for those who use Mi Scale smart scales or other smart home devices.
It is important to understand the difference between control applications. Xiaomi Wear (often called Mi Fitness) is designed for newer watch models such as the Mi Watch and Mi Band 7/8. Older models use Zepp Life (formerly Mi Fit). The synchronization mechanism is similar in both cases, but the interfaces may differ.
Another plus is backup: Google account data is stored securely and can be restored when you change your smartphone to any other Android device, which eliminates the risk of losing years of statistics when a Xiaomi device breaks down or sells.
Preparing devices and accounts for synchronization
Before you start setting up the bridge between apps, you need to make sure that the underlying infrastructure works correctly.The first step is to install and configure the main application for your device - Xiaomi Wear or Zepp Life. The tracker must be paired with a smartphone and the data must be successfully displayed in the native application.
You need to have a Google account that has Google Fit connected to it. If you've never used it, download it from Google Play and log in to your profile. The initial setting is minimal: just specify height, weight and age to calculate calories correctly.
- 📱 Make sure your smartphone has Google Play Services installed and is updated to the latest version.
- 🔋 Check the charge of the watch and phone – the setup process may take time, and the defunct device will interrupt the synchronization.
- 🌐 A stable Internet connection is required for authorization in all services at the same time.
The critical point is permission. Android strictly controls background activity, so the system needs to "allow" data to be transferred between applications. Without this step, synchronization will only occur when the synchronizing application is open.
☑️ Checking before synchronization
⚠️ Attention: On smartphones Xiaomi with a shell MIUI HyperOS or HyperOS is aggressively power saving.Be sure to add all participating applications (Xiaomi Wear, Google Fit, Health Sync) to the battery exclusion list before you start setting up and enable auto-run.
Main method: using Health Sync
The most reliable and time-tested way to transfer data is to use a specialized aggregator application, a niche leader called Health Sync, which supports synchronization with Zepp Life, Mi Fitness (Xiaomi Wear) and dozens of other trackers by feeding data to Google Fit.
The setup process starts with downloading the app from the Play Market Store. After installation, run the app and select the data source. You can find your choice in the list: Zepp Life (for older models) or Mi Fitness (for new ones).
The app will ask for permission to access your health data, which is normal, because that's what it's designed to do. You'll need to log in to your Xiaomi account and your Google account inside the Health Sync app, and after you successfully link up, you'll be able to choose which metrics to share.
| Parameter | Zepp Life (Mi Fit) | Mi Fitness (Xiaomi Wear) | Google Fit |
|---|---|---|---|
| Supported devices | Mi Band 1-6, old watch | Mi Band 7-8, Mi Watch, new watch | All Android devices |
| Synchronization of sleep | Yes (via Health Sync) | Yes (via Health Sync) | Yes. |
| Pulse at rest. | Yes. | Yes. | Yes. |
| The cost of synchronizer | Paid (there's a test) | Paid (there's a test) | Free of charge. |
It’s important to note that Health Sync is a paid application after a trial period (usually 7 days), but it’s a price for stability. Free counterparts often stop working after updating the API of Google or Xiaomi services. Investing in reliable software saves nerves and time.
What if Health Sync doesn’t see the data?
Alternative methods and aggregator applications
If the basic method doesn't work for some reason, there are alternatives, and one popular option is the Syncer for Mi Band app, which specializes in Xiaomi and Amazfit devices, providing flexible synchronization frequency settings.
Another option is to use the Gadgetbridge app, which is an open-source project that doesn't require a cloud sign-up and works entirely locally on your phone, but it's harder for a beginner to set up, and support for new device models can come with a delay.
- 🔄 Syncer allows you to adjust synchronization intervals (e.g., every 15 minutes).
- 🔒 Gadgetbridge guarantees privacy, as data is not sent anywhere except your phone.
- 📊 Some applications allow you to export data in.csv or.tcx format for manual import.
For advanced users with ADB (Android Debug Bridge) skills, there is a possibility of manually embedding certificates to intercept traffic, but this method is extremely unstable and requires constant reconfiguration when updating applications.
⚠️ Note: Using third-party aggregator apps requires them to access your biometric data. Only choose proven high-ranking solutions on Google Play, such as Health Sync or Syncer.
💡
For maximum autonomy in the Health Sync app, set the interval to check new data to "Every 15 minutes" or "Every hour" to prevent the battery from running out by constantly polling the tracker.
Setting up access rights and energy saving
The most common reason synchronization stops working is aggressive battery optimization in Android, which simply kills the synchronizer process by thinking it's an unnecessary resource user, and to avoid that, you have to manually change the settings for each application involved.
Go to Settings, find the Apps, and select Health Sync (or equivalent). Go to Battery or Energy Saving. Select No Limits or No Limits mode. This is a critical step that will not allow automatic sync to work without.
You also need to check permissions. In the same app settings menu, find the Permissions section. Make sure the app is allowed to:
- 🏃♂️ Access to physical activity (steps, pulse).
- 📍 Location access (required for some Google Fit features to work correctly).
- 🔔 Notifications (so you can see the synchronization status).
Xiaomi devices also need to enable auto-start. Find the Security app → Permissions → Auto-start and activate the switch for your synchronizer. This ensures that the service starts immediately after the phone is turned on.
💡
Without setting up the “No Limits” mode in the battery partition, no sync application will be able to run stably in the background on Android.
Solving Typical Problems and Errors
Users often encounter errors during the setup process, and one of the most common is “authentication error” or “failed to connect to the server,” which is often because application passwords or access tokens are outdated.
To solve this problem, try to break the connection in the sync app and reconnect accounts, sometimes it helps to fully log out of your Google account in your phone settings and re-sign in, but this is a radical measure.
If the data is transmitted but not all (e.g. no sleep), check the settings in the source app. Zepp Life or Xiaomi Wear should have sleep monitoring enabled and the data should be visible there. If it is not in the native app, there is nothing to sync.
| Problem. | Possible cause | Decision |
|---|---|---|
| Data not updated | Locking the system | Remove battery restriction, enable auto-start |
| The Mistake of Logining in Xiaomi | Password/token change | Re-link your account to Health Sync |
| No steps in the past | Limitation of retrosynchronization | Check the period settings in the app |
Also, the data from the bracelet must first get into the Xiaomi Wear app (when opening or updating the background), and only then the sync will transmit it to Google Fit. This process can take from 1 to 15 minutes depending on the interval settings.
⚠️ Warning: Do not try to use multiple sync apps at the same time (e.g. Health Sync and Syncer) and this will result in conflicting entries in the Google Fit database and duplicate steps.
