Apple says Consumer Reports MacBook Pro battery testing used flawed methods



Final month, Consumer Reports got here up with some interesting battery test results with the newest MacBook Pro fashions. Outcomes ranged from 3.75 hours to 19.5 hours. Many within the Apple group thought that one thing was off, both a software bug or a benchmarking difficulty — it seems it was each.

Apple labored with Consumer Reports over the vacations to seek out out why the battery check outcomes different a lot. It’s arduous to get the very same battery life each time. That’s why benchmark lovers run a check a number of occasions to seek out the typical outcome.

And but, battery life shouldn’t range from 1x to 5x. Many early consumers have already been complaining concerning the battery lifetime of the new MacBook Pro. That’s why Apple removed the “battery time remaining” estimate in a macOS replace.

However it doesn’t clarify Consumer Reports’ benchmark. It seems that Consumer Reports turns off Safari’s native cache for his or her searching check. It signifies that the browser will fetch an internet site’s knowledge from the web each time. When the cache is on, Safari shops photographs on your exhausting drive so that you simply don’t need to load them up each time.

“Consumer Reports makes use of a hidden Safari setting for creating web pages which turns off the browser cache. This isn’t a setting used by clients and doesn’t mirror actual-world utilization,” Apple stated in a press release.

This appears deliberate, and Consumer Reports explains why in a new post today. The publication turns off the cache settings on the default browser for all laptops — not simply Mac laptops. This manner, it’s like Consumer Reports is searching hundreds of various web sites, and never simply the identical ten web sites time and again.

Apple has additionally found that there was a bug in Safari affecting icon fetching. This bug has been fastened — this could enhance benchmarks.

However it makes you consider Consumer Reports’ methodology right here. Utilizing net searching for battery benchmarks looks like an incredible concept. It imitates actual life utilization as most individuals use their pc to browse the web, play music, write paperwork and spreadsheets and play films. However deactivating default settings that positively have an effect on battery life appears curious. Perhaps Consumer Reports ought to contemplate leaving the cache on for future Mac and PC laptop computer benchmarks.

Apple despatched the next assertion to TechCrunch:

“We respect the chance to work with Consumer Reports over the vacations to know their battery check outcomes. We discovered that when testing battery life on Mac notebooks, Consumer Reports makes use of a hidden Safari setting for creating web pages which turns off the browser cache. This isn’t a setting used by clients and doesn’t mirror actual-world utilization. Their use of this developer setting additionally triggered an obscure and intermittent bug reloading icons which created inconsistent leads to their lab. After we requested Consumer Reports to run the identical check utilizing regular consumer settings, they advised us their MacBook Pro techniques persistently delivered the anticipated battery life. We’ve got additionally fastened the bug uncovered on this check. That is the best professional pocket book we’ve ever made, we respect Consumer Reports and we’re glad they determined to revisit their findings on the MacBook Pro.”
