IPhone 15 and USB-C: Expect a Cable Mess, but It Might Not Bug You
Commentary: USB-C’s versatility in charging and data transfer brings complications that millions of customers will now get to experience firsthand.
I love USB-C, the data and charging port I first encountered in my 2016 MacBook Pro that’s now spread to almost every device in my life.
I wanted a USB-C iPhone in 2018, back when Apple first added that tech to the iPad Pro. I grew more optimistic in 2021, when Apple spread USB-C to lower-end iPads. And though I’m skeptical that regulation is the best way to direct product development, I’m not displeased that the European Union has now pushed Apple toward USB-C. Charging everything with USB-C is great for me.
So I’m psyched the iPhone 15 models all get USB-C ports. But here’s the bad news Apple didn’t share at its iPhone launch event Tuesday: Millions of people entering the USB-C ecosystem will encounter the technology’s ugly side, too.
The utility and flexibility of USB-C are tainted by confusion over just what the heck comes along with that USB-C port on the side of a device and the cable you plug into it. In short, it’s not always obvious whether your device or cable supports high-speed data transfer, high electrical power for fast charging, both, or neither.
As the rumors predicted, the iPhone 15 will ship with a USB-C port and charging cable that’ll give customers a taste of the trouble. That cable reportedly will be fine for charging but will transfer data at a mere 480 megabytes per second, the poky speed that arrived with the USB 2.0 standard from 2000.
During its launch event, Apple conspicuously avoided saying anything about how fast the iPhone 15 USB-C port is, but the spec sheet says it’s only slow USB 2.0. The iPhone 15 Pro models will work at the more useful 10Gpbs speed of USB 3.
More from the Apple event
For most folks, the problem is likely to be merely an inconvenience. But it reflects the difficulties of the vast USB ecosystem, where the pressure to keep costs low is fierce and certification isn’t required. USB-C is a much faster, more useful connection technology than the Apple Lightning port iPhone users have had since 2012, but Apple customers will have to endure some pain leaving the cozy Lightning world.
Apple didn’t respond to a request for comment for this article. But it did tout this major change on what’s arguably the single most important gadget on the planet. For one thing, USB-C means a single charging cable is all you need for many Apple devices. For another, you’ll be able to use your iPhone to charge your AirPods. And on iPhone 15 Pro phones, you’ll be able to record data-intensive 4K 60fps ProRes video to an external storage device.
The triple whammy USB mess
Part of the problem with USB is that the term actually refers to three separate standards. Let me explain.
The original standard, Universal Serial Bus, governs how devices identify themselves and send data across a connection. USB arrived in 1996 with a top speed of 12Mbps, but USB 2.0 was much more useful at 480Mbps, enough for printers and thumb drives. The first big speed jump after that was USB 3.0 in 2008 at 5 gigabits per second, better for external hard drives. Successors hit 10Gbps, 20Gbps, and most recently 40Gbps with USB 4. The upcoming USB 4 version 2 should reach 80Gbps. That’s good for high-performance storage systems, fast networks, and big, high-resolution monitors.
The next standard is USB-C, which refers only to the oval-shaped connector technology. Earlier in USB-C’s history, it was common for Android phones to support only slow USB 2.0 data transfer speeds, though that problem has faded with newer models. The newest USB standard, USB 4.0, requires USB-C ports, so as time goes by, it’ll be fairer to equate USB-C with high speed.
Last is USB PD, short for Power Delivery, which governs how USB is used for charging at rates up to 240W. Most devices don’t require that much power, but they do need to know how to negotiate electrical matters — for example, whether a portable battery should charge your laptop or vice versa.

Having three standards — USB, USB-C and USB PD — makes it harder to understand the abilities of all your devices and cables.
Worse, plenty of device manufacturers trying to cut costs and quickly ship products skip the certification process that the USB Implementers Forum offers. Unlike with Intel’s Thunderbolt, which developed the fast data transfer approach in modern USB, there’s no requirement to pass tests.
