1. An electronic device comprising:
an optical sensor configured to emit a reference light to a reference object and detect the reference light reflected from the reference object during calibration, and emit a measurement light to a target object and detect the measurement light reflected from the target object during a measurement;
a display; and
a processor configured to:
when the electronic device is placed on a charger and is in a charging state, perform the calibration of the optical sensor based on the reference light reflected from the reference object;
control the display to output operational instructions for estimating bio-information according to progress stages of the measurement after charging of the electronic device;
calculate absorbances at each wavelength of the measurement light based on a light quantity of the reference light that is measured during the calibration, and a light quantity of the measurement light measured from the target object;
obtain a feature value based on the absorbances calculated at each wavelength of the measurement light; and
estimate the bio-information based on the obtained feature value.
