Samsung Galaxy S6: You May Be Able to Charge It Anywhere

— -- Samsung is showing off its advances in wireless charging, weeks before the company is set to reveal "what's next" at the Mobile World Congress in Barcelona.

The electronics company hasn't revealed what is on the agenda, but the invitation included a shadowy profile shot of what appeared to be a curvy device -- sparking the possibility that Samsung could unveil its Galaxy S6 smartphone with a design change on March 1.
