Accuracy of Digital watch-How effective is your latest digital watch? One such study done by University of Michigan of Samsung watches. Last year Samsung partnered with the University of Michigan, specifically the Michigan Performance Research Laboratory (MiPR), to study and improve the accuracy of measurements provided by its Galaxy Watches.

What was finding by MiPR?
The MiPR studies found high correlation between the data reported by the Galaxy Watches and sport science reference devices when measuring heart rate, body fat percentage, sweat loss and VO2 max (the last two features were introduced with One UI 4.1). Here’s the breakdown:
Accuracy of Digital Watch
- Heart rate: probably the most commonly used health feature on a watch, the study showed a 90% correlation with electrocardiogram equipment when running (which is trickier than measuring when standing still since the watch bounces around constantly).
- Body fat percentage: here the watches did even better, showing a 95% correlation with the standard diagnostic test of dual-energy X-ray absorptiometry .
- Sweat loss: this is a measurement of the amount of water a runner has lost during their run and is used to guide rehydration afterwards. The watches achieved 95% correlation when tested on distances ranging from 2.5km to 20km (1.5-12 miles).
- VO2 max: this measures how much oxygen is absorbed by the body during a workout. Compared to clinical-grade equipment, the watches achieved an acceptable correlation of 82%.
