As a designer of embedded battery powered devices, I often find myself in need of tools that would enable me to build better products more efficiently. Unfortunately the tools I need are often too expensive – so I ended up creating Bluebird Labs to develop tools that are within the reach of the everyday engineer/designer/tinkerer. Bluebird Labs is entirely open source and I encourage you to take what I’ve built and improve upon it. I hope that you will find my products to be helpful and useful in your designs!

Hi Doug, I guess average will do if you are on the linear part of the discharge curve.
Making a couple of measurements at different points on the curve will probably work fine. Should be possible to figure out if there is a Ldo or DC/DC in the design.
Helge
Hi, really nice project. What happen if you add a buck-boost converter between your battery and your design? Current will not be constant from 4.2 down to like 3.2 volt. Same applies if there is no ldo to keep the load current constant. This could influence battery lifetime a lot.
Yes you are correct Helge. I am currently working on a solution to address the issue. I've thought in the meantime just averaging the two (4.2V and 3.2 V), not sure how close that will get to an estimate of battery life. I'll will post once I have new software to address that issue.
