For the first time ever, Apple s newest MacBook Pro has not received a buy recommendation from Consumer Reports due to inconsistent battery performance.The organization tested three MacBook Pro variants including the Touch Bar model and found that the battery results were highly inconsistent from one trial to the next. While Apple has expressed equal surprise over the results, the organization has stood by its findings and said there is no need to repeat the tests.

Following the findings, Apple VP Phil Schiller expressed surprise, saying the findings did not match the results from the company s own test lab results or field data. In its findings, the organization reported that in the three consecutive tests, the13-inch model with the Touch Bar ran for 16 hours in the first trial, 12.75 hours in the second, and just 3.75 hours in the third. The 13-inch model without the Touch Bar worked for 19.5 hours in one trial but only 4.5 hours in the next. And the numbers for the 15-inch laptop ranged from 18.5 down to 8 hours.

Working with CR to understand their battery tests. Results do not match our extensive lab tests or field data. https://t.co/IWtfsmBwpO

In a response to 9to5Mac, Consumer Reports director of electronics testing Maria Rerecich said, In this case, we don t believe re-running the tests are warranted for several reasons. First, as we point out in our original article, experiencing very high battery life on MacBooks is not unusual for us in fact we had a model in our comparative tests that got 19 hours. Second, we confirmed our brightness with three different meters, so we feel confident in our findings using this equipment. Finally, we monitor our tests very closely. There is an entry logged every minute, so we know from these entries that the app worked correctly.
Consumer Reports for testing the battery performance on the MacBook Pro downloaded a series of 10 web pages sequentially starting when the laptop battery is fully charged and ending when the laptop shuts down. The organization further explained that these battery tests were conducted using the MacBook Pro s default web browser- Safari. During the tests, the laptop screens were set to remain on and with display brightness set to 100 nits which is considered to be the typical level one might use it while indoors or outside.
The same tests were conducted using the Chrome browser. Interestingly, it has been always reported that macOS users find Chrome as a power hogging browser and draining battery faster than Safari. However, the Consumer Reports findings revealed that the battery life was consistently high on all six runs using Chrome. ALSO READ: MacBook Pro 2016 teardown reveals custom SSD, smaller battery
In light of the contradictory findings, Apple is reportedly working with the organization to try to find an explanation to the unusual report. Meanwhile, users have also been reporting erratic battery performances. In one instance, some users have reported a battery life of ranging from full 10 hours to five hours or less as claimed by Apple. However, none of the users reported statistics were as alarming as the Consumer Reports findings at as little as 3.75 hours.
