I am ready to quit my phone.

My motivation is to improve my effectiveness in, and enjoyment of, life.

I am confident it will be net beneficial to remove my phone as the crutch to which I default my attention in lieu of anything else occupying it in a given moment.

PHONE RULES:

I think I may have already found solutions to 3 of the 4 walking exceptions below. I traded in my old Apple Watch SE for an Ultra 2 which I expect will double or triple the battery life. While I often take walks with more than 90 minutes of combined calls and dictations, I pretty much never go over 3 hours without stopping home for a break. So I may not need to take my phone for long walk and talks anymore  (3b and 3c), but I still need to test it.

That sounds like a smart solution! Testing it out will give you a clear idea of whether it meets your needs. Good luck with your walks and talks without needing to carry your phone!
