Battery life regression is something that is very tricky to test. It is very dependent on the hardware you use and how you use it. Since all batteries degrade over time, it's also difficult to tell if there was a regression, or the battery needs to be replaced. I'm not saying it's impossible or anything, but it would be tricky to interpret the data correctly and it would be very difficult to get tests like these automated properly. We can't really even talk about battery life tests until we address the issue Naoki brought up in https://bugzilla.mozilla.org/show_bug.cgi?id=814193#c1

This is the kind of thing that I imagine each OEM would have testing for (and probably in a much better environment/setup than we could hope to manage). The easiest thing we could do would be to communicate with them and make sure they let us know if they notice any worrying regressions.

I was wondering if we have (or already have) plans for testing battery

Battery life is a large concern for mobile/smartphone users and it will
be interesting to have some areweusingtoomuchbattery.com site (or
something similar) to track battery life of different Firefox OS
versions going forward.

Thoughts? Has any bug been filed, if needed?
