Key Features Introduced in Apple iOS 15

Apple released iOS 15 with a strong focus on keeping users connected, enhancing productivity, and introducing advanced on-device intelligence. This release brought substantial updates across the operating system, including major overhauls to FaceTime, a smarter Notification management system, redesigned core apps like Safari and Apple Maps, and powerful new machine-learning features such as Live Text.

FaceTime Enhancements and SharePlay

FaceTime received significant audio and video upgrades designed to make calls feel more natural:

  • Spatial Audio and Voice Isolation: Audio sounds as if it originates from the direction of the speaker on the screen, while Voice Isolation blocks out background noise.
  • Portrait Mode: Users can blur their background during video calls.
  • Cross-Platform Links: FaceTime links can be generated to invite users on Android and Windows to join calls via a web browser.
  • SharePlay: This feature allows users to share synchronized media—such as movies, TV shows, and music—directly within a FaceTime conversation, alongside screen sharing.

Focus Modes and Redesigned Notifications

To minimize distractions, iOS 15 introduced a revamped notification experience and dedicated Focus profiles:

  • Focus: Users can filter notifications and home screen pages based on current activity, such as Work, Personal, Fitness, or Sleep. Setting a Focus on one Apple device automatically applies it to others.
  • Notification Summary: Non-urgent notifications are bundled together and delivered at scheduled times of the day to reduce interruptions.
  • Visual Redesign: Notification banners feature larger app icons and contact photos to make them easier to identify.

Live Text and Visual Look Up

Using on-device intelligence, iOS 15 added advanced image recognition capabilities:

  • Live Text: The camera and Photos app can recognize text within any image. Users can highlight, copy, translate, or interact with text, such as tapping a phone number to place a call.
  • Visual Look Up: Users can learn more about popular art, landmarks, plants, and pet breeds captured in their photos.

Redesigned Safari

Safari received an updated layout focused on single-handed navigation:

  • Bottom Tab Bar: The address bar was moved to the bottom of the screen to make it easier to reach, allowing quick swiping between open tabs. Users also have the option to revert to the classic top layout.
  • Tab Groups: Users can organize tabs into categorized groups that automatically sync across iPhone, iPad, and Mac.
  • Web Extensions: Mobile Safari added full support for third-party web extensions from the App Store.

Upgraded Apple Maps

Maps gained richer visual details and improved navigation tools:

  • Enhanced City Details: Select cities received 3D renderings of landmarks, custom-designed icons, elevation data, and specialized road details like turn lanes and crosswalks.
  • Immersive Walking Directions: Users can scan nearby buildings with the camera to get augmented reality, step-by-step walking directions.
  • Interactive Globe: A detailed 3D globe visualization was introduced for exploring continental geography.

Privacy Protections

iOS 15 introduced several core privacy safeguards:

  • Mail Privacy Protection: Prevents email senders from learning a user's IP address or knowing if and when an email was opened.
  • App Privacy Report: A dedicated section in Settings that displays how frequently apps access sensitive data, such as location, microphone, and contacts, as well as the network domains they contact.
  • On-Device Siri Processing: Audio requests made to Siri are processed entirely on-device by default, improving both privacy and speed.

Apple Wallet and Health

  • Digital Keys and IDs: Wallet expanded beyond credit cards to support digital car keys, home keys, hotel room keys, and state driver's licenses.
  • Health Sharing and Trends: The Health app added features to securely share health data with family members or physicians, alongside Walking Steadiness metrics to evaluate fall risk.
