Following extremely puzzling Consumer Reports tests that showed the 2016 MacBook Pro offering substantially better battery-life than Apple claimed, a UK consumer-testing organization has reported the same thing.
Which found in tests of 67 laptops that Apple was the only manufacturer to deliver greater than promised, while other manufacturers delivered as little as half the claimed life.
As with the previous report, though, I’m struggling to understand the stated results …
Which says that a 13-inch MacBook Pro delivered 12 hours of battery life against the claimed 10 hours. Unhelpfully, the organization doesn’t specify which specific model this relates to, stating only that the results apply to laptops tested since January 2016. This means that it could be the old Retina model, the 2016 model without Touch Bar or the 2016 model with Touch Bar.
The result isn’t as crazy as those from Consumer Reports, and the testing regime does sound reasonable.
We test laptops for battery life while actively browsing the web over wi-fi, running the laptop in this fashion until the battery is fully drained […] Each laptop we judge goes through our battery tests at least three times. We […] drain the whole battery from start to finish, several times over, during various tasks. One test involves watching films until the battery finally shuts down, another continually browsing websites over wi-fi.
But neither I nor any of the colleagues at 9to5Mac I asked are seeing anything like this with our 2016 models. If I shut down unwanted apps and run at four notches below maximum brightness, I typically see 6-7 hours. If I keep all my usual apps open, and run at my standard brightness of two notches below maximum, that falls to 4-5 hours.
In a poll we ran back in December, the largest group of readers were seeing five hours or less from their new machines. I honestly cannot understand how either organization is seeing greater than 10 hours unless they are setting the screen brightness crazily low.
But for what it’s worth, the laptops with the most misleading battery life claims were these:
Lenovo Yoga 510: Claimed battery life: 5 hours, Which? tests: 2 hours, 7 minutes
HP Pavilion 14-al115n: Claimed battery life: 9 hours, Which? tests: 4 hours 25 minutes
Dell Inspiron 15 5000 Claimed battery life: 7 hours, Which? tests: 3 hours 58 minutes
Acer E15 Claimed battery life: 6 hours, Which? tests: 2 hours 56 minutes
Since it’s been a while since that first poll, and readers will now have a lot more experience with their machines, we’re running a fresh poll to get updated figures. We’ve also expanded the options to distinguish between 5 hours and less than 5 hours. Please take part if you own a 2016 MacBook Pro, and share your experiences in the comments.
