That's correct, I am working in mobile world since 2005 and the latency of mobile networks is the most bad thing when you build mobile apps. The more requests you do the more latency you introduce to the user, especially if it's fetching data for UI, even if you do it asynchronously you have to wait for the data to update the UI.
