Upgraded to an iPhone15 from an iPhone X (yes, really) and ever since the wifi connection is awful. Pages that loaded perfectly on the same WiFi with my iPhone X, will load very slow if at all. More often than not, I end up getting frustrated with the slowness that I just exit out of the app or site. It’s really bad and I’m not sure if this is a settings problem or if my WiFi chip might be defective??
iPhone 15 Pro Max, iOS 17
I believe I've figured it out. If you have iCloud+, there is an option that I did add without realizing it when I first got the phone or updated it. It's not displayed as a VPN or in the VPN setting. That's why I think it's been so hard to figure out. It's under Settings > iCloud > iCloud+ > Private Relay > Off. Restart your phone after turning it off and my download speed went from 97mbps to 496mbps, as it should since I have a download speed of up to 1200mbps from my home service. I hope this helps. It has been driving me crazy since my 11-year-old computer was downloading so much faster compared to my new iPhone 15 Pro.
And restart your iPhone. Also, mine appeared to already be set to not connect, but it was also using my password manager VPN. Dashlane doesn’t have this setting, so I changed it to another VPN and then set that one to not connect on demand. Restarted the phone and the speed is back to normal.
Same problem and the solution was adjusting the router. The network was mistakenly set at 2.4 GHz. When I reset to 5.0GHz the problem was solved.
Turn off 160 MHz on your router.
My phone's wifi speed is back.
iPhone 15 pro max 17.3
OK everyone, I tried every suggestion in this post. I finally though fixed it.
go to Settings
click Wi-fi
Choose the network you are using and hit the blue i circle on the right
If you have Private Wi-fi Address "on", shut it off...wait a minute, click it back on.
BOOM - worked amazing for a while, then slowly it crept back to crap again.
Back to the drawing board.

Next - I reset my network settings. It didn't fix it.
Finally I went into the blue i on my wifi again and shut off the Private network and left it off. So far so good.
Thanks but I’m familiar with the difference between cellular and WiFi. Here’s a better diagnosis:
clearly the phone is the issue like the other 800 people here.
Temporary fix. Issue resumed after leaving my house and returning to WiFi range.
absolutely horrendous performance. Cannot even load a song in apple music.
I'm concerned that my Amazon Echo has better streaming performance than my 1500$ iPhone.
Hello,
If it worked at your house, but not when you left it, it could be an issue with cellular data. See this:
Use cellular data on your iPhone or iPad
View or change cellular data settings on iPhone
Good luck.
Same thing is happening to me, on both the iPhone 15 pro max and an iPhone XR so this is definitely a software thing and not a hardware thing. For the 15, WiFi only = 36Mbps, WiFi + data = 163 Mbps, data only 350 Mbps. The XR’s data only is slower due to not having 5G but it paints a similar picture. Eagerly awaiting an update that fixes this because we shouldn’t have to change settings on our router based on a software update on our phone 🤔

I have similar experiences. I have tried a number of the suggestions in this discussion, but nothing has really helped. Apps are often very slow (crazy slow) and most of the time are unusable. The only "fix" is restarting my iphone 15 pro max. I have had iphones for years and have never had to restart them as frequently. With my older iphones, I might restart every month or two. With the 15, I have to restart it at least a couple of times per week, just to get some apps to work.
We are an Apple house (9 devices) and our experience is that each new addition is a little more expensive than the last, and a little more problematic. We aren't at the point of abandoning apple yet, but we are getting there.
I just up graded to the 15 pro lase week and my wife to the 15 pro max this week and the down load speed is so slow on wifi that we have to stay on data.
is there a update coming?
Mine was already off and I still have the problem.
My issue is when wifi is on web pages pretty much won't totally load no matter who's house or if public or private places, but if I turn off wifi the page loads quickly. Video streams from any platform play fine on wifi download speeds when checked on my iphone Pro Max are 97-98 MB down and about 2-3 MB up. Using the web browsers just sucks on wifi.
Unfortunately many will not have the option to disable this feature if they have a modern, provider-issued modem. I’m glad you found a solution.
I’m currently testing a workaround of turning off 6e capabilities after connecting to my WiFi. If anyone else would like to test this with their 6e capable router please let me know.
I purchased 2 new Titanium 256 pro phones because my husband I always get new phones together and he lost his phone on the highway. Long story short…. I hate this 15 titanium. I have more than enough space on the new phone. However, searching google, pullubg up photos at google documents is an unbelievably slow. Also, when I am watching a you tube video is so slow to play and pauses and even stops. I hate this iPhone phone product. I am a iphon used with 6 devices but this Titanium is not worth the investment and not a reflection of typical apple products. Hate it and ready to change.
I saw that bit about VPN & private relay in earlier responses but my private relay was turned off by default and I’m not using VPN so while those may also be issues they’re separate from whatever is plaguing my phones.
iPhone 15 WiFi painfully slow.
