Display Comparison

The Samsung Galaxy S24 Ultra boasts a peak brightness of 1447 nits, ensuring excellent visibility even in direct sunlight. While the OnePlus Open 2’s display specs aren’t provided, foldable displays typically prioritize color accuracy and flexibility over peak brightness. Both likely utilize LTPO technology for adaptive refresh rates, conserving battery life. The Open 2’s foldable nature offers a larger screen real estate when unfolded, enhancing multitasking and media consumption, but introduces a crease that some users may find distracting. The S24 Ultra’s flat display minimizes reflections and offers better durability.

Camera Comparison

Detailed camera specs for the OnePlus Open 2 are missing, but given its positioning, it’s expected to feature a high-resolution main sensor. The Samsung Galaxy S24 Ultra’s camera system is well-documented, offering versatile shooting options. The S24 Ultra’s image processing prioritizes natural colors and detail, while OnePlus typically leans towards more vibrant, saturated images. The S24 Ultra’s superior optical zoom capabilities, likely exceeding the Open 2, will be a key advantage for long-distance photography. Without specific sensor details for the Open 2, it’s difficult to definitively assess its camera performance, but the S24 Ultra’s established track record gives it a lead.

Performance

The core difference lies in the chipsets. The OnePlus Open 2 features the Qualcomm SM8750-AB Snapdragon 8 Elite with Oryon V2 Phoenix cores, promising a significant performance leap over the Snapdragon 8 Gen 3 (SM8650-AC) in the S24 Ultra. The 8 Elite’s 3nm process node should deliver improved thermal efficiency, potentially reducing throttling during sustained workloads. The Open 2’s CPU configuration (2x4.32 GHz Oryon V2 Phoenix L + 6x3.53 GHz Oryon V2 Phoenix M) is architecturally distinct from the S24 Ultra’s (1x3.39GHz Cortex-X4 & 3x3.1GHz Cortex-A720 & 2x2.9GHz Cortex-A720 & 2x2.2GHz Cortex-A520), with the Oryon cores designed for higher single-core performance. While the S24 Ultra benefits from Qualcomm’s optimizations, the Open 2’s architecture suggests a potential edge in demanding tasks.

Battery Life

The Samsung Galaxy S24 Ultra achieves an impressive 13:49h of active use, demonstrating excellent battery life. The OnePlus Open 2’s battery capacity is unknown, but foldable phones often have slightly smaller batteries due to space constraints. However, the Open 2 compensates with significantly faster charging: 80W wired versus the S24 Ultra’s 45W. The Open 2 can likely achieve a substantial charge in under 30 minutes, while the S24 Ultra takes approximately 30 minutes to reach 65%. The Open 2 also offers 50W wireless charging, dwarfing the S24 Ultra’s 15W Qi wireless charging. The trade-off is endurance versus speed; the S24 Ultra lasts longer, while the Open 2 charges much faster.

Buying Guide

Buy the OnePlus Open 2 if you demand the absolute fastest Android performance, value the versatility of a foldable display, and prioritize rapid charging. You’ll benefit from the Oryon CPU’s efficiency and the unique multitasking capabilities. Buy the Samsung Galaxy S24 Ultra if you prioritize all-day battery life, a mature and feature-rich software experience, and a robust camera system with extensive zoom capabilities. It’s the safer, more polished choice for mainstream users.

Frequently Asked Questions

❓ Does the Snapdragon 8 Elite in the OnePlus Open 2 generate significantly more heat than the Snapdragon 8 Gen 3 in the S24 Ultra during prolonged gaming sessions?
The Snapdragon 8 Elite’s 3nm process node is designed for improved thermal efficiency. While both chips will generate heat under load, the 8 Elite *should* exhibit less throttling, maintaining higher sustained performance. However, the Open 2’s foldable design may present unique thermal challenges, requiring further testing to confirm real-world results.
❓ How does the 80W charging on the OnePlus Open 2 compare to the 45W charging on the S24 Ultra in terms of actual charging time from 0% to 100%?
The OnePlus Open 2’s 80W charging is substantially faster. While the S24 Ultra reaches 65% in 30 minutes, the Open 2 is expected to fully charge in under an hour. This difference is significant for users who frequently need to quickly top up their battery.
❓ Is the crease on the OnePlus Open 2’s foldable display noticeable during everyday use, and does it affect the viewing experience?
The crease is inherent to foldable display technology. While visibility varies depending on viewing angle and content, it is generally noticeable. Most users adapt to it over time, but it remains a potential drawback for those sensitive to screen imperfections. Samsung has made strides in minimizing the crease in its own foldable devices, but it's still present.
