Apple has broadened the availability of the Dynamic Island feature, which was previously limited to the iPhone 14 Pro models, to all versions of the iPhone 15. This Dynamic Island substitutes the conventional notch, providing a more engaging visual experience. The iPhone 15 and 15 Plus showcase 6.1-inch and 6.7-inch displays with a peak outdoor brightness of 2,000 nits—double that of their predecessors.
