iPhone 16 Pro Max review: bigger screen, bigger opportunities

Mario Bautista September 28, 2024

iPhone 16 Pro Max Intro

The iPhone 16 series is now official! Apple’s “Glowtime” event came and went, and we got an earful about Apple AI, new colors for the Apple Watches, Private Cloud Compute, and the new iPhones, of course!

It’s a quadruplet of new models, again, and the iPhone 16 Pro Max towers over all of them, of course. The biggest and best, the most powerful and most expensive, and the one with some extra camera tricks up its sleeve.

The iPhone 16 Pro Max gets a slightly bigger screen — now 6.9″ instead of 6.7″. There’s a new Camera Control button, and more features for pro video recording. What else?

iPhone 16 Pro Max Design and Display

The iPhone 16 Pro Max sticks to the design we’ve known since the iPhone 12 series. Yes, now it’s all covered in titanium, and there have been some facelifts, but the general guidelines are there.

For example, we have some more screen now, grown to 6.9 inches. But the iPhone 16 Pro Max itself is barely bigger, it just has a razor-thin bezel around the display. Cool.

As usual, the screen is protected by the Ceramic Shield on the front — a new generation of the shatter-resistant glass, Apple says —, and it’s rated IP68 for water and dust protection. Some months of use will show if it gets the magical random micro-scratches, which tend to appear on our beloved smartphones. USB C makes its second appearance on an iPhone ever — and with the Pro models, it’s a USB 3 port for much faster data transfer speeds. But you will need a cable that supports at least 10 Gb/s to make use of it, as that’s not what the iPhone ships with.

We have a new hardware button on all iPhone 16 models! A Camera Control Button, which operates as both a shutter and slider. It’s a capacitive area that’s also clickable, a light press allows you to shuffle through different settings for the slider, a hard press takes a snap. Or hold it in to record video. Swiping across will modify the currently-selected setting, like exposure, zoom, or bokeh intensity. Also, it’s a camera shortcut button — press it and the app opens up instantly.

It’s positioned on the right frame — or the top, if the phone is held in landscape. Kind of like Sony Xperia’s shutter buttons. But the iPhone’s Camera Control button is slightly more awkward, placed a bit far into the frame, so it feels a bit unnatural to use, especially on the Pro Max. You will need to adjust your grip, we’ll definitely be following if it’s something we can get used to.

Of course, the good old Action Button makes a return. Some people liked to make the Action Button their camera shortcut — now that this function is free, you can set it to open another app, put the phone in a special DND mode, light the flashlight, or something else.

In terms of colors, we the iPhone 16 Pro Max comes in:

Black Titanium
White Titanium
Natural Titanium
Desert Titanium

In the box, we have the phone, USB C cable, and nothing much more.

The phone still has a Face ID system for secure unlocks, hence why the Dynamic Island cutout at the top of the screen is still there, which is an acquired taste by now.

Pretty as ever (Image credit – PhoneArena)

The 6.9″ display panel is as pretty to look at as it has been for the past few years. Still OLED with deep blacks and pretty well-tuned colors.

As is common with pentile OLED matrix screens, holding it under precise measuring tools reveals that we do get a bit of drift towards the blues or greens, but the good news is that Apple’s True Tone mode works great to adjust the display’s cast and warmth depending on your ambient lighting.

It’s an HDR-capable screen with 2,000 peak brightness. We do measure fullscreen brightness, which shows that the iPhone 16 Pro Max is capable of sustaining a bit above 1,000 nits. Not bad for outside viewing, but we’d be remiss not to mention that Android flagships are usually topping that easily nowadays.

The big upgrade here is minimum brightness, which was not excellent on iPhones thus far. Now, it drops below 1 nit, which will make it quite comfortable for bedside viewing.

It has a 2868 x 1320 pixel resolution, which means sharpness is about 460 pixels per inch. The aspect ratio is 19.5:9, like before.

iPhone 16 Pro Max Camera

Upgrading the ultra-wide

Now that Apple has upgraded the main camera and the telephoto camera on the iPhone Pro Max in the past, it’s time for the ultra-wide to shine.

So, the main camera retains that 48 MP sensor that was an excellent upgrade a couple of years ago. The 12 MP zoom camera still comes with that 5x tetraprism lens. And now, we get a 48 MP ultra-wide camera to match that main one. Apple still does quad-pixel binning for 12 MP pictures with better light sensitivity, but you can choose to use full resolution — the Camera must be set to HEIF Max for this option to be enabled. Keep in mind, HEIF Max disables Live Photo, if that’s a feature you still rely on.

You will notice that the iPhone 16 Pro Max did not jump immensely in our camera score. It’s lagging behind the top score by a couple of points in every category, with only its new ultra-wide lensreaching the current “best” in video recording, which is 23. Our camera benchmark is a complex process, which takes the phones through a variety of tests and measures the experience from viewfinder and app comfort to actual photo quality and judging post-processing artifacts.

