- The iPhone Duo Guide names it for multitasking, photos and video and travel.Multitasking: Run two apps side by side on the 7.6-inch inner screen, then fold it to a 5.4-inch phone; Apple Pencil works too. Our readPhotos and video: Two 48MP rear cameras, plus a front camera for each screen, so video calls work open or closed. Our readTravel: On a long flight the outer screen plays up to 44 hours of video, and 20 minutes on a 60W adapter brings it to 50%. Our read
The iPhone 18 Pro Guide does not name what it is best for yet, so this list does not compare the two.
