*Your actual battery life may vary depending on usage and conditions. If you enable the Ultra battery mode it will increase battery life, but deactivate wrist heart rate tracking. In Endurance battery mode, battery life is 40 hours with wrist heart rate and 60 hours with HR belt. Touch is disabled during exercise, but you can activate it in your custom mode.
