Hi there guys. Just got my maxed out MBP 15'' (2.9 GHz i7/16 GB/512 GB/AMD 460) 3 days ago. It is really good after the 2013 13'' MBP with the lowest configuration possible, I am really happy with it except one thing: battery life sucks. I got macOS Sierra 10.12.2 with it and the battery life was a joke: I don't do much right now, mostly just surfing web and watching Youtube videos (720p) and I got about 4 hours. I read some threads here in which people said that 10.12.3 beta 4 improves battery draining issue by a lot but it doesn't seem to do it for me. Unfortunately I don't have any battery details from 10.12.2 but right now laptop uses 13.5-14.0 Watt while I am writing this text in Safari. Other apps that are running in the background: iTunes (no music turned on), Clear, Evernote, Skype, Dropbox, Airmail 3 and Telegram. I attached couple of screen shots from the Battery Health 2 app. Do you think there is something I can do about the battery? Like clean OS installation or something like that? Or do i go directly to the Apple Store and get an exchange? Because 5H with Safari is just a joke. I got about 10 hours by doing all kinds of things with 2013 13'' MBP.
