How to connect Xiaomi scales to Samsung phone: full instructions

Integrating smart tech into everyday life has become a standard for many users of the Xiaomi ecosystem.Small health gadgets such as smart scales that track not only body weight, but also percentage of fat, muscle mass and water are especially popular.However, Samsung smartphone owners often face nuances when initially setting up these devices due to the features of the One UI shell and the aggressive energy saving policy of Android.

The synchronization process can seem confusing to a beginner, especially when an app doesn’t see a device or refuses to transfer data. In this article, we’ll take a look at each connection step, paying special attention to the specific security settings of the Samsung Galaxy, which often block the operation of Bluetooth background services. You’ll learn how to properly prepare the gadget, which application to choose and what to do if the standard algorithm fails.

The right setup from the first time will ensure stable statistics collection and allow you to fully unleash the potential of your fitness tracker in conjunction with weights. We will consider working with the official utilities Mi Fit (now Zepp Life) and Mi Home, as the choice of platform depends on the specific model of your weighing device.

Preparation of equipment and selection of applications

Before you start the pairing procedure, you need to make sure that all the components of the system are ready to work. First of all, check the battery charge on the scales themselves: even if they are new, long-term storage could discharge the batteries. Most models of Xiaomi Mi Body Composition Scale require four AAA batteries, and their quality directly affects the power of the Bluetooth signal.

The second critical step is installing the right software on a Samsung smartphone, and there is confusion between the apps as Xiaomi has changed support platforms. For classic scales (YUNMAI models or older Mi Scale 1/2 versions), Mi Fit, which was renamed Zepp Life, has long been considered the main application.

• 📱 Zepp Life is the main app for most fitness devices in the ecosystem, including second-generation scales.
• 🏠 Mi Home is a universal smart home platform that supports new scale models with scenario integration.
• ⚖️ Mi Fitness is a new app that is gradually replacing Zepp Life for some regions and devices.
• 📶 Bluetooth – Make sure the wireless module is activated in the phone settings.

Download programs should be exclusively from the official Google Play Store or Galaxy Store to avoid malicious code. After installation, do not rush to start pairing, you first need to log in to the application by creating a Xiaomi account or logging in through an existing Google or Facebook profile.

⚠️ Note: Do not attempt pairing of scales via the standard Bluetooth menu in Android settings. Xiaomi smart scales do not appear in the list of available devices to connect directly, as they use a special data transfer protocol managed only through the application.

Step-by-step connection instructions via Zepp Life

The most common scenario is to use the Zepp Life app for Mi Body Composition Scale 2. Launch the app on your Samsung and go to the user profile. In the upper right corner of the screen is the menu icon where you need to select Add device. The system will suggest scanning. QR-code or select a device from a list.

Select Libra and find your model in the list, and then the app goes into search mode, at which point you need to stand on the scale with one foot to activate the screen and start pairing mode, and the indicator on the scale should start flashing, signaling readiness for data transfer via Bluetooth Low Energy.

Once the device name appears on the smartphone screen, click on it to confirm. The communication process takes a few seconds. It is important to hold the phone as close to the weights as possible at this point, ideally putting it next to the floor. Once the connection is successful, the application will request permission to access geolocation and notifications.

Once you're first connected, the scales are automatically calibrated, and you're asked to enter anthropometric data like height, age and gender, which are critical to body composition algorithms, because without them, the scales will only show mass, but they won't be able to calculate the percentage of fat or muscle.

Setting up access rights in Samsung One UI

Samsung smartphones are known for their advanced security system, which sometimes unnecessarily aggressively restricts the background of applications. To stable the scales Xiaomi needs to give the application Zepp Life or Mi Home extended access rights. Without this scale may not sync if the application is folded.

Go to Settings → Apps, find your weights app, and open the Permissions section, where you need to activate location access (for Bluetooth scanners), notifications, and, if available, access to physical activity. In newer versions of Android, Bluetooth access is also made available in a separate resolution.

