iPhone 16 Pro not turning on

I own an iPhone 16 Pro running 18.0.1 and have the same problem everyone mentions here. Every night, when going to bed, I plug my phone in and turn it off. The phone not turning on has happened twice, so it's inconsistent when it doesn't want to turn on. The up, down, and on always seem to work. It turns on with 100% battery, meaning it successfully charged overnight. Doing a reset to turn on a brand-new phone implies something is wrong. I don't know if it is hardware or software. Hopefully, Apple acknowledge and address the issue soon.

It might take a dozen two dozen or three dozen times maybe even 50 or 100 times (my last time it took at least 50) but it did come on you have to do the hard reset quick volume up quick volume down hold the power button. Hold for about three seconds maybe five nothing happens do it again. My phone is set to charge to 90% as soon as I saw that that was a possibility. And the problem reoccurred. Three times this has happened to me twice I’ve gone to Apple support. And twice they have essentially said we got nothing for you. The best they gave me was delete and reinstall all software that is set your phone up as a new phone. So today after I get done work run all my errands. I’m gonna sit down for the hour and a half. It’s gonna take the back up the phone to my computer and try that. Sorry Apple that’s a lame *** answer.

My NEW iphone 16 has had issues turning on as well. I've had to force restart (vol up vol dn, press and hold power button for 10 + sec) several times to finally turn on. 100% charge. First time I've ever had this issue with any iphone through the years. Initially, I thought that it was a power cord or charging pod and that the phone had no power. But now that I have read these comments I'm thinking that it's a manufacturing issue. Hopefully it's a software correction Apple can make in the near future and not a hardware issue. Thanks to all for helping me gain perspective on this one!

Currently dealing with the same issue. I woke up and my phone will not turn on. I've tried several things. The logo will pop up, then disappear and will just keep doing that. I've tried plugging it in and that also does not work. Just bought this phone brand new last week. I've got a busy day and no phone. writing this from my MacBook. smh.

This happened to me repeatedly. Three times. Spaced out by about five or six days apart. It started about a week and a half after I got the phone in Early Sept as a preorder. I happen to have an Apple Store near me so first I used a chat help. They gave me the hard reset solution. First time it took about 12 or 13 tries. Second time took over 50. Third time I did it for about 45 minutes on and off. I think it took in excess of 100 times maybe 150 times. But it did come on. I brought it back to the Apple Store and they told me that I had to delete everything and reinstall the software in order for them to determine if it was hardware or a software problem. This I did and it reoccurred. I went back to Apple Store got a replacement 16 Pro and after a nightmare losing I my phone number for a day with T mobile not able to sort out how to fix it, due to the terrible tech I got from Apple. now I have my phone working again. I’ll let you know if the problem occurs. But I had to go to the Apple Store and get a new iPhone 16 Pro.

This happened to my iPhone 16 pro today, still not on. The apple logo comes up and then goes right back to off. I have had this phone a week, this is ridiculous. A force restart is not working either, I did have it charging over night as well and tried charging it again but still nothing. Apple…you need to get it together!

Your device may be in dfu-mode(device firmware update). Conmect your device to a mbp. The system may ask you whether it should reset your device, or tell you to download some extra software (also look underneath the running window). Tick the reset button. The system will do the rest. If this does not provide the solution for you, you may have to make an appointment with the genius bar at the nearest apple store.

Having the same problem on iOS 18.1. So frustrating!!

I got mine fixed by using the technique that Apple support told me to do since I took it to my local store, and to be safe I put charging at 90% and use a usbc charger instead of my MagSafe. If you want you can try this

Expanding problem that Apple is trying to avoid acting on…since it is random it seems more and more like hardware related. Possibly batteries that are defective?? Looks like I better get apple+ coverage … never thought I would need it but this is not a good situation!

You asked how those with problems initially set up their phones. Both iPhones 16 Plus were set up by the side-by-side method. The one at 18.0 would not boot up after an overnight shutdown and fully charged up. Not using MagSafe. Using a regular cord method. It took me about two dozen force restarts over a 4 hour period to finally one worked. That phone was shut down for the first time today, because we had no important tasks on it, and I updated it to 18.0.1 when it was 80% charged. It booted up normally afterward. I have set both phones to an 80% max, as I am trying everything to prevent another failure - I doubt Best Buy repair can fix it, and the nearest Apple Store is a 3 hours drive. The 2nd iPhone 16+ survived the update, but once when I was in the middle of something it instantly shut off and then rebooted by itself. These are my 4th sets of iPhones and I have never had any problems with prior models. I hope this can be a software fix and not an endemic hardware problem. Toms Guide mentions other problems, but not this not booting problem. I am unsure if I should go to Apple Support or to the cellphone carrier to kick this issue upstairs, but how can I do it with currently working phones?

Just happened to my daughter's phone this morning, so maybe it's just a matter of time for all the 16's. She used the charger the phone came with and her phone is updated to 18.0.1. Took about 30 minutes to force start it.

It is a lemon. Back the phone up to a computer. Do an encrypted backup. Then wipe the phone and reinstall the software new. Then go ahead and restore your phone using your encrypted back up. And when it happens again, and it will take the phone to the Apple Store And or if they’re not close, call Apple and tell them to send you a new phone. That’s what I had to do. And I’m still not sure the new one is going to work properly. i’ve only had it a couple days.
