Huawei Watch GT Pro - Heart Rate Sensor

[walkerstorm]

I find that during extensive exercise, the heart rate sensor measures low compared to my mi band 3. Is this a common problem with the GT Pro?

Personally I believe these smartwatch heart rate monitors without chest bands are approximations at best. Might work ok at rest but not so good exercising.

None of these sensors are medical grade. Ok for casual use but I agree that a chest band is best for an accurate heart rate monitor.
