ZTE nubia Z70S Ultra
- Exceptional battery life (12:52h active use)
- Thermally efficient Snapdragon 8 Elite chipset
- High peak display brightness (1395 nits)
- 80W charging is slower than Oppo’s 100W
- Camera specs are currently unknown
Oppo Find X7
- Ultra-fast 100W charging (0-100% in 26 min)
- Powerful Dimensity 9300 chipset for peak performance
- Likely excellent display quality (based on Oppo’s history)
- Potentially shorter battery life due to less efficient chipset
- Dimensity 9300 may throttle under sustained load
Display Comparison
The nubia Z70S Ultra boasts a peak brightness of 1395 nits, ensuring excellent visibility even in direct sunlight. While the Oppo Find X7’s display specifications aren’t provided, Oppo typically employs high-quality AMOLED panels. The Snapdragon 8 Elite’s image signal processor (ISP) benefits from this brightness, providing better dynamic range in photos and videos. Without knowing the Find X7’s refresh rate or PWM dimming frequency, it’s difficult to assess potential eye strain differences, but the nubia’s high brightness is a clear advantage for outdoor use.
Camera Comparison
Without detailed camera specifications for both devices, a direct comparison is limited. However, the chipset’s ISP plays a crucial role. The Snapdragon 8 Elite’s ISP is known for its excellent image processing capabilities, particularly in low-light conditions. The Oppo Find X7’s Dimensity 9300 also features a capable ISP, but its performance will depend on the sensor and lens choices. The absence of information regarding sensor sizes and apertures makes it impossible to determine which phone will deliver superior image quality. We can assume both will offer advanced computational photography features, but the Snapdragon’s proven track record gives the nubia a slight edge.
Performance
The core difference lies in the chipsets: Qualcomm’s Snapdragon 8 Elite (3nm) versus MediaTek’s Dimensity 9300 (4nm). The Snapdragon 8 Elite utilizes a unique octa-core configuration (2x4.32 GHz Oryon V2 Phoenix L + 6x3.53 GHz Oryon V2 Phoenix M) designed for optimized performance and efficiency. The Dimensity 9300, with its Cortex-X4 cores (1x3.25 GHz & 3x2.85 GHz), focuses on raw processing power. The 3nm process of the Snapdragon 8 Elite should translate to better thermal efficiency, reducing throttling during extended gaming sessions compared to the 4nm Dimensity 9300. This means the nubia Z70S Ultra is likely to maintain higher frame rates for longer periods.
Battery Life
The nubia Z70S Ultra’s active use battery score of 12:52h is a significant advantage. While the Oppo Find X7 offers faster charging at 100W (0-100% in 26 minutes) compared to the nubia’s 80W, the nubia’s superior battery life provides more real-world usability. The Oppo’s 100W charging is convenient, reaching 50% in just 10 minutes, but a larger battery capacity and more efficient chipset, as seen in the nubia Z70S Ultra, ultimately deliver a better user experience for those who heavily use their phones.
Buying Guide
Buy the ZTE nubia Z70S Ultra if you need exceptional battery life for demanding tasks, value sustained performance over short bursts of peak power, and appreciate a more thermally managed device. Buy the Oppo Find X7 if you prioritize absolute CPU and GPU horsepower for graphically intensive games or applications, and are willing to accept potentially shorter battery life and faster heat build-up in exchange for that performance.