As for video, we are getting some massive upgrades to audio recording, with the power of AI and the iPhone 16 Pro‘s excellent microphones. You are be able to filter out and process voices from a recorded video. Basically, it seems to also record audio metadata and directional information, so you can edit out background noises or even do some slight “mastering” to make all voices within the shot to sound as if they are center-positioned (movie-like).

Slow motion capture has gotten a huge upgrade — now able to record 4K at 120 FPS. That’s a lot of frames that you can slow down at super-high res and aspiring vloggers or film enthusiasts would problably love to play with that.

An upgrade for Photographic Styles has also been introduced — now, we get even more control over how styles act and adjust vibrancy on per-color basis, if we wish. You will also be able to retroactively remove them from photos, so… kind of like advanced filters?

And, of course, we can’t not mention the AI image tuneups that were inevitable. iOS 18 has the new “Clean Up” tool in Photos, which allows you to easily remove an object, much like Google’s Magic Eraser feature. Apple has added a few nice animations to this and while the results are not always perfect, it’s a really cool tool to have.

That said, here’s how the iPhone 16 Pro Max camera performs:

Main Camera

As we are used to, photos from the iPhone 16 Pro Max are pretty striking and close to reality. Dynamics are handled great and colors are, more often than not, accurate. We specifically like how the iPhones handle greenery — smartphones, even the top-tier ones, often skew these colors. Skintones are also lively and close to real. One thing that irks us is that the iPhone 16 Pro Max does introduce some oversharpening. We feel this has been happening since Apple upgraded to a 48 MP sensor back with the iPhone 14 Pro series — kind of like Apple wants us to feel like the pictures are really that much sharper. Not an issue on phone displays, but we can spot it when we look at the photos on a big screen.

As the sun goes down, the iPhone 16 Pro Max camera still performs gracefully. There’s a lot of noise reduction and sharpening going on, but we feel it’s being handled tastefully here. There aren’t many visual artifacts, most detail is preserved, and — in this case — the sharpness of the photos looks pleasing.

Ultra-wide camera

And here’s the new ultra-wide camera. Nothing too different from the old one, but that’s not a bad thing. It’s tuned to have the same colors as the main camera, it handles dynamics very well (which is a challenging point for ultra-wide cameras due to their smaller aperture), and it seems to apply barrel distortion correction, which we can’t spot exactly, though if you happen to catch vegetation around the edge of the frame, you can see some weird halos or outlines around it.

Zoom Quality

The iPhone 16 Pro Max‘s tetraprism lens has a 5x magnification. From then on, it’s all digital, and Apple stops at 25x. Cupertino is not interested in the super-zoom wars, it appears. So, how’s the quality? Pretty good!

Unlike the main camera, Apple doesn’t seem to apply a lot of sharpening when postprocessing the zoomed photos. And we appreciate that — they may look a bit softer, but at least they feel more authentic and there are no outlines or contrasty auras around fine objects. The colors and dynamics, again, look great.

Selfies

The 12 MP selfie camera takes great photos. They are not super-sharp, but have plenty of detail, very good dynamic range, and most importantly — good skintones. Oddly enough, specific lighting can still get iPhones to trip up with skintones, making them appear too red. We’ve found that selfies during “Golden Hour” may get that effect, if there’s a large shadow behind you. But, aside from those odd cases, you will be getting good selfies.

iPhone 16 Pro Max Performance & Benchmarks

The 16 Pro Max has the new Apple A18 Pro chipset humming inside. It’s built on an improved 3nm process and comes with a 6-core GPU to power these gaming moments. And, Apple specifically stated that the improved thermals of the new iPhones will ensure at least 20% better sustained performance. A clear throwback to last year’s phones with the A17 Pro, which weren’t doing great in the heat department.

No joke, Apple is taking a foray into gaming — console-grade games have started popping up for iOS and iPadOS — and the new iPhones supposedly have improved cooling for better sustained performance. Sooo… benchmarks:

Well yes, both peak performance and sustained numbers are, indeed, better. But it’s worth noting that when we run the 3DMark test, the iPhone 16 Pro Max still starts off strong and throttles immediately after the first cycle. This is a benchmark that is designed to overload and overheat phones by running 20 times in one session. Current Android flagships can sustain their top performance for about 3 cycles — highly tuned ones like the ROG Phones can do so for 17 or all 20 cycles. The iPhone throttles faster but does not go as low as the Galaxy S24 Ultra in the example here.

We now get Wi-Fi 7 as well. It’s something that Android flagships were prepared for almost a year prior. It’s a new protocol and standard, which allows for much faster — and more stable — data transfers between your phone and router. You do need the latter to be Wi-Fi 7 compliant as well, of course.

