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."

I don't know about notebook users, but when I purchased and installed Vista, Aero was not initially running. I had to go select it from the Themes area of the Display control panel.
So when they write the following:
Seems like more of an issue with educating users. Although, maybe someone will develop a miserly mobile GPU that's optimized for what Aero does.
Finally, this part of the article is a bit screwy:
I don't think the study implies that. It just says that application load time is unaffected. Aero's going to draw more power through the GPU even when applications are not being loaded...

So everyone who bought a PC for christmas and got a Vista voucher is also counted in that list. So all those Vista Business sales only got counted in the first quarter.
PC sales are down, how can Vista Sales be sky high? maybe because MSFT counted 1.5 quarters of vista sales in one quarter. what they did is technically legal, but one can't judge Vista sales by it because of what they did. As it artificially inflates the numbers.
Lets see who they do in this quarter. Especially with Dell selling XP machines again.

I am now running LongHorn Server Beta 3 on my notebook, running as a standard user. Glass and Sidebar are not even available, and my battery life seems to have gone up significantly, I assume because fewer processes are running. IE is hardened on server and it is certainly more secure. And yes, I have enabled the wireless functionality and search indexer. My desktop does look much like Win 2K.
Security tends to go up as you run less functionality. It appears that battery life does so as well.

The Default Power Settings Disable Aero (Score:3, Informative)
The "power saver" profile turns off Aero, although keeps desktop compositioning enabled. (I think.)
The article wasn't clear on whether or not it was the Aero theme (with all the pretty transparencies) or the desktop compositioning, that was causing the power drain.
Re:No suprise here - same for XGL or AIGLX (Score:2, Informative)
If indexing is your problem, you misconfigured your power settings. By default, a laptop should do little or no indexing while running on battery power ("Power Saver" mode). Assuming you didn't go monkeying around with your power settings, setting them to "High Performance" on battery power, you're probably seeing something else like Defender scanning for spyware or your antivirus scanning for viruses. Personally, I'd turn off real-time protection and just do periodic scans while running on wall power, but that's a question of "security" vs. battery life (I'd choose battery life).

the drm which is in there left and right adds additional processor cycles
Look, I know that DRM is really unpopular, but could we not have absolutely ridiculously stupid assertions like this that DRM is affecting everyting "left and right" and is somehow running down the battery in a noticeable way?
Sheesh.

First off, it's a desktop, measured at the AC adapter. If a standard laptop took 150W, then the battery would only last 20 minutes. Clearly, laptops take less power overall and the differences caused by the CPU's load will be amplified.
Second, it measures the power at only two points - no load and full load. I suspect that no-load between XP and vista is about the same because they are basically doing nothing. You need a real-use benchmark to compare the two.

Here is a quote from Paul Thurrott's analysis [windowsitpro.com]:
So despite the best efforts of many people in the media, and certainly Slashdot, The Register, and similar anti-MS sites, Vista has done extremely well. My bet is that it would have done even better if all this FUD wasn't being spread.
Maybe, just maybe, you're all wrong about Vista. Maybe, just maybe, Vista is a really damn good OS. Stop regurgitating the FUD and try the OS for yourself.

The assumption that Microsoft products are always insecure is not justified. Microsoft consumer products are feature loaded and are optimized for rich usage models. Consequentially, they have far larger attack surface than if they were minimally configured. We see the same thing hapening in the *nix releases. Ubuntu and SUSE are far larger than *nix releases of 5 years ago. Compare them and their requirements to the current BSD releases, which are far more economical. Field experience with Windows 2K3 servers has shown them to be quite secure and very reliable. I believe that this will continue to the be the case with LongHorn server, which I have been running on and off for 2 years now, from early pre-beta releases. Unlike the early builds of Vista, LongHorn server has been robust and reliable. Vista accomplished this by RTM, but LHS has always been solid in my experience.

First, I run Vista on three machine, my laptop, my desktop, and my work machine. My laptop is an IBM T42P. Not exactly the fastest machine on earth. (1.8 Ghz, 1GB of ram, 128MB ATI FireGL 2) It runs Vista faster than it ran XP... or, rather, it "feels" faster thanks to things like Readyboost. My "Windows Experience Index" is 3.8.
My desktop is over 2 years old (3.8 Ghz, 2GB of ram, ATI Radeon X850XT), and it runs Vista blazingly fast. The index on this machine is 5.2.
My work machine is a crappy Dell Precision 360 that's about 3.5 years old. It has 2GB of ram, 64MB graphics card, and 3GHz CPU. Vista runs great, and has an index of 4.2.
So there are three machine, all of which are between 2 and 4 years old, and all of which run Vista just fine. Only the work machine doesn't do Aero due to a non-DX9 graphics card.
But that's just my personal experience. So why not look at some real benchmarks [techgage.com] done by 3rd parties. They show that Vista is comparable (slightly slower in some cases, slightly faster in others) to XP on the same hardware. In most cases, the benchmarks Vista does worst in are gaming benchmarks. Although we're only talking about 1-2% in most cases, these can be explain by immature drivers. Give it a few months and those drivers will likely be up to par with XP's.
Again, there is a LOT of FUD out there. I can see why it would be hard to sort through.

Do you have any fucking clue how DRM works on Windows Vista? It's not some magical happy service that's running all the time. It's integrated into the kernel and into Windows Media Foundation and the Windows Media Framework. Of course, it's integrated into the Kernel and Windows Media Framework on XP too.
XP has many of the same DRM and DRM-esque features as Vista (WGA/Activation, Secure Audio Path, Windows Media DRM, Signed drivers, ICT support). Try playing an HD-DVD on XP with a licensed player and a card/monitor that doesn't support HDCP. Try playing a Region 2 DVD on an XP system where the RPC1 or RPC2 region has been set to Region 1. Try playing a copy of T2 Extreme HD on XP without registering it.
Yes, there are new DRM technologies in Vista. But just like the DRM features in XP or - god forbid - Mac OS X, the solution is obvious: don't buy into bullshit DRM.
I don't have an HD-DVD drive for a very good reason - I don't want to put up with bullshit DRM. Once the DRM has been cracked (truly cracked - not just cracked for movies released prior to date X), I'll consider getting a drive. Until then, I watch plain old DVDs using VLC and my region-hacked drive.

When it DOES work it looks absolutely beautiful, and completely blows away anything that Windows or OSX has to offer. Is it going to stay on my machine? No, it's not, but It's a project I'm going to keep a very close eye on. OSS developers are just as capable as the proprietary vendors in creating useless eye candy, I've probably spent 20 minutes rotating that cube.
I dual boot with Feisty and Vista (ultimate) and the battery problem IS real. Ubuntu gets about a half hour of extra battery life on this laptop than when I boot into Vista (even with Vista in feature cutting power saving mode, although I'm not using Beryl for the Ubuntu comparison, I'm not sure what things would look like with all the eye candy turned on.)

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?
Probably because Aqua and X are more efficient than Aero and all the DRM nonsense that M$ has put into Vista. You don't have to do the user any good while you spin their processor. Enlightenment, KDE and Gnome also have nice eye candy without cost to battery life.
