Here are my results, I checked the battery every 250 pages (the book has 1750 pages). About an hour after the first test (T1) I did it again but without charging the battery. (T2)

Page  T1   T2
---- ---- ----
   1 100%  69%
 250  89%  67%
 500  87%  67%
 750  87%  65%
1000  83%  65%
1250  80%  65%
1500  77%  63%
1750  72%  61%

We might need to rethink the test a bit, it doesn't look like there is much point trying to gauge the battery life based on how long it takes to drop from 100% to 90%.
