Changed study techniques for improved learning?

I'm sure this question has been asked before, so if you recall the thread, please post it in your comment.

Have any of you tried changing how you study or learn in order to learn material faster, better, or more efficiently? Did you see major improvements? Did you stick with it after?

Here are some examples: In the past you studied 4 hours straight with no breaks. You later started studying in 20 minute chunks with small breaks in between. You noticed that you picked up information faster and learned better.

In the past you studied at your home office or coffee shop. Now you study at the park or beach. You've found that you're more focused and refreshed, and therefore pick up information faster.

I know there's a lot of research into study techniques and how we learn, and also that everyone is different. I'm curious if any of you have tried new techniques and if they worked.

Thanks!
