Slow internet is among the most irksome problems you can experience on a smartphone. There are many potential reasons why this might happen on your iPhone XR. Likewise, there are many potential solutions. Before troubleshooting your phone, try resetting the Wi-Fi router/modem. If the problem persists, continue with one of the methods laid out below.

Reboot Your iPhone
As with many other issues, a phone reboot/soft reset might help with slow or unresponsive internet. Follow these steps to perform a soft reset on your iPhone XR:
Press and hold the Power button (also known as the Side button) and one of the volume buttons simultaneously. Hold them until the “Slide to Power Off” slider appears.
Once the slider appears, drag it from the left side of the screen to the right. This will turn the phone off.
Wait for approximately 30 seconds and then press the Power button. Hold it until you see the Apple logo.
Troubleshoot Wi-Fi Connection
If the issue is not with the router, it is most likely with your phone’s Wi-Fi. There are several things you can try.
Turn It Off and On
The first and most common thing to do is to turn Wi-Fi off and on again.
Unlock your iPhone XR.
Launch the “Settings” app from the Home screen.
Tap the “Wi-Fi” tab.
Tap the slider switch to toggle it off.
Reboot the phone.
Launch the “Settings” app again and go to the Wi-Fi menu.
Toggle the Wi-Fi on.
Forget the Network
You can also try forgetting the network:
Unlock the phone.
Tap the “Settings” app icon on your Home screen to launch it.
Find and tap the “Wi-Fi” tab.
Find your current Wi-Fi network and tap the “i” icon next to its name.
Next, choose the “Forget This Network” option.
The iPhone will ask you to confirm your choice. Tap the “Forget” button.
It is also recommended to forget all other saved Wi-Fi networks in order to prevent any possible conflict with your current network.
Reset the Network Settings
Finally, you may want to try resetting your network settings:
Unlock the phone.
Launch the “Settings” app from the Home screen.
Tap the “General” tab.
Tap the “Reset” button.
Pick the “Reset Network Settings” option.
Type in your passcode.
Your iPhone XR should reboot on its own after the reset. When it turns back on, go to Settings and turn the Wi-Fi back on.
Clear Browser Cache
Sometimes clearing your browser’s cache might help speed up your browsing and downloading. Here are the steps for Chrome and Safari:
Chrome
Unlock the phone.
Launch Chrome.
Tap the “More” icon in the upper-right corner.
Select the ”History” tab.
Pick the “Clear Browsing Data” option.
Choose the items you want to delete.
Tap “Clear Browsing Data” to confirm.
Safari
Unlock the phone.
Open the “Settings” app from the Home screen.
Tap the “Safari” tab.
Pick the “Advanced” tab.
Pick the “Website Data” option.
Tap “Remove All Website Data”.
Final Words
At this point, you might consider updating your iPhone XR. If that doesn’t bring the desired results, a recovery via iTunes or iCloud could potentially solve the problem. If all methods fail, take your iPhone XR to a repair shop or contact Apple support.
