Samsung have invested in the New Zealand-based PowerbyProxi to explore how to introduce the long-distance wireless charging in their upcoming device.
Magnetic resonance wireless charging is unlike the current wireless charging used by Nokia and LG - which requires the handset to be placed on a plate - resonance wireless charging would allow you to charge your handset without the need for it to touch a charging pad, at a distance and through solid, non-metal objects like wood. So you would be able to charge your phone while using it normally.
This new technology is expected to be available as early as mid 2014, and probably will be introduced with Galaxy Note 4.
Will we see this dream come true; this will be a great and useful feature.
