ios18 update on brand new iphone15 running for hours

Everyone I know that has updated so far, has said it's a very slow process.  Few hours slow, I am not sure.  Are you seeing any sort of progress in the update?

What is the wifi speed that you are trying to update it on? Were you able to resolve the problem?
