Inconsistent battery life in new MacBook Pro comes from a bug relating to Safari


Consumer Reports initially tested the new MacBook Pro and slammed the new Apple product for poor battery performance. Now Apple has proved to Consumer Reports that the poor results are a result of a software bug.

Critical Reports tested three MacBook Pros, with one having a paltry battery life of 3.75 hours. This lines up with complaints about the MacBook Pro with Touch Bar having terrible battery life, even under light loads.

Consumer Reports revealed that its initial test was flawed, as they switched off the Safari browser cache for testing. This switch led to a bug that drains the battery. Now Consumer Report will be retesting the devices to see what changes.

“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,” an Apple spokesperson said.

What about those complaints from people who bought it? They had pretty dismal battery life in more real-world situations.
