Honor Band 3 had been in use for three years before to this (pedometer, sleep phases - with good accuracy). I wanted the same cool device from the HB5 that adds additional chips to carry out the stated functions. What actually happened was: 1. The track switching function on an iPhone defeats the purpose entirely. 2. The pedometer has a significant inaccuracy (two steps are equal to 10 steps when walking in a vehicle). 3. Notices any immobility when in the light sleep phase. 4. Measurement of oxygen and pulse (quite reliable measurements) for pampering 5. Day 4 and 5 autonomy Regrettably, the result fell short of expectations. It serves no purpose as a pedometer. The earlier product is of far higher quality.
