How long does it take to Upgrade to IOS 11 from IOs 10

[iMore Question]

I am upgrading but it is taking a long time

Define a long time, in this regard.

Anyway, it depends on the device, the internet connection and download speed. Are you merely upgrading over the air or are you doing a clean install?

From my perspective, it shouldn’t take more than 30 minutes.
