Maybe the battery is not yet well charged and then many smartphones have problems booting up.
I'll check battery status and cable next.

Well, the batters is a white and unlabeled brick with 4 gold contacts and 52g weight.
First, I though it is only a mechanical dummy, because I could not measure any voltage across any pair of gold contacts.
But in Ohm mode I got ca. 50 kOhm and 2.7kOhm between 3 of the 4 pins.
The fourth pin seems to be unconnected.
Unfortunately I could not match it with the schematics (Page 6 "Power") where the battery connector J600 should have 6 pins?

So at the moment I conclude that the battery is deeply discharged and the protector circuit has disconnected it.

How can I revitalize it?
Does the PinePhone do trickle charging if powered off?
