A power receiving apparatus, that complies with at least two power transfer methods and receives power wirelessly from a power transmitting apparatus, detects unexpected power which is not power transmitted from the power transmitting apparatus while a first power transfer method is used out of the at least two power transfer methods. When the unexpected power is detected, the power receiving apparatus controls the power transmitting apparatus and the power receiving apparatus so that a second power transfer method which is different from the first power transfer method out of the at least two power transfer methods is used.
