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.

My thought was that if enough of us make a stink apple might put some resources into solving this issue.

Making a stink here on this user to user only forum, which Apple doesn't read for feedback is kind of pointless. And assuming most people have such an issue is also not reality. I have two iPhone 16 Pro's (one Pro and an Pro Max) and I know many others who own an iPhone 16 Pro, and none, including me, have any issues.


The best solution for anyone who is having an issue, is to show their phone to Apple at the Genius Bar. Complaining here will really accomplish nothing.

Tech support agents never do nothing to give us a real fix. All they know is the reset mantra that never sorts out things.

I’m having issues with Spoken content and the Siri neural engine text to speech in my iPhone 11 after reinstalling iOS 18, I spoke with 3 agents and absolutely none of them were willing to help me. I speak Spanish as my native language and the voices that i’m having issues with are in Spanish, so the agent told me that nobody from the accessibility support speak Spanish, so he refuced to continue helping me.

If there are millions of iPhones around the world, I’m sure that a vast majority of them are having an issue, doesn’t matter if it’s hardware or software, and Apple never does nothing to correct them unfortunately

Please help me. I’ve tried everything. Yes, I did have it plugged in when I turned it off last night. I don’t think it was fully charged when I turned it off. Have only had it for a week. So glad I held on to the 13 max pro I told my dad I would give him. What about people who do not have Mac computers or computers at all?

Update: If you try the hard reset with no luck, you need to go to the Apple store. They attempted a manual hard reset and nothing. They have a mechanism in the store that they can run to basically for a reset that is not the volume up, volume down, power button, and nothing. They also ran an HDI to power on and he said it was essentially a "this phone will never power on ever again." They do not know why it did this and the phone was received 1 month and 4 days ago. Going to the Apple store and them running the HDI to power on will definitively tell you if there is any hope left in the phone. It's wildly inconvenient but at least there is an avenue to get answers.

So I have the iPhone 16+, which I bought and set up on December 8, using the side by side method from my iPhone 11. I had my battery down to 7% last night before I plugged it in to charge (using the USB c cable that it came with and a 12V adapter) before turning it off for the night to let it charge. My iPhone 16+ is on iOS 18.2.


This morning I could not turn the phone on, so I had to keep trying using the reboot method - I plugged it into charge further thinking perhaps my charger didn't work, eventually it just randomly turn back on, I couldn't even set up a Genius Bar call since I couldn't turn on my phone for it to receive 2 factor authentication at first.


After looking at the responses here, it seems like:

1) I should not turn off my phone and charge overnight

2) I should get a 20V charger?

3) Set optimized charging to less than 100%


I will try these solutions and see what happens, luckily I'm still in warranty and now I think I need to get the additional one year AppleCare for an extra $200.

Mine was not shut off or close to dead nor was it even charging. I fell asleep with it on my side table and it was fully charged when I fell asleep. Woke up and it wouldn’t turn on even when I plugged it in. I had to do the hard reset to get it to turn on while it was plugged in or it didn’t work. When it turned on, battery was 80%, the max I charge it to. I literally did nothing different than any other night. It definitely didn’t update because it wasn’t plugged in.

Have you updated your iPhone to iOS 18.2?
