Mac OS X 10.8.1 Improves, but Doesn't Solve, Battery Life Woes

The good news for Mac users is that battery life is improved with Apple's OS X 10.8.1 update, which attempts to address one of the biggest complaints with Mountain Lion. Unfortunately, tests around the Web show that battery life is only marginally improved, in some instances only adding two minutes of additional run time.

In depth benchmarks from The Mac Observer show what can be expected with a heavy workload, and the result is that while OS X 10.8.1 offers better battery life than 10.8, it still trails 10.7.4 by 78 minutes.

Mac OS X 10.8

"The battery life hit caused by 10.8 Mountain Lion is significant," TMO wrote. "Our 2011 MacBook Pro lost 2 hours and 10 minutes, or 33 percent, of battery operating time following the upgrade. Remove the Wi-Fi icon from the menu bar had no positive impact (in fact ,we actually lost 5 minutes of battery life)."

Similar tests from other sites reveal the same thing -- Mountain Lion is a bear on battery life, at least for now. Apple is said to be testing a new iteration, OS X 10.8.2, though it's unclear if battery life remains a focal point.

The battery life on mac products has always been a huge selling point, if the new update that makes the system more functional also kills the battery life then mac is killing some of its appeal. They need to either rework the system or boost battery life significantly to compensate in future models.

The OS is still young. Give them some time and they'll resolve it.

Why do an update when you cant solve the most critical issue? You knpw why? Because in apple its all abot "values"

This happens in all iOS updates. Updated my ipod touch after years and battery life immediately went down by a few hours at the very least. Few friends updated their iphone 4 to w/e OS that was released a few months ago and then complained about battery life going down and now this. Doesn't anybody at apple test this before releasing the update?

I'm sure they test it but they probably figure it's worth the risk rather than delaying the release. All software development makes these kinds of decisions. There's no way they don't know about these types of things during the test phase.

Somehow get the feeling that customers are bearing the brunt as in 'consumer test pilots' with this one one .

As I have said elsewhere it is a demographic in general that will bear the brunt of this with a little whining maybe but basically that is all. I personally think we as American citizens should sue APPLE for trying to contain real world technology development with there patents. Yes I understand if you have a real innovation you want to protect that but a rounded edge and a "specific" way to pinch and zoom really!
