Une première face où se situe l'écran d'affichage d'un premier dispositif électronique est tournée vers le haut, une deuxième face opposée à la première face est tournée vers le bas, la deuxième face est en contact avec l'une ou l'autre face d'un second dispositif électronique ; ou la première face est en contact avec une quatrième face où se situe l'écran d'affichage du second dispositif électronique ; le premier dispositif électronique charge sans fil le second dispositif électronique ou reçoit une charge sans fil en provenance du second dispositif électronique. Ledit procédé comprend : un premier dispositif électronique recevant des premières informations d'état de batterie en provenance d'un second dispositif électronique, les premières informations d'état de batterie représentant la situation de niveau de batterie actuelle du second dispositif électronique ; et le premier dispositif électronique affichant les premières informations d'état de batterie sur l'écran d'affichage du premier dispositif électronique. De cette manière, dans un scénario de charge sans fil, lorsqu'un dispositif chargé et un dispositif d'alimentation électrique sont placés dos à dos, le dispositif situé sur la couche supérieure peut afficher des informations de niveau de batterie du dispositif situé sur la couche inférieure, de manière à faciliter la prise de connaissance du niveau de batterie du dispositif situé sur la couche inférieure par un utilisateur.
