True. That's why I'm looking for the number of hours improvement. If people that used to get say 6 on their SP1 can get 10 on the SP2 using it the same way, then people like me will be able to figure out about how much more they will get if they upgrade. MS said the SP2 would get 75% longer batter life. I'm one of those people that only gets about 3.5 hours on their SP1. +75% would only give me about 6.1 hours. I don't know if I'll drop a grand (I'd get the 8/256 and figure about $500 for my 128 used) for about 2.6 hours more life. I'm tempted. I just feel like 7 is my min.
...who am I kidding, I'll probably get one anyway .
Haswell is estimated to save 20% battery
= 3.5h * 1.2 = 4.2h
Then Power Cover will have a 30Wh battery which is 71% of the Pro's 42Wh
= 4.2h * 1.71
= 205% = 7h 12m
