Display Comparison

The Samsung Galaxy S23 Ultra boasts a significantly brighter display, reaching a measured 1274 nits, compared to an unspecified peak brightness for the ROG Phone 6. While both likely utilize AMOLED technology, the S23 Ultra’s infinite contrast ratio suggests superior black levels. The ROG Phone 6’s display is geared towards high refresh rates for gaming, but the S23 Ultra’s adaptive refresh rate (LTPO) likely offers better power efficiency. Bezels are likely comparable, but the S23 Ultra’s curved edges may appeal to some users.

Camera Comparison

The S23 Ultra’s camera system is a clear standout. While both phones offer photo and video capabilities, the S23 Ultra’s likely features a larger main sensor and more advanced image processing algorithms. The ROG Phone 6’s camera is likely adequate, but it’s not a primary selling point. The S23 Ultra’s superior optics and software will deliver significantly better image quality, especially in low-light conditions. The ROG Phone 6’s camera is likely tuned for faster capture speeds, but the S23 Ultra’s overall versatility and image quality are unmatched.

Performance

The Galaxy S23 Ultra’s Snapdragon 8 Gen 2 (4nm) represents a generational leap over the ROG Phone 6’s Snapdragon 8+ Gen 1 (4nm). The Gen 2 features a newer Cortex-X3 prime core clocked at 3.36 GHz versus the ROG Phone 6’s 3.19 GHz Cortex-X2, alongside more efficient Cortex-A715 cores. This translates to improved CPU and GPU performance, and crucially, better thermal efficiency, reducing throttling during extended gaming sessions. While the ROG Phone 6 benefits from active cooling solutions, the S23 Ultra’s more efficient chip minimizes the need for aggressive throttling in the first place. Both utilize LPDDR5x RAM, but the S23 Ultra’s optimized software and chipset integration likely provide a smoother overall experience.

Battery Life

The Samsung Galaxy S23 Ultra demonstrates superior battery endurance, achieving an active use score of 13:24h and an endurance rating of 126h. While the ROG Phone 6’s battery capacity is unspecified, the S23 Ultra’s larger battery and more efficient chipset provide a substantial advantage. The ROG Phone 6 compensates with faster 65W wired charging (100% in 42 minutes) compared to the S23 Ultra’s 45W charging (65% in 30 minutes). However, the S23 Ultra offers 15W wireless charging and 4.5W reverse wireless charging, features absent on the ROG Phone 6.

Buying Guide

Buy the Asus ROG Phone 6 if you are a serious mobile gamer who prioritizes sustained performance, customizable controls, and rapid charging. You’ll benefit from its dedicated gaming features and cooling system. Buy the Samsung Galaxy S23 Ultra if you value a premium camera experience, all-day battery life, a stunning display, and a more polished, versatile software experience. It’s the better choice for content creators and everyday users.

Frequently Asked Questions

❓ Does the ROG Phone 6’s cooling system truly prevent throttling during extended gaming sessions?
While the ROG Phone 6’s active cooling system is effective, the Snapdragon 8+ Gen 1 still generates more heat than the Snapdragon 8 Gen 2 in the S23 Ultra. The S23 Ultra’s more efficient chipset minimizes throttling, potentially offering more consistent performance over very long gaming periods even without active cooling.
❓ How does the S23 Ultra’s 45W charging compare to the ROG Phone 6’s 65W in real-world usage?
Although the ROG Phone 6 charges faster on paper, the S23 Ultra’s larger battery and optimized charging curve mean the difference in actual charging time isn’t as significant as the wattage gap suggests. The ROG Phone 6 reaches 100% in 42 minutes, while the S23 Ultra reaches 65% in 30 minutes.
❓ Is the S23 Ultra’s camera system overkill for casual users?
While the S23 Ultra’s camera is incredibly powerful, its advanced features and image quality are beneficial even for casual users. The improved low-light performance and ease of use make it a superior choice for everyday photography compared to the ROG Phone 6.
❓ Can the ROG Phone 6 handle demanding games like Genshin Impact at maximum settings?
Yes, the ROG Phone 6 can handle Genshin Impact at maximum settings, but you may experience some frame drops during intense scenes due to thermal throttling. The S23 Ultra will likely maintain more consistent frame rates due to its more efficient chipset.
