Can my iPhone or iPad get iOS 9? Full list of iOS 9 compatible devices.

Can my iPad or iPhone run iOS 9? Which models are compatible with iOS 9? And can/should I upgrade my iPhone 4s to iOS 9?

Some Apple fans will be crushed to learn that their devices won't be able to run the iOS 8 operating system. But there's good news for iPad 2 owners. Here's the official list of iPhones, iPods and iPads that made the cut, and can run iOS 8 (information from Apple's website):

iPhone 4s, iPhone 5, iPhone 5c, iPhone 5s, iPhone 6 and iPhone 6 PlusiPad 2, iPad 3, iPad 4, iPad Air ( presumably the iPad 6 and/or iPad Pro when and if they launch)iPad mini 1 and iPad mini 2 with Retina display (...and the iPad mini 3 when/if it launches)iPod touch 5G

Which iOS 8 features will older iPads and iPhones miss out on?

Mostly the Continuity features. They're available on the iPhone 5 or later, iPad 4 and later, both iPad minis and the 5th-gen iPod touch. The iPhone 4, iPad 2 and iPad 3 miss out, in other words.

A potentially bigger issue is how well your older device's processor will be able to handle the increased demands that iOS 8 will put on it.

What? Will my iPhone or iPad get slower if I upgrade to iOS 8?

It might. Lower-end iPads and iPhones may struggle with performance issues when upgrading from iOS 7 to iOS 8. This was a cause of considerable frustration last year — the iPhone 4 was the oldest iPhone that could run iOS 7, and it ran noticeably slowly compared to iOS 6. (Apple addressed this in iOS 7.1, but only partially.)

We're hearing a fair few reports that iOS 8 slows down the iPhone 4s to a noticeable degree, including sometime Macworld contributor Orestis Bastounis:

have downgraded my 4S back to iOS 7. Way too slow. Currently looking down back of sofa for 1p coins to put towards a 6.

Ars Technica's testing concluded that an iPhone 4s took almost 50 percent longer to complete some tasks on iOS 8 as it did on iOS 7, and Gottabemobile agreed: "Speed and fluidity in iOS 8 has clearly taken a hit... There's an overall sluggishness and it makes using the iPhone 4s a chore. Animations are slow, transitions are slow, apps open up slow, it's a mess."

Should I update my iPhone 4 to iOS 8?

We'd recommend that you don't, unless you're so desperate for one of the new features (and not Continuity, which you won't get) that you're willing to take a speed hit.

What about the iPad 2?

Again, it's probably not worth the negatives. Indeed, some iPad 3 owners are reporting slowdowns. Your mileage may vary, of course.
