Why does my iPhone 6 alarm clocks not go off?

I have 6 alarms set; 5:00 am, 5:20 am, 6:45 am, 7:00 am, 7:15 am, 7:35 am. All of them are set to go off every weekday. I depend on them to get up super early for showers and whatever. Well sometime they don't go off, and I thought maybe they were going off but I was turning them off in my sleep but today I was laying in bed, not asleep but with my eyes closed and waiting for my 6:45 and it just never went off! I checked and it is set for every weekday. And it's not the volume because the 5:00 am one I heard and my 7:00 am one I heard Why does my iPhone 6 alarm clocks not go off

This is MENS HEALTH smart one… Smh

  • Will my iPhone alarm go off with headphones plugged in? I like to listen to music before I fall asleep, but I use my iPhone as my alarm for work in the morning. If I fall asleep with my headphones in, will the alarm still go off (like on the phone speakers, not just the headphones)?
  • 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?
  • 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 the iphone alarm stop ringing after 15 minutes? Like honestly who designed this piece of ****. If i set an alarm i expect it to ring forever until i wake up. Now i slept through my alarm with 3 hours of sleep and end up waking to no alarm and by myself. Why the fk does it stop ringing by itself after 15 minutes ******* dumb apple
