iOS 9 was introduced at the Apple Worldwide Developers Conference on June 8, 2015, with the first beta version made available to registered developers after the keynote, and a public beta made available in July.{{cite web |first=Dan |last=Seifert |title=Apple announces iOS 9, release later this year |url=https://www.theverge.com/2015/6/8/8730557/apple-ios9-release-wwdc-2015 |website=The Verge |publisher=Vox Media |date=June 8, 2015 |access-date=December 20, 2016 |url-status=live |archive-url=https://web.archive.org/web/20170206023203/http://www.theverge.com/2015/6/8/8730557/apple-ios9-release-wwdc-2015 |archive-date=February 6, 2017 }}{{cite web |first=Andrew |last=Griffin |title=iOS 9 beta: users can sign up for beta scheme to get new iPhone operating system in July |url=https://www.independent.co.uk/life-style/gadgets-and-tech/news/ios-9-beta-users-can-sign-up-for-beta-scheme-to-get-new-iphone-operating-system-in-july-10306392.html |website=The Independent |date=June 8, 2015 |access-date=December 20, 2016 |url-status=live |archive-url=https://web.archive.org/web/20160729221113/http://www.independent.co.uk/life-style/gadgets-and-tech/news/ios-9-beta-users-can-sign-up-for-beta-scheme-to-get-new-iphone-operating-system-in-july-10306392.html |archive-date=July 29, 2016 }}{{cite web |first=Sophie |last=Curtis |title=iOS 9: what we've learnt from WWDC 2015 |url=https://www.telegraph.co.uk/technology/apple/11662734/iOS-9-everything-we-know-after-WWDC-2015.html |website=The Daily Telegraph |date=June 9, 2015 |access-date=December 20, 2016 |url-status=live |archive-url=https://web.archive.org/web/20160304051528/http://www.telegraph.co.uk/technology/apple/11662734/iOS-9-everything-we-know-after-WWDC-2015.html |archive-date=March 4, 2016 }}

This marked the first time that the general public had been able to test new versions of iOS before official release, with Eddy Cue, Apple's Senior Vice President of Internet Software and Services, telling Fast Company that the public beta program was started "because of Maps", referring to the company's Apple Maps launch that had significant issues in its early days.{{cite web |first=Rick |last=Tetzeli |title=Playing The Long Game Inside Tim Cook's Apple |url=https://www.fastcompany.com/3062090/tim-cooks-apple/playing-the-long-game-inside-tim-cooks-apple |website=Fast Company |publisher=Mansueto Ventures |date=August 8, 2016 |access-date=July 5, 2017 |url-status=live |archive-url=https://web.archive.org/web/20170414121749/https://www.fastcompany.com/3062090/tim-cooks-apple/playing-the-long-game-inside-tim-cooks-apple |archive-date=April 14, 2017 }}{{cite web |first=Chris |last=Welch |title=Apple created the iOS public beta because its Maps app was so bad |url=https://www.theverge.com/2016/8/8/12401638/apple-created-ios-beta-because-maps |website=The Verge |publisher=Vox Media |date=August 8, 2016 |access-date=July 5, 2017 |url-status=live |archive-url=https://web.archive.org/web/20161113052020/http://www.theverge.com/2016/8/8/12401638/apple-created-ios-beta-because-maps |archive-date=November 13, 2016 }}

On the iPhone 6s and iPhone 6s Plus, a touch-sensitive display feature called 3D Touch is incorporated into iOS 9. It is similar to Force Touch, which can be found on the trackpad of some Apple MacBook computers. Quick Actions and shortcuts are added to apps that support the 3D Touch feature and are triggered by pressing slightly harder on the app icon. It also introduces actions known as Peek and Pop, which lets users firmly hold to preview ("Peek") any kind of content in a hovering window, before they optionally apply more pressure to enter ("Pop") the content into full view.{{cite web|url=http://www.macrumors.com/how-to/iphone-6s-3d-touch/|title=How to Use 3D Touch on iPhone 6s and 6s Plus|last=Gil|first=Lory|date=October 30, 2015|website=MacRumors|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20161121223000/http://www.macrumors.com/how-to/iphone-6s-3d-touch/|archive-date=November 21, 2016}}

