Google Pixel 9 Pro Fold review: A grown-up, glowed-up foldable

Growing up. It’s something we all do, and devices do too. While there’s been very little innovation in mainstream smartphones lately, foldable phones have been maturing over the last few years and finally seem to be coming into their own. It’s like they’re in the young adult phase of their lives, while the conventional “candybar” handset has largely been figured out. At least, on the outside, anyway.

If foldables are the products, then companies like Samsung and Google are the parents, and each of those two has taken a different approach. Samsung has been more experimental, letting its baby flail around in the playground, falling off swings and cracking its face. Google appears to have been more careful, perhaps sheltering its product before releasing it for the first time last year. And let’s not talk about the elephant in (or missing from) the room — Apple is probably waiting till its foldable is mature enough to skip straight to high school before exposing it to the world.

All that is to say the Pixel 9 Pro Fold feels like a glowed-up young adult, ready for reality. Though it would have been more apt to call this the Pixel Fold 2 (since it’s only Google’s second foldable), I can see why the company wants us to think of it as part of the 9-series. With the Pixel 9 Pro Fold, the entire Pixel 9 lineup feels refined and well-equipped to take on the competition. And maybe even win our hearts.

The Pixel 9 Pro Fold’s design

One of my favorite things about the Pixel foldable is its aspect ratio. Compared to the Galaxy Z Fold 6, which my colleague Sam Rutherford has described as more like a skinny baton, the Pixel 9 Pro Fold feels more like a conventional phone when folded. In fact, the Pixel 9 Pro Fold is so much an extension of the Pixel 9 series that its 6.3-inch external display is pretty much the same size as the Pixel 9 and 9 Pro.

But because that panel is encased in a frame designed to house a hinge for the flexible internal screen, the Fold actually looks more similar in size to my iPhone 15 Pro Max. When I picked them both up, the Pixel 9 Pro Fold felt a bit heavier, but I guessed that it was probably close to the iPhone 14 Pro Max in weight. I was wrong — the Pixel 9 Pro Fold is actually 17 grams heavier than the iPhone 14 Pro Max and 36 grams more than the 15 Pro Max. More importantly, at 257 grams (9.06 ounces), the Pixel foldable is 18 grams heavier than the Galaxy Z Fold 6.

It may not be the lightest foldable around, but the Pixel 9 Pro Fold certainly ranks among the thinnest. When open, its profile measures just 5.1mm (0.2 inches) thick, while Samsung’s Z Fold 6 is slightly thicker at 5.6mm.

Numbers alone don’t tell the entire story. Small dimensions look nice on paper, but the way the Pixel 9 Pro Fold feels to hold is a significant part of its evolution. Last year’s model felt a little unfinished, with a bit of a duct-tape vibe to its construction. This time, the device feels solid, thanks to its “aerospace-grade high-strength aluminum alloy” and “matte back with satin metal frame.” The external screen and rear are covered with Gorilla Glass Victus 2, helping it be more scratch-resistant.

Of course, as is usually the case with foldables, durability is a concern and something that we can only gauge with time. The good news is, Sam recently published a durability report after a year with the original Pixel Fold, and the device not only withstood the wear and tear of daily life, but also survived being in the general vicinity of an active toddler for 12 whole months.

Some quick final notes on the Pixel 9 Pro Fold’s design: If you’re right-handed, you might appreciate that the bottom right corner of the phone (when folded) is slightly curved. It rests nicely against your palm and is marginally more enjoyable than the experience for those who are left-handed, who might not like the sharper angle of the bottom left corner. I used the Fold in both hands and didn’t find this a major issue, but our videographer Hayato Huseman did not like the design for left-handed use.

I also have a minor complaint that the device is hard to open without first getting a fingernail in between the two halves, but I expect this will get easier in time. More annoying is the slight creak every time I open the phone, but this got smoother over time. On occasion, there’s also a mildly concerning rattle when I shake the Fold, which is something my friend Julian Chokkattu at Wired brought to my attention, so it sounds like a problem that isn’t unique to our unit.

I’ve asked Google if this is an issue with just our review samples or if it’s more widespread and according to the company “this is expected behavior that’s due to the telephoto camera VCM (voice coil motor). You will likely notice this on Pixel 9 Pro and 9 Pro XL as well.” I will say that I hear a similar (though less pronounced) sound when I shake my iPhone 15 Pro Max the same way, so this could just be the optical image stabilization system moving about.

