How much time does it take to complete installation of Windows 10 for phones?

[Windows Central Question]

I put my phone up to install this update at 5am and now is 10am and it's still spining. Is something wrong?
Please, someone, i need an answer for my question.
Thanks a lot.

Soft reset.
After the phone restarts it will resume the updating process.
Plug it in and leave it for an hour.. Shouldn't take any longer
