Smartphones don't just reduce your IQ; if you use one while walking, it removes all your situational awareness. I constantly have to step out of the way of some zombie walking along the footway, oblivious to the existence of other pedestrians.
My smartphone stays at home, on permanent charge (the battery life is severely depleted). I use it only to collect SMS 2FA codes from those organizations that assume that everyone has a smartphone. We call them "mobile phones", but that doesn't mean you have to move if you're using one.
That zombie effect applies equally if you're behind the wheel of a vehicle. Please don't ever do that. Of all tasks, driving is the task that requires the greatest situational awareness.
