Tests Find OS X Mountain Lion May Significantly Degrade Notebook Battery Life

[Benbikeman]

Option + Click the Notification Center icon in the menubar (this disables notifications) made my battery life back to its Lion state.

No change here.

Looks that the problem is the Notification Center. Check it by yourselves.

checking it out as soon as I get mine charged up ... will see how it goes ...

thanks apple

I just had an unsolicited call from apple based on a post in their support forums.mi haven't even installed ML, decided to wait until they fix the battery issue. without admitting they have a problem, the rep said they are following the threads carefully and began calling people within a week of the release. so they are aware and working on it.

For those wishing to roll back to Lion only to find that the reinstallation process puts ML back you need to hit alt+cmd+r at boot up - this reinstalls Lion. cmd+r reinstalls ML.

No, I have 16Gb of RAM and see no swapping at all, yet my battery-life has still just about halved.

Jeez. I have 8GB and Safari eats 4GB within 1 hour and kernal_task will eat the other 4 soon after. Nothing has changed about my habits or usage other than Mountain Lion's propensity to destroy RAM about 4x as bad as my Lion did -so i figured that may have something to do with it, but I guess not.

I've noticed it dropping faster

You sure?
It automatically gave me +1hour of battery life.

Wowzera! Your deviant account is deactivated. Time to change your sig?

Everywhere I go there's plenty of A/C outlets. So the battery issue is no big deal for me. I'm more than happy to wait until Apple has a fix. I have no desire to roll back to an earlier OS.

Trying that. Great tip, thanks, I didn't know how to disable the notification center.

I am not a huge fan of it on iOS but on OS X it's even more useless.

Actually - this disables it until tomorrow, so I guess have to do it every day...

Definitely no improvement. Running nothing demanding, and with no abnormal CPU usage, it went from 98% charged to 78% charged in half an hour! So whatever it is, it's not the notification centre.

Haha, I miss my dA account I'll leave it in my sig to remember the good old times!

Some people report it does not help them, but it help me to get around ~1 hour of extra battery life (not as good as Lion performance, but still better than Mountain Lion with NC).

Mine does not work this way, I see a real improvement. Looks that the problem is even deeper. Hope Apple fix it asap.
