Can anybody tell me what screen brightness Apple used to get their 10hr life expectancy for the new MacBooks? I suspect that this is one of the biggest factors in battery life and unfortunately I like to run my display brighter. I suspect they used 65-75%

Can't answer your question directly, but bear in mind these displays go much brighter now, so the 65% of a 2016 is much brighter than 65% of a 2015 as a result. So you may not need to run it at 90%+ to get your satisfactory level of brightness.

The exact details of their test scenario are outlined at the bottom of the page of tech specs in the fine print. "The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%." http://www.apple.com/macbook-pro/specs/

What @geachy92 says is absolutely true though. These new displays are insanely bright compared to the previous ones or most anything else on the market so you should be able to get away with a much lower setting.

I keep my display and low as possible, and that does help a lot
 
Yep, and further to the above, Apple's battery life estimates are very conservative. On a Windows laptop, "up to 5 hours" means "4 hours 59 minutes on lowest brightness and Power Saver plan".

There were people getting 16+ hours from their MBA when Apple quoted 12 hours. So I wouldn't worry that much about burning through the battery. You'll still get decent time when it's very bright.

Great! Thanks for the info :) look like the reduced battery capacity doesn't impact too much on the life
