Samsung is preparing to launch a new wireless charger, one which will be able to charge any device no matter of the technology.
There are two methods of wireless charging. One in magnetic induction and the other in magnetic resonance. They are the two main technologies used in mobile devices at the moment and the Samsung has obtained the patent for a pad that can support both types of wireless charging.
At least that’s suggested in the schematics you see bellow. Though they applied for it back in March, USPTO just made the patent public and it is speculated that the new charging pad will be launch alongside Galaxy S9, which is supposed to be launched in Q1 2018.
