I just did an internet speed test, my Iphone 12 now just have download speed of 3.4 Mbps after updating to IOS 17.1
iPhone XS, iOS 15
After updating 17.1.1 my iphone 13’s wifi speed has slowed down drastically. Youtube, facebook and even the safari browser is taking long time to load and display content. Because of the lag, the phone is continuously switching to mobile data from wifi. Just to clarify my wifi is working fine with other devices. Please fix this as we expect premium products and services from apple
im having the same internet issues on my phone and i tried doing that, but apparently you only get the private relay option if you have an icloud subscription and i don’t. this thing is rly annoying me lol i just want my internet to work

Been there. Done that.
Both of my replies are simplistic and for starters. Having no success, move a bit forward with the following reply by @iagastya. Any success?

Troubleshooting Lagging Wifi on an iPhone:
If iPhone WiFi is slow, then here are some things to consider...
A. Disable a VPN:
Are you using a VPN? If so, disable it.
B. Clear Space:
System resources may be swollen up. So, clear space. See my two User Tips:
C. Clear the Temporary Internet Files:
D. Force Close All Apps:
An app may not be responding. So, close all apps. Hold you finger down on the Bottom-left cornet. As you swipe to the top-left corner, the apps will pop up. Then, close all of these open apps, by sweeping up quickly for all apps.
I’m also having this issue on 17.3.1 with my iPhone 15 Pro. Knowing that I hadn’t turned on my current gen iPad Mini in awhile I booted it up and ran a test since it was on 17.2. It got 500mbps. I then updated the iPad to 17.4.1. My iPad now only gets 40mpbs down. I took screen recordings of both of those runs. In both cases the devices have iCloud relay off, and I disabled background app refresh for all apps to see if that mattered. No change for either. Resetting network settings also had no effect. My work laptop and phone(Windows and Android), both easily get 800-900mbps down on the same WiFi network. My iPhone 15 Pro also gets 900mbps down from its cellular connection through t-mobile. The issue only presents on my iOS devices with current versions of iOS, and only on WiFi.
I have same issue, just updated to 17.3.1 and still the internet is slow either on mobile network and wifi ( work and home)…
Similar problems and all the usual fixes do not help. What has helped is turning off the new “Private Relay” feature. This seems to produce consistently better results by about two orders of magnitude. iPad and MacBook Pro and iMac all absolutely great. iPhones just a complete disaster.
When Private Relay is off I get between 40 and 300 Mb/s. When Private Relay is switched on I am getting between 1 and 30 Mb/s. Would be interesting to know if others get similar results.
That text book troubleshooting, this has to do with IOS 17! After this update surfing the net lagged big time get a message sometimes saying reduce protections to load page or something.

I was very sceptical about doing any further upgrades until this week when I had to make a decision about upgrading after having major issues after my last upgrade slowing down my iPhone 13 Pro, I did everything suggested to help speed it up.
I now have done the upgrade 17.4 and fine my iPhone has the speed back. They have obviously rectified the previous issues, with new additions which I’ve not explored yet, things seem to be getting brighter.
I just got on the phone with Apple and he had me check my battery.
Settings > Battery > Battery Health & Charging
It shows my battery is significantly degraded.
He suggested this might be the problem and that IOS 17 put a greater strain on the old battery causing the phone to slow down.
I'm going to get a new battery installed ($90) to see if that fixes the problem.
terrible it’s like i’m on 3g now or E lol
I rarely use WiFi, but it is still slowing down my iphone 14. I have to go to settings and turn off WiFi (even though I’m not using it) to be able to do anything online. Then when I shut it off, it says “turning off WiFi until tomorrow”. But a few hours later WiFi will turn itself back on and aI will be lagging again. Beyond frustrating!
This is a user forum. No one here is getting paid. On the other hand, some very experienced folks (not me) take the time to help out. Apple only monitors this forum for violations of the terms of use, as far as I can tell. If you want Apple Support staff, go to the Support Page and scroll down to Get Support:
I’ve the 13 pro as well, doing exactly the same why haven’t Apple sorted this software problem I want to take my software back before updating to the latest update.
It has slowed down the phone dramatically. What are you doing about it?
Only wanted to note that on 17.2.1, while I can run a speed test and am doing fine, I'm getting super lagged push notifications and app updates. E.g. texts from the past several hours at the same time as a flood of ring notifications, amazon notifications, etc. Am on a 15 pro.
Same here. Iphone 12 WiFi is miserably slow after updating. All of my other devices are in the rage of 1gig up and down which is my ISP speed, but my Iphone is about 20 up and 10 down. I've never seen any other device that has slower download speed than upload speed. Please fix this issue!
Internet speed slow down after IOS 17.1 update
