Apologies if this has been talked about already....

I am seeing serious issues on iOS 11 (latest version) with WiFi download speeds. I also saw this on previous iOS 11 versions. I have gigabit Fios, has been tested numerous times on the wired connection with multiple devices and is running at the correct speed. iPads in the house pull about 500 down and 500 up....which is fine given all the potential issues WiFi can have. My iPhone X however can upload in the 500 range but over and over pulls 100 or less down. This has been tested with a Fios Actiontec router, a latest version AirPort Extreme, and a Synology 2600....all with up to date firmware. All were placed in the same spot, set up independently, all with a dedicated connection from the ONT. I am confident it is the iPhone that is the problem, I will be testing tonight with another iPad and with an iPhone 8 (all on iOS 11) and will report what they show as well.

Edit 1: my iPhone X test were run before and after resetting all network settings on iPhone
 
You should be able to do at least this, if not faster.

Municipal 1g/1g fiber. Ubiquiti gateway/AP’s.

IPhone does run comparatively slow to ipads and laptops which run over 400 breaking 500. But its not concerning to me.

I am wondering if it is something wrong with my hardware, which is why I want to test the 8. Despite apple’s lack of specifics on WiFi specs, it appears the 8 and the x both manage 2x2 MIMO, so theoretically they should run similar download speeds. (I am well aware a number of factors can affect speed and they are different sets of hardware, just looking for approximately similar performance).
 
Well, sadly it’s the same on my girlfriends iPhone 8 about 50-100 at best. Looking more and more like iOS is the problem.
 
8 Plus here. 11.2.2. Pull 350-450 up and down. Average is about 400 for both.
 
You are testing your ISP speed. If you want to test wifi throughput you'll need an app like wifi sweetspots. This will test just the connection of your phone to the router, not the bottleneck of the ISP.

Its also a good app for locating dead zones and finding better spots for router placement.

Best I've seen my iPhone 6S get was 1.1Gb/s to an xfinity router of all things.

Thats outside the realm of physcial possibility. Sounds like an endorsement that the app is a hoax.
 
I think I got it, annoyed I didn’t think of this sooner. My speed test app automatically picks the server to bounce the test off of, but my computer doesn’t. All I needed to do was manually change the servers I tested against and after trying a few it turns out most of them are in the 500/500 range, whereas the one the the Speedtest automatically picked was still only 100 or less down. So it would appear that the issue wasn’t my phone or iOS but rather the speed test app itself and the manner in which it chooses servers.

What is out of the realm of physical possibility?

I just mentioned a app, you can use any Wi-Fi speed app of your choice
 
Fortunate to have 1 GB/s municipal fiber here. Airport Extreme router. With my iPhone 8 I typically get 350 MB/s down and 700 up.
