I have both an 8.9 inch and a 10.1 inch, a 3 cell, and a 6 cell battery. Is it just me, or does the 10.2 last longer when compared to the 8.9 inch when using the same size battery (of course starting with a full charge). Like using the 3 cell, I get about 2.5 hours on the 8.9, but on the 10.1 I seem to get about 3.25 hours...
