Anyone else having this issue? I can’t charge my phone with a MagSafe charger using the any of the USB-C ports at the back of the ASD.
I can charge my iPad and a MagSafe Duo Charger using the usb-c ports but using a single MagSafe charger for my phone or MagSafe AirPods Pro doesn’t work. The MagSafe charger is fine as it works using a usb-c power brick plugged in to the wall but not the USB-C ports at the back of the ASD. I can also charge my phone using a lightning cable from the studio display.
What is even more strange is that if I disconnect the thunderbolt cable from my MacBook, the MagSafe charger then works.
So in summary, all devices including phone, iPad, AirPods, MagSafe Duo will charge from the usb-c ports except for a solo MagSafe charger…..but it will work if I disconnect the tb cable from my MacBook.
Firmware issue with the MagSafe charger perhaps? Or maybe a TB cable issue?

Same issue here. My MagSafe charger is connected to my Studio Display. When I place my phone on it, it WILL begin to charge and then eventually stop (before the phone is charged). Once it has stopped it usually won't charge anything at that point. Seems like some sort of dodgy power management profile for the Studio Display?

Considering the Studio Display supports 96w charging to the host device, I imagine none of the 3 USB-C ports supply more than ~10w of power delivery when connected to a host.
 
Studio Display + MagSafe (4th peripherals) -> Not Charge

No matter which port, which other 3 peripheral
 
The ports don’t provide enough power. As I recall you need a 20W power supply for the MagSafe charger.

Great so we have a $1500+ monitor with a A13 inside that, even though these are absolutely supported by its internal hardware:

1) Won't provide AirPlay functionality
2) Won't provide Apple TV functionality
3) Won't properly charge an iPhone via its highly touted Magsafe functionality through any of its USB ports

This is a joke right? Apple isn't actually this inept.

Man, I can't charge my Tesla car with the Apple Studio Display too using the USB ports. What a garbage monitor.

And what you need AirPlay and Apple TV functionality for when the Apple Studio Display is intended to be used with a Mac that has Airplay and Apple TV already.

Solid straw man argument there.

So why did we pay for an A13 and 64gb of storage? What functionality is that providing us that thus prevents the monitor from charging an iPhone properly? I'll leave the Apple TV on the side because I agree that its not a common use case but the point remains we have a 27" iPad on our desk that intentionally does not utilize its hardware to the benefit of its customers.

Is not the Apple philosophy "1 cable"? Should I be thanking them for requiring that I plug an entire separate cable into my Mac / a second power cord into the wall just to keep my iPhone charged?
 
That's right, a USB C to lightning - I'm seeing, via coconutBattery that I'm getting about max 8w out to my iPhone.

Despite this, I am happy that the Display has reduced the cables on my desk by 2-3x.

Likely because that was the cheapest A13 SoC they had available. Either because the 64GB design was cheaper than retooling for a 32GB (or some other capacity) or because the volume of 64GB models made it more cost-effective than a smaller run of 32GB units.

There are too many smart people at Apple. They knew their design of the display wouldn't put out 20w on the USB-C ports to support a MagSafe charger. They just didn't care.

What are you complaining about? Is the Apple Studio Display marketed as a MagSafe charger via it's USB-C port? No it is not. Just plug a USB-C to lightning cable to your iPhone and be done with it.

And there is no need to put Apple TV and AirPlay on the side, because it's already there if you connect a Mac to it, just like what the Apple Studio Display is designed for. You are not missing these features.

And the A13 is for Siri, Spatial Audio and the Center Stage. Everybody should know this by now.
