Would this make sense?
Alternatively, a slider-switch could be added to the back of the phone, made accessible from the outside (by drilling), which would slide under the Pogo pins that feed power from the battery, disconnecting them when desired.
No matter how it's done, it really looks like the battery inside the PPKB needs some sort of hardware switch. This way, it will truly behave as what it really is: a powerbank, not just an extra battery. A powerbank which you manually connect and disconnect, and charge separately on its own port.
This is quite a great idea!
Do you know which cables we would have to solder to this switch?
Would the keyboard as a keyboard still work?
There was this other guy, adding a "ideal diode":
