Earlier this week Consumer Reports said that they ‘do not recommend’ the latest MacBook Pro. This is the first notebook the firm couldn’t recommend due to inconsistent battery life during their test.
Now, Apple marketing head Phil Schiller says that the company is working with Consumer Reports to “understand” the tests.
Working with CR to understand their battery tests. Results do not match our extensive lab tests or field data
This is a bit strange, however. While Consumer Reports’ test results did yield some 3.5 hours of battery life, which is totally plausible under load, the firm was also able to get 18-19 hours of battery life in other tests. Which, as we all know, is more than Apple’s claimed 10 hours of battery life.
If anything, these tests are in Apple’s favor. Consumer Reports says that it’s normal to see battery life vary within 5 percent between tests, however the MacBook Pro battery life performance is something strange.
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.
In the meantime, Apple has removed the battery remaining indicator in macOS 10.12.2 because the company deemed it inaccurate.
