T14 G2

Just picked up a gen 2 for $700 usd. It's a touch screen, not that it matters with 32gb of ram and a 1TB ssd, amd processor. It was suppose to be a gen 3 but I didnt read the description close enough. This will be primarily a school laptop with office and zoom being the most taxing. Debating returning it.

My question is what should I expect for batter life to be vs gen 3 and are there any common issues? I know my t480 had a usb bug that needed to be patched.

With the current state of the US market are there any better recommendations?
