The biggest changes to the iPhone 15 lineup are likely to come at the edges when Apple announces new products Tuesday.
What’s happening: Apple’s flagship phone is expected to add better cameras, a titanium casing and swap the proprietary Lightning port for a more standard USB-C connector.
Why it matters: Each year Apple aims to make the new iPhones compelling enough to convince a significant chunk of existing owners to upgrade, a task that has become harder as the years have gone on.
Details: Apple is holding its annual iPhone event at 10 a.m. Tuesday in the Steve Jobs Theater at its Apple Park headquarters in Cupertino. Calif.
