Microsoft Tests Show That Windows 7 Doesn't Affect Battery Life

While hundreds of notebook users have been grumbling about battery issues pertaining to the three-month old Windows 7 operating system, Microsoft has claimed that its extensive testing has shown that its OS wasn’t at fault.

As reported last month, many users have asserted that they have observed considerable decrease in battery life after they upgraded their notebooks to Windows 7. The complaints included a new advanced Windows 7 tool tailored to indicate the user when their notebook’s battery needs replacing.

In some of the cases, the message “Consider replacing your battery” was being displayed even though the notebooks had brand new batteries.

In a Monday blog post, Steven Sinofsky, Windows and Windows Live President at Microsoft, noted that the operating system has been working as expected.

The software maker and PC manufacturers have received 20 support enquiries related to the battery issues, and all of which have had older or degraded batteries as the root cause, Sinofsky said.

According to the blog post: “To the very best of the collective ecosystem knowledge, Windows 7 is correctly warning batteries that are in fact failing and Windows 7 is neither incorrectly reporting on battery status nor in any way whatsoever causing batteries to reach this state”.
