The invention discloses a remote controller energy-saving control method with zero standby power consumption. The method comprises the following steps: a) circuit setting; b) starting a remote controller; c) voltage output holding; d) detecting the state of the remote controller; and e) zero power consumption standby of the remote controller. The remote controller energy-saving control circuit with zero standby power consumption comprises a battery BAT, a DC-DC chip U1, a remote controller logic processing chip U2 and a non-self-locking key KEY1, one end of the non-self-locking key KEY1 is connected with the positive electrode of the battery BAT, and the other end of the non-self-locking key KEY1 is connected with the negative electrode of the battery BAT. And the other end of the DC-DC chip U1 is connected with a pin PX on the remote controller logic processing chip U2 and is connected with an enabling pin EN on the DC-DC chip U1 directly or through a phase inverting circuit at the same time.