Low costs fuel USB-C’s problems
Nobody wants to spend $60 instead of $15 for a USB cable. But be careful: You get what you pay for, roughly. It’s more expensive to build cables that support high-speed data or high-power charging. One rule of thumb: Cables billed as «charging cables» in my experience don’t bother with the extra cost of high-speed data support. That includes the USB-C cables Apple itself shipped with MacBooks for several years.
One affordable cable I saw billed itself as a USB 4 product, but on deeper inspection, it turned out to support only USB 2.0 data transfer. Either the manufacturer was confused, lying, or trying to argue that the cable would work in a USB 4 port even if it only supported slow data rates. (USB’s good backward compatibility means slower, older products generally still work fine when attached to newer ones.)
I haven’t struggled too much with the slow cable problem. Mostly I use USB-C for charging, and my devices that need fast connections stay attached to their own fast cables.
But problems can happen. A couple of months ago, when I got a new Canon mirrorless camera, I was caught on a trip with slow cables that really bogged down the process of transferring photos to my laptop.
When USB-C is a problem and when it’s not
The good news for future iPhone owners is that most of them won’t have to care much about whether they have a slow cable. Indeed, iPhone 15 non-Pro phone owners won’t be able to benefit from the speeds of a fast cable even if they have one.
Data rates were more important in the olden days when we used iTunes to sync music and photos between laptops and iPhones. Even as photo and video files have exploded in size with 50-megapixel phone cameras and 4K video, most of us get that data off our phones with mobile networks, Wi-Fi and AirDrop, not with cables.
That’s the big reason Apple could mostly justify shipping an iPhone 15 with a USB 2.0 cable.
Now, for serious data hogs, the kind of person who’s shooting many gigabytes of 4K ProRes video, a faster cable is useful. It’s one reason I’ve been annoyed with the Lightning port on my iPhone. Those customers will, I hope, generally be discriminating enough to find a high-quality cable for their needs — or, if rumors are correct, just use the faster cable that Apple will ship with iPhone 15 Pro models. (Apple hasn’t yet revealed what’s ships with the new phones.)
I prefer buying USB-C products that have passed USB-IF’s compliance testing. I look for the USB-IF certifications, and I love it when companies like Plugable attach clear descriptive labels so we don’t have to decode USB-IF icons. (And most products don’t even have icons.)

But if you’re nervous about doing the product comparisons yourself, you can always let Apple sales staff steer you to higher-end Apple USB-C accessories that generally work well together even if they’re often more expensive than third-party products.
USB-C transition less painful than Lightning
There was plenty of kvetching when Apple switched to the Lightning port, even though it was clear Lightning was superior to the bulky, fragile 30-pin connector that preceded it. I’m expecting more complaints with the iPhone’s USB-C switch as people discover that all those cables they have stashed in glove boxes, office desks, school backpacks and bedside tables have become obsolete.
But the good news is that USB-C is already very well established, and not just on MacBooks and many iPads. The oval-shaped connector is on modern Android phones, Windows laptops, Nintendo Switch gaming consoles, iPad Pro and Air tablets, Sony noise-canceling headphones and countless other devices. There’s a good chance a lot of us already have some spare USB-C cables lying around.
When I talk to USB-IF executives about the USB-C’s labeling problems, they assure me that most people don’t notice any sort of bother, and that the gradually maturing technology will mean incompatibilities and product shortcomings eventually will slip into the back of our collective junk drawers.
I hope so. For me, the flexibility and power of USB-C is well worth the pain. But I do wish there wasn’t so much pain.

ChatGPT-5.2 Is OpenAI’s Answer to Google’s Gemini 3 Pro
The latest ChatGPT model could be your new work sidekick.
Last Thursday, OpenAI announced ChatGPT-5.2, which offers better performance across the board. It’s also the company’s strongest model yet for science and math. In the announcement press release, OpenAI says that people using the latest model for work-related tasks will see the most benefit, not necessarily people who use ChatGPT day-to-day.
«We designed GPT‑5.2 to unlock even more economic value for people,» the statement said. «It’s better at creating spreadsheets, building presentations, writing code, perceiving images, understanding long contexts, using tools, and handling complex, multi-step projects.»
