Qualcomm Technologies has engineered a solution to allow wireless charging for devices with metal exteriors.
The solution, which uses Qualcomm WiPower technology, is designed to be compliant with the Rezence standard and becomes the first announced solution to support wireless charging for metal devices.
The techniques for designing a device to charge through a metal back cover, as well as the full suite of WiPower reference designs, are available today to WiPower licensees.
Though the ability to charge smartphones and other devices without wires offers convenience to consumers, charging a device with a metal exterior has been incompatible with wireless charging technologies.
Steve Pazol, general manager of Wireless Charging, Qualcomm, said: “More device manufacturers are choosing to utilize metal alloys in their product designs to provide structural support and, of course, aesthetics.”
WiPower has added the ability to have the device itself made of metal. This technology advancement maintains WiPower’s existing ability to charge devices requiring up to 22 watts today, at speeds equal to or faster when compared to other wireless charging technologies.