iOS 9 comes with two important battery-saving updates. When a phone has been placed face-down, the screen will not light up upon receiving notifications. Apple has also added Low Power Mode, which modifies the amount of energy dedicated to background services and animations. For example, background app refresh and push email are paused during Low Power Mode. When a phone reaches 20% battery level, users are automatically prompted to turn on Low Power Mode, which changes the color of the battery icon in the top row status bar on the screen to yellow.{{cite web|url=https://www.cnet.com/how-to/how-to-use-low-power-mode-on-ios-9/|title=How to use low-power mode on iOS 9|last=Cipriani|first=Jason|date=July 16, 2015|website=CNET|publisher=CBS Interactive|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20161221090254/https://www.cnet.com/how-to/how-to-use-low-power-mode-on-ios-9/|archive-date=December 21, 2016}} When the battery goes higher than the 80% level, Low Power Mode automatically turns back off.{{cite web|url=http://bgr.com/2015/09/29/ios-9-batter-life-trick-low-power-mode/|title=This obvious iOS 9 trick helps your iPhone battery last much longer|last=Smith|first=Chris|date=September 29, 2015|website=BGR|publisher=Penske Media Corporation|access-date=October 12, 2017|url-status=live|archive-url=https://web.archive.org/web/20171013013454/http://bgr.com/2015/09/29/ios-9-batter-life-trick-low-power-mode/|archive-date=October 13, 2017}}

iOS 9 is a smaller update than iOS 8, requiring just 1.3 GB of space, compared to 4.58 GB for iOS 8.{{cite web|url=http://www.macrumors.com/2015/06/23/ios-9-app-delete-reinstall-os-update-feature/|title=iOS 9 Includes New Auto App Delete/Reinstall Feature for OS Updates on Devices With Insufficient Space|last=Clover|first=Juli|date=June 23, 2015|website=MacRumors|access-date=January 8, 2017|url-status=live|archive-url=https://web.archive.org/web/20170103003255/http://www.macrumors.com/2015/06/23/ios-9-app-delete-reinstall-os-update-feature/|archive-date=January 3, 2017}} Additionally, iOS 9 includes an option to temporarily delete apps to allow the update to install. Once the update has been installed, the apps will be automatically reinstalled from the App Store.{{cite web|url=https://www.theverge.com/2015/6/23/8834059/apple-ios-9-can-temporarily-delete-apps-before-updates|title=iOS 9 can temporarily delete apps to make room for software updates|last=Welch|first=Chris|date=June 23, 2015|website=The Verge|publisher=Vox Media|access-date=January 8, 2017|url-status=live|archive-url=https://web.archive.org/web/20170130003249/http://www.theverge.com/2015/6/23/8834059/apple-ios-9-can-temporarily-delete-apps-before-updates|archive-date=January 30, 2017}} iOS 9 also features "app thinning" functionality, whereby only the necessary assets needed to run apps on each individual device is downloaded rather than the entire app, potentially saving space.{{cite web|url=http://www.trustedreviews.com/news/apple-fixes-flaw-that-prevented-ios-9-app-thinning|title=Apple fixes flaw that prevented iOS 9 app-thinning|last=Smith|first=Chris|date=October 6, 2015|website=TrustedReviews|access-date=February 1, 2017|url-status=dead|archive-url=https://web.archive.org/web/20160125204526/http://www.trustedreviews.com/news/apple-fixes-flaw-that-prevented-ios-9-app-thinning|archive-date=January 25, 2016}} For example, with the new app thinning technology, when a user downloads a new app onto their new iPhone 6S, the download would only include the images and data that are required on that device, so that no space is required for the images and data that would not be used on the device.

