Xiaomi Mijia Body Scale 2 has 600,000+ reviews on JD.com with a 4.5/5 rating at ¥79 ($11). Users appreciate the sleek minimalist design, automatic user recognition for up to 16 family members, and the seamless Bluetooth sync with the Mi Fit / Zepp Life app. The main complaints are the lack of body fat measurement on this base model and the scale occasionally not auto-waking on the first step. Conclusion: ✅ Worth Buying — the best basic smart scale under ¥100 with proven reliability.

Introduction

The Xiaomi Mijia Body Scale 2 is the best-selling smart scale on JD.com by a wide margin. With 600,000+ reviews and a 4.5/5 rating, it’s one of the most popular Xiaomi products overall. The formula is simple: a high-quality weight scale with smartphone connectivity at a price lower than most analog scales.

At just ¥79 ($11), it costs less than a single meal out. The question isn’t whether it’s worth the money — it’s whether you need the extra features of the more expensive Body Fat Scale version.

Design and Build Quality

The Body Scale 2 is almost invisible in a room — a pure white square of tempered glass with rounded corners. The LED display is hidden under the glass surface when not in use, making it a clean aesthetic piece. The surface is slightly textured ITO coating for the electrodes (on the body fat version) — the base model has no electrodes.

The four rubber feet provide stable footing on tile or hardwood floors. The scale is slim at 25mm thick, making it easy to store vertically if needed. The battery compartment uses 4 AAA batteries with an estimated 12-month battery life.

“After 2 years, the scale still works perfectly. The white glass surface shows no scratches or yellowing. The Bluetooth sync is reliable — I step on it in the morning and my weight appears in Zepp Life automatically. For ¥79, I don’t know what more you could want from a weight scale. It measures weight accurately and looks good doing it.” — JD.com user, verified purchase

Performance

The scale uses four G-shaped sensors with a claimed accuracy of 50g. In practice, measurements are consistent within 100-200g when taken at the same time of day. The auto-recognition feature identifies up to 16 users based on weight pattern — works well for distinct weights but can confuse users with similar body mass.

Bluetooth sync with the Zepp Life app is seamless. Step on, wait for the LED to show your weight, step off, and the data appears in the app within seconds. The app shows trends over time with weekly, monthly, and yearly views.

One minor complaint: the scale occasionally doesn’t auto-wake on the first step. Stepping off and stepping on again always works.

“I use this with the Zepp Life app and it works perfectly. I weigh myself every morning and the app shows a 3-month trend graph. The user recognition correctly identifies me (78kg) vs my wife (54kg) every time. The scale is accurate — I tested it against my gym’s calibrated medical scale and it was within 100g.” — JD.com user

User Reviews by Theme

Accuracy and Consistency

“I tested the scale against my doctor’s medical scale. Over 10 measurements, the difference was within ±150g — very good for a ¥79 scale. Day-to-day consistency is even better: if I weigh myself 3 times consecutively, I get the same reading. Accuracy is the most important feature of a scale and this delivers.” — SMZDM user

💡 Summary: Accuracy is excellent for the price point. Consistent readings within ±100-200g for daily tracking.

App Integration and Trends

“The Zepp Life app is the real value of this scale. Without it, it’s just a standard digital scale. With the app, I can see my weight trends over months. The goal-setting feature keeps me accountable. I sync it with Apple Health which integrates with my other health data.” — JD.com user

💡 Summary: App trend tracking adds significant value beyond simple weight measurement.

User Recognition

“My wife and I have similar weights (around 60kg and 65kg). The scale occasionally confuses us and attributes the reading to the wrong person. For most families with more distinct weights, it works perfectly. You can manually reassign readings in the app.” — JD.com user

💡 Summary: User recognition works well for distinct weight differences. Manual reassignment is always possible in the app.

No Body Fat

“I wish I had bought the Body Fat version for ¥30 more. Tracking just weight is limiting — body fat percentage gives a more complete picture of health. The basic body scale is great if you only care about weight, but the Body Fat version at ¥109 is a better investment.” — JD.com user

💡 Summary: The base model only measures weight. Consider the Body Fat version for comprehensive health tracking.

Battery Life

“Original batteries lasted 14 months. The app shows battery level. I expected to replace batteries every 6-8 months based on reviews, so 14 months was better than expected. Use quality alkaline batteries for best battery life.” — JD.com user

💡 Summary: Excellent battery life with quality batteries — typically 12-14 months.

Purchase Recommendations

✅ Worth Buying (¥79)

If you only need weight tracking with smartphone integration, the Xiaomi Body Scale 2 is the best value proposition on the market. The ¥79 price is aggressively competitive, and 600,000+ reviews confirm its reliability.

💰 Upgrade to Body Fat Scale (¥109)

For just ¥30 more, the Xiaomi Mijia Body Fat Scale adds body fat percentage, muscle mass, bone mass, water percentage, and more. If you’re serious about health tracking, that’s the smarter buy.

⚠️ Alternative: Huawei Scale 3 (¥129)

Choose the Huawei Scale 3 if you use Huawei Health ecosystem. It adds Wi-Fi connectivity (automatic sync without phone) and BIA body fat measurement with 8 composite metrics. Better for Huawei phone users.

FAQ

Q: What app does the Xiaomi Body Scale 2 work with? A: The scale works with Zepp Life (formerly Mi Fit) on both iOS and Android. Data can also sync to Apple Health, Google Fit, or Samsung Health via Zepp Life. You can also use the Xiaomi Wear app.

Q: Can I use the scale without a smartphone? A: Yes. The scale functions as a standard digital weight scale without the app. Step on, see your weight on the LED display, step off. You just lose the trend tracking, user recognition, and data export features.

Q: How is the scale different from the Xiaomi Body Fat Scale? A: The Body Scale 2 measures weight only (¥79). The Body Fat Scale (¥109) adds BIA bioelectrical impedance sensors in the glass surface and measures: weight, body fat percentage, muscle mass, bone mass, water percentage, BMI, basal metabolic rate, visceral fat, protein, and body age.

Q: Is the scale accurate? A: Yes, for the price point. Accuracy is approximately ±50g (claimed) and ±100-200g in real-world testing. This is sufficient for tracking weight trends over time, which is more important than absolute accuracy.

Q: Can the scale be used on carpet? A: You need to remove the rubber feet for carpet use (they are removable). Even then, accuracy on soft carpet is reduced. The scale is designed for hard, flat surfaces — tile, hardwood, laminate. For best accuracy, always use on the same surface.
