MacBook Pro Battery Life
As regular readers will know, I own two notebooks, an original 1GHz 17″ Powerbook and a top of the Sony Vaio Z1. As we all know, the 1GHz 17″ Powerbook is based around a G4.
The PowerBook gets about 2-3 hours of battery life out of my typical use. That’s with the screen turned down to an acceptable level, now DVD drive use and most of the other power saving features switched on. I’ve had better than before now, but only when I’ve gone really offline and only the machine for writing or browsing content, rather than my more usual process of browsing the Internet (which implies wireless connectivity, and more power) and recompiling lots of code.
That’s why I specified the battery time in terms of my, so as not to confuse those readers who will chime in with comments that all timings are wrong…
The Sony Z1 is based around the Centrino set and the Pentium-M mobile CPU, both these components are predecessors to the components built into the new MacBook Pro. This has far more complex power saving systems, such as the ability to switch off (rather than simply not use) the DVD drive, and even to power off the PC Cards, built-in memory stick reader and of course reduce the CPU MHz and power requirements to a very low level.
With the standard battery on the Sony I get about the same period of battery powered usage as the Powerbook. It can be as high as 4 hours, but in the majority of cases a more realistic figure is about 3 hours of my more typical use.
I can slap in a larger battery (exactly twice the size and capacity) and that I can get about 6.5 hours mobile use. It does however ruin the look of the laptop, and raise the back by about 3/4 of an inch.
Now just to summarize:
Powerbook G4, 17″, standard battery: 2-3 hours
Sony Vaio Z1, standard battery: 2-3 hours
To get 2-3 hours (and more) out of a Powerbook is quite an achievement when you think about the Z1, which is Centrino/Pentium-M based and has a heap of power saving technology. Both are using the battery that came with the machine.
Standard battery, standard machines, more or less equal battery life.
Just in case the point I’m making still isn’t clear, using the Vaio, a notebook using the previous version of ‘low power’ technology that is in the new MacBooks I get the SAME battery life as my G4.
What could I expect out of the new MacBook Pro?
I’d expect about the same as I get from the Vaio, perhaps a modest 10-15% increase based on the newer technology, but that has to be tempered by a combination of other factors, like the fact that this is a first generation item from Apple, and that we’re using newer Dual-Core CPU.
For some reason however we have a bunch of Apple commentators (I refuse to call them fans, since they seem to be doing nothing more than slagging Apple off at the moment) who seem to think that the new PowerBooks should have 5, 6 or 7 hour battery life.
Why?
Hell knows – existing PC laptops get – as my Vaio experience demonstrates, about 2-3, 4 hours tops.
Why would an Apple-built, Intel based laptop somehow defy the laws of physics, common sense and exceed the capabilities of PC laptops that have been made by manufacturers using the technology for years before Apple got to it, somehow exceed by a factor 75% or more the battery life of existing Intel based laptops?
There’s a finite amount of power you can squeeze into a battery, and there’s a limit to how much you can reduce the power requirements of a laptop.
From a first generation – and more importantly, at the moment, pre-production Apple Intel notebook I think a time of 4 hours is pretty good. That actually equals, or beats, my Vaio.
While I’d love to see Apple produce a laptop that has a longer battery life, we need to be realistic. It’s going to take Apple a while to get the best out of the hardware, and even if they do improve the battery life, they wont be the first to do so – other PC notebook manufacturers will probably get there first. Apple were one of the first 10 companies to announce a dualcore Yonah laptop, so we’re already at the bleeding edge.
Meanwhile, give Apple a break – they enough on their plate right now without people criticising them for matching or beating the battery life of their old laptops and their current competitors.

Your article about battery life is disingenuous and comes across as a distraction from the crux of the matter.
I think the main complaint is Apple putting an expensive notebook machine on the market and selling it to customers without providing the customers with any battery life information.
The main complaint is not 240min vs. 180min vs. 120min. There are no published battery life figures, so no official comparison can be made by the customer.
Not publishing battery life information for the MBP is shameful on Apple’s part (or at least pathetic) and just another class action lawsuit waiting to happen.
From what I read on another site, a fully charged MBP has a battery life of just about 3 hours with standard power saving features enabled. Whatever the numbers are, Apple should have included this information, perhaps with a caveat that the numbers may change between now and the ship date. Would that be too much to ask if I’m plunking down $2K – $3K for a notebook computer? I think not.
