If that's really the reason, then that's pretty much a failure. According to ars' synthetic battery life test, the Moto 360 is the worse. It has a slightly bigger battery than the Samsung, and has only 56% of its battery life.
PS: it's not only in ars' synthetic test but also real life reviews said the battery life is too low.
