Which iPads and iPhones can run iOS 8?
When a new version iOS is launched, promising exciting new features and a polished (or entirely revamped) interface, many Apple fans on slightly older devices are forced to make a hard decision: abandon their cherished old iPhone or iPad - which may get an incomplete feature set, run slower or fail to run the new iOS at all - or miss out on the new iOS update. Well, iOS 8 is here, along with the iPhone 6 and iPhone 6 Plus, and it's jampacked with great new features. Obviously the iPhone 6 and 6 Plus run iOS 8, but can your iPhone or iPad run iOS 8? And has the time come to upgrade your hardware in order to make the software upgrade?
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 Plus
- iPad 2, iPad 3, iPad 4, iPad Air (...plus 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.— Orestis Bastounis (@MrBastounis) September 18, 2014
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.
My iPhone or iPad isn't on the list of compatible devices. What happens to older models? What should I do now?
If your iPad or iPhone isn't on the list above you won't be able to download any further updates to iOS (with the exception of security patches). This isn't the end of the world, and your device will continue to work and run as safely as before - you just won't get to enjoy the new features in iOS 8 (and iOS 9, and so on). Some apps specify a minimum iOS version, but you will probably find your ageing device's processing power limits your choice of apps much more than the fact that you're still on iOS 7, at least for a while.
Now may be the time to upgrade your device. But if you don't want to, or can't afford an upgrade, you can quite happily continue to run your iPhone 4, say, or original iPad - assuming you are satisfied with their speed. Don't feel pushed into an upgrade just because your device is no longer supported for iOS updates.
Which iPads and iPhones ran iOS 7 and previous versions of iOS?
If you're interested in iOS history, here's a list of the devices that supported previous versions of iOS. We used these to observe the trends and make our predictions before the official iOS 8 announcements.
- iPhone OS 3: iPhone 1 and later; iPad 1 and later; iPod touch 1G and later
- iOS 4: iPhone 3G and later; iPad 1 and later; iPod touch 2G and later
- iOS 5: iPhone 3GS and later; iPad 1 and later; iPod touch 3G and later
- iOS 6: iPhone 3GS and later; iPad 2 and later; iPad mini 1 and later; iPod touch 4G and later
- iOS 7: iPhone 4 and later; iPad 2 and later; iPad mini 1 and later; iPod touch 5G
Which Apple devices will support iOS 8: our original predictions, and how we did
As we can see above, iPod touch support has tended to move up at the rate of one generation of iPod per version of iOS; at this rate we'd expect iOS 8 to only be available on a speculative sixth-generation iPod touch. But such a device doesn’t exist yet. One could conceivably be unveiled alongside iOS 8, but we think it’s more likely that iOS 8 will be supported by the 5th-gen iPod touch only. That's an easy one to start with. Update: we got this right - but it was pretty obvious!
iPad support has dropped off more slowly: the iPad 1 was launched while iPhone OS 3 was still (just) the current software, yet was able to run iOS 5 two versions later.
The iPad 2 has been the bottom rung for both iOS 6 and iOS 7, and may well be removed from the list of iOS 8-compatible hardware (especially as Apple no longer sells this tablet). Our prediction is that iOS 8 will be compatible with the iPad 3 and later. Update: nope - the iPad 2 survives.
It's possible that the iPad mini 1 won't be able to run iOS 8 but, with the device still on sale and only two possible mini models for buyers to choose from, we think this is unlikely. Update: correct.
iPhones have been moved downwards on the iOS ladder at the rate of one model every one to two versions of iOS. Which suggests that the iPhone 4 might survive, and it might not (it's only been on the bottom rung for a single version). But given the performance problems that have beset iPhone 4 models running iOS 7 (slightly alleviated, admittedly, by iOS 7.1), we think it will almost certainly be removed from iOS 8 compatibility. Our prediction is iPhone 4s and later. Update: correct. Three out of four, then.
More coverage of WWDC 2014
At WWDC 2014, Apple unveiled iOS 8 and OS X Yosemite. Read all about the event here: WWDC 2014 as it happened. We also have an OS X Yosemite review and an iOS 8 review (each based on preview beta versions of the software; they will be updated when the final versions launch).
Want to know what happened at WWDC the year before? At WWDC 2013, Apple unveiled OS X 10.9 Mavericks and iOS 7, both of which were released as beta versions after the event, as well as the new Mac Pro, a new MacBook Air, iTunes Radio, and iWork for iCloud.
