MacBook Pro and MacBook Air users are reporting battery performance issues after installing the latest Mountain Lion operating system.
The thread on Apple’s Support Community discussion boards titled “Battery life dropped considerably on OS X Mountain Lion” runs for 30 pages on the Apple website.
There are also several other similarly named threads discussing the same issue.
Most are reporting battery performance drops of about one and two hours with some reporting battery life has more than halved since installing the new record-breaking Mountain Lion operating system which was launched on July 26.
Suggestions from community members have ranged from turning off some of the new features found in Mountain Lion – including Power Nap which performs updates in sleep mode – to completely re-installing the software.
Another suggestion was resetting the Mac laptop’s SMC (system management controller) with users reporting only limited success.
Apple has reportedly launched an investigation into the issue that may be then remedied with a software update.
