|Supply and BSI resistor|
With a bit of cutting, it will now be possible to fit the original back cover on again! The 2k4 resistance did indeed turn out to be the devices BSI signal, the pin being shared with the NFC antenna. With the resistor in place and the supply voltage set to 4.35V (the full charge terminal voltage of a 3.8V Li-ion cell) the device is now perfectly convinced that it has a fully charged battery attached.
