No, it turns off the charge current. See page 86 of the PCF50633 user
"Battery fully charged: When the battery is fully charged and the
charger is in Battery Full mode, the charge path is disabled (the
USB-BAT FET is off)."
I've charted this by sampling the "capacity", "voltage_now", and
"current_now" /sys files, but I don't have time right now to dig out
that file and post it.
