    I see this topic is actually hit on today regarding the Haswell chips, but is there any evidence out there to show how much more battery consumption there is with the higher-clocked IB chips compared to the lower ones? I've been eyeballing a refurbished 2.7Ghz model (16/512), but battery life is important, and if it's going to eat noticeably more battery than a 2.3 or 2.4, I may have to avoid it. The upgraded CPU speed isn't really on my radar, it just happens to be the option that Apple has with 16/512 for a great price.

    Considering the L2 cache is the same, and turbo is higher with higher clock speeds. The battery should be lower, but depending on how you use it. If you use it normal to idle, then it could be no more than 15 minutes of battery.

    I see there's also a refurb 2.6 option, which will reduce the battery drain some, but it's a June '12 model...is there any good reason NOT to try that one over a Feb '13 model? Aren't they essentially the same?
