Thanks for posting the screenshot. There are several things wrong with the method that you are using to update your iPhone.


  • Make sure that your iPhone is charged to at least 50%. I recommended that it be fully charged and connected to power.
  • Make sure that you are connected to a Wi-Fi Network
  • Make sure that you have at least 6GB - 8GB of free and available storage on your iPhone.
  • Then try and update it again


Read below for more requirements to update your iPhone. Make sure that your iPhone is setup to meet the following requirements before you attempt to update the iOS version over a Wi-Fi Network. Open Settings ➡️ General ➡️ Software Update: If there is an update available for your iPhone then it will be listed here. Follow the on-screen instructions to download and update your iPhone. 

  • 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
  • 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).
