Apple apparently acknowledged the NFC chip problem and plans a (software?) fix later this year.

Rare for Apple to actually admit issues like this as well, and they have one of the world's best legal teams. Not a decision made lightly on their end, I'm sure. |

It's interesting that they think they can fix this in software. I wonder if there is more to it than just the phone overheating on the charger. I've seen that with several iPhone versions before 15. IIUC, lots of BMWs have an NFC radio in the tray even if they don't have wireless charging. I'd be interested to hear if anyone had the same issue just using the phone key function but not charging. |

It's not surprising to me that this is a software issue. I am a computer hardware hobbyist/geek and I would guess this is some sort of voltage regulation issue between the phone and the wireless charger. Messing with voltage is a great way to fry chips. But - that's 100% speculation with little evidence. Otherwise, just happy to see someone's owning it. Not surprised it's Apple. |

The thermal dynamics of the phone on a wireless charger in a vehicle is much different than on a desk or nightstand and I suspect Apple has not adequately taken this into account. With the wireless charger situated such that air circulation (and thus heat dissipation) is poor, keeping the heat under control while maintaining charge on a phone that may be constantly downloading data (music, navigation) over power hungry 5G is a tall order. I regularly experience situations where the phone has turned off wireless charging due to exceeding thermal limits. I suspect the software fix may be to decrease the maximum thermal limit, at the cost of being unable to maintain the charge on the phone while on a wireless charger. I wouldn't be surprised if Apple also provides or updates guidance on wireless charger specifications to address heat dissipation requirements. Last edited by StanDiego; 10-26-2023 at 12:33 PM.. |

What makes me think that it's something more than thermals is that very fact that most chips are designed to shut off at high temps. Usually hitting thermal limits doesn't fry chips, it just turns them off. These chips, if they truly are being physically damaged in some way, has to be something on top - current, voltage, otherwise. Either way, glad someone is stepping up and coming together with a fix. Also, I might try out one of those little fans advertised in another thread! |

I’d actually like a mount with the magnetic wireless charger. It works really well, with no excessive heat and a fast charge. I’m not sure where a mount could go, though, without it being messy.

I upgraded to the IOS 17.2 public beta yesterday but release notes don't mention anything about a fix for this (yet).

Sounds like the latest patch is taking care of the issue:

"It is normal for your phone to heat up while charging, especially if it supports fast charging or super fast charging, as the current and voltage are higher when compared with normal charging. If you are charging your phone wirelessly, your phone may generate heat due to energy loss during wireless data transmission. This is normal and does not indicate an issue with your phone." The real question is who will first volunteer as tribute to try this out? LOL. I've already got a replacement because of it. So I'm going to hang back and wait for some testimonials. |
