Xiaomi 15S Pro
- Potentially groundbreaking Xring O1 chipset
- Faster wired and wireless charging speeds
- Reverse wireless charging capability
- Unproven chipset performance and software optimization
- Missing display brightness data
- Limited camera information
Asus ROG Phone 8 Pro
- Proven Snapdragon 8 Gen 3 performance
- Exceptional battery life (14:43h active use)
- Bright and color-accurate display (1765 nits)
- Slower wired charging than Xiaomi (especially in India)
- Wireless charging speed is lower
- Camera details are vague
Display Comparison
The Asus ROG Phone 8 Pro boasts a significantly brighter display, reaching a measured 1765 nits, making it far more usable outdoors than the Xiaomi 15S Pro (brightness data unavailable). While the Xiaomi likely employs a high-quality panel, the ROG Phone’s brightness advantage is substantial. Both devices likely support high refresh rates, but the ROG Phone’s brightness and color accuracy will be superior for media consumption and gaming. The ROG Phone’s display is also likely to have a higher PWM dimming rate, potentially reducing eye strain for sensitive users.
Camera Comparison
Detailed camera specifications for the Xiaomi 15S Pro are unavailable. The Asus ROG Phone 8 Pro’s camera capabilities are described as 'Photo / Video', lacking specifics. Without sensor size, aperture, or OIS details for either device, a meaningful comparison is difficult. However, Asus ROG Phones typically prioritize video recording capabilities, while Xiaomi flagships often excel in still photography. The absence of detailed camera information suggests neither phone is a primary focus for camera enthusiasts.
Performance
The core of this comparison lies in the chipsets. The Xiaomi 15S Pro’s Xring O1, built on a 3nm process, theoretically offers greater efficiency and transistor density compared to the Asus ROG Phone 8 Pro’s Snapdragon 8 Gen 3 (4nm). However, the Snapdragon 8 Gen 3 is a mature platform with optimized drivers and software support. The Xring O1’s 10-core configuration (2x3.9GHz Cortex-X925, 4x3.4GHz Cortex-A725, 2x1.9GHz Cortex-A725, 2x1.8GHz Cortex-A520) is complex, and its real-world performance advantage over the Snapdragon 8 Gen 3’s octa-core setup (1x3.3 GHz Cortex-X4, 3x3.2 GHz Cortex-A720, 2x3.0 GHz Cortex-A720, 2x2.3 GHz Cortex-A520) remains to be seen. The ROG Phone benefits from Qualcomm’s Adreno GPU, a proven performer in mobile gaming. Both devices likely utilize LPDDR5x RAM, but thermal management will be crucial; the Snapdragon 8 Gen 3’s 4nm node offers a potential advantage in sustained performance.
Battery Life
The Asus ROG Phone 8 Pro demonstrates a clear advantage in battery life, achieving 14 hours and 43 minutes of active use. The Xiaomi 15S Pro’s battery capacity is unknown, but its 90W wired charging, 50W wireless, and 10W reverse wireless charging capabilities are impressive. The ROG Phone offers 65W wired (International) / 30W (India), 15W wireless (Qi), and 10W reverse wired. While the Xiaomi charges faster, the ROG Phone’s superior battery life mitigates the charging speed difference. The ROG Phone’s 39-minute 0-100% charge time (International) is competitive, but the Indian variant’s 30W charging is significantly slower.
Buying Guide
Buy the Xiaomi 15S Pro if you are an early adopter fascinated by cutting-edge silicon and willing to potentially troubleshoot early software quirks for a possible performance edge. Buy the Asus ROG Phone 8 Pro if you prioritize a polished, reliable gaming experience, exceptional battery life, and a brighter, more visible display, even in direct sunlight.
