Is anything showing on the screen when it's in a charging cradle? It's never fun, but sometimes electronics just fail and die, especially these tiny ones with tiny batteries. In my personal experience, fitness bands (and not just Samsung), only last around a year, a year and a half. If there is no warranty, there is a new model out now, Galaxy Fit2. I tried it, it's not bad at all. Larger screen, better battery life. And it's only $60. Might be worth checking out!
