Rumors for the Galaxy S IV are running rampant since a few months as we come ever so close to it launch. According to DDaily a Korean Media site, the S IV would have a back cover which would support wireless charging. As we have already seen with the wireless dock for the Samsung Galaxy S III.
Now according to sources, Samsung are working on a new technology for wireless charging called resonant magnetic coupling. It basically means that the phone will not be required to be placed on the wireless cradle. The charging radius of the dock would be around 2 meters, so you can take the phone around your house while it charges at the same time.
The Samsung Galaxy S4 if rumors are true then would feature an Exynos 5 Octa (8-Core) CPU, Mali-T658 (8-Core) GPU, 4.99″ SuperAMOLED Full HD Resolution Display, 2GB of RAM, 13 Megapixel Rear facing Camera capable of shooting 1080p Full HD Videos at 30FPS, 2 Megapixel front facing camera capable of shooting 720p HD Videos and run Android 4.2.1 Jelly Bean directly from the retail box.
We might get a glimpse of the phone before the MWC in Barcelona, will have to just wait and see what the future has in-store for us.
