Well it depends honestly before going to bed I put my phone into kitchensafe box and set the time for atleast 2hrs so I can fall asleep without looking at my phone.
During the day if I’m working I’ll put my phone into kitchensafe for like 30 or 45mins so I can focus on the task without looking at my phone.
As far as calls are concerned if they are important they’ll probably leave voicemail and I’ll get back to them right away
Lastly I usually keep my phone locked at night before going to bed as It helps me stay away from it
