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.

One can do the force start and yes, it eventually turns on. Sometimes after 2-3 tries and sometimes after 40. The point is, WHY should we have to go through this time consuming and frustrating endeavor? Apple Store, the first time I went in a month ago, acted as though they didn’t know this was a problem. They have all been aware of this since the iPhone 16 was released. Also according to the numerous posts, it is all types of 16 and it doesn’t matter how one transferred data from previous phone or if it’s plugged in to charger or not, they still have this problem if one powers off their phone. Not every time, but one time is too many and Apple needs to fix it or recall these phones! Stop selling them.

This sounds good; however, since only a few people have so far commented that Apple may have been fixed the issue in this last update, my wife will be waiting before going back to her old routine of turning the phone off at night. Hopefully others will have more guts, and will turn their phone off, charge at night, and report back. This has been a long strange trip, and not one of our happy iPhone moments since owning almost every iPhone since 2009.

Follow the directions in this and for the last step, KEEP HOLDING the side power button for however long it takes for the Apple Logo to appear --> Force restart iPhone - Apple Support (CA)


Also you really don't need to power off an iPhone. I can't remember the last time I completely shut down my iPhone. It doesn't provide any tangible benefit. You should charge your iPhone when you go to bed with it powered on, connected to Wifi, with Optimized Battery Charging enabled and iCloud backup turned on. It's the best way to preserve your iPhone.

Same thing just happened to me today - the iPhone 16 PRO won't switch on no matter how long I keep the right button pressed - The battery was probably around 80% when it happened - Anyone at APPLE can pick this up? Thank God I had a space old iPhone 12 Pro in my bag which I am now using but this is extremely disappointing for a device worth 1,500 USD!

You need to Force Restart your iPhone. Just holding the side button won't turn it back on. Follow these directions and for the final step, KEEP HOLDING the side power button for however long it takes for the Apple Logo to appear --> Force restart iPhone - Apple Support (CA)

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.

i had the same problem this morning. ( Iphone 16 pro)

  1. had charged it overnight, powered off .
  2. with a 25w samsung charger.

In the morning the phone was dead.

Solution : voice up voice down and FOR about 25 SECONDS power on. Dont be afraid for more, it will power on.

Problem solved.

As a first time apple user I'm wondering if it's a warning for some hardware error or some hardware malfunction. Does anyone have an answer to this question?

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
