You don't need to worry because lifespan mode will automatically activate when the Battery Health Charging feature is enabled. sent, if we may know, was previously the maximum lifespan mode available in the MyAsus app? We inform you that the maximum lifespan mode is not available in the MyAsus app it could be because your unit uses an Intel Gen 12th or Intel Alderlake processor. Sorry for the inconvenience and we have seen the attachment. And this is what the service center from asus told me.