A tale of two Pixel 9 Pro Fold displays

Gather up, aspect ratio nerds, have we got an adventure in intricate numbers for you! Though last year’s Pixel Fold had a 5.8-inch external display with an awkward 17.4:9 aspect ratio, this year’s model is much more intuitive. It’s the same 6.3-inch 20:9 screen as the standard Pixel 9, making it a more familiar size and shape. I’m a little bummed that it has the 1,080 x 2,424 resolution and 60-120Hz adaptive refresh rate of the base Pixel 9, as opposed to the sharper panel on the Pro (which goes down to 1Hz), but it’s not a huge problem.

Sam pointed out that there is the teeniest change in the Pixel Fold’s internal screen. The original was just under 5.875 inches wide when held in landscape, and while the new Pixel Fold’s interior display is the same size in the same orientation, in portrait mode it’s actually 5.625 inches wide. This means the Pixel 9 Pro Fold’s internal display has an almost square 1:1 aspect ratio that’s 8 inches wide diagonally, which is larger than its predecessor’s 7.6-inch panel.

This doesn’t dramatically improve things when you’re viewing widescreen content, and Sam would even call it a “very tiny downgrade” in that scenario. The new screen dimensions will make more of a difference when you’re gaming and multitasking than watching videos. The tweak appears to be more for compatibility, and I still had to live with empty space on either side of videos (in both portrait and landscape orientations) when I played YouTube clips in fullscreen mode.

I should point out that the internal display does actually go down to 1Hz, but has a lower pixel density thanks to its 2,076 x 2,152 resolution. I wasn’t ever blown away by either display, though, and merely found them perfunctory. They both go up to 2,700 nits of peak brightness, and are easy enough to read in sunlight, though the front screen can get up to 1,800 nits with HDR while the one inside only goes to 1,600 nits with HDR.

The Pixel 9 Pro Fold’s cameras and photography features

Google’s original foldable already had better cameras than Samsung’s latest, offering a longer optical zoom, sharper pictures and superior low-light performance. So though it’s slightly disappointing that the Pixel 9 Pro Fold doesn’t come with many hardware upgrades, what it does bring is still greater than the Z Fold 6. In fact, Sam says the Pixel 9 Pro Fold has the best cameras on any foldable you can buy in the US.

Google has kept the main sensor at 48 megapixels and upgraded the ultra-wide camera to enable macro focus. You’ll still find a 5x optical zoom on the telephoto camera, which is longer than the 3x option on Samsung’s Z Fold 6. What’s interesting is that with the Pixel 9 Pro Fold, Google had to tweak its camera hardware to “fit our unique ultra thin architecture,” which is a fairly impressive engineering feat.

When it came down to actual pictures, the Pixel consistently outshot the Z Fold 6, with Sam going as far as to say it’s “generally a tier level higher.” Colors are brighter and more accurate, and the telephoto hardware makes a noticeable difference in zoomed-in shots. That’s even before using Google’s Zoom Enhance software, too. Given Samsung has been using the same sensor for the main camera for the last three years, that doesn’t seem surprising, but it’s certainly a shame that those who shelled out $1,900 for the Z Fold 6 are stuck with poorer specs here. It’s strange too, considering Samsung’s main sensor is a higher-res 50MP.

It’s worth noting that Google’s primary hardware update also gave the Pixel 9 Pro Fold more of an edge, since being able to use its ultra-wide camera as a macro shooter made its close-up shots better than Samsung’s. Plus, Google continues to lead in low-light photography, producing sharper, more vibrant and better exposed images than the Z Fold 6.

In fact, software is where the Pixel cameras continue to shine. Google added new features like Add Me and Made You Look this year, with the latter being an exclusive to the Pro Fold. Makes sense, since that uses the internal and external screens. While you have the camera app open on the inside, tapping an icon above the shutter button lets you choose between dual screen, rear camera selfie or Made You Look. Selecting the last one brings up four options of different cartoon animations, and the respective character appears on the outside display. The chicken, or fish, or blob will dance around and make noises to get the attention of your subject. This is meant to work predominantly on children, though I imagine it’ll also pique the curiosity of cats and dogs. I tried it out mostly on adults, and got a slew of pictures of my friends looking incredulously at the camera. Basically this works for people aged one and up!

