Display Comparison

The Xiaomi 13 Ultra boasts a significantly brighter display, reaching a measured 1207 nits, compared to an unspecified peak brightness for the ROG Phone 6. While the ROG Phone 6 likely features a high refresh rate, the Ultra’s brightness advantage is crucial for outdoor visibility. Both devices likely employ AMOLED panels, but the Ultra’s superior brightness and potentially wider color gamut make it the better choice for media consumption and content creation. The ROG Phone 6’s display is geared towards fast response times for gaming, but the Ultra’s overall quality is higher.

Camera Comparison

The Xiaomi 13 Ultra is unequivocally the camera champion. While specific sensor details are missing for both, Xiaomi’s focus on camera technology is well-established. The Ultra’s camera system is designed for both photo and video, likely featuring a large main sensor and advanced image processing algorithms. The ROG Phone 6, while capable, prioritizes other features and will likely offer a less sophisticated camera experience. The absence of details on the ROG Phone 6’s camera suggests it’s not a primary selling point, and any 2MP macro or depth sensors are likely to be of limited utility.

Performance

The Xiaomi 13 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 3.2 GHz, alongside improved Cortex-A715 and A710 performance cores, resulting in faster CPU and GPU performance. While the ROG Phone 6’s cooling system is robust, the more efficient 4nm process of the Gen 2 in the Ultra, combined with potentially more advanced thermal management, should lead to less throttling during sustained workloads. The Ultra’s LPDDR5x RAM further contributes to faster data access and overall system responsiveness.

Battery Life

The Xiaomi 13 Ultra demonstrates superior charging capabilities with 90W wired charging (35 minutes to 100%) and 50W wireless charging (49 minutes to 100%), compared to the ROG Phone 6’s 65W wired (42 minutes) and 10W reverse wired. The Ultra’s active use battery score of 10:09h and endurance rating of 108h indicate excellent battery life, likely due to the efficiency of the Snapdragon 8 Gen 2. While the ROG Phone 6’s battery capacity is unspecified, the Ultra’s faster charging and longer endurance provide a significant advantage for users who demand all-day battery life.

Buying Guide

Buy the Asus ROG Phone 6 if you need a device specifically engineered for extended gaming sessions, prioritize cooling and customizable performance profiles, and value gaming-centric accessories. Buy the Xiaomi 13 Ultra if you prefer a top-tier camera system, a brighter and more color-accurate display, and a more polished, everyday smartphone experience with faster charging and wireless capabilities.

Frequently Asked Questions

❓ Does the Snapdragon 8+ Gen 1 in the ROG Phone 6 throttle significantly during prolonged gaming sessions?
While the ROG Phone 6 features a robust cooling system, the Snapdragon 8+ Gen 1 is known to generate heat under sustained load. Throttling is possible, potentially reducing frame rates over extended gaming periods. The Xiaomi 13 Ultra’s newer Snapdragon 8 Gen 2 and potentially more efficient thermal design should mitigate this issue.
❓ How does the 50W wireless charging on the Xiaomi 13 Ultra compare to the convenience of the ROG Phone 6’s reverse wireless charging?
The Xiaomi 13 Ultra’s 50W wireless charging is significantly faster than the ROG Phone 6’s 10W reverse wireless charging. The Ultra can fully charge wirelessly in 49 minutes, while the ROG Phone 6’s reverse wireless charging is primarily intended for accessories and offers a much slower charging speed.
❓ Is the Xiaomi 13 Ultra a viable option for competitive mobile gaming, or is it primarily focused on photography?
Despite its camera focus, the Xiaomi 13 Ultra’s Snapdragon 8 Gen 2 chipset delivers exceptional performance capable of handling demanding mobile games. However, it lacks the dedicated gaming features like triggers and advanced cooling found on the ROG Phone 6, making it less ideal for hardcore competitive gamers.
