Samsung Galaxy S23 Ultra review: Samsung is nigh untouchable

Samsung Galaxy S23 Ultra in a nutshell

The Samsung Galaxy S23 Ultra has been available in most regions since February 17, 2023. It arrives in three memory configurations of 8/256 GB, 12/512 GB, and 12 GB/1 TB, retailing for $1,199.99, $1,379.99, and $1,619.99, respectively.

On paper, the Galaxy S23 Ultra delivered almost nothing new compared to the Galaxy S22 Ultra. I was even of a similar opinion during my hands-on session. However, after putting it through the paces in this comprehensive review, I found the Galaxy S23 Ultra to be a real winner.

Design

The Galaxy S23 Ultra carried over the same design language from last year's Galaxy S22 Ultra, which itself share cues from the last Galaxy Note 20, sporting angles and a slot for the S Pen.

What I liked:

• Aluminum frame and Gorilla Glass Victus 2 in front and at the back
• Integrated S Pen still works brilliantly
• IP68 certified

What I disliked:

• Iffy camera module (totally subjective)
• No 3.5mm audio jack
• Similiar design to last year's model

The Samsung Galaxy S23 Ultra has almost no noticeable changes in terms of design compared to the Galaxy S22 Ultra.

The Galaxy S23 Ultra comes in four colors: Phantom Black, Cream, Green, and Lavender. The glass back is protected by Corning's new Gorilla Glass Victus 2, as is the screen. The frame is made of aluminum and the smartphone is IP68 certified for both water and dust resistance.

On the bottom edge, we can see the S Pen slotted in nicely, just like in its predecessor from last year. It does seem as though Samsung did not really bother with the design, but then again, if it ain't broke, why fix it?

Screen

The screen of the Galaxy S23 Ultra has not changed much compared to the last year's model. We find a 6.8-inch AMOLED slab with curved edges that are compatible with HDR10+ and a maximum refresh rate of 120 Hz.

What I liked:

• Good brightness just like before
• The QHD+/120 Hz combo still works well
• Screen is slightly less curved

What I disliked:

• -

We, therefore, find a very similar, if not identical, panel to last year's Galaxy S22 Ultra. The QHD+ resolution of 3088 × 1440 p has not changed, and neither has the adaptive refresh rate of 1 to 120 Hz using LTPO 2.0 technology.

The curved edges of the Galaxy S23 Ultra's screen won't be to everyone's taste. Samsung seemed to have anticipated this by reducing the angle. The flat surface of the slab would therefore be slightly wider than on the previous model. It's just a tiny change, but you can see it when you hold the S22 Ultra and S23 Ultra side by side.

The screen has a punch-hole that is centered at the top. The idea of a hidden camera under the screen remains the prerogative of Samsung's foldable smartphones. Considering the loss of image quality that this technology brings with it, maybe it's all for the best.

Interface/OS

The Samsung Galaxy S23 Ultra runs on One UI 5.1, which is the latest skin from Samsung that is based on Android 13. Among the new features are Modes and Routines.

What I liked:

• 4 Android updates + 5 years of security updates
• A Focus mode like on iOS with Modes and Routines
• An extremely fluid and beautiful user interface

What I disliked:

• Not many exclusive features (maybe that's a good thing)
• Plenty of bloatware

I think One UI is becoming a more and more beautiful interface. On the Galaxy S23 Ultra, everything is much smoother, especially the animations.

I also loved discovering Samsung's super intuitive multitasking features. Being able to switch to split screen by swiping up with two fingers is one such example.

Swiping from a top corner of the screen to switch an open application to windowed mode is also a very nice touch (pun intended!).

I also like the stacked widgets just like on iOS. Being able to store multiple widgets in a single location opens up a lot of possibilities for customizing your home screen.

Among the most notable new features, I would like to specially mention the Routines and Modes functions. With Routines, you can automate a series of actions on your smartphone based to your activity. Basically, it works like the routines of your connected objects in your smart home.

You can save these different routines and associate them with Modes (sleep, sport, work) to switch from one mode to another and apply the corresponding routines. For power users or digital detox enthusiasts, this could be very relevant.

When it comes to the S Pen, Samsung didn't introduce anything new but it's still a pleasure to use. It's hard to live without it for taking notes, capturing screenshots, or photo editing.

Let's talk about photo editing. Samsung offers some options in its Gallery that I found to be rather useful. The fact that you can "remaster" a failed photo is pretty cool. And it's even cooler when doing so actually worked!

Because I'm starting to turn this review into a 500-page treatise on One UI, I'll just conclude with the "magic eraser" feature that allows you to erase unwanted elements from a photo. Personally, I think it worked pretty well. But I can't say that it stacks up well against Apple's and Google's solutions.

Performance

For the very first time in Europe, the Galaxy S23 Ultra is equipped with Qualcomm's Snapdragon 8 Gen 2 SoC. This is great news for those of us outside of the US, as Samsung previously included its less powerful Exynos chips on such regions.

What I liked:

• Big performance gain of the SD 8 Gen 2 compared to last year's Exynos 2200
• Progressive thermal throttling
• Up to 1TB of UFS 4.0 storage and 12GB of LPDDR5X RAM

What I disliked:

• -

When it comes to benchmarks, we obtained scores consistent with other Snapdragon 8 Gen 2-powered smartphones. At the same time, there aren't too many of those just yet. It did perform better than the OnePlus 11 5G (review).

