How long do you get out of your battery?

For the past few weeks I've been planning on getting a Mac notebook. I was originally set on the idea of an iBook but I'm tired of waiting! So this evening I sat down and analysed the iBook vs. PowerBook situation, comparing features, prices and price differences (taking into account education discount).



Basically I've come to the conclusion that for the price, I'd like a 15" PowerBook with combo drive. However I'm a little concerned about the battery life. The Apple web site reports 6 hours for the iBook (12 and 14-inch), 5 hours for the 12-inch PowerBook and 4.5 hours for the 15-inch PowerBook.



Now, I know it does depend a lot on what you do with the machine. However I've seen reports (on various different forums) of people getting about 2 hours out of their PowerBook and hence my posting.



How long do you get out of your PowerBook 15" and what are you doing to achieve such results?



How long do you get out of other 'Books from Mac and what is your configuration?



Portability is not a big factor with this purchase, but battery life is. I can analyse spec vs. price by myself on paper, but you cannot really analyse battery life!



Thoughts?



Cheers

    My 12" iBook goes about 4 hours on normal use with screen close to max brightness.

    i have a an older titanium PB, and a brand new battery for it thats compatible w/ apple PB's, and i can squeeze 3.5-4hrs in it usually depending on how much use and what im using it for.. when i use music as well... the battery life slows, and drains faster the more you need the batter and such the shorter charge youll get out of it.. but 5-6hrs on a charge is nt known, atleast to my knowledge... good luck... btw: im liking the PB, was going to buy an ibook, but then i got the powerbook from my brother and im loving the powerbook

    Yeah. I have been getting about 2.5 on my new 15". I thought there was something wrong with it but apparently that is the norm. I am using the default settings.



    I also have a first generation TiBook (mostly used by my wife). I bought a NewerTech battery for it and now it gets about 3-3.5 hours. I don't know how much of that difference is the battery vs the machine.

    Pismo and a 1 1/2 year old battery: 5 - 6 1/2 hours.

    Same here on my iBook G4 1GHz, although it was slightly more when the battery was fresh... no complaints on the battery life but I wouldn't want to sacrifice too much.



    Hopefully when we get Intel CPUs in Powerbooks and iBooks, the battery life will be substantially improved. I'd be quite happy with 8 hours

    8 hours? that'd be nice... im getting a lil bit less then half of that... im happy

    I get about 3 hrs on my 1.33 15" AlBook, that's with the screen on full and airport on, just browsing and stuff.

    With my old 1Ghz iBook i would get close to 5 hrs with full brightness and airport on doing the same stuff.

    The iBook had 768Mb and the PB has 1Gb RAM so I suppose that helps in terms of keeping the disc activity down and saving power.

    prolly... but what i need my laptop for, 3-3.5 give or take .25 worth of time is enough for me.... notes, surf web, chat client to satisfy boredom in classes....

    Do you guys all use Reduced CPU performance to get these times?

    Nope, I just use "Automatic." Seems to do the job. I think more efficiency comes from reducing TFT brightness. The iBook's G4 has to use next to no energy, since it appears to be passively cooled.



    I'm not sure if Tiger or Panther has better battery life. I do like Tiger's quick powersaving pull-down list next to the clock.

    My iBook G4 1GHz has a fan... surely your iBook does as well.

    nope... my screen is on max brightness, and im usually just surfing and ichat, sometimes i do like MS apple word stuff.. some photo-shop./.. but i usually save that fun for my vicki (my imac)

    the ibook DOES have a fan but it usually idles very low making it almost silent. If you run the apple diagnostics, it spins it up to full speed for a few seconds to test it out. then you can hear it. but yea, its very quiet.



    all i do on my ibook is surf the net, chat, write papers/programs, and other basic stuff like that.
