What is the battery lifetime and operational time of my M430?
The M430 has an internal, rechargeable battery.
The battery operating time is:
- up to 8 hours training with GPS and optical heart rate, or
- up to 30 hours training with GPS power save mode and optical heart rate, or
- up to 50 hours training with GPS power save mode and Bluetooth Smart heart rate sensor, or
- when used only in time mode with daily activity monitoring, the operating time is approximately 20 days.
Keeping the Continuous Heart Rate feature on in your M430 will drain the battery quicker.
The operating time depends on many factors, such as the temperature of the environment in which you use your M430, the features and sensors you use, and battery aging. Smart notifications and frequent syncing with Flow app will also decrease the battery life. The operating time is significantly reduced in temperatures well below freezing. Wearing the M430 under your overcoat helps to keep it warmer and to increase the operating time.
