OS X Mountain Lion Users Report MacBook Pro Battery Issues

Just a couple of weeks following Apple’s release of its OS X 10.8 Mountain Lion, a lot of MacBook Pro and MacBook Air owners reported that their devices are having battery life issues after installing the new operating system. There were also users who reported that their notebook’s battery only last half as long as when OS X 10.7 Lion was installed.

Battery Life Drop Issue on Mountain Lion

The first complaints with regard to the issue first appeared on Apple Support Communities last July 25. Up to this moment, the number of affected users has grown to the point where the company is supposed to initiate investigation.

Some users are seeing their device’s battery life drop to about an hour or two, while some owners claimed that their notebook’s performance has fallen to less than 50 percent. That’s because their machines are only capable of staying for a little over two hours.

In relation to this, community members have been trying various methods to remedy the issue. Some re-installed the new OS, while others turned off some of the OS X 10.8 features. However, these attempts are yet to produce a fool-proof solution. There were also users who have seen limited success in resetting their MacBook Pro and MacBook Air’s system management controller. That’s because the battery crops up again after continued use.

On the other hand, there are complaints of heightened CPU temperatures even when the machine is idle, which points out to a backend program management problem. Also, there are users who reported that the notebook’s battery continue to drain even while the machine is in sleep mode.

OS X Lion vs. OS X Mountain Lion

The battery issues that OS X 10.8 is encountering reflect the trouble that its predecessor had when it was released last year. Tech and gadget website, AnandTech, also posted a review last year regarding OS X 10.7’s battery life performance:

Battery life on the Sandy Bridge MacBook Pro improved in two lighter workload tests by 5%, however under heavy load there was no change. Given that we only saw improvements in our two workloads with built in idle time I suspect Lion may have tweaked some power management settings vs. Snow Leopard, but nothing more.

On the other hand, the problem is still unresolved for many users of OS X Lion.

Apple has taken notice of the issue, and one community member reported that the company sent out a questionnaire last Friday to point out the problem. Packing over 200 new features, Apple’s OS X 10.8 Mountain Lion was released last July 25.
