Xiaomi Body Composition Scale 2: A Complete Guide to Using Smart Scales

The Xiaomi Mi Body Composition Scale 2 is not just a weight measurement device, but a full body composition analyzer with 13 key indicators: from fat percentage to muscle mass. However, many users face difficulties when first connecting, interpreting data or synchronizing with the application. This article will help you understand all the nuances of working with the device, from unpacking to professional dynamics analysis.

Unlike the classic mechanical scales, the Body Composition Scale 2 uses bioimpedance analysis technology (BIA), It's a device that sends a low electrical current through the body to assess the composition of tissues, and in order to be accurate, it's important not only to adjust the gadget properly, but also to comply with the weighing conditions. We will take a detailed look at each step, from installing batteries to decoding medical terms in the Mi Fit app.

We will focus on common mistakes: why the scales are showing the wrong weight, how to avoid sync failures with the phone, and what to do if the device does not turn on. At the end of this article, you will find answers to frequent questions and tips on extending the life of the scales.

1.Preparation and preparation for the first use

In the Xiaomi Mi Body Composition Scale 2 you will find:

• 📦 The scales themselves (white or black version)
• 🔋 4 AAA batteries (already installed in factory packaging)
• 📄 Short instructions in several languages (including Russian)
• 📱 QR-code for downloading the Mi Fit application

Before first turning on, follow the following steps:

1. Remove the protective film from the display and contact areas (4 metal circles on the surface of the scales).
2. Check if the batteries are installed - to do this, turn the scales and open the compartment (you will need a coin or screwdriver).
3. Put the scales on a flat, hard surface (tile, laminate, wood) and a carpet or soft coating will distort the results.

💡

If the batteries are out, replace them with new ones. AAA strained 1.5V. The use of batteries can lead to failures in the operation of sensors.

Important: The scales automatically turn on when you press the platform with your foot. If the display does not respond, check:

• 🔋 Battery position (observe polarity) + and −).
• 📶 The presence of interference from other wireless devices (routers, microwaves).
• 🌡️ The temperature in the room - the optimal range of 10–40°C.

2. Connect to the Mi Fit application: step-by-step instructions

Without synchronization with Mi Fit, the scales will show only basic data (weight and weight). IMD). To obtain a full analysis of the composition of the body, you need to connect the device to a smartphone.

Download the Mi Fit app:

• 📱 Android (Google Play)
• 🍎 iOS (App Store)

Follow the algorithm further:

Sign up or sign in to your Xiaomi account

Press «+» → «Add the device» → «Libra»

Select the Mi Body Composition Scale 2

Follow the instructions on the screen (turn on Bluetooth)

Stand on the scale for automatic synchronization-->

If the scales are not detectable:

⚠️ Attention: Turn it off VPN and check that your smartphone supports Bluetooth 4.0 or later. iPhone requires iOS 10.0+.

Once successfully connected, the Mi Fit profile will show a "body composition" section with dynamic graphs.

• 📊 Set goals for weight, fat, or muscle.
• 👥 Add profiles for family members (up to 16 users).
• 🔄 Export data to Google Fit or Apple Health.

3. How to weigh properly: 5 rules for accurate data

Bioimpedance technology is sensitive to external factors to minimize error (up to a maximum of two years). ±0.1 kg for weight and ±3% for fat, follow the following conditions:

Critical error: Wet or sweaty feet increase current conductivity, which leads to a decrease in fat percentage by 5-10%. Always wipe your feet before weighing.

For women, additional nuances:

• 🩸 During menstruation, the indicators of water and fat can be overstated by 1-2%.
• 🤰 In pregnancy, bioimpedance analysis is contraindicated (use only the weight measurement regimen).

4. Decoding of indicators: what do the numbers in Mi Fit mean

Xiaomi Body Composition Scale 2 measures 13 parameters.

Weight is a basic indicator in kilograms, displayed on the scale display and in the app.

2. IMD (Body mass index: weight to height (weight/height2), normal: 18.5–24.9.

3. Body Fat is the proportion of adipose tissue, optimal: 18-24% for men, 25-31% for women.

4 Muscle Mass - muscle weight in kg. Important for athletes: the increase in this indicator with a decrease in fat indicates proper training.

Less obvious but useful metrics:

• 💧 Body Water is 50-65% normal, below 50% is a sign of dehydration.
• 🦴 Bone Mass: Skeletal weight, and the decrease may indicate osteoporosis.
• 🧠 Visceral Fat: Fat around organs: Normal: 1-12 (above 13, risk of diabetes).
• ⚡ Main exchange (BMR) — Calories your body spends at rest. Use them to calculate your daily allowance.

Example of interpretation:

⚠️ Attention: If you lose weight, you lose muscle, not fat, and that's a signal to reconsider your diet and add strength training.

💡

To objectively assess the dynamics, compare the performance for the same day of the week (for example, only on Mondays).

Typical problems and their solutions

Even when you set it up properly, users are experiencing errors, and here are the most common ones:

Problem 1: Libras are not included

• 🔋 Check the batteries (replace them with new ones, even if the old ones seem to work»).
• 🔌 Reset the scales: Remove the batteries for 10 seconds, then insert back.
• 📱 Update the firmware through Mi Fit (Section "Device Settings»).

Problem 2: Not synced with the phone

• 📶 Enable Bluetooth and Geodata on your smartphone.
• 🔄 Reboot both devices.
• 🗑️ Remove the scales from Mi Fit and add again.

Problem 3: Shows the wrong weight

• ⚖️ Place the scales on a hard surface (not on a carpet!).
• 🧘 Stand up straight without leaning on the edges.
• 📏 Check your growth settings in your Mi Fit profile (growth error distorts) IMD).

Problem 4: The application does not save data

• 📵 Check your internet connection (data synced to the cloud).
• 🔄 Update Mi Fit to the latest version.
• 📧 Sign in to Xiaomi account (no data is saved without authorization).

💡

If the scales show a Lo error, it means battery grade. Replace them, even if they are "nearly new."

6. Comparison with other Xiaomi models

Xiaomi’s smart scale lineup has several models, and this is what makes the Body Composition Scale 2 different from its peers:

Choose Body Composition Scale 2 if you need it.

• 📈 Maximum analysis of body composition.
• 🔍 High accuracy for sporting purposes.
• 📱 Integration with fitness applications (Apple Health, Google Fit).

7 How to extend the service life of the scales

If used carefully, the scales will last 3-5 years to avoid breakdowns.

Maintenance of the hull:

• 🧼 Wash the surface with a wet (not wet!) cloth.
• 🚫 Do not use abrasive cleaning products.
• 🌡️ Keep it in a dry place (moisture). <80%).

Exploitation:

• 🔋 Change batteries every 6 to 12 months (even if the scales work).
• ⚡ Avoid temperature changes (do not place near the battery or air conditioner).
• 👣 Don’t jump on the scales – it damages the sensors.

Software:

• 🔄 Regularly update the firmware through Mi Fit.
• 📱 Do not delete the Mi Fit app or you will lose your data history.

⚠️ Warning: If the scales fall from a height or have been shed, turn them off immediately and dry for 24 hours (don't turn them on sooner!).
