I can't charge the Pinephone while it's powered on.
Finding a power supply with the specified values (15W (5V 3A) USB -PD) and USB-C is not that easy.
So how about the power supply of the Raspberry Pi 4? It comes with USB-C and 5.1V/3A.
Does that 0.1V really make a difference?
If you don't recommend it, could you point me to a different one?
I'm in Europe btw...
Thanks for your help!
I had the same problem as you, it was fixed by blacklisting the anx7688 module
echo "blacklist anx7688" >> /etc/modprobe.d/blacklist.conf
I'm afraid I'm not expert enough to understand that. What exactly does that blacklisting do and how does that solve the problem?

The BC ones will 'Just Work' while the PD ones need the right combination of ANX firmware and kernel driver support. Details here: https://xnux.eu/devices/feature/anx7688.html
So I understand anx7688 is a driver handling the charging process. The description says:
Quote:In some configurations (with 3A USB-C PD charger) AXP803 resets the VBUS input current limit by itself to 500mA, so PP will not charge (much)
- Forcing the input current limit back up leads to instability (looks like AXP is resetting the limit due to voltage drop on VBUS) and input current fluctuates between 0 and ~1.3A
Is there a way to check if that happened? And if so, it can't be fixed since fixing leads to instability? That means a problem, right?
Or am I wrong with this assumption?
