Galaxy S23 review: its value has dropped
Galaxy S23 Intro
The Galaxy S23 series is now two years old, and it's in the hands of plenty of users. The second-hand market is flooded with these devices, and retailers often offer them at discounted prices. So, if you're considering picking one up in 2025, our full review has you covered with everything you need to know!
The Galaxy S23 is a bit of a unique flagship. It arrived at a time when UFS 4.0, a faster storage standard, was just starting to roll out. This new chip was twice as fast as the previous UFS 3.1, but UFS 4.0 only came with the 256GB model and above. The 128GB version of the S23 still had UFS 3.1, so if you're eyeing one, make sure to go for the 256GB model to get the best performance. The extra $60 for the upgrade back when it launched was absolutely worth it—and we think it still is today.
Here’s what the base Galaxy S23 brings to the table:
It features the Qualcomm Snapdragon 8 Gen 2 "Made for Galaxy", which was a first for the S23 series. Samsung and Qualcomm worked together on the chipset, and the special edition designed for Galaxy devices is slightly overclocked, delivering that extra performance boost when you need it, especially for benchmark scores.
We also got a facelift, camera improvements, and a few additional upgrades both inside and out. Let’s dive into all the details of the Galaxy S23!
Despite being two years old, the Galaxy S23 remains a solid option. It has two more years of software support to look forward to, and its hardware and design are still top-notch.

Specifically about the cameras, we have put each one through our new in-depth camera testing procedure and given it a score, which you can find in this review's 'Camera' section. If you want to find out more about how we rate each camera check out our PhoneArena Camera Score benchmark page.
As you can see above, the Galaxy S23 total review score is lower than you might expect. That is not because the phone is flawed in some unexpected ways, but because we have implemented a new rating system at PhoneArena that gives readers a better idea of the performance of a phone across different categories. Remember to look at the scores and compare them to the average for the class, and we believe you will find these scores tremendously useful.

Galaxy S23 Unboxing
The current standard is to get a thin box with just the phone and data cable inside. Some booklets and a SIM ejector tool, too, of course.
The box of the Galaxy S23 is made entirely out of recycled paper, as Samsung is looking to green-ify its product lines as much as possible. The Galaxy S23 itself is built with 20% recycled plastic, 22% recycled glass — where possible.
Galaxy S23 Specs
The next Samsung flagship
Now that the cat is out of the bag, we have the official specs of the Galaxy S23. Here goes:
| Specs | Samsung Galaxy S23 |
|---|---|
| Size and Weight | 5.76 x 2.79 x 0.30 inches (146 x 70.9 x 7.6 mm) |
| Display | 6.1" AMOLED, 120 Hz, 1080x2340 pixels, 1,750 nits peak |
| Processor | Qualcomm Snapdragon 8 Gen 2 for Galaxy, 3.36 GHz |
| RAM | 8 GB |
| Storage | 128 GB / 256 GB |
| Software | One UI 5.1 / Android 13 |
| Cameras | 50 MP wide camera, F1.8 12 MP ultra-wide camera, F2.2 10 MP 3X telephoto camera, F2.4 12 MP selfie, F2.2 |
| Battery Size | 3,900 mAh |
| Charging Speeds | 25 W cable, 15 W wireless |
| Price | last MSRP $699, now discontinued |
The S23 looks like a proper evolution of the S22. The battery is up by 200 mAh, the design has been touched up a bit, the selfie camera gets a bump to 12 MP over last year's 10 MP. The main camera module looks like a rehash of the S22 series, but this time around — we get 8K video at 30 FPS as an option (it was locked to 24 FPS before).
The Snapdragon 8 Gen 2 here is a special edition — branded Snapdragon 8 Gen 2 Mobile Platform for Galaxy. Not only is it clocked to a slightly higher tick rate, it also helps with the camera trickery behind the curtains. The processor's Semantic Segmentation intelligently identifies objects, faces, body parts, what's in the foreground and what's in the background, to achieve much more convincing post processing effects. On the Galaxy, it can do that with the selfie camera as well!
It’s not all sunshine and rainbows, though. If you choose to buy the entry level Galaxy S23 128 GB, you will find that it is at a slight disadvantage to its sibling. This cheapest Galaxy S23 will come with a UFS 3.1 storage chip and LPDDR5 RAM. Any other Galaxy S23 — either the upgraded 256 GB option, or any Galaxy S23+ and Galaxy S23 Ultra — get a much faster UFS 4.0 and LPDDR5X RAM chips.
Here's another incentive to upgrade — out of the box, the system of the Galaxy S23 already takes up to 40 GB of storage (curiously, S23+ and S23 Ultra software takes up to 60 GB). This means that, if you buy the entry level 128 GB, you will quickly be running out of storage. This, and the speed upgrade, is why we firmly recommend upgrading to the 256 GB model, though this may be impossible in 2025.
The good news is that a storage upgrade is only $60, so it's not a huge deal. At this point, we kind of wonder if the 128 GB version only exists so Samsung could say the phone "starts from $799".
Galaxy S23 Models
We are looking at the base Galaxy S23 here, but the family will include three devices — Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra, with the last one being the absolute beast... as is customary.
Typically, the non-Plus is the smallest member of the series. With a compact shape and a lowest cost, you could argue that the Galaxy S23 is the true flagship, as its expected to be the most mainstream-friendly phone.
Galaxy S23 Design & Colors
Classy design, subdued finishes

