Why doesn't my alarm go off on my new iphone5?

Whenever I turn off my phone, I leave the sound on and everything else in check. But it still won't sound, why does it happen? What do I do in the settings to make it turn on? Because I have to lock the screen in order for it to sound, and leave it on all night. I don't like that it wastes money on my phone bill. How do I fix this in my settings?

It doesn't use your minutes or data limit to leave the phone on. If you're worried about data just either make sure it's on your wi-fi network or if you don't have one just turn off the cellular data.

Check volume

  • Why doesn't my alarm clock sound off on my iphone? Although it "alarms" when it should, it doesn't ring, it only vibrates. Does anyone know how to fix this? P.S I had a 4 day weekend last week, and I kept leaving my phone everywhere, so I didn't get to turn off the alarm clock for maybe 3 days, so maybe this is the reason?
  • WHY DOES MY ALARM NOT GO OFF ON MY IPHONE? I set multiple alarms and turned on the ringer and turned the volume all the way up but it didn't go off. Also i quit everything in multitasking except the clock app
  • The alarm goes off at times I haven't set on my iPhone5 (last year's). WTF? I work shifts and I set it every week on a different shift pattern. I previously thought I set it to go off at the wrong time but it has definitely gone off at a time I didn't set. The time it went off, that alarm was in the off position with no days assigned to it at the time. It wasn't the shift I had last week either (it didn't get it mixed up/carry it over from last week). What can I do?
  • My iPhone alarm doesn't play the song I want? I have always woken up to the song Super Bass when I had my iPhone 5… Well after some unfortunate events I ended up getting a new iPhone 5. Everything is the same but… When I wake up it no longer plays the Super Bass song! In fact it still appears that I have chosen that song but only vibrates when I wake up! Someone help me! I LOVE SUPER BASS!
