I find all notifications and badges disturbing which is why I turn all of them off on my iPhone except for phone calls/text messages from my family, alarms I set, and calendar appointments. Nothing else is so important that it needs to interrupt my work or peace of mind.<p>I realize that many company cultures won't allow this. But it is a huge boon to productivity and peace of mind.<p>I check my apps when I want to check them, not when the apps or other people want me to check them.
As someone that manages a large distributed team all over the world I really like these kind of features. I don't feel the need to totally disconnect from work every night. But I've also been known to leave my phone while on vacations for real disconnects a few times a year.
I'm glad I'm not anymore in a workplace with Slack (or any kind of instant messages) and there's not expectations of being available to answer messages outside of office hours.
