Samsung Patent Shows a Dual Device Charging Pad for both Magnetic Induction and Resonance Charging Methods
There’s been a trend of smartphone OEMs using glass for the back of their device and this means OEMs can painlessly incorporate wireless charging into their premium designs Qi wireless charging is the most popular standard and it works in both inductive and resonant modes of charging modes. To leverage this, Samsung filed for a patent back in March of this year that shows they could be releasing a charging pad with charging coils working in both modes as well.
There are a number of materials that an OEM can choose when building the outside of a smartphone. Years back, most devices on the market were made of plastic since it was less expensive and it was generally more durable since the plastic can flex to take the pressure off the important components. Some OEMs shifted to metal build materials while others opted for glass. Sadly, wireless charging can’t pass through metal right now so many devices like the Pixel 2 and the Pixel 2 XL are left without.
Samsung, however, has been going all in on the proverbial glass sandwich builds where the front and back of the device use glass that is held together with a metal frame around the sides. Similar to Apple’s new iPhones (that finally use wireless charging), Samsung has had wireless charging in their devices since they switched to this new hardware design. Qi wireless charging is the most popular standard and it works in both inductive and resonant modes of charging.

That is what makes the new Samsung patent unique is uses two magnetic induction coils and a single resonance coil. As with all patents, it’s unclear if the device illustrated in the photos will make it to the market. With Apple utilizing wireless charging though, and offering their own multi-device charging pad in the future, this design should enable Samsung offer their own competing solution for their own Galaxy S, Note and Gear devices.
