I put my phone on airplane mode as I left to go to the lab today; took it out of airplane mode three and a half hours later and my phone didn't stop buzzing for 30 seconds as the notifications came in.
I turned off all sound and buzzing on my phone before a date like five years ago. I only turn it back on when I'm waiting for a pizza to be delivered. I love how my phone doesn't not distract me unless I decide to look at it.
In January I bought a fitness watch. It has some smart functions, including displaying phone notifications. I've decided it's the right level of distraction. I can glance briefly without digging around in my pocket and know it's something I want to look at or want to ignore.
When I hike I'm sometimes out of cell phone range. It's great. It isn't like I'm staring at my phone in the woods, anyway, but it wipes out any temptation.
