It's a real test result. It's just that the test setup is not indicative of real life. Brightness is set to 100 nits. That's very, very low, at about 20% of the maximum brightness of the new MBP. I use mine at at least 75% when I'm on the road. The workload is simple. Consumer Reports says they have turned off caching in Safari (from the Develop menu), in an effort to simulate "real-life" browsing, but that's just not a very good way to simulate a real-life browsing workload. Fetching pages from a server is mostly waiting for the network, using very little CPU. If anything, turning off caching might give you better battery life in a test like this. Also, who knows how much the browser is caching data internally. It may fetch pages from the web (using no CPU, mostly waiting), but may still internally reuse cached, optimized versions from the previous page views. Also, I'm sure they don't have any background processes running, such as Time Machine (or other backups like Backblaze or Crashplan), Dropbox, Google Drive, playing music, Bluetooth headphones, etc. I'd be willing to bet that the Touch Bar is turned off during this test, too, which it wouldn't be in real life if there is real keyboard input. Finally, to be honest… just yesterday, I spent over 9 hours total developing a Django web app on the new MBPtb without recharging. I had plenty of opportunities to plug in, but chose not to, to see how far I can go without power. Also, I had brightness set so about 30-40%; less than what I would like normally. Anyway, I'm very happy with the battery life.
