Samsung Galaxy S25 vs Galaxy S23: two generations apart

The next big Samsung flagship launch is still months away, but there’s a steady stream of leaks and rumors fueling our imaginations. Many people are waiting for the new The Galaxy S25 series wants to upgrade, and according to the latest polls and surveys, people tend to change their phones every two years. With that in mind a comparison is made with the two year old Galaxy S23 makes a lot of sense. Today we’re going to do just that: compare the upcoming ones Galaxy S25 flagship with his grandfather, the Galaxy S23.

Keep in mind that because the S25 series is still not official, much of the information here is based on leaks and rumors. This is our preliminary version Galaxy S25 vs Galaxy S23 comparison.

The design expectations for the Galaxy S25 series don’t exactly blow us away. From what we hear, Samsung is not making any major changes and mainly sticks to minor adjustments. So expect the same flat front and back, rounded corners and flat sides that we’ve seen in recent generations. Galaxy S23 has a slightly curved design in comparison, but the camera system looks almost exactly the same. This phone started the trend with separate holes for each camera in the vanilla version, carried over from the Galaxy Ultra’s design.

When it comes to materials, we look at the usual glass and aluminum construction. No fancy stuff here for the regular and Plus models, just the Rumor has it that the Galaxy S25 Ultra will get a special titanium treatment. The older Galaxy S23 has the same smartphone construction concept: glass and metal.

Now for some more exciting news: color options. We’ve heard some interesting rumors. Normally the regular and Plus models share the same colors, but this time there may be one additional color for the Plus model. View the expected colors for the Galaxy S25 and the available colors for the Galaxy S23 below!

Galaxy S25 expected colors:

• Moon Night Blue
• Silver shade
• Sparkling blue
• Sparkling green

Galaxy S23 available colors:

• Vegetable
• Phantom Black
• Cream
• Lavender

Inside the box, you will most likely only find the phones and a USB-C cable, as this is the latest trend in planet conservation.

We expect the display of the Galaxy S25 remain largely unchanged from the previous generation, which means we’re talking about the same 6.2-inch 1-120Hz LTPO panel as the previous generation.

There are rumors that we could get the awesome anti-reflective coating we saw on the car Galaxy S24 Ultra, but nothing has been confirmed at the moment. In terms of resolution, we don’t expect a bump for the vanilla model, so it will most likely be the same 1080p panel with a pixel density of 416 PPI.

Now, the Galaxy S23 is a well-known entity and has an increasingly smaller 6.1-inch display. The brightness we measured in our display test was almost 1100 nits, which is quite impressive, as are the color accuracy and minimum brightness.

The big talking point in the Android community is the recently announced Snapdragon 8 Elite chipset. According to early benchmarks, this silicon is on par with the latest Apple A18 Pro chip, which is exciting to say the least.

The Galaxy S25 will feature the aforementioned Snapdragon 8 Elite, tuned “for Galaxy”, so we might be able to get even better performance from Samsung’s next flagship.

The Galaxy S23on the other hand, features the Snapdragon 8 Gen 2 hardware platform, and while it’s not slow, the raw performance is much lower than what the Elite model will pack.

The The Galaxy AI situation is another important point here. There’s a good chance that the Galaxy S25 gets more of the AI ​​magic thanks to the faster and better optimized AI chipset. If you’re excited about AI and find it useful, the S25 is probably better suited for long-term updates.

Speaking of updates, the seven-year software support will be present on the S25 and the Galaxy S23which is already two years old, will no longer receive Android updates by the end of 2026. On the downside, the S25 will most likely continue to get Android versions until 2032 (which seems like a sci-fi future).

Camera details are usually kept under wraps before a smartphone is launched, and the smartphone is no different Galaxy S25 series. However, some information has leaked. Rumor has it that there may be an upgrade to Sony LYTIA sensors for the main cameras on the Galaxy S25.

These new Sony sensors come with some pretty cool tech, like dual transistor pixel stacking, which could improve light capture and keep noise levels down. As for the ultra-wide-angle and telephoto cameras, it looks like they’ll stick with the same lineup as last year – for now, anyway.

In terms of flexibility, both the Galaxy S23 and the Galaxy S25 rely on the same camera concept, with one main camera, one ultra-wide-angle camera and a telephoto. Considering how important post-processing algorithms are in smartphone photography these days, we wouldn’t expect a huge difference in photo quality between the two, despite the two-year gap.

Below you will find the specifications of the camera systems on both Galaxy S25 And Galaxy S23.

Galaxy S25 series expected camera specifications:

• Main (Wide Angle) – 50 MP, f/1.8 aperture, 24mm, 1/1.56″, 1.0µm, dual pixel PDAF, OIS
• Ultrawide: 12 MP, f/2.2, 13mm, 120˚, 1/2.55″ 1.4 µm, super stable video
• 3x telephoto: 10 MP, f/2.4, 67 mm, 1/3.94″, 1.0 µm, PDAF, OIS

Galaxy S23 camera setup:

• Main (Wide) – 50 MP, f/1.8, 24mm (Wide), 1/1.56″, 1.0µm, Dual Pixel PDAF, OIS
• Ultrawide: 12 MP, f/2.2, 13mm, 120˚, 1/2.55″ 1.4 µm, super stable video
• 3x telephoto: 10 MP, f/2.4, 70mm, 1/3.94″, 1.0 µm, PDAF, OIS

But of course we have to make some comparison examples and put them side by side in order to make an objective judgment.

The latest leaks are not very optimistic about the battery of the Galaxy S25. It looks like we’ll probably get the same 4,000mAh cell as before, which isn’t an improvement over the previous model. However, according to industry insiders, Samsung plans to use AI to help optimize and extend the battery life of the S25 series. We can’t say how well this AI optimization will work until we can run our own battery tests, but there’s more disappointing news: fast charging.

And leaked certification documents show that Samsung is playing it safe again when it comes to charging speeds. According to 3C certification (a Chinese regulatory body), the Galaxy S25 stays at the same 25W wired charging speed as the Galaxy S23so don’t expect any improvements there. We’re still in the dark about wireless charging speeds, but chances are they won’t change either.

The Galaxy S23 had a 3900 mAh battery (only 100 mAh smaller) and had no AI features to increase efficiency. In our tests it only managed about 5 hours and 49 minutes, which ranked 61st among phones tested in recent years, which isn’t exactly impressive.

This one looks pretty simple, at least on paper. There’s a good reason to upgrade if you’re out of… Galaxy S23. The new flagship, the Galaxy S25will not only feature one of the fastest chipsets on the market, but will also come with seven years of upgrades and plenty of AI tricks.

Now the camera system doesn’t look like a huge upgrade, and the same goes for the battery and charging, as well as the screen. So if you’re looking for a spare phone or you find a good deal, the Galaxy S23 is still a great phone. We’ll update this comparison with benchmarks and a final verdict once we’re done reviewing the Galaxy S25.
