iPhone 16 Pro not turning on

My wife’s iPhone 16 Pro is not turning on. Several times I have had to push the top volume, bottom volume and then hold the right power button until the Apple came on. And it took much longer than 10 seconds and instead of it coming on by itself, the Apple would show only after I held and released the power button. Did she get a lemon or are others having this problem? She gets a new phone every year so this is not an operator error.

This happened again to my wife's iPhone 16 Pro. She could never get it to start. I tried 3 or 4 times with the force restart and it again would not start. I then plugged it in as a last resort, did the force restart a few time and finally it started. The battery was at 100%. It took quite a long time holding the start button after the volume up and down buttons for it to finally start. I will do a force restart on my iPhone occasionally and it never takes that long. She has had almost every iPhone since the 3G, so this is definitely not operator error.


I am responding here in hopes that it gets pushed to the top of iPhone questions in hopes that others may either respond that they too are having this issue and what the resolution is.

Same here. 16 pro max wire charged overnight. Dead as can be. Nothing worked to resuscitate the phone. Made an appoint with the Genius Bar as a final resort.

I also have the iPhone 16. Samen thing happened twice, but I managed to get resuscitatie it through the DFU-procedure.


I have bought several iPhones throughout the years, but this never happened to me before.

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?

This is the worst “upgrade” I’ve ever experienced! Every 2 years I upgrade and I’ve never had issues like I’m having now. This is a brand new phone and it’s acting like an old one, this is unacceptable and Apple should be ashamed for putting out a product with this many issues. First I had issues setting it up with iCloud so I did side by side and that worked. Now this power up issue has revealed itself. I wasn’t charging my phone when it happened, it just shut off with the phone screen going instantly black. It wasn’t dead. I’ve tried resetting it and it isn’t turning on. I tried charging it using MagSafe and usb c, nothing happens. Paid over $1000 for a POS phone. Thinking about switching to Samsung.

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.

This is happening to me right now. I got the phone a little under a month ago--brand new! It happened a few days ago and turned back randomly about 6 hours later, but now, it's not turning on no matter what I do. I scheduled an appointment with the Apple store...I am hoping they can either repair or replace it. However, upon reading this thread, I am learning that Apple has been no help. I hope this is covered under my limited warranty :(

So this happened to me. I got the phone a month ago and I started having issues with the screen freezing a week in. Last week, it turned off and didn’t turn back on for several hours. This past Monday, it turned off and never turned back on. Luckily, I was under a limited warranty with Apple so I brought it in. They said the battery was completely swelled up and melting the hardware! Luckily, they replaced it without any hassle. I am hoping the problem does not reoccur. I would recommend booking an appointment with apple because it’s most likely just faulty hardware. If you don’t have a warranty, sign up for AppleCare+.

Same thing happened to me. I turn my phone off every night and charge it (have done this for 12 years). With the iPhone 16 Pro I charge it with an Apple USB C cord overnight while it is off. Took me ten tries of volume up, volume down, and holding on button to get it to kick on. Battery is 100%. Running iOS 18.1. Very disappointing.

Yes what a pain- my situation a complete joke- I transferred digitally the sim via esim to the phone pro 16

which then died with the esim inside. It's my work number and Apple could not help here as you can't transfer a sim from a dead phone. I've had to ask my carrier for a replacement sim. I think Apple knows that there is a product fault but will not do a recall yet or blow this up as it would look bad for them. In eight years of being with Apple this is the most poorest of times with their grand new 16 pro phone- bit cheeky too to sell it with apple intelligence only for all the software not to be ready yet. May go back to my 14 pro which was excellent.

After I spent over four hours, trying the forced reboot process, the iPhone 16+ finally turned on. I am afraid to turn it off. I charge it with the standard plug. I read that Apple suggested lowering the charge percentage, so I changed it to an 85% limit.However after a few days, it charged to 100% so I went online to Apple support after I had rechecked my settings. After a while, they replied that the iPhone 16’s every so often ignore your lower setting for some kind of a battery life purpose. I advised them that defeats the whole point of their recommendation to lower the battery percentage in order to prevent the inability to turn on after being shut down. I did do an update to iOS 18.1 on both phones And I held my breath, but they rebooted OK. So where we stand is no real explanation and no real solution. It is just a matter of time. I expect the phones to not be able to boot up. I’ve been using iPhones since model 11 and I have never experienced a failure before.
