ProTip: Never allow work email or chat systems on your personal mobile devices. You won’t get sucked into ultimately non urgent work things if someone has to actually page or call you during out of office hours. That small barrier is all that’s needed.
Also, leave your company provided devices at the office or turned off when not on active call rotation. Make them work a little at contacting you for an emergencayyyyyy.
This has served me well, except I still fall into the trap of looking at mail/chat via web browser now and then.
