How to connect Xiaomi floor scales to a smartphone: full instruction 2026

Introduction: Why sync Xiaomi scales to your phone?

Xiaomi’s smart floor scales are not just a weight measurement device; they analyze body composition (fat, muscle, water), keep a history of changes, and help track fitness or diet progress, but all of these features are only available when connected to a smartphone through a special app.

Without synchronization, you'll only get basic data on the scale screen -- weight numbers without detail and dynamic analysis -- but with a phone connection, you'll get more options: change schedules, nutrition tips, integration with other Xiaomi gadgets (like Mi Band bracelets), and even exporting data to Google Fit or Apple Health.

In this article, we will analyze all the ways of connecting (via Mi Fit, Zepp Life and alternative methods), consider typical errors and give tips for setting up for maximum measurement accuracy. The instructions are relevant for Xiaomi Mi Body Composition Scale 2, Xiaomi Smart Scale 2, Xiaomi Body Fat Scale 2 and other smart scales of the brand.

What scales Xiaomi supports phone connection?

Not all Xiaomi floor scales are equipped with Bluetooth for synchronization, here is the current list of models with smartphone connectivity support (2026):

• 🔹 Xiaomi Mi Body Composition Scale 2 is the most popular model with the analysis of 13 body parameters.
• 🔹 Xiaomi Smart Scale 2 – budget option with basic functions (weight, BMI, fat, muscles).
• 🔹 Xiaomi Body Fat Scale 2 – improved version with increased measurement accuracy.
• 🔹 Xiaomi Mi Scale (first generation) – outdated model, but still found on sale.
• 🔹 Xiaomi Mi Body Composition Scale (without the number "2") - the predecessor of the second version.

How to check for Bluetooth support? The Bluetooth 4.0/5.0 or Low Energy (BLE) protocol should be listed on the box or in the model specifications. If the scales are battery-only and don’t have a synchronization button (usually hidden under the lid), it’s likely a mechanical model with no smart functions.

Preparing for the connection: what to do in advance

Before syncing the scales with your phone, follow a few mandatory steps that will save time and avoid the typical mistakes:

1. Recharge or replace batteries. Xiaomi scales run on 4 AAA batteries. If the display on the screen flashes or shows low charge, replace the batteries. Use high-quality alkaline batteries (for example, Duracell or Energizer) - cheap can quickly discharge.
2. Install the application. Download the official software: 📱 For Android: Mi Fit or Zepp Life (new name for international version). 🍎 For iOS: Mi Fit.

Step-by-step: how to connect Xiaomi scales to the phone

Consider the synchronization process using the Mi Fit app (the steps are similar for Zepp Life, but with a different interface).

Step 1: Launching the application and adding the device

Open Mi Fit and go to Profile → Add Device. From the list, select Libra (or Mi Body Composition Scale 2 if your model is automatically determined).

Step 2: Activation of the balance pairing mode

Stand on the scale with bare feet (socks or slippers distort readings), your weight will appear on the screen, followed by a Bluetooth icon (📶) — This means that the scale is ready to plug in. If the indicator does not appear, press the sync button (usually hidden under the lid, next to the battery compartment).

Step 3: Confirmation of connection in the application

On the phone will be a request to pair with the device of the form MI_SCALE_XXXX. Confirm the connection. The app may ask to allow notifications -- agree to receive weigh-in reminders.

Step 4: Entering personal data

For an accurate analysis of the body composition, specify in the profile:

• 👤 Gender (male/female).
• 📏 Growth (in centimeters).
• 🎂 Age.
• 🏃‍♂️ Activity level (sedentary lifestyle, moderate loads, intense training).

These data affect the calculation of the percentage of fat, muscle and calorie norms.

Step 5: Test weighing

Stand on the scale again. In 5-10 seconds, the data will automatically be transmitted to the application. If the synchronization does not occur, check:

• 🔋 Battery charge.
• 📶 Distance to the phone (no more than 5 meters).
• 🚫 No interference (other Bluetooth devices, microwaves, Wi-Fi routers at 2.4 GHz frequency).

💡

If the scales don't plug in, reboot the phone and scales (remove the batteries for 30 seconds), which solves the problem 80 percent of the time.

Table: comparison of Mi Fit and Zepp Life apps for Xiaomi scales

Since 2022, Xiaomi has been gradually moving users from Mi Fit to Zepp Life. What is the difference and which app is better to choose?

Bottom Line: Zepp Life offers deeper analytics and convenient reminders, but requires additional sync tweaking with other services.Mi Fit is easier to use, but more functional for basic tracking.

💡

For maximum accuracy, weigh at the same time (preferably on an empty stomach in the morning) and in the same clothes (or without it).
