What is the battery lifetime and operational time of my M400?
The battery operating time in continuous training with GPS recording and heart rate is up to 8 hours. M400 can be in time mode with daily activity monitoring for approximately 30 days.
Battery operating time depends on many factors, such as the temperature of the environment in which you use your training device, the features and sensors you use, and battery aging. The use of compatible sensors, and frequent syncing with Flow app will also decrease the battery life.
