How to see the fat content on the scales Xiaomi: analysis of all ways

Xiaomi’s smart scales are not just a weight measurement device, they’re full body composition analyzers that can show fat percentage, muscle mass, water level, and even bone density. However, many users are faced with the problem of where to look at this data and how to interpret it correctly. Especially often, questions arise for beginners who have just unpacked the Mi Smart Scale 2 or Xiaomi Body Composition Scale 3 and do not understand why the scale screen displays only weight and the rest of the metrics are “hidden”.

In this article, we’ll look at all the ways Xiaomi’s scales can view fat, from basic display on the screen to detailed analysis in the Mi Fit app (or Zepp Life for new models), how to synchronize data, which models support advanced analytics, and what to do if the scales don’t see your fat, and why the numbers may differ from lab tests and how to achieve maximum accuracy.

If you've already tried to find fat percentages on your scales and you haven't found anything, don't be quick to blame the technique. 90% of the time, the problem is with the wrong profile settings or the lack of sync with your phone. Next, you'll find step-by-step instructions for each situation, including hidden features that aren't written about in the official manuals.

1.What scales Xiaomi shows percentage of fat?

Not all Xiaomi smart scales are able to analyze body composition. Basic models (for example, Mi Smart Scale 1) measure only weight, but more advanced versions are equipped with a bioimpedance sensor that passes a weak electric current through the body and calculates the percentage of fat, muscle and water.

Here is a full list of models with support for body composition analysis (current for 2026):

• 🔹 Xiaomi Mi Smart Scale 2 – the first mass-produced model with bioimpedance, shows 13 metrics (including visceral fat).
• 🔹 Xiaomi Body Composition Scale 2 – improved version with more accurate sensor and support for Apple Health.
• 🔹 Xiaomi Smart Scale 3 - budget version with simplified analysis (9 metrics).

How do you know if your model supports fat analysis?

• 🔍 Go to the Mi Fit app → Profile → Devices → [Your scales. If you have a "body composition analysis" in the description, it means that the function is.

⚠️ Note: If your model doesn't support bioimpedance, no "secret" button combinations or firmware updates will add this feature.

2. Where to watch the percentage of fat: on the scale screen or in the application?

The way the data is displayed depends on the scale model and its settings. Most devices only show the weight on the screen, and the rest of the metrics (including fat) are transmitted to the application. However, some advanced models (for example, Body Composition Scale 2) can display 2-3 key metrics directly to the display.

How to check what is displayed on the screen:

If the display is only weighted, don't worry: full data is always available in the app.

1. Open Mi Fit (or Zepp Life for new models)
2. Go to the Profile tab → Devices → [Your scales].
3. Choose the last dimension, and you'll have detailed statistics, including fat percentage.

💡

If the scales aren't synced with your phone, try reconnecting them in Bluetooth settings. Sometimes it helps to reboot your smartphone.

Table: What different models show on the screen

Important: The accuracy of the indicators is influenced by skin moisture, time of day and even the phase of the menstrual cycle (in women). For an objective assessment, weigh yourself on an empty stomach in the morning, after using the toilet.

3. Step-by-step instruction: how to see fat in the Mi Fit app

If your scales are synced to Mi Fit but you don’t know where to look for fat data, follow this instruction:

Weigh yourself on the scales (required to be bare feet)|

Open the Mi Fit app on your phone|

Go to the Profile tab (the icon of the person at the bottom)|

Select "Devices" → [Your scales]|

Click on the last dimension → section “Composition of the body"-->

Detailed analysis:

1. Weighing. Stand on the scale and wait for the signal (usually a beep or vibration) Do not move during the measurement.
2. Synchronization: The data will automatically be transmitted to Mi Fit if the scale is connected to the phone via Bluetooth: 📱 Is Bluetooth on the phone. 🔋 Charge of scales (if discharged, they will not transmit data). 🔄 Update the Mi Fit app to the latest version.

Data review.

Profile → Devices → [Your scales] → History of measurement

You'll see in the report:

• 🍗 Fat percentage (norm: 18–24% for men, 25–31% for women).
• 💪 Muscle mass (shows how many pounds of weight you have in your muscles).
• 💧 Water level (optimum 50–60%).
• 🦴 Bone mass (important for assessing skeletal health).

⚠️ Note: If the report does not contain fat, check if your gender, age and height are correctly listed in the Mi Fit profile!

4.How to set up the display of fat on the scale screen (if supported)

If your scale model can show the percentage of fat on the display (for example, Body Composition Scale 2), but by default does not, you can change the display settings.

