As for battery life, despite the difference in specs, Apple claims the same 10 hours for all the new MacBook Pros. So far that's matched my usage. I was juggling the three at a time to get this review done, though, so that's nothing approaching a normal pattern.
I normally do some things on iPhone, iPad Pro, and iMac as well, so I never spend all day with my MacBook. Still, I charged it to 80% the first week, went to the coffee shop, worked for 4 hours, and it ended up at just under 40% with the non-Touch Bar version. With the 15-inch Touch Bar, I worked for a few hours and, surprisingly, was told I still had 11 hours left (I'm chalking that up to how hard it is to properly predict future usage.)
I work in Final Cut Pro X and not Premiere, though, and use Safari and not Chrome, and I have a feeling that saves me significant burn. Still, editing video and keeping multiple tabs open is harder on the charge than typing text, checking email, and surfing the web. So, a pro machine has to bring it.
I'll keep testing and keep updating over the next few weeks.
