Apple: Consumer Report's inconsistent MacBook Pro battery life caused by Safari bug

Apple officially announced that it was a Safari bug that caused the inconsistent MacBook Pro battery life test results by Consumer Reports. The Cupertino-based tech giant will roll out a patch to address the problems.

Consumer Reports did not recommend the MacBook Pro after they found out that it had varying battery lives. Besides their own report, there have been several users reporting inconsistent battery duration which is still not addressed by Apple.

Apple is not pulling their marketing claims regarding the MacBook pro battery life as the Consumer Report tests had a flaw due to the Safari bug, The Verge has learned. The Safari bug in question was a feature in developer mode that turned off the browser cache which led to the battery drain.

In addition, Apple claims that not everyone who owns a MacBook Pro will use the feature. Still, they will be fixing the bug with a patch that will be rolled out soon.

"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," said Apple in a statement set to Tech Crunch.

Consumer Reports will be re-running their tests for the MacBook Pro in order to reach a new conclusion regarding their recommendations. Other users are still skeptical regarding the update as their MacBook Pros still have inconsistent battery lives even if they do not use the Safari developer mode setting.

Apple did not comment on the other issues with the battery life. They also did not disclose when they will be rolling out the Safari patch. MacBook Pro users should be wary of what apps and programs they use as to not drain the battery faster than intended.
