I can't believe the converter or charger are sucking up 4.4mA. This is kind of disappointing to say the least. The whole thought process was that with everything asleep, the battery drain would be negligible.
According to the datasheet for the converter, the quiescent current is less than 50uA and for the charger it should be less than 5uA. What could I be missing here?
You could quickly find out by using a razor knife.Cut a power trace, insert the ammeter across the cut, then solder the trace.
