Not only will phrasal verbs make you sound more natural, but they can also help you avoid making mistakes. For instance, a very common error is the misuse of the verb update when talking about news and current affairs:
I try to update about the news by reading articles online
I watch the news to update me on what’s going on around the world

I try to keep up with the news by reading articles online
I watch the news to keep up with what’s going on around the world
