iPhone 16 Pro not turning on

Same here. The only thing tech support told me is to reduce the battery charging to 80% and therefore not able to use optimized battery charging. Also to only use the supplied USB-C cable NOT the Apple MagSafe I have used for years and try that….either way it’s not good! As you say these are expensive phones.

looks like you have the opposite problem to me. Mine charges on both but if I use the wireless I have to do the vol up/down reset…and at that very slow to start. Also can’t charge to 100% or I also need to do reset start. Hopefully Apple is reading these posts and working on a fix….seems like a spreading problem!

So I have had this problem since day 1…but only when I use an apple OEM MagSafe and the phone is set to charge over 80%. When it won’t start I have to do volume up volume down and side button (hold until the apple logo comes on). It works normally charging on USB-C (although have not tried at 100%, only charging to 80% or 90%). I works on a third party wireless charger (although when set to 90% it charged to 100%!). I have spoken with apple support both level 1 and subsequently level 2 supervisor and the only answer they have is use the USB-c provided and do not set over 80%. My opinion is this is a glitch and apple has yet to figure out a fix. I am lucky in that I have always managed to reset and get it operational…it’s disappointing that Apple hasn’t yet stated they are working on the problem and indicated it will be covered if hardware or corrected by a future update. Last note…all the chargers and cables I have used work fine on my wife’s 13 mini and worked great for years on my 13 pro.

Quickly press volume up then volume down then press and hold side button until the apple logo comes up…then release. If that doesn’t work do the same thing plugged in with the USB-C charger. That is straight from Apple tech support….the. As a safeguard set the charge to less than 100% before charging next time.

Same here. 16 pro max wire charged overnight. Dead as can be. Nothing worked to resuscitate the phone. Made an appoint with the Genius Bar as a final resort.

I also have the iPhone 16. Samen thing happened twice, but I managed to get resuscitatie it through the DFU-procedure.

I have bought several iPhones throughout the years, but this never happened to me before.

I posted a message on the issues discussed here. I also tried to recussitate the 16 pro max applying the wireless DFU-procedure by putting my (working) iPhone 16 next the (not working) iPhone 16 pro max. Helas, that did not work either.

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

I took my phone to the Apple Store and the best they could save was delete and reinstall the operating system. That is to say erase your phone completely and reinstall the operating system like you have a new phone. I haven’t gotten around to that because it’s such a labor-intensive pain in the butt. I did Apple help via chat. They had nothing. Has happened three times and on the third time I went into the Apple Store and essentially they had nothing.

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!

This is the worst “upgrade” I’ve ever experienced! Every 2 years I upgrade and I’ve never had issues like I’m having now. This is a brand new phone and it’s acting like an old one, this is unacceptable and Apple should be ashamed for putting out a product with this many issues. First I had issues setting it up with iCloud so I did side by side and that worked. Now this power up issue has revealed itself. I wasn’t charging my phone when it happened, it just shut off with the phone screen going instantly black. It wasn’t dead. I’ve tried resetting it and it isn’t turning on. I tried charging it using MagSafe and usb c, nothing happens. Paid over $1000 for a POS phone. Thinking about switching to Samsung.

"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%.
