Camera Comparison: Real-World Shots Matter 📸
When it comes to the camera, both devices are pushing the limits of mobile photography. The Samsung Galaxy S24 Ultra comes equipped with a 200MP primary sensor, delivering breathtaking clarity, dynamic range, and low-light performance. The periscope telephoto lens offers up to 100x Space Zoom, which still remains unrivaled in 2025.
On the other side, OnePlus 12 has significantly improved its camera game with a 50MP Sony LYT-808 main sensor and a Hasselblad-tuned color calibration system. Its images look incredibly natural, especially in daylight. However, it slightly lags behind in zooming power compared to the Galaxy S24 Ultra.
If you’re someone who captures videos often, the S24 Ultra’s 8K recording with enhanced stabilization gives it a strong edge. But OnePlus fans won’t be disappointed either—its 4K 60fps cinematic mode brings vibrancy and fluidity to casual videography. Real-world tests show that Samsung leads in versatility, while OnePlus excels in color science.
Performance & Speed: Snapdragon Showdown ⚡
Both phones run on the mighty Snapdragon 8 Gen 3 processor, built on a 4nm architecture, offering lightning-fast speed, lower thermal output, and more AI efficiency. In day-to-day performance, app launches, multitasking, and heavy gaming feel seamless on both phones.
However, the Galaxy S24 Ultra pairs the chip with Samsung’s One UI 6.1, which integrates Galaxy AI features for productivity, like live call translation and generative photo editing. Meanwhile, the OnePlus 12’s OxygenOS 14 offers a near-stock Android experience that feels snappy and bloat-free.
In benchmark tests, Samsung edges out OnePlus by a small margin, but in practical use, the differences are barely noticeable. It boils down to personal preference – whether you like the customizability of One UI or the speed-focused, minimalist design of OxygenOS.
Battery & Charging: Fast vs Efficient 🔋⚡
Battery life is a strong suit for both, but they approach it differently. The OnePlus 12 packs a 5,400mAh battery, slightly larger than Samsung’s 5,000mAh. It shows in real usage, with OnePlus lasting a few hours longer under heavy multitasking or video playback.
But the real game-changer is OnePlus’s 100W SUPERVOOC fast charging, which can take the phone from 1 to 100% in just about 25 minutes. In contrast, Samsung offers 45W fast charging, which feels slower in comparison.
Wireless charging is present in both, but Samsung supports reverse wireless charging which is ideal for accessories like earbuds or smartwatches. Overall, OnePlus is unbeatable in charging speed, while Samsung is more power-efficient throughout the day thanks to adaptive refresh rates and software optimization.
Display & Design: Style Meets Substance 💎
The Galaxy S24 Ultra features a 6.8-inch Dynamic AMOLED 2X display with QHD+ resolution and an ultra-smooth 120Hz refresh rate. The bezels are ultra-thin, and the Gorilla Armor glass offers added scratch and drop resistance. Its squared edges and titanium frame give it a very premium and bold look.
Meanwhile, the OnePlus 12’s 6.82-inch AMOLED ProXDR display is equally stunning, with peak brightness reaching 4500 nits—ideal for outdoor viewing. It also supports 120Hz and comes with Dolby Vision and HDR10+, making it a treat for binge-watchers and gamers.
Design-wise, OnePlus keeps it sleek with curved edges, but Samsung goes with a boxier, executive-style approach. If you’re into aesthetics and usability, this part of the comparison comes down to personal taste, as both displays are among the best in the world right now.
Software Support & Updates: Long-Term Trust ✅
Samsung wins the software race hands down by offering 7 years of OS and security updates, aligning with Google’s Pixel promise. This makes the Galaxy S24 Ultra a future-proof device that will remain relevant even in 2031.
OnePlus promises 4 years of major updates and 5 years of security patches, which is still commendable but not as extensive. If you’re someone who holds on to your phone for more than 3-4 years, Samsung’s long-term support gives peace of mind.
Final Verdict: Which One Should You Buy? 🏆
If you’re looking for the ultimate Android experience with top-tier cameras, long software support, and a feature-rich ecosystem, the Samsung Galaxy S24 Ultra is your best bet. It’s pricey, but it justifies the cost with its sheer versatility and futuristic tools.
However, if fast charging, clean UI, excellent performance, and value for money are your priorities, the OnePlus 12 is a no-brainer. It’s nearly half the price of Samsung in some markets and still delivers elite-level features.
Both phones are powerhouses in their own right, and choosing one depends on what matters most to you—be it camera innovation, software longevity, or rapid performance.
