My personal experience on this is like the article above states, merely having my phone on hand caused me to think about pulling it out or looking at it even if it was turned off. It was not till I hid my phone away in my glove box or somewhere I rarely accessed did I feel truly free from it. I will say having done this for months now I really don't miss it and only go grab it when I absolutely need it (usually for work stuff). The result is that I feel much less distracted and more focused on my life as it happens, also my view of the world seem more grounded in reality now.
