Rumours and speculation surrounding upcoming smartphones could keep a news site going on their own. No sooner has a device launched, than the next iteration of that device appears in some form on the internet. But when it’s a new phone that doesn’t have a predecessor to compare to, the rumour mill gets even more excited.

The Apple iPhone 17 Air, or iPhone 17 Slim, is such a device. It’s fresh, new, and exciting. And while we don’t know if it will even launch – there are no guarantees the rumours will become a reality after all – it’s appeared in so many leaks of late, it would be a surprise if there wasn’t an element of truth in them.

As such, the latest leak surrounding the skinny iPhone comes from leaker Majin Bu on X, and it shows what looks like a dummy case for the iPhone 17 Air alongside a dummy case for the iPhone 17 Pro. Not a great deal is given away from the image, but it does further reiterate just how slim the iPhone 17 Air could be against the rest of the iPhone 17 range.

We’ve previously seen renders comparing the iPhone 17 Air to the iPhone 16 Pro so this new image offers some extra supporting evidence from another source highlighting the potential difference between the Air and Pro models. This source is claiming the comparison device is the rumoured iPhone 17 Pro rather than the current iPhone 16 Pro, but it’s unlikely the iPhone 17 Pro will be thicker than the iPhone 16 Pro.

How slim could the iPhone 17 Air be?

Previous reports have claimed the iPhone 17 Air will come in at 5.5mm thick, which compared to the iPhone 16 Pro’s 8.25mm would be proportionate to what the picture shows. That 5.5mm measurement has been detailed a number of times, and while the latest image posted on X doesn’t provide any further measurement details for the iPhone 17 Slim or iPhone 17 Pro, it suggests the iPhone 17 Pro will be similar to the current iPhone 16 Pro, with the iPhone 17 Slim considerably thinner. 

Interestingly, 5.5mm isn’t actually the slimmest product Apple offers – the iPad Pro (M4) is slimmer at 5.3mm, but it would be slimmer than what is expected for the Samsung Galaxy S25 Edge, rumoured to measure 5.84mm. 

Of course, nothing is official for the Apple iPhone 17 Air as yet, and even if it does appear, it’s not due until much later this year, likely September when the iPhone 17 series is expected to debut. 

Samsung’s Galaxy S25 Edge, meanwhile, the other slim device consistently being talk about currently, is not only official as Samsung itself teased it, but it is expected to launch in mid-April so it will arrive much sooner than Apple’s alternative.

The iPhone 17 could face a supply shortage that makes it hard to buy

The expected date of the iPhone 17 launch is less than five months away, but Apple's initial inventory buildup has run into a few hiccups. Before launching a new device — especially one that will likely sell out quickly — companies tend to make sure there is sufficient supply to meet the demand. However, a shortage of a vital component means Apple isn't able to produce iPhone 17 devices as fast as they need to.

The component in question is low thermal expansion coefficient, or low-CTE, fiberglass cloth. Low-CTE fiberglass cloth is a key part of managing heat. In a closed, tightly-packed environment like an iPhone chassis, heat isn't able to dissipate as easily. Without a way to handle it correctly, the increased temperatures can cause other components to expand. While this usually isn't enough to outright break a phone, it can reduce its longevity, result in performance problems, and have a serious impact on battery life.

iPhone 17 Pro may get a wild, must-have accessory that beats a case
Render of iPhone 17 Pro Max.

The Apple iPhone 17 Pro may get an unusual customization option, if an image showing a wild new accessory type is accurate. Instead of just wrapping your phone in a case or a skin, the iPhone 17 Pro’s distinctive camera module may support colorful panels to spice up the look of the phone, and make good use of all that blank space we expect to see around the cameras.

Anyone who has seen early renders of the iPhone 17 Pro’s possible design will have been struck by the large camera module on the back, which appears flat and houses three main cameras on the left, with a flash unit and another sensor on the right. The space between them is entirely unused, and that’s where the rumored panels come into play.

The iPhone is renowned for its ability to start entire trends and drive the smartphone industry in new directions. 

Beginning with the launch of the original iPhone in 2007, which transitioned the industry from resistive to capacitive touchscreens and eliminated the need for a stylus, the iPhone also defined the current smartphone with the introduction of the App Store and the app economy.
