Latest upgrade looks like its hurting MacBook's

According to reports from Macworld, many users that have upgraded to Apple's latest operating system, Mountain Lion, have been reporting that the upgrade has seen a sizeable drop off in battery life in their MacBooks.

A poll by Engadget shows that more than 8,000 (43 per cent) of the 18,939 respondents that had downloaded OS X 10.8 Mountain Lion noticed a difference in battery life immediately.

A second poll from Razorianfly showed that 77 per cent of respondents are experiencing shorter battery life with Mountain Lion. The poll also revealed that the problem is most common on 2011 MacBook Pro models.