For the first time, iOS 9 adds a number of features to the iPad to improve productivity. These include Slide Over, Split Screen, and Picture in Picture, for enhanced multitasking, similar to the experience found on OS X El Capitan. Slide Over allows the user to pull in a second app with a swipe from the right edge of the display. This app takes up 1/3 of the screen and sticks to the right side of the screen, while interactivity within the full-screen app is disabled while left inactive in the background. The feature allows users to perform quick tasks and then dismiss the app again.{{cite web|url=https://www.cnet.com/how-to/how-to-use-the-ipads-new-slide-over-feature-in-ios-9/|title=How to use the iPad's new 'slide-over' feature in iOS 9|last=Cipriani|first=Jason|date=August 28, 2015|website=CNET|publisher=CBS Interactive|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20160814023017/http://www.cnet.com/how-to/how-to-use-the-ipads-new-slide-over-feature-in-ios-9/|archive-date=August 14, 2016}}{{cite web|url=http://www.macrumors.com/2015/09/16/ios-9-split-screen-multitasking-ipad/|title=Inside iOS 9: Split-Screen Multitasking for the iPad|last=Clover|first=Juli|date=September 16, 2015|website=MacRumors|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20161229060035/http://www.macrumors.com/2015/09/16/ios-9-split-screen-multitasking-ipad/|archive-date=December 29, 2016}}

If the user taps on the handle next to the Slide Over window or extends the window further towards the left of the screen, the user enters Split Screen, which allows them to interact with two apps simultaneously side-by-side in a 50/50 split. Users can also switch to another app in either Slide Over mode or Split Screen view by pulling down on the handle on top of either app and selecting another app from the list to replace the existing one.{{cite web|url=https://www.cnet.com/how-to/get-to-know-the-ipads-new-split-view-feature-in-ios-9/|title=Get to know the iPad's new 'split-view' feature in iOS 9|last=Cipriani|first=Jason|date=September 11, 2015|website=CNET|publisher=CBS Interactive|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20170222021122/https://www.cnet.com/how-to/get-to-know-the-ipads-new-split-view-feature-in-ios-9/|archive-date=February 22, 2017}}

Night Shift is a display mode introduced in iOS 9.3. The mode shifts the colors of the device's display to be warmer, similar to F.lux, a popular program for Microsoft Windows and Apple macOS computers.{{cite web|url=http://www.macrumors.com/2016/01/11/apple-ios-9-3-night-shift/|title=Apple Introduces New 'Night Shift' Feature in iOS 9.3|last=Clover|first=Juli|date=January 11, 2016|website=MacRumors|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20161028063833/http://www.macrumors.com/2016/01/11/apple-ios-9-3-night-shift/|archive-date=October 28, 2016}}{{cite web|url=http://appleinsider.com/articles/16/03/22/why-apples-night-shift-in-ios-93-will-help-you-get-a-better-nights-sleep|title=Why Apple's Night Shift in iOS 9.3 will help you get a better night's sleep|date=March 22, 2016|website=AppleInsider|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20161225221935/http://appleinsider.com/articles/16/03/22/why-apples-night-shift-in-ios-93-will-help-you-get-a-better-nights-sleep|archive-date=December 25, 2016}} When enabled, it uses the device's clock and geographic location to determine when to turn the feature on or off. Optionally, the user can set a manual schedule, or not have a schedule at all. For ease of access, there is a new Night Shift toggle in the Control Center. The settings for Night Shift are located under "Display and Brightness" in the Settings app, and on top of enabling the feature and setting a schedule, the user can also set the warmth of the display.{{cite web|url=http://www.macrumors.com/how-to/use-ios-9-3-night-shift-mode/|title=How to Use Night Shift Mode in iOS 9.3|last=Clover|first=Juli|date=January 14, 2016|website=MacRumors|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20161120081201/http://www.macrumors.com/how-to/use-ios-9-3-night-shift-mode/|archive-date=November 20, 2016}}

Despite being introduced in iOS 9.3 in March 2016, it wasn't possible to use Night Shift and Low Power Mode simultaneously until the release of iOS 9.3.2 two months later.{{cite web |first=Juli |last=Clover |title=Apple Releases iOS 9.3.2 With Support for Simultaneous Night Shift/Low Power Mode Usage |url=http://www.macrumors.com/2016/05/16/apple-releases-ios-9-3-2/ |website=MacRumors |date=May 16, 2016 |access-date=December 20, 2016 |url-status=live |archive-url=https://web.archive.org/web/20161117213604/http://www.macrumors.com/2016/05/16/apple-releases-ios-9-3-2/ |archive-date=November 17, 2016 }} Night Shift requires a 64-bit processor only found in the Apple A7 or newer chips, which means older iOS devices, including the iPhone 4s, iPhone 5, iPhone 5c, iPad 2, iPad 3, iPad 4, first-generation iPad Mini, and 5th generation iPod Touch, do not receive Night Shift mode.

