Key Features in iOS 15

FaceTime Upgrades

iOS 15 introduced major enhancements to FaceTime to make video calls more natural and collaborative:

• Spatial Audio: Spreads out voices so they sound like they are coming from the direction of the speaker on screen.
• Voice Isolation: Uses machine learning to block out ambient background noise.
• SharePlay: Enables users to watch movies, listen to music, or share their screen in real time during a call.
• Cross-Platform Links: Allows Android and Windows users to join FaceTime calls via a web browser.

Focus Mode and Redesigned Notifications

To minimize distractions, iOS 15 introduced Focus mode, a system that filters notifications and Home Screen pages based on current activity, such as Work, Personal, Sleep, or Fitness.

Notifications were redesigned with contact photos and larger app icons for easier identification. A Notification Summary feature aggregates non-urgent alerts into a scheduled daily digest delivered at times specified by the user.

Live Text and Visual Look Up

Using on-device intelligence, the Live Text feature recognizes text in photos, screenshots, and the Camera app. Users can select, copy, translate, or search for text directly from an image, as well as tap phone numbers to make calls or tap addresses to open Maps. Visual Look Up allows users to identify objects like plants, pets, and landmarks captured in photos.

Safari Redesign

Safari received a significant interface overhaul in iOS 15, moving the address bar to the bottom of the screen for easier one-handed reach. The update introduced Tab Groups, allowing users to organize and sync groups of tabs across Apple devices, along with support for web extensions.

Privacy Enhancements

Privacy protections were expanded to give users more control over their personal data:

• Mail Privacy Protection: Prevents senders from learning your IP address or seeing if you opened an email.
• On-Device Siri Processing: Enables voice commands to be processed locally without an internet connection, improving both speed and privacy.
• App Privacy Report: Provides visibility into how frequently apps access sensitive permissions like location, photos, camera, and microphone.

Device Compatibility

Apple maintained broad hardware support for iOS 15, making it compatible with all devices capable of running iOS 14. This includes the iPhone 6s and newer, the first- and second-generation iPhone SE, and the seventh-generation iPod Touch.
