Key Features of iOS 15

FaceTime Upgrades

iOS 15 introduced significant updates to FaceTime to make video calls feel more natural. Key additions include:

• Spatial Audio: Spreads out voices so they sound like they are coming from the direction the speaker is positioned on the screen.
• Voice Isolation and Wide Spectrum: Filters out background noise or captures surrounding sound depending on your preference.
• SharePlay: Allows users to share experiences by watching movies, listening to music, or sharing their screen during a call.
• Web Support: Non-Apple users can join FaceTime calls via a web browser using generated invite links.

Focus Mode

Focus is an evolution of Do Not Disturb that helps users reduce distractions. It allows you to filter notifications and Home Screen pages based on your current activity—such as Work, Personal, Fitness, or Sleep. When a Focus is active, your status can automatically display in Messages to let others know you are temporarily unavailable.

Redesigned Notifications

Notifications in iOS 15 feature contact photos for people and larger icons for apps, making them easier to identify. A "Notification Summary" feature collects non-urgent notifications and delivers them in a single batch at scheduled times during the day.

Live Text and Visual Look Up

Using on-device intelligence, Live Text recognizes text within photos, screenshots, and the Camera viewfinder. Users can copy text, make phone calls from a handwritten number, or translate languages directly from an image. Visual Look Up allows users to learn more about popular art, landmarks, plants, and pets found in their photo library.

Safari Redesign

Safari received a major interface overhaul in iOS 15. The address bar was moved to the bottom of the screen by default for easier one-handed reach, allowing users to swipe between open tabs. Users can also organize tabs into "Tab Groups" that sync across Apple devices.

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.