iOS 9 includes performance and speed improvements thanks to the expanded use of the Metal API. Metal was introduced in iOS 8 and was previously limited to game developers. In iOS 9, the use of Metal is expanded to let it handle many of the core user interface elements and graphics.{{cite web|url=http://www.ibtimes.co.uk/9-reasons-why-ios-9-will-make-your-old-iphone-feel-like-new-1519281|title=9 reasons why iOS 9 will make your old iPhone feel like new|last=McClelland|first=David|date=September 10, 2015|website=International Business Times|publisher=IBT Media|access-date=December 20, 2016|url-status=live|archive-url=https://web.archive.org/web/20170420090946/http://www.ibtimes.co.uk/9-reasons-why-ios-9-will-make-your-old-iphone-feel-like-new-1519281|archive-date=April 20, 2017}}

Intelligence is one of the main features in iOS 9, consisting of the newly integrated Siri and Search (previously known as Spotlight), as well as "proactivity" throughout the operating system. iOS is now more aware of contextual information (such as time and location), and proactively provides the user with what they may need in advance to save them time and effort. When typing, Search has also been improved to display instant answers in an at-a-glance, widget-like format, similar to that provided in the Siri interface. Search can display current weather, sports scores, news, and more. The Search screen with proactive suggestions can be accessed either by pulling down the notifications window, in the Safari web browser through the search bar, and to the left on the home screen.{{cite web |first=Andrew |last=Cunningham |title=iOS 9, thoroughly reviewed |url=https://arstechnica.com/apple/2015/09/ios-9-thoroughly-reviewed/5/#h5 |website=Ars Technica |publisher=Condé Nast |date=September 16, 2015 |access-date=December 20, 2016 |url-status=live |archive-url=https://web.archive.org/web/20161221000039/http://arstechnica.com/apple/2015/09/ios-9-thoroughly-reviewed/5/#h5 |archive-date=December 21, 2016 }}

The intelligence also extends into apps. For instance, in Mail, events can be automatically added to Calendar if details are found in the message content, and likely additional recipients are suggested during message composition.

iOS 9 received mostly positive reviews. Dan Seifert of The Verge praised the improvements in Proactivity and Siri, highlighting how the notification drop-down contains most, if not all, the information the user needs.

In February 2016, news outlets reported that users who updated to iOS 9 on a particular device that had components repaired by a third-party (notably the Touch ID fingerprint recognition sensor) rendered their phone unusable.

We protect fingerprint data using a secure enclave, which is uniquely paired to the Touch ID sensor. When iPhone is serviced by an authorised Apple service provider or Apple retail store for changes that affect the Touch ID sensor, the pairing is re-validated. ... This check ensures the device and the iOS features related to Touch ID remain secure. Without this unique pairing, a malicious Touch ID sensor could be substituted, thereby gaining access to the secure enclave. When iOS detects that the pairing fails, Touch ID, including Apple Pay, is disabled so the device remains secure.

Apple released a new version of iOS 9.2.1 later in February to fix the issue.{{cite web |first=Matthew |last=Panzarino |title=Apple Apologizes And Updates iOS To Restore iPhones Disabled By Error 53 |url=https://techcrunch.com/2016/02/18/apple-apologizes-and-updates-ios-to-restore-iphones-disabled-by-error-53/ |website=TechCrunch |publisher=AOL |date=February 28, 2016 |access-date=December 20, 2016 |url-status=live |archive-url=https://web.archive.org/web/20161223144111/https://techcrunch.com/2016/02/18/apple-apologizes-and-updates-ios-to-restore-iphones-disabled-by-error-53/ |archive-date=December 23, 2016 }}

