Qualcomm wireless tech will recharge metal

WiPower now universal

Qualcomm WiPower will now charge phones with metal cases, breaking a barrier which had prevented wireless charging on more expensive models. 

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.

Steve Pazol, General Manager at Wireless Charging, Qualcomm said that building a wireless charging solution into devices with metal exteriors was a significant step for moving the entire industry forward.

"Today, more device manufacturers are choosing to use metal alloys in their product designs to provide greater support and, of course, aesthetics. QTIs engineering advancement removes a major obstacle facing wireless power and opens the continued adoption of this desirable feature to a much wider range of consumer electronics and use cases."

WiPower works at a frequency that is more tolerant of metal objects that come within the charge field.

Objects such as keys and coins in the charge field and do affect the charging. WiPower has added the ability to have the device made of metal. This advance preserves WiPower's existing ability to charge devices needing up to 22 watt at faster speeds when compared to other wireless charging technologies.

Based on Near Field Magnetic Resonance technology, WiPower enables greater flexibility and convenience in wireless charging. This allows for a wide range of compatible consumer-electronic and handset devices to charge without precise alignment or direct physical contact.

The technology enables simultaneous charging of multiple devices with different power needs while using Bluetooth Smart to reduce hardware needs.
