Vista Battery Life Issues?

Though I’m still living in the land of XP, I have noticed a good bit of buzz lately about how Vista may or may not affect battery life. GottaBeMobile.com reports that Motion is delaying the Vista LE1700, possible because of battery life issues:

Motion Computing has been informing their partners this week that Vista based LE1700 Tablet PCs will be delayed until July 31. Here is the message that was sent to their partners and also posted in the GottaBeMobile.com forums :

Motion has postponed the shipment of Vista on the LE1700 to July 31, 2007 to allow time for further testing. Recent industry-wide testing of Vista has revealed critical errors that Motion has also observed while running Vista on the Motion LE1700. Although this postponement is very disappointing, Motion has made this decision to ensure a stable Vista environment for our current and future LE1700 customer base.

From CNET News.com:

Some of Microsoft’s most important customers aren’t happy with the battery life offered by notebooks running Windows Vista.

“It’s a little scary,” said John Wozniak, a distinguished technologist in Hewlett-Packard’s notebook engineering department, referring to the work HP needed to do on making Windows Vista more suitable for notebooks.

Brandon Paddock assesses the article, pointing out a critical error:

While I’m the first to agree with the fact that the out-of-the-box power settings are not ideal for my uses, I don’t think the article was particularly fair. For example, they didn’t even bother to cite actual battery life comparisons – nor compare the default power settings from different OEMs.

However, there’s a notable error in the article:

The Aero interface is automatically disabled when users put their Vista notebooks into the “power-saving” profile, one of three new simplified power-management states.

That is not correct. Switching to “power-saving” profile will disable transparent glass only when on battery power. That is not the same as disabling Aero by any stretch.

From my perspective at least, the flurry of posts started on GottaBeMobile.com with Rob Bushway’s “Microsoft, lets start an open conversation on Vista and battery life”

Over the next several months, I plan on taking the issues I raised and addressing each with its own focus with the end goal of bringing about positive change in the space. The first issue I’d like to focus on is battery life and Vista.

and continued with Warner Crocker’s “Vista Battery Life Conversation Heats Up”

Rob Bushway’s editorial yesterday about battery life woes for mobile users running Vista has sparked quite a bit of conversation. And as usual on the Internets, some of the talk can get a bit wacky. Apparently one meme in the thread has info reporting that the Aero interface is automatically disabled when users run under “power-saving” mode. As Rob pointed to in an update, Microsoft’s Brandon Paddock weighed in with a rebuttal to that point[.]
