Here are some measurements of an Emisar D4v2 Tintramping, done with a 100 Ohm shunt resistor.

Aux LEDs off:

FWIW, the wide regions of increased current are fixed now. I didn’t have it properly going into the ADC sleep mode during measurements, so it stayed on way longer than it should while checking the battery.

Overall, the fix seems to reduce average standby current by about 15 or 20 uA. With aux LEDs on low, that means a drop from about 100 uA to 80 or 85 uA.

Here’s a measurement of the updated version. Same setup.
