Will the alarm ever stop?

I agree with Super too, I left my iPhone at workplace a couple of times with a 7.30 am alarm set .When i reached my desk at 9 am the alarm was not ringing.The alarm appeared on the lock screen waiting for me to snooze.So i would say it rings for may be between 10-20 mins and then goes silent.

I too wrestled with this and came up with these solutions. Firstly, I used a song as my alarm (just want to be precise as to what I did, not what needs to be done). On my iPhone 6+ I set a second alarm 10 minutes later using "no sound" as the sound. This resulted in the first alarm getting silenced! Problem was this did not work on my iPad Pro! The fix there was to "purchase" a $1.29 "Silent" ringtone from iTunes and using this ringtone for my second alarm sound. This may change as Apple fiddles with IOS updates but as of 10.2.1 this works for me!

My iPhone's alarm is limited to 15 minutes before it turns itself off. (If I know it's going to be a short night I set it out of my reach, so for the times I've been too exhausted to get up and hit the snooze or turn it off, it has gone on for a full 15 minutes before stopping.)

Nope, fifteen minutes, then a nine minute snooze...

I have yet to find a setting to adjust the duration, but I believe the iPhone alarm will stop automatically after twenty minutes. Give it a try.

God it's like being in a cult. I can't get an answer to this either. There is only one right way to think and you and I don't have it. Like you I want an alarm that turns itself off once it realizes that nobody is going to do anything about it. A minute is way long enough. Forever is too long.

Yes, until you turn it off or snooze it.

good to know!🙂

i just WISH i could set the snooze or alarm to automatically go quiet after like 30 seconds, without me having to get up and press anything!

know what i mean?

Sorry, but I don't have my phone on me all the time. But I do check for miss calls/text etc... I don't need an audible signal to alert me... If I check my phone I'll see a red one on my phone app indicating a miss call.

If you set an alarm, wouldn't you already be near your phone to snooze or turn it off?

Ok, that makes sense...

I SO wish I could do this too. Is there maybe an aftermarket app that behaves this way?

Is there a way to program the alarm to go off after 2 or 3

Minutes ???

Nope

My iphone will stop ringing after 20min i guess.

Is there any settings for this ?
