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.”
