Apple's latest MacBook Pro series may have launched last fall, but the Consumer Reports' labs results have just recently gone public. This particular series has already made Apple history as the first MacBook Pro laptops that have failed to achieve a recommended Consumer Reports rating.

The new MacBook Pro laptops did well in display and performance tests, reports Newsy, but they failed due to some pretty severe battery life issues. The latest models' battery life was slated to last up to 10 years between charges. Consumer Reports tested three MacBook Pro laptops and found the battery life difference between models staggering. One model lasted as low as four hours while another made it all the way to 19.

The company tested Apple's 13" MacBook Pro with Touch Bar, the 13" MacBook Pro without Touch Bar, and the 15" model with Touch Bar. Despite rigid controls, the figures remained "widely disparate," according to CNBC. For instance, the 13" model with Touch Bar ran for 16 hours between charges in the first, 12.75 hours in the second, and a mere 3.75 hours in the third. The 13" without the Touch Bar ran 19.5 hours, and then 4.5 hours.

Jerry Beilinson, a reviewer at Consumer Reports, stated that the acceptable margin of difference for battery life is 5% or less. In other words, an hour or so difference is already slightly pushing it. Given that battery life is an important attribute for any laptop (as the laptop's portability and usability hugely depend on it), it represents a significant portion of the Consumer Reports score.

"After factoring together our complete test results," Beilinson said, "Consumer Reports finds that all three MacBook Pro laptops fail to meet our standards for recommended models."

What's interesting to note is that Apple recently removed battery life estimations in macOS. The Consumer Reports data was shared with the company, but so far Apple has yet to release a statement on the issue.
