The Amazfit Band 5 is not the most independent wearable you’ll find. Despite the hard-to-view display, it offers a number of metrics that you can pull up once you’ve performed an activity in one of the 11 different sport modes. The continuous heart rate sensor not only measures your heart rate throughout your workout, but also breaks down how many minutes you spend in the different heart rate zones, which range from relaxed to intense to anaerobic.
Fitbit’s new Activity Zone Minutes metric strips away some of the more complicated features of its Activity Zone feature on the Charge 4. The Charge 4 can calculate your target heart rate zones based on your age and resting heart rate, and track your progress toward the goal of spending 150 minutes per week in that zone. Monitoring blood oxygen (SpO2) is an important health tool these days, and Fitbit has stripped away some of the more subjective features from its Activity Zone feature to make it a more objective metric. Below-average blood oxygen levels (95 percent or less) can be a sign of health problems. A SpO2 measurement is also less subjective than a pulse or blood pressure measurement. ..
The Amazfit Band 5 is a new fitness band that claims to last up to 15 days on a charge. It has a battery life of up to 2 hours, which is more than the battery life of the Fitbit Charge 4. If it does need to be charged, it takes less than two hours with the Amazfit’s own charger. The Amazfit Band 5 is also one of the most affordable fitness bands on the market.
The Amazfit Band 5 is a more viable sleep tracker than most other wearables on the market. Although accuracy fluctuated over the course of several nights, especially when I slept in and out while streaming Umbrella Academy on Netflix, I was usually credited with just a few more minutes of sleep than the Apple Watch. ..
