Two weeks ago I bought a S4 and got 30-36 hours of battery with 30-45 minutes of training. I decided to change the clock for a Nike S4 someone I had Nike S2 and like their bands and faces more. But I now only get 15 hours without battery without training. Why does Nike S4 clear so fast? Should I replace and return to a standard S4?
