iPhone Xs wifi slow (half the speed of iPhone8)

I just got the iPhone Xs and noticed the wifi was slow. I checked this versus my iPhone 8 and it's constantly half the speed using various apps like WiFi Sweet Spots or iPerf. It's also noticeable loading content from my local network too. What's going on?


I've tried both 5ghz and 2.4ghz, rebooted router, verified latest router firmware, rebooted phone, reset network settings on the phone, I don't have wifi assist on, disabled bluetooth all without any change. It's always about half the speed of the iPhone8.


The only time it seems close is if I'm literally standing right next to the router. Else if I'm a couple feet away, the Xs drops to half the speed.

iPhone Xs, iOS 12

Same here. My WiFi speed seems to cap at 5mb/s, my SO also have a XS Max but haven’t updated it to 12.0.1 and that phone is doing 144mb/s at the moment. Usually when this happens I can just normally restart the iPhone normally and it works for a couple of days, but today it’s just gone downhill. I’ve restarted it like three or four times and it’s still stuck on slow speeds. I didn’t notice this issue before 12.0.1, maybe it was there but it wasn’t noticeable as I have a fast connection to start with 🏻♂

Wow


I think I found the solution

All you need to do is

1. Make a backup on a computer

2. Factory reset

3. Set up the phone from that backup

4. It should work


This should work as I had the same isssue where my other devices were getting 50Mbps and my iPhone Xs max was only even sometimes getting between 12 to 0

And now I’m getting almost 40

Which is an improvement but it is still not perfect


I hope this works for eve

same issue. tried my 6s and my wife 6s. both have consistent speeds throughout the house. if I walk 3 feet away from my router, speeds cut in half. LTE also *****.


if I don't hear anything from Apple in 1 week, returning this phone. switched from android last year. came to apple to get away from the problems with Android OEMs. I did not pay good money for this to be happening.

Apple does not know what to do. Working with apple senior support and engineering and 5 times they have asked for logs and information. Now was told to go 24hrs off wifi completely. Regardless that is not the full issue. I am not their tester as I paid in full for this product. So far undecided if I am going to return the phone and walk away as support cannot even keep their story straight.

Brand new XS. I don't have this issue on my 6S that I still have.


Here's the issue. Wifi loading facebook or instagram videos (these are good sites to test on wifi) After a while, after a reboot, things are fast fast loading. After a few min and the rest of the day, if in WIFI in the XS facebook videos and instangram pages with lots of images and videos, LOAD SLOW, If I turn wifi off and use the network, it's INSTANT LOADING!


ANd ideas? Again, the iphone 6s is super fast on wifi, but the XS is not. Now, running a speed test in the xs shows same great speeds as the 6s does. BUt something is up with these phones as the wifi loading pages with images gets slower on wifi. Hope someone else can chime in....
