More screens with less content or less screens with more content

Well my problem seems very common but i was not able to find any solution or research about it. The problem is i am working on an app that has lot of information to show and also has lot of actions that can be taken on that information. As per Hick's law the less choices per page the less the friction, so i divided the content dividing all the actions to many screens. Which created some flows that go too deep. Which my boss says is not good, having everything in one place is better. So what do you guys think is the best thing to do and how can i prove it to him.
