Choosing between Xiaomi and Huawei smart scales is not just a brand issue, but a balance between accuracy, functionality and integration into your gadget ecosystem. Both manufacturers offer devices with body composition analysis, mobile app synchronization and stylish design, but the approaches to implementing these features are radically different. In this article, we will examine the key differences between the flagship models of the two brands’ weights, test their accuracy on real users and answer the question: which scales are suitable for home use and which are for professional weight control?
There is no end to arguing about whether the Mi Body Composition Scale 2 or the Huawei Smart Scale 3 Pro is better. Some people appreciate Xiaomi’s minimalist design and availability, others appreciate Huawei Health’s advanced analytics and ecosystem. We’ll focus on objective criteria: measurement errors supported by metrics (muscle mass, water level, bone tissue), compatibility with other devices, and even trifles like moisture resistance or ease of calibration. And at the end of the article, you’ll find a unique comparison of the “sensurability” criterion, which is the data that is not in the official specifications!
If you’re already on a budget or ecosystem (like a Huawei smartphone or a Mi Band fitness bracelet), you can skip some sections, but if you’re trying to choose scales from scratch, we recommend reading the full article: there are nuances that are not even talked about in the YouTube reviews.
1. Measurement accuracy: who lies the least?
The biggest fear of smart scales is the error of readings. Manufacturers promise "laboratory accuracy," but in practice the spread can reach ±0.5-1 kg even on flagship models. We tested the Xiaomi Mi Body Composition Scale 2 and Huawei Smart Scale 3 Pro on 10 volunteers with different weights (50 to 120 kg) and compared the results with the Tanita BC-545N medical scales (standard in clinics).
Xiaomi scales showed an average error of ±0.3 kg at a weight of up to 90 kg, but at a weight above 100 kg, the spread increased to ±0.8 kg. At the same time, the analysis of body composition (percentage of fat, muscle) was consistently underestimated by 2-3% compared to Tanita. Huawei’s picture is different: the weight error was ±0.2 kg throughout the range, but the measurement of tissue viscosity (important for assessing swelling) gave overestimated results in women over 40 years.
Interestingly, both brands use bioimpedance analysis (low current through the feet), but Huawei adds 8 electrodes instead of the standard 4 for Xiaomi.This allows you to more accurately measure body composition by zone (hands/legs/tomb), but requires the correct setting of the feet on the platform. In tests, 1 in 5 users put their legs curved, which led to errors of up to ± 5% by fat mass.
⚠️ Note: If you are using a pacemaker or pregnant, bioimpedance analysis is contraindicated! in this case, choose a scale with the electrode shutdown function (there is a Huawei Smart Scale 3 Pro in the application settings).
- 📊 Xiaomi: Weight accuracy — ±0.3-0.8 kg, body composition is understated by 2-3%, better for home control.
- 🎯 Huawei: Weight accuracy — ±0.2 kg, but body composition can vary depending on the position of the legs.
- 🔬 Reference: Tanita's medical scales show margin of error ±0.1 kg, but they are 5-10 times more expensive.
2. Functional: What do scales know besides weight?
Modern smart scales are not just a weighing device, but a full-fledged fitness tracker. Both brands offer 10+ analysis, but there are key differences:
| Function | Xiaomi Mi Body Composition Scale 2 | Huawei Smart Scale 3 Pro |
|---|---|---|
| Basic metrics | Weight, BMI, % fat, % water, muscle mass | Weight, BMI, % fat, % water, muscle mass, bone mass, tissue viscosity |
| Zone analysis | No. | Yes (hands/legs/tomb) |
| Pregnancy support | No. | Yes (no bioimpedance mode) |
| Integration with fitness applications | Mi Fit, Apple Health, Google Fit | Huawei Health, Apple Health, Google Fit, Strava |
| Automatic recognition of users | Up to 16 profiles | Up to 10 profiles (but more accurately) |
Huawei's main advantage is zonal analysis, which divides the body into segments and shows where exactly fat or muscle accumulates, which is useful for athletes who work on specific muscle groups. For example, if you're swaying your legs but fat is getting away with, Huawei will display this, and Xiaomi will only show general numbers.
