iPhone 16 Pro not turning on

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.

This is the first time it happened to my phone and I got it around 3 weeks ago. I completely turned it off yesternight before charging it, but when I tried turning it on this morning it wouldn't turn on like its usual 10 seconds. I tried plugging it again and using different chargers and different outlet, but it still didn't turn on. I tried the method of pressing the volume up and down method very quickly and then holding the power button till the apple logo showed up. It took at least 30 seconds to turn it on instead of its usual 10 seconds. This has never happened with any of my phones before, let alone a new one I recently got. I updated my phone to 18.1. Hopefully Apple can get this fixed soon because I can't do any schoolwork without my phone.

Same here man I just read over all of these reply’s while trying to power on my iPhone 16 I’ve learned the hard way don’t let it die and don’t fully turn it off Apple needs fix our glitch for what we’re paying!

Well, I’ve got bad news for you. I had the same problem multiple times jump through 1 million hoops at the Apple Store had no end of problems getting my new phone started up again because they never did figure out what was wrong with the old phone but guess what? The new phone is exhibiting the same behaviour three weeks later I get up this morning phone will not turn on 50+ hard resets later it turns on. I’ve been an apple fan since the 1984 McIntosh commercial. And I am as depressed and saddened by the quality of the products created in China by the way by this company.

Adding my voice to the chorus. Only difference is mine restarted in about 1 minute, while plugged in. Same base circumstances. 16 base 2 weeks old. iOS 18.0.1

Then why haven't you updated to iOS 18.1.1, which was released more than a week ago, which also might help you>

This just happened to me for the first time. I think the scenario was identical to everyone else—My battery is set to charge to 90% max, and then I turned off my phone. I’m not 100% certain I turned off my phone before it reached 90%, but I turned it off and unplugged it. This morning, I plugged in my phone to finish charging, and I was surprised the screen didn’t turn on. I didn’t really think anything of it for 10 or 15 minutes, and when I tried to turn it on… nothing. The force restart worked for me. What’s interesting is if I look at the battery level chart for the last 24 hours, the chart is empty starting at the point where I would’ve plugged it in to start charging last night. It also says “last charged to 90%,” and the date is the previous time I charged. All of this makes me hopeful that it is a software problem.

Happening to me for the first time with a 16 Pro I've had since October -- force restarting (tap volume up, tap volume down, hold power button) doesn't seem to work no matter how long I hold the buttons -- the phone turned off when it ran out of charge and it doesn't seem to be charging with either the original apple usbc charger with original apple wall plug, nor my macbook's USBC charger nor its magsafe charger, macbook doesn't recognize the phone, it just seems for all intents and purposes to be dead...

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.

My week old IPhone 16 was dead after a night of charging while turned off. Took a couple of hours of forced turn ons to activate it again. This is definitely a flaw and I do NOT recommend this product. Wish I had my old one back.

The person did what’s known as a forced restart. It’s what Apple recommends as a first step for none responsive iPhone.

You can learn the procedure in the support article I linked to below.

Force restart iPhone - Apple Support

Same story with my new iPhone 16. It has to be a flaw by Apple and IMHO, they should give us all some sort of credit so that we can turn these in earlier than we ordinarily would. This is beyond exasperating

I just bought my phone in November and I am experiencing this issue. I have tried 3 different wireless chargers and my iPhone charger. None seem to be charging my phone or at least that what it seems like since it isn't turning on. I have tried to force restart it several times and nothing. This is frustrating since I have barely had this phone for 2 months and it isn't cheap.

iPhone 16 pro max charged overnight while turned off. Used a different but compatible lead and wouldn’t turn on. Volume up and down quick tap and held power button sorted it. Sorted but disappointing and complex for someone who doesn’t look on YouTube for an answer. A phone of this level and pricing should be more full proof I would have thought.

Why are you turning it off to charge it in the first place? It is not necessary, nor even recommended the phone be powered off to charge. In fact, doing so, stops necessary background processes and prevents the normal backup of data to iCloud.

Why do you think it’s a bug, rather than a hardware problem with YOUR iPhone? I have no problem turning mine on if I turn it off, and apparently millions of other users don’t have a problem either, or they would be posting here. Have you had Apple Support evaluate your phone?

Having same start-up problem with an ipro 16 plus just purchased this week (February 4). Never had a problem like this with previous iPhones. Happens when I have turned off the phone and charged it overnight. Clearly a serious bug that Apple should have fixed by now. Hello, Apple, are you reading this and listening?
