On the IPhone can an alarm still go off if?

Will an alarm still set off on an iPhone even if you are in "Do Not Disturb Mode" I never turn on the Do not disturb mode so i'm not sure if the phone stops ringing for everything or if an alarm will still go off. Cause blackberrys alarms will go off even of your in silent mode but this is my first iPhone so I have no close. My model is the iPhone 5 with all my updates!

P.S- anything else about "Do Not Disturb" mode that I should know?

I can't understand what is preventing you from testing this question yourself.

Alarms will still go off in do not disturb mode. You will not receive notifications including text message notifications. You will also no receive phone calls unless someone calls you twice within 3 minutes, in which case the phone will assume an emergency and let the call come through. You will still receive texts, tweets etc, but you will need to open the apps to see them while in do not disturb. You can also set this feature to be activated on a timed schedule.

Also, iPhone will let alarms sound while in silent mode as well.

  • Will my iphone alarm still go off when i have an app running overnight? I've had sleep cycle on my phone for around 5 months now, but I haven't had the chance to try it out yet. I'm normally a very heavy sleeper and I have to get up super early in the morning which makes me even more sleepy. I want to see if it will work for school or if my 4 normal alarms will wake me up.
  • 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)?
  • Will iPhone alarm still go off? I want listen to iphone as i go to sleep but i also need it as an alarm to wake up in the morning. I know that the earbuds will probably fall out of my ears so i want to know if the alarm will still go off through the speaker of the iphone itself instead of just through the headphones? Good thing school is almost over ill only need to use this two more times.
