The 13-inch Retina MacBook Pro beat 18 Windows 8 laptops in a battery-life test conducted by Which? (http://blogs.which.co.uk/technology/computing/laptops-computing/windows-8-laptop-battery-life-how-does-it-measure-up/), the UK consumer test organization with a reputation for the most detailed testing in the industry.

http://images.macrumors.com/article-new/2013/03/which.png
In the web-browsing test where most laptops performed best, the Acer Aspire M5-581T was the longest-lasting Windows 8 machine at 358 minutes, while the 13-inch Retina MacBook Pro lasted 30 minutes longer. The Which? test was primarily aimed at comparing Windows 8 machines, but they included two non-Windows machines as a contrast. The MacBook Pro topped the list, while a Samsung Series 3 Chromebook came out in the middle of the pack at 224 minutes.The longest running Windows 8 laptop for web browsing is the Acer Aspire timeline Ultra M5-581T - a 15.6? screen, 2.1kg ultrabook. It lasted almost six hours on battery - enough to get you to from London to Middlesbrough and back - and fell 30 minutes shy of the battery life of the 13? Apple Macbook Pro Retina, but costs around 500 less.

If you switch to watching movies from the Acer's hard disk, you'd get four hours and 37 minutes of movie viewing time - a little over an hour less than the Macbook.Similar to Consumer Reports in the United States, Which? is known for scientific approach and detail (http://www.which.co.uk/technology/computing/guides/how-we-test-laptops/) in its testing. For example, product testers hook up laptops to lab gear to measure power consumption, use thermal imaging systems to measure heat and use light-measurement kits to test screen brightness.

I'd like to know if these were clean installs of Windows.

Windows can be very light when installed. Many of these OEMs load SO MUCH CRAP onto the systems, though. Trial AV may load on start (even if Win8 already has it built-in), some silly 3rd-party toolbar or dock may load on start. Maybe something like the Bing Desktop or Ask Tool bar or whatever loads on start.

"New" Windows computers sometimes ship with around 80 things in the Add/Remove Programs screen.

Probably tested as received, which is how it should be. 90% of people are just going to run windows with all the crapware on it because that's how it's set up when they buy it, so testing it in a theoretical setup that only a small percentage of people will use is a pointless test.

----------

Bad argument as the 15" screen gives more room for battery. It's been said that the latest chromebook has an unusual aspect ratio and rather large screen bezels for no reason other than to lessen the design constraints and to give them 100 lines of horizontal resolution so they can call it the "HIGEST RESOLUTION LAPTOP DISPLAY EVAR!!!!!111!11!". Oh, and we can't forget that the MBP is running a display with 4x the pixels, and a processor that's 50% faster.

I agree. It would even out the playing field and strictly compare the hardware of all the machines.

If they wanted to compare the software, then they need to get identical machines (say, multiple rMBPs with the same specs) and have one run OS X and the other run Windows 8.

As is, this "scientific" test is a bit... lacking in its scientific rigidity.

Terrible argument. The battery life savings of SSD vs. HDD wouldn't yield this big of a difference and screen size has absolutely nothing to do with battery life but resolution does. An ultra high resolution 13" screen should be less power efficient than a 1080p 15" display.

To be fair, they should have compared it to the 15in rMBP then.

My 2010 MacBook Pro gets *pathetic* battery life if the GeForce card kicks in - which is ALL THE TIME.

I tried using gfxCardStatus to disable it, but it just causes some things to crash.

My battery has 91% life (6308 mAh of 6900 mAh), but I still only get around 2 Hours of battery on a full charge.

The answer is DO I CARE? What differences OEMS make? Or how they tear up Windiws on perfectly good hardware. Out-of-the-box the Mac comes ready to meet those lab benchmarks... THAT is what a customer cares about. That is why Windows is miserable dreck now.

Although I do like my super-locked-down Windows 7 install my company has.... Of course they only loaded half the hardware drivers so extra convienence buttons, trackpad scrolling, and the webcam don't work... But the machine is now a TANK. And it only has the ten programs they chose for me, ever so its hard to catch bugs.

