iPhone 17 Pro Max Whoa, overheated at just 10 min old. Did not expect to see that with a 17 PM "Charging on hold..."

[MareLuce]

One of the 3 reasons I upgraded from 16 Pro Max was to make this message stop. Gah!

More data:
- I was setting it up as a new iPhone. Since iOS 26 upgrade, I have not been able to reliably open Contacts or Messages on my 16 Pro Max. A solid white screen appears instead. Contacts and Messages are critical to me. I don't know what's caused that to happen. I had just started syncing my podcasts via Overcast app.
- Room was 73 degrees
- Yes it was in its silicone case.
Thank you for good points @dave006:

To answer @TracerAnalog and @gigapocket1
- Power adapter is an Apple 20 Watt USB-C I purchased (or was included) in 2020. I mark the year I start using any power plug on the bottom. (see pic in a new reply)

Is it in a case or in a warm room? The iPhone is quite busy when you first start if you have a lot of data to optimize.

Maybe it's cos Cosmic Orange is so hot already

Thoughts:

I haven't had this with a new iPhone, yet. I experienced all the time with my XS when iOS 18 first rolled out, but the problem resolved with subsequent OS updates.

I doubt the silicone case is the cause.

Ordinary room temperature that is tolerable to you won't be a cause, but sunlight falling on the device, even through a window, could be a factor (even with comfortable room temperature).

What I would be watching if it were me: Does the issue resolve itself after a day? Do you have any app using unusual amount of power, and does this resolve itself after a while? If the problem persists, does it resolve after the next OS update?

 

[gigapocket1]

What power brick are you using?

 

[zkap]

Depends on many factors in the environment, I wouldn't worry about it.

I thought they said that vapor chamber is the thing this time around

I think this may be an IOS26 issue. My 3rd gen iPad Pro has been getting this message ever since installing IOS26 last week. Never had it before.

 

[Lobwedgephil]

My 16PM did that all of the time, my 17PM has been cool besides the initial setup warmth, so far.

 

[madrigal77]

Mine did that too right after the data transfer. Organizing all the data makes it run hot. Once it was all done it's been fine. I wouldn't worry about it.

10 minutes old? It's probably downloading your stuff and indexing everything, while you're also charging it.

I wouldn't worry about unless it remains hot and not charging for a long time.

 

[TracerAnalog]

Also: which power brick?

Also: which power brick?

Power brick is a 20 Watt Apple USB-C charger from 2020. I always write on the bottom of a power brick or charger what year I start using it. (Does anyone else do this?)

Don't recall if I bought it separately or if it was included with an iPad or iPhone...

 

[S.B.G]

(Does anyone else do this?)

Nope, I don’t.

 

[MareLuce]

Nope, I don’t.

That means I'm nerdier than you. 😝😝😝

probably due to icloud backup, initial indexation and parallel charging. Out of curiosity, is there any good app that lets us know the iphone battery and CPU temp? I did not backup anything to my new phone, and it runs cool.
