Two years after buying the Samsung Galaxy S23 Ultra, I still carry it daily for testing, photography, gaming, and content work. That alone says a lot in a smartphone market where brands push yearly upgrades aggressively. While testing newer Android phones with my small gadget review crew in 2025, one thing became obvious: the S23 Ultra still holds up better than many expected.
That raises the big question many buyers still ask today: is s23 ultra worth buying in 2025?
After months of side-by-side testing against newer flagship phones, battery tracking, camera comparisons, and real-world daily use, the answer is yes for most people. In fact, the S23 Ultra now sits in a sweet spot between flagship performance and better pricing.
Instead of sounding like a spec sheet, this review focuses on practical experience. So if you are upgrading from an older Samsung phone, switching from iPhone, or looking for a premium Android device without spending over $1,300, here is what you should know.

Why the Galaxy S23 Ultra Still Feels Premium
Several phones lose their “flagship feel” after two years. However, the Galaxy S23 Ultra still feels modern immediately after picking it up.
The display remains one of the brightest panels we tested in direct sunlight this year. Outdoors, brightness peaks high enough to comfortably watch YouTube videos under harsh afternoon light. Meanwhile, scrolling feels incredibly fluid thanks to the adaptive 120Hz refresh rate.
Samsung also nailed thermals with this model. During gaming tests using PUBG Mobile, Call of Duty Mobile, and Genshin Impact, the phone stayed cooler than some newer devices powered by hotter chipsets.
Key Facts:
- Peak brightness reaches around 1,750 nits
- Battery still averages 6–7 hours screen-on time
- Games run smoothly at high graphics settings
- UFS 4.0 storage keeps app loading fast
- S Pen latency remains extremely responsive
If you enjoy productivity, the built-in S Pen still separates this phone from most Android competitors. I regularly use it for quick notes, screenshot edits, and signing PDF documents during testing sessions.

Real-World Performance After 2 Years
Benchmark scores look nice on paper. Yet long-term performance matters more in daily use.
After two years, the Snapdragon 8 Gen 2 for Galaxy still performs exceptionally well. Apps open instantly, multitasking stays smooth, and video rendering speeds remain fast enough for short-form creators.
During our testing, exporting a 4K one-minute video clip to TikTok took under 48 seconds. That result still competes with newer flagship Android devices.
More importantly, the phone rarely stutters. Even with over 200 installed apps, background memory management stayed reliable.
| Task | Performance Result |
|---|---|
| 4K Video Editing | Smooth |
| Gaming | Stable FPS |
| Multitasking | Excellent |
| Thermal Management | Cooler than expected |
| App Launch Speed | Fast |
Additionally, Samsung DeX continues to impress. Connecting the phone to a monitor instantly creates a desktop-style experience useful for productivity work.

Camera Performance in 2025
The camera system remains the strongest reason many buyers still choose the S23 Ultra today.
Samsung’s 200MP sensor captures detailed photos consistently. Daylight shots show strong dynamic range, while low-light images maintain good sharpness without excessive noise.
During our photography tests across Lagos city streets, indoor cafés, and outdoor evening scenes, the zoom system still outperformed many newer phones priced under $900.
The 10x optical zoom especially remains impressive. Unlike digital-heavy zoom systems on cheaper phones, images stay surprisingly usable even beyond 20x.
What Still Impresses:
- Excellent daylight photography
- Reliable low-light performance
- Sharp portrait edge detection
- Useful 10x optical zoom
- Strong video stabilization
That said, the camera is not perfect.
Fast-moving subjects occasionally introduce shutter lag, particularly indoors. Samsung improved this issue with updates, but it still appears sometimes compared to Pixel phones.

Battery Life and Charging Experience
Battery health often determines whether an older flagship still feels usable.
Fortunately, the Galaxy S23 Ultra still performs well here.
After two years of usage involving gaming, hotspot sharing, social media testing, and video streaming, battery health remained around 89% during our checks.
Average screen-on time stayed between 6 and 7 hours daily.
That translates into:
- Full workday usage comfortably
- Long YouTube streaming sessions
- Reliable navigation during travel
- Enough reserve for evening gaming
Charging speeds still feel decent, although newer Chinese phones now charge significantly faster.
Using Samsung’s official 45W charger, charging from 10% to 100% took roughly 58 minutes during testing.
Samsung’s official support page also confirms continued software support for the device through future Android updates.

S23 Ultra vs S24 Ultra and S25 Ultra
Newer phones naturally introduce upgrades. Still, many buyers overestimate how large those improvements actually feel in real use.
| Feature | S23 Ultra | S24 Ultra | S25 Ultra |
|---|---|---|---|
| Performance | Excellent | Slightly Better | Better AI Features |
| Battery | Very Good | Very Good | Improved Efficiency |
| Camera | Excellent | Minor Improvements | Better Processing |
| Value | Best Value | Expensive | Very Expensive |
After testing all three devices, the S23 Ultra still delivers the best price-to-performance balance for most users.

More importantly, it now costs significantly less than newer models while keeping most flagship-level features intact.
