It’s official. With the release of the 17-inch MacBook Pro, Apple has completed battery life testing and published their specs for battery and power for their new pro portable Macs.
From Apple.com:
•15-inch MacBook Pro: 60-watt-hour lithium-polymer battery (with integrated charge indicator LEDs) providing up to 4.5 hours of battery life
•17-inch MacBook Pro: 68-watt-hour lithium-polymer battery (with integrated charge indicator LEDs) providing up to 5.5 hours of battery life
(Battery life depends on configuration and use.)
Complete 15- and 17-inch MacBook specs here.

I’m still trying to get 3 decent hours on my 1.5 12″ powerbook. somehow I don’t buy this specs –
MDN word;Trouble hmm.
Remember people, this is like a car’s top speed – it CAN last this long, but more often than not it won’t.
Not good enough.
We want more!
We wantit has longer life!
We want it cheap!
At least 10 hours!
Well, at this time we just have to accept the best…..
Bushit. My MBP 15 get 3.5 hours MAX under normal use, but interestingly a minimum of about 2.75 hours under heavy load.
I have a hard time believing 4.5 hours unless an hour is spent with the screen off and CPUs idle.
Of course these are maxes. Have to say that I did break 4 hours once, but typically see 3 hours plus or minus 15 minutes. Bluetooth and Airport appear to be real battery hogs on my MBP 2.16. Turning them off makes all the difference.
dumbass… if you want 10 hours, it is perfectly possible, but the computer will not be only 1″ thick… grow a brain.
come on idiots…
It’s like a mileage rating sticker on a new car… iyour mileage may vary…
Drive your laptop with the windows up, the A/C off, and you should average the ratings… Real world, of course, we all have the A/C on or the windows open…
it isn’t like any of the competitors laptops meet their ratings either… get over it morons!
I swear… MDN is like a lightbulb to moron bugs
Apple have always bullshitted. They’ve made an art form out of it. All manufacturers do it….
The G5 2.7 GHz vs Intel/AMD used to make me piss myself laughing. These benchmarks soon disappeared when the switch was announced. Anyone who had ever used a G5 and a loaded PC to do similar tasks new the real truth.
I have ordered a 17″ MBP even if the batteries last 3 hrs that’s plenty long enough for me.
MDN word “brown” as in two in the pink and one in the brown……
They aren’t too far off with their “best case” battery life ratings. I don’t run my MacBook Pro 15.4″ on battery very often, but when I do I can easily get 3h45m with wireless/bluetooth off and screen brightness at 50%.
Most Windows notebook battery ratings are almost double what can be achieved realistically…
Eric,
I wonder if you remember the accolades Apple received for announcing iPod battery life specs that the product actually beat.
In any case, nobody is a moron or an idiot for expecting a claim to reflect reality. Operating with a dimmed screen, not using airport of bluetooth, not playing a DVD, etc. are reasonable things to do to maximize battery life, but it appears even those things will not get the claimed results from Apple.
Also, 10 hours from Long Wait was no doubt in jest. Get a clue.
Turn it on
Dim the screen to one block
Turn off Airport and Bluetooth
Turn off Desktop Picture switching (faster than restart)
Energy Saver – Better Savings
Energy Saver – Spin Down HD
Quit all apps
Don’t touch or use the computer.
Watch clock…
I get pissed when my 12″ G4 doesn’t get at least 3.5 hours. Under normal battery mode i can do.
download a 700 meg file wirelessly, and burn that file 4 times.(this always get’s peoples attention)
or
general app use, (word processor, itunes, Safari) with wireless enabled I average 4 hours of continous use.
The biggest point though is screen brightness. Turning up screen brightness to 50% drops overall battery life by nearly an hour. So Unless i need it that bright I turn it all the way down.
nobody´s wondering about the weird difference in runtime between the two models?
the 17″ has a 13% larger battery (+ 8watt-hours) and therefore a 22% (plus 1 hour) longer runtime
although it has a higherclocked CPU, larger TFT, …
seems weird to me.
I find that the 15″ MacBook Pro gets up to 4 hours, but only with the screen dimmed most the way down and with minimal hard drive and/or cpu activity. 3 hours is more realistic.
4.5 hours would have to be with the screen brightness set to “1” and the hard drive idling the whole time.
I’ll bet if you did testing with the screen turned up to max brightness the 15″ would last longer.
DBS,
The specs are for the new Intel Macbook Pro and not your Powerbook.
list best-case numbers!
Every other laptop maker lists average-case numbers!
Oh, wait… no they don’t.
Apple lists best-case numbers, and CALLS them best-case numbers, because that’s how laptop battery life is ALWAYS stated.
Use your laptop one way and you’ll get the best case. Most likely you’ll use it in more demanding ways. That’s always been true for any laptop from any maker.
OK, every time these battery specs are posted, this same argument always come up.
Battery life specs are measured by the ABSOLUTE MAXIMUM battery life that the product can achieve. They take a new, completely unused battery, calibrate it, and let the computer sit idle and run down until the battery dies.
There is no way to calculate battery life under “normal” use. Normal use for one person could be simply browsing the web and using email, while normal use for a video editor.. you get the idea. C’mon, use your brains please.
why are you guys arguing about this ( kidding itws a good thing to argue about)
17″ + 4 extra bat. = one flight from London to Sydney
what else is new?
GET MORE RAM

My 17″ battery life has always been half what they say but thats kind of what I always expected anyhow, so Im not disappointed.
Same is true of ALL power devices.
I run all the save power procedures when possible but a lot of the time I HAVE to run it at max as Im processing images on location etc…..so I dream of a better battery.
I can get one DVD feature film per battery charge….but again….it is a 17″ screen.
Are there any 3rd party batteries?
I have seen the replacement Apple 17-inch MacBook Pro battery,
Battery Type :Li-ion
Voltage :10.80V
Capacity : 6200mAh
I think it is good.
