I noticed that the mainboard in the Pinebook Pro that I received in August 2022 is different than the other earlier Pinebooks Pro that I have. But I didn't look for anything else different. I haven't read any accurate reports of things changed.
But I have noticed that battery life is greatly improved. Or charging or usage has improved, I don't know which. Even with the display brightness turned all the way up, the battery remains full no matter what I'm doing.
This isn't a software improvement, I don't think. I'm running NetBSD 9.3

Interesting! What's the screen on time, compared to last time?

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.
FWIW I have PBP from first batch and it does not drain battery (at least not below certain quite high level) even when left compiling for days as long as it's cooled with a cooling pad. I think battery IC has a temperature threshold when it stops charging battery so perhaps in newer PBP it's only improvement to cooling around IC or threshold temperature.
It could be cooling.
My second batch sounds like your first batch. This latest one is markedly better. The battery does not go below 100% when plugged in.
