My iPhone alarm clock turns off by itself?

It's really annoying, since I need it to wake up for school and work. I usually have a double alarm going and both usually shut off. I turn that switch on the side of the phone that's orange to silver, and I make sure the volume is all the way up. I have a 4s. Any idea how to fix it and why it does this?

The silent button won't make a difference and neither will the volume button trust me, even if your phone is on silent and your volume is turned down the alarm will still work, try deleting the alarm and setting up another one and make sure repeat is on so that you don't have to have 2 alarams

  • 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?
  • Onomatopoeia for an alarm clock going off? I'm taking about the classic alarm clocks or the digital clocks with built in alarms… Not iPhones. I wanted to use "BLEEP", but it sounds bland. Does anyone have an interpretation of what alarm clocks sound like? I need as many suggestions as possible.
  • My iPhone turns itself on and off randomly? My iPhone 3GS has just started turning its self off and on like 20minutes ago and it's got 57% of battery left, I don't know what's wrong? And I don't wanna go to the apple shop because I don't want my mum to have to pay for a new one because we have a tight budget. And if I tell her she will go mad!
  • Is Sleep Cycle Alarm Clock (the app for ipod/iphone) safe? I've heard that it can be very dangerous and can give you brain cancer as it is next to your head and uses the accelerometer (or something like that) - Is this true?
