OK so if I understand correctly, the phone battery discharges as the connection between it and the keyboard battery is limited to 500 mA. So even though there is enough juice in the keyboard battery and the keyboard battery is connected to a mains charger the phone battery discharges.
This can easily be tested by running the battery down to a certain level, then sleeping the phone. If there is still sufficient charge in the keyboard battery then while the phone is suspended then the phone battery will be charged by the keyboard battery.
OK I let the PinePhone suspend itself at around 87%. An hour or so later I woke it up an the charge was 92%. The keyboard was not connected to a charger so the only thing that could have charged the phone battery is the keyboard battery. So I guess time to experiment with changing the charging current value.