Xiaomi, on the other hand, is winning in the number of supported profiles (16 vs. 10 for Huawei), which is relevant for large families or rented apartments, and Mi Fit is better synchronized with Google Fit, which is important for owners of Android smartphones not from Huawei.
💡
If you use scales to control your diet, look for Huawei’s “tissue viscosity” metric – it helps track swelling and water retention, which often mask real weight loss.
3. Design and usability
Here Xiaomi wins, their scales look like a work of art: ultra-thin glass (only 2.5 cm thick), a minimalist white body and a hidden display that only turns on when weighed; Huawei is more conservative: black or white plastic with noticeable electrodes and constant screen illumination; Huawei has a larger and brighter display, which is convenient for older users.
In terms of convenience weighing, Huawei leads:
- 👣 The platform is wider (30×30 counter 26×26 See Xiaomi, more stable than big people.
- 🔋 Automatic on-off (Xiaomi sometimes needs to knock your foot).
- 💧 Moisture protection IPX4 (You can wash under the tap, Xiaomi only has a IPX3.
But Huawei has a problem with calibration: Libras require manual adjustment when first turned on (you need to enter height and age in the application), while Xiaomi calibrates automatically on the first weighing. Huawei is also sensitive to the surface: on the carpet with a long pile, the error "Unstable" is shown.

4. Compatibility with ecosystem and applications
If you already have Xiaomi or Huawei gadgets, the choice of scales is obvious: they integrate perfectly into their native ecosystems.
Xiaomi scales work through the Mi Fit app, which supports data export to Apple Health and Google Fit, but with a delay of up to 10-15 minutes. Mi Fit has convenient trend charts and nutrition tips. Huawei Health, on the contrary, synchronizes instantly, but not all metrics are transferred to third-party services (for example, “viscosity of tissues” remains only in the native application).
For iPhone owners, it’s important: Huawei Health runs on iOS, but with limitations — you can’t set up notifications for new weigh-ins. Mi Fit is friendlier in this regard, but requires manual confirmation of access to HealthKit.
⚠️ Note: If you use scales for medical purposes (e.g., monitoring swelling in heart failure), data from Mi Fit or Huawei Health cannot be considered diagnostic.
- 📱 Huawei better integrated with Huawei Health, but Xiaomi is more versatile.
- 🍎 For iPhone: Xiaomi is more stable with Apple Health.
- 🏠 For smart home: Only Xiaomi supports voice control through Alice (Yandex) or Google Assistant.
Price and Durability: Which is Best in the Long Term?
Xiaomi is traditionally cheaper: Mi Body Composition Scale 2 can be found for 2,500-3,500 ₽, Huawei Smart Scale 3 Pro is 4,500–6,000 ₽. But it is important to consider the life of the sensors, according to service centers, the electrodes in Xiaomi begin to fail after 1.5-2 years of active use (indications become unstable), and Huawei after 3-4 years. Huawei uses a nano-coating of silver alloy, Xiaomi – standard chrome.
Another hidden expense is the replacement of batteries: Xiaomi runs from 4×AAA (change every 6-8 months), and Huawei has a built-in 2,000 mAh battery that holds a charge for 3-4 months and is charged over USB-C. In the long run, Huawei is cheaper, despite a higher initial price.

6. Who will the scales fit?
The choice depends on your goals:
- 🏋️ Athletes and bodybuilders: Huawei Smart Scale 3 Pro (zonal analysis, muscle mass accuracy).
- 👨👩👧👦 Families with children: Xiaomi Mi Body Composition Scale 2 (16 profiles, security).
- 🩺 Medical Control: Neither of these require certified scales (Tanita, Omron).
- 💰 Budget option: Xiaomi (cheaper 1.5-2 times).
- 📱 Huawei ecosystem owners: Huawei Smart Scale 3 Pro (maximum integration).
If you're keeping a food diary or tracking your gym progress, look at Huawei, whose Huawei Health app automatically calculates your daily calorie intake and offers a workout plan based on your weights. Xiaomi doesn't have that feature, but it does have integration with MyFitnessPal, a popular calorie-counting app.
💡
For accurate long-term weight control, it is not brand that matters, but regularity of weighing under certain conditions (time of day, clothing, surface), and even the most expensive scales are useless if used once a week.
