How long does the A370 battery last?
The battery operating time is up to 4 days with 24/7 activity tracking, continuous HR tracking on and 1h/day training without Smart Notifications on.
The operating time depends on many factors, such as the temperature of the environment in which you use your A370, the features you use, are notifications on and how many you receive, how active you are, how much the display is on and battery aging. The operating time is significantly reduced in temperatures well below freezing. Wearing the A370 under your overcoat helps to keep it warmer and to increase the operating time. Also, the amount of training sessions you do with wrist-based heart rate or with a H10 Bluetooth heart rate sensor affect it too. The operating time could roughly double if you turn continuous HR tracking off.
