Well, if its pulling ~1mA, then it should only last about a month or two. (right?)

You could also pull battery voltages to see the battery "level" as well.

Hi, based on the results of my last measurement the sensor needs 90µA, while sleeping + consumption for transmitting, but this depends on the configuration.
The theoretical battery life just for sleeping (without battery self discharge) should be:
2500mAh/90µA=27777h
27777h/24h=1157d
1157d/365d/3,17a

I'm basically asking because everyone states that the step-up pulls like 1ma even arduino is in sleep. Your saying yours is not doing that?

@klim Hows the battery life looking?
