If your work-style is butt-in-seat for 8 hours having everything on your laptop probably works. For folks with a more meeting-heavy workload, having at least your work calendar/email/messenger on your phone is pretty hard to go without
Why are you on your phone during meetings and not paying attention to the meeting? We ban phones/laptops for the specific reason of people attending and not paying attention.
My question, why do you need them on your phone during work hours? Why aren't you using a desktop/laptop/something else?
