Samsung, Qualcomm and others join hands on ‘Rezence’, a resonance wireless charging standard

In the middle of October, a rumor emerged suggesting Samsung was working on introducing magnetic resonance wireless charging in its phones in 2014, and now it looks like the company has taken a step towards achieving that goal. The Alliance for Wireless Power (A4WP) has announced that it will launch a certification program for devices for resonant wireless charging¬†at the end of this year, under the brand name “Rezence.” Samsung is a part of A4WP, along with LG, Qualcomm and a few other companies, and it’s easy to see where the rumor found its feet back in October.

Rezence is a mix of the words “resonant” and “essence,” with its symbol a lightning bolt inside a pair of brackets, and it will go up against wireless charging standards like Qi (by the Wireless Power Consortium) and Power 2.0 (by the Power Matters Alliance) – Samsung is a part of all three alliances, but it looks like resonant charging is where the company might be putting most of its focus. For those unaware, resonant¬†charging uses tuned electromagnetic resonators to deliver power at a distance, which means that devices would no longer have to be perfectly aligned with their charging pads, or even touching them in some cases.
