Why does it take forever to estimate time when update

Do you have a strong Wi-Fi connection to the Internet?

Please look at the checklist below when attempting to update your iPhone. Make sure that the conditions listed below are met when you start to update-

• The phone must be charged to over 50%
• Low Power Mode must be OFF
• You cannot be connected through VPN
• You must have a Wi-Fi connection (not cellular)
• You should plug in the phone or put it to charge to assure it stays on and connected to Wi-Fi.
