Samsung has not one but two lavishly expensive 2023 flagship smartphones: the Galaxy S23 Ultra and the Galaxy Z Fold 5. If you can stomach the sky-high prices, these devices offer stellar build quality and long software support, but they offer very different experiences. So, which one should you get? Let’s see how Samsung’s best phones stack up.
It’s also worth noting that the Galaxy S23 Ultra has been superseded by the Galaxy S24 Ultra, so check out our Galaxy S23 Ultra vs S24 Ultra comparison to learn more.
Samsung Galaxy Z Fold 5 vs Samsung Galaxy S23 Ultra: At a glance
The Galaxy Z Fold 5 is the most expensive Samsung smartphone, but that’s because it’s a foldable. There’s a tall, narrow display on the outside and a larger foldable one inside. The Galaxy S23 Ultra is cheaper (though still expensive) and shaped like a traditional smartphone — a big one.

On the inside, these physically different devices have a lot in common. They have the latest Qualcomm Snapdragon 8 Gen 2 chip, which has been tweaked by Qualcomm for Samsung. It’s got a higher clock speed than you’ll see in other 2023 Snapdragon phones, but thermal performance matters more than a small clock bump. In our testing, the Z Fold 5 throttles more heavily under sustained load than the S23 Ultra, losing almost half its initial speed. The S23 Ultra only drops about 20%, which is more in line with other phones.
The Galaxy S23 Ultra is shaped like a (very large) traditional smartphone, with a 6.8-inch 1,440 x 3,088 AMOLED screen, but the Z Fold 5 has two AMOLEDs, a 6.2-inch (904 x 2,316) on the front and a 7.6-inch (1,812 x 2,176) folding display inside. All these panels support 120Hz refresh and have enough brightness to be fully readable outdoors; both Android phones can boost to 1,750 nits in direct sunlight.

Since the S23 Ultra doesn’t fold, there’s no hinge to worry about. Don’t stress too much about the Z Fold 5’s hinge, though. Samsung has been refining its hinge design for five generations, and the new “Flex Hinge†is the best one yet. It folds up flat, and the mechanism feels very solid. When unfolded, the Z Fold 5 feels every bit as stable as a big phone like the S23 Ultra, but it offers even more screen real estate.
Both phones have Samsung's multi-window features for floating apps and split-screening, but the larger display on the Fold 5 lets you split three apps at once instead of just two.
The Samsung Galaxy S23 Ultra and Galaxy Z Fold 5 both support Samsung’s S Pen, but the S23 Ultra comes with a pen — that’s an add-on purchase for the Z Fold 5. There’s enough space in the S23 Ultra for the pen to stow inside, making it easy to carry around. You’ll need a Z Fold 5 case with a garage to keep the S Pen handy. You’re also limited to the main foldable screen for doodling as the cover display does not have S Pen functionality.

The Galaxy S23 Ultra has 8GB of RAM in the base model, which is sufficient, but you can get 12GB in upgraded versions. That’s what you get in the base model Z Fold 5, but it needs that additional RAM for multitasking. Both phones have Samsung’s multi-window features for floating apps and split-screening, but the larger display on the Fold 5 lets you split three apps at once instead of just two. Both phones have the same 256GB, 512GB, and 1TB storage options with no SD card slot.
Aside from the multitasking optimizations on the foldable, both these devices have essentially the same software experience, even if some large-screen apps suit the Z Fold 5 a little better. They run Android 13 with Samsung’s One UI 4.1 interface. There are handy shortcuts to stylus-friendly apps, multitasking favorites, and you get full Material You theming.

Both the Samsung Galaxy S23 Ultra and Galaxy Z Fold 5 are very large phones, but the Fold 5 will stretch even spacious pockets. The S23 Ultra has the kind of heft you’d expect from a high-end smartphone, measuring 78mm wide and 163mm tall. The edges curve to make it a bit easier to hold, and it’s a reasonable 8.9mm thick. The Z Fold 5 is slimmer than past foldables, but it’s still in a different league than the S23 Ultra.
The Z Fold 5 measures 67mm wide and 154mm tall when folded, but the real issue is the 13.4mm thickness. It’ll be folded in this brick-like conformation when you drop it in a pocket or bag. Naturally, the footprint gets a lot bigger when you open the Z Fold 5. The device is 6.1mm thick when open, and the width goes to 129mm.
These phones will create unsightly lines in your nice, crisp trousers and ratty jeans alike. That said, the Fold 5 is much more uncomfortable to haul around, and it’s more ungainly when you fish it out of your pocket, which makes it easier to drop. And woe is you who drops an $1,800 glass sandwich. The Fold is also heavy enough that you might be instantly put off. It tips the scales at 253g, but the S23 Ultra is only modestly lighter at 234g.

