> I don't see why you are defining success as 30 days of battery life when the baseline is charging your watch every day.

Up until about 10 years ago, no one would have considered the baseline to be charging your watch every day. Even today, most watches/wrist-worn step counters don't require daily charging.

I wouldn't define 30 days as success, but I do want to start out at 2+ weeks. Battery life gets worse over time, and watches aren't meant to last for just a little while. I don't want to spend hundreds of dollars on something that will require charging more than once a week within a year or two.

Appreciate the links, but I'm guessing these are estimates with AOD disabled? That's another benefit of the Pebble (AOD doesn't reduce battery life).