If you've been hoping for hot and vibrant colors on the Galaxy S23 — sorry. The official colors are Phantom Black, Cream (kind of beige), Green, and Lavender (purple-ish). They are quite subdued and earthy, keeping a low profile in an understated elegance.
As is customary, you can pick up exclusive colors from Samsung.com — this year, they are Lime and Graphite.
We'd say they go well with the new design of the S23 phones. Gone are the bold camera modules that are glued to the phone's frame and stick out from behind. Now, the back is entirely flat, with only the lens-protecting metal rings protruding out there.
So, yes, the phone will still rock if laid flat on a table — we can't have this classic ruined, now, can we? But the entire look of the Galaxy S23 series has been unified and they all kind of look like the S22 Ultra from last year.
The metal frame on the side is still flat-ish, with a slight arch to it, and the screen is entirely flat. No edge curves here.
This all works in tandem with a body that we can call compact… by 2023 standards, the Galaxy S23 is quite pocketable. If using a phone with one hand is a priority over media consumption, we’d put this phone on our list of suggestions.
Galaxy S23 Display
Samsung is on top of its AMOLED game. Bright, vivid, sharp, and beautiful screens that the company has been perfecting over the last decade. The Galaxy S23 keeps this up, but now turns the brightness up... way up. The tiny phone is capable of hitting 1,750 nits of peak brightness if needed. And you will definitely not need more than that, even under the scorching August sun.

It's still a 6.1-inch diagonal with an aspect ratio of around 19.5:9 maintaining a narrow and tall build. With an FHD resolution of 1080 x 2340, we get PPI ratio of around 425. That's pretty sharp — you won't be counting the pixels on this screen.
If we turn off the software optimizations, we can see the screen leans slightly towards the greenish tints. Surprisingly, the Galaxy S22 from last year had more accurate colors than the current S23, at least our test units did. However, when we use the phone as a daily driver, we have the Eye Comfort Shield feature always on — it adjusts color temperature based on time of day. And the cold tendencies of the panel are never an issue, if at all noticeable.
Galaxy S23 Camera
Your upgrade is in another castle
Unfortunately there's not much new to say about the Galaxy S23 camera. It's still a 50 MP main, 12 MP ultra-wide, and 10 MP telephoto combo like last year. Physically, they seem to be the same cameras, but the power of the Galaxy-edition Snapdragon 8 Gen 2 does change some things.
Ultra-wide
We do find the Galaxy S23 to be tuned for slightly warmer photos than the S22. Also, we couldn’t help noticing that it has a more powerful HDR, flattening out the high dynamics in a shot even more. It’s quite impressive, but at this point, some users might prefer the slightly more contrast-y looks from an S22, for example.
However, the Galaxy S23 also seems to deliver a bit more realistic colors — saturation seems to be dialed back by just a bit, but that’s enough to reign in those vibrant greens and neon skies that we’ve seen from Samsungs before.
The same calibration and rules apply for the ultra-wide camera.
Zoom and Portrait mode
While the Qualcomm Snapdragon 8 Gen 2 is supposed to have some insane subject separation for Portrait modes, we can’t really say we see any massive improvements here. That’s mostly because Samsung’s Portrait mode was already pretty good in that aspect. We would’ve liked to see a more convincing-looking background blur, or less smoothening on facial features. Gripes aside, it’s a pretty solid Portrait Mode.
As for zooming — the Galaxy S23 can only do up to 30x digital and it’s not great. You can say you have it… but you probably will never use it.
Selfies
The jump to a 12 MP selfie sensor is visible here with some impressive details in the shots — we see no abhorrent oversharpening, yet the details in the winter hat look so real, you can almost touch it!
The dynamics are also handled quite well and the Snapdragon Semantic Segmentation is also applied here for better portraits — this is the fist smartphone to use the Qualcomm tech for the selfie side.
We can now also record 8K video at up to 30 FPS, as opposed to being locked to 24 only. And we noticed quite the improvement in stabilization as well, despite the fact that this was an upgrade touted for the Galaxy S23 Ultra.
We have rigorously tested the camera on the Samsung Galaxy S23 and above you can see the results of those tests. We carefully measure the performance of all cameras in various test scenes, ranking the performance across important metrics like exposure, subject exposure, color accuracy, detail, artifacts and more. We do these tests for both photos and videos.

