iPhone 16 Pro Max Not Charging-USB

My iPhone 16 pro max does not charge with USB but does with MagSafe. I get this error:


"panicString" : "panic(cpu 1 caller 0xfffffff04d8a8b44): \"AppleGen3SPMIController[nub-spmi-a0]: Request\/Response header mismatch: Req: 0x9008C80 Rsp: 0xC60 cmd: 0x7\nBad Response Count: 0\nFault queue circular buffer


does this mean the logic board is bad or can changing the USB port suffice for resolution? I need to update to iOS and cannot over wireless so I need USB to achieve and fix Face ID etc.

iPhone 16 Pro Max, iOS 18

Logic boards Apple will not replace they will have you replace the entire phone


This is not correct.


I need to know if the usb port replacement.....


Apple will not repair or replace just the USB port if that is what you are thinking. If the USB port has failed, things are going to be a lot more complicated in terms of repair. You can confirm this when you take the phone in to the Apple Store / Genius bar or to an authorized Apple service shop.


You can find a list of authorized shops in your area using this link:


Find Locations


I will need a more specialized answer with someone who is not a normal user.


Then, you are on the wrong site. This is a user-to-user site. We are all users here. This was explained to you in the Terms of Use Agreement.....which you signed to use this site.


Apple is not here. They will not see your post or reply. Take your iPhone in to an authorized shop if you want to make any progress.

A normal user like me does not want to know what these analytics/diagnostic data mean.

These are meant for diagnosis when the iPhone goes for service or repair at the Apple Authorised Service Center.


Check for Conflicting Apps: If the issue started recently after installing a new app, try uninstalling it and see if the problem persists.


While I wouldn't personally act on the Analytics report you provided, I encourage you to explore it for potential improvements. Taking this step is unlikely to have negative consequences and may boost your confidence. --> General Troubleshooting iPhone Issues: St… - Apple Community

Much appreciated. Me on the other hand. I am IT and I have an LLC and some on computers, laptops, tablets and phones. So for me I am inclined to learn more as I support these devices. Logic boards Apple will not replace they will have you replace the entire phone. This device has a recent battery and screen replacement and need to calibrate the hardware and cannot since the iOS update will not update and the usb is now out. I need to know if the usb port replacement would work or if this requires a more specialized logic board inspection and repair. The cable for power used is an official Apple charging cable that works on my other iPhones. I do appreciate the time you took to attempt to answer my question however I will need a more specialized answer with someone who is not a normal user.

I appreciate your feedback in my experience so far I was told by Apple to replace the phone they do not work on logic boards so in my experience my statement is correct. I came to this community in hopes that others have experience working on iPhone as technicians not necessarily looking for an Apple rep so in your opinion I’m on the wrong site in my experience I have found others like me in these types of groups. So again your opinion is appreciated but I don’t think it’s relevant to me.

Your one-time experience does not entitle you to make a blanket statement about Apple which is not correct.


Depending on the age of the iPhone, the cost of replacing the logic board might be prohibitive and there may have been other items that needed attention.


Rather than simply saying "replace the phone", they could have said something like "the money might be better spent on a new phone".


It is possible to replace a logic board in any iPhone that I've ever seen. I've had a logic board replaced in the past and we speak with users all the time on this site who have done the same.


I came to this community in hopes that others have experience working on iPhone as technicians.....


This is a site for users......not professional technicians. Sure, it is possible that a technician might post, but in 18 years on this support site.....I can say that this is a rare occurrence.


Speaking of relevance, this site is not relevant for you, but you never know. Maybe someone will post to tell you exactly what you have already decided will be the answer.


Good luck.

Obviously not. There is a way to communicate without being sarcastic and snarky. You’re quite rude and you can close out this discussion because whatever has you so bothered about my post has you lashing out for no apparent reason. Others have posted diagnostic codes in this community and my blanket statement as you call it was not misleading as I actually spoke to Apple. I’m not going to go back and forth with you on it. I’ll go to a community that actually wants to discuss things in lieu of being rude to make themselves feel better. Have a nice day Bob but your delivery of your message was not needed, not purposeful and you can take the attitude somewhere else.