Earlier this month, OpenAI CEO Sam Altman sent an internal «code red» memo to alert employees about the growing threat from competitors — specifically Google and its advanced Gemini 3 chatbot, released in November. The move echoes Google’s own «code red» memo from a few years ago, sent when ChatGPT launched and captured global attention. In just a few short years, the roles have reversed: Each company now sees the other as its main rival in the AI race.
Open AI also launched GPT-Image Model 1.5, an updated AI image model, on Tuesday to challenge Google’s Nano Banana Pro, which currently sits at the top of the list of the best AI image generators at CNET.
(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

There are three models of GPT-5.2. GPT‑5.2 Instant is designed to be fast and helpful for everyday activities. GPT‑5.2 Thinking is the most advanced version of GPT‑5.2 for professional, real-world tasks. And OpenAI says GPT-5.2 Pro is «our smartest and most trustworthy model yet, for difficult questions where a higher-quality answer is worth the wait.» OpenAI says that the entire ChatGPT-5.2 family provides meaningful upgrades from past versions for work and learning.
For developers, ChatGPT-5.2 is designed to be a robust model for building agents, thanks to improvements in general intelligence, long-context understanding, agentic tool-calling and vision. (In AI and software development, «agents» are AI systems that can perceive information, such as user inputs, reason about what to do, and then take action, such as run code or operate software.)
The latest model of ChatGPT begins its rollout on Thursday, starting with paid plans, and is now available to all developers.

My OnePlus 15R Review: A Lovely $700 Phone That’s Held Back by Its Compromises
The $700 Android phone has a lot to like for OnePlus fans who want a giant battery for less money than its flagship sibling.

Pros
- Excellent battery life and charging speeds
- Big and responsive display
- 120fps video looks gorgeous
Cons
- Lacks wireless charging
- More expensive than the OnePlus 13R
- Mixed camera quality
- Short software support compared to competing phones
The $700 OnePlus 15R’s standout feature is its massive 7,400-mAh silicon-carbon battery, one of the largest I’ve ever encountered on a phone. In my testing, it easily lasted two days between charges, even with plenty of media streaming, gaming and photography.
But it was the 15R’s hypersonic fingerprint sensor that impressed me even more, as it’s a feature I hadn’t seen on a midrange flagship phone before. It makes unlocking the phone feel much smoother than an optical fingerprint sensor, especially since it doesn’t require a bright light to function. I hope to see it become available on even cheaper phones, but for now, having it on the OnePlus 15R is nice.
Upgrades like these make the OnePlus 15R feel premium despite it being the step-down option from the $900 OnePlus 15. The phone’s features rival those of more expensive phones, such as the $799 Samsung Galaxy S25, rather than cheaper competitors like the $650 Galaxy S25 FE or the $499 Google Pixel 9A.
And with that $700 price, you’re definitely paying for those upgrades. OnePlus notes that the $700 starting price (for 12GB of RAM and 256GB of storage) might change. «Product pricing can vary in different countries and regions due to various local market factors,» OnePlus said.
But even at $700, it’s worth considering some of the things you don’t get with the OnePlus 15R. For example, the 15R comes with a 55-watt fast charger in the box and supports 80-watt wired charging speeds when paired with the corresponding OnePlus wall plug, but it lacks wireless charging. The previous R model, the OnePlus 13R, also didn’t have wireless charging, but it did have a telephoto camera that the 15R doesn’t, which somewhat made up for it.
The phone’s Snapdragon 8 Gen 5 chip is a step down from the OnePlus 15’s Snapdragon 8 Elite Gen 5 processor, but I still found it fine for gaming, multitasking and recording high-resolution slow-motion videos. The OnePlus 15R comes with four years of software updates and six years of security updates. It’s fine, but it falls short of Samsung’s and Google’s seven-year commitment to both.
OnePlus fans who don’t want to spend top dollar for the latest OnePlus 15 will find a lot to like with the 15R. But, like the 13R, it’s important to consider the compromises the 15R makes to see if any of them are potential dealbreakers.
