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.

Everyone is most certainly not having this issue. Force Restart your iPhone, which will likely solve this:


  • Press and quickly release the volume up button
  • Then immediately press and release the volume down button
  • Then immediately press and KEEP HOLDING the side power button. KEEP HOLDING it past the swipe to power off and KEEP HOLDING it until the screen goes dark and KEEP HOLDING it until you see the Apple Log, then let go. This stage can 15 - 20 seconds so don't let go until you see the Apple Logo

Since my last post a week ago; the next day I went to the Apple Store for help. The 'genius' said they didn't really know the cause of the problem on iPhone 16 series- even some 15s. He said he used the "technique" on his iPad at times (??), and that Cupertino doesn't really communicate with the Geniuses very much.!! But he suggested that we wipe my new iPhone clean and reload the IOS from one of their laptops- refreshed by Apple each night. So we did it and I've had no further trouble in the startup problem. I generally charge to 80% now- for longer battery life long term- and shut it off each night and turn it on (fingers crossed) each morning with no problems recurring. Another customer sitting across from me was listening to the conversation as another 'genius' was helping with her problem. It was the same one!!, and she mentioned that when she came in, she heard another customer with the same problem. So out of about 50 people at least 6% were affected. My man said that when they put a new IOS update out, they (like a Chinese food buffet) pick from different dishes, which are prepared by different chefs, rather than the entire update being prepared and managed by one "chef". That may account for the myriad problems (which as I strongly remember, used to be a province of Microsoft, and Apple always WAS so seamless). Additionally, the customer said that she and her father (both 16s- but NOT her Mom-14) were having dropped or uncompleted calls. I have experienced this, but so far, it is vague and hard to pin down. I think Apple needs to update firmware, and certainly, troubleshoot the IOS with a fine tooth comb. We shall see what we shall see. P.S. I'm using my 10XR-which this 16 e replaces- as an iPod in my car- no cell service just self contained with occasional Wi-Fi assistance.

I too am responding here in the hope that this fault gets the attention it deserves. My 16 plus is less than a month old. I had problems with the hands free speaker not working properly on calls within the first few days. When that was resolved I breathed a sigh of relief only to find this morning I couldn't turn my phone on at all. I came to this thread first and was shocked to discover how many others are encountering the same issue. I've done the whole volume up down thing and it's worked eventually but it's not acceptable. Come on Apple - sort it out please........

Posting in this user-to-user forum will not give the issue any attention at all, except to other users.


Apple’s formal support can be reached several ways

  • You can provide feedback to Apple at→ Product Feedback - Apple where your issue or suggestion will be recorded, tracked and matched with similar reports, but you will not get a reply



For personalized support

Best way: 

  • Install the Apple Support app on your iPhone or iPad - you can contact support directly from the app, and the tech will have (with your permission) access to diagnostic data on your device



Other options:

(Note that both of the above have options to receive a callback or chat)

You said you did a Forced Restart. Read this and for the final step, which is to hold the side power button, REALLY HOLD the side power button for however long it takes for the Apple Logo to appear. It could take 30 seconds or longer.

Are you powering the phone off to charge it? It is NOT necessary to power off your phone to charge it. It actually goes against the best advice. Charge your phone, when you sleep, with Optimized Charging turned on and your phone connected to Wifi so it will charge for the next day and backup to iCloud every night.

The exact same thing has happened to me this morning! I charged it all night and this morning it doesnt turn on! What do I do?
  • Press and quickly release VOLUME UP


     then

  • Press and quickly release VOLUME DOWN


     then

  • Hold the SIDE button until an Apple logo appears (15-30 seconds), ignoring "slide to power off" if it appears


The operative word here is QUICKLY; and try it a couple of times, the timing is a little tricky. If done correctly this will always work unless the phone has a hardware problem.

firstly I unplugged the phone and then plugged it back in, then pressed the up button and down button then pressed the the on button and then let it go, I did this several times before it worked so try several times and when pressing the on button hold (try various lengths of time) then let go it took me about 5-10 minutes of trying this but it eventually worked, I hope this helps you

The procedure you're using won't power it back on. Follow these directions --> Force restart iPhone - Apple Support (CA)


There is no need to power it off when charging. It's simply not necessary.

In our experience just keep trying. Up, down volume and then hold the power button a really long time. Ours took longer than 30 seconds. We have 2 iPhones 16 and both have done this numerous times u til we took the advice not to turn it off. We use focus, do not disturb with the calls we want to come through in emergency.

just keep trying the above method. It made zero difference for us to power it on while plugged in and it’s not the charger as some have suggested. It’s the PHONE and we are waiting for a permanent fix. Good luck. One day mine took 3 hrs of intermittently trying to get it on. Then don’t turn it off at night while charging or it’s, here we go again!

After mine died, charged it for a few hours with a magsafe charger. Waited until the charger showed the phone fully charged. Removed phone from its cover and performed the vol up/vol down/power reset several times. The reset maneuver is easier to do with the bare-bones phone. On the 4th or 5th reset attempt I held the power down for about 3-4 minutes and thankfully it finally turned on. After it booted, I updated to 18.2.1.

Thanks for your suggestion.

I wish I’d never have gotten rid of my old phone. It worked perfectly. The iPhone 16 sucks. I never turn mine off anymore cause you can never turn it back on. What a shame. 😥

Well, maybe there is a hardware problem with your iPhone. I can turn mine on or off when I want to, and it always turns back on. I suggest you contact Apple Support:

Update: I finally visited T-Mobile, and the salesperson there followed the same steps suggested in this thread. They clicked the up volume button, then the down volume button (in quick succession), and finally held down the button on the other side for approximately 30 seconds. As a result, the phone started up. However, this shouldn’t have happened in the first place. We should have had the phone available and turned it on, especially considering that we were expecting an important call.

While it is called an iPhone, it is actually a very powerful pocket-sized computer that can incidentally make phone calls. And like all computers, it will crash occasionally, and that’s what happened. To minimize the probability of that happening it may pay to restart it occasionally→Restart your iPhone - Apple Support


The easiest way to restart it is to say “Hey, Siri, restart this iPhone"

Problems as above with iPhone 16. Just switched off the phone. Tried to switch on and performed above actions-pressing both sides etc. but still not working- mobile fully charged, just plugged into power socket to bring up apple icon - but nothing happening.

The operative word here is QUICKLY for the first two buttons, then a long hold for the SIDE button; and try it a couple of times, the timing is a little tricky. If done correctly this will always work unless the phone has a hardware problem.

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.
