I also observed that my own smartphone usage is unhealthy - constantly checking it when I am taking a walk, or when I go into a park to lay in the sun, or read a book etc. I never could go long without checking my phone, engaging in Whatsapp or looking up something on the web. Even so when on an activity I specifically picked to be offline/away from my computer. My solution was also getting a dumb Nokia phone as a "leisure phone", which has no WiFi/BT but a headphone jack and music capability (it has an ancient Opera browser that I never use). Luckily my phone provider offers a "dual sim" service where I get a second SIM card with the same number, so in case someone calls me, both my iPhone and my dumb phone ring simultaneously. I only programmed a number of ~10 close friends and family into the phonebook, and now when I leave the house when I want to have some quiet time, I only take the dumb phone. I have the security of being able to call for help in case of emergencies, and am reachable for friends and family in matters of true emergencies (calls, not Whatsapps). Battery lasts 3 weeks in standby, but since I mostly have it turned off and turn it only on when I take it, it becomes mostly irrelevant. Unfortunately the dumb phone selection isn't perfect; I'd really like to have a better camera because I do want to take snapshots now and then (without the urge to immediately upload it to social media) and the music player is very limited in functionality. As for the experience, I can highly recommend this. Ever since I got it and got into occasional "offline mode", I realize how much BS time I spent on the smartphone. Having those "off" times are relaxing and bring a certain peace of mind. And funily when I am out without the smartphone, you realize how much other people are constantly staring into their phones in locations they actively went to refuel (parks, lakes, beaches, at the movies etc.).
