Screen stays dark when alarm goes off in the morning

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.

I have updated to iOS 9.0.1 and continue to have the same problem of the screen not lighting up when the alarm sounds, as it has always done until the iOS 9.0 update. Needless to say this causes a problem finding the phone to shut it off.

I have updated to 9.0.2 and continue to experience the same issue, as well. The alarm goes off, but the lock screen remains black. Have to fumble around in the dark to find my phone, then press the home button to illuminate the lock screen in order to snooze or deactivate the alarm.

The problem started with the iOS 9 update.

I'm actually surprised that more people haven't mentioned this. Hope it's addressed in the next update!

I noticed this when I upgraded my iPhone 5s to iOS 9. It followed me to my iPhone 6s Plus. Some mornings, the screen wakes up and I can swipe to silence the alarm. Most mornings, it stays dark. And this is happening right when the alarm begins to sound.

The problem has persisted through 9, 9.0.1, and now 9.0.2.

Deep sigh.

Do any of you have an Apple Watch? I had enabled nightstand mode on my watch but dont use it because I want to be able to see the time. i disabled nightstand mode and that seems to have helped as my once dark screen is now lighting up again.

I have the same problem.

I updated my iPhone 5 to iOS9, and also to 9.0.1 and 9.0.2, and in all versions fails. I have the "Do Not Disturb" active at night.

There is any way to fix this?

Well, I suppose I'm happy to hear it's not just my phone and also that it seems related to the OS rather than my new 6s (hadn't updated to iOS9 on my old 4s).

However, I haven't seen anyone chime in with a reliable solution anywhere online. Has anyone found a way to solve this? My impulse to hit the home button (which just turns the alarm off for me) rather than the power/lock button (which apparently will snooze) is not optimal for my ability to get to work on time.

No solution yet here - and I'm definitely finding that the behavior noted is NOT happening consistently. Not sure why that is. Some mornings, the screen illuminates with the Snooze button as it always has. On other mornings - like this morning - it doesn't. It remains completely black while the alarm is sounding. I've been pressing the Home button in these cases, as well.

Not optimal - certainly hope this gets fixed in the next update.

I am having this same issue. iOS 9.0.2 on iPhone 6S.

It was happening on my new phone upgraded to 9.0.1 and the issue went to intermittent. Just finally upgraded to 9.0.2 and its back to occurring all the time.

My work phone and my wife's iPhone 6 on iOS 9, 9.0.1 and 9.0.2 never had this issue at all.

I have same problem but the strange thing is that it only occurs when the phone has been idle for several hours i.e. first thing in morning when I most need alarm clock to light up. If I test the alarm any other time such as setting 1 minute ahead of current time it will light up always. It does not matter if cord is plugged in or not. I have tried to contact Apple care support but they have no answers. Hopefully either firmware or software update could resolve this aggravation. I am glad to hear that I am not only one with this problem.
