Apple unveiled four big operating system updates at WWDC on 4 June 2018, and the biggest of all was iOS 12, the new OS for iPhone and iPad.

iOS 12 will be released to the public in September, and beta testing versions will be available sooner than that. But is it any good, and – given how difficult it will be to go back to iOS 11 – should iPhone and iPad owners make the upgrade?

In this article we compare the interface, features, performance and ease of use of iOS 11 and 12, to help you decide if upgrading is the right decision for you.

Performance

Let’s start with the headline upgrade: speed. iPads and iPhones on iOS 12 should run faster and more responsively than the same devices on iOS 11 and below, because processor performance is ramped up when it’s needed then ramped down afterwards to preserve battery life.

This is particularly true of older devices, Apple says: on the iPhone 6 Plus, for instance, apps load up to 40% faster in iOS 12, the keyboard comes up 50% faster and sliding to take a photo is up to 70% faster. And even in newer devices you should see the share sheet appearing twice as fast and apps loading twice as fast too.

Bear in mind that these are Apple’s figures, and we will need to test this all out for ourselves. But it sounds great in theory. (Also take a look at How to speed up a slow iPhone for more tips.)

Augmented reality

If you’re into AR, the iOS 12 update is for you.

Thanks to a new file format, called USDZ, developers and designers will be able to create AR experiences and share them easily. The News app will start featuring AR content, and Apple expects lots of websites to follow suit – the Fender website offering configuration options then letting you see your guitar in the real world, for example.

And the update ARKit 2 offers clever measurement tools made possible by ARKit 2. You can view a real-world object using your iPhone’s camera, tap two points on a table, for example, and see a measurement for its length and width.

Finally, ARKit will allow shared experiences. In AR games, for example, multiple players and observers on separate iPads will be able to observe the gameplay from their respective viewpoints.

Photos

Photos gets smarter in iOS 12. iOS 11 Photos is already to handle object searches to a limited extent – you can search for cat or dog, for instance, although the latter turns up one photo of my toddler wearing a spotty jumper – but in iOS 12 there will be more categories and hopefully a higher success rate.

Your iPhone will also be proactive about suggesting people you should share your photos with, if you’ve attended a concert with them, for example. And if they’re on iOS 12 too, their iPhone will know to search for photos at the same event, and suggest sending them back.

Siri

Siri in iOS 11 is okay – Apple’s voice assistant is behind rivals such as Alexa, but always improving – but a new feature in iOS 12 may win over some converts to its capabilities.

Siri shortcuts are custom voice-triggered actions. In some cases these will be created by third-party apps, whose developers will add an ‘Add to Siri’ icon which then creates a shortcut for a specific feature; in others the shortcut will be suggested by iOS itself when it thinks you need to turn on Do Not Disturb or ring your grandma, for instance. But it gets more powerful when you build your own shortcuts, which can include multiple steps and even multiple apps. Here’s how to make a Siri shortcut.

Digital wellbeing

By which we mean the raft of new tools and features in iOS 12 that are designed to combat device addiction (particularly for kids), improve work/life balance and reduce information overload.

Do Not Disturb, for instance, was already a handy mode in iOS 11 for shielding you from distracting notifications; a sub-mode called Do Not Disturb While Driving could even activate automatically when it thought you were in a car, although this was easily fooled by bus and train rides. iOS 12 takes this all further, adding another submode called Do Not Disturb During Bedtime and the ability to set endings for DND by time or location.

Notifications, which most of us have found overwhelming at one time, are in iOS 12 grouped together by app, topic and thread, and therefore easier to edit or clear en masse. And it’s easier to adjust your notification settings – press into a notification and you’ll be able to decide whether to turn them off from that source entirely, or simply tune the circumstances under which it notifies you. Siri will make suggestions about notifications to turn off because you’re not using them.

Finally, and perhaps most significantly, a new feature called Screen Time allows you to monitor your device usage by app, app category, time of day or night and much more, and to set limits on your (or your child’s) use of particular apps or types of content.

Animoji

Animoji are animated emoji that match your own facial expressions. They were brought in with the iPhone X and are dependent on its sophisticated front-facing sensor array.

