The Apple Watch uses your age, gender, height and weight, in addition to the GPS in your iPhone and data from its own built-in sensors, to calculate both your resting calories and ones you burn during exercise.
Apple Watch is supposed to have 18 hours of battery life, which would translate into a full day if I were to ever keep to a normal sleeping schedule.
