Screen stays dark when alarm goes off in the morning

I am not sure if it makes any difference whether it is plugged in or not.

• If I set an alarm to go off in a few minutes as a test then the screen will come on whether the phone is plugged in or not. (I tried both just now)
• If I leave it inactive overnight then the screen won't come on with the alarm.
• I don't know if leaving it unplugged overnight will make a difference as I always plug it in at night.

I'm not even 100% sure it'sjust an alarm issue. If I plug my phone in now, turn the screen off and then unplug it the screen comes on automatically when it's unplugged. If I plug it in at night and then unplug it the next morning it doesn't light up. It seems like the phone goes into some deeper sleep or something when left for a few hours.

This is the exact same results for me. I have run a few tests on the weekends and it seems like if its more than ~4hrs the screen does not wake on the alarm. Less than ~4hrs it wakes.

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.

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.

This is the exact issue I have. My phone remains face up and if its idle for a few hours, it will not light up. If I set my alarm for 10 minutes from now, it lights up as expected.

I have the same annoying issue. Monday was a holiday therefore I cancel my Weekdays alarm, Monday night I turn on the weekdays alarm on and Tuesday AM the screen lighted up when the alarm went off (it worked !!!. NOT) This morning however the screen did NOT light up when the alarm went off.

STILL NOT WORKING on my iPhone 5 IOS 9.0.2

I have this issue too. 9.0.2 update has not helped. I can't snooze, as soon as I touch the phone, the alarm turns off.

I bought an iPhone 6S and traded in my 5S but honestly, there are so many annoying little niggles with iOS 9 that if I hadn't traded in, I'd go back to 5S and iOS 8. I've had more problems and spent more hours with Apple support about iOS 9 than I have in my entire 15 years with Macs.

I would also say that the quality of support has dramatically deteriorated. I had an Apple ID/ Family sharing issue which I sought advice for via emailing support, talking to the guys in store and an hour on the phone with support, couldn't fix the issue. In the end it was a simple field that no one had mentioned before. Apple seem to be in such a rush to release product (I've heard whisperings of a bloody car!) that their ease of use for the consumer and their employee knowledge have taken a massive hit. It's a real shame.
