The usb stick will be unmounted by a shut-down, but the usb port it's pluged into will still be live. Whether that's a bad thing or not I simply don't know.

I bought an expensive microwave. So I wanted to know the main reason it breaks down.
Turns out the microwave dies because the family slams the door shut. (The door gets rickety and the electric connection is lost).
But the main reason a microwave dies is because its left on all the time. The circuit board fries.
With a USB flash drive unmount it early.
The SSD of the USB flashdrive will last forever. But not the circuit board it exists on.
Over time, the circuit board of the USB flashdrive will fry.

I am sure there will be lots of members that question your opinion or theory. Technically its a component on the circuit board that will fail and not the board itself. Flash memory has a limited number of writes and can one can easily write a loop to wear it out long before that board fails. Some of the most common causes of board failure are age, heat or electrical stress.

Rep:
shutting down a computer you still end up with live ports?

If the computer has been shut down, how can the usb port be still live?
USB flash drives are just another type of electronic circuit, with a controller, etc. Just get a quality one, and back up your data, nothing lasts forever.
No,you don't have to unmount it. Normally random programs don't access it, so it could be left in all the time.
I've know system admins to run a virtual machine off a USB stick on a bare metal hypervisor that runs and entire classroom of computers dual booting Windows and MacOS. He wasn't worried about frying.
I unmount USB drives because I use them elsewhere, may forget to unmount them when I remove them.
I also run updatedb every hour, don't want USB drives to be included - but I could remedy that in /etc/updatedb.conf.
The guy who wrote the last hardware columns for Dr Dobbs reported on a project that used a USB drive, updated the same variable every 6 seconds, burnt out that cell in relatively short time. This was before the load-leveling managers that equalized cell usage by separating the logical addresses from physical addresses.

Some PCs & laptops keep power to certain ports for charging devices, etc. It totally depends on the manufacturer if the port remains live for power or not. AFAIK none are active electronically though.
