Well, it depends on the type of teacher. If it's a strict one, Percy might be sent to the principal's office. But if it's a more lenient teacher, he could just get a warning. Also, the reaction of his classmates would be interesting. Some might laugh, while others might be annoyed that their class was disrupted.

He could introduce some new combat styles to the Dueling Club. His experience in fighting monsters as a demigod would give him an edge. He might be a bit of an enigma to the Hogwarts professors too. They would be intrigued by his different kind of magic. And with his being betrayed, he could be a bit guarded at first, but gradually open up as he realizes that not everyone at Hogwarts is like those who betrayed him. He could also discover some hidden chambers or secrets in Hogwarts that have a connection to his demigod world, like a hidden place that has a link to the Greek gods.
I think Percy's classmates could be quite affected too. Their concentration gets broken, and if they were in the middle of an important lesson or test, it could really annoy them. Some might also be worried that the teacher will be in a bad mood for the rest of the class because of Percy's phone, which could affect how the teacher interacts with them for the remainder of the period.
Perhaps Percy would use his knowledge of Greek gods and goddesses to impress the teacher. He could share some unique insights about a particular deity that are not commonly known. This could lead to him getting special privileges in the class, like being excused from a difficult assignment or getting extra credit.
One possibility is that Percy clashes with the school's jocks or popular kids. Since he's an outsider, they might pick on him at first. But then Percy shows them what he's made of, not with brute strength necessarily but with his quick thinking and his ability to outwit them. He could also get involved in a school competition, using his unique skills to help his team win.
He could be using his phone to track a villain's movements. Maybe he installed some special app on his phone that can detect unusual energy signatures. So while the teacher is droning on about history or math, Peter is secretly following the path of a super - villain who is on the loose in the city.
In the 'Percy goes to Hogwarts alone fanfiction', it's possible that Percy will discover new aspects of himself. Since he's alone, he has to rely solely on his own wits and skills. He could stumble upon some hidden secrets of Hogwarts that others haven't found. Also, he may have some unique encounters with the Hogwarts professors who take notice of his solitary situation and offer him special guidance or tasks.

For example, he could join forces with Thrall and help him in his quest for the Horde. His sword - fighting skills from Camp Half - Blood would come in handy in battles against the Burning Legion or other enemies.
