My iPhone won't turn on

I followed the instructions for a forced reboot and it worked.

1. hit up volume button one time
2. hit down volume button one time
3. hold down the button the other side until you see the apple logo come up. (and yes - it did eventually come up on an otherwise black screen)

I tried everything is this threat without success.

Connected iPhone 15 Pro Max to my car thinking I could restart it using CarPlay.

iPhone immediately restarted and is now working fine.

Before restart briefly saw "device is non-compliant" warning message so I guess the wireless charger that was connected to all nigh caused the problem.

it just worked for me i quickly pressed the volume up once and quickly pressed the volume down once and then i held the power button till the apple popped up

Hi everyone,

The same thing happened to me, except I was unable to turn my phone back on. My iPhone 15 was working completely fine in the morning. After about ten minutes, my screen was black and completely unresponsive. I tried all of the above fixes and nothing worked. I took it to the Apple Store after work and they tried to restore it with a Mac and that also did not work. They told me it was a hardware issue and they'd have to replace the hardware, but because of a small crack on my screen they could not do so without charging me $300 to replace the screen. I ended up having to go through Verizon (my warranty provider) and get a completely new phone.

Yup happened to me this morning! iPhone 15.

my alarm went off at 630 am but my phone screen was black, wouldn’t turn on at all. I pressed all the buttons, tapped the screen….nothing. Forced reboot didn’t work. I fumbled around with the side buttons more, flashlight flashed and it made a weird noise nothing happened…fumbled around more flash light flashed brightly it made a noise nothing happened. I started to panic, plugged it into charger and it came back on within 7 mins……weird cos the battery life is and was 100%. This needs fixed cos my phone didn’t need charged, let alone plugged into the charger… it wasn’t even plugged into the charger when I woke up to a black screen, useless iPhone with the alarm blaring….it acted as tho it was completely dead when it wasn’t.

Also, got a notification that my iPhone initiated, emergency SOS at 635 AM because the side buttons were held down.

well…. That wouldn’t have occurred, had my iPhone been working properly and not playing dead.

Same here. Charged all night. Woke up to everything working but had a black screen. Take it outside into direct sun. Within a sec it will come on. This has happened to me twice now and this is how I fixed it. Hope this helps.

Happened to me also. I charged my iPhone overnight and once I needed to look up something it was black so I decided to hold down the power button and volume button but nothing happened, no Apple so once I let go I heard a screenshot sound so I pressed the two buttons again and heard another screenshot sound. It’s like my phone is alive but in the casket. 😂

it just turned on. I asked siri a question wondering if she’d respond and she did but when she wouldn’t read me what she found I gave up so I pressed the power button and it turned on. I don’t know if that’s why it turned on but it took 10 minutes.

I also woke up to a black screen. Had to do the above mentioned force reboot three times before it worked. Really frustrating.

Same thing happened to me. Tried to restart using volume buttons and power button and I'd get siren. The flashlight even turned for a while one time. I asked Siri to reset the phone, but it advised me to unlock the phone first which I couldn't do. Anyway, I took a break and when I got back it was back on. The phone was unusable for about five minutes. This is the second time it happened and each time it happened it was sitting on a wireless charger.

Iphone 15 Pro Max this happened to me over night. I had mine on wireless charging and noted in the middle of the night that the desktop clock was not on. Took of charge and nothing came on the screen. Hit the volume up and side button, alarm went off along with the flashlight. Finally found the force restart procedures and it came back on.

This has happened to me twice and I have only just got my phone working again. I got my iPhone 15 in December and have had no issues with it until this week. The first time it happened it was right before a school trip to London which I really needed my phone for and I woke up to my phone on a black screen but all of the buttons were working. I used the volume up button and the side button but it made the flash turn on and an alarm started and phoned 911. After 10 minutes it turned on again. It was fine for a couple of days until it happened again this morning. I thought it would turn on again like it did the last time but it didn’t. Me and my dad tried to sort this out by doing a bunch of stuff like force restarting it and leaving it to charge but nothing worked. I let it charge again for half an hour and then I did the volume up, volume down and pressed the side button and it worked again after two hours. This shouldn’t be happening and from what I’ve seen this has been happening from September 2023 up until April 2024 and Apple still hasn’t done anything. This is very impractical and really annoying so Apple please sort it out.

Same thing happened to me this morning it was on the charger overnight my iPhone 15 pro max which is still covered under apple care.. I woke up to a black screen tried what they said all I got was a siren.. I finally called apple and because I live 2 hours from the local store they are sending me out a new iPhone and it will be here tomorrow. Needless to say it just went back on by itself.. This is not acceptable Even though everything is backed up to the cloud I still have apps that don't transfer over and this is a big pain in the ***...Its like your phone has been taken over..At least they are sending me a new iPhone

The exact same thing just happened to me with my practically new iphone 15 pro max (that I've had for less than a month.)

Charged my phone overnight, the alarm woke me up this morning but the screen wouldnt turn on at all. Calls still coming through to a black screen. I turned the phone on and off but still nothing.

forced reboot saved my device. It definitely works - please do this first if you find yourself in the same situation.

I just had to have my 15 Pro Max replaced less than 30 days after purchase due to the same issue. My phone was plugged in over night and when I woke up I tried to login to my email on my phone and then the screen went black. It kept cycling between off and the black screen with Apple logo and none of the reset methods worked. I took it to the Verizon store and they couldn't fix it but replaced it because it was less than a month old.

So disappointed in this product. The cell signal also wasn't very good from the beginning and the battery would get extremely hot when using FaceTime or playing games like Roblox. Hopefully the replacement lasts longer. Not sure how much longer I'm willing to put up with faulty Apple products.