If you’ve got an iPhone X, upgrading to iOS 12 will seem like a no-brainer, because it features a major step forward for Animoji. Rather than being tied to the pre-defined set of Animoji, iOS 12 lets you create your own, called Memoji.

Of course, you can still use the premade Animoji, and these are now bolstered by the addition of four newbies: tiger, koala, ghost and T-Rex.

FaceTime

iOS 12 adds a long-requested features to FaceTime: group video calls. You’ll be able to video chat with up to 31 other people at the same time.

It’s an exciting and fun new option (and slightly shocking it’s taken this time to arrive, really) but be warned that the group chat interface seems to us like a bit of a dog’s dinner: user tiles move around and change in size when users speak, and the whole thing is a bit ugly and confusing. Hopefully we’ll get used to it, or Apple will tweak the interface.

Miscellaneous Apple app updates

These are less thrilling than the above changes, but Apple also announced smaller tweaks and changes to a number of its own apps in iOS 12.

News, Stocks, Voice Memos and iBooks all get redesigns (and the latter a name change, to Apple Books). Stocks now includes headlines from the News app, and is available on iPad. And CarPlay now supports third-party navigation apps.

Compatible devices

iOS 11 and 12 are compatible with exactly the same set of iPads and iPhones:

  • iPad Pro (10.5), iPad Pro (12.9, 2017)
  • iPad 2017, iPad 2018
  • iPad mini 2, iPad mini 3, iPad mini 4
  • iPhone 5s, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, iPhone X
  • iPod touch (sixth generation)

This isn’t the first time Apple has kept the same list of devices from one version of iOS to the next: iOS 9, for instance, supported all iOS 8-compatible iPhones and iPads. But we’re normally sceptical about whether older devices can actually cope with the greater processor demands presented by new software.

This time, however, might be different. Apple’s emphasis on iOS 12’s performance improvements over iOS 11 suggest that older iDevices could actually see a speed boost by upgrading, although we’d like to see the for ourselves.

You can read more about this subject in our dedicated article about iPhone and iPad iOS compatibility.

Release date/availability

iOS 11 is out now. iOS 12 will come out in the autumn. But it’s possible to test it out before then.

As of 11 June 2018, the current version of iOS is 11.4, so anyone choosing to update their iPhone or iPad will get that (assuming the device is compatible).

At present iOS 12 is available only as a pre-release beta for software developers, but a public beta will be made available later in June. (Here’s how to install either sort of iOS 12 beta.) The public launch of iOS 12 will happen in the autumn – probably in September.

OUR VERDICT

iOS updates tend to be accumulative rather than transformative – adding features on top of the existing set, rather than changing everything – and iOS 12 is no exception.

Animoji fans, for instance, will get the chance to make their own Memoji, or use the four new Animoji, but the ones they used to love in iOS 11 are still there. Likewise iOS 12’s group FaceTime offering (ugly interface and all) doesn’t affect your ability to enjoy standard FaceTime, and Siri shortcuts and app limits are optional features that needn’t affect your experience if you’re not interested. And the interface hasn’t been radically altered (as it was in iOS 7, for example) so there won’t be too much getting used to things being different.

When you add in the promised speed boosts on older devices and the fact that all iOS 11-compatible iPads and iPhones will be able to run iOS 12, there really aren’t any reasons not to make the upgrade from iOS 11 to iOS 12. Sure, it will be profoundly difficult to go back to iOS 11 once you’ve upgraded, but we can’t think why you’d want to.

And as already mentioned above, there’s plenty of good stuff in the new update. Group FaceTime is long overdue but gratefully received, Memoji are a significant step forward for Animoji, shortcuts make Siri far more powerful, Screen Time and the other related features are an admirable step towards a healthier attitude to technology and device addiction. And everyone loves a speed boost.

In other words, we would wholeheartedly recommend that you can upgrade from iOS 11 to iOS 12 when the latter launches to the public in the autumn. You may like to try it out in beta before then, but bear in mind that this will be unfinished software and may brick your device – so install it on a secondary iPhone or iPad rather than one you depend on for work.
