Kind of. But you can see boredom as the desire for novelty, a cue to find something new so we can get that dopamine hit. Phones, internet and media are fantastic at giving us that little kick to keep us going, so we don't feel the need to engage our brain in more useful ways. Without that easy access to the dopamine treadmill that is your phone, you are encouraged to seek novelty elsewhere. This might be in wandering thoughts, seeking interaction with people or things around you, or some other endeavor.

To think a little further forward, doing this tends to increase the time until the next novelty, so you get practiced in not constantly seeking immediate gratification. It helps increase your ability to be patient and to concentrate, which in part is the ability to not switch tasks at the first hint of boredom.
