1. A wireless power transfer (WPT) enabled device, comprising:
- a driver module configured to provide a power signal for wireless power transfer to a second WPT-enabled device according to default transfer parameters, including a magnetic or electric field of a nominal intensity, associated with an initial power transfer phase; and
a controller module configured to;
store, in a memory, an operating parameter and a unique identifier from the second WPT-enabled device during the initial power transfer phase;
adjust the initial power transfer phase to a refined power transfer phase based on the operating parameter; and
enable the driver module to wirelessly transfer power subsequent to the initial power transfer phase according to updated transfer parameters associated with the refined power transfer phase by correlating the unique identifier with the stored operating parameter of the second WPT-enabled device.

Abstract
An apparatus and method are disclosed to increase the efficiency of communications between wireless power transfer (WPT) devices. During an initial power transfer and/or communication between WPT devices, characteristics regarding the operation and capabilities of the devices are shared and stored on one or both of the WPT devices. On subsequent power transfers and/or communications, a WPT device can quickly match the capabilities and preferences for the same WPT device. Various systems are presented to generate, access, and implement the stored information to quickly tailor and improve a communication session for a specific WPT device.
