An electronic device, according to various embodiments, may comprise a wireless transmission circuit for transmitting power to a power reception device, and a first processor. When entering power reduction mode, the first processor may: if the power reception device is in an align state with respect to a first voltage and a first current being output from the wireless transmission circuit, lower the voltage of the wireless transmission circuit to a second voltage lower than the first voltage and lower the current flowing through the electronic device to a second current lower than the first current; and if the power reception device is in a misalign state, lower the voltage of the electronic device to a third voltage lower than the second voltage and lower the current flowing through the wireless transmission circuit to a third current lower than the second current. La présente invention concerne, selon divers modes de réalisation, un dispositif électronique pouvant comprendre un circuit de transmission sans fil utilisé afin de transmettre de l'énergie à un dispositif de réception d'énergie et un premier processeur. Lors de l'entrée en mode de réduction d'énergie, le premier processeur peut : si le dispositif de réception d'énergie est dans un état d'alignement par rapport à une première tension et qu'un premier courant est délivré par le circuit de transmission sans fil, abaisser la tension du circuit de transmission sans fil à une deuxième tension inférieure à la première tension puis abaisser le courant circulant au travers du dispositif électronique à un deuxième courant inférieur au premier courant ; et si le dispositif de réception d'énergie est dans un état mal aligné, abaisser la tension du dispositif électronique à une troisième tension inférieure à la deuxième tension et abaisser le courant circulant à travers le circuit de transmission sans fil à un troisième courant inférieur au deuxième courant. 다양한 실시예에 따른 전자 장치는 전력 수신 장치로 전력을 전송하는 무선 송신 회로 및 제1프로세서를 포함할 수 있다. 제1프로세서는 전력 감소 모드 진입 시, 무선 송신 회로에서 출력되고 있던 제1전압 및 제1전류에 대하여 전력 수신 장치가 얼라인(align) 상태인 경우, 무선 송신 회로의 전압을 제1전압보다 낮은 제2전압으로 하강시키며, 전자 장치에 흐르는 전류를 제1전류보다 낮은 제2전류로 하강시키고, 전력 수신 장치가 미스 얼라인(misalign) 상태인 경우, 전자 장치의 전압을 제2전압보다 낮은 제3전압으로 하강시키며, 무선 송신 회로에 흐르는 전류를 제2전류보다 낮은 제3전류로 하강시킬 수 있다.
