iOS 15 is the fifteenth major release of Apple's iOS operating system, developed for the iPhone and iPod Touch lines.

A primary highlight of iOS 15 is the overhaul of communication tools. FaceTime received significant upgrades, introducing spatial audio, voice isolation to reduce background noise, a grid view for group calls, and SharePlay, which allows users to watch movies, listen to music, or share their screens together in real time. Additionally, FaceTime links enabled Android and Windows users to join calls via a web browser for the first time.

To improve productivity and minimize digital distractions, iOS 15 introduced Focus modes. Users can filter notifications and home screen pages based on their current activity, such as working, sleeping, or personal time. Notifications were also redesigned with larger app icons, contact photos, and a scheduled Notification Summary that delivers a collection of non-urgent alerts at designated times of the day.

On-device intelligence was expanded through features like Live Text, which recognizes text in photos and allows users to copy, paste, look up, and translate it directly from the Camera app or saved images. Spotlight search was also upgraded to search web images and photos by location, people, scenes, or objects.

Other notable additions include a redesigned Safari browser with a bottom tab bar and Tab Groups, interactive globe and 3D city views in Apple Maps, and enhanced privacy tools such as Mail Privacy Protection and the App Privacy Report. iOS 15 supports all devices capable of running iOS 14, ranging from the iPhone 6s and iPhone SE (1st generation) up to modern models.
