updating problem

My iPhone XR was updating overnight and it is stuck. I see the apple logo and when i press the volume up/down button it says it will restart when update is finished. I have a good wireless connection and there shouldn’t be a reason why it hasn’t finished by now.

Requirements to start and install an Update on an iPhone-

• 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.
