Children don't really have property rights, and even if they did, courts have consistently ruled that the bill of rights is reduced in school settings.

Courts have ruled that there are specific interests in school that meet the generally applicable (not special, weaker) standards applicable for permissible action where rights protected in the Bill of Rights are involved.
But establishing categories of and confiscating contraband is... not a disputed state power, in any case.
Children don't have property rights but their parents do and they own their children's things. If a parent went to the school and asked for the confiscated item that school would be insane to deny them.
They'd be insane to deny them because disgruntled parents can cause an incredible amount of trouble for schools, not because confiscating the phone when established by clearly communicated policy is actually meaningfully illegal.
Children own their stuff. Parents can control the child’s things like they control other aspects of child’s life. They give some of the control to schools.
What happens when child becomes an adult? They own all their stuff from before, the parents do not keep it. It can be complicated since parents let child use stuff, but anything given to or bought by the child is theirs.

I think that parents basically "gift" their adult children their old things. At 17 years and 364 days a parent can take everything their child "owns" and burn it/throw it in a wood chipper with zero legal issues (concerning specifically the destruction of property anyway, burning/chipping some things will get you in trouble), however once the adult child has been informally gifted their old "belongings" there's no take backs without legal repercussions.
Things do get more complicated with things the child bought with their own money... I'm guessing the law would be more willing to accept that those things should belong to the child, but even if a 15 year old kid buys an xbox with their own money I doubt the cops would arrest the kid's parents for smashing it with a bat.
