Personally I believe this sort of post is lacking real data: true the mentioned user only has 6 tabs in Safari, but what about other apps? How many other apps are running at the background?
I mentioned those because last week I forgot my charger(I'm using a i7 version of 2016 13' Macbook Pro with touchbar) at a friend's place, and by closing a few extra apps that I rarely used, I could get close to 8 hours' time developing a web application. I didn't dry out the battery so not sure the maximum time it can hold.
That's not saying this laptop is perfect, at the moment it did suffer from a few quirks, and personally I don't like the keyboard, but my point is: posts like this about the battery is not so accurate.
