Xiaomi Mi scales: what are the models and how to choose the right ones?

Xiaomi Mi smart scales are no longer just a weight measurement device. Today, they are full-fledged fitness trackers that can analyze body composition, sync with mobile applications and even integrate into the smart home ecosystem. But a variety of models — from the budget Mi Body Composition Scale to the premium Mi Smart Scale 3 — often confuses customers: which scales to choose, what they differ from and what to look for when buying?

In this article, we will analyze all the current Xiaomi Mi scale models, compare them by key parameters: measurement accuracy, functionality, compatibility with applications and design. You will learn which scales are suitable for basic weight control and which can replace a professional body composition analyzer. We will also reveal the hidden nuances of working with Xiaomi scales, which the manufacturer does not say about – for example, why the readings may differ from mechanical scales and how to calibrate the device correctly.

1. Overview of all Xiaomi Mi weight models: from budget to premium

Xiaomi’s smart scale range includes more than 10 models, but only 5-6 current devices are actively represented on the market.

• 📏 Basic scales measure only weight (sometimes BMI). Examples: Mi Smart Scale Lite, Mi Body Composition Scale V1.
• 🧬 Body composition analyzers -- measure percentage of fat, muscle, water, bone mass, and other metrics, examples: Mi Smart Scale 2, Mi Body Composition Scale 2.

It's important to understand that even within the same group, devices can be very different, for example, the Mi Smart Scale 2 and the Mi Body Composition Scale 2 are almost identical in appearance, but they use different analysis algorithms and sensors.

2. Xiaomi Mi Smart Scale 2: Best Price and Functional Balance

Xiaomi Mi Smart Scale 2 is the most popular model among users due to the optimal price-to-opportunity ratio. These scales support 13 body analysis metrics, including:

• 📊 Weight (up to 50 g)
• 💧 Percentage of water in the body
• 🏋️ Muscle mass
• 🦴 Bone mass
• 🔥 Basic metabolism (BMR)

The model features support for up to 16 users (in the Mi Fit or Zepp Life app), which automatically recognizes the user by weight and saves the measurement history, the body is made of tempered glass 6 mm thick, and the sensors are coated with gold to improve accuracy.

⚠️ Attention: The Mi Smart Scale 2 scales require mandatory calibration when first turned on. If you skip this step, the readings can vary by ±0.3-0.5 kg. Calibration takes 2-3 minutes and is performed through the application.

Among the disadvantages, users note:

• ❌ No support for Apple Health (Mi Fit and Google Fit only).
• ❌ The battery (4×AAA) is discharged in 4-6 months when used actively.
• ❌ Incorrectly working on carpeting (needs a hard surface).

💡

To extend the life of the batteries, turn off the scales after using the button on the back. In standby mode, they consume energy to maintain communication with Bluetooth.

3. Xiaomi Mi Body Composition Scale 2: Professional Analysis for Reasonable Money

The Mi Body Composition Scale 2 is an updated version of the previous model with improved sensors and enhanced functionality.

• 🔍 More accurate analysis of body composition thanks to 4 electrodes (instead of 2 in the base model).
• 📱 Support for Zepp Life with advanced analytics (e.g. weekly dynamics charts).

The scales support 17 metrics, including unique indicators:

• 🧠 Visceral fat (dangerous fat around internal organs)
• 👶 Metabolic Age (Metabolic Age – comparing your metabolism to your average age).
• 🏃 Body Score (integral fitness score from 1 to 100).

Among the shortcomings:

• ⚠️ Higher price (30-40% more expensive than the Mi Smart Scale 2).
• ⚠️ Requires a firmware update at the first connection (otherwise synchronization errors are possible).

4. Xiaomi Mi Smart Scale 3: flagship with support for Wi-Fi and voice control

The Mi Smart Scale 3 is the top model in the lineup that stands out:

• 📶 Wi-Fi support (besides Bluetooth), which allows you to synchronize data without a smartphone.
• 🗣️ Voice control via Alice or Google Assistant (e.g., "OK Google, show me my weight").
• 📈 19 metrics, including unique: Protein mass (important for athletes) Stress level (assessed by heart rate and heart rate variability).