Angry Apple Fan on October 28th, 2009 at 3:08 am
Agree. Apple really misleads the customers. On its website, it claims to be 7 hours long. I upgraded to MacBook Pro for this reason . Its battery not too impressive, only 3 to 3.5 hours long.
Martin MC Brown on January 16th, 2006 at 8:22 am
That doesn’t match the commentary and examples given digg, the story it links to at MacDevCenter or at Ars Technica where the criticism is aimed solely at the battery life duration, as 3-4 hours is a bad thing.
The fact that Apple hasn’t confirmed or denied any figures on a laptop that officially is not available yet (although you can order it) on a machine that is not even a week old is meaningless. Many companies (Apple included) announce machines and part specs long before they become available.
Apple don’t exactly have a brilliant track record on releasing all specs on their hardware – why should this case be any different?
Yet, for some reason, we have people panning Apple about capabilities of a machine that isn’t even available yet, as if the specs and capabilities are already set in stone.
Apple isn’t forcing you to buy the laptop right now, without seeing it – if you want to wait until the machine is released and some real figures start coming out, that is your choice.
The Architect on January 16th, 2006 at 8:45 am
I think the simple point is still that people would like to know what they are buying. Battery life is an important aspect of a notebook computer. And the MacBook Pro is not merely “announced”, it is FOR SALE.
Pushing all the responsibility for the quality of a product vs. making the vendor responsible is wrong. The courts of shown that time and time again. Maybe for the company it is cheaper to pay the settlements, but it builds ill will that over time comes back to haunt…
You’re right about the poor record that Apple has regarding machine specifications. Now that Apple is on Intel hardware, that record will have to improve.
Apple would only help themselves if they understood that all their games regarding specifications (well, the lack thereof) only end up hurting the company. If Apple wants to grow the company, they have to begin acting like a grown up company.
Martin MC Brown on January 16th, 2006 at 9:00 am
Yes, it is for sale, but if you ordered it today, you wouldn’t get it for months.
Why, quite frankly, would you even consider ordering a notebook weeks or months before you get it when the only reports and information you have available are show reports and, if you were lucky enough, a brief view at the show itself?
I don’t buy a car without test driving it, and yet I know that there are people who will put tens of thousands of pounds down before any specs on a car are released, just because they want to be at the bleeding edge. OFten they’ll do so months or even years before the car is actually physically available to drive.
Putting money down on an Apple laptop in the same situation right now would put you at the bleeding edge, but if you are that vain then you are not buying the laptop for it’s specs and functionality anyway. You are buying it because you want everybody else to know that you have the latest laptop.
If battery life is important to you, then you would wait for the specs and real details to be made available.
As for Apple growing up, it is doing nothing more than other companies have been doing for years. Some companies don’t even quote battery life at all.
I still think criticizing Apple at such an early stage for what is a completely new environment for them based on hardware which isn’t AVAILABLE, no matter that it is for sale, is an insult to what Apple *has* achieved.
Andrew Creek on January 16th, 2006 at 11:05 am
The release of the Macbook seemed to me somwhat empty. It felt as thought Apple expects me to buy it for two reasons. 1) Its a new Apple product. 2) Its got Intel inside. For anyone with a brain thats not a very good reason to purchase anything.
Tom M on January 16th, 2006 at 12:20 pm
Newsweek has an interview with Jobs, where he states that MBPro battery life will be the same/comparable as present models. (Note: gotta come up with a better acronym. Maybe a better name to begin with?)
Bottom line: don’t be an early adopter, unless you have a high tolerance for disappointments, or even bugs. Also, please don’t assume that Apple is only producing models to meet YOUR (and only your) personal requirements. When you realize that Apple targets their products at the largest market segment so as to maximize their sales and profits, then you won’t be so mortally offended. It’s a laptop and you can still buy the Powerbook.
Daniel Ortego on January 16th, 2006 at 1:08 pm
Laptop or notebook equals compromise. There has never been a laptop computer that would satisfy my expectations. Having said that I will say that I’ve already ordered the MacBook Pro but now I may cancel the darn thing because I don’t want to wait just to get another under powered Mac. The iMac 2.0 appears to be the better bet.
