iPhone X, iPhone XS, iPhone XS Max And iPhone XR: Internet Speed Slow (Solved)

So, it’s the slow internet speed once again… The iPhone X, iPhone XS, iPhone XS Max and iPhone XR, despite their perfect configuration, can still manifest such issues. But what you see will very much depend on what triggered the problem in the first place. And the faster you identify the potential cause, the faster you can fix the slow internet speed.

Below, you will find a list of possible causes and suggested solutions. Try to constantly compare it to what you’re going through. For instance, if you’re only having problems with loading the Facebook newsfeed, you can suspect a website or app related issue. But if you’re encountering similar problems on more than one website, you can extend your area of suspicions. Let’s get straight to those examples and you’ll see what we mean.


When the internet is slow on the iPhone X, iPhone XS, iPhone XS Max and iPhone XR …

  1. You must check what kind of signal you have on the Wi-Fi network;
  2. If it’s not a signal strength issue, you can check other similar websites, for a comparison; or even return later on, when there probably won’t be so much traffic on that website and your connectivity could work better;
  3. If the website doesn’t seem congested, do not ignore the possibility of the network being congested – checking the hours when the data traffic should be the lowest might give you some clues;
  4. All of the above left aside, focus on the apps – is there anything running in the background that should not be there, taking up from your internet bandwidth?
  5. How about the physical memory of your device, are running low on your internal memory?
  6. How about the cache of the Internet app, would it need any kind of intervention? Maybe it got corrupted and you must clear it.
  7. Last but not least, how about the software? An internet browser or even an iOS update could change anything?


If it’s nothing from the entire above and you know for a fact that you haven’t exceeded the mobile data plan… The time has come to take out the big guns!


First, disable Wi-Fi Assist on iPhone XS, iPhone XS Max, iPhone XR and iPhone X:

  1. Go to Settings;
  2. Open the Cellular list of options;
  3. Turn off the Wi-Fi Assist listed in there.


Second, clear the cache partition:

The wipe cache partition on iPhone X models is a process that will erase the cache of the operating system. Whatever general cache problem you had, it should be gone soon after that. Hopefully, this will make your iPhone’s internet speed get back to normal.

You must not fear any of the steps involved in this wipe cache partition process because your data is safe. If you insist, you can create a backup first, just to be sure, and only then initiate the wiping process. Whatever works for you, but just start with it and see if this action has any effect on your initial problem.


Third, consult a specialized technician:

It’s becoming more and more obvious that you are running out of options, isn’t it? When the websites don’t seem to have any problems, other people with other devices, connected to the same network don’t seem to have any slow internet speed problems… It all narrows down to your device. And you’ve disabled the Wi-Fi Assist that could have randomly interrupt your Wi-Fi connection, not to mention that you’ve wiped the cache partition!

What else will it take to convince you that the solution to your iPhone XS, iPhone XS Max iPhone XR or iPhone X slow internet problem lies in the hands of an Apple technician? Give this option a try because, when most things don’t work, there’s a high chance that you have a hardware problem. If changing the wireless module from the iPhone is all it takes to get through with it, why not do it sooner rather than later?
