I’ve always been on team Regular Size when it comes to iPhone Pro models, even in years when the larger Pro Max models have gained exclusive features, like the 5x telephoto “tetraprism” camera in the iPhone 15 Pro Max (which expanded to both models in the iPhone 16 Pro). Despite the more expansive screen size, the Max has always seemed too bulky to carry around all day. 

But a host of rumored features and design changes for the upcoming iPhone 17 Pro Max has me weighing the benefits of embracing Apple’s biggest phone.

I know it might seem silly to be thinking about the next iPhone models in the heat of the summer, but here’s the thing: September is just two months away, which means now is the time when people start thinking about fall budgets and whether the iPhone they’ve been holding onto can make it through one more year.

What I’m seeing so far has me very interested indeed. Now, I’m looking forward to September for more than simply cooler weather and hot beverages. Here’s a rundown of some of the features rumored for the iPhone 17 Pro Max that I’m most curious about.

Making the case to go larger

The iPhone Pro Max models are tanks compared to the rest of the line — well, they’re not on the toughness level of the Samsung Galaxy XCover 7 Pro, so maybe they’re more like solid midsize SUVs. But they’re notable for their larger screens, bigger bodies and especially for having room for more of everything in an iPhone.

And that includes a larger battery. The Max models already have more battery space than other models, but the iPhone 17 Pro Max could end up being almost half a millimeter thicker, at 8.725 mm, according to a May post by 9to5Mac. Has anyone ever asked for a more bulky iPhone? Actually, yes, yes and yes.

Add the new Adaptive Power feature in iOS 26, which uses AI to distribute power more efficiently when demand is high, and we could see a boost in daily use before reaching for a charger. (Then again, Adaptive Power could be a software workaround that could mean longer life using the same physical battery size.)

If you’re already committed to carrying a larger iPhone, a tad more thickness and heft isn’t too much more to shoulder.

The back of the iPhone 17 Pro case is also rumored to shift the Apple logo down from its current perch. That doesn’t seem like a big functional change but it should help soothe folks who choose to add a clear MagSafe case, since the logo will be centered within the MagSafe area. You can’t say Apple doesn’t sweat the design details.

There are also rumors that the iPhone lineup will include a new sky blue color, about which I have opinions.

Bring on all the camera upgrades

We can’t talk about the case without mentioning the camera bump, which could become a more expansive camera island (or maybe on the larger iPhone 17 Pro Max, it will be more like a camera continent) that stretches across the width of the iPhone back, according to CAD renders by Majin Bu.

That expanse may include an upgraded 48-megapixel telephoto camera, which feels overdue for a top-tier camera system. Granted, it will probably take extra steps to capture photos in the full 48-megapixel resolution, as is the case with the current main Fusion camera in the iPhone 16 Pro models, where images are “pixel-binned” with multiple pixels grouped together to enhance light gathering ability. But given the great results we’ve seen from the 48-megapixel camera in the current models — the iPhone 16E leans heavily on that resolution using its sole rear-facing camera — extending it to the telephoto camera would definitely be a win for photographers.

Speaking of resolution, a 24-megapixel front-facing camera is expected, up from 12 megapixels, so perhaps my selfies will look better. More likely, it’s to boost the next rumored feature.

Video recording makes a leap

Cameras on both sides will reportedly work together with dual video recording using the built-in Camera app, a boon for conducting interviews or making reaction videos where you want to see both sides of a conversation. Third-party apps have been able to tap into this capability for some time, but haven’t been available as a default option.

Not as important for everyday use, but interesting in terms of advancing the state of the art, the iPhone 17 Pro Max could support 8K video recording, as speculated by MacRumors after reports that 8K was tested for the iPhone 16 Pro. The iPhone is swiftly turning into a production video camera, from features such as 28 Years Later to custom cameras built from iPhone tech in the F1 movie.

An improved cooling system

Recording video in 4K resolution, much less 8K, is a demanding, power-hungry task that leads to heat build up. In already warm environments, it can even overheat the iPhone and temporarily shut it down. So the prospect of a new internal cooling architecture, while being invisible to iPhone owners, has me nerding out just a little.

According to Majin Bu and others, the iPhone 17 Pro models will feature a “vapor chamber” cooling system. As the processor heats up, a small amount of liquid in the chamber evaporates and condenses in cooler areas, then gets passed back to the hot areas.

Wi-Fi 7 and fast cellular via a new Apple modem

This is more geeky and less obvious to everyday phone owners, but that’s also kind of the point. The iPhone 16E shipped with Apple’s C1 cellular modem, Apple’s first homebrew cellular hardware it has been trying to build in order to wean its dependence on Qualcomm, which has provided the modem hardware in previous iPhone models.

However, the C1 lacks a faster millimeter wave cellular network and does not support Wi-Fi 7, even though it’s more conservative about power usage (and still performs well), an acceptable tradeoff for the budget phone in Apple’s lineup.

But for the iPhone 17 Pro Max, we’re talking about the next professional models, and an iPhone Pro in 2025 can’t ship without the latest, fastest wireless technology. It would be more realistic to see Apple stick with Qualcomm for the Pro line than include the C1 — but I suspect a C2 is coming.

According to MacRumors, the Wi-Fi 7 compatibility could be provided by a separate dedicated chip designed by Apple.

These aren’t the only iPhone 17 Pro rumors we’re tracking, but right now they’re the ones that have me looking at my calendar and wishing September could arrive just a little faster.
