Apple added the Action button to the iPhone 15 Pro, but more could be on the way for the iPhone 16. This is what the rumor mill believes is on the way.
Exclusive: Apple is internally testing improved versions of its built-in Music and QuickTime apps, which in iOS 18 and macOS 15 will gain support for smooth audio transitions and a new "Passthrough" feature.
Battery life is perhaps the most vital part of the iPhone experience. This is what the rumor mill expects will change power-wise with the iPhone 16 and iPhone 16 Pro series.
