The problem that hounded MacBook Pro 2016 is far from over. The setback that started from complaints of the device's battery life has turned into an Achilles heel for MacBook Pro. This after the Consumer Reports gave a failing grade to the device, making it the first laptop in history that failed to get the recommendation of the organization.

The Consumer Reports pointed out on the mounting complaints against MacBook Pro after it failed to deliver the supposed 10-hour battery life that it vowed to provide during its market debut in October.

The organization noted that it conducted tests to three MacBook Pros, including the 13-inch model with Apple's new Touch Bar, the 13-inch model without the Touch Bar; and 15-inch model. All three devices failed the test after showing highly inconsistent results from one trial to another.

For example, it reported that the 13-inch with Touch Bar model ran for 16 hours in the first test, but it dropped to 12.75 hours in the second, and further dropped to 3.75 hours in the third test. The 13-inch without Touch Bar model worked for 19.5 hours in first test but dropped to only 4.5 hours in the second test. The 15-inch model ranged from 18.5 to 8 hours.

Battery life is an important attribute for a laptop, and it represents a significant portion of our overall score. After factoring together the complete test results, Consumer Reports said that all three MacBook Pro laptops fail to meet their standards for the recommendation.

Of the 140 laptops under the rating of Consumer Reports, MacBook Pro 2016 was the first to fail to get its nod. The Consumer Reports, however, pointed out that previous MacBook models scored well on battery tests lasting longer than what Apple usually claimed.

Earlier, a survey from among MacBook Pro users revealed that nearly 50 percent reported that that the device runs between four to five hours, while 25 percent said around six to seven hours. Around 15 percent reported eight to nine hours, and only 6.7 percent said they have full 10 hours.