OnePlus 15R’s design, specs and features
My OnePlus 15R review unit is the mint breeze edition, a light green color that encompasses the back of the phone, the side rails and the camera bump. A darker charcoal black model is also available, and is the sole color if you opt for the $800 model with 512GB of storage. The design is similar to the OnePlus 15, with the main difference being the 15R’s dual-camera setup versus the three on the more expensive phone.
There’s a new programmable shortcut button called the Plus Key, located across from the volume and lock screen buttons. Similar to the Action button on newer iPhone models, it can trigger shortcuts like toggling between sound and vibration, opening the camera or turning the flashlight on. I wish I could use it to launch any app, though, which is possible on Apple’s Action button using shortcuts.
The phone’s 6.8-inch display is expansive, and I found it particularly good for watching or playing media. But it’s too big for me to use one-handed beyond scrolling. The display can continuously run at a smooth 120Hz refresh rate, which has become the standard across all Android phones in this price range. There are certain mobile games, like Call of Duty Mobile, that can take advantage of the display’s full 165Hz capability, but I can’t use that higher refresh rate when I’m not gaming. The OnePlus 15 has the same limitation. This surprises me, as I’ve seen less powerful phones with a consistent 165Hz refresh rate.
For example, when I played the game Dead Cells, it looked great on the phone, and the touchscreen was responsive, which helped especially during frenetic moments battling through successive deadly monsters. But its refresh rate is constrained to 120Hz. I find that odd, because I’ve seen this game run at 165Hz on phones that include that option. I found other games, such as Red Dead Redemption, Fortnite and Fall Guys, to load quickly at high graphics settings too. Red Dead ran at a steady 40 frames per second (fps) in its performance mode, while Fortnite and Fall Guys ran at 60fps on their higher graphics options.
Perhaps it’s a choice to help extend battery life, but the OnePlus 15R’s large capacity would seem plentiful enough to handle some extra gaming workload. Most of the time, I’m happy if a phone can last a full day on a single charge. With the OnePlus 15R, I easily got through two days and nights on a single charge. In CNET Labs’ 3-hour YouTube streaming test, where phones start with a full battery, the OnePlus 15R dropped to 89%, the same as the $829 iPhone 17, and just behind its sibling, the OnePlus 15, which ended at 90%.
The OnePlus 15R comes with a wall charger, a rarity for most phones sold in 2025. While the included 55-watt fast charger doesn’t support the phone’s fastest 80-watt speed, I was able to get it from 0% to 49% of its 7,400-mAh battery capacity in 30 minutes. Considering most phones we cover typically have battery capacities between 4,200 and 5,000 mAh, that’s a lot of power even at half capacity.
30-minute wired fast charging test
| Phone | Percent increase | Battery capacity | Wall plug wattage | Comes with plug? |
|---|---|---|---|---|
| OnePlus 15 | 72% | 7,300-mAh | 80W | Yes |
| Apple iPhone 17 | 69% | 3,692-mAh | 40W | No |
| Samsung Galaxy S25 FE | 69% | 4,900-mAh | 45W | No |
| OnePlus 15R | 49% | 7,400-mAh | 55W | Yes |
| Samsung Galaxy S25 | 47% | 4,000-mAh | 30W | No |
| Google Pixel 9A | 46% | 5,100-mAh | 45W | No |
If you prefer to use more universal power adapters with the USB-PD standard, the OnePlus 15R will charge at a slower 18-watt speed. But even with that limitation, in real-world use, it’s only slightly slower.
Although the 15R doesn’t support wireless charging, OnePlus sells a case that allows for attaching magnetic accessories. OnePlus provides a sandstorm black case with the phone, which I found perfectly suitable for attaching my wallet accessory that doubles as a kickstand.
In benchmark testing for the CPU and graphics power, the OnePlus 15R scored comparably to phones like the Samsung Galaxy S25 — which runs on a custom edition of last year’s Snapdragon 8 Elite processor — and was slower than the OnePlus 15 and 13R. Compared to the prior OnePlus 13R, which has the 2023 Snapdragon 8 Gen 3 chip, the 15R scored similarly in the graphically intense 3D Wild Life Extreme test and notably higher in the computationally intensive Geekbench 6.0 CPU benchmark.

