So it made it past the 3 week mark with about 10% left. Instead of letting it run down, I recharged it as I'm satisfied with the battery performance and don't have to worry about charging it every day or even every week.
The notifications on my wrist is very convenient, especially during meetings and while driving. Other than that, the only other thing I use it for is the Steps monitor. In an effort to be less husky, I'm trying to be more active and walk more, It reminds me when I've been sitting around too long so it helps in that regard.
I hope a future update allows me to respond to text notifications with an Ok, Yes, No or I'm Busy.
