iOS 17, released on September 18, 2023, introduces several enhancements that elevate the iPhone experience. Notable features include Contact Posters, allowing users to personalize their call screens with custom images and fonts, and Live Voicemail, which provides real-time transcription of incoming voicemails, enabling users to decide whether to answer calls based on the displayed text.

The keyboard's autocorrect functionality has been improved with a new on-device transformer model, offering more accurate and personalized corrections. Additionally, the StandBy feature displays information via widgets, live activities, and photos when the phone is charging in a horizontal orientation.

iOS 17 is compatible with iPhone models from the XS and XR onwards, including the iPhone SE (2nd generation) and later. However, it does not support the iPhone 8, 8 Plus, and X models.
