Possible causes 

Aside from iOS bugs, there are also other factors that you should consider looking into when dealing with slow internet browsing issues on  your iPhone XS. Among them is your account status. If you’re on cellular data, your internet connection may be throttled, especially if you’ve already exceeded the data limit. As a result, your internet slows down. But this isn’t likely the case if you’re subscribed to a post-paid or wireless plan. Nonetheless, that would still depend on the terms and conditions imposed by your carrier.

Other factors to eliminate:

Software-related issues like a problematic browser in use, data corruption affecting the iPhone XS internet system, and iOS bugs are also other possible causes to eliminate. Random firmware crashes on the network device can also be the root cause of the problem. In worst cases, internet problems like slow browsing can be attributed to hardware damage on either the network device or your iPhone. 

That being said, both software and hardware components must be scrutinized when dealing with relevant issues. Before rushing to a service center, I’ve mapped a few simple yet very effective solutions for you to try on. Keep scrolling for more detailed slow internet browsing solutions for your iPhone XS.

Recommended potential solutions

To test your iPhone XS internet speed, you can use free online resources such as fast.com and speedtest.net application. If the speed test results in average or more than half of the actual data speed provisioned on your account, it’s an indication that you’re getting the right internet speed. It’s usually a bit lower than the actual speed you are subscribed to but it should be closer.

Before troubleshooting, make sure that your iPhone is close to where modem or router is. The farther your phone is from the network device, the weaker the signal it gets. As a result, the internet connection is either very slow or intermittent. To rule out proximity issues, stay close to the wireless router or modem while performing the following procedures.

First solution: Power cycle or reboot the modem/router.

The very first, if not the last potential solution most internet support people usually give you is the so-called power cycle on the modem or router. It works similar to a soft reset on the phone when it comes to resolving minor issues including post-update internet symptoms. This however can only be done if you can access the modem or router at the moment. Just follow these steps:

  1. Find the power button/switch on the network device then press and hold on it until the device powers off.
  2. While powered off, unplug its AC adapter from the power source and keep it that way for about 30 seconds up to 1 minute.
  3. After the elapsed time, plug it back into the power source then turn it on again.

The network device will then initialize its start-up sequence. Just wait until all the light indicators become stable. Also make sure that the Wi-Fi indicator appears green. Any red light indicators on the modem or router usually denotes a problem that requires immediate solution. Otherwise, internet connectivity issues will occur on all connected devices.

 

Second solution: Reboot or soft reset.

Minor internet problems can also be remedied by a soft reset or reboot on your iPhone. This is one of the main reasons why it is highly recommended to reboot your device after installing new updates. Thus, follow these steps to soft reset or reboot your iPhone XS if you haven’t already:

Doing so can help rectify minor wifi issues on your iPhone including those triggered by the recent system update. There are many different ways for you to do this.

Reconnect to your Wi-Fi network then launch your browser to test your internet speed.

 

Fourth solution: Delete and re-add Wi-Fi network on your iPhone XS.

Some updates would ruined your network settings and thereby caused your iPhon XS Wi-Fi network to become corrupted. As a result, various types of internet problems including slow internet or intermittent connection would instigate.

  4. Then tap the option to Forget this Network.
  5. If prompted, tap Forget Network to confirm network deletion. The network will then be removed from the list. 
  6. Repeat the same steps to forget other unused networks to prevent any of them from causing conflicts with the network in use.
  7. After forgetting the Wi-Fi network, turn OFF the Wi-Fi switch then restart your iPhone to clear its network cache. 
  8. As soon as it reboots, go back to Settings-> Wi-Fi menu then re-enable the Wi-Fi switch to view the list of available Wi-Fi networks. 
  9. Select your preferred Wi-Fi network then tap Join or Connect.
  10. If prompted, enter the correct network password to proceed.

Wait for your device to successfully connect to the Wi-Fi network and then check your browsing speed again to see if it’s already within the accepted range.
