A power receiving apparatus comprises a power receiving unit that receives first power or second power from a power transmission apparatus; and a control unit that (a) requests the power transmission apparatus to transmit the first power, (b) determines whether or not a battery is a genuine battery by using the first power transmitted from the power transmission apparatus, (c) requests the power transmission apparatus to transmit the second power, when the battery is not a genuine battery, and (d) notifies a user of a reason why the battery is not being charged by using the second power transmitted from the power transmission apparatus.

Power receiving apparatus and control method

An electronic apparatus includes a support unit, a movement unit that moves an apparatus supported by the support unit, a communication unit, and a control unit. In a case where a connection for wireless communication to a communication apparatus is established via the communication unit, the control unit controls the movement unit to move the apparatus supported by the support unit. The control unit controls the communication unit to receive information about movement of the communication apparatus from the communication apparatus. The control unit determines whether the support unit is supporting the communication apparatus based on the information about the movement of the communication apparatus.
