Welcome to Android Central.

It should not take very long. I just updated the other day and it took all of several minutes. Mind you I did a half dozen different updates.

How long an upgrade takes depends largely on the model & capability of the phone, as well as how big the update is as well as how many apps you have installed.

If the update continues for much longer without showing any progress, you might try force-restarting the device (usually done by holding power & volume down).