The scale body is made of matte glass with anti-slip coating, and the sensors are protected from moisture according to IP54 standard. The complete package comes with a wireless charging pad (scales support Qi technology).

⚠️ Warning: Voice control only works when connected to a Xiaomi router (e.g. Mi Router 4A). Other routers may have synchronization issues.

Of the minuses:

• ❌ High price (from 4,500 ₽).
• ❌ Large size (30×30 cm) is inconvenient for small bathrooms.
• ❌ Some metrics (e.g., "stress level") require additional manual calibration.

5.Budget models: Mi Smart Scale Lite and Mi Body Composition Scale V1

If you don’t need advanced features, you can save money and choose one of the budget models:

Xiaomi Mi Smart Scale Lite is the simplest scale in the lineup. They measure only weight (with an accuracy of ± 100 g) and calculate BMI. Suitable for those who want to just control body weight without unnecessary metrics. The body is plastic, without backlighting. They are powered by 3 AAA batteries (sufficient for 12-18 months).

The Xiaomi Mi Body Composition Scale V1 is the first version of the body composition analyzer, which is inferior to modern models in accuracy (accuracy up to ±100 g versus ±50 g for new weights), but still in demand due to the low price (1800 ₽) Supports 10 metrics, including percentage of fat and muscle mass, the main drawback is the lack of support for new versions of the Mi Fit (requires an old version of the application).

6.How to choose Xiaomi Mi scales: a step-by-step guide

To avoid making a mistake, answer 5 key questions:

1. What metrics do you need? ✅ Weight Only → Mi Smart Scale Lite. ✅ Weight + Basic Analysis (fat, muscle) → Mi Smart Scale 2. ✅ Complete analysis (visceral fat, metabolic age) → Mi Body Composition Scale 2 or Mi Smart Scale 3.

Also note:

• 🔋 Type of power: Batteries are cheaper to replace, but the battery is more convenient.
• 📏 Platform size: If you have a large foot (footwear size >44), choose models with an area ≥28×28 see WEB
• 🛁 Moisture protection: For the bathroom, it is better to take scales with IP54 or higher.

💡

If you are an athlete or dieter, the priority is accuracy in measuring fat and muscle mass, in which case it is better to overpay for the Mi Body Composition Scale 2 or Mi Smart Scale 3, since budget models often understate the percentage of fat by 2-3%.

7. Frequent problems and how to solve them

Even the most reliable Xiaomi scales can fail, and here are the most common problems and solutions:

Problem 1: Libras are not switched on or synchronized.

• 🔋 Check the batteries (even if they are new, the contacts may have oxidized).
• 📱 Reinstall the Mi Fit or Zepp Life app.
• 🔄 Reset the scales to factory settings (hold the 10 seconds switch).

Problem 2: The readings are very different from mechanical scales.

• ⚖️ Make sure the scales are on a flat, hard surface (not on the carpet!).
• 🧘 Calibrate through the application (Settings → Calibration).
• 👟 Weigh yourself at the same time (in the morning on an empty stomach) – weight can fluctuate by 1-2 kg during the day.

Problem 3: Libras show a “Lo” or “Err” error.

• 🔋 This means discharged batteries (even if they are new, check for polarity).
• 🧲 It is possible that the scales are near the source of interference (microwave, router).
• 🛠️ If the error repeats, contact the service (possibly damaged sensor).

💡

If the scales show an unrealistically low percentage of fat (e.g., 5% in a person with a visible belly), chances are you have mis-entered height or gender in your profile.

8. Comparison with peers: why Xiaomi and not other brands?

In the smart scale market, Xiaomi competes with Huawei, Honor, Withings and Garmin, which is why many people choose Mi scales:

The main advantages of Xiaomi:

• 💡 The best price/quality ratio is 2-3 times cheaper than Withings with comparable accuracy.
• 🔄 Regular firmware updates (unlike many budget brands).
• 🛒 A wide range of models – you can choose a model for any needs.

But there are also disadvantages:

• ❌ Closed ecosystem – it’s hard to export data to third-party applications (other than Google Fit).
• ❌ Inaccuracies at weight >120 kg (in budget models)
