I’ve had this iPhone Xs for a while now have noticed the wifi is slow. I checked this versus my iPhone 6s, 7, ans a 8 and it's constantly half the speed using various apps like WiFi Sweet Spots, any router, etc. 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 iPhone 6s. 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. 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. People assume it's the wifi, but really it could be anywhere in the chain from app request for information to on screen rendering, burnswtning is up. I use this phone for work and can’t use it and have to use my older iPhone so I get faster speeds. Not happy.
