Qualcomm has announced that it has engineered a new solution which will allow wireless charging for devices that have metal cases. The solution uses Qualcomm’s WiPower technology and is designed to be compliant with the Rezence standard, Qualcomm says that this is the first announced solution to support wireless charging for mobile devices that are fashioned out of metal.
Wireless charging isn’t a new technology but it’s not really mainstream, only a handful of new devices released this year support the technology but there’s hope that things will be much better in the future particularly when support for fast charging arrives.
Manufacturers like HTC who fashioned their flagship handsets such as the One M9 out of metal can’t offer wireless charging due to limitations presented by the material but Qualcomm’s solution to get a device to charge through a metal back cover is going to appeal to such manufacturers.
The solution and the full suite of WiPower reference designs are available starting today to WiPower licensees, it retains WiPower’s current ability to charge devices requiring up to 22 watts.
WiPower is based on Near Field Magnetic Resonance technology which allows for greater flexibility and convenience in wireless charging, it also enables simultaneous charging of multiple devices with different power requirements using Bluetooth Smart in order to limit hardware requirements.
