14 DAY TRIAL // Chipset maker Qualcomm claims it can now wirelessly charge smartphones with metal cases. According to the company, this is possible thanks to its new “WiPower” technology, which is designed to be compliant with the Rezence standard.
Qualcomm confirmed that the patent for designing a device that can charge through a metal back cover, along with the full suite of WiPower reference designs are available to WiPower licensees.
According to the company, its new technology that meets the Rezence standard can operate at a frequency that is more tolerant of metal objects that come within the charge field.
Until today, it was possible to have objects such as keys and coins in the charge field and not affect the charging processor, but WiPower adds the ability to have the device itself made of metal.
Qualcomm's WiPower technology requires up to 22 watts to charge devices with metal cases, at speeds equal or faster when compared to other wireless charging technologies.
So, this is not only a brand-new technology that can wirelessly charge smartphones with metal cases, but it might also be faster than other technologies available on the market.
Multiple devices can be charged at the same time
WiPower is based on Near Field Magnetic Resonance technology and offers larger flexibility and a wide range of compatible electronic products and handset devices to charge without the need for precise alignment or direct physical contact.
Qualcomm also states that the new WiPower technology enables simultaneous charging of multiple devices with different power requirements while using Bluetooth Smart to minimize the hardware requirements.
“Today, more device manufacturers are choosing to utilize metal alloys in their product designs to provide greater structural support and, of course, aesthetics.
“QTIs engineering advancement eliminates a major obstacle facing wireless power and opens up the continued adoption of this desirable feature to a much wider range of consumer electronics and use cases.” said Steve Pazol, general manager of Wireless Charging, Qualcomm Incorporated.
