I am also pleased to report that the battery on my 2017 13" MBP TB (i5, 512, 16GB) is as advertised. I've had the machine for two weeks now, and I'm getting consistent times. Before buying I spent countless hours on this and other, similar forums, poring over the cryptic messages of extremely poor battery life (keyboard issues aside), and battling with myself whether to switch back to Windows after 13 years in the Appleland. I'm glad (so far) that I went with MBP, as this computer is a joy to use. My main tasks are writing (iA writer in fullscreen), SketchUp, and PDF databases (Sente, Mendeley), apart from the obvious Safari and Mail. I haven't really needed to go over 75% brightness yet, but this might change come summer sunshine. As of now I charge it overnight and take it without the cable for the entire day of work.
