Copy/paste removed the tabs.
Show off!And code tags probably would have kept the tabs.
That's some pretty major movement... 4.35v when 100%, then down to 4.20 (still 100%?), and then suddenly 3.97v (91%)... would have to be a pretty major current spike... more than I would expect to see on a SBC... maybe the charge IC throttled down a bit because it was warming up? Either way, both your and VoxUnius's results suggest 3A isn't keeping up when the PBP is loaded up.
Are current measurements not working atm? This is the sort of thing I get for the A64 Pinebook... negative when the battery is discharging, positive when the battery is charging... possibly negative if the external PSU couldn't keep up with the load. I was expecting to see something more interesting than zeros!

A tiny correction: even 4A is not enough. Either that, or some internal logic limits the current from the power adapter.
