iOS 16.4 is here: new features, supported iPhones and all you need to know

Apple unveiled iOS 16 – the latest operating system for iPhone and the successor to iOS 15 – at WWDC 2022 back in June last year, but the update didn’t actually arrive until September 12, where it coincided with the release of the iPhone 14 line. 

Now out in the wild as iOS 16.4 in 2023 – having been through four subsequent updates since its September debut – the software release brings improvements to many apps, with lock screen widgets, better privacy features, improved phone calls and new fonts, colors and emojis chief among the newly arrived features.

iOS 16.4 release date

Apple confirmed iOS 16’s September 12 release date at its ‘Far Out’ event on September 7, 2022, where it also announced the iPhone 14, Apple Watch Series 8, Apple Watch Ultra and AirPods Pro 2. 

iOS 16.4 became available to download on March 27, 2023, following three separate iterative updates to the new OS. 

iOS 16 Features

There are all sorts of new and improved features on iOS 16, and we’ve detailed the key ones below.

Customizable lock screens

With iOS 16, you’re able to customize your lock screen by tapping in any area to change the text font and colors.

Complications (which are essentially widgets) can also be enabled here, a feature lifted from the Apple Watch. You’re able to add three of these to your lock screen, while the Now Playing screen has been moved towards the bottom for easier access with your thumb.

You’re not limited to just one lock screen, either. Similar to creating a watch face on your Apple Watch, you can swipe between different lock screens, so you can have access to different widgets based on your needs.

Focus

Focus mode also got some updates, many of which tie into the lock screen, as the lock screen that’s shown can automatically be switched based on the Focus profile you have.

For example, a ‘Meeting’ focus profile could make your lock screen change wallpaper and offer a row of widgets showing details of that event.

You can also use ‘Focus Filters’ to block out tabs in Safari, accounts in Mail, events in Calendar, and more, to help you manage your workflow. We’ve made a comprehensive guide of how to set up Do Not Disturb and Focus mode to help get you started.

Notifications

Notifications have also been improved with ‘Live Activities’, which are essentially pinned widget-like notifications that allow you to check the score of a game, track the progress of a food delivery, and more.

Notifications have a new design, too, aimed at making them visually pop, and they also feature new animations, rolling in from the bottom of the lock screen so they’re easy to see at a glance while staying out of the way.

And you can choose to view notifications in an expanded list view, a stacked view, or a hidden view.

Messages

Apple has added several new features to Messages. ‘Undo send’ has arrived for one, allowing you to delete a message for up to 15 minutes after you’ve sent it – for example, if you realize you’ve sent it to the wrong person. Similarly, you can also edit messages in the first 15 minutes. Note though that this only works for iPhone to iPhone messages.

SharePlay is also now available on the app, so you can play a movie in Disney Plus for example, and share it with someone via Messages.

Dictation has also been improved, as it now lets users move fluidly between voice and touch inputs, so you can type to add text or move the cursor without having to stop Dictation.

Clearer cellular phone calls

Perhaps the biggest quality-of-life upgrade to come with iOS 16.4 was Voice Isolation for cellular calls, which helps reduce ambient noise during your phone calls.

This feature was already available on apps like WhatsApp or FaceTime, which you’ve probably noticed tend to sound better than cellular calls. But with iOS 16.4, it finally came to cellular calls – to access it, you’ll just need to swipe down the top-right of the screen (to access the Control Center), tapping Mic Mode, then Voice Isolation.

Apple has also confirmed that Voice Isolation is compatible with every iPhone model released alongside or after the iPhone SE (2020), which means most of the best iPhones benefit, too.

Accessibility

Hinted at by Apple in May, 2022, several new accessibility features have since arrived on iOS 16, such as door detection, which helps you locate doors, read signs around them, and get instructions for opening them.

There’s also the option to view live captions in a FaceTime call, control your Apple Watch from your iPhone, hang up phone calls with Siri, and more.

Live text has seen improvements as well – you can copy and paste text in video, alongside being able to copy and translate text.

An improved Podcasts app

If you mainly feed your podcast habit in Apple’s default Podcasts app rather than third-party ones, you’ll see several small improvements to the overall experience in iOS 16.4.

