    Last month, the new MacBook Pro did not receive a purchase recommendation from Consumer Reports due to battery life issues that it encountered during testing. Apple subsequently said it was working with Consumer Reports to understand the results, which it noted do not match its "extensive lab tests or field data."

    Apple has since learned that Consumer Reports was using a "hidden Safari setting" which trigged an "obscure and intermittent bug reloading icons" that led to inconsistent battery life results. With "normal user settings" enabled, Consumer Reports said it "consistently" achieved expected battery life.

    Apple's full statement was shared with MacRumors:
    Apple said it has fixed the Safari bug in the latest macOS Sierra beta seeded to developers and public testers this week.


    Consumer Reports has issued its own statement on the matter to explain why it turns off Safari caching during its testing and other details:
    The non-profit organization also acknowledged user reports of poor battery life that have surfaced over the past three months.

    Consumer Reports said it will complete its retesting of MacBook Pro battery life and report back with its update and findings when finished.

    Apple advertises that the latest MacBook Pro models get up to 10 hours of battery life on a single charge when watching iTunes movies or browsing the web. This estimate can be affected by several factors, such as screen brightness, which applications are running, and other system processes.

    "This is the best pro notebook we've ever made..."

    Let me guess...Schiller crafted this line? Marketing spin 101.

    Well, it doesn't really speak for Consumer Reports that they didn't do additional testing. If it's a Safari setting, then an alternate battery life test with Chrome (very common use case) would've easily showed the anomaly in battery life. Why do they have so much credit anyway?

    Clearly not a Pro machine if you are required to use Safari to get best battery life.
    The older MBP laptops could use any browser, or amazingly it it could run Pro tools like Adobe products without killing the battery. Apple, if you say it has up to 10 hours for a Pro laptop, then we expect around 8 or 9, not 2 or 3. Safari is no excuse.

    EDIT: Could we stop ranting about how Chrome is better. I'm just trying to point out that Apple is no longer designing this laptop to have good power for Pro software like Adobe products. Chrome I would not consider a Pro product.

    It still doesn't fix the problem with the 2016 model having 1/3 smaller battery than the 2015 model.

    Definitely the best MacBook Pro I have owned. Not saying the last generations weren't good either, but these are great machines. Wonder when that Safari fix will make it to us.

    I don't think they said that at all. They said the results that CR saw shouldn't be usual based on the way they were running Safari, but they still said they found a bug that they have sense squashed.

    They can say that the testing setting they used wasn't common, be right and still admit that there was a bug that needed to be fixed without trying to pass the buck. Problem found, problem resolved.....I don't really see the need to jump up and down on anyone here.

    People seem to be mis-understanding the explanation when they say "they were testing it wrong" - it's clear from the explanation that they were simply using Safari wrong...

    so Safari kills battery life and Chrome kills battery life. Basically we shouldn't browse on our new Macs =/

    Trust me. It's not. I have had the shocking 2006 model. I've had the kernel panicking GPU ridden 2008 model. I also had the image retention, screen peeling, pixel blowing 2012 model. I loved them all, but this is a huge step up for me and the smoothest first gen MacBook Pro I have used.

    Although Apple fixed them all no questions asked (the 2012 one 4 times!), visits to the Genius Bar are hardly what I consider a Pro feature.

    Killer machine.

    But 3 hours battery life when using one music pro application, for the princely sum of £3.5k?

    Is it April fools ?

    This fix does nothing. The battery is too small. End of story.

    Love Apple but currently our relationship is taking a time out.

    No, not at all. It was tested in a manner not typically used by a user. Sure, one wants it to perform as it "should" even with developer settings adjusted, but at least this revealed a bug only seen under these circumstances so it can be retested and verified fixed, or not.

    It's a shame Consumer Reports targeted the battery in their 'not recommended' review instead of the glaringly obvious lack of ports, expandability and user repairability. Maybe then Apple would have got the message.

    I'm pretty sure even the old machines, there's a difference in battery life between Apple apps and 3rd party apps.

    I hope it is fixed!

    Even if it is, too many poor choices to recommend the 15".

    Possible I am understanding this wrong, but it sounds to me like BECAUSE they used safari (and because of a bug in safari), the battery drained faster.

    Surely we can't hold a company liable for battery claims when using third party software though. That's just silly. If I may make a crazy car analogy, this is like being upset that my MPG on my vehicle changed drastically after deciding to make alterations to said vehicle. The claims are always going to be stock configurations.

    Did you think for 5 seconds before you posted this?

    Of course this could have been avoided if CR reached out to Apple before rushing to publish. Something is clearly wrong when their test results had such wide variances.

    Can't wait to get mine with only one port type to worry about. I hope they do the same to the next iPhone/iPad and are consistent across all devices.

    Seems to me Apple resolved the problem yet more whining.

    Um, CR actually got worse battery life when using Safari.
