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.
Worst iPhone ever released. Even after multiple updates still overheating and runs RIDICULOUSLY SLOW ALL THE TIME. I have done all settings adjustments listed to increase speed but on WiFi it will barely load a webpage half the time and forget streaming a video. Won’t even load ESPN app. Wish I had never purchased. Still inside return window so probably going to try and return for a 14. My wife’s phone has none of these issues
I’m not sure how adjusting settings for Safari would affect WiFi speeds on my phone in general but I gave you the benefit of the doubt and tried it. Maybe this helps in the Safari app itself but using chrome or running a speed test still has the same resulting slow speed
I don’t know how you found this seemingly obscure setting or how anything to do with Safari affects WiFi speed, but I toggled this off on my 15 Pro and the difference was indeed night and day. From d/l around 114 Mbps to 457Mbps, and upload from less than 1 to over 40 Mbps, so thanks for that! Cheers.
My MU-MIMO setting is enabled on my netgear RAX45 router and I am getting exactly the same results on my iphone 15 ProMax as I am wired from my PC. Perhaps it is an incompatibility with your router not the phone?
933Mbps down
868Mbps up.
Enabling/disabling iCloud private relay made little to no difference.
Each Apple product I have is less capable than with less useful features than previous Apple products. I have this issue with my $1k iPhone 15pro as well. I wish had kept the 12 pro which worked just fine. The latests OS updates across the board were the worst I’ve seen in a long time. That said, I eventually did find a fix… I gave the device to my niece and bought a different product / brand. Now I have none of these issues. That was the only fix that worked for me.
I 100% agree with you. I am doing the same thing so frustrated that I just don’t even try to access the website. I went from a basic iPhone to the iPhone 15 and I am very very very disappointed. Maybe I should change to an android, my son says they’re great.
Is Apple going to do something about this??? I upgraded from IPhone 10 to 15 and it straight up feels like a downgrade with this WiFi issue. I disconnect and immediately get better connection. I have the highest internet speed available, it’s not my WiFi.
Yup it happens on every router/ wifi connection, so it’s not the router/modem. Hopefully apple will update something on it. Its horrible. Bout ready to toss this piece of **** in the garbage.
Have exactly the same issue
My Download Speed is Fine but my YouTube Videos are loading years and get stuck throughout the Videos….
Hello JMAN712,
Thanks for the update 😀
This didn't change speeds for me
You are a superstar!
My IPHONE 15 PRO MAX WIFI is painfully slow as well, turned off Cellular to try and make it faster along with several resets. This phone is trash. I upgraded my 13 and just want it back :(
Mine too. It was slow out of the box. Mine is not even a week in use.
iPhone 15 WiFi painfully slow.
