iPhone Xs wifi slow (half the speed of iPhone8)

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.

If the wifi is so bad that you can’t even watch full HD video and your day to day uses are too slow then refund the phone

But if you can handle just a slower connection then keep the phone and just keep checking if their is an update

That would be my op

Don't know if this will work for everyone else, but I had the same issue since purchasing the XS; Just performed the iOS 12.0.1 update and that seems to have at least fixed the wifi issue. Don't get me started on the "restoring from a backup" problems. I have no doubt that the crawling wifi speeds I've had since day one are the culprit.

I did the update and now my WiFi is even worse.

All my other devices on WiFi work fine (mac,dell, iPhone7) and I can’t do much of anything unless I disconnect it and try to run off LTE/3G.

Very frustrating as I just dropped sprint and moved to Verizon. I really don’t want to go through the hassle of returning the phone.

The WiFi seems to get slow overtime and eventually stops working. I turn off my WiFi and back on and it crawls. I hard reset my phone and it went back to normal. This is like the 3rd time I’ve had to do it in a week. Running iOS 12.0.1

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 🏻♂

Xfinity by Comcast, their Gigabit cable modem tier.

My WiFi router is an 802.11ac Apple Time Capsule, which admittedly maxes out at about 650 Mbps wired, so I just use it as a WiFi bridge and leave routing to a Ubiquiti EdgeRouter 4, which can route at Gigabit line speeds.

I tried the same thing.. it’s actually improves a bit but not much.. I have 600 Mbps speed.. my XS was giving only 40 to 80mbps max.. after factory reset now it gives around 120Mbps..but still every time I open certain apps it’s keep on loading .. for example when I open LinkedIn it’s take almost a minute or more to refresh.. really frustrating.. does not have any loading issue when connected to LTE.. 120 Mbps is still fast.. eventhough I dont get my full speed wifi on my XS..but it’s acts like 1.2Mbps.. sometimes feels like smashing the phone.. my 8 plus has no issue eventhough I had only 150Mbps speed that time..earlier I thought its the issue with the app developer .. but when same thing start happening on so many other apps.. only on wifi.. ? Only on XS?

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....

The iphone 6s doesn't do it that on wifi. I've tested this over and over. It's not the router..... It's the XS that works fast after a reboot, but after a few min loads sites with pics and vids super slow.... Doing a search online has this effecting others as well.

It's hard to notice on normal sites, But try facebook app and go into someones's photos or instagtram pages with videos,. the videos will play, but at reduced resolution, not super clear.. Then turn off wifi and videos get clearer. You may not notice this unless you use your phone A LOT.

I have the same Problem .Sometimes Instagram and Facebook is so slow, cannot open comments etc, but when i change to LTE everything is Fine . Do you find any solutions? Its so annoying. Thought about to replace my XS , i am not sure about that. Maybe its a Software issue.

Same issue as with most people here and online. I'm on the latest update, and wifi still gets slow randomly. It's like a few posts above, paraphrasing him, LinkedIn take almost a minute or more to refresh.. Same for Instagram, Facebook, and others...really frustrating.. does not have any loading issue when connected to LTE... I get about 50Mbps wifi but it acts like 1.2Mbps..." .

Even more frustrating is I also have the well known system-wide stutter issue after a period of inactivity (on animations or scrolling), so this data loading issue means even more stutter/jitter on an already not smooth phone.

I have tested the XS against three phones side by side at home: XS, iphone 6(!!) and Pixel XL, both other phones work great on wifi, on the same apps, so I know for a fact it's not the app (even cross platform!) nor the router. It's 100% the phone.

Speed tests are not the problem. I get super fast speed tests. It’s the loading of website that’s everyone is complaining about. People assume it’s juar weak WiFi. See the other threads on this. It’s a shame. I have an iPhone 6s right beside this ca that loads pages instantly where the XS doesn’t.

Then there is something else going on, because I don't see that, either.

Others have complained about performance in apps like the Facebook app, but have found that there are similar issues in the Android app and no such issues if you view Facebook via Safari.

Definitely something is wrong. I have Android (pixel XL OG) and have tested several data intensive app like Instagram side by side, no similar loading issue on the Android apps like you're suggesting. No issue either with my iPhone6. It's clear this is something on the XS.

I agreed with the previous poster that people assume it's the wifi, but really it could be anywhere in the chain from app request for information to on screen rendering.
