I also interchanged the batteries between both pinephone versions and charged as above. No more batteries issues.
Quite frankly, this is rather confusing. None of the actions you've described would lead to achieving a battery charge level higher than the default. Please, read my post above for a detailed background explanation.

What I referred to in my post above was the battery calibration procedure mentioned in the AXP803 datasheet. Of course, the procedure must involve charging the battery fully and letting it discharge completely, but the datasheet also briefly describes the use of a few AXP803 registers; see pages 43, 44, 79 and 83–85 of the datasheet for more details.