But, Apple will also want it to shine in AI. There are exclusive NPU cores inside the A18 Pro to power those Apple Intelligence features that will be coming out throughout the year.

Storage options start at 256 GB and go up to 512 GB and 1 TB, like last year. Prices start from $1,199 — no change there, thankfully.

iPhone 16 Pro Max Software

AI will be the name of the game for a while, and iOS 18 is jumping into the fray loaded with various AI features. Well… some AI features. OK, most AI features will come later, starting in October with iOS 18.1. If you live in the US.

The planned featureset is truly huge and mixes on-device AI calculations with cloud-based AI services Which is why Apple developed a new infrastructure that it calls Private Cloud Compute — basically, a super-secure connection, so you can have a peace of mind when your iPhone is sending and receiving information from the servers. It’s all encrypted, all super-secure, and not even Apple can see or extract the data, Cupertino says.

So, what does AI do on launch? Image tuneups, generative editing, and other features we’ve seen before. Upcoming is the new Visual Intelligence, where you point the camera to something to get info about it, kind of like Google Lens. A new way to reorder your notifications, based on importance and personal meaning. Generated auto replies or assistance when composing messages and emails. And Siri will now be so smart that it can tell you how to do stuff on the iPhones that you don’t know about — basically killing a lot of How To articles on the Internet (besides “How to activate Siri?”)

iPhone 16 Pro Max Battery

Bigger battery, faster charging?

With a slightly bigger size, the iPhone 16 Pro Max does house a slightly bigger battery. Apple doesn’t reveal those “geeky numbers”, though, not for iPhones. Thanks to teardowns from tech pundits we now know that it’s a 4,685 mAh. Still smaller than the typical 5,000 mAh we’d get on an Android flagship, but definitely the biggest battery in an iPhone thus far.

But it also comes down to the CPU’s energy efficiency and iOS’ ability to manage and freeze background tasks. We typically get great battery life from the Pro Max models, and we are happy to report that the iPhone 16 Pro Max does not disappoint:

PhoneArena Battery Test Results:

22 hours of web browsing is nothing to snark at — we test that with a script, which scrolls and reloads pages constantly, so it simulates pretty active use. But then, we have 10 hours of YouTube streaming and 12 hours of gaming. Both of these activities are pretty demanding, so hitting 10 full hours of screen-on time with them is a pretty big deal. Again, since this is a phone, you will often turn that display off and leave it in standby, and this is where iOS shines. It preserves those percentages from trickling down while the phone is not in use, and we’ve found that the iPhone 16 Pro Max can confidently be a “two day phone”.

Apple hasn’t been in a hurry to get fast charging to its phones. The iPhone 16 Pro Max now gets upgraded MagSafe — 25 W MagSafe charging, up from 15 W. But wired charging is still capped at 20W. So, whether you choose to plop it on a MagSafe charger or plug it in, you will still get relatively same-ish charging speeds. And those are kind of slow by today’s standards. But, being realistic, you do get around 57% for only 30 minutes of charging, and that should be plenty enough to last you through the day.

iPhone 16 Pro Max audio and haptics

We don’t detect much difference in the speakers this year. Pro Max iPhones typically sound big and wide, with a sound signature that’s a bit scooped, but has a pronounced bass and silky highs. It’s the same case here. We still avoid pumping the volume up to 100%, since the highs may get a bit unpleasant up there, depending on what you are listening to. But a tick or two down from maximum sounds great.

The haptics are fantastic, as usual. This year, we have a second Taptic engine dedicated to the Camera Control button, so you get clear and accurate feedback with it, too. All the clicks throughout the interface are satisfying, precise, and fun.

Summary

Person using the iPhone 16 Pro Max and enjoying it

Good as ever (Image credit – PhoneArena)

The iPhone 16 Pro Max is a very solid smartphone, no surprises there. The elephant in the room is that it’s a bit of a “boring” upgrade. There’s nothing groundbreaking, nothing mind-bending. The market is now also saturated with AI platforms and apps, and we don’t think that Apple Intelligence generated as much buzz as some might have hoped.

You may be asking yourself “Can’t I just get an iPhone 15 Pro Max?” and we’d be hard-pressed to argue against this logic. The new camera is not exactly better, just slightly different. The AI features will be available for the 15 Pro Max. The Camera Control button and the new Photographic Styles — you will miss out on those, for what it’s worth. But, in general? The iPhone 15 Pro Max is looking very tempting right now.

But, since iPhones tend to be supported for a good 5 years, we think it’s realistic to assume that there will be a lot of people upgrading from iPhone 11, 12, or 13 series now. For them, the iPhone 16 Pro Max will feel like a pretty good jump.
