If the new rumour is true - what's the deal with battery life of the mbp?

Some are saying that, if the rumour hold's up, that the mbp battery will never live up to it's 7 hour+ reputation.


Now i don't understand ampage, wattage, performance, and gigga jigs etc. I'm just a user, not a techie.

But battery power is important to me.

If all that we're supposing is true, will the battery power be suffering?

thanks in advance :)
 
What new rumor(s) are you referring to?

Battery life for individual users will always vary widely based on how the computer is used

thanks mac dawg, good to hear from you!

I'm primarily referring to the rumours that are now circulating in the unofficial arrandale thread
 
battery life is not that important to me cos i plug in the adapter all the time

you can buy my MBP then. Very disappointed with battery life (first gen unibody MBP). I lust after a 7 hour battery. It could keep my toasty warm all evening long on the sofa :p
 
I heard that the new battery will be over 9000 gigga jiggas, which works out to be around 9 tebbi jiggas.
That should be a 1000 gigga jigga improvement over the previous battery so it should help the battery last even longer than before :)
 
I think, battery life will stay the same or increase a little due to simple marketing- going back is not an option here.

This generation of Arrandale CPUs is not Power Optimised, yet.

Battery life is around the same or better than the previous generation of Core 2 Duo.
The key thing is the GPU. Apple may choose to include the ATi 5830 which is 1W higher than the 9600GT but brings massive performance increase. It shouldn't dent the overall battery life too much though.
 
my 15" MBP unibody lasts 5-7 hours consistently, surfing the web, listening to music, wifi on, and the occasional youtube video, or word document. Love the big battery on these. Definitely one of the favorite things about my computer.

i would purchase a 15" for this :D
 
The 7 hour battery does not exist plain and simple...I use my MPB close to the plug, but plug it in and out everytime the battery is charged...
 
dont worry. apple will simply find a way. they will not go lower than 7 hours on the base model (maybe less on the higher end ones, like they are now).

Yes, it does. The phrase "Your mileage may vary" comes to mind.

yep, if you turn your mbp on an just let it sit there, then yes, you'll get 7+ hours out of it...but use it for 7 hours? Come on. No one gets that, and it just makes people think they've got something wrong with theirs when people claim such.

Very true. 5 and a half is more realistic for light work (which is supposedly what Apple uses to test their maximum life). But you can run the battery down in as little as an hour if you tax the machine.
 
I had my 17" uMBP for about 5 months now and while using the 9400m gt card with 1 notch in brightness, I get around just under 7 hours of battery life (just browsing the website).

I love it, I dont have to bring a charger while I'm on campus all day.

Sure but mileage implies you're actually moving (as in with a car), if you do nothing then sure you get those 7 hours (and I even doubt that). I'd go for 4-5 hours tops in regular usage.
