Advanced Body Composition Analysis
The Xiaomi Mijia S400 is designed to help users look beyond a single weight reading. Using dual-frequency bioelectrical impedance analysis (BIA), it estimates body composition by measuring the body's electrical impedance and processing the results through its measurement algorithms.Compatible app reports can include body weight, BMI, body fat percentage, fat mass, muscle mass, skeletal muscle mass, body water, protein mass, bone mineral content, visceral fat rate, basal metabolic rate, and other indicators. These measurements can help users follow general trends as they work toward fitness or weight-management goals.Important: Body composition values are estimates, not medical diagnoses. Results can vary with hydration, recent exercise, meals, skin contact, and measurement conditions. Use consistent measurement conditions to compare trends over time rather than treating individual readings as definitive medical results.Dual-Frequency BIA Measurement Technology
The S400 uses dual-frequency bioelectrical impedance analysis to gather information about the body's electrical response at different frequencies. The scale processes these measurements to estimate body composition metrics such as fat mass and body water.Its enlarged electrode contact areas are designed to improve electrical contact during measurements. For the most consistent results, stand barefoot on the scale with both feet positioned properly on the electrodes and follow the instructions in the Xiaomi Home app.Although the technology provides more information than weight-only measurement, it does not replace clinical body composition testing or professional medical assessment.Static Heart Rate Monitoring
The Xiaomi Mijia Body Composition Scale S400 includes a static heart rate monitoring function. It can measure the user's heart rate while standing still during the measurement process, adding another data point to the scale's general wellness reports.Heart rate monitoring is intended for general tracking and should not be used to diagnose a heart condition. Readings may be affected by movement, measurement technique, and other factors. If you have concerns about your heart rate or experience symptoms, consult a qualified healthcare professional.Smart Bluetooth Connectivity and Xiaomi Home App
The scale connects through Bluetooth Low Energy 5.0 and is designed to work with the Xiaomi Home (Mi Home) app. After compatible pairing, users can access detailed body composition reports and review previous measurements to observe changes over time.The Chinese Version may require the Xiaomi Home app region to be set to Chinese Mainland for device discovery and setup. Regional account settings, app versions, and firmware compatibility can affect the pairing process, so verify compatibility before purchasing.The S400 is listed as compatible with Xiaomi Home rather than Mi Fitness or other third-party fitness apps. Automatic cloud synchronization and remote access to measurement history may require a compatible Bluetooth gateway, which is generally sold separately.Family-Friendly Design with Up to 36 User Profiles
The Xiaomi S400 can support up to 36 user profiles, making it suitable for households where several people want to track their measurements on the same device. Individual profiles help organize measurements and make it easier to review personal trends through the app.Xiaomi specifies body composition measurements for users aged 6 to 80 years, subject to its supported measurement conditions. For children under 6 and adults over 80, the scale is intended for weight measurement only. Measurements for adolescents should be treated as reference information because their bodies are still developing.Automatic user identification may not reliably distinguish users whose body weights are within approximately 2kg of one another. In these cases, manual user selection in the app may be required.Multiple Weighing Modes for Everyday Convenience
The S400 offers several weighing modes that can be selected through the supported Xiaomi Home app configuration. These modes extend its usefulness beyond standard adult body weight measurements.- Standard weighing: Measure body weight and, where supported, additional body composition metrics.
- Baby or holder mode: Help weigh an infant or pet by measuring the difference between the holder's weight with and without the child or pet.
- Small-object weighing: Measure suitable objects within the supported 0.1kg to 10kg range.
- Guest mode: Allow visitors to weigh themselves without saving their measurement data to the regular user history.
- Balance testing: Access a supported balance-related assessment through the app.
Minimalist Design and Stable Weighing Platform
With dimensions of approximately 300 × 300 × 24.55mm and a net weight of about 1.45kg, the Xiaomi S400 has a clean, low-profile design that fits comfortably in many bathrooms, bedrooms, and home fitness areas.The platform uses reinforced glass and engineering plastic, with enlarged anti-slip contact areas intended to improve stability during use. Place the scale on a hard, flat surface to support consistent readings. Avoid using it on carpets, uneven floors, or wet surfaces.Long Battery Life and Convenient Operation
The Xiaomi Body Composition Scale S400 is powered by three AAA alkaline batteries and has a rated voltage of 4.5V. Xiaomi advertises battery life of up to approximately 180 days under specified laboratory testing conditions.Actual battery life varies with usage frequency, wireless connectivity, environmental conditions, and battery quality. The scale also provides a low-battery indication to help users know when replacement is needed.Xiaomi Mijia Body Composition Scale S400 Specifications
