Wow, that's a great analysis. In addition to being less efficient, there's definitely more overhead with the extra layer of JS underneath. Just of the top of my head, this might be a bigger issue with apps that constantly refresh the screen or have real-time interactions (e.g. games or Slack), and not so much apps that are essentially a series of forms (code only runs when you interact). With our app, what affects battery usage most is the location analysis that happens in the background. It's one of the areas the development team spends a lot of time testing and optimizing.
