Xiaomi Redmi K80 Ultra
- Potentially faster CPU performance with Dimensity 9400+
- PD3.0 wired charging compatibility
- Likely more affordable price point
- Potentially shorter battery life
- Camera system may not be as advanced as the X100 Pro
vivo X100 Pro
- Exceptional battery life (13:53h active use)
- Brighter display (1472 nits)
- 50W wireless and reverse wired charging
- Dimensity 9300 may be slightly slower than the 9400+
- Potentially higher price
Display Comparison
The vivo X100 Pro boasts a significantly brighter display, reaching a measured peak of 1472 nits, ensuring excellent visibility even in direct sunlight. While the K80 Ultra’s display specs are currently unknown, vivo’s panel offers a superior viewing experience in bright conditions. The X100 Pro likely utilizes LTPO technology for adaptive refresh rates, contributing to battery efficiency, a feature we anticipate the K80 Ultra may lack. Bezels and color accuracy will require hands-on testing, but the X100 Pro’s brightness advantage is a clear win.
Camera Comparison
The vivo X100 Pro is positioned as a camera-centric device, and while specific sensor details are missing for both phones, vivo’s history suggests a focus on image quality and computational photography. The X100 Pro’s camera system is designed for both photo and video, likely featuring advanced OIS and large apertures for low-light performance. The K80 Ultra, while capable, is likely to prioritize overall performance over camera specialization. We can expect the X100 Pro to excel in dynamic range and detail, while the K80 Ultra may offer a more neutral image processing style.
Performance
The Xiaomi Redmi K80 Ultra’s Mediatek Dimensity 9400+ (3nm) chipset, with its Cortex-X925 prime core clocked at 3.63 GHz, is designed for peak performance, theoretically surpassing the vivo X100 Pro’s Dimensity 9300 (4nm). The 9400+’s architecture, featuring more Cortex-X4 cores (3 vs 3 in the 9300), suggests a stronger focus on multi-core performance. However, the 4nm process of the 9300 may offer better thermal efficiency, potentially mitigating throttling under sustained load. The K80 Ultra’s LPDDR5x RAM configuration is standard, but the 9300’s optimized architecture could deliver comparable real-world performance despite the clock speed difference.
Battery Life
The vivo X100 Pro’s 13:53h active use score demonstrates impressive battery endurance, a significant advantage over what we might expect from a performance-focused device like the K80 Ultra. Both phones support 100W wired charging, with the X100 Pro reaching 50% charge in 14 minutes. However, the X100 Pro adds the convenience of 50W wireless charging and reverse wired charging, offering greater flexibility. The K80 Ultra’s PD3.0 support is a welcome addition for compatibility with a wider range of chargers, but the X100 Pro’s overall battery package is more compelling.
Buying Guide
Buy the Xiaomi Redmi K80 Ultra if you need uncompromising CPU performance for demanding tasks like video editing, emulation, or competitive mobile gaming. Its Dimensity 9400+ offers a clear advantage in raw processing power. Buy the vivo X100 Pro if you prefer a more balanced experience with exceptional camera quality, long-lasting battery life (13:53h active use), and the convenience of 50W wireless charging.
