I saw this too (but not for that long). Going into a shell I saw that

what is happening over this time.
I may be wrong, but I noticed in a previous upgrade that in that
phase the machine is disk-limited as it is executing a great
quantity of sync() functions, related to the rpm database.
I would really like a simple way to turn the sync() stuff off
when doing an upgrade.
I know I know, it is dangerous and "libeatmydata" etc., but
an upgrade is already considered a risk by me, so I always backup
before upgrading; at that point, I would kick the sync() stuff
out of the way very happily.
You might want to run iostat and save the output during upgrade. Even on a
laptop the upgrades don't seem to take all that long. Before I offer any tricks
to make that faster, see if you can find out why it's slow.
You might look with hdparm and see if your disk has cache disabled, look in
/var/log/messages for any reported retries, etc.
