Did you count page turns at all? Probably a drop in the ocean considering those blaring light levels, and not necessary unless you're reading very different genres/difficulty levels, but just wondering.

I can't read either with frontlight at 100% in a dark room. I had to perform the test with daylight, and during night sessions I really had to enlight the room. Even there it wasn't a pleasant experience (eyeburn).
I haven't count page turns at all. It didn't come to my mind. I must say that I don't really like the idea of measuring battery life as page turns: the amount of signs can vary a lot from one user to another (especially with the amount of tweaking the Kobo allows). Time, on the other side, is universal.

I checked once if 60 minutes of non-stop reading increased the counter to 1,0 hour. It was the case, so I guess that the statistic counter is working accurately.
But even if it's not perfect, the generated values are still informative and useful to measure the relative impact of light intensity on total battery life.
Another objective criterion is the number of books I was able to fully read between two charges. With 10
easy-reading litterature (400…500 printed pages) finished with no frontlight, I guess it comes close to 80 hours
About page refresh I don't know how much it impacts battery life. I put it to 128 pages because my H2O keeps a good quality display (even if Regal technology is not implemented in this device) to my eyes. There are some artifacts but overall quality is OK to me. I kept this setting for my test.
I also wonder if KePub reading increases the battery life over regular ePub. The formats are nearly the same, but the engine on the Kobo is different. ePub page turns is a bit slower (and supposed to have a bit more typographic accuracy). So I wonder if it requires a bit more CPU power to compute the page (hence the additional time), which should negatively impact the battery life on ~10.000 iterations.
