Yeah, having both a new gen Surface book and a new MBP, the difference is stark for CPU and I/O intensive tasks. With battery saver on, the Surface Book can easily last 6-8 hours of use.
To get that far with my MBP I'd need to essentially disable the screen, disable all backgrounding, turn off incremental compiles, and try to be careful about using my clojure repl. You immediately stop using Chrome (despite being a better overall browser) and go to the inferior Safari for battery life, etc.
The tradeoff is that the MBP compiles about 10-15% faster, but as it only lives about 1/2-2/3 as long on a single charge it is not worth it to me.
