Consumer Reports will be retesting the new MacBook Pro

A few weeks ago, Consumer Reports published a report concerning the erratic battery life of the latest MacBook Pro, which would sometimes last as long as 19.5 hours, or as little as 3.75 hours. It was because of this discrepancy that the long-standing publication decided not to give the MacBook Pro a 'Recommended' rating for the very first time.

Naturally, Consumer Reports’ decision did not sit well with Apple.

After spending time working with Consumer Reports over the holidays, Apple discovered that a software bug in Safari was the culprit behind the temperamental battery performance of its MacBook Pros, and have since issued a software fix through its Beta Software Program.

Here is Apple’s statement regarding its recent findings in full:

“We appreciate the opportunity to work with Consumer Reports over the holidays to understand their battery test results. 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. This is not a setting used by customers and does not reflect real-world usage. Their use of this developer setting also triggered an obscure and intermittent bug reloading icons which created inconsistent results in their lab. After we asked Consumer Reports to run the same test using normal user settings, they told us their MacBook Pro systems consistently delivered the expected battery life. We have also fixed the bug uncovered in this test. This is the best pro notebook we’ve ever made, we respect Consumer Reports and we’re glad they decided to revisit their findings on the MacBook Pro.”

Consumer Reports is currently in the midst of retesting the battery of the new MacBook Pro, and will update its report accordingly once they’re done.
