If iTunes Doesn’t Work, Try The Settings App (and Vice-Versa) Now that the iOS update is deleted, go to Settings -> General -> Software Update to download the update again. If you see the update file, tap on it, then tap Delete Update. Scroll down the list of apps below the Storage Recommendations and look for an iOS update. Occasionally, an issue with the downloaded iOS update file will prevent you from installing it on your iPhone.

While in Settings -> General -> iPhone Storage, check to see if the update has already downloaded. If you have more than 1 GB (gigabyte) available, then you have enough storage space to update your iPhone.

Make sure the switch next to Wi-Fi is on, and that a checkmark appears next to the name of your Wi-Fi network. We recommend using Wi-Fi instead of cellular data when downloading updates, as it’s faster and won’t eat into your data plan. Some updates, because they are so large, require a Wi-Fi connection. Your iPhone needs an internet connection to download new iOS updates. Make Sure Your iPhone Has An Internet Connection
