I don't lie about battery life numbers. People like to say, "I get 9 hours of battery life." when they mean that they get 9 hours if they do doing nothing but let their computer idle with the brightness at minimum. 4 hours with a 55Wh battery is an average consumption of 13 watts. That's because my typical workflow involves running a VM containing cassandra & postrgres (among other services) and recompiling go and javascript. My coworkers with 15" MacBook Pros tend to worry more about battery life than I do.
My fan comment was a joke about Slack's efficiency. Of course compiling a bunch of go code will make the fan turn on. That will use up 100% of your cores on any decent sized project.
