Abstract
Certain aspects of the present disclosure are generally directed to apparatus and techniques for wirelessly charging a device. An exemplary method generally includes receiving, at a first wireless power transfer device, a synchronization signal indicative of a phase for generating a wireless charging field, determining an adjusted phase for generating the wireless charging field based, at least in part, on the received synchronization signal and one or more measurements taken at least one of the first wireless power transfer device or a second wireless power transfer device, wherein the one or more measurements are indicative of a phase difference between the first wireless power transfer device and the second wireless power transfer device, and generating, at the first wireless power transfer device, the wireless charging field with the adjusted phase.
