Microsoft reboots war on sleep
Way back nearly two decades ago, I set up an early version of ActiveSync on my Palm Treo device.  I noticed there was an option in the Treo email settings to disable real time syncing between certain times (after office hours), but I was SO excited about getting and responding to real time emails on my little phone device that I thought "Who the HECK would want to stop this wonderful flow of emails".Later when I upgraded to the first gen iPhones, I noticed that they didn't have the option to turn off ActiveSync at all.  I thought it was odd, but I still didn't mind.Nowadays, I often leave my phone on DND or Airplane mode for large chunks of the day.  I am totally sick of the deluge of mail from what is now 6 separate email addresses.  I note that iOS 10 still hasn't got the ability to turn off syncing between certain hours that I know of.  On top of that, I have alerts constantly popping up from Twitter, Slack, HelpScout, Intercom et al.I think the whole "Work can wait" movement is a good one that needs to be front and center at a lot of workplaces (and a lot of apps).EDIT: Thanks to the responses below, I now realise that iOS 10 DOES indeed have the capability to turn on DND during certain hours only! Winning.
