The battery life I was talking about was only on my Series 3.
Also, when Watch OS 5 released, they FINALLY fixed the issue of not getting workout credit when using the Outdoor Walk workout. Turns out, Apple didn't like that being fixed and reverted it right back in the most recent update, citing "some users getting higher workout minutes than they should"... NO, assholes, it was finally working properly, and now it's not again.