It is, however, less stable than the Xiaomi 13 Pro (review) on the 3DMark Wild Life Stress Test benchmark that simulated 20 minutes of intensive gaming use. But this is certainly due to the fact that Xiaomi operates with close to no thermal throttling, which will eventually result in overheating issues.

However, the Galaxy S23 Ultra does not overheat at all. It never exceeded 45° during our benchmarking efforts. This was made possible courtesy of its thermal throttling which happened in a progressive manner. As soon as the temperature rose, the smartphone pulled the handbrake with the dexterity of the late, venerable Ken Block. Everything was done smoothly and the framerate stabilized quickly.

In everyday use, we can obviously run all imaginable games from the Play Store without missing a beat. I was actually able to run Call of Duty Mobile and Sky Children of Light at 120 FPS. Unfortunately, I do not have any video to show you because the screen recorder automatically drops the framerate to 60 FPS max. So you'll have to make do with the screenshots below.

I was also able to run Fortnite at a constant 60 FPS with the graphics turned up. Even Genshin Impact, a game that eats up a ton of RAM, ran at 60 FPS without kicking up a fuss. And at no time did the smartphone burn my hands. It's really night and day compared to the Galaxy S22 Ultra.

Photo quality

The Galaxy S23 Ultra embeds a quadruple camera module that is spearheaded by its new 200 MP photo sensor. The latter is mated to a classic 12 MP ultra wide-angle lens and two telephoto lenses at 10 MP each. Samsung has also finally improved its selfie camera by throwing in a 12 MP lens.

What I liked:

• Most versatile camera module on the market
• The main lens of 200 MP works great during the day and at night
• 3x and 10x zoom performs well
• Great progress in low light situations

What I disliked:

• Portrait mode is a bit disappointing for this price range
• No big improvements when it comes to selfies
• Focus is still a bit iffy (but I'm kidding)

The camera module of the Galaxy S23 Ultra perfectly illustrated the user experience with this smartphone. On paper, almost nothing has changed. But when you step away from the specifications and actually use the cameras, you can see the difference right away.

The photo quality of the Galaxy S23 Ultra is almost impeccable during the day

Let's begin with the most obvious difference: the main lens with this new 200 MP Isocell HP2 sensor. I was lucky enough to have a few hours of good weather this week. And I found all my daytime shots to be excellent. The level of detail captured is impressive. Well, the colors are still a bit saturated, but that has always been the case with Samsung, and I like this colorimetry.

The dynamic range management is excellent. Even in complex shots, we have a balanced contrast. The 12 MP ultra-wide angle also does very well. Edge distortion is well-contained and I didn't notice any major color inconsistencies compared to the rendering of the main lens.

The portrait mode of the Galaxy S23 Ultra

I just found the portrait mode to be not as good as the Huawei Mate 50 Pro (review) and the iPhone 14 Pro (review). The cropping is not always clean and the focus tends to run, especially with non-human subjects.

The two telephoto lenses with optical zoom of the Galaxy S23 Ultra are... ultra-efficient

The other great point of the Galaxy S23 Ultra is its zoom capability. We have two focal lengths to operate at 3x and 10x native zooms. There is nothing much to say here, apart from the sharpness being there alongside the right colors. I noticed some unavoidable artifacts when switching to 30x zoom but I was also very pleasantly surprised by the results at times.

Samsung can't be beaten when it comes to the versatility of its camera module. It's just extremely cool to have so many shooting possibilities without having to physically move. The camera app still offers some degree of assistance to help you aim when you go beyond the 20x zoom, which still works great, by the way.

The Galaxy S23 Ultra is a strong performer at night

At night, the Galaxy S23 Ultra offers an automatic night mode. It will activate itself when it detects the surrounding light conditions that require it. And with the main lens, I find that Samsung managed to capture the scenes very well, looking rather natural.

There is not too much noise or abuse of digital smoothing going on there. Of course, things begin to go downhill with the ultra-wide angle lens, as usual. The 3x zoom remained quite usable most of the time. The Galaxy S23 Ultra also has a dedicated night mode, but I found it to be too unnatural and overexposed the scene too much.

In any case, we can see a clear difference, and there is surefire progress in low light conditions compared to the Galaxy S22 Ultra which was a bit deficient on this point, as I noted in my review.

Battery life

The Samsung Galaxy S23 Ultra features a massive 5,000 mAh battery. This is the same battery capacity as last year while the Galaxy S23 and Galaxy S23 Plus benefited from larger batteries compared to their predecessors.

What I liked:

• Excellent battery life

What I disliked:

• Charger is not included in the box
• No improvement when it comes to fast charging

The Samsung Galaxy S23 Ultra is ultra-durable when it comes to battery life. I put it through the PCMark Work 3.0 benchmark. I set the display to QHD+ resolution, refresh rate to 120 Hz, and brightness to 200 nits. Despite all that, the Galaxy S23 Ultra lasted for 13:09 before dropping below the 20% battery life notch.

I'm going to do an additional test tonight with the screen in Full HD+ and at 60 Hz. I'm sure the Galaxy S23 Ultra can hit 15 or even 16 hours of battery life.

I just think it's a shame that Samsung still doesn't have the desire to do better in terms of fast charging. As you can see, you'll have to deal with 45-watt wired charging and 10-watt wireless charging again this year. The 4.5-watt wireless reverse charging is still part of the ensemble, too.

And like last year, the charger is not included in the box since it is well known that selling chargers separately in dedicated packaging helps save the planet.

There is one saving grace though, at least Samsung doesn't use proprietary charging technology means that you can use any charger that is compatible with the USB PD 3.0 standard.
