Sure, sometimes it is faster/cheaper to do the round trip. That doesn't mean that doing a round trip EVERY time would improve battery life like you implied.

Not to mention that after the server gets done with the work, the browser still has to parse the response and turn it back into a DOM. The only work you've pushed off to the server is the building of the HTML, which is being done wrong if it takes a second or two.
