iPhone 5 alarm not working

I Just had the same problem, the alarm wasn't working. What I did was set certain alarms to go off on specific days of the week, so when I changed the time, the DAY was still set for a different one.

So today is Monday and the alarm didn't go off at 7am because the day was still set for "every Saturday ". I deleted all the alarms, started new and everything is working fine.

I had this issue with my 5s. I just assumed it was because it was old and needed to be replaced. Today I was late to work because the same thing happened with my brand new iPhone 7...... This is not good. I rely on my iPhone to do many things, but if it is going to keep biting me in the rear, I will have to figure something else out. I would rather know how to fix this issue, especially since I paid a lot of money for this phone.

Did you set it up by restoring from a back up from your 5S? If so, try setting it up as new and testing.

I understand it's a very, very frustrating problem. Unfortunately, though it has been a problem a number of people have had over the last few years, it's never been a very large number of people. That makes it harder to figure out what might be happening.

Other things probably already mentioned in the thread that have helped some people:

- Delete all of your alarms and add them back

- Use only built in alarm tones, not music

- Double check Bedtime and make sure it's not set to go off at the same time as your alarm.

Best of luck.

Quick question to that - if another notification goes off at the exact same time, will they cancel each other out or one overrule the other? (Just asking about sound)

reason I ask is because you said "Double check Bedtime and make sure it's not set to go off at the same time as your alarm" and I did have a couple of email notifications this morning on my phone. Could this be part of the problem?

They are not supposed to. I know I get several alerts at 8am and I hear them all, one after another. However, I haven't tried seeing what that will do to an alarm. You could try putting your phone on Do Not Disturb overnight. That won't affect the alarm.

Basics from the manual are restart, reset, restore from backup, restore as new.

Try all these steps in succession until your problem is solved. If it is NOT solved after going through ALL these steps, you'll need to bring your phone to Apple for evaluation.

My iPhone is my only alarm clock. Never had it fail. Have you tried resetting your device by pressing and holding the Home button and power button until the silver apple appears? Have you tried restoring it as new?

Until you get the issue resolved, perhaps your husband should buy a cheap alarm clock as back up.

Best of luck.

I am having this problem too and my iphone is new. I will try resetting it, the alarm goes off but the sound/vibration is turning itself off. Generally it works the first time and the next time it does not. I have found that I checked the slide button for sound and it will be off but I did not touch it. The alarm does go off but there is no sound of vibration to wake me. I have seen some others are having this problem. Hopefully resetting will work. thanks

I have also had the same issue several times. I reset my iPhone 5 twice and restored. This did NOT help. Our alarm was supposed to go off at 5am this morning, we woke up at 7am and the iPhone screen said, "alarm" but no sound was coming from the phone. What is going on here apple? 2300 people have looked at this page, probably a fair guess that most of them are having these issues. Is this a bug???

Have you tried going into settings>sounds and switch OFF - ringer and alerts - Change with buttons.

having the exact problem as Nixteen with 3 month old iphone 5, does not function about every two weeks.

Have tried all suggestions but once again this morning, failed to ring

2 weeks I have been thinking it's just me. Getting to work late is frustrating and when I stay at my ladies I have to rely on something I thought was reliable. Looking at this I won't use the iPhone alarm any more. Had to be at work at 3 am woke up at 255 am alarm going off with no sound. I even checked it before I went to bed setting it for a minute after I set it. Then it did go off but the 155am alarm never made a peep. Very frustrating.

Same Problem as Navqueen. I called apple support months ago, they had no clue how to fix it. I love my phone but my next one will be an Android I can assure you. This is unacceptable.

This may sound stupid but there are two settings you need to check to get sound. Recently mine turned off for no reason. First, go to settings>sounds and there is a bar that says "ringers and alerts". Make sure the volume here is all the way up.

Secondly, on the alarm menu, edit the alarm that is not sounding. Beneath the alarm time, you will see a section describing "repeat", "label", "sound" and "snooze". Click "sound" and make sure you choose a sound. If "sound" says "none" then it will not play.

Like I said, these turn of randomly on me all the time when updating and doing other things on my phone so just check them.
