To update over the air from the phone all of these requirements must be met:

  • You need at least 10 GB of free storage for iOS 16 or 6 GB for iOS 15 or lower; more is better<—Most Likely Cause
  • You must be connected to a Wi-Fi network (and not a personal hotspot)
  • The phone must be charged to at least 50%, and preferably plugged in so it stays above 50% during the update
  • The phone must not be in Low Power Mode
  • The phone must not be connected through VPN, and it may be necessary to delete any VPN apps and VPN profiles
  • The phone cannot be in Airplane mode
  • You cannot still have a beta version installed on the phone
  • You cannot have a previous version that was downloaded, but not installed - go to Settings/General/iPhone Storage to look; if you find an iOS installer, delete it


If you can't meet all of them you can still update using your computer.
