Make sure that your iPhone is setup to meet the following requirements before you attempt to update the iOS version-

  • Your iPhone must have a fast Wi-Fi connection; you cannot update over cellular data or a cellular hotspot
  • The iPhone can not be in Low Power mode
  • The battery state of charge must be above 50%
  • Your iPhone must have at least 6GB or more free storage space
  • Your iPhone cannot be connected through VPN
  • If you are not planning for it to update automatically you should turn this option off, as it will only update when the phone is plugged in, connected to Wi-Fi and locked
  • You should leave the phone plugged in until it finishes updating, both to assure that it remains above 50% and to keep Wi-Fi enabled (Wi-Fi turns off when the phone sleeps if not connected to power).
