New iphone 13. Has been trying to restore from icloud for over 12 hours now and shows time remaining 11 hours.

No, it is not normal UNLESS you have a very spotty WiFi connection. Has your iPhone been connected to power and Wi-Fi all this time? If NOT then ensure that it is connected to your charger with a solid Wi-Fi connection.

If you can back out of it then do so and start over again.
