How long it takes will depend on many factors including download speed. It is usually best to update overnight when plugged in or when you are not planning on using the device for at least 45 minutes. You will not want to attempt to interrupt the process if you change your mind. Just let it do its thing.

It should take about 45 minutes or less to complete the update if you are on a fast internet connection. The timing will vary.
