How to troubleshoot iPhone XS that’s unable to check for updates

Before troubleshooting, check your Internet connection. Fast and stable Internet connection is among the key requisites for installing iOS updates via over-the-air (wirelessly). Another thing to check is the Apple server status. To check, you can visit the Apple Support website then navigate to Apple’s system status page. If you see a yellow (warning) icon next to an item, then it means that there is a problem with Apple’s server and services are currently unavailable. Unfortunately, there’s nothing much you can do but to wait Apple engineers fixed the problem on their end. If the service icon appears in green, then the problem is likely on your end and thus, you need to troubleshoot your iPhone.

First solution: Turn Wi-Fi off and then on again

To update your iPhone wirelessly, fast and stable Wi-Fi access is required. If your device is experiencing Wi-Fi connectivity issues from slow browsing to intermittent or no Internet connection at all, then you need to deal with network problems first. Should this be a random network-related error, then restarting your iPhone’s Wi-Fi internet connection will likely fix the problem. As first workaround, try turning Wi-Fi off and then back on.

  • To do this, go to Settings-> Wi-Fi menu and then toggle the Wi-Fi switch to turn Wi-Fi off. After a few seconds, tap the switch again to turn Wi-Fi back on.

Another way to restart and refresh Wi-Fi internet connection on your iPhone is to toggle the Airplane Mode switch on and off.

  • To do so, head over to Settings-> Airplane Mode menu and then tap the switch to turn Airplane Mode on for a few seconds. This will disable or turn off wireless radios including Wi-Fi connection on the phone. After a few seconds, toggle the switch to turn Airplane Mode off again to re-enable wireless radios on the phone.

Wait for your iPhone to reconnect to your Wi-Fi network and then retry checking for new OTA update.

Performing the Airplane mode trick is like giving a quick reboot on the phone’s wireless network functions. It’s also a simple alternative method to clear out random issues and errors affecting the phone’s wireless functions.

Second solution: Reboot your iPhone XS (soft reset/force restart)

If the previous workarounds failed to offer some remedies and the error persists, then try rebooting your iPhone XS. A device restart or soft reset effectively resolves minor software errors and glitches including those affecting the phone’s Wi-Fi functions. For starters, here’s a soft reset is done on an iPhone XS:

  1. Press and hold the Side/Power button and either Volume buttons simultaneously for a few seconds.
  2. Release the buttons when the Slide to Power Off command appears and then drag the power off slider to the right.
  3. After 30 seconds, press and hold the Power/Side button again until the phone reboots.

You can also try a force restart if a soft reset doesn’t help. To do this, simply refer to these steps:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Then, press and hold the Power button on the side of the phone and then release when the phone reboots.

Performing a soft reset and force restart also helps clear cached files and temporary data from the internal memory. Insufficient memory space is also among the possible hindrances for iOS update downloading and installation. While this isn’t likely the case on your end since what you’ve got is a new device with huge storage capacity, it won’t hurt to check the current memory status just to clear memory issues out from the underlying causes.

Third solution: Delete/forget Wi-Fi network then reconnect

Another way to deal with Wi-Fi connection errors is to forget or disconnect from the Wi-Fi network and then set it up again to reconnect. This often needed when the wireless network in use gets corrupted and no longer working. If you wish to give it a try, then here’s how to forget Wi-Fi network on an iPhone XS:

  5. Tap tap Forget to confirm action.
  6. After forgetting the Wi-Fi network, restart your iPhone to refresh its memory and iOS and then go back to Settings-> Wi-Fi menu to set up your Wi-Fi network then reconnect.

If you’ve set up other Wi-Fi network on your device, then you can try switching to your other network and then try if you can update through that network.

Fourth solution: Reset network settings on your iPhone XS

Performing a network settings reset usually helps when dealing with network problems attributed to invalid network settings and server errors.

Before you do so, take note of your Wi-Fi passwords as you need to re-enter them later when setting up your Wi-Fi network. Then follow these steps whenever you’re all set:
