Your phone shouldn’t be the first or last thing you look at in a day.
With that, don’t sleep with your phone in the same room.
Remember why the phone was created: to communicate with other people.
For that reason, don’t have it out when you are interacting with people in person. Don’t have it out on a date or at any meal with others.
It is a tool not a toy. You do not need a new phone until yours no longer works.
Minimize your device usage.
Face time > screen time.
