I and most of my acquaintances no longer have a traditional landline phone. My smartphone is the only way to contact me in an emergency. If friends or family need to reach me to extricate them from a bad situation or come to the hospital, etc., I want to be reachable. It&#x27;s only happened a few times in my life, thankfully, but I don&#x27;t like the idea of being completely unreachable until I wake up and turn my phone back on.<p>That said, I could turn off wifi and cellular data, but that&#x27;s one more thing to remember to do every night. I suppose if you find the temptation overwhelming, it could be worth it though.<p>My point is just that turning off the phone is not as simple of a decision as you make it sound.
