I was violently assaulted by my boyfriend. What happens now?

Two nights ago, my 22 year old boyfriend, in a fit of drunken rage, violently assaulted me for 10 minutes. (Without going into too much detail) two security guards saw the attack from our apartment window and called the police. He spent the night in the drunk tank and now has a court date for August 3rd. I’ve never been in this kind of position and have no idea what’s going to happen to him. Is it likely he will be sentenced to jail time? I believe he’s been charged with battery. Please weigh in with your experience with this subject if you have any.
