Apple's 2009 MacBook Pro: Battery Life to Die For

Final Words
There’s no other way to say this. If you care about battery life and portability at all, buy the new MacBook Pro. Go to the Apple store and buy one. While I only tested the 15” model, I’m guessing the 13” model should leave a similar lasting impression.
Ever since I first looked at the power consumption specs of Nehalem I thought it didn’t make any sense to buy a new, expensive notebook before Arrandale’s launch in Q4 2009/Q1 2010. While performance will definitely increase considerably with Arrandale, Apple just threw a huge wrench in my recommendation. The new MacBook Pro is near perfect today. If you need a new laptop now, thanks to its incredible battery life, I have no qualms recommending the new MBP.
The only thing you have to come to terms with is knowing that if the roadmaps still hold, that in 6 - 9 months there will be a much faster version of your notebook on the market; most likely at the same price. Combine the performance and power efficiency of Arrandale with the battery advancements in this new MacBook Pro and you’ll have one beast of a notebook.
Today I am more than comfortable saying that this is the best Apple notebook I’ve ever laid my hands on. The build quality is excellent, the base specs are solid and of course, the battery life. There’s no doubt that it could be better; toss in an SSD or drop the price even further, but as it stands the new MBP is an excellent choice if you’re looking for a Mac laptop.
Obviously, you can attain the same battery life with a cheaper notebook and one or two spare batteries. But there’s something to be said for increasing battery life by at least 50% without increasing the bulk or weight of the system.
I’m not sure there’s much else I can add other than Good Job, Apple.

Interesting. As I said my expertise on the mater is limited. It would be interesting to know what reasons there are for cylindrical cells.As I see it, they are more inefficient in both space usage and manufacturing. I'll see if I can find something on this.

Indeed, the older Macbook batteries contain flat rectangular cells, which was plain to see once opened. Therefore the comparison used by Apple currently, which leads you to believe that they used to be cylinderical, is wrong. They have been rectangular on Macbooks before, the material and size simply has changed, not the shape of the cells themselves.PlasmaBomb - Saturday, June 13, 2009 - link
My apologies, you are indeed correct... browsing my pics folder came up with the answer-http://pics.bbzzdd.com/users/PlasmaBomb/PowerBook....">http://pics.bbzzdd.com/users/PlasmaBomb/PowerBook....
Old powerbook = cylinders (NiMH I think).

Macbook = flat cells
(feel free to take a copy of the pics)
So they haven't used cylindrical cells for a long time, bad apple for deliberately misleading people :|
Sorry as I said I don't have a macbook to play with :(
The lithium ion battery from my laptop looked pretty much like this -

when I dismantled it (it was dead).

I have a Mid-2007 15" MacBook Pro (Santa Rosa 2.2 GHz) with 3 GB of RAM and a 500 GB hard drive (both upgraded by me from 2 GB - the extra 1 GB was free, otherwise I'd have 4 GB, and the 120 GB hard drive it came with was awful).Most of the time the battery life is just fine - but damn, this new 15" will DOUBLE what mine gets? Wow!
I think the new 15" MBP - in matte - with 4 or 8 GB RAM, a 512 GB SSD (or a 128 GB plus a hard drive, if there somehow was room: I need my iTunes library!), and maybe with the upcoming quad-core laptop CPUs would make just about the perfect computer.
Hopefully this is what the next generation MacBook Pro will look like and it'll be out about the time I start wishing my 2.2 GHz was faster.

Anand, I'm sure you've put in that X25-M. Let us know how much more battery life the notebook gets. Thanks!JarredWalton - Friday, June 12, 2009 - link
My understanding is that the X25 is a high performance part that doesn't dramatically improve battery life. However, it should be better http://www.anandtech.com/storage/showdoc.aspx?i=34...">by about 6%, give or take.PlasmaBomb - Friday, June 12, 2009 - link
Still 6% of 8 hours is a decent amount...about an extra half hour.

As a modeler of RC airplanes, I know that LiPO's require extreme caution, especially when charging. Search youtube for "LiPO Fire".Basically, if you charge the batteries too fast, they burn. Could the smaller brick have to do with battery charging rates?

I'm an RC pilot as well and IMO, the safety risks with LiPo packs have been greatly exaggerated in recent years. Most laptops and other portable consumer electronics devices these days already use Li-Ion or LiPo as is. All packs do have a serious risk of explosion and fire, but they usually don't spontaneously combust unless they're cheaply made and have internal faults. Remember that RC packs are rated for much higher performance than laptop packs. They're also subject to more stress in the form of vibration and hard impacts. In 99.9% of cases, they're safe in consumer electronics provided they aren't abused.The batteries used for laptops have built in charge circuitry and balancers.

That is what the chip in the battery and charging controller are for.
