I am a runner and usually exercise 60-90 minutes a day (includes my runs). I don't use gps much if at all bc if I am running outside, I always have my phone with me.
So for example, I've been off charger since 5am and am 13.5 hours later, I'm at 56%. By the time I go to bed tonight, I'll be below 50%. I can't make it through 2 whole days. S2 is def better than S0 though.
Oh I have a 38mm watch.
