Here are the conditions that must be met to update iOS:

  • You must have a fast Wi-Fi connection; you cannot update over cellular data
  • The phone can not be in Low Power mode
  • The battery state of charge must be above 50%
  • You must have at least 3 GB of free storage
  • You 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).