Doc Swift on January 16th, 2006 at 1:53 pm
I am currently on a nearly 4 year old powerbook- I have been ready to upgrade for six months now but was waiting for the intel update before ordering cause I find the current G4 pb less than compelling. Personally, I am excited for my macbook pro to show up- because while I prefer my dual G5 for my heavy lifting, I spend 75% of my time on my pb on the internet, ichat, email, etc. I think this is a smart move by apple cause it is putting the first generation equipment into the more technically sophisticated users (as opposed to the ibook mob).
nikster on January 16th, 2006 at 4:46 pm
Consider this possibility: Apple may simply not know the battery life yet. Intel has announced LV versions of its 1.66 and 1.83 GHz Core Duo processors, exactly the ones used in the Powerbook. They are supposed to ship in February.
LV stands for low voltage – the LV versions are supposed to use much less battery than the standard versions. But the timing of the LV introduction would make this pretty tough to meet.
Anyway, it would explain two things: 1) That there’s no mention of the battery life and 2) That Apple uses 1.66 and 1.83 chips but no 2.0 GHz versions – LV versions are available only for 1.66 and 1.83.
Worst case Intel can’t deliver the LV chips in time and Apple slaps in standard (non-LV) version which would reduce battery life but presumably still work well enough.
Ralph on January 16th, 2006 at 9:50 pm
Interesting way of saying that 2-3 hours of battery life is acceptable. No, it’s pathetic!
The Powermac G3 (Pismo, built 2000) with a G4 550 upgrade runs Tiger and all modern programs with acceptable performance, and runs OS9 just fine. It has Firewire 400, USB, a PC card slot, VGA out, and airport. It can burn DVD’s and has a bright 14″ screen.
It also has an 11 hour battery life if you put batteries in both its slots. It blows the doors off the Macbook in that department. And, you can get one, loaded, for $600.
Battery life is more critical to me than speed of gaussian blurs. It looks like I’ll be sticking with Pismos for a while yet.
KenC on January 17th, 2006 at 12:07 am
Haven’t seen any articles suggesting that the new MacBooks will get 5, 6 or 7hrs of life.
However, I’d agree with you, that I expect the new MB to get about the same to 10% better battery life than the PBs. I’ve posted at other sites that I base it on Steve’s slides where he points out that the new chips are 4x more power efficent. And, that the chips are 4 to 5x faster. Thus, dividing the power/watt ratio by the power fig, you get about the same, or a little more power hungry. Of course, the battery is 20% larger, so, I figure about the same, or slightly longer battery life.
Martin MC Brown on January 17th, 2006 at 2:48 am
Ralph: You are not comparing the same speed or specification of laptop – and you are using two batteries, instead of just one. If I used two batteries on my Vaio I could 12 hours or more, but that’s not the point.
You are in fact doing exactly what I repeatedly point out, both in the original and my replies – you have decided that battery life, rather than the spped and capability of the machine, are more important to you. If you are happy using Pismos, please feel free to continue :))
DannyW on January 17th, 2006 at 4:39 pm
2-3 hours would be good for me. I have recently gotten rid of a top of the range vaio, with webcam, 17inch screen, 2GHz processor etc. The battery lasted approx 30 minutes, without using the DVD.
racer5 on January 17th, 2006 at 8:43 pm
Okay, I was ticked offf at Apple too for not posting the figures BUT at MacWorl I quickly discovered why.
The Pre-production samples at Mac world had still MAJOR issues with the Power Management. I mean major. With an Apple Rep (Or do we call the Mac Reps now??) standing next to me I closed the MacBook. She instantly said “Doh, gonna need a reboot. The PM is not completely functional as of yet”. Sure enough a forced restart was required.
So the reason no figures are claimed is that it flat out is not fully functional. Can’t do real world tests until you have that nailed down.
In Febuary we WILL know.
Keeem on January 18th, 2006 at 12:41 pm
I have a recent middle-of-the-road Dell laptop and it gets a whopping 5 hours! That’s without any CD/DVD use and with wireless turned on (and other ports disabled) and it’s 15″ hi-res screen. I can even use my usb mouse and it doesn’t noticably impact battery life on this puppy! Now, my 17″ G4 Powerbook gets, if I’m lucky, 2 hours.
David on January 23rd, 2006 at 8:34 am
For me the most important factor in “going Pro” is the battery life. I currently get 3 hrs on my 1.25GHz G4 15″ PB (which is still a great machine), and would only “go Pro” if there was an improvement. It is probably unrealistic to expect a substantial improvement in the Pro 15″, however, unless Apple finds room for a bigger battery. With all that said, your 17″ PB gets the same battery life as your 14.1″ Sony Z1, yet the 17″ has a much bigger display. We forget that the display draws the most power of all. Given that Apple said that the new Pro displays are brighter, I expect that it may only be the 17″ and 12″ Pro (when they come out) that will offer better battery life.
