1. A method of adapting charging for an accessory device, the method comprising:
at a charging device:
transmitting a first power signal with a first transmission amplitude;
measuring a receiving load of the first power signal;
determining based on the measured receiving load whether a response signal is received from the accessory device; and
if the charging device does not receive the response signal, transmitting a second power signal at a second transmission amplitude that is lower than the first transmission amplitude so as to reduce potential magnetic saturation.