Firstly, it’s now easier to find shows that are part of wider channels or networks. When you follow a show that’s part of a channel (for example, a network that produces multiple shows, like Bloomberg or the BBC), you’re able to see it in a new dedicated Channels section in your podcast Library.

This is handy, given that many podcasts are now part of wider networks that produce several shows around similar themes. When you tap on a channel, you’ll see the shows you follow at the top, plus any subscription options that are available for that network.

Wallet

Wallet has seen privacy improvements, with in-app ID verification being enabled for third-party apps.

Tap to pay on iPhone also arrived with iOS 16, removing the need for any point of sale terminals. Plus, you can view receipts and track orders directly from Wallet.

There’s also Apple Pay Later, which splits purchases into four interest-free payments spread over six weeks, and Order Tracking, which lets you see the latest information on your Apple Pay orders.

Apple Books animations

This one’s strictly for fans of the Apple Books app, so a little niche. But if that’s you, Apple brought back a strangely satisfying animation to the app with iOS 16.4 – the ‘curl’ page-turn effect.

For some reason, this animation – which mimics a page being turned over – was removed in iOS 16 as it first appeared. But if you’ve missed seeing your digital pages turning in the Books app, you’ll be happy to see that effect return when you upgrade to iOS 16.4.

Maps

Maps now finally enables you to store recent trips in the app, and you can send them from a Mac or iPad device.

You can also add multiple stops on a route, and while on a journey you can ask Siri to add another destination, hands-free, in case another errand pops up, while ‘Look Around’, Apple’s take on Google Street View, is being opened up to third-party apps.

Plus, you can see transit fares, and – without leaving Maps – you can add transit cards to Wallet, replenish your card, and see low balances.

Sports

iOS 16 saw a big push on sports, with Apple News getting a new My Sports section to let you view schedules, standings and scores for your favorite teams. 

Live updates for sporting events can also be added to the lock screen, so if you’re not able to tune in you’ll still be kept up to date with the score.

Family Sharing

Apple’s Family Sharing feature enables you and your family to share an account, for example to view photos and videos, and so that parents can approve purchases made by minors.

In iOS 16, it’s easier for parents to set age-appropriate restrictions on content, and parents or guardians can respond to Screen Time requests in Messages.

A quick start feature for iPad lest you sync settings that you’ve configured on your iPhone to an iPad simply by moving your phone close to the tablet, and there’s also a Family Checklist feature, making it easier for you to be confident that all of the content on an iPhone is secure and child-safe.

The ability to share photos and videos over iCloud was widely requested, and iCloud Shared Photo Library now allows up to six people to share a library. Users can send photos to the Shared Library using a new toggle in the Camera app, and receive intelligent suggestions to share photos that include other users of a shared library.

Safety Check

A new privacy tool called Safety Check has been introduced to help those at risk from violence or harassment by partners.

Users can quickly revoke all access to Messages and other accounts that they’ve granted to a partner, and an emergency reset feature helps users to easily sign out of iCloud on all their other devices, reset privacy permissions, and limit messaging to just the device in their hand. Users can also stop sharing their location with this tool.

It also lets you generally check and manage which people and apps you’ve given access to your information.

Home App is redesigned

In conjunction with the new Matter smart home standard, the Home app was redesigned to make it easier to manage your smart appliances and rooms.

You’re now able to see all your rooms in a single view, alongside categories for lights, climate, security and more. You can tap on a category to see more detailed status information, and view up to four security cameras at once.

You can also add smart home widgets to the lock screen, allowing you to view the status of your home at a glance, and quickly access smart home controls.

Spatial Audio

You can use your iPhone’s TrueDepth Camera to create a personal Spatial Audio profile for your AirPods Pro or AirPods Max, for what Apple calls “an even more precise and immersive listening experience.”

Fitness

Apple’s Fitness app is now available to all iPhone users, even if they don’t have an Apple Watch to help them track their fitness. The app will use the motion sensors of your iPhone along with step and distance tracking, and workouts from third-party apps, to help you achieve your daily Move goal and estimate your calorie burn.