Steven on January 23rd, 2006 at 2:56 pm
I ordered a MacBook Pro few hours after the Keynote without knowing how many hours i will get out of its battery ’cause I’m sure Apple will do the best possible. So no douts here.
Otto on January 26th, 2006 at 10:27 am
When it is more than 4h it is okay for me. I use my pb12″(new) for 5h but, thought the macbookpro has an 15″ screen 4h will be a good time. Hopefully it will!
Otto on January 30th, 2006 at 2:08 pm
my pb has 5h of battery life, a bit more for an 15″!
New = more ,I think!
Calista on February 22nd, 2006 at 7:02 am
Why not just buy a second battery, they are inexpensive ($50 for a third party version) and will dubble the available time. Many can instead skip the weight (and hassle) of carrying the power adapter for daily use.
And yes, if you throw $2500 on a laptop another $50 to make it a bit more portable shouldn’t be a problem.
Philip Beni on March 1st, 2006 at 4:47 pm
Wow recently I picked up a mac book pro from the apple store(first shipment). I thought the same thing; however, it gets better battery life than I ever dreamed possible! I am a student in high school, and about a month ago I purchased a powerbook g4 15″(1.67ghz). The battery lasted about four of the six hours i needed it for. So, I returned it and waited for the macbook pro to arrive. When I got it, I charged it up and installed all of my gadgets, keep in mind this was two days ago. I had the screen reasonably bright(half way) and did my school thing, and at lunch I played Doom for a half hour. I was also connected to the wireless network for 1/2 the time. At the end of the 6hr day of school, I still had about 45 minutes left. The battery life on it when using all of the power saving features, I imagine, would be around 8 hrs. This is probably due to the new architecture, cooling system, and the new lithium polymer battery.
Mark on March 12th, 2006 at 11:31 am
Philip Beni, please – you’re claiming 8 hours outa the thing, what taking notes, surfing the web or what ? Or did you actually leave the mac book in your bag during lessons sleeping ? I don’t believe you got a full school day, with some gaming of the mac book pro, unless you actually left it inyour bag for every lesson and nly had it out at lunch ?
Angry Apple Fan on October 28th, 2009 at 3:15 am
This is not possible. Even Wall Street’s Mossberg suggested in a MacBook Pro review that the battery does not live up to its 7 hours promise. It barely reaches 4 hours, even shut down most of the windows and dim the light. 8 Hours, you must be using it with a Cord when you go to school.
Scott on April 1st, 2006 at 3:47 am
I only get 3-3:30 hours when my macbook pro is 100% (according to the Time Remaining indicator). Is this normal or do I have a dodgy battery. Ive only had it 2 weeks.
Ron on April 3rd, 2006 at 4:56 pm
I just got my MacBook and get a little over 2 hours with the battery. I’m a bit disappointed in that fact. Other than that, the machine is great. Another battery will be a small price to pay.

Mr B on June 21st, 2006 at 9:33 pm
Had my MacBook Pro less than a day, have it setup next to me at work to see how the battery life fairs. I must say that it has confused me on several occasions so far as one minute it reckons it has 4-5 hours left, then it recalculates and goes back down to more like 2.5 hours…bizzarre.
jeroen on June 24th, 2006 at 1:23 am
i have used my new mbp with airport on, max 2,5 hours and only internetting… all people here defending this work probably for apple.. its stupid and the last time i ever buy ridiculous expensive apple stuff.. its getting only about beauty and not about the inside quality anymore ..
and for mister philip beny, u work for apple right>?

Pingu on July 18th, 2006 at 9:58 am
I own a white MacBook, and i read that the maximun battery time is 6 hours on this machine.
6 hours??? How the hell did they manage to get 6 hours out of it?
When mine is fully charged, i can get maybe 2 hours with wireless internet with bluetooth turned off!
I think it´s a joke, but whatever!
.
I would like 3-4 hours even with bluetooth on, but i guess that is not possible.
How about some pirate batteries or more powerful ones?
This and the heat, really drags the machine down as a portable one.
I do love it, but it sure loses points.

I have a MacBook Pro – got it about a month ago. When I first bought it, the battery was lasting close to four hours. Considering I was lucky to get 90 minutes out of my old laptop battery, this was a dream come true! In the last month though, the performance has started to decrease and today – only three hours. I’m only running an internet browser and iTunes – and occasionally a couple other apps, but nothing that would grind anything to a halt. I’m hoping this isn’t the beginning of the end – or that I’ll need to just suck it up and buy another power cord.
