I wouldn’t expect that monitor to follow standards either 
I hope Framework finds a resolution that helps you guys, but saying all devices are effected is false. None of the phones in my house have this problem when plugged into the Framework16. All of them connect, start charging off the laptop, and allow me to access their files. No cycling of roles, disconnecting, or any of that.
Update:
I demoed the issue when I was in Ubuntu Summit in The Hague where Framework has a booth over there. Their firmware developer later replied to me that this issue is still under investigation.
And there are two things I got from their developer:
Please correct me if I’m wrong about this.
A year later…and we’re already with iPhone 16.
As much as the chassis and other components might have a 10-year+ life… The usefulness and price premium on ‘current’ tech does somewhat, indirectly, demand functional issues to be resolved sooner rather than later, no?
How many 1-year-and-unresolved issues are people willing to put up with?
Well of course not, the usbC expansion cards are just “wires” to extend them to the edge of the laptop. There is no smarts in them.
I mean, at least Framework doesn’t go Apple by using Vendor-defined Messages in PD protocol to expose some features:
Btw, this issue does not happen on Intel Core Ultra Series 1 systems.
AFAIK, it doesn’t happen on any Intel system. Every complaint I’ve read used an AMD system.
This issue, albeit seemingly one in the same, combined with being unable to use external USB C one wire powered “portable monitors” is nearly a deal breaker at this point. Definitely will be re-evaluating what I am doing next hardware upgrade time which is unfortunate because I want to love everything about FW16. 
This might not be enough to make it less of a deal breaker for you, but there are portable monitors that work fine with AMD FW over a single USB C.
Is there a list compiled somewhere of definitive “yes” screens? It seems like some decision alluded to that the 2.5k or 2560/1600 resolution screens were most successfully working?
Sorry for the late response. This portable monitor that I bought works perfectly for my Framework.
I don’t know if you still have your Framework 16, but I would advise trying to get a replacement one because it seems defective. If you did this already, then, unfortunately, all you can hope for is a firmware update, or late refund??
Why are we talking about portable screens in a thread about iPhone compatibility?
I think we are still on topic about USB PD issue in general…
Hi, just to clarify the iPhone 15 problem:
When you plug the iPhone 15 into a USB-C port of the FW13 AMD it has the described problem.
Does it have a problem with any non-AMD FW13 ?
When you plug the same iPhone 15 into a USB-A port of a FW13 AMD it works.
Is that a good summary? Note: I don’t have an iPhone.
So, there is a work around for the problem?
The problem only occurs in AMD Framework laptops.
Since USB-A doesn’t have PD protocol negotiation it can (and does) workaround the problem.
After owning a FW 13" AMD for a few months, I’ve just attempted to charge my iPhone 15, and have run into the endless “Do you trust this computer?” loop. Reading the above, it appears to be a Framework hardware problem.
Is there any progress or resolution?
I have a FW13 with a Ryzen 7 7840U.
I’ve had an iPhone 16 Pro Max for the past 2 weeks, and android phones before that.
I’m also experiencing this issue only with the iPhone. I’ve tried all ports and USB-C to USB-C and USB-A to USB-C cables. With the USB-A cable it starts charging and then disconnects almost instantly without ever reconnecting, even if I unplug and re-plug the cable.
With USB-C to USB-C I get a constant loop of connecting and disconnecting.
Just to be sure, I tried the iPhone on other laptops with different CPUs - i5-7300U, i5-8350U, i7-11800H, Ryzen 7 8845HS.
I’m sad because I wanted to transfer some photos off the phone to my FW laptop, but I’m unable to.
I hope we get a firmware fix soon.
Why can’t you plug the phone in through a usb hub to the laptop? Does that not work either?
I got the same idea today so I went and bought a cheap Hama dongle. Just got back home, plugged it in, plugged a USB-A to USB-C cable in the dongle and bam! It seems to be working just fine.
It’s a workaround I’m willing to use and won’t be complaining more.
Yep. If anyone else missed it, a USB-A expansion card works, or a USB-C to USB-A adapter + USB-A to USB-C cable. At least iirc it’s been reported a few times to be zero issue. Iphones only glitch when it USB-C straight through.
