iOS 15

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.[3]

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 iPod Touch, as its successor, iOS 16, drops support for those models, including the seventh-generation iPod Touch.[4]

System features[edit]

Focus[edit]

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 a time.[5]


Focus also controls the interactions with Contacts, so it is possible to decide which specific contacts can "disturb" the user.[6]


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.[7]


Focus is synchronized automatically across different iOS, iPadOS, and macOS devices on the same iCloud account, as well as any paired watchOS devices.[8]

Notifications[edit]

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.[9]


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.[10]

Live Text[edit]

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.[11]

Smart stacks with suggested Widgets[edit]

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.[12]

Cross-App Drag and Drop[edit]

Pictures and text can be dragged from one app and dropped in another. This feature was previously only available in iPadOS.[13]

Home[edit]

The various Home screens can be reordered, deleted, hidden, or limited using Focus mode.[14]

Per-App Text Size[edit]

From the Control Center, the text size can be set per app.[13]

Spotlight[edit]

The global search function has been enhanced and it is also available on the lock screen by pulling the page down.[15]

Dictation[edit]

Formerly limited to 60 seconds, the Voice-To-Text dictation time available in the keyboard is unlimited.[16]

System-wide translation[edit]

System-wide translation allows the user to translate text in all apps by selecting it and tapping on the Translate option.[17]

Adjust video playback speed[edit]

The system default player, used for videos and by many apps, supports changing playback speed.[18]

Video Effects and Mic Mode[edit]

The Control Center supports Video Effects, adding Portrait effect to the camera, and Mic Mode to implement microphone Voice Isolation.[19]

App features[edit]

FaceTime[edit]

iOS 15 adds several new features to FaceTime including:[30]

Security and privacy[edit]

App Privacy Report[edit]

By activating this app logging, the user can save a 7-day summary of the times when the various apps access certain data and the domains or websites they visit. This feature was called "Record App Activity" until iOS 15.2, when its functionality was extended.[59]

Siri Improved Privacy[edit]

On devices with an Apple A12 chip or later, Siri now converts audio into words on the device itself instead of sending it to Apple servers.[60]

Hide IP address for trackers in Safari[edit]

Safari's anti-tracking now prevents known trackers from reading the user real IP address.[61]

Hide IP address for external content in Mail[edit]

In the Mail app, the user can enable the setting to hide their IP address when downloading external content that may be present in a mail message. In this way it is possible to privately download this external content without being tracked by spammers or commercial companies that have inserted them without the user's knowledge.

Hide My Email[edit]

Hide My Email creates random email addresses that forward to the inbox so e-mail can be sent and received anonymously.

iCloud Private Relay[edit]

Private Relay masks the user's IP address in Safari, preserving the region without revealing the actual location. It also protects the DNS query resolution and insecure HTTP traffic in all apps.

Built-in one-time password authenticator With Autofill[edit]

The built-in authenticator allows iOS devices to be used to generate verification codes for additional sign-in security of accounts. There is no need to download a separate app because it is integrated into the OS. The verification codes are automatically filled when a user signs in to the site.

WPA3 Hotspot[edit]

Hotspot connections now can also use the WPA3 security protocol.[62]


Tethering to/from older iOS devices is not possible as WPA2 compatibility is not fully supported.

CSAM detection[edit]

CSAM detection identifying known Child Sexual Abuse Material (CSAM) in photos stored iCloud Photos was originally intended to be included. Implementation of CSAM detection was delayed indefinitely,[63] and cancelled altogether in December 2022.[64] This recognition is based on a perceptual hash called NeuralHash.[65]


Siri and Search were updated to intervene when users perform searches for queries related to CSAM. The Messages app will warn children when receiving or sending sexually explicit photos, blurring sent and received photos.[66] It was originally planned to also notify parents of children under 13 if they choose to view flagged messages anyway, but this was removed due to concerns about abusive parents.[67]
