Why is Quick Start taking hours and my data hasn't transferred?

Good afternoon DrIronpaw,

Welcome to the Apple Support Communities!

It sounds like you are trying to set up an iPhone with Quick Start. Can you provide a little more information about this issue? Which iPhone models are you trying to set up and sync from? Do both iPhones have the most recent iOS version? Does the new iPhone have the same or more storage capacity than the model you are attempting to transfer from? Do you have iCloud enabled for data like contacts, calendars, notes, etc?

You may need to restart your iPhone and set it up using a backup from your previous iPhone and enabling the same iCloud features on the new device. Take a look at the resources below:

Set up your iPhone, iPad, or iPod touch

Turn iCloud features on or off - iCloud User Guide

If you can't set up your new iPhone, please reply to this thread and we'll do our best to help you!

Take care.
