Consumer Reports has now finished retesting the battery life on Apple’s new MacBook Pro laptops, and our results show that a software update released by Apple on January 9, fixed the problems we had met in the earlier tests.
With the updated software, the three MacBook pro’s in our labs already performed well, with one model, 18.75 hours on a charge. We tested each model several times using the new software, according to the same protocol applies to the hundreds of laptops per year.
We have first a review of the MacBook Pro laptops in December, and found that the longevity of the results are very inconsistent from one test to the next. (She walked to a low of 3.75 hours to 19.5 hours between charges.) That resulted in the laptops will receive a low overall scores, despite the strong performance in areas such as display quality and performance.
The process that we followed with Apple is the same process that we follow with any by the manufacturer, when we discover a big problem. We shared our testing results with the company, so that it could better understand our findings, and provide a solution for the consumer. Since Apple is a fix, we tested it with the laptops.

Now that we have factored in the new battery-life measurements, the laptops the overall scores have increased, and all three machines now also fall within the recommended range in Consumer Reports reviews.
The three MacBook pro’s in our laboratories are two of the 13-inch models, one with Apple’s new Touch-Bar and one without the Touch Bar, and a 15-inch model. (All 15-inch MacBook pro’s come with the Touch Bar.) The new average battery-life results are, in order, 15.75 hours, 18.75 hours and 17.25 hours. We bought the three computers in the retail sector, as we do with other products reviewed by Consumer Reports, to ensure that the tests of the same models that a consumer would buy.
Apple’s updated software is available through Apple’s Beta Software Program and will be rolled out in a full Software Update for all users within a number of weeks.
