Stupid Phone Tricks

You could probably tag this "RTFM," but I just learned that my phone's alarm will go off -- sound and all -- when it's turned off. There doesn't seem to be a profile that silences the alarm, either.

Probably depends on the phone, but it's easy to try: set an alarm for five minutes away, turn the phone off, and wait.

Worth knowing if the battery's going low and you want to keep it off, or if you're somewhere that you don't even want an alarm sounding.

When the alarm sounds, it even asks whether you want to turn the phone back on.