Next, remove the app from battery optimization. Go to Settings → Device Care → Battery → Background Restrictions. Go to Zepp Life or Mi Home and select Do Not Limit. This will prevent Samsung from forcing the sync service to stop.

⚠️ Note: If you use the Power Saving Mode feature on your Samsung phone, it can block the scales even if there are exceptions. To ensure data synchronization at the time of weighing, it is better to turn off this mode or add the application to the list of exceptions to the energy saving mode itself.

Solving Connection and Synchronization Problems

Despite the simplicity of the procedure, users often encounter errors. One of the most common problems is that the scales show weight, but the data is not transmitted to the phone. This indicates a disconnection between the application and the cloud or a failure in the local Bluetooth connection. Try to completely close the application through the menu of running tasks and open it again.

If the scales are no longer determined by the phone, perform a full reset of the network settings on your smartphone or just turn off and turn on Bluetooth. Sometimes it helps to remove the device from the list of paired in the Bluetooth menu (if it appears there) and re-search through the application. Make sure that the distance between the phone and the scales does not exceed 1-2 meters during settings.

• 🔄 Reboot is a banal but effective way: reboot your Samsung smartphone completely.
• 🔋 Batteries – Replace batteries even if they seem new; cheap batteries may not give you the voltage you need.
• 📲 App cache – clear the app’s cache in Android settings without deleting user data.
• 🌐 Internet – Check for Wi-Fi or mobile network connectivity stability, as primary authorization requires online.

In rare cases, the problem lies in the incompatibility of software versions. Make sure that the Galaxy Store or Play Market store does not have updates for the application itself or Bluetooth system components. It is also useful for Samsung to check for updates through the Galaxy Store in the Update Everything section, since system drivers are updated regardless of the major Android updates.

💡

Useful tip: If the scales are "hanging" and show zeros or flashing without stopping, remove the batteries, wait 30 seconds, insert back and immediately stand on them with two legs for calibration. This will force the controller to restart.

Integration with Samsung Health and Google Fit

One of the main goals of buying smart scales is centralizing health data: Samsung owners typically use the native Samsung Health app, so it's important to set up a link between the Xiaomi and Samsung ecosystem.Unfortunately, there's no direct integration between Zepp Life and Samsung Health, but there are proven workarounds.

The most reliable way is to use an intermediate link in the form of Google Fit. In the settings of the Zepp Life application, find the Add Accounts section and link Google Fit. After that, all data about weight and body composition will automatically fly to Google services. Then in the Samsung Health settings, you need to allow data import from Google Fit.

Alternatively, third-party synchronization apps like Health Sync (available on the Play Store) allow you to directly transfer data from Zepp Life to Samsung Health with flexible prioritization, which is especially useful if you want to see all the statistics in one interface without manual input.

💡

Synchronization Chain: Xiaomi Libra → Zepp Life → Google Fit → Samsung Health. It is the only stable way to combine data into one ecosystem.

Measurement accuracy and calibration

Smart scales use bioimpedance analysis (BIA) to send a weak, imperceptible electric current through the body. Tissue resistance can calculate the percentage of fat, muscle and water. However, this method is sensitive to external conditions. To get accurate data, the scale must stand on a completely solid, flat surface (tile, laminate), but not on the carpet.

Time of day also plays a role. Weighing yourself on an empty stomach in the morning, after going to the toilet and before drinking water is recommended. At this time, the body is in the most stable state, and the indicators will be comparable to day-to-day. Evening measurements can show a difference of up to 1-2 kg due to swelling and food, which is the norm of physiology, not a mistake in weights.

If you notice a sharp jump in the percentage of fat at a stable weight, check the moisture of the feet. Dry skin of the feet has more resistance, which can distort the calculations. In such cases, Xiaomi algorithms can give an error. Wipe the contacts on the scales and feet with a wet (not wet) wipe before measuring.
