Abstract
A method and a system for reducing radiation damage from a mobile terminal are provided. The method includes the following steps: responsive to the mobile terminal being in a call answering state, switching a main transceiver path of the mobile terminal to an upper antenna; and responsive to a receiver of the mobile terminal is in a working state, reducing a radio frequency transmit power of the upper antenna of the mobile terminal. When determining that the user is in a call while being close to the mobile terminal and that the main transceiver path is switched to the upper antenna, the present disclosure reduces the radio frequency transmit power of the upper antenna, of the mobile terminal by a radio frequency chip, thereby reducing an SAR value so as to prevent the radiation of the mobile terminal from harming the user.
