The invention provides a method for adjusting transmission power, apparatus, storage medium and signal transceiver. The method comprises the following steps: an acquiring step of acquiring a retransmission rate of data currently transmitted by the signal transceiver; a first judging step of judging whether the retransmission rate acquired by the acquiring step exceeds a set retransmission rate threshold; and an adjusting step for adjusting a current transmission power of the signal transceiver according to a set maximum transmission power of the signal transceiver if the retransmission rate exceeds the set retransmission rate threshold value in the first judging step. The scheme provided by the invention can provide reasonable transmission power while ensuring the communication quality, sothat the signal transceiver does not need to maintain the maximum transmission power all the time, and the transmission power consumption of the device is reduced.