Method 1: Through the Mi Fit application

Method 2: Through a button combination (for some models)

On the scales Mi Smart Scale 2 and Body Composition Scale 2, you can manually switch the metrics on the screen:

1. Stand on the scale and wait for measurements.
2. Then, you can easily click on the scales (not go down!) and flip through the metrics: weight. → fat → muscle → water.
3. To fix the desired metric (for example, fat) as the main one, hold the press for 3 seconds.

Method 3: Resetting screen settings

If the scales “forgot” to show fat, try resetting their settings:

1. Turn off the scales (press the button for 5 seconds).
2. Turn them back on by holding the 10 seconds button – this will reset the screen settings.
3. Re-synchronize with Mi Fit.

💡

If after all the manipulations, the fat on the screen never appeared, check if this feature is disabled in regional settings. Some models (for example, for the Chinese market) have restrictions on displaying medical metrics.

5.Why does Xiaomi scale show an inaccurate percentage of fat?

Many users complain that Xiaomi’s weight fat scores are very different from lab tests (like a bioimpedance test at a clinic), which is normal – the margin of error of home weights is 3-5%, and it is influenced by dozens of factors.

The main reasons for inaccuracy:

• 🕒 Time of day: Fat percentage is higher in the morning (due to dehydration), in the evening - lower.
• 🚰 Hydration level: If you drink a liter of water before weighing, your fat will decrease by 1-2%.
• 🍗 After eating, scales may show an inflated percentage of fat due to changes in electrical conductivity of tissues.
• 🏋️ Physical activity: After exercise, muscles accumulate water, which distorts the results.
• 🩺 Medical factors: Swelling, menstruation, diuretics affect bioimpedance.

How do you minimize the error?

1. Weigh yourself at the same time (optimally, in the morning after the toilet).
2. Do not drink or eat 2 hours before the measurement.
3. Use the scales with bare feet (socks distort the current).
4. Before weighing, wash and wipe your feet - sweat or cream reduces accuracy.
5. For objective dynamics, follow the trend, not one-time indicators.

⚠️ Note: If the scale shows a percentage of fat below 5% or above 40%, it is a clear mistake.

💡

To check the accuracy of the weights, compare them with the data of a professional body composition analyzer (for example, in a fitness club), a difference of 3-4% is considered normal.

6. Alternative ways to view data (if Mi Fit does not work)

If the Mi Fit app is buggy or you prefer other services, there are a few alternative ways to get Xiaomi scale data:

Method 1: Sync with Google Fit or Apple Health

• 📱 In Mi Fit go to Profile → Settings → Synchronization of data.
• 🔗 Connect to Google Fit or Apple Health.
• 📊 Data on fat will now be duplicated in these applications.

Method 2: Exporting data to CSV

To analyze the dynamics, you can unload the history of measurements:

1. In Mi Fit, click on the weight chart.
2. Select Data Export (the gear icon in the upper right corner).
3. Send the file to your mail and open it in Excel.

Method 3: Third-party applications

Some apps (such as Health Sync or SyncSolver) can pull data from Mi Fit and visualize it differently, but beware: such programs may violate Xiaomi’s privacy policy.

Method 4: Web version of Mi Fit

Go to the site. https://account.huami.com, log in and go to Devices, and there's a history of measurements, including fat percentage.

7. Frequent errors and how to fix them

If Xiaomi scales don’t show fat percentage or give out clearly incorrect data, check these points:

Mistake 1: Libras are not synchronized with the phone

• 📱 Make sure your phone is Bluetooth enabled and geolocation permission enabled (required for Mi Fit to work).
• 🔄 Reboot phone and scales.
• 🔌 Check the batteries in the scales (if discharged, synchronization does not work).

Mistake 2: Fat data is not stored

• 📝 Check if your height, weight and age are correctly listed in your Mi Fit profile.
• 🔄 Update the firmware of the scales through the app.
• 📲 Remove the scales from the list of devices and connect again.

Mistake 3: Libra shows an error of "Err" or "Lo"

• 🔋 «Lo means low battery charge – replace the batteries.
• 🧘 «Err can occur if you move while weighing or stand on a scale in shoes.
• 🔄 If the error repeats, reset the scales to factory settings.

Mistake 4: Fat percentage doesn’t change despite diet

• 📅 Bioimpedance analysis responds to changes with a delay of 2-3 weeks.
• 💧 You may be losing water, not fat (check your hydration level in the report).
• 🏋️ If you build muscle, weight can stand still, and the percentage of fat - decrease.

💡

If none of these methods worked, contact Xiaomi via the Mi Fit app (Feedback section). Provide a scale model and a description of the problem, and help diagnose the malfunction.
