Vista Eating Battery Life 379
LWATCDR writes "It looks like more issues with Vista drains notebook batteries. Using the Aero interface really eats into your notebooks battery life. Of course one of the new 'features' of Vista is supposed to be better power management. This provides a great opportunity for a showdown. How long until someone loads Vista on a MacBook and compares run time? It would provide a flat playing field now that Apple makes Intel-powered notebooks."

At least last time I tried to run Vista on my MBP, part of the problem was Apple drivers that weren't optimized for power saving. The processor ran at full speed all the time (where on OS X it used SpeedStep) and the HD would never spin down. Thus I don't know how much of the fault is Microsoft's and how much is Apple's.
With that in mind, I got about 60% the battery life from Vista that I got from OS X.
Still, though, OS X's decent battery life gives the lie to the idea that "it's a processor-intensive process. Duh." If the Aero interface is eating battery, then why isn't Aqua, which is just as full of eye candy?
Mac Notebooks Battery Life rules (Score:4, Interesting)
Everytime I've used an iBook or a Powerbook, I'm amazed at how long the battery lasts. While some other brands (e.g. Dell) have decent battery life compared to others (e.g. HP and Toshiba, at least in my experience), I'm always knocked off by Apple notebooks' battery life.
Now if only Apple notebooks had two mouse buttons instead of hacks around it.

Also, Apple laptops seem to treat batteries better, at least from my anecdotal experience. Most of the Dell/HP laptop owners I know end up with horrible battery life after not that many cycles. After the same amount of use, my Mac laptops have typically only lost a bit of their capacity. (My current MBP with 180 cycles on the one-year-old replacement battery has about 90% of its original capacity.) Whether this is due to better power-management software, better battery design, or better battery cooling, I couldn't say.
As for the two mouse buttons, it was a problem until Apple came out with the two-fingers-plus-click move last year -- now I definitely prefer that to a physical second button, because the huge first button is still so easy to hit and I never accidentally right-click.
Bad Drivers / Hardware? (Score:4, Interesting)
Since it actually puts your video card to good use, Aero makes things faster, not slower. Would you want your fancy game to use some generic CPU instead of all the specalized functionaly provided by your GPU? Why should your OS be any different? Unless your hardware sucked, you would be a fool to turn Aero off--it just makes your CPU do more work!
What this power consumption business really means is hardware manufacturers need to optimize the parts of the GPU that Vista uses so they consume less power. In a year, new "Vista-Ready" laptops will probably use the same, if not significantly less power than their XP optimized counterparts. Less power you say? Hell yeah! Vista has all kinds of goodies for power management that didn't exist in XP; my desktop computer now suspends itself to... something.. after 5 minutes and will instantly wake up. Dunno if XP could that, but it sure as hell didn't on mine. It was default behavior on my Vista install.
Further, Aero is definitly not eye candy and I'd even argue that it is the first version of Windows that *doesn't* have eye candy. The user interface is crisp, snappy, and far more elegant than anything before it. You barely notice the OS is even there; XP & 95 are very "in your face". I personally love Vista - I dare say that when running on proper hardware it really makes you feel the PC has come of age. All prior windows versions feel clunky in comparison.

I get approximately 30-45 minutes (unscientifically tested) more battery life from OS X.
What boggles my mind the most of all is that Vista has no provision for automatically disabling the Aero interface based on the power source. I'm sure the power disparity would go away if Aero would disable itself as soon as I switched over to battery power. As example: I can hear a fan (presumably GPU) kick into high gear just sitting on the desktop doing nothing. To me that is completely ridiculous and Microsoft should be investigating a way to fix it.

I read these "reviews" online, which are so completely off base and inaccurate, I'm not surprised so many people think Vista is a steaming pile.
But the fact of the matter is that virtually all of the complaints about Vista are easily debunked. Whether it's the DRM FUD, the performance FUD, the "Vista is just a pretty face on XP" FUD, the "UAC is popping up CONSTANTLY" FUD, or any of the other baloney I've read.
Is Vista perfect? Hell no. But the minor issues it has are dwarfed by how much better it is than XP in virtually every way.

The P7230 is an ultraportable laptop with incredible battery life. If you fill both battery bays and enable CPU frequency scaling, you can run it for 8 hours without plugging it in. In Vista without Aero (which this machine can't really handle anyway), I would get up to 11 hours of battery life. In Ubuntu I can maybe get 9. I still use Ubuntu full-time, but don't tell me that Vista has worse battery life. Turn off your useless eye-candy if you care about your battery. I'm sure beryl would kill my battery life even worse.
