Samsung Galaxy S23 Ultra specs — everything you need to know
All the key specs for the Galaxy S23 Ultra, and what they mean
The Samsung Galaxy S23 Ultra specs that just got announced make it look like a seriously powerful phone, and that it's thoroughly deserving of its spot at the top of the Galaxy S23 pile.
Thought much of the Galaxy S23 Ultra's characteristics are shared by either the outgoing Galaxy S22 Ultra, or the cheaper Galaxy S23 models, its blend of power and state-of-the-art features will make it one of the most impressive phones on the market once it goes on sale. The only remaining question is if these specs add up to a good phone, but we'll let you know the answer after we've done some more testing post-Galaxy Unpacked.
For now though, here's the Samsung Galaxy S23 Ultra specs, and some explanation if you're uncertain what any of these numbers and names will mean for your smartphone usage.
Galaxy S23 preorder: up to $100 credit @ Samsung
Up to $100 credit! Samsung is one of the best sites for Galaxy S23 preorders. Reserve your Galaxy S23 preorder via Samsung and you'll get up to a $100 Samsung credit. You'll get a $50 credit when you reserve one device or a $100 credit if you reserve two devices. (It's likely Samsung will also announce a new Galaxy Book). This is a no commitment pre-order. All you need to do is provide your name and e-mail address to reserve. Once you pre-order, you'll receive your credit.

Samsung Galaxy S23 Ultra specs: design
Row 0 - Cell 0 | Row 0 - Cell 1 |
Size | 163.4 x 78.1 x 8.9mm (6.43 x 3.07 x 0.35 inches) |
Weight | 233g (8.25 ounces) |
Water/dust resistance | IP68 |
Colors | Phantom Black, Cream, Green and Lavender |
Materials | Gorilla Glass Victus 2 (front/back), Armor Aluminum (sides) |
According to its official measurements, the Galaxy S23 Ultra is a little skinnier but also a touch heavier than the Galaxy S22 Ultra that precedes it. The changes are only minimal, so are unlikely to impact your buying decision.
Like Samsung's other flagship phones, the Galaxy S23 Ultra is IP68 dust/water resistance rated, the gold standard for smartphones. There's no better guarantee your phone will keep water drops or dust particles away from its sensitive components unless you go for a specific ultra-durable phone.
To protect the phone from scratches and drop damage, the Galaxy S23 Ultra is clad in Gorilla Glass Victus 2, tougher than the Gorilla Glass Victus Plus used by the Galaxy S232 Ultra. The S23 Ultra also uses an Armor Aluminum frame like the S22 Ultra to protect the edges from harm.

Lastly, it's there are four color options for the Galaxy S23 Ultra, which are the same as the options for the S23 and S23 Plus too: Phantom Black, Cream, Green and Lavender. You could get black, white or green on the Galaxy S22 Ultra last year (although likely slightly different hues compared to the S23 Ultra), but the new purple option replaces the S22 Ultra's burgundy option.
Samsung Galaxy S23 Ultra specs: display
Row 0 - Cell 0 | Row 0 - Cell 1 |
Display size and type | 6.8-inch, AMOLED with curved edges |
Resolution | QHD, 3088 x 1440 |
Refresh rate | 1 - 120Hz adaptive |
Max brightness | 1,750 nits |
There are no big changes to the Galaxy S23 Ultra's display compared to last year. It's still a large display with curved left and right edges (although flatter overall), a QHD resolution and an adaptive refresh rate that can slide anywhere between 1Hz and 120Hz to balance both smooth and efficient screen performance.
The maximum display brightness of 1,750 nits is the same as Samsung claimed for the Galaxy S22 Ultra last year. However, the S22 Ultra couldn't quite crack 1,000 nits of maximum brightness in our testing, so hopefully the S23 Ultra can get closer to Samsung's promised brightness, if not match up to it. After all, brighter displays mean it's easier to read your phone even if it's really sunny outside.
Samsung Galaxy S23 Ultra specs: cameras
Row 0 - Cell 0 | Row 0 - Cell 1 |
Main camera | 200MP, f/1.7, 1/1.3 inches, 0.6µm pixels |
Ultrawide camera | 12MP, f/2.2, 1/2.55 inches, 1.4µm pixels |
Telephoto camera #1 | 10MP, 3x optical zoom, f/2.4, 1/3.52 inches, 1.12µm pixels |
Telephoto camera #2 | 10MP, 10x optical zoom, f/4.9, 1/3.52 inches, 1.12µm pixels |
Selfie camera | 12MP, f/2.2, TBC inches, TBC pixels |
Video recording | 8K at 30fps, 4K at 60fps, 1080p at 240fps, 720p at 960fps |
Samsung added a 200MP main camera to the Galaxy S23 Ultra, which is significantly higher resolution than the Galaxy S22 Ultra's 108MP camera, and basically every other main camera on a smartphone you can buy right now.
