1. A method, comprising:

  • capturing, using a heart rate sensor, heart rate data from a user, where the heart rate sensor is coupled with a mobile device;

    providing the heart rate data to a heart rate calculator for determining a heart rate of the user;

    monitoring an activity state of the user from activity data captured by the mobile device; and

    detecting, using a processor, a constant activity state of the user based on the captured activity data;

    wherein, when the constant activity state is detected;

    stopping, using the processor, the capture of new heart rate data during a period in which the user remains in the constant activity state,inferring, using the processor, heart rate data for the user from the captured heart rate data during the period in which the user remains in the constant activity state regardless of an activity level of the user,providing, using the processor, the inferred heart rate data to the heart rate calculator, anddetermining, using the heart rate calculator, the heart rate of the user based on the inferred heart rate data during the period in which the user remains in the constant activity state.
