iPhone 16 Pro not turning on

Did the side by side….the only thing that seems to keep mine going without reset/restart is to keep the charge at 90% or lower. Also not using OEM Apple MagSafe charger….as long as below 90% and using USB-C or a non-OEM (not Apple) wireless charger it works normally. I am amazed Apple isn’t doing something about this issue…at least they aren’t addressing it publicly!

Just had to do a forced restart on my iPhone 16 pro max, it was on charge via cable and when I went to turn it on it wouldn’t (so I panicked first of all as I’ve got an important phone call due this morning) then I remembered about the forced restart button trick but is this a problem with my phone or a problem with the IOS which is the latest update to date version, I forgot to say I had this happen once before with a brand new iPhone (not sure which one though) and after that happened once it didn’t happen again

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

Happened to me too just this morning. Very frustrating. Tried the quick volume up then volume down then side button holds and it worked after an hour. I had also put my phone on charge even though my battery was above 50% before this all happened…

Charged new iPhone 16 Pro Max overnight and now I’m unable to turn it on! Been trying for nearly an hour - appalling, I hope this gets sorted ASAP. I can see many other users experiencing difficulties, surely this should not happen with new equipment!

"They said the battery was completely swelled up and melting the hardware! "

This makes perfect sense! Apple does not have a charger included with the new phone. Users are using whatever

USB-C chargers they can find. The phone can get overcharged as a result.

Lowering the charging limit to 80% or 90% should avoid over charging issue. If the phone is turned off, it cannot enforce that limit and it will go to 100%.

All my past iPhones I have turned off at night. A while back I remember reading something saying it’s good for the phone. I did some research and there does seem like some merit to it being bad. Though this probably has nothing to do with it being bad for the phone. Also there are safety measures regarding charging, even over night. It cuts it off when full. Also, charging over night, again even if it was bad for the phone. Wouldn’t affect it not turning on.

Turning a phone on and off doesn’t necessarily strain the processor directly but rather the entire startup sequence. Here’s why it can impact the processor and other components:

1. Increased Power Demand: During startup, the processor and other parts like RAM, storage, and wireless radios work harder to initialize the system, load all necessary processes, and establish network connections. This initial surge in activity demands more power than regular standby or idle mode.

2. Thermal Stress: When the processor moves from a cool, powered-off state to a high-activity state, there’s a quick temperature change. This thermal cycling can, over time, contribute to wear on the delicate silicon components, as they expand and contract slightly with temperature changes.

3. Component Aging: Every power cycle contributes to the gradual aging of microchips and other components. Silicon-based processors can withstand many power cycles, but more frequent on-off cycles can, in theory, shorten their lifespan marginally.

That said, modern smartphones are designed to handle these power cycles with minimal wear, so the effect is small. Regular restarts are generally safe, but completely powering down every night might cause slightly more strain over many years compared to low-power modes or sleep modes.

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.

Mine also won't switch on and this is the second time this has happened. I have tried all the tips below and it still won't switch on - any other ideas? I can't get to an apple shop until the weekend.Thanks

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!

I had the problem with my 16 and now a week or so later my husband had the same problem this morning. It took him several times trying the hard reset before turning on. Apple needs to fix this. I took mine in to the Apple store when it wouldn’t go on and the lady there that fixed it didn’t mention the hard reset or that this is evidently a problem but acted more like I just didn’t hold the power button long enough, although I had the phone for 2 weeks with no problem turning it on. I really do know how to turn the phone on.

Come on Apple, fix it!

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.

You're welcome. Have you updated your iPhone to iOS 18.1, which was released over a week ago?

No, I never turn my phone off at night. There's no reason to turn it off, with the exception of an occasional restart if needed. When I put my iPhone on its charger at night, it is fully powered on and connected to Wifi, so it will automatically backup to iCloud while I sleep. That is what Apple recommends.

Well just got my son and iPhone 16 and had it for one day and it isn’t starting up! So frustrating brand new phone and so far the worst experience with this phone. Maybe a recall should be in the works. Seeing this happening to everyone with their iPhone 16 pro. Ugh .shouldn’t have gotten this new model . Very frustrated!
