There are a handful of new features added to the Photos app in iOS 16, including a nifty photo and video detection system that automatically finds duplicate images, making it quicker for you to clean up your camera roll and free up much-needed storage space. Duplicates may refer to exact photo or video copies that bear slightly different metadata, or media files that have been saved on the mobile device more than once. They could also be photos that look alike at first glance, but may actually have slight differences, such as file formats or resolution rates.
Any duplicates that have been automatically identified will be conveniently stored into an iPhone album called “Duplicates,” which can be found by launching the Photos app, tapping on “Albums,” and scrolling down to the “Utilities” section. When you are in the right album, duplicate photos and videos should be seen conveniently arranged next to each other, so you’ll have an easier time reviewing them. You have the choice of either deleting any of the duplicates, or simply merging the files into one that can be saved in your iPhone photo library.
