Very low battery (but charging) causes boot failures
#2
I have a similar problem, which might be the same problem, or it might be a different one.
I have found that if I run the battery totally dead and then plug it into a charger then it draws 1.72 amps from the charger.
If I then boot it up the charge light stays on, and the charge indicator in the system tray says that it's charging, but actually the current draw on the charger drops to zero amps.
I have tried this with both Manjaro and Armbian.
I am charging through a Syncwire dual port 3A charger, which no longer appears on their site, and this cable https://pine64.com/product/2-meters-leng...wer-cable/

I have just measured the voltage coming from the syncwire charger.
It delivers 5.19 volts when the PBP is taking 1.72A from it (not booted up).
With no load on it it's delivering 5.33 volts.

Is it possible that the PBP is more fussy about what voltage the power supply is when it's booted up then when it isn't?  Is 5.33 too high?