Galaxy S23 Performance & Benchmarks
Second generation of ultimate power

The new Snapdragon 8 Gen 2 Mobile Platform for Galaxy sounds very, very promising. We ran it through our benchmarks and it seems to be able to churn out stellar performance over longer periods — no doubt thanks to the help of the upgraded heat dissipation system of the Galaxy S23.
But life is not about benchmarks. And in real life, the Galaxy S23 is a pleasant performer. No hiccups, no stutters — the phone is smooth and responsive, and all “Go, go, go”. Despite the fact it’s kind of tiny to be the poweruser’s dream, it can definitely flex its proficiency if you choose to use the DeX suite for example (turns your phone into a desktop machine, bring your own monitor).
As we mentioned in the intro, it's worth hunting down the 256 GB variant of the Galaxy S23 because it comes with a UFS 4.0 chip, ensuring faster read and write speeds. It really opens the phone's performance up. The review unit we have in the office is, in fact, the 256 GB model.
Galaxy S23 OS / Android version
The latest Android build out there is Android 13 and that's what the Galaxy S23 is launching with. But you know the deal — Samsung likes to do its own stuff, so its Android phones have the elaborate One UI reskin — the latest one being One UI 5.1.
Samsung's software is full on features that completely change the way you interact with Android — easy split screen shortcuts, edge panels that you can pull in from the side for multi-tasking, and complete integration with Samsung's ecosystem with SmartThings Hub. Not to mention DeX, which can turn your phone into a mobile desktop machine, as long as you have an external monitor to work on.
It is also worth noting that Samsung has severely improved its software update game. New flagships now come out with the promise of 4 major Android updates, and 5 years of security patches. That means that the Galaxy S23 may launch with Android 13 but will end up with Android 17 down the line.
At least that's how we interpret Samsung's words, let's break it down just to be sure:
At least that's how we interpret Samsung's words, let's break it down just to be sure:
- Galaxy S23 launched with Android 13 in early 2023
- Update 1 - Android 14 in late 2023
- Update 2 - Android 15 in late 2024
- Update 3 - Android 16 in late 2025
- Update 4 - Android 17 in late 2026
- Galaxy S23 reaches end of 4-year promise in early 2027
- Galaxy S23 stops getting security updates in early 2028
Galaxy S23 Battery
A small bump in capacity
OK, so as rumored, we do get a 200 mAh increase in battery capacity — up to 3,900 mAh. There are two ways this could go — the extra 200 mAh may be there to balance out the demands of a more powerful Snapdragon 8 Gen 2, no difference in the end. Or, it could work in tandem with power efficiency in the Snapdragon 8 Gen 2 and deliver better battery life.
In any case, we are optimistic that we won't be seeing a drop in endurance compared to the Galaxy S22. So, 12 hours of constant browsing or 9-10 hours of mixed usage per day.
PhoneArena Battery Test Results:
And above, you can see just how well the Galaxy S23 performs in our in-house battery tests.
Galaxy S23 Audio Quality and Haptics
Ever since Samsung acquired AKG it has slowly and surely improved the sound of its mobile devices. The Galaxy S23, as is customary now, has a stereo setup with bottom driver and amped earpiece. They usually sound decent, but it seems that Samsung has done some upgrading. The Galaxy S23 speakers sound very nice — they can get decently loud, yet they are balanced and have a bit of thump behind them. We wouldn't mind listening to music from these while doing chores.
The haptics on the flagship Galaxy series, however, are excellent and the Galaxy S23 clicks with very pleasing feedback.
Galaxy S23 Competitors
Obviously, the iPhone 14 will be a pulling force that will threaten the Galaxy S23's success. However, it does have shortcomings — Apple will only give you a 60 Hz screen and two cameras with the base iPhone 14.
The Galaxy S23 will come out swinging with a 120 Hz screen and a full trio of cameras, there to please fans of portraits and zooming.
But what about on the Android side? Well, Google's latest Pixel 7 duo is very tempting. The base Pixel 7 costs $600 and is an absolute bargain. And the Pixel 7 Pro is only slightly more expensive than the Galaxy S23 — an extra $100 and you get a bigger screen and the premium Google Assistant experience.
But Samsung has been in the game for a while now and has built a robust ecosystem around its phones. The feature-rich One UI, DeX, SmartThings, the Galaxy Watches and Galaxy Buds, plus the Galaxy SmartTags — you've got plenty of reasons to go for a Samsung and keep it in the heart of your IoT life.
Galaxy S23 Summary and final verdict
Should you buy the Galaxy S23 in 2025? If the price is right, absolutely. The camera is still impressive, the hardware remains solid, and software support is ongoing. Plus, its design still feels modern and sleek.
Samsung offers refurbished Galaxy S23 units starting around $620. Certified options on Amazon and Best Buy range from $400 to $500, with open-box variants around $620. However, the 256GB model is a bit tricky to find! If you can grab one for $600 or less, it’s a good deal — just make sure it’s in good condition or refurbished by a reputable seller. And if you're buying from the second-hand market, double-check that the unit is compatible with your carrier.
Once you navigate those details, you’ll find the Galaxy S23 remains a fast, reliable, and enjoyable smartphone experience.
