Display Comparison

The Samsung Galaxy S24 Ultra boasts a significantly brighter display, reaching a measured 1447 nits compared to the OnePlus 12’s 1155 nits. This translates to superior visibility in direct sunlight. Both utilize LTPO technology for adaptive refresh rates, conserving battery life, but Samsung’s panel is generally regarded as having superior color accuracy and viewing angles. While both offer excellent displays, the S24 Ultra’s brightness advantage is a tangible benefit for outdoor use.

Camera Comparison

Both devices offer capable camera systems, but Samsung’s S24 Ultra provides a more versatile experience. While both focus on photo and video, the S24 Ultra’s larger main sensor and advanced image processing algorithms deliver superior dynamic range and detail in challenging lighting conditions. The S24 Ultra’s telephoto capabilities are also more robust, offering greater zoom range and image quality. The OnePlus 12’s camera is excellent, but lacks the refinement and feature set of Samsung’s flagship.

Performance

Both phones are powered by the Qualcomm SM8650-AB/AC Snapdragon 8 Gen 3 (4nm), but subtle CPU clock speed differences exist. The S24 Ultra’s CPU peaks at 3.39GHz, slightly higher than the OnePlus 12’s 3.3 GHz. In real-world usage, this difference is minimal. Both devices utilize LPDDR5x RAM, ensuring snappy multitasking. However, Samsung’s more sophisticated thermal management system, coupled with a larger vapor chamber, likely allows for sustained peak performance during extended gaming sessions, mitigating potential throttling.

Battery Life

The OnePlus 12 offers a compelling charging advantage with its 100W wired charging (26 minutes to 100% internationally, 30 minutes in the US), significantly faster than the S24 Ultra’s 45W charging (65% in 30 minutes). While the S24 Ultra’s battery life is slightly longer in active use (13:49h vs 14:11h for the OnePlus 12), the OnePlus 12’s faster charging mitigates any concerns about running out of power. The OnePlus 12 also offers 50W wireless charging, dwarfing the S24 Ultra’s 15W wireless charging.

Buying Guide

Buy the OnePlus 12 if you prioritize raw performance-per-dollar, lightning-fast 100W charging, and a clean Android experience. You'll get a flagship-level phone without the premium price tag. Buy the Samsung Galaxy S24 Ultra if you demand the best possible display, a versatile camera system with advanced features, and the seamless integration of the Samsung ecosystem, even if it means paying a premium.

Frequently Asked Questions

❓ Does the OnePlus 12’s 100W charging degrade the battery health faster than the S24 Ultra’s 45W charging?
While faster charging generates more heat, OnePlus employs battery health management algorithms to minimize degradation. The OnePlus 12’s charging system intelligently adjusts charging speed based on battery condition and usage patterns, mitigating long-term battery health concerns. However, all batteries degrade over time, regardless of charging speed.
❓ Is the Samsung Galaxy S24 Ultra’s S Pen stylus essential for everyday use, or is it a niche feature?
The S Pen is not essential for all users, but it adds significant functionality for note-taking, sketching, and precise control. Professionals who frequently annotate documents or artists who enjoy digital drawing will find the S Pen invaluable. For casual users, it’s a convenient bonus but not a necessity.
❓ How does the software experience differ between OxygenOS on the OnePlus 12 and One UI on the Samsung Galaxy S24 Ultra?
OxygenOS is known for its clean, near-stock Android experience with subtle customizations, prioritizing speed and simplicity. One UI offers a more feature-rich and visually distinct experience, with extensive customization options and Samsung-specific apps and services. Preference is subjective, but OxygenOS appeals to purists, while One UI caters to users who want more out-of-the-box features.
❓ Will the OnePlus 12 get as many software updates and security patches as the Samsung Galaxy S24 Ultra?
Samsung typically provides longer software support for its flagship devices. The S24 Ultra is promised 7 years of OS updates and security patches. OnePlus typically offers 3 major Android updates and 4 years of security patches. This is a significant difference, making the S24 Ultra a better long-term investment for software support.
