If you have one of these iPhones or iPads, you won't get iOS 10
Apple announced the latest version of its operating system for the iPhone and iPad, iOS 10, at its annual Worldwide Developers Conference on Monday night.
The new software will allow Siri to access third-party apps, revamp iMessage to include features such as suggesting emoji and invisible ink messages, and let you delete the default apps you never use.
But if you have an iPhone or iPad of a certain vintage, forget about it. iOS 10 will be unavailable for the iPhone 4s, released in 2011; the iPad 2 and 3; the original iPad Mini and the fifth-generation iPod Touch.
These devices, which shared Apple’s A5 chip, were unexpectedly supported when Apple released iOS 9 last year, but the new software appears to be too demanding.
According to analytics company MixPanel, 3.41 percent of iPhone owners still use a 4s, 13.2 percent of iPad owners use an iPad 2, 15.9 percent use an iPad Mini and 8.3 percent use an iPad 3.
New versions of iOS are traditionally adopted much faster than the latest version of Android. More than four in five iOS devices run iOS 9, compared to one in 10 Android users on the latest software, Marshmallow.
But as the number of active iOS devices surpasses 1 billion, with many older models still being used, more end up running older operating systems.
Earlier this year, Apple released the iPhone SE, a smaller and cheaper iPhone with up-to-date innards intended to appeal to users who preferred the more pocket-size earlier models.
