We already know that some of the new iOS 11 features will not come to all of these devices.
With the upcoming release of iOS 11, many apps and three older devices will be getting the axe, which includes 2012's iPhone 5 and fourth-gen iPad, and 2013's very popular iPhone 5C.
Apple has announced new features for watchOS 4, including major updates coming to Workouts, Activity, Music, all-new watch faces, and "GymKit", which provides a seamless connection between Apple Watch and gym equipment. However, it is worth pointing out that iOS 9 had a similar feature back in 2015 - although that was only for temporarily deleting apps while upgrading to a new operating system.
The new iPad Pro costs $649 and will begin shipping next week. Both iPads will have feature Apple's True Tone display with wide color gamut comfort, alongside enhanced the camera system model upon the iPhone 7 camera. Apple devices will get this iOS 11 update in the last quarter of this year.
There is a new iMessage App Drawer so that it is easier to find the apps you want while you are in an iMessage conversation.
Particularly on iPad, the Files app could be perceived as bringing a bit of a Mac feel to Apple's handheld device while also addressing the needs of power users who have been calling out for such functionality. The tool, found in Settings General About Applications, lists installed apps that don't run in 64-bit mode, and warns: "The apps may slow down your iPhone and will not work with future version of iOS if they are not updated". This will also help keep large message thread storage in check without the need to delete threads all the time.
