Following Apple's Mountain Lion operating system update, it appears it adds battery life for MacBook Pro with Retina Display owners.
As Latinos Post reported last Friday, the OS X Mountain Lion update version 10.8.3 includes more than a dozen improvements and enhancements, including:
- The ability to redeem iTunes gift cards in the Mac App Store using your Mac's built-in camera;
- A fix for an issue that may cause audio to stutter on 2011 iMacs;
- A fix for an issue that may cause the desktop picture to change after logging out or restarting;
- A fix for an issue in Messages that may cause messages to appear out of order after waking from sleep;
- A fix for an issue that may cause the screen to display incorrectly after waking from sleep;
- Reliability improvements when using a Microsoft Exchange account in Mail.
But in addition to the before-mentioned items, Mac Observer has noticed a battery life increase with the 10.8.3 update on Retina MacBook Pros.
Back in September, Mac Observer tested the battery life of the 15-inch MacBook Pro with Retina Display following the update of version 10.8.2. The result was 383 minutes, or six hours and 23 minutes.
Now with 10.8.3 rolled out, Mac Observer tested the 15-inch MacBook Pro with Retina Display's battery life again, and the result was fairly good news.
The battery life has increased by 23 minutes.
"While the extra 23 minutes of battery life is not a huge improvement, it is a nice bonus for [MacBook Pro with Retina Display] owners and notably gives the product the advertised '7 hours' of productive use for the first time in our testing," reported Jim Tanous.
