iPhone Xs wifi slow (half the speed of iPhone8)

Still get over 400 Mbps down and haven't shut off WiFi since 12.0.1 was released.

How do you factory reset the phone ? Because I’m having that same issue.

updated to 12.1

Wifi reception is 2/3 bars. Still no improvment.

Don't judge by "bars" - they are just a thumbnail representation of signal strength.

Judge by actual speed.

Nope tried and still slow

This doesn’t look right, does it?

What speed are you subscribed to?

I know CenturyLink does offer a tier at 10M down, 800K up, and this would be a good speed test for that tier.

If you don’t mind me asking, who is your provider? Your speed is in a

whole different ball park....different city even.

I saw issues like that back in iOS 12.0, but not since iOS 12.0.1 was released, and certainly not in 12.1 or 12.1.1.

It didn't fix the problem for me. I had to swap the phone and still.

So, this is still a problem! People think it’s hardware.

Nothing works. The only thing that seems to work is to separate the two frequencies, 2.4 GHz and 5GHz and force the iPhone to connect to the 5GHZ band. So far the connection has been steady over 120 mbps all day long.

I have had the two frequencies set separate for long time as I had issues with not sticking to 5 ghz without having separate. As long as I am in house it seems no matter the strength of the signal on the 2.4 and 5 I get the same consistent speeds I have gotten with all my iPhones and iPads and MacBooks based on my ISP plan.

where I start to have issues now with the Xs vs X and older phones is that when I am outside my cell signal is still not very strong in neighborhood but my WIFI always reached me fine in yard around house. -- 2-3 out of 4 WIFI bars but it worked fine up til X. Now my Xs has a flakness with WIFI outside (developed after a couple days was fine for awhile) that results in loosing internet in various apps and my cell is not strong enough to be used WIFI is needed in my yard. I can see the bars flicker from 3 to 1 to zero back to 2 and 3and when I do speed tests outside the WIFI even when showing 3 bars like inside fails to find/connect to server to do test most of time and when I does the speeds are dismal so my phone is having problems in connecting through house outside but no problem even in distant rooms as long as inside.

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?

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.
