摘要：
A method is provided for optimizing wireless charging of a mobile device by a wireless charger. The method comprises successively reducing transmit power in the wireless charger until an operating wireless transmit power is reached when a power loss occurring during a wireless transmission of power is caused by magnetic saturation, wherein the magnetic saturation occurs in at least one of the mobile device and the wireless charger, wherein the wireless transmission of power is from the wireless charger to the mobile device, and wherein the magnetic saturation is reduced at the operating wireless transmit power, and disabling charging by the wireless charger when the power loss occurring during the wireless transmission of power is caused by a foreign object is present between the mobile device and the wireless charger.
