I definitely feel that the i5 is more economical with the battery, i did a calibration and I am getting about 7-8 hours out of the battery with resonable use...
Brightness 50% ish, transmission going, browser going - macrumors/light stuff
itunes going that kinda stuff, pretty impressed
i5 is where its at my man.
Here is the final word, as Anand finally tested the i5 vs i7 for battery life...i5 is the one if battery life is your big concern
I currently use a 13" 2.53 with SSD and the experience is perfect in terms of responsiveness, little heat generated, battery life, display ...
But as I now need much higher resolution, I am in the market for a 17" which I'd buy with an SSD (the 256 GB Toshiba in my configured online 13" MBP is perfect to me). Some more CPU power is always welcome (i7 vs i5) but a difference under 20% does not really matter to me, some more battery life is welcome too (15 vs i7) but I dread, no, *I hate heat*.
Are the Notebookcheck measurements credible?
"+Even if the i5 processors have a slight lead in many exercises in terms of performance, the i7-620M CPU reveals itself as being especially energy devouring. The CPU treats itself to about 15W more, with up to 64.7W under load, than the i5 colleagues. The test system also needs around 10W more in idle mode with 30W than the configuration with a Core i5 chip.+"
Should I try to find an "old" 2.8 C2D 17" and buy an SSD separately? What are your experiences with heat from i5 and i7 in 17" MBPs?
I've had My MBP i7 for about 4 Weeks, and have found its _battery life to be EXCELLENT!_
I would say I am an +average user+ who would normally use the Computer running a few Safari Windows, MSN Mac, Mail, pages and sometimes, VMware Fusion with Windows XP Pro, Microsoft Word, as well as GarageBand or iMovie too.
I do have breaks where the computer is 'Sleeping' for about an hour.
My Screen is Set to 50%, Bluetooth is off, but WiFi is constantly on.
I found that i get about *6-7 Hours use* with all of this and *Multi-tasking is never a problem with the power of the i7.*
I have not had experience with the Core i5 so I can't advise you there.
