A new report is suggesting that the next update that will be released for OS X 10.8 Mountain Lion will address some of the issues that some users have been experiencing with reduced battery life in various MacBook models. According to Softpedia, an update will address the original issue whereby some users who installed Mountain Lion were observing greatly reduced battery life compared to what they had been used to when running OS X 10.7 Lion. So it looks like Apple has been working on the problem and appear to have fixed it.
Apparently, the latest build of 10.8.1 that has been seeded to registered members of the Apple Developer program for testing actually contains fixes that improve the battery life, so that it returns to normal consumption. That said, Apple has not acknowledged the problem, and it’s unclear what the source of the issue actually is.
However, since Mountain Lion is a .0 release (meaning it is brand new), a .1 release should hopefully fix most of the major issues, if any, that users have been experiencing with the new operating system.
