Apparently, Apple can’t understand why the site gave it such a terrible score when most of the tech press praised the out-of-date overpriced laptop to the skies. What sank the MacBook Pro was a terrible score on battery tests.

Apple has difficulty trying to work out why Consumer Reports test data is so different from the marketing material it supplied.

Consumer Reports published a report last week saying it could not recommend any new MacBook Pro model due to its erratic, if not bad battery life.

"The MacBook Pro battery life results were highly inconsistent from one trial to the next," Consumer Reports said.

Apple Senior Vice President Phil Schiller followed up with a tweet late Friday saying Apple is "working with CR to understand their battery tests. Results do not match our extensive lab tests or field data".

He then got particularly nasty claiming that Consumer Reports made up its results because it wanted a pre-Christmas headline. He said that the magazine should have done more testing until it matched Apple’s marketing material or just cut and paste that marketing material into its review. We guess that is what the New York Times did.

Consumer Reports' review says that in-house testing revealed wild fluctuations in battery life for unplugged MacBook Pro computers. In the case of the 13-inch model without a Touch Bar, for example, battery life ranged from 19.5 hours to just 4.5 hours. Apple says the devices should operate for up to 10 hours between charges.

The MacBook Pro laptops were not as well-received as Apple would have hoped for due to issues ranging from battery life, cost, dongles required, loss of function keys, price and the fact that the chip was rather elderly.

Consumer Reports has not confirmed that it's working with Apple, so we will just have to take Jobs’ Mob word for it.
