Qualcomm supports wireless charging for smartphones metal housing




Qualcomm has found a way to combine technology for wireless charging with metal housings. The manufacturer uses its existing magnetic resonance and can then load with a maximum power of 22W.

Qualcomm claims to be the first manufacturer to be bringing wireless charging for devices with metal housing. The works commonly used Qi standard for smartphones based on induction and is not suitable for metal. Qualcomm puts his competitive WiPower on the basis of the standard in-Rezence.

This technology uses magnetic resonance to 6,78MHz, so it was possible to explain as keys and other metal objects on a charging surface, without charging frustrated. With the new changes can also recharge your device have a metal housing. “The improvement of WiPower retains the ability to load devices that require 22W, at speeds which are equal to or higher than other wireless charging techniques,” claims Qualcomm.

Rezence offers even supports devices such as tablets and laptops, with a payload of up to 50W. One of the advantages of the technique is that different devices can be loaded on a single surface, and that a direct connection with the surface is not required.
