On the same day Apple revealed its new iPhone 17 lineup, chip designer Arm is introducing its next generation of processors bundled into its new Arm Lumex platform. These processors will likely make their way into premium Android phones coming in 2026 — and improve their AI capabilities without draining device batteries faster, Arm says.

«It’s pretty amazing how there’s been kind of this insatiable amount of performance being asked for [by our customers], and a lot of it’s around AI, as well as some graphics workloads,» said Chris Bergey, senior vice president and general manager of Arm’s client line of business.  

Arm’s processors have traditionally been the centerpieces of holistic systems-on-a-chip, which power smartphones. For instance, Arm’s previous top-end central processing unit, the Cortex X925, released last year, is featured in Samsung’s Exynos 2500 chipset, which powered the Galaxy Z Flip 7 and MediaTek’s Dimensity 9400 chipset, found in the Oppo Find X8 Pro. 

It’s likely that Arm’s new chips, either on their own or bundled into the company’s Arm Lumex platform, will power premium Android phones and other devices next year. But it faces more competition as Qualcomm (which used Arm CPUs in older chips like the Snapdragon 8 Gen 3) has shifted to its internally designed Oryon CPUs in its latest silicon — which was the subject of its own tech licensing clash over the last few years between the two chip companies. 

Arm’s new CPU range has shifted with a new naming paradigm. The successors to the X925 are two different chips: the highest-end C1-Ultra, which boasts 25% greater performance over its predecessor, and the next-most-powerful C1-Premium (no performance improvement given). The successor to the A725 chip is the C1-Pro, which has 12% greater efficiency. 

These CPUs also benefit from an evolution of their chip architecture called Scalable Matrix Extension version 2, which enables better AI performance. 

The new Arm Lumex platform combines these chips with the new Mali G1-Ultra GPU (which Arm says has 20% better performance and twice the ray tracing as its predecessor) for a system that can be plugged into larger chipsets. The end result: up to 5x improvement in AI performance, 4.7x lower latency for speech-based workloads (think live translation) and 2.8x faster audio generation, Arm says. 

The goal is faster performance without increasing the battery drain when running AI tasks that tax processing power. For example, a yoga tutor demo app running Arm’s new chips saw a 2.4x boost in text-to-speech to give faster feedback to users, the company said in a press release. 

As a supplier of chips and technology, it’s ultimately up to the phonemakers using Arm’s silicon to decide how much (or little) of the advancements they integrate into their devices. But as demand for generative AI like ChatGPT increases, so too does the drive to get that functionality working on phones as efficiently as possible, rather than relying on slower responses going to and from the cloud. So what will consumers see with devices running C1-Ultra chips and Arm’s new technology?

«I think what they’re gonna see is the ability to run amazing on-device AI and to do so with significant power savings, significant performance increases, and also third-party support,» Bergey said. «Not just first-party devices, but also third-party devices.»

One thing you can be sure of during an Apple event is that it will generate immense quantities of discourse among CNET’s seasoned nerds — and no, we don’t always agree with one another. 

Is the iPhone Air totally pointless and uncalled for, or the best design innovation since very thinly sliced bread? Both can be true, depending on whom you ask.

Among the many announcements on Tuesday that sparked conflicting opinions was a crossbody strap for the iPhone. After a back-and-forth in Slack, my colleague Zach McAuliffe and I have decided to put forth our respective viewpoints and allow you to be the judge.

Have you ever been walking down the street to meet your friend, navigating using Google maps and texting your pal to let them know you’re running late, when all of sudden: bam! A dude on a moped has whizzed past at high speed and removed your phone from your hand before you’ve even had a chance to realize what’s happened?

In London, this style of phone theft is a daily occurrence, and while it’s never happened to me personally, every time I step foot on the streets of the British capital, I’m immediately wary and vigilant.

Earlier this year, the Guardian reported that survey data from American insurance company SquareTrade showed that 39% of all European phone theft take place in the UK, and that 42% of British phone thefts occur in London. So common is it for your phone to be snatched by someone on a bike or moped that London’s Metropolitan Police issue special prevention guidance, featuring advice such as: «[when using your phone,] stand away from the roadside, close to a building or wall, so no one can come up behind you.»

I get that a crossbody is not a failsafe method to prevent iPhone theft. I would never advise someone to walk around a city in a state of blissful ignorance while their phone flaps hands-free against their body. But I do endorse it as a way to fend off opportunists on two wheels.

I can see other times the crossbody strap would come in handy, too. Frequently on my travels, I find myself on a boat, clutching the railing and taking pictures on my phone as the world passes me by. Always in these situations I’m concerned that just one clumsy slip could see my precious phone go the way of the Heart of the Ocean in Titanic. A crossbody strap would provide peace of mind in such moments to protect me against my own idiocy.

As a clumsy person who dreads having their phone stolen, I will be investing in one of Apple’s crossbody iPhone straps the moment they become available. I personally can only see the benefit in having my phone glued to my body as well as my hand.

Terrible idea: Zach McAuliffe, Staff Writer

When I saw Apple’s new crossbody strap for the iPhone, my first thought was, «I bet someone could cut that real easily and steal someone’s iPhone.»

But surely Apple thought of that and chose a cut-resistant strap made with something like Dyneema, right? Nope. According to Apple, the strap is made of recycled PET (polyethylene terephthalate) yarns. If you’re unfamiliar with this kind of yarn, it’s a synthetic fiber made from recycled plastic bottles. 

If you had a razor or something similarly sharp, you could cut through the strap like a hot knife through butter. Then there’s nothing stopping you from taking the iPhone. The decision to dangle a thousand-dollar device off a strip of non-cut-resistant plastic gives me so much anxiety.

Some people on Reddit said they’ve had their crossbody bags and purses stolen because someone cut the straps and ran or rode off, so it does happen. Granted, so does someone snatching a phone from your hand. But if I’m wearing my iPhone as a bag, I’m advertising that I have an iPhone and all you have to do is follow me for a second in order to cut the straps and take off with it.

Plus, if I’m my iPhone is tethered to me by a strap, I might be more cavalier with how I handle it. The strap and corresponding case are meant to keep the device safe, so I might take for granted things that could damage it out in the world. What if a car kicks a rock up and hits it, or I bump into a metal railing a little too hard or any number of things happen and my iPhone gets a new scratch or breaks? 

No, I’d much rather grip my iPhone like my life depends on it when the device is in my hand. And then I’ll slip my iPhone into my pocket for safe keeping like Bilbo Baggins after he finds the One Ring.

The crossbody strap is a bad idea. I know people have things taken all the time, but the strap is like wearing a sign around your neck that you have an iPhone and with a quick snip it could be yours! Hopefully Apple will make a cut-resistant strap in the future.
