When she is calm, remind her that your actions were absolutely fair in that you set a rule and a clear consequence and she is responsible for choosing to break the rule, not you. Then have a conversation with her about what was really underlying this. I'd suspect that she has some insecurities about her status in her group of friends and that this was fueling her actions. Try to get her to identify what was going on. Then i would tell her that you see she is clearly developing an unhealthy dependence on her phone, as evidenced by the fact she can't be without it for a day, and that you will be instituting additional phone free hours until she proves she can better self regulate.
All of this interference will just cause her to really want to punch you in the face. Rightly so.
Read all of this again and then imagine that someone is speaking to you this way and treating you this way.
