iOS 15 is the fifteenth major release of the iOS mobile operating system developed by Apple for its iPhone and iPod Touch lines of products. It was announced at the company's Worldwide Developers Conference on June 7, 2021, as the successor to iOS 14 and released to the public on September 20, 2021.
On June 6, 2022, at WWDC 2022, its successor, iOS 16, was announced. iOS 15 was officially succeeded by iOS 16 on September 12, 2022.
iOS 15 is the final version of iOS that supports the iPhone 6s & 6s Plus, first-generation iPhone SE, iPhone 7 & 7 Plus, and seventh-generation iPod Touch, as its successor, iOS 16, drops support for those models. This means that iOS 15 is the last version to support the iPod Touch. iOS 15 is also the final iOS version to support live wallpapers. The current version available for these models is iOS 15.8.8, which released on May 11, 2026.
System features Focus Replacing the dedicated Do Not Disturb feature introduced in iOS 6, Focus is a new feature that allows a user to change their "state", such as Work, Sleep, Do Not Disturb or a custom focus. Based on the selected state, users can set the type of notification they want to receive and from which application. It is also possible to choose which pages and then apps to show on the Home based on the state. The state can change automatically based on where the user is or the time of day.
Focus also controls the interactions with Contacts, so it is possible to decide which specific contacts can "disturb" the user.
Some Lock Screen settings can be controlled based on the state: for example, the Dim Lock Screen feature, which darkens the lock screen from not showing notifications on that screen, can be automatically turned on or off based on the state.
Focus is synchronized automatically across different iOS, iPadOS, and macOS devices on the same iCloud account, as well as any paired watchOS devices.
Notifications Notifications receive a new look with contact photos for all communication apps and larger app icons. When the notification arrives, the user can mute the corresponding app for one hour or all day.
The Summary allows the user to group and postpone the notifications coming from the chosen apps, delivering them at a scheduled time in a single big notification called summary notification.
Live Text Devices with an A12 chip or later support Live Text, which uses optical character recognition to recognize text in images, allowing copy-and-paste, look-up, and translation in Photos, Screenshot, Quick Look, Safari, and Live Preview with Camera. This feature uses artificial intelligence text recognition using the Neural Engine.
Smart stacks with suggested widgets The Widgets in iOS 15 are now more dynamic: depending on the context, the system can add or remove widgets to existing stacks. For example, near the start of a certain event in the Calendar, the system can decide to add the Calendar Widget to an existing smart stack, if it is not already present, and then remove it at the end of the event.
Cross-app drag and drop Pictures and text can be dragged from one app and dropped in another. This feature was previously only available in iPadOS.
Home screen The various home screens can be reordered, deleted, hidden, or limited using Focus mode.
Per-app text size From the Control Center, the text size can be set per app.
Spotlight The global search function has been enhanced and it is also available on the lock screen by pulling the page down.
Dictation Formerly limited to 60 seconds, the Voice-To-Text dictation time available in the keyboard is unlimited.
System-wide translation System-wide translation allows the user to translate text in all apps by selecting it and tapping on the Translate option.
Adjust video playback speed The system default player, used for videos and by many apps, supports changing playback speed.
Video Effects and Mic Mode The Control Center supports Video Effects, adding Portrait effect to the camera, and Mic Mode to implement microphone Voice Isolation.
Accessibility improvements Per-App Accessibility: each app can have a different accessibility setting to customize the text (Bold Text, Larger Text, Button Shapes, On/Off Labels, Reduce Transparency), increase contrast, reduce motion, autoplay video-preview, etc. Image Exploration with VoiceOver: it describes photos to give users with low vision more context about what's displayed on the photo. Audible charts: the Audio Graphs accessibility framework allows to represent chart data with audio for blind and low-vision people.
iCloud Backups to iCloud can now also be made on 5G cellular networks.
RealityKit 2 This version for augmented reality (AR) uses new APIs to capture objects faster, and supports custom shaders, dynamic assets, custom systems and character control.
Accounts for school and work User accounts managed by an organization, such as work or school accounts, can be added without requiring external apps or profiles.
StoreKit 2 StoreKit 2 allows apps to implement the "Request a Refund" option in-app. The users can tap this option, select a specific in-app purchase and identify the problem that led to the refund request. It also allows developers to monitor the purchases made by their users without using third-party solutions.