While we won't know exactly what it's capable of until we test it, it looks at first flush to be a versatile sensor, capable of capturing maximum detail at 200MP, better light and color at a pixel-binned 12.5MP, and a mix of the two at 50MP.
The other new camera is a 12MP front-facing camera, a lower resolution than last year's 40MP front camera. This sounds like a downgrade, but we're impressed with its shots so far, so hopefully it's actually a boost to the Galaxy S23 Ultra's selfie game.
The rest of the Galaxy S23 Ultra's sensors, the 12MP ultrawide camera, the 10MP 3x telephoto and 10MP 10x telephoto, are effectively (if not) the same as the Galaxy S22 Ultra. Samsung has improved its Nightography low-light mode, enhanced things like autofocus and OIS (optical image stabilization) and added new features like Astro Hyperlapse too, which its previous phones couldn't manage.
For video, we got a bump the Galaxy S23 Ultra's frame rate at its maximum 8K resolution, from 24fps as the Galaxy S22 Ultra manages to 30fps. 4K resolution and below keep their existing refresh rates, including slo-mo options for 1080p and 720p.
Samsung Galaxy S23 Ultra specs: chipset and memory
Row 0 - Cell 0 | Row 0 - Cell 1 |
Chipset | Snapdragon 8 Gen 2 Mobile Platform for Galaxy (Octa-core) |
Chipset cores and frequency | 1 x Cortex-X3 (3.36GHz), 2 x Cortex-A715 (2.8 GHz), 2 x Cortex-A710 (2.8 GHz) & 3 x Cortex-A510 (2.0 GHz) |
GPU | Adreno 740 |
RAM (type) | 8GB/12GB (LPDDR5) |
Storage (type) | 256GB, 512GB, 1TB (UFS 4.0) |
Samsung is going all-in on the Snapdragon 8 Gen 2 for the Galaxy S23 Ultra, rather than splitting models between Snapdragon and Exynos chips like it has in previous years.
The important change to look out for is that the chip is specifically a Snapdragon 8 Gen 2 Mobile Platform for Galaxy. This mouthful of a name translates to Samsung getting a custom, higher-performance version of the new chip that would in theory outperform other phones using the same silicon. You can see this in the rumored 3.36GHz speed for the most powerful Cortex-X3 core, which is a bit faster than the standard 3.2GHz speed of that core on a regular Snapdragon 8 Gen 2 chip.
For memory and storage, there are no changes from the Galaxy S22 Ultra. The basic Galaxy S23 Ultra comes with 8GB RAM and 256GB storage, but you can spec up to 12GB RAM and 1TB of storage if you pay enough.
The RAM and storage uses the LPDDR5 and UFS 4.0 standard. That's not quite the latest in RAM standards (that would be LPDDR5X), but UFS 4.0 is as up-to-date as you can get for flash storage. We may see phones launched later in the year outpace the Galaxy S23 Ultra for RAM speed, but in day-to-day use though, the S23 Ultra should feel nice and fast.
Samsung Galaxy S23 Ultra specs: battery and charging
Row 0 - Cell 0 | Row 0 - Cell 1 |
Battery capacity | 5,000 mAh |
Wired charging speed | 45W |
Wireless charging speed | 10W |
Just like the Galaxy S22 Ultra, the Galaxy S23 Ultra gets a 5,000 mAh battery, and supports up to 45W wired charging and 10W wireless charging.
We'll have our fingers crossed that with its new chipset and other refinements, the Galaxy S23 Ultra can manage a higher battery life score. The Galaxy S22 Ultra didn't score well in our battery life test, particularly when in fully adaptive mode.
Samsung Galaxy S23 Ultra specs: software and special features
Row 0 - Cell 0 | Row 0 - Cell 1 |
Software | Android 13 with One UI 5.1 |
Special features | Built-in S Pen stylus |
Samsung debuted its new One UI 5.1 software, based on Android 13, on the Galaxy S23 series. You should also get four years of software updates on any Galaxy S23, including the Galaxy S23 Ultra, keeping you up to date with new software features for some time to come.
The most unique thing about the Galaxy S23 Ultra, even considering its other class-leading features, is its included S Pen stylus, something it inherited from the Galaxy S22 Ultra. Few other phones come with styluses these days, so anyone who likes making hand-written notes or drawings is best sticking with Samsung.
