7 top new iPhone 15 features

Four of the most exciting smartphones of 2023 have now arrived, with Apple having unveiled the iPhone 15, the iPhone 15 Plus, the iPhone 15 Pro, and the iPhone 15 Pro Max.

There’s a lot that’s changed this year, and you can head to our hands-on iPhone 15 review, iPhone 15 Pro review, and iPhone 15 Pro Max review to read our first impressions of those phones. But there are some clear highlights.

Below, you’ll find seven top new iPhone 15 features – these are in many cases things that Apple has already shouted about, and in all cases they rank among the main reasons to consider picking up a phone in the iPhone 15 line.

1. An iPhone finally has a periscope camera

Smartphone makers – other than Samsung – have been slow to adopt periscope cameras, which is a type of lens design that allows for longer distance optical zoom than a typical telephoto camera can manage.

As such, while Samsung has been offering a 10x optical zoom on its Galaxy Ultra phones for several generations, Apple has stuck with 3x. That is, until now.

While it still can’t match Samsung’s 10x optical zoom, the iPhone 15 Pro Max does at least have a 5x optical zoom camera, allowing you to zoom in much further than the 3x of its predecessor.

This will be ideal for taking photos of animals, high-up parts of buildings, and other things you can’t easily get close to.

2. USB-C instead of Lightning

Perhaps the most widely expected change for the iPhone 15 line was the move to USB-C. The European Union had dictated that device makers must make this change in 2024, so it was always likely that Apple would get ahead of the game this year. But while this might not have been Apple’s choice, USB-C is a top new feature.

This switch means that you’ll be able to use the same cable for most things since the best Android phones and the majority of other battery-powered gadgets use USB-C – as do recent iPads and MacBooks.

USB-C also potentially allows for far higher data transfer speeds, though only the iPhone 15 Pro and iPhone 15 Pro Max tap into this, with support for 10Gbps speeds.

3. All four models get a Dynamic Island

Arguably the headline feature of the iPhone 14 line was the Dynamic Island, which replaced the much-maligned notch with something genuinely useful and different. But this feature was originally exclusive to the Pro phones.

Now though, every iPhone 15 model has a Dynamic Island, so you don’t have to splash out on the iPhone 15 Pro or iPhone 15 Pro Max to get this exciting upgrade.

4. The Action button

One feature that’s exclusive to the iPhone 15 Pro models is an Action button, which sits where you’d previously have found the mute switch.

If you just want to mute and unmute your phone like with the previous switch this can do that. But it’s also customizable, so you can set it to trigger numerous other functions, such as turning the flashlight on and off, or launching the camera.

It’s a far more useful feature than the departing mute switch and it’s the sort of thing that you’ll wonder why it wasn’t added years ago – and why the standard models are left out.

5. A big main camera upgrade for the iPhone 15 and iPhone 15 Plus

While the headline camera upgrade for the iPhone 15 line is arguably the iPhone 15 Pro Max’s periscope camera, the iPhone 15 and iPhone 15 Plus also got a big upgrade, with a 48MP main sensor replacing the 12MP one of their predecessors.

This is capable of taking far higher resolution photos than the camera on the iPhone 14 and iPhone 14 Plus. Apple has claimed the photos taken with these new phones should be better in just about all scenarios, including for portraits and in low light environments.

6. A telephoto camera without a telephoto lens

Not only is the 48MP camera on the iPhone 15 and iPhone 15 Plus an upgrade in megapixels, it also doubles as a telephoto camera, as it can crop in to take optical quality 2x zoom shots at 12MP.

That means for the first time on a non-Pro iPhone you effectively have three rear cameras, including a telephoto. Of course, technically it’s still just two lenses, but this ups the versatility of the iPhone 15’s camera significantly.

7. A super-powerful new chipset

While the iPhone 15 and iPhone 15 Plus have inherited the excellent A16 Bionic chipset from the iPhone 14 Pro line, there’s something new powering the iPhone 15 Pro and iPhone 15 Pro Max.

Dubbed the A17 Pro, this is Apple’s latest smartphone chipset, and it delivers up to 10% faster CPU performance, offers a 20% faster GPU, and even has the ability to drive hardware-accelerated ray tracing, which should deliver some impressive graphics in future iOS games. And the Neural Engine performance, which governs iPhone smart features, has been doubled. 

Some of those figures are more impressive than others. But a year after launch the A16 Bionic still easily rivals the best chipsets in Android phones, so the A17 Pro should be a real beast.

TechRadar's Year in Review: AI revolution, smartphone evolution, and visions of the future

If I had to sum up 2023 in one word it would be AI. Okay, technically that’s two initials, but let’s not quibble – because there’s no doubt that it provided the year in tech with its main story arc. Artificial intelligence was everywhere this year, as every company in the world gawped at the massive impact of ChatGPT, and decided they wanted to jump aboard that bandwagon. You could barely move for new chatbots, new image generators, and new AI-enhanced features in every device released in 2023. And there’s no sign of that changing in 2024; in fact, we expect it to be an even bigger deal. Elsewhere, phones and laptops did much the same as they had the previous year – well, except where they had new AI-enhanced features – so it was in the virtual reality space where bigger changes were afoot. If the Meta Quest 3 was impressive then the Apple Vision Pro looks to be genuinely game-changing, and we can’t wait to see what impact it has in the next 12 months. Of course we also saw plenty ...

Microsoft and Sony enter "binding agreement" to keep Call of Duty on PlayStation

Microsoft has announced that it has reached a "binding agreement" with Sony, pledging to keep Call of Duty on PlayStation following the acquisition of Activision Blizzard.  With Microsoft having won its anti-trust case with the US Federal Trade Commission , its planned acquisition of Call of Duty developers Activision Blizzard has taken a big step closer to becoming a reality. In order to alleviate the concerns of monopoly-building that got Microsoft in legal hot water to begin with, the head of Xbox, Phil Spencer, announced yesterday via Tweet that it has entered into an "agreement to keep Call of Duty on PlayStation."  This agreement will no doubt come as a relief to fans concerned that Microsoft's acquisition plans might result in Call of Duty becoming an Xbox exclusive, following in the footsteps of future Bethesda releases. Since Microsoft's acquisition of Bethesda caused the studio to break its tradition of offering titles cross-platform for upcomi...

This Stardew Valley-like farming sim plays at the bottom of your screen so you work and play at the same time

Stardew Valley and Animal Crossing are among some of the best choices out there if you're looking for a game to get swept up in for hours at a time. But, if you're a fan of management sims and a multitasker as well, this upcoming farming sim will likely pique your interest.  Developed by Mister Morris Games, Rusty's Retirement is an idle-farming simulation game that runs at the bottom of your gaming monitor, allowing you to focus on other tasks like working while you tend to your crops. Set to release in Q1 2024 on Steam , the idle sim puts you in the shoes of a wholesome robot as you grow crops and use them to produce clean and energy-efficient biofuel. Having gathered this "vital robot power source," you'll then need to sell your harvest to the other machine inhabitants of your settlement. This, in turn, will let you reinvest the money into expanding your farm. If you're a terrible procrastinator (like me) this might not sound like your cup of tea...
