1. A method for wireless power transfer, comprising:
providing, by a wireless power transmitter, power transfer coverage for a plurality of peripheral devices configured to receive wireless power from the wireless power transmitter;
gradually decreasing an amount of transmission power of the wireless power transmitter until a first peripheral device of the plurality of peripheral devices is disconnected from the power transfer coverage of the wireless power transmitter; and
controlling an output power of the wireless power transmitter based, at least in part, on the amount of transmission power when the first peripheral device is disconnected.
