Fitness tracking and health: Sensor accuracy
Today’s smartwatch is primarily a tool for monitoring health, and in 2026, data analytics algorithms have become much more accurate, with Xiaomi’s new BioTracker sensors capable of measuring not only heart rate and blood oxygen (SpO2), but also ECG analysis at home, making them a serious competitor to specialized medical gadgets.
Not only is the pulse important for athletes, but the quality of the route tracking, and the flagship models have two navigation systems, which is critical for runners in megacities, and the algorithms for recognizing swimming, running and cycling automatically determine the type of activity and start recording if you forget to start the track manually.
- 🫀 Monitoring Stress and Breathing Quality 24/7.
- 🏃♂️ Automatic recognition of 6 major sports.
- 💤 Advanced sleep phase analysis with recommendations.
- 🩸 Measurement of blood oxygen levels and pulse variability.
⚠️ Health data obtained from smart watches are informative and cannot be used to make medical diagnoses without consulting a doctor.
It is worth noting that the accuracy of measurements depends on the density of the strap to the wrist, too loose fit can distort the readings of the optical pulse sensor, especially during intensive training.
💡
For maximum accuracy of pulse measurement during sports wear a watch 2-3 centimeters above the wrist bone and tighten the strap, but not passing blood flow.
Ecosystem and compatibility with iOS and Android
One of the main issues when buying is compatibility. Xiaomi watches work with both types of operating systems, but the functionality can vary. Android users have a full range of options, including quick responses to messages (depending on the phone model) and music management. iPhone owners can also use gadgets, but with some restrictions.
There are no quick notification responses on iOS, and there may be restrictions on installing some dials or updating firmware through third-party apps. However, basic activity tracking, notifications and data synchronization work consistently. The Mi Fitness app (formerly Xiaomi Wear) is used to manage it, which is a single hub for all the brand’s devices.
Xiaomi’s smart home integration allows you to use the watch as a remote control. You can turn off the lights, run robot vacuum cleaners, or check the security cameras right from your wrist. This is especially convenient when the phone is in another room or in your pocket.