{{Main|Pegasus (spyware)}}

The release of iOS 9.3.5 in August 2016 fixed three critical security vulnerabilities. The vulnerabilities could be exploited to silently enable a jailbreak and allow the malicious installation of a spyware called "Pegasus". Pegasus could intercept and read text messages, emails, track calls, trace phone location, activate the microphone, and gather information from apps, including (but not limited to) iMessage, Gmail, Viber, Facebook, WhatsApp, Telegram, and Skype.{{cite web |first=Thomas |last=Fox-Brewster |title=Everything We Know About NSO Group: The Professional Spies Who Hacked iPhones With A Single Text |url=https://www.forbes.com/sites/thomasbrewster/2016/08/25/everything-we-know-about-nso-group-the-professional-spies-who-hacked-iphones-with-a-single-text/ |website=Forbes |date=August 25, 2016 |access-date=December 21, 2016 |url-status=live |archive-url=https://web.archive.org/web/20170110135726/http://www.forbes.com/sites/thomasbrewster/2016/08/25/everything-we-know-about-nso-group-the-professional-spies-who-hacked-iphones-with-a-single-text/ |archive-date=January 10, 2017 }}

The discovery of the vulnerabilities dated 10 days before the 9.3.5 update was released. Arab human rights defender Ahmed Mansoor received a suspicious text message with a link and sent it to Citizen Lab. An investigation ensued with collaboration from Lookout that revealed that if Mansoor clicked the link, it would have jailbroken his phone and implanted it with the spyware. Citizen Lab linked the attack to an Israeli surveillance company known as NSO Group that sells Pegasus to governments for "lawful interception."{{cite journal |first1=Bill |last1=Marczak |first2=John |last2=Scott-Railton |title=The Million Dollar Dissident: NSO Group's iPhone Zero-Days used against a UAE Human Rights Defender |url=https://citizenlab.org/2016/08/million-dollar-dissident-iphone-zero-day-nso-group-uae/ |website=Citizen Lab |date=August 24, 2016 |access-date=December 21, 2016 |url-status=live |archive-url=https://web.archive.org/web/20161217014412/https://citizenlab.org/2016/08/million-dollar-dissident-iphone-zero-day-nso-group-uae/ |archive-date=December 17, 2016 }}{{Cite web|url=https://www.vice.com/en_us/article/3da5qj/government-hackers-iphone-hacking-jailbreak-nso-group|title=Government Hackers Caught Using Unprecedented iPhone Spy Tool|last=Franceschi-Bicchierai|first=Lorenzo|date=August 25, 2016|website=Vice|language=en-US|access-date=June 4, 2019|archive-date=September 3, 2020|archive-url=https://web.archive.org/web/20200903100656/https://www.vice.com/en_us/article/3da5qj/government-hackers-iphone-hacking-jailbreak-nso-group|url-status=live}}

Regarding how widespread the issue was, Lookout explained in a blog post: "We believe that this spyware has been in the wild for a significant amount of time based on some of the indicators within the code" and pointed out that the code shows signs of a "kernel mapping table that has values all the way back to iOS 7."{{cite web |title=Sophisticated, persistent mobile attack against high-value targets on iOS |url=https://blog.lookout.com/blog/2016/08/25/trident-pegasus/ |website=Lookout |date=August 25, 2016 |access-date=December 21, 2016 |url-status=live |archive-url=https://web.archive.org/web/20161217041121/https://blog.lookout.com/blog/2016/08/25/trident-pegasus/ |archive-date=December 17, 2016 }}

