Samsung Galaxy S IV rumored to support wireless charging, dock to be sold separately
No, the Samsung Galaxy S IV won't have a built-in laser hologram projector, nor a glasses-free 3D screen, nor an AMOLED display of the bendable kind. What the company's next flagship is a lot more likely to offer, on the other hand, is wireless charging, and Korean media DDaily is claiming that the yet-to-be-announced device will indeed support the Qi standard. Samsung will allegedly offer a module made specifically for the purpose, but will be selling it separately. The back plate containing all the necessary circuitry won't be bundled either.
It is also being said that Samsung considered using an alternative, more advanced wireless charging technology known as resonant magnetic coupling. That, in theory, would allow the Samsung Galaxy S IV to be charged from a distance of up to 2 meters. In comparison, the few smartphones that are available right now with wireless charging support require to be placed at a distance of no more than 4 centimeters away from a charging pad. Yet ultimately, Samsung gave up on the idea of using resonant magnetic coupling technology for it being too difficult to bring to market at a reasonable price.
If rumors are to be trusted, the Samsung Galaxy S IV is to be announced within a few months, with an appearance at MWC next month still not being out of the question. However, the smartphone isn't likely to be commercially available earlier than May, 2013.
