The battery won't last long if you talk a lot on it and use watch over cellular connection all the time. 570mah battery can only last that long compared to normal phone that typically is 2000mah and up.
Also, if you use GPS for long run tacking, watch battery runs down fast. The numbers I saw others posted is like around 3.5 hour max.
