To be quite honest, I have a feature phone, in part because I think smart phones affect most people's lives, but I'm willing to accept that as my personal issue.

Setting that aside, I also don't like the large size of smart phones, the relatively short battery life, and the poor durability.

I don't have specific references on hand, but I'm pretty sure that your wager would be ill-begotten. Studies have shown that simply abstaining from distraction takes mental energy (for lack of a better term) and reduces performance in a number of ways. This suggest that designing your environment ahead of time (what OP is trying to do) is more efficient/productive than resolving to maintain disciple in the moment. Again, I don't have specific references on hand, but I know that this phenomenon is discussed in both Thinking Fast and Slow[1] and the Craving Mind[2].
