Squeezed somewhere between the headphone jack, waterproofing and new home button info at Apple’s iPhone 7 launch event was a little announcement about the handset’s display. According to Apple, it’s 25% brighter than the one of the iPhone 6S, capable of hitting a top mark of 625 nits.
However, in recent days there've been multiple reports from users shedding doubt on Apple’s claims, with plenty of new iPhone owners -- the ones rich enough to own a 7 and a 6S, anyway -- struggling to spot any difference between the old and new displays.
A report from the people at DisplayMate explains why.
“On the iPhone 7 the Maximum Screen Brightness can go much higher when Automatic Brightness is turned On, so that users can’t permanently park the Manual Brightness slider to very high values, which would run down the battery quickly,” it reads. “High Screen Brightness is only needed for High Ambient Light, so turning Automatic Brightness On will provide better high ambient light screen visibility and also longer battery running time.”
So, to preserve battery you can only hit peak brightness with Automatic Brightness -- a feature you should always have switched on -- enabled, but that’s not all. DisplayMate has also worked out that peak brightness is actually 705 nits, significantly higher than Apple’s claimed figure.
