10.2 Battery Life?
Anyone with a laptop (iBook 500 here) and 10.1 knows OS X isn't great for batteries in laptops, since none of the OS 9 Energy Saver options are implemented, for example. (I like to control my computer, thank you)
I was wondering if battery life while sleeping and in use has improved? I literally watched OS X eat my iBook battery from full charge to nothing, at 2% a minute, NO KIDDING. :eek: I wasn't doing anything stupid like burning a CD, in fact I was doing next to nothing. And this problem is magnified when you consider how much waiting you do in OS X on an iBook. So anyone out there with 10.2 on an iBook see a battery life or Energy Saver improvement? Thanks.

does eat the battery quicker in sleep than 9 but it also wakes up instantly. a trade off that some are willing to accept and others aren't
I can get 2-3 hours on 10.1.5 surfing with Airport and listening to iTunes. I'm pretty happy with that, although more is always better.
Disable the feature that "Enable machine to wake up by Network Administrator", sorry, I am on a public machine running Windows, I don't exactly remember how the wording should be read.. You will have a much better battery life as well as OS 9 while sleeping.
That should help us with portable computers a bit. Well, ust two more days of waiting now.

It is good to hear Advanced Energy Saver options are back. Applenut you are right, OS X wakes up much faster than 9, but the incredible battery suck isn't worth it IMO. There must be a way to avoid that trade-off?
I will have Jaguar installed tomorrow night, and will try to get a post on here regarding the difference in battery life on Saturday.
<strong>No one with an iBook has weighed in. No doubt X's eye candy taxes the G3. Also, 2-3 hours of battey life is NOT what Apple advertises That's fine, for a Wintel POS, not an Apple.

A bunch of people claimed 3-3.5 hour battery life with their iBooks. Read more carefully.
<strong>one thing that will give you a good amount more of battery life is to turn down the brightness on the screen.</strong><hr></blockquote>
[b]dartblazerp/b] hits the nail right on the head. I am running an iBook/500. With the screen brightness down to two or three bars, I can get nearly four hours taking notes in class. I don't let my HDD spin down either. Leaving screen brightness all the way up, battery life decreases by almost half, to a solid two hours.
I was lucky enough to get Jaguar from Apple today (Thursday). I still can't believe it. In any case, I am delighted to see the complete Energy Saver control panel return. Now I can finally enable processor cycling (reduced clock speed) when I'm running my iBook on battery. Hopefully this will improve battery life quite a bit. I have four classes on Monday, so I'll have real life results in a few days.

<strong>Boy, I'm not impressed with you guys' battery life. My TiBook 550 gets about 5 hours on a charge reading the net in the evening with the screen brightness way down (OS 10.1.5). Turning brightness to full does reduce battery life by about half. 2 1/2 hours at full brightness or 5 hours at minimum seems damn good to me. Is there a Windoze machine that can do this?</strong><hr></blockquote>
Only sub-notebooks with Transmeta processors or a 500MHz super low power PIII.
-What system were you using?
-What were you doing?
-What were your Energy Saver settings?
iBook 600MHz 14inch
Brightness turned down to next to lowest notch
I get 5 and a bit hours while listening to iTunes 100% of time, reading/writing word files and some net browsing.
I would say thats pretty damn good.
Sorry, but havent had the opportunity to try out 10.2 and battery life yet. All I know is that I cant complain much
