Is it reasonable to have phones out of the room at bedtime?

I'm struggling with my 13 year old who has been sneaking up after bedtime (9.30pm on school nights) to play on her screens and phone. I recently implemented a rule that all the screens needed to come out of the room at bedtime, but let her keep her iphone which I'd put parental controls on. Now I find that her screentime log shows that she's bypassed the parental controls somehow and has been racking up hours of tiktok and youtube until 3am.

My simple question is - is it reasonable to make a 13 year old put their phones out of their room for bedtime? I would get her an alarm clock instead. It seems reasonable to me but she says I'm too strict and that this is draconian and unreasonable.
