Abstract: The present disclosure relates to an apparatus and a method for controlling power consumption for monitoring a sensor state in an electronic device. The electronic device can stop checking the state of at least one sensor until a radio resource control (RRC) connection is maintained, and a cumulative electromagnetic wave specific absorption rate (SAR) reaches a preset threshold value (SAR_threshold). The cumulative electromagnetic wave specific absorption rate may be an electromagnetic wave specific absorption rate accumulated by transmission power transmitted within a time period corresponding to a time slot using a specific frequency band.
