I can't swap (different physical locations), but I can say with certainty that the old one isn't very worn down; because the battery life is very comparable to what it was when it was new.
As for screen on time, the new one is on all the time, and compiling (processors at or near full speed all or most of the time). This is something the other two Pinebooks Pro that I have could never do; not without the battery draining, with the charger plugged in. This one will actually charge (albeit very slowly) under these conditions. And I can say it's not the charger because I've been using the charger that came with my first PBP (second production run) with the new one.
I'm very interested to see if anyone else has observed this.
