Q: Battery life dropped considerably on Mountain Lion.

How do you have disabled the notification center ?

Manueru

Did you disable completely in Terminal? I have it temp disabled and noticed some improvement on a late 2008 MBP running ML.Debating whether to disable it with the terminal command. Let me know.

I did it through the terminal.

Open the terminal and type

cd /System/Library/CoreServices

sudo mv NotifyCenter.app NotifyCenter_Disabled.app

killall NotificationCenter

Nope, switching Notification center off has not resolved the issue. I believe this solution would be to obvious for Apple developers to check it at the very beginning of having first complainings.

At least this solution does not work for my MBP middle of 2010. It worked 3.5 hours with Lion.

With ML 10.8.1 it hardly works 2 hours. Drops 1% per 1 minute.

Thanks Done now to see how it helps. MPB has been on since this am, standing at 57% with some use and sleep. Can always re-enable so no harm no foul.

Thanks ! I'll see if it helps my Retina.

So, how long is your  battery life lasting wih Lion, and are you happy with Lion battery life?    

Has anyone tried running  'ps aux' in the terminal to see what processes were consuming the most CPU?    

Maybe try ps aux |grep .com. 

to see what objects are running in the background which you can dissable.

Beisarius,

Thanks for the details and the reasoning on what you selected. Really appreciate being able to see your real-world experience on what you're seeing for battery life.

It's all speculation of course, but it's easy to wonder if this is more about a variety of issues; different tweaks seem to help some people on some machines more than others, and even reports about 10.8.1 seem to vary. Hopefully they'll get to the bottom of it.

Have to say I'm disappointed in how Apple is handling this, especially given it's affecting users of current models and Apple controls the whole ecosystem. If someone was encountering the problem on some weird / ancient / non-Apple configuration that's easier to understand.

But for people with brand-new models to be seeing the issues makes it seem more serious--like that Apple needs to improve their testing procedures. Part of the reason we choose Apple and pay the premium is because "it just works." Mountain Lion so far doesn't meet those expectations and makes it much easier to consider alternatives. Even though I'd much rather stick with OS X.

I said b4 on page 86 and showed pictures of istat and apple battery on top dock and i had 2 and little more hours battery life at full charge while installed also the battery health app of mac appstore showed me 7 and more hours, then what i did is i recovered my installation not fresh install keeping my apps installed and did the update again to 8.1. It shows now 9 hours on the top dock and more than 8 hours on istat and battery  health app shows also over 8 hours

Helle Apple.

Do you really think, thats the normal way for a 1200€ Maschine?

My only "work" was taking these pictures....

After 10.8.1 I have left my MacBook Air sitting asleep whilst on battery power for two day just opening occasionally to check and battery has stayed around 75% to 80%

Opened it up this morning at 73% started Safari ... just opned it and have sat here for 15 minutes or so just watching battery dissipate over 15 minutes with no use it's dropped to 61% that's way too much when not even in use.

Is it tru that this problem destroys battery health permanantly and will Apple replace the Batteries if so ?

Can everyone on the thread restart their machines and try pressing 3 and 2 during restart?  This will put the machine back in 32 bit mode.  I tried this, and saw improvement. 

Why would you want to run the machines below capacity that's not what I bought it for ... problem has to be fixed by Apple not delet stuff turn stuf off and not use functions you paid for .... what's the point of that ... buy a porche and reno it down to a toyota ?
