Q: Screen stays dark when alarm goes off in the morning

I have the same problem.  Now up to iOS9.1.  None of the iOS 9 updates have fixed the problem.  Sent a bug notification to Apple. Seems like a pretty common problem with no fix for quite a while now. 

I've updated to 9.1 and my screen still stays black when my alarm goes off in the morning. 

mikerisner - great observation! I didn't even realize that until you mentioned it.

It does seem to be a larger issue than the screen remaining dark during alarms, as others have pointed out. My display also fails to illuminate when I unplug it from charging - which it always used to do. On another couple of occasions, I've unplugged it from charging when it's dark and the screen is very bright (I have my brightness adjusted to dim when the ambient light is lower - this appears to the the "normal" display brightness).

Crazy.

Just a couple of notes. I was wondering if low battery mode could be a culprit, but the other day I went to bed with 44% battery, plugged my phone into the charger and when the alarm went off in the morning, the screen was blank.

Also, the past couple of mornings, I've had trouble getting the alarm to snooze when the screen was lit up. I would tap the snooze link on the phone, it would blink indicating that it felt my touch, but the alarm would not stop. I only get a couple of tries before the screen goes dark (though the alarm is still going off) so I end up having to press the side button to snooze. Grr...

I want my old alarm clock back.

Sometimes the screen stays dark and won't wake. I have to hold home and sleep for several seconds and reboot the phone to make it stop.  Sometimes it does light up but doesn't respond so I have to reboot.

Clock must be the buggiest app. Remember the New Years bugs from a couple years ago?

HI,

contrary what I told in my previous post, there is no relation with the percentage of charge but only with the time the iPhone stay plugged.

Here are my tests :

26/10 - 77% - 21:00..06:25 pb (09:25 plugged)

27/10 - 68% - 23:30..06:25 ok (06:55 plugged)

04/11 - 30% - 23:55..08:25 pb (08:30 plugged)

This problem occurred not only with alrm clock but with all notification that should turn on the screen.

best regards

Glad it's not just me. Ever since the 9.0 update I've been fumbling around in the dark, trying to find my phone to shut off the alarm. I hope Apple fixes it soon.

Hello,

It is morning if the phone worked properly, has been on the screen to sound the first alarm of the day. Unlike previous days, I have not slept and was charged with taking a 40% battery.

I'm afraid we have a problem in the cable phone charger in my case would I have as an extension to the pen between the plug and mobile, but from the first day that I have the iphone 5 have it so ... it might not this cable correctly.

I'll try again is to leave it charging overnight without the extension and if it works it will communicate.

A greeting

I have this same issue!!!! It's so annoying! I hope apple fixes this soon!

I also have this annoying problem on an iPhone 6s, running 9.1.  The other 6s is fine.

I have also suffered this strange phenomenon and I have figured it out. It seems that when you have Do Not Disturb turned on on a schedule the chances are that your alarm is set to trigger during this scheduled DND window. If you alter your DND settings to finish before your triggered alarm time you will notice the screen lights up when your alarm goes off.

This didn't used to happen and seems to be a "feature" of iOS 9.

See how you go with that.

That was the first thing I considered however my DND turns off at 06:00 and my alarm goes off at 07:00 with a dark screen.

I Have a 6s plus and it doesnt light up in the a.m.

Hi VampiressX

That is an excellent suggestion to try, and we did so this morning on my wife's 6s.  Setting the DND off time to 7:30 and the alarm to 8:00am.  No joy, the light did not come on with the alarm, and the screen does not respond to touches.  (You can wake it up with the home button).

At the same time, on my 6s, I set the DND off time to 8:30 and the alarm to 7:59am and it worked perfectly, lighting up.

I think I may give it until iOS 9.2 and then take it in to the Genius Bar along with a printout of this forum thread.

I have considered a complete wipe and fresh install (ouch).  As I read on Daring Fireball, if they want us to trade phones each year, they're going to need to make it a seamless process!

Thanks for your idea!

Thanks to this thread, I have forgotten to even look at my phone half the mornings when my alarm goes off, since I almost always press snooze. Now that I know to press the volume buttons to snooze, I'm all good. However, I noticed this morning that the screen was on when the alarm went off the first time. I also noticed that when it went off again, and I tried to use touchID to turn off the alarm, it didn't work, but it usually works. This isn't the first time.

I have DND set to turn off at 6am, and alarm at 6:30, so I've never had the alarm going off while in DND. I'm also now running 9.1, but I know that 9.1 didn't initially solve the problem.