Looking past the form factors, the camera array is the biggest hardware difference between these phones. Space is at a premium in foldables, so it’s a camera phone with some compromises. The Samsung Galaxy Z Fold 5 sports a triple camera system with a 50MP primary, 12MP ultrawide, and 10MP telephoto (3x). This setup is virtually identical to what you get on the Galaxy S23 and S23 Plus.
In addition to the Galaxy Z Fold 5 samples below, we have uploaded the full set to Google Drive.
Despite costing so much less, we found the Galaxy S23 Ultra to have a much more capable camera system. There are four sensors on the back, including a 200MP primary, a 12MP ultrawide, a 10MP telephoto (3x), and another 10MP telephoto (10x). Even where the megapixel counts line up (e.g. the ultrawide), the S23 Ultra has larger, brighter sensors.
We have some Galaxy S23 Ultra samples from our review below, plus a full set right here.
The primary cameras output at similar 12MP resolutions because the default shooting mode uses pixel binning. Essentially, this approach to mobile photography merges blocks of physical pixels into larger virtual pixels. This allows the sensor to collect more light for brighter images and faster captures. The photos we’ve gotten from the Z Fold 5 are not bad — Samsung’s photo processing is almost as good as Google’s these days. However, the S23 Ultra’s hardware advantage shows, particularly in dimly lit environments.
There’s one other notable camera difference. While the S23 Ultra only has one 12MP selfie camera, the Z Fold 5 has two. There’s a 10MP sensor in a cut-out in the cover display and a 4MP shooter under the internal folding OLED. That 4MP module is passable for video calls but doesn’t take good photos. The reason; it’s an under-display camera — a matrix of pixels covers it when not in use. That part of the screen looks a bit fuzzy, but it’s not something you notice after a while.

The space constraints of foldables also affect the battery life of the Galaxy Z Fold 5. Even with the S Pen inside, Samsung found more room for the battery inside the S23 Ultra. This phone has a 5,000mAh cell, which should last you over a day, even with heavy use. The Z Fold 5 only has 4,400mAh of juice, and the large foldable screen burns through that. You can get a day of use out of the Z Fold 5, but you have to be more mindful of your usage.

Samsung’s phones are not known for having the best charging speeds, but this is another place where foldables fall behind. The Galaxy S23 Ultra has a respectable 45W max speed (65% in 30 minutes in our testing), although you’ll need a compatible charger to hit that number. The Galaxy Z Fold 5 has a maximum of just 25W (about 50% in 30 minutes in our testing). Both phones support the same 15W maximum wireless charging speed and 4.5W reverse power share.
Samsung Galaxy Z Fold 5 vs Samsung Galaxy S23 Ultra: Price
Samsung Galaxy S23 Ultra (256/8GB): $1,199.99
Samsung Galaxy S23 Ultra (512/12GB): $1,379.99

Samsung Galaxy Z Fold 5 (512/12GB): $1,919.99
Samsung Galaxy Z Fold 5 (1TB/12GB): $2,159.99
There’s no way around it — these are extremely expensive phones. Even if you pick one up on a carrier installment plan, the S23 Ultra could add as much as $50 per month to your bill. And the Galaxy Z Fold 5? Plan on up to $75 more each billing cycle. The Galaxy S23 Ultra starts at $1,199.99 with 356GB of storage and 8GB of RAM. Meanwhile, the Galaxy Z Fold 5 is $1,799.99, with 256GB of storage and 12GB of RAM.
Luckily, Samsung does offer generous trade-in values when you purchase one of its high-end smartphones. Even a phone from several years ago can drop hundreds of dollars from the final price.

If you’re looking seriously at purchasing either of these phones, you’re already committed to dropping a lot of money. The Galaxy S23 Ultra is one of the most expensive smartphones in the world, with a starting price of $1,200. And then the Galaxy Z Fold 5 is another $600 on top of that. If your eyes bulged at that split, the $1,800 Z Fold 5 is probably not for you.
The extra six hundred smackers for the Z Fold 5 gets you an unparalleled multitasking experience — it’s really a small Android tablet that fits in your pocket. For basic smartphone tasks like browsing the web, playing games, and sending messages, the S23 Ultra is more than enough. It doesn’t throttle as much as the Z Fold 5 under load, and the camera system is better. So, it’s the best choice for most Samsung fans. If you’re like me and can’t resist the foldable future, the Z Fold 5 is the best in that category.
