When you copy text, a code snippet, or an address, the iPhone 17 Pro Max suggests relevant actions in the destination app. For example, pasting an address in Messages might suggest sharing your ETA via Maps.

15. Personalized Spatial Audio Profiles

Take your AirPods Pro experience to the next level. Using the iPhone 17 Pro Max’s TrueDepth camera, you can create a personalized spatial audio profile that maps the unique shape of your head and ears. Go to Settings > Bluetooth > Your AirPods > Personalized Spatial Audio and follow the setup for unparalleled immersive sound.

16. Advanced Data Protection (Full End-to-End Encryption)

For maximum security, turn on Advanced Data Protection in Settings > [Your Name] > iCloud > Advanced Data Protection.
