I transitioned to a feature phone from an iPhone to improve my overall well-being. The pros and cons list laid out above may be food for thought for those on the fence. Others may empathize with the approach of altogether abandoning rather than practicing self-restraint on a device ingeniously engineered to drain your attention.
I tried doing that too, but to no effect. Ultimately, I feel that I lack your level of self-discipline when it comes to owning a smartphone. Therefore, in order to deal with perhaps my biggest source of distraction, and a large source of anxiety, I decided to ditch it altogether.
