Just use your phone. If the temptations of checking your phone are that high that it’s affecting your life than I’m willing to wager their are other issues, too
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].
