No we are not. It does not matter what you install. The battery is smaller and the power consumption is still the same under moderate use --> less battery life. It is very simple.
It's not simple. I was losing 15-20% in 30 minutes. This is after migration. I then reinstalled 10.12.1 from scratch and I have long long battery life. Please don't try to state a fact that is not fixing anyone's issue. My solution actually fixed my issue and I want to pass it along.
I feel like there is something wrong with the migration assistant, pulling in old files that are possibly causing the Radeon to work all the time, dropping battery life like crazy. My mac was super hot before and now it's very cool, doing the same things.
The software is mostly to blame in the battery fiasco. Sierra is not helping (beta or not). Some people are having "real" problems probably due to one or more software processes.
Glad to hear your problems have been fixed!
Batter estimates are not accurate. Please read various posts with tips about:
- Sierra reinstall
- PRAM / SMC reset
- Safari vs chrome
- ad blocks (different software can yield lower/higher power usage)
Etc
In any event follow the first rule of battery operated hardware: fully charge overnight and give its first use until it runs all the way down the battery. Then plug it back again overnight for a full charge.
Well, if you read the last 5 pages you can see that I tried everything
I reinstalled everything, did every reset at my disposal, and its just worse.

Sorry to hear that. I've been reading for awhile but can't keep everyone straight. If you're running the factory Sierra from scratch and having abysmal battery life, return it. If I'm getting 10-12 hours of screen time with my migration (plus Sierra reinstall) then you should too unless your system has a problem.

How many times are people going to take their 'time remaining' estimates as gospel before they realise it's totally meaningless?
At least try using a full charge to see how long it actually lasts!

So i have not read all 44 pages.
I am scheduled to get the new 2799 model for 1999 (amazon price error) and i wondering how much worse is the battery compared to 2015 model?

A) Did you use Migration Assistant or is this stock?
B) If you did the above, have you tried reinstalling 10.12.1 from a USB thumb drive?

I ended up going with a 15" and I set it up as new and I'm getting decent battery life with web browsing and probably a little worse battery life than the 13" when I'm pushing it because of the GPU I guess. So what I would say when comparing the two is 13" was about 9 hours web and 6.5 hours when pushed. 15" seems to be about 10 hours web and 5 hours when pushed (though I imagine there are people pushing it harder than that). To me it seems like there is an issue when people migrate, I just set both machines up as new and turned off auto brightness put my display at about 75% and keyboard at about 50%.
My 13" started at about 6 hours web then I made those changes and it got to about 9 I made the changes immediately to the 15" and it was getting about 10 right off the bat. I did notice my 13" came with the keyboard backlight all the way up and I turned it down to about half to get to 9 hours and my 15" came at halfway out of the box. Not sure how big of a difference that would make just something I noticed.

I assume you're talking tb versions of both? Also, what made you go 15" out of curiosity? Congrats on your as-advertised battery life.
Yep I had TB versions of both and I'm really mainly using safari so maybe that's why. I also don't really have hubs or displays plugged into it and those are the numbers without the speakers but seem to be replicable with headphones. I was getting about 4-7 watts browsing on the 13" and about 7-10 watts browsing with the 15". If I start processing photos or anything that they both start eating through battery but I personally get about their usage for web.
I have been getting into photography recently and the screen on the 15" is just a lot better for going though images and it seems to be great for processing. The portability of it kind of surprised me, the 13" does seem like the perfect size for portability but with how sleek these are the 15" isn't that much worse to carry around, like I really don't notice that much of a difference honestly and the tradeoff is really worth it. I'd have no problem bringing the 15" out or using it while traveling so it's great for me.

After the current beta drained my 15' (standard config) by 10% every 15 minutes, another clean install (non-beta) did the trick. This time I left out Chrome and the entire Adobe CC stuff. And the battery is absolutely fine. Getting about 9-11 hours on almost max brightness, one bar below maximum. Doing some light MS Office stuff, Safari browsing, YouTube and Netflix.
About 1.5 hours mixing audio- but I mix heavy (15-30 tracks, 2-3 AAX each track, 7-10 VST's) and use a bus powered DAC (Groove).
3.5 hours watching Hulu/HBO.
5-6 hours connected to wifi with light browsing and using MS office programs.
9 hours wifi off, using MS Office and playing music through speakers or headphones.
FileVault was never activated, I didn't migrate, everything is updated. I often have several background things running when on wifi, (Avid Manager, gobbler, flux).
Edit: All seperate cycles. 15" 2.9/460/1tb.

I get similar watts on my 13, I think that's what Apple had in mind. Your 15" watts seem appropriate for the bigger battery and faster processors. I can imagine that the 15 would be nice for mobile screen real estate. Honestly, going 15 never crossed my mind. I've always used 13's exclusively, and they fit the laptop definition for me, especially since I am usually attached to a monitor. Enjoy your sweet MBP.
In a lot of ways I agree the 13 just seems like the perfect size for a laptop which is why I really thought about it. If it was any other generation I may have gone that way too. The 13 was really great to use the combination of power and size is really amazing. I feel that way with either really they both just pack a hell of a lot into a small package. If it wasn't for the photography and how much easier it made comparing images I may have stuck with it. Thanks and enjoy the 13 those are really beautiful machines.
Excellent! Glad this solution worked for you as it did for me
I did it too. And it did NOT work for me. 6-7 hours with only webbrowsing. Spotlight disabled. Siri disabled. Only browsing on sites like macrumors.com without flash, without any plugins. 6-7 hours.
