I'm confused:
# Builds completed Total battery life Avg. Build time
2016 Touch Bar - 3.1 GHz i5 49 4:54:00 0:08:45
2016 Fn key - 2.4 GHz i7 30 3:54:00 0:07:52
2015 Retina - 3.1 GHz i7 24 3:30:00 0:06:02
suggests that the 2016 model did 19 more builds, and had a battery life of 1 hour longer, suggesting a _better_ battery life...