When you’re ready to edit your pictures, you’ll find the same suite of tools that are on the Pixel 9 Pro. That means things like Magic Editor, Reimagine and Autoframe are also available to spruce up your shots. I won’t retread ground we already covered in that review, but like we mentioned before, these generative-AI features are somewhat effective but occasionally problematic. I like using it to create more bushes or greenery in the background so I can center my friends in a candid photo, but find it concerning that Reimagine could be used to add “wrecks, disasters and corpses” to pictures, according to The Verge.

If you can stay away from the problematic AI tools, though, it’s heartening to see that the Pixel 9 Pro Fold can deliver photos that are as good as the ones I got from my iPhone 15 Pro Max. After all, you’re paying $1,800, you should be getting flagship-level cameras.

Performance and in use

Neither Sam nor I have had more than a week with the Pixel 9 Pro Fold, so it’s a little too early to talk about longterm performance and daily use. In general, though, so far we’ve noticed the new Fold runs smoothly and coolly, just like the other Pixel 9 Pros. That’s largely thanks to the Tensor G4 processor and built-in vapor chamber, and of course, maybe I just haven’t had the Fold long enough but it never got too warm.

I enjoyed watching YouTube with Threads open next to it on the internal screen, and the larger canvas also made Instagram pictures easier to scrutinize. I wish more apps were compatible with the bigger format, though, since my recent favorite games like Fruit Merge don’t expand to the full width and instead sit in the middle, flanked by two bars of empty space.

It’s also strange that flexing the screen, which is supposed to automatically switch compatible apps into a half-and-half layout, only works in landscape mode. That means if you open YouTube, bend the Pixel 9 Pro Fold slightly and flip it so the rear camera is on the top left corner, you’ll see videos take up the top half of the display. The bottom portion is where the title, description, comments and other videos sit.

This layout is intuitive, and makes sense in the landscape orientation where the clip you’re watching is propped up for easier viewing. I just wish there was an equivalent when you’re holding the Fold in portrait mode that would make the comments take up the right half of the display instead of the awkward column it currently uses.

Sam’s experience with the Galaxy Z Fold 6 leads him to find Samsung’s taskbar “a touch better for power users,” since you can set it to always stick around no matter what app you’re on. This makes it easier to launch apps in splitscreen or just jump between tasks. It’s also worth noting that Google doesn’t support stylus input, while Samsung does, and the latter’s DeX multitasking software is handy for productivity. The Pixel Fold doesn’t have such an interface where apps appear in floating windows, though I do like when compatible apps display extra columns or sidebars when they’re on the bigger screen.

Still, these are generally minor quibbles that feel easy enough to solve with software updates you might receive over time. If you’re not a power user or itching to use a stylus with your foldable, the Pixel 9 Pro Fold is a solid option over the Galaxy Z Fold 6.

The Pixel 9 Pro Fold’s battery life

The Pixel 9 series has been delivering seriously good results on our video rundown battery test and the Pixel 9 Pro Fold is no exception. When running on just the external display, the Fold clocked 27 hours and 9 minutes, which is basically the same as what the standard Pixel 9 got. When using just the interior screen, the Fold lasted 23 hours and 22 minutes, which is impressive for how much larger the panel is.

Those numbers are about two to three hours better than the Galaxy Z Fold 6, which notched 25 hours and 19 minutes when folded and 20:07 when open. The new Pixel Fold also beat its predecessor and the OnePlus Open, as neither of those even passed the 20-hour mark on our test.

Wrap-up

Although the Pixel 9 Pro Fold is only Google’s second foldable device, it’s already come a long way. It both looks and feels better than before, with a size and shape that is more similar to a standard phone when closed. When open, the device is easy to hold and provides a roomier canvas for light multitasking and gaming. Plus, compared to its main competition in the US, the Pixel Fold 2 (spiritually anyway) has a superior camera game and longer battery life. It’s also $100 cheaper than the Galaxy Z Fold 6, though it’s still pretty pricey at $1,800.

Google’s foldable line still has some quirks to work out, but that’s all part of growing up. For a device that’s only been around for two generations, the Pixel 9 Pro Fold is a solid foldable for anyone looking to dip their toe into flexible phones that can double as tablets.
