Battery life smart watch

Hi, I was wondering if you have a 50 days battery life in smartcwatch as it is advertised by Garmin?

I seem loose 3% ish per day

I seems like loosing 3% to 4%, which won't last for 50 days. 

  • stock digital watchface with seconds
  • all sensors except pulse ox
  • 20% light without move detection
  • phone notifications

At this rate won't go for 50 days, even if would still be solid battery life.

Just checking because my instinct solar was very accurate on its 24 days.

Thanks :)
