The battle between the OnePlus 12 and the Samsung Galaxy S24 base model is one of the most compelling in today’s smartphone market. Both devices sit just below the ultra-premium tier—offering flagship-level performance at a more accessible price—but they approach the experience from different philosophies. OnePlus leans into raw speed, aggressive pricing, and enthusiast-focused features, while Samsung delivers polished software, superior camera consistency, and long-term ecosystem integration. For consumers deciding between them, the choice isn’t about specs alone—it’s about priorities.
This isn’t a contest between budget phones. The OnePlus 12 and Galaxy S24 are both powerful, well-built devices that deliver top-tier experiences. But only one can better serve the needs of users who want flagship power without paying $1,000+. Let’s break down where each excels—and where compromises must be made.
Performance: Raw Power vs Optimized Efficiency
At the heart of any modern smartphone is its chipset, and here both devices go head-to-head with the latest silicon available. The OnePlus 12 is powered by the Qualcomm Snapdragon 8 Gen 3, paired with up to 16GB of LPDDR5X RAM. The Samsung Galaxy S24 also uses the same processor globally (a shift from previous years when Exynos variants were offered), ensuring consistent performance regardless of region.
In real-world use, both phones feel snappy. Apps launch instantly, multitasking is seamless, and even graphically demanding games like *Genshin Impact* or *Call of Duty Mobile* run at maximum settings without stuttering. However, differences emerge under sustained load.
OnePlus has historically prioritized peak performance, and the 12 continues this tradition. Its vapor chamber cooling system allows it to maintain higher clock speeds for longer during extended gaming or video rendering sessions. Benchmarks reflect this: in sustained AnTuTu tests, the OnePlus 12 often scores 5–8% higher than the S24 due to better thermal management.
Samsung, on the other hand, tunes its hardware for balance. The S24 runs slightly cooler and quieter, trading off marginal peak performance for improved battery efficiency and reduced fan noise (yes, some flagships get loud). This makes it better suited for users who value silence and longevity over milliseconds saved in app transitions.
“While both use the same SoC, OnePlus pushes thermal limits further—ideal for gamers. Samsung optimizes for everyday smoothness and long-term reliability.” — David Lin, Mobile Hardware Analyst at TechPulse
Display Quality and Design Language
The display is where subjective preference plays a major role. The OnePlus 12 features a 6.82-inch QHD+ (3168 x 1440) LTPO AMOLED panel with a 120Hz refresh rate. It hits up to 4500 nits peak brightness, making it exceptionally visible under direct sunlight. OnePlus also uses curved edges—a divisive design choice that enhances immersion but can lead to accidental touches.
The Galaxy S24 opts for a smaller 6.2-inch FHD+ (2340 x 1080) Dynamic AMOLED 2X display, also with a 120Hz refresh rate and LTPO support. While lower in resolution, Samsung’s pixel density and color calibration are industry-leading. The flat screen improves usability and reduces glare, appealing to those who prefer practicality over flair.
Design-wise, the S24 feels more compact and pocketable. At 167g, it's significantly lighter than the OnePlus 12’s 220g. The aluminum frame and Gorilla Glass Victus 2 on both models ensure durability, but Samsung’s Armor Aluminum frame adds an extra layer of drop resistance.
OnePlus counters with IP65 dust and water resistance—adequate for splashes but not submersion—while the S24 offers full IP68 certification, surviving depths of up to 1.5 meters for 30 minutes. For outdoor enthusiasts or frequent travelers, this difference matters.

Camera Systems: Consistency vs Flexibility
Photography separates good phones from great ones. The Samsung Galaxy S24 takes a methodical approach: a triple rear setup with a 50MP main sensor (f/1.8, OIS), a 12MP ultrawide (f/2.2), and a 10MP telephoto (3x optical zoom, f/2.4). Samsung’s processing engine applies intelligent HDR, noise reduction, and color science that produces reliable results across lighting conditions.
The OnePlus 12, co-engineered with Hasselblad, features a similar configuration: 50MP main (Sony LYT-808, f/1.6, OIS), 48MP ultrawide (f/2.0), and a 64MP periscope telephoto with 3x optical and up to 120x digital zoom. The larger ultrawide sensor captures more detail in low light, and the periscope lens outperforms Samsung’s in super-zoom scenarios.
In daylight, both produce excellent photos. Samsung favors natural skin tones and balanced contrast; OnePlus leans into dynamic range and sharpness, sometimes oversharpening textures. In low light, the OnePlus 12’s wider aperture gives it a slight edge in capturing brighter scenes, though Samsung’s multi-frame processing reduces noise more effectively.
Video is another point of divergence. The S24 supports 8K recording at 30fps and advanced stabilization via AI-enhanced Super Steady mode. The OnePlus 12 maxes out at 4K/60fps but includes professional-grade tools like LOG profile recording and DOL-HDR for filmmakers.
Real-World Example: Travel Photography Test
A travel blogger tested both phones on a weekend trip through Iceland. Shooting glaciers, waterfalls, and cityscapes in rapidly changing weather, she found the S24 required less post-processing—colors were accurate straight out of camera, and Auto HDR handled high-contrast skies flawlessly. However, when photographing distant mountain ridges, the OnePlus 12’s superior zoom let her capture details the S24 couldn’t match without cropping. She ultimately preferred the S24 for daily blogging but kept the OnePlus 12 as a secondary device for landscape specialization.
Battery Life and Charging Speed
Battery endurance is critical for mid-tier flagships, where users expect all-day performance without constant charging anxiety.
The OnePlus 12 packs a 5400mAh battery—the largest in any recent flagship—with 80W wired charging and 50W wireless. In real-world testing, it consistently lasts 8–9 hours of screen-on time. A 10-minute charge restores nearly 50% capacity, making it ideal for users with erratic schedules.
The Galaxy S24 houses a smaller 2555mAh unit, reflecting its compact size. It manages around 6–7 hours of screen time, sufficient for moderate users but tight for heavy multitaskers. Its 25W wired and 15W wireless charging are significantly slower. While adaptive fast charging protects battery health over time, the trade-off is convenience.
Software optimization helps the S24 stretch its battery further. Samsung’s One UI 6.1 includes granular app sleep controls and AI-based resource allocation. Still, no software trick compensates for half the physical capacity.
