A method for reducing radiation damage from a mobile terminal, characterized in that the method comprises steps of: A, response to the mobile terminal being in a call answering state, if a main transceiver path of the mobile terminal is switched to an upper antenna, proceeding to step B; B, response to a detecting of an earpiece of the mobile terminal, if the earpiece of the mobile terminal is in a working state, proceeding to step C, wherein the step B comprises: B1, detecting whether a working statement indicating the earpiece open appears in a hardware abstraction layer (HAL layer) code of the mobile terminal, determining whether the earpiece of the mobile terminal is in the working state according to a detecting result; B2, when the working statement indicating the earpiece open appears in the HAL layer code of the mobile terminal, then determining that the earpiece of the mobile terminal is in the working state, and proceeding to step C; B3, when the working statement indicating the earpiece open does not appear in the HAL layer code of the mobile terminal, then determining that the earpiece of the mobile terminal is in a non-working state, and ending process; C, reducing a radio frequency transmit power of the upper antenna of the mobile terminal, so as to reduce a radiation damage from the mobile terminal to a user.
