Abstract: Wireless charging, such as that conducted according to standards formed by the AirFuel Alliance and/or various other industry standards for wireless charging, can cause interference with data transfer on a cellular modem of a mobile device. Systems, devices, and methods herein provide power breaks where a power transmitter unit (PTU) will stop generating an electromagnetic field used to charge a power receiver unit (PRU). During the power break, the mobile device can send or receive data over the cellular modem with less or no interference from the wireless charging operations. If the PTU cannot provide a power break, the PRU de-tunes a receive resonator circuit in the PRU to mitigate the interference from the wireless charging operations. Further, the power breaks can also be used by PTUs to scan for near field communication (NFC) tags or devices that could be damaged by wireless charging activities.
