I used to keep work email and calendar on my personal phone. A few years later, I disabled the email because it distracted from life. I leave the calendar simply to let me know when I have an early meeting (my day normally begins at 9, but work with teams in India, so occasionally have earlier meetings).
Anyways, that is just backstory to say, getting rid of my phone was the best thing I ever did, I have a burner with a few hundred minutes on it, in my truck for emergencies but I honestly never use it.
A good deal of people could actually untethered themselves from their phone dependency and actually find out that they enjoy it a lot more than being leashed to one.
