I continue to get the unable to download error message for iOS 15.3 update (8 Plus). I have 8GB of available storage. I’ve done the usual suggestions to no avail...

iPhone 8 Plus, iOS 15

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

  • You need at least 6 GB of free storage
  • 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
  • The phone cannot be in Airplane mode
  • You cannot still have a beta version installed on the phone


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