Body Battery
Your device analyzes your heart rate variability, stress level, sleep quality, and activity data to determine your overall
Body Battery™ level. Like a gas gauge on a car, it indicates your amount of available reserve energy . The
Body Battery level range is from 0 to 100, where 0 to 25 is low reserve energy, 26 to 50 is medium reserve energy, 51 to 75 is high reserve energy, and 76 to 100 is very high reserve energy.