Dave on November 23rd, 2006 at 5:53 pm
I have an Intel MacBook Pro, 15″ 2.33GHz, Core 2 Duo. After a full charge, I will usually get about 3.5 to 4 hours of battery life, assuming normal operation.
But of course the more your computer does, the more energy it takes and there are many ways to adjust your laptop’s performance to get more life out of the battery. For example, turning the display brightness almost all the way down can give you about an extra 30 minutes. Or you can get an extra minutes switching the display from black on while to white on black (this is a feature in the Universal Access System Preferences). If you don’t need Airport, turn it off; that saves still more energy. Turn the speakers off, turn the keyboard backlighting off, etc.
Kerry on January 11th, 2007 at 7:41 pm
I’m barely getting an hour out of brand new MacBook Pro, 15″ 2.33GHz, /core 2 Duo. I’m wondering if it is in fact defective? I think I will go back to the store and demand a new one.

i have a brand new macbook pro bought may 2007, the battery has never lasted more than 2 hours and at one point, when i was running everything and heavy graphics, the battery only lasted 30 min!!!. we realy should get at least 3 hours no matter what!!! ive been using macs now for 10 years and i must admit i do not like the way they look and feel now they are pentium.

Just traded in my 4 year old G4 titanium powerbook for the new MacBookPro 15.4in 2.2 Intel 2. After one week of use, I can say with confidence that my old computer had better battery life! Just running airport, safari, word, and mail so I can work in the living room, I’m getting only about 2.75-3 hours of battery life. This is a big disappointment since I expected an improvement over the old machine, and I agree with the other posts that it’s unfortunate that apple doesn’t display this info in the specs – might have thought twice about it!
Susanna on July 23rd, 2007 at 2:52 am
I just have a quick question about my battery, since I’m not sure whether I’ve accidentally ruined it or not. The thing is, my Macbook Pro just shuts down when the battery gets to a certain point. Like the first time it happened, it was around 20%, but the second time was when it was around 40%. My question is, is it time for me to get a new battery or is the problem something deeper? Thank you so much in advance.
Sebastien on August 21st, 2007 at 3:40 pm
hi,
i have a macbook pro 1.83GhZ, 1.5 Gig Ram
ans i have to say that the battery is a big problem.
I did this Battery Exchange Programm, so I have the good one in my macbook pro. But now after six month i can´t use my computer more than an hour without the power supply. I don´t know if my computer has a specific problem but it´s not a Laptop anymore it´s a desktop and a expensive one (i payd for it 3000 dollars). I had a G4 Ibook for 2 years and he was able to make 4 hours without problems. I love Macs but sorry the MacBook Pro is a joke!!! Kind Regards
Anders on November 25th, 2007 at 9:09 pm
The reason that people have hostility towards Apple on this point is because while Apple makes superb machines, they have a notorious record of being incredibly obtuse when it comes to disk space and battery time. It took them years to realize that one needs more than a minimal pittance of a hard drive on their machines, and if I’m buying a “pro” machine, I expect “pro” performance, especially when it comes to the battery time on a laptop. I’ve never managed to get more than 1.5 hours out of any Apple laptop, and I’ve owned them since 1993.
Will I buy another one? Yes. But not without grilling the hell out of the salesperson on this question of battery life.

My request for new MacBook Pro batery was rejected by Apple today. Battery 22 months old, lasts 12-20mins before stopping without warning. Holds 1692mAh after 297 cycles (so much for 80% of original charge after 300 cycles!). Extremely poor considering my friend with 4 year old clapped out Dell still gets over an hour from his battery
Apple said battery is a consumable item and worn out, not covered by their 2year extended warranty on Sony batteries, despite fitting their criteria of a faulty battery. It was purchased 27 March 2007, in the timeframe of the recall.
I have spent over $10,000 on Apple products in last 5yrs including imac 24″,imac 17″, MacbookPro 15″, and 2 mac mini’s, not to mention Airport expresses and extremes, and software upgrades.
Extremely angry at Apple stance, poor handling of issue despite fitting all criteria on their service website. All goodwill destroyed, I won’t ever sing their praise again, all for the cost of a minor part. Right now, they do suck!
Angry Apple Fan on October 28th, 2009 at 3:19 am
7 Hours is Misleading Battery Life for MacBook Pro. They exaggerate and over-claim its battery performance