OnePlus 15R cameras
I’m bummed that the OnePlus 15R doesn’t have a telephoto camera, but the 50-megapixel wide-angle and 8-megapixel ultrawide cameras can hold their own, especially in daylight settings or when recording at 4K 120fps videos.
Using the latter, I recorded Gizmo, my friend’s cat, as he darted between a flurry of poses while squished between two couches. And when visiting the 3 Daughters Brewery holiday train display in St. Petersburg, Florida, I was able to capture the model trains as they zoomed throughout the multitier village. The videos have a smooth clarity.
When it comes to photography, I would say the OnePlus 15R is on par with other $700 phones. Daylight photos have lots of detail but tend to skew warm in tone. I shot a photo of a sunset at a beach in Siesta Key, and the image has lots of orange colors and good texture in the whirling clouds in the sky.
I noticed that the camera tends to add an aggressive blur to images when it focuses tightly on a subject. For instance, in this photo of a dark chocolate gelato, the dessert underneath is blurred out as if I had taken it in portrait mode. But it’s not, it’s in its standard photo setting.
The OnePlus 15R did a decent job of getting photos of my friend’s fast-moving pets, albeit at the cost of some detail. In this photo, the camera is able to focus in on Kinley’s face, although it struggled a bit to capture the light of both eyes. Snickers, the dog in the background, was also moving around during this moment, but comes out as a background subject. This is actually good, though, as it’s a naturally more challenging subject in a lowlight area.
I have mixed feelings about selfie images from the phone’s 32-megapixel front-facing camera. They aren’t bad, but I feel like the 15R had trouble focusing on me, whether I was outdoors or indoors. This photo, taken on a street in St. Petersburg, is washed out despite otherwise being taken in broad daylight.
And it’s a similar situation for this selfie I took in an indoor brewery. The photos aren’t bad — they just aren’t as good as I’d prefer from a $700 phone. It’s more comparable to what I see from phones that are closer to $500, like the Motorola Edge and the Pixel 9A.
OnePlus 15R: The bottom line
The OnePlus 15R’s features make it an excellent starter gaming phone. I often thought about the RedMagic 11 Pro while reviewing the 15R. RedMagic’s $749 gaming phone has impressive specs that easily run any game you throw at it, and its 7,500-mAh silicon-carbon battery. But RedMagic seems to hit its reasonable price through a frustrating software experience that even includes advertisements when you open its web browser.
OnePlus chose not to skimp on the 15R’s display or the battery, and would rather make its cuts by going with a slightly less powerful processor, skipping wireless charging and omitting the telephoto camera. The result is a mighty $700 phone, even if it’s noticeably not going to outdo the more expensive OnePlus 15.
The phone is ultimately fantastic as a media powerhouse that can run for days on a single charge. But to make sure it’s a good fit, you’ll want to decide whether the lack of wireless charging is a deal-breaker.
If you want a phone with more features and less focus on gaming or a large battery, it’s worth considering phones in the $500 to $650 range, such as Google’s Pixel 9A and Samsung’s Galaxy S25 FE.
How we test phones
Every phone tested by CNET’s reviews team was actually used in the real world. We test a phone’s features, play games and take photos. We examine the display to see if it’s bright, sharp and vibrant. We analyze the design and build to see how it is to hold and whether it has an IP-rating for water resistance. We push the processor’s performance to the extremes using standardized benchmark tools like GeekBench and 3DMark, along with our own anecdotal observations navigating the interface, recording high-resolution videos and playing graphically intense games at high refresh rates.
All the cameras are tested in a variety of conditions, from bright sunlight to dark indoor scenes. We try out special features like night mode and portrait mode and compare our findings against similarly priced competing phones. We also check out the battery life by using it daily, as well as running a series of battery drain tests.
We take into account additional features like support for 5G, satellite connectivity, fingerprint and face sensors, stylus support, fast charging speeds and foldable displays, among others that can be useful. We balance all of this against the price to give you the verdict on whether that phone, whatever price it is, actually represents good value. While these tests may not always be reflected in CNET’s initial review, we conduct follow-up and long-term testing in most circumstances.
