Wireless charging is hugely convenient and is perfectly executed in the Lumia 920. You get home, drop your device on the Qi-compatible pad, and that's it. It's simple to the point where you don't even need to think. That technology is reportedly on its way to the Samsung Galaxy IV, a new FCC filing suggests.

Images show a Samsung-made charging station, with a Galaxy S III sitting peacefully atop the unannounced accessory. There are currently no Samsung devices that support Qi technology (unless you use a third-party option), so it's not outside the realm of possibility to expect the S IV—or even the Galaxy Note III—to arrive with built-in support.

There have been rumors pointing to a March announcement for the S IV, so the timing of the FCC filing is quite interesting. Wireless charging hasn't exactly become a "thing" among consumers, but an appearance in the S IV could help to change that in a big way.
