This disclosure provides systems, methods and apparatuses for preventing power transfer in a secondary coil of a wireless power reception apparatus. Some implementations relate generally to the use of one or more switches. In some implementations, the one or more switches may be coupled in series to one or both ends of the secondary coil. The one or more switches may be controlled based on a handshake communication between the wireless power reception apparatus and a compatible wireless power transmission apparatus. The one or more switches may be controlled using bias power from a wireless communication interface that is separate from a power reception circuitry that includes the secondary coil. The one or more switches may disable power transfer in the secondary coil to protect one or more components of the wireless power reception apparatus or to enable measurement of a coupling factor during measurement periods.
