Thank you! I notice that you say sleep mode uses 55-65mA and Daniel says it uses 100mA. I wonder if different firmware accounts for that?

Additional thought. The camera has to work with variable battery voltage, so it needs constant voltage power supply to run the circuitry. As the battery voltage drops, this will require more current to keep the same power going into the camera, while the converse is true.

I rechecked my EM5. With the battery down at 6.7 volts, which is very near the point where the camera reports "dead battery", I got a sleep current around 125 ma.