A PC review place isn't going to go to that effort. It's been done by Mac fans. The results are always really bad for PC OEMS. In general Macs Running Windows with APPLE-MADE drivers still do slightly better than the PC guys across the board. It's still true when you carefully line up same clock speeds, ram, etc... Even if only a tiny bit sometimes.

That's just a little bit insulting when PC OEMS who's ONLY JOB is to run Windows get beat by Apple with the same hardware. PC reviewers don't keep sponsors very long pointing that out.

This! My 13" MBP (Early 2011) still has 89% capacity after 574 full cycles and routinely gets ~5 hrs on light browsing. Guess what HP's batteries have after 500 cycles - 5 min of battery life, a red "x", and "please replace battery".

Mar 11, 2013, 11:00 AM
Was Windows 8 also running on the MBP during the testing? I haven't read the Which? article, but I'm assuming they did run Win 8 on the MBP for testing purposes. If that's the case then kudos for Apple. My old HP laptop at work gets 3 hours max. running XP =P. It's one of those old models that still has a 3.5" disk drive as well as a DVD drive (not burner).

Yeah, I think I would do this too.

I've been shopping around for Windows 8 touchscreen laptop/tablet hybrids (like the Lenovo Yoga 13, Dell XPS 12, or even the Surface Pro). I'm still on the fence. One option I am keeping on the table is to buy a MacBook Air and install Windows on it as a dual-boot. I'd lose the touchscreen, though, which is a lot of the appeal of Windows 8.

I have a rMBP, and smudges on the screen annoy me, they still manage to get there without a touchscreen, I can't imagine how crazy I would go if I touched it on purpose. I am not sold on touchscreen on a laptop, but that's just me. I would not consider that a loss. I see the touch on windows 8 more as lipstick on a pig.

Maybe if you're lucky apple will update the macbook air to retina before you buy making your choice easier.

I have a 2007 17" MacBook Pro and a 2012 15" rMBP.

The 17" one is dead in about 2 hours.

It's not because OS 10.8 is better than 10.6, it's because of the chips and the screen and the rest of the hardware.

Apple probably chooses the most efficient components while PC OEMs are probably looking for a less expensive alternative which results in less efficient components.

All that would prove is that OS X and the device drivers are better optimised for Apple's hardware than Windows 8 and the bootcamp drivers.

I fail to see how we learn anything from that at all.

People will find anything to complain about but saying 95% of the battery problems on a MBP being software is nothing but conjecture, there's nothing to support that as a fact in any degree. My MBP's battery is clearly of a larger capacity than any PC laptop I own (even with an extended capacity battery) and the rMBP has an array of batteries strung up together in which no other laptop (to my knowledge), has.

You can clearly see the comments from other folks, already concluding that OS X had to be more efficient simply due to the limited data being presented. To be completely fair all operating systems have to be tested on the exact same piece of hardware to make such a statement.

The same could be same for the opposite scenario, would OS X fair decently on a non-Macbook PC (assuming all drivers amongst other things are available) designed to run on Windows 7 or 8? We won't know until it's actually done.

The closest I've seen as a fair test is on a Hackintosh which runs both OS X and Windows. In my experience I don't see any significant change in battery times using either OS, in fact it's close enough to be insignificant.

Maybe someone should compare systems from the very same price range with Apple's high-cost equipment and not systems that according to the article cost 500 British Pounds LESS than the Apple notebook?

Comparisons of battery lifetime are first and foremost SPECS comparisons; things that Apple users love to hate. So if you want to nail the difference on the software platform you can only do so by either comparing systems with the same hardware specifications -- OR -- by running both software platforms on the SAME computer. So how much difference is there between Windows 8 and OS X on that MacBook Pro? THAT would have been a comparison that actually means something. What we see here is just FUD.

Apple does a lot of optimisation in OS X for their own hardware which simply isn't done on Windows. In addition the Windows bootcamp drivers Apple supplies are rarely as well optimised as their OS X equivalents.

It would still come out in the favour of OS X and it would be even less fair.

I have the same exact laptop and have had no real problems with gfxCardStatus. However, I think you might not be getting all of the benefits from it because (at least for me) it seems to constantly switch back to "dynamic switching". I notice this most often with Google Chrome when I have to exit it for updates. Which version did you try?
