I love Notification Center in iOS 5. I love not missing any notifications because a new one came in. And I love periodically pulling down to open Notification Center just for the sake of opening it (I love me some touchscreen gestures, too).
I don’t love that my iPhone goes off at all hours of the night. When I go to sleep, I toggle silent mode on. While I don’t hear notification sounds during the night, because I have my iPhone set to vibrate while on silent mode, it still vibrates at all hours of the night.
Missing from Notification Center is a sleep option where you specify a block of time where the notifications will still roll in, but iPhone won’t make any sounds. Some apps like Tweetbot and Boxcar have this option in their settings, but not all apps do and certainly not the Apple apps.
So here’s what I do: When I go to bed, I toggle my iPhone to silent mode like usual, and in the Sounds settings, I turn off vibrate in silent mode
Notifications will still accumulate, but my iPhone won’t make a sound and won’t vibrate all through the night.
If I am using my iPhone as an alarm, the alarm will still play its sound even when the phone is in silent mode (this works for the Clock app but not for third-party alarm apps).
Having an actual sleep option for Notification Center would be great in a future iOS release. Until then, this is my workaround. Maybe you’ll find it useful, too.
