Apple’s recently revamped MacBook Pro notebooks with the Touch Bar have received a few mixed reviews. Now the well-respected product testing organization Consumer Reports has said it cannot recommend the new notebooks, due to what it said was inconsistent results when it tested its batteries.
According to iMore, the group conducts its tests by having the battery fully charged on the notebook. It then downloads 10 web pages, which are then stored on a local server and transmitted on a local Wi-Fi network. The tests go on until the battery runs down. The official tests use Apple’s default web browser Safari.
Consumer Reports posted the final results of its research:
In a series of three consecutive tests, the 13-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.
Obviously, those numbers show a huge amount of differences for battery life on the new MacBook Pro models. Consumer Reports does say that it conducted unofficial tests using the Chrome browser and found that the battery life was consistently high on all those tests. However, since their official tests with Safari showed inconsistent results, that was enough for the group to not recommend the MacBook Pro.
Late last week, Apple’s head of worldwide marketing Phil Schiller posted on Twitter that the company would be working in some capacity with Consumer Reports to fully understand their battery testing methods. It will be interesting to see if the group sticks with its methods or makes some changes.
