If not known already, I noticed that battery life varies a lot depending on the watch face you are using. The simple watch face uses approximately half the battery than the activity one. I have tested this for a few days to exclude other factors. I'm still on 80% for my Series 1 model with 2 hours of usage and 10 hours of standby. Like it!