In July 2017, information on a critical Wi-Fi security vulnerability affecting 1 billion iOS and Android devices was published. The issue, named "Broadpwn", allows an attacker to remotely take control of nearby vulnerable devices and turn affected devices into "rogue access points", further spreading the infection to other nearby devices.{{cite web |first=Andy |last=Greenberg |title=How a bug in an obscure chip exposed a billion smartphones to hackers |url=https://www.wired.com/story/broadpwn-wi-fi-vulnerability-ios-android/ |website=Wired |publisher=Condé Nast |date=July 27, 2017 |access-date=October 12, 2017 |url-status=live |archive-url=https://web.archive.org/web/20170918234540/https://www.wired.com/story/broadpwn-wi-fi-vulnerability-ios-android |archive-date=September 18, 2017 }} Apple released a security patch for the issue as part of its iOS 10.3.3 update,{{cite web |first=Roger |last=Fingas |title=Apple's iOS 10.3.3 update protects against 'Broadpwn' Wi-Fi exploit |url=http://appleinsider.com/articles/17/07/20/apples-ios-1033-update-protects-against-broadpwn-wi-fi-exploit |website=AppleInsider |date=July 20, 2017 |access-date=October 12, 2017 |url-status=live |archive-url=https://web.archive.org/web/20171013013705/http://appleinsider.com/articles/17/07/20/apples-ios-1033-update-protects-against-broadpwn-wi-fi-exploit |archive-date=October 13, 2017 }} though older devices running iOS 9, including the iPad 2, 3rd generation iPad, iPhone 4s, the first-generation iPad Mini, and the 5th generation iPod Touch were left without an available update, causing concerns over the safety of the iPad 2, the 3rd generation iPad, and the first-generation iPad Mini in schools.{{cite web |first=Andrew |last=Walters |title=Thousands of iPad 2 tablets in schools just became ticking timebombs |url=https://www.sirius.co.nz/thousands-of-ipad-2-tablets-are-ticking-timebombs/ |publisher=Sirius Information Services [New Zealand] |date=August 1, 2017 |url-status=dead |archive-url=https://web.archive.org/web/20190119182158/https://www.sirius.co.nz/thousands-of-ipad-2-tablets-are-ticking-timebombs/ |archive-date=January 19, 2019}}

On December 22, 2015, Apple faced a class-action lawsuit for crippling the iPhone 4s with the iOS 9 update, with some people even going so far as to say that iOS 9 rendered their devices unusable.{{Cite web|url=https://www.techtimes.com/articles/120915/20160103/apple-facing-lawsuit-for-allegedly-forcing-people-to-buy-newer-models-by-slowing-down-iphone-4s-with-ios-9.htm|title=Apple Facing Lawsuit For Allegedly Forcing People To Buy Newer Models By Slowing Down iPhone 4s with iOS 9|website=TechTimes|access-date=April 14, 2020|archive-date=November 8, 2020|archive-url=https://web.archive.org/web/20201108114627/http://www.techtimes.com/articles/120915/20160103/apple-facing-lawsuit-for-allegedly-forcing-people-to-buy-newer-models-by-slowing-down-iphone-4s-with-ios-9.htm|url-status=live}}{{Cite web|url=https://www.cultofmac.com/404282/5-million-lawsuit-asks-did-ios-9-cripple-iphone-4s-devices/|title=$5 million lawsuit asks: Did iOS 9 cripple iPhone 4s devices?|website=Cult Of Mac|date=December 30, 2015 |access-date=April 14, 2020|archive-date=November 8, 2020|archive-url=https://web.archive.org/web/20201108142001/https://www.cultofmac.com/404282/5-million-lawsuit-asks-did-ios-9-cripple-iphone-4s-devices/|url-status=live}} The 4s only had 512MB of RAM,{{Cite web|url=https://www.gsmarena.com/apple_iphone_4s-4212.php|title=Apple iPhone 4S|date=April 14, 2020|website=GSMArena|access-date=April 14, 2020|archive-date=March 29, 2020|archive-url=https://web.archive.org/web/20200329215441/https://www.gsmarena.com/apple_iphone_4s-4212.php|url-status=live}} so it could not handle the iOS 9 update.

Around early 2018, some users who still had devices running iOS 9 with the A9 chip reported being prompted by an "Activation Error" screen that occurred at any random time. Attempting to get out of this error screen would only send the user back to the said screen, unless they restored their device to the latest iOS version in iTunes (which also meant data loss was possible if the device had content in it, as restoring the device wipes everything from it). This bug still persists as of the present day for certain users currently running iOS 9 on their A9 devices, and its cause is currently unknown.{{Cite web|url=https://www.youtube.com/watch?v=UxaCUugPoRY|title=Older iPhones Bricked For Being Too Outdated - Locking Users From Their Data|access-date=January 9, 2023|website=YouTube|archive-date=January 10, 2023|archive-url=https://web.archive.org/web/20230110090423/https://www.youtube.com/watch?v=UxaCUugPoRY|url-status=live}} As of May 2025, Apple has made no public comment regarding the issue.
