Apple makes fixes to MacBook Pro after Consumer Reports’ findings of poor battery life

Apple has issued a software fix to address the poor battery life in its MacBook Pros, the issue that kept Consumer Reports from recommending the laptop for the first time.

The product-review magazine in December confirmed what MacBook Pro owners had been complaining about since November, when new versions of the laptop became available. Consumer Reports said tests on three different models showed inconsistent battery life. As we reported then, some¬†customers had complained about batteries running down in as little as three hours instead of Apple’s promised 10 hours.

Apple told Consumer Reports, which has written about the fix, that the magazine’s tests triggered a bug in Safari.

“We learned that when testing battery life on Mac notebooks, Consumer Reports uses a hidden Safari setting for developing web sites which turns off the browser cache…. We have also fixed the bug uncovered in this test,” Apple told the magazine, adding that “this is not a setting used by customers and does not reflect real-world usage.”

Phil Schiller, Apple’s senior vice president for worldwide marketing, tweeted in December that Consumer Reports’ “results do not match our extensive lab tests or field data.”

The magazine says it is now doing some retesting of the MacBook Pro and will be reporting its findings at a later date. It explains that its tests of laptops by different manufacturers are done in a comparable way, and that “we look to control as many variables as possible.”

    So CR dioes a test wherein they meddle with the software settings, so they are really not testing the product one buys. They are testing a hacked (in a way) product. The product is a compbination of software and hardware, not one or the other. So once again CR proves they do not know what they are doing when they design the tests for the latest technologies. This was not an Apple bug, it was a CR screw up that Apple has now presummably disabled. Beware of fools reporting test results.

      Was it also the problem for the hundreds who experienced the same issues with their shiny new Macs
