But it might be that still, even with some approximate "mean number of locations per page" –– using number of page turns for a battery life characteristics makes more sense than much more individual "time of reading".
Ok...so I just did a little test. I read for 37 minutes at font size 8, bold 4, light 12. In that time, I read 480 locations, so about 120 page turns. The battery dropped by 3%.

So...a rough estimation of 1% drop every 10 minutes for my reading style (variable font size, constant light at 12 and constant wifi on), so ~ 6% per hour.
