Abstract: Embodiments of the invention disclose a method for reducing electromagnetic wave absorptivity in an LTE working mode. The method comprises the following steps of starting a proximity detector of a terminal when a receiver of the terminal is detected to be opened and the terminal is in the LTE working mode; detecting whether a detection object exists in a preset distance range through the proximity detector; and if the detection object is detected to exist in the preset distance range, carrying out power back-off on the maximum signal output power of the terminal to make the electromagnetic wave absorptivity corresponding to the signal output powder after power back-off smaller than or equal to a preset electromagnetic wave absorptivity threshold. The embodiments also disclose a terminal. Through adoption of the method and the terminal, the power back-off is only carried out on the signal output power of the terminal in the LTE voice mode, so that the electromagnetic wave absorptivity of a human body by the terminal is reduced while the communication efficiency of the terminal is improved.
