Might I suggest it's not the phone?
It's the communication and dopamine hits you get from that phone you struggle with.
And I am saying that because you are very likely to move those to whatever else you use, which does you no real service.
What you need to do is have some boundaries. Once you've set a few, you can then evaluate what is worth what with some better perspective and that dopamine will have less value and other things in your life will have more.
