Hi all just curious , would the battery life on the r2 with the sandy bridge i5 option be the same battery life as the r1 ?
I've heard from r2 owners that they get around 1-2 hours better battery life than r1 . (r2 = ~5-6h , r1 = 3-4h) So what would the battery life be like for a r2 with an i5 ? I plan to buy a m14x soon .
Thanks !

There is also a user who has post his/her finding, though the CPU is i7 IVB, but it should give you the idea: Personal battery findings - very good! -
Thanks for your response . It helps a lot .
But why would it have better battery life if optimus is on ? Correct me if I'm wrong , but I thought optimus completely turns off the gpu , thus making the gpu not consume any power . So then wouldn't the i5 on the r1 and r2 be the same ? -

Optimus is always on , so you can swap gpu , usually it will detect automatically , if you open any programs that require high 3D , it will use Nvidia GPU , normally it will run with IGP HD4000 to save battery life. Since you have m11x , you may try open Nvidia CP -> Manage 3D Setting -> Preferred GPU - Auto Select/IGPU/High Performance Nvidia GPU.
As CGSDR mentioned :

Yea I'm aware of how optimus works .
So would a r1 with an i5 have the same battery life as a r2 with an i5 ? (obvs not when playing 3D games , but just normal work/web surfing) -

Probably the same , since r1 , r2 i5 use HD3000.
m14x r2 + sandy bridge i5
