Xiaomi Body Composition Scale S400 with 25 Health Metrics
Maintaining a healthy lifestyle is about more than simply checking your weight. Understanding your body composition can help you make smarter fitness and nutrition decisions. The Xiaomi Body Composition Scale S400 is designed to provide a detailed picture of your health by measuring 25 body composition indicators using advanced dual-frequency Bioelectrical Impedance Analysis (BIA) technology. Available in Pakistan, it offers premium health tracking at an affordable price. If you're wondering whether the Xiaomi S400 is worth buying, this review covers its design, features, accuracy, pros, cons, and overall value to help you make an informed decision.

Premium Design with a Minimalist Look
The Xiaomi Body Composition Scale S400 follows Xiaomi's signature minimalist design. It features a reinforced glass surface combined with durable engineering plastic, giving it a premium appearance while ensuring long-lasting durability. Measuring 300 × 300 × 24.55mm, the scale has a slim profile that fits neatly into any bedroom or bathroom.
Its large LED display provides clear readings, while the hidden screen lights up automatically when you step onto the scale. The anti-slip feet improve stability, making every measurement safe and reliable.
Advanced Body Composition Analysis
Unlike traditional weighing scales that only display your weight, the Xiaomi S400 delivers a comprehensive health report by measuring 25 different body indicators. This allows users to understand changes in their body beyond simple weight loss or gain.
Some of the key health metrics include:
- Body Weight
- Body Fat Percentage
- BMI (Body Mass Index)
- Muscle Mass
- Skeletal Muscle
- Body Water Percentage
- Protein Level
- Bone Mass
- Basal Metabolic Rate (BMR)
- Visceral Fat
- Heart Rate
- Body Age
- Fat-Free Body Weight
These detailed insights help users track fitness progress, improve workout routines, and maintain healthier lifestyles.

Dual-Frequency BIA Technology
One of the biggest advantages of the Xiaomi S400 is its dual-frequency BIA measurement technology. Unlike many budget smart scales that rely on a single frequency, the S400 uses two different electrical frequencies to analyze body composition more accurately.
This technology improves the estimation of body fat, muscle mass, and water percentage, making the results much closer to professional body composition analyzers. While it should not replace medical equipment, it provides highly useful data for everyday health monitoring and long-term progress tracking.
Smart App Connectivity
The Xiaomi Body Composition Scale S400 connects to the Mi Fitness app through Bluetooth 5.0, allowing users to sync and store all measurements automatically.
The app provides:
- Historical health records
- Body composition trend charts
- Fitness progress tracking
- Personalized health insights
- Easy data sharing
Instead of manually recording measurements, every reading is saved automatically, making it simple to monitor improvements over weeks and months.

Supports Multiple Users
The Xiaomi S400 is ideal for families because it supports multiple user profiles. Each family member can create their own profile within the Mi Fitness app, and the scale intelligently recognizes different users based on previous measurements.
This feature allows everyone to keep their personal health records separate without needing multiple devices.
Easy to Use
Using the Xiaomi S400 is straightforward:
- Install three AAA batteries.
- Pair the scale with the Mi Fitness app.
- Step onto the scale barefoot.
- Wait a few seconds while the analysis completes.
- View detailed results instantly on your smartphone.
The entire process takes only a few seconds, making daily health tracking effortless.
