Which laptop from Apple gets the longest battery life possible?
Well that is going to really depend on what type of harddrive is in the macbook/macbook pro.
7200 rpm drives run faster than the standard laptops that are in the macbook and macbook pros. the higher the rpm the faster the drive the more power it consumes. now with all that being said. the macbook i think gives the better battery life. the power consumption on that laptop is 60 to 65W compared to the macbook pros 80W.
I'd either guess the MacBook (smaller screen = less battery drain) or 17" MacBook Pro (biggest battery).
Of course, that's not really helpful, since I just named 2/3rds of Apple's laptop lineup![]()
