- High 144Hz refresh rate display
- Longer battery endurance
- Higher price point
- Gaming-focused features may be unnecessary for casual users
Display Comparison
Both phones utilize 7nm+ Snapdragon 865 platforms, but the ROG Phone 3’s display boasts a measured peak brightness of 719 nits, suggesting a more visible experience in direct sunlight compared to the K30 Pro (brightness data unavailable). While both offer an 'infinite' contrast ratio, the ROG Phone 3’s 144Hz refresh rate, a feature absent in the K30 Pro, provides a significantly smoother visual experience, particularly in fast-paced games. The ROG Phone 3’s larger display size also caters to more immersive gaming.
Camera Comparison
Both devices offer 'Photo / Video' capabilities, but detailed camera specifications are lacking. Without sensor size or aperture data, a direct comparison is difficult. However, given Asus’s focus on gaming, the ROG Phone 3’s camera is likely tuned for quick snapshots and social media sharing, while the K30 Pro might prioritize more balanced image processing. The absence of detail suggests neither phone is a standout camera performer in this segment.
Performance
The Asus ROG Phone 3 edges out the Redmi K30 Pro with its Snapdragon 865 5G+ chipset, featuring a slightly higher peak CPU clock speed of 3.10 GHz versus the K30 Pro’s 2.84 GHz. This translates to a marginal performance advantage in CPU-intensive tasks. Both devices share the same CPU core configuration (1x Cortex-A77 @ 2.84/3.10 GHz, 3x Cortex-A77 @ 2.42 GHz, 4x Cortex-A55 @ 1.80 GHz). However, the ROG Phone 3’s advanced cooling system is crucial for sustaining peak performance during extended gaming sessions, mitigating thermal throttling that the K30 Pro might experience.
Battery Life
Both the Redmi K30 Pro and Asus ROG Phone 3 share a 30W wired charging capability, supporting PD3.0 and QC4 standards, achieving a 100% charge in approximately 63 minutes. The ROG Phone 3 boasts an endurance rating of 120 hours, suggesting optimized power management. While the K30 Pro’s battery capacity is unknown, the ROG Phone 3’s longer endurance rating indicates a more efficient overall power consumption profile, likely due to software optimizations and a larger battery (implied by the endurance rating).
Buying Guide
Buy the Xiaomi Redmi K30 Pro if you need a powerful daily driver with excellent performance for the price, a capable camera, and don't require specialized gaming features. Buy the Asus ROG Phone 3 if you are a hardcore mobile gamer who prioritizes sustained performance under heavy load, demands the highest possible refresh rates, and appreciates features like AirTriggers and a robust cooling system.
