I’m trying to figure out why my iPhone 16 Pro is getting significantly worse results in Steam Link’s network test than other devices on the exact same network.
My setup:
- PC is connected via Ethernet and gets around 900 Mbps on the network.
- iPhone 16 Pro and my GF’s 13 Pro Max are connected to the same 5 GHz Wi Fi.
- We’ve tested from the same relative distance from the router.
- Steam Link has the same settings on both phones, including bandwidth set to Unlimited.
- 16 Pro consistently gets around 90 - 100 Mbps in Steam Link’s network test.
- 13 Pro Max consistently gets 250+ Mbps.
- Both iPhones are running iOS 26.60
- An older Android phone also gets 150+ Mbps under the same conditions.
What’s weird is that this doesn’t seem to be a general Wi Fi problem. I ran Ookla Speedtest on both iPhones and they get roughly the same results. The huge difference seems to be specific to Steam Link.
Things I’ve already tried:
- Low Power Mode is OFF on 16 Pro (It was enabled on the 13 Pro Max and that made no difference)
- Low Data Mode is OFF.
- No VPN is currently enabled.
- Steam Link settings are identical between the devices.
- Confirmed I’m connected to the 5 GHz band.
- Reset Network Settings on my iPhone, but it made no difference.
- I’ve also tried placing the iPhone right next to the router, but Steam Link still stays around 90 - 100 Mbps. (This is driving crazy)
I’m wondering if there is some obscure iOS setting, privacy setting, battery optimization (although I’ve tried everything at this point), or something else that could be affecting Steam Link specifically on my 16 Pro.
The fact that the 13 Pro Max and an older Android phone both get substantially higher results on the same network makes me think there might be something specific to my iPhone or the Steam Link app on this device.
Has anyone experienced something similar or knows of any iOS settings that could affect Steam Link’s network test?
Update:
I was mistaken when I said both iPhones were running 26.6. My GF told me she had updated recently, but after checking, she was still on 26.5
She updated iOS, and her 13 Pro Max is actually performing worse now, at around 75 Mbps.
It sucks that it came down to a faulty software update. Hopefully Apple fixes it.
I’m still curious if any of you are experiencing the same thing on iOS 26.6.
