A lot of people, like me, sleep with the phone right next to their beds. I use mine as an alarm clock as well. Having it light up at all could be distracting to some, even when dim for those light sleepers. Also, silent mode can interfere with certain apps, like an alarm clock app if you are not using the built-in one (I don't, I hate it).
I use mine this way as well and can see the above being helpful. However, I don't have an issue with alerts, SMS or calls coming in during the middle of the night. I also insure my alarms or notifications in Outlook aren't set to ding during that time.
Having your phone on Airplane mode does have a flaw when you turn the mode back off. You won't get notified of missed calls, only the voicemails associated with them if the person left one.
IMO if I miss a call and there's no voice mail, it wasn't an urgent call thus I never worry about it. If it's not important enough for me to have a message then I see no need to see if it was just missed. Especially during a time where I was busy enough to block out other things.
And, your phone will be temporarily bogged down as message after message and VM after VM come streaming in and your phone will be going off with notification alerts for the next 20-30 minutes. That can get annoying.
Is that really likely? I mean, if you're getting VM after VM streaming in simply from not being available for a certain period of time, then there are other issues in that work/personal life that need addressed. I guess I just don't see that. During a busy afternoon of meetings I might get 2-3 maybe even four missed calls but during the day at meetings I will just put the phone in silent mode. At night, I can't see the above being applicable.
Look at Do Not Disturb as a more customizable version of silent mode, allowing very important people of your choosing to get thru in the event of an emergency, like your son or daughter out with friends that night.
Again, I can see this example but then as noted above, I think it's subset of users that folks are likely getting woken up at night by their phone. Useful feature to them I suppose.
And it has that feature, when enabled, that if the person calling you tries calling back within 3 minutes, it'll go thru like normal. It just gives you more options to help you get some sleep, yet get notified when it matters.
at first it sounds like a good feature, but in my case it would be annoying. When away from my office I push call forward on my land line so it hits my cell. Often times people will try me there first then at my cell number in which case, I wouldn't want a repeat call within 3 minutes coming through.
Not knocking the feature completely. I like their interest in giving folks more options for things like this. Just seems to be a feature at a more targeted subset of users. Or maybe I'm the odd one out.
