iPhone 16 Pro not turning on

I had the same problem. I tried turning it on many times and it wouldn’t work. Fully charged, plugged in and the force restart with volume buttons / power didn’t work either. Eventually it turned on although I didn’t do anything different to the other times.

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.

Thanks for this, Mark. The piece that worked for me was the "quick" volume up, then down. After two quicks on the left side of the device, the right side button hold down produced the Apple logo in about 6 seconds.

Thank you. I know that I’m not speaking to Apple here but was venting as to the issue. Glad you haven’t had the same issue with your phones that the many posters on here are experiencing.

The phones we have had the issue with are IPhone 16. Not the pro.

So my iPhone had this issue when I first got it. I was directed to set charging to 80% and use only Apple certified OEM chargers. It worked fine until upgrading to 18.1.1 2 days ago. Went back into lockdown mode and took 45 minutes of attempts on reset. Finally it powered up when I did a reset start on the mag charger. Upon contacting Apple and being moved up to senior level advisor they had me keep charging max at 80% and take screenshots of charging screens before and after as well as confirm times of shutdown and turn on. They are having me forward the details to them for 3 days and engineers at Apple are involved. While the phone does restart normally the past 2 days it is charging to 100% (even though set to 80%) and the charging history is not updating….it still only says the phone was last charged 4 days ago and prior to the 18.1.1 update. It does not show any charging history since then - which is not the case. I would say that Apple knows they have a charging/software/firmware issue and is trying to get it fixed without replacing a lot of hardware. Since this is widespread with the iPhone 16 and not other models I would say there must be a hardware issue….and not on all iPhone 16s but on a growing number. They are to contact me again tomorrow to continue the research. I will update as I learn more!

I've had this issue all morning. I tried to force restart 50 - 100 times with no luck. The quick volume up by itself, then quick volume down by itself, then hold right side button by itself worked first time. Might be a coincidence, but it did work.

I have a brand new iPhone 16 Pro and am having the same problem as everyone. I am currently stuck on the 'hello' screen and the phone is quite hot. This is most disappointing for a phone that costs close to $2000. I have never had problems with any of my iPhones in the past. Hopefully this issue will be addressed. As it stands right now, I have a phone that I can't use. Frustrating to say the least.

There is simply no need to turn the phone off at night. I don't agree with whoever suggested you shouldn't charge the phone all night, EVERY night. It's impossible to overcharge an iPhone. And iPhone is specifically designed, with Optimized Charging enabled to charge up to a certain level, then stop charging, until it knows you will typically start using your phone, where it will charge it fully to be ready for a days use. The advice to NOT charge it all night goes completely against how Apple designed the phone to be charged. And personally, I have NEVER powered my phone off at night, but I do keep my phone on it's MagSafe charger all night, EVERY night. Battery Health has NEVER suffered from this as it is how Apple designed the charging system to work in the first place.

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

You last sentence is a guess at best and at worst, not a good one. Please don't make claims you can't backup with any tangible evidence. Sure, you may be having an issue, but that doesn't mean the vast majority of users are also have an issue. I've had no issues on either our 16 Pro or 16 Pro Max. I know several people with 16 Pro models and none of them are having issues.

I have a new iphone 16 pro max it would not start in the morning, after i turned it off the night before, finally got it going by plugging it into the computer. So I took it to Apple after having it for a month, they turned it off in store and could not restart it, so they replaced it with a new one, which was a real bore as we live a long way from a store, and the whole experiece takes a while.

Then today guess what its happened again. Nightmare. An expensive nightmare as these phones aren't cheap. This time i cant get it to work at all, any ideas?

I bought an iPhone 16 pro 4 days ago. This morning the screen in black. I tried all that support said to do and it still will not come on. All is updated. Is this a lemon phone. Will it be replaced for free????

Same here. I bought an iPhone 16 Pro 256GB off the Apple Website on Nov 28, 2024. This morning Dec 11, it would not power up after charging all night. As I placed it on the wireless charger last night I turned it off while charging because I did not want it on all night. In the morning it would not power up.. I placed it again on the wireless charger and it would not turn on. I tried all the power up sequences with the volume control key plays ..but no luck. I left it with the USB cable and charger plugged in and decided to enter my story on this discussion board ..but two factor identification was needed. For some reason or other when I made the two factor identification request the iPhone suddenly came to life displaying my two factor identification number. I am almost afraid to power it down again.

Same🤔 my iPhone 16 Pro Max turned itself off and it took almost an hour to get it to turn back on. Quick up volume and quick down button then hold right button for several minutes. So alarming. Too expensive and no bug fix to my knowledge! 🤯😤😡🤬
