A method of operating a wireless-power receiver comprises: determining a first resonant frequency of a resonant circuit, of the wireless-power receiver, corresponding to a first time at which the wireless-power receiver is disposed at a first longitudinal offset from a power transmitter, the first longitudinal offset being relative to a length of a device containing the wireless-power receiver; determining a second resonant frequency of the resonant circuit, corresponding to a second time at which the wireless-power receiver is disposed at a second longitudinal offset from the power transmitter, the second longitudinal offset being relative to the length of the device containing the wireless-power receiver, and the first longitudinal offset being different from the second longitudinal offset; and determining a lateral misalignment of the wireless-power receiver relative to a wireless-power transmitter based on the first resonant frequency and the second resonant frequency.
