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]
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 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]
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]
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]
Pictures and text can be dragged from one app and dropped in another. This feature was previously only available in iPadOS. [13]
The various Home screens can be reordered, deleted, hidden, or limited using Focus mode. [14]
From the Control Center, the text size can be set per app. [13]
The global search function has been enhanced and it is also available on the lock screen by pulling the page down. [15]
Formerly limited to 60 seconds, the Voice-To-Text dictation time available in the keyboard is unlimited. [16]
System-wide translation allows the user to translate text in all apps by selecting it and tapping on the Translate option. [17]
The system default player, used for videos and by many apps, supports changing playback speed. [18]
The Control Center supports Video Effects, adding Portrait effect to the camera, and Mic Mode to implement microphone Voice Isolation. [19]
Backups to iCloud can now also be made on 5G cellular networks. [16]
This version for augmented reality (AR) uses new APIs to capture objects faster, and supports custom shaders, dynamic assets, custom systems and character control. [23] [24] [25] [26]
User accounts managed by an organization, such as work or school accounts, can be added without requiring external apps or profiles. [27]
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. [28] It also allows developers to monitor the purchases made by their users without using third-party solutions. [29] [ better source needed ]
iOS 15 adds several new features to FaceTime including: [30]
Memoji in iOS 15 have more customization options, including new clothing, two different eye colors, new glasses, new stickers, multicolored headwear, and new accessibility options. [31]
Apple Maps receives several new features: [35]
The Photos app can now manually set the time, date, and location of a photo. The app also allows the user to view information about the photo such as the camera used to take the photo and the photo's file size. [37] [38] In the Photos app, the user can now look up places that are inside images, however, this feature only works on the Apple A12 chip or later. [39] [40] [41] [42]
Improved panoramic shooting mode on iPhone 12 and above: less geometric distortion in panoramic shots with elongated fields of view, noise and banding reduction that are formed in the image due to changes in brightness and contrast when moving the camera from side to side, a less blurry and clearer image even when capturing moving subjects within the panorama. [43]
Safari was completely redesigned, moving the tab bar and address bar to the bottom of the screen, but there is an option to keep the legacy layout. It now has tab groups, allowing users to organize tabs and share entire groups of tabs. The user can now use a pull to refresh gesture to refresh a webpage. [44] Browser extensions are available for the first time in Safari for iOS; they are the same extensions available in Safari for the Mac. [45] Safari will automatically upgrade HTTP URLs to HTTPS if compatible. The WebM video container is supported.
Safari opens with a new start page; it is possible to have a custom page on startup that contains sections including favorites, most frequently visited sites, Siri suggestions, etc. [46]
App Clips more discoverable: it is possible to show a full-screen preview of the app clip in Safari.
Weather received an overhaul, with new animations and weather maps in full screen, and the weather icon was updated. The app also has a next-time precipitation notifications feature which allows the user to get a notification whenever rain or snow is going to start or stop within the next hour for the user's current location and each saved location, independently. [47]
Siri can now work offline on iPhones with an A12 Bionic chip or later, responding faster to common requests supported locally without need for Internet connection. [48] [49]
Apple News has been completely redesigned, featuring more rounded corners. [50] [ failed verification ]
Siri responds to requests such as "Hey Siri, share this with [name]" or "send this to [name]" to share screen content using Messages. Items such as images, web pages, Apple Music or Podcasts, Apple News stories, and Maps locations will share the actual content (or a link to it). For content Siri cannot share, Siri will send a screenshot, notifying the user.
Announce Notifications: with announce notifications update in iOS 15, Siri can read all incoming notifications aloud and allow users to speak a response to them. This can be enabled for specific apps.
Health data can now be shared. [51] [ better source needed ] [52] [53] [54]
A new monitored parameter called "Walking Steadiness" has been added, which determines the risk of falling using gyroscopic sensors that measure balance, stability, and coordination. [51] [ better source needed ] [52] [53]
Added the Trend analysis i.e. horizontal lines that show the trend of the various parameters over the long term. [51] [ better source needed ]
Lab Results allows the user to import laboratory results into the Health app from a healthcare provider.
Groups is a new view mode that groups files of the same type.
The built-in PDF editor can insert pages from existing files or scans, remove pages, and rotate pages. PDFs can also be locked with a password. [55]
New #tags allow classifying, organizing, then finding the user's notes faster. Smart Folders automatically group various notes based on tags. Ability to share notes with other collaborators and work on them together. The activity view shows a summary of the changes made by other collaborators before the user's last reading and a day-by-day list of the activities carried out by each collaborator. It is possible to mention @someone in the notes, who will be notified.
Ability to insert #tags in reminders to classify them.
Added new playback options to adjust speed and skip silence.
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]
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]
Safari's anti-tracking now prevents known trackers from reading the user real IP address. [61]
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 creates random email addresses that forward to the inbox so e-mail can be sent and received anonymously.
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.
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.
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 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]
iOS 15 introduced kalloc_type
in order to advance memory safety in the XNU kernel. This is primarily to mitigate privilege escalation vulnerabilities. [68]
