New rMBP Battery Life With Parallels 9

If running Parallels 9 with Windows 7 or 8.1, how much battery life is expected for the new Haswell rMBPs? I'm assuming normal tasks in Windows and not gaming and with 3d disabled.

This is referring to the 16gb model so I'm guessing it shouldn't run into swap issues much.

This is very important to me since I'd run Parallels in Coherence mode most of the time for some Windows specific poker programs.

I also wonder if the fans would stop being silent even if Windows isn't doing much.

I really appreciate feedback on this even if it's the older rMBP.
 
I tried parallels but switched to fusion - too many issues and errors with parallels.

but in battery terms parallels is a step in front of fusion.
 
I haven't had those issues with Parallels and enjoy the better integration so I'll probably stick with them. I have tried Fusion in the past too but at least then, the performance wasn't on par.

So how much battery life do you get with Fusion vs regular and vs Bootcamp?
 
Bump!

Also, how much battery life would a Boot Camped W7 get on the new rMBP?

Thanks!
 
I tested VMWare 6 with my rMBP15'' (Haswell w/ 750 on).
Windows 7 with Excel 2013 - 2:58 hrs remaining
it won't let me use iGPU on VMWare 6.

Case in point. Running Parallels 9 is like leaving Photoshop to render something in the background the entire time. It takes a lot of resources to make Windows run at all, let alone as well as it does. And on top of that, Coherence mode will only exasperate the problem.

There is a way to minimize battery use and heat generation. I HIGHLY recommend you chock out gfxCardStatus for your Mac. It allows you to force exclusive use of your Mac's (more than adequately powerful) integrated graphics, to reduce power use and heat generation.
 
15" Retina 16GB 750m, Win7
MacOs: 8 hours (Reading, writing, surfing)
Parallels Coherence: 5 hours (Citavi and Inforapid-Knowledgemap)
 
What would be the best comparison parameters for typical usage for parallels vs fusion vs bootcamp?

Let a YouTube video play in safari html5 on a loop for media test.

What about web browsing? Auto refresh a site every 5s until dead?

And some sort of office usage model, like converting XML to csv in excel repeatedly?

I bet if we could come up with the proper parameters someone would test it. =)
