The smartphone industry moves fast. A device that feels revolutionary today can seem outdated just a few years later. When the Samsung Galaxy S23 Ultra launched in 2023, it was widely considered one of the most powerful Android smartphones ever made. Fast forward to 2026, and the big question remains: does the S23 Ultra still hold its own, or has it been left behind by newer flagships?
Let’s take a closer look at how Samsung’s former powerhouse performs in 2026.
A Quick Look Back at the S23 Ultra
At launch, the S23 Ultra represented the pinnacle of Samsung’s smartphone engineering. It featured a massive 6.8-inch AMOLED display with a 1440 × 3088 resolution and a dynamic 120Hz refresh rate, delivering extremely sharp visuals and smooth scrolling.
Under the hood, it was powered by the Qualcomm Snapdragon 8 Gen 2 for Galaxy, paired with 8GB or 12GB of RAM and storage options up to 1TB.
Samsung also packed in:
A 200MP primary camera
3× and 10× optical zoom telephoto lenses
A 12MP ultra-wide camera
A 5,000mAh battery
Integrated S Pen support
These features helped cement the S23 Ultra as a top-tier Android flagship.
But three years later, how well do these specs hold up?
Performance in 2026: Still Very Capable
One of the most impressive things about the S23 Ultra is how well it has aged in terms of performance.
The Snapdragon 8 Gen 2 chip remains powerful enough for demanding tasks like gaming, video editing, and heavy multitasking. In real-world tests, the phone can still maintain over 50 FPS in demanding games like Genshin Impact before thermal throttling occurs.
For everyday usage; social media, streaming, messaging, and browsing, the S23 Ultra still feels fast and responsive.
Compared to newer devices released in 2025 and 2026, however, it lacks the latest AI-focused processors and efficiency improvements.
Still, for most users, performance is far from a problem.
Camera System: Still One of the Best Zoom Phones
The S23 Ultra’s camera system remains one of its strongest selling points.
Its 200MP primary sensor uses pixel-binning technology to combine multiple pixels into one, producing highly detailed images with excellent color accuracy in most lighting conditions.
But the real standout feature is the zoom.
The phone includes:
3× optical zoom
10× optical periscope zoom
Up to 100× digital zoom
Even in 2026, the 10× optical zoom remains better than many newer smartphones, especially for long-distance photography.
Video performance also holds up well with 4K recording at 60fps and 8K video support.
However, newer flagships now outperform it in:
Low-light photography
AI image processing
Computational photography
There have also been reports that some software updates temporarily affected camera performance on certain devices.
Display: Still Gorgeous
Samsung has always excelled at displays, and the S23 Ultra is no exception.
The 6.8-inch AMOLED panel remains incredibly sharp and vibrant, with peak brightness reaching around 1750 nits, making it easy to use outdoors.
The LTPO adaptive refresh rate (1–120Hz) also helps save battery during light tasks like reading or browsing.
Even in 2026, the screen is still competitive with many newer devices.
Battery Life: Good, But Not Cutting Edge
Battery performance is still respectable thanks to the 5,000mAh battery, which can often last a full day of heavy use.
Charging, however, shows the phone’s age.
45W wired charging
15W wireless charging
While this was fast in 2023, many modern flagships now support 60W–120W charging, meaning they can fully charge in less than half the time.
Still, for users who charge overnight, this is rarely a major issue.
Software Support and Longevity
Samsung committed to four years of Android updates and five years of security updates for the S23 series.
That means:
Android updates will likely end around 2027
Security updates will follow suit in 2028
So while the phone still receives updates in 2026, its long-term software lifespan is approaching its final phase.
The S Pen Advantage
One feature that still makes the S23 Ultra unique is the built-in S Pen.
The stylus supports:
Remote camera control
Air gestures
Note-taking and drawing
Interestingly, some newer Samsung models removed certain Bluetooth S Pen functions, making the S23 Ultra especially appealing for users who rely on those capabilities.
Should You Buy the S23 Ultra in 2026?
The answer depends on the price.
Buy it if:
You can find it at a significant discount or refurbished
You want one of the best zoom cameras on a smartphone
You need the S Pen
You want a premium phone without paying flagship prices
Skip it if:
You want the latest AI features
You want very fast charging
You plan to keep your phone for more than 4–5 years
Our Verdict
The Samsung Galaxy S23 Ultra remains an impressive device even three years after launch. Its powerful processor, exceptional zoom camera, stunning display, and built-in S Pen ensure that it still feels like a flagship in 2026.
However, the smartphone world has moved on. Newer devices offer better AI capabilities, improved low-light photography, and much faster charging.
Still, if you can get the S23 Ultra at the right price, it remains one of the smartest “value flagship” purchases in 2026.
