vivo Y51s
- Potentially better power efficiency with the Exynos 880's 8nm process.
- May run cooler under sustained load.
- Competitive GPU performance for gaming.
- Significantly slower 18W charging.
- CPU clock speeds are slightly lower than the nova 7i.
- Likely lacks the software optimizations of Huawei's camera.
Huawei nova 7i
- 40W fast charging – 70% in 30 minutes.
- Slightly higher CPU clock speeds for improved multitasking.
- Kirin 810's 7nm process offers good efficiency.
- May run slightly warmer under heavy load.
- Huawei's software ecosystem may be a concern for some users.
- Potentially more aggressive image processing.
Display Comparison
Neither device boasts a standout display. Both likely utilize LCD panels, common in this price bracket. The focus here isn't on cutting-edge tech like LTPO or high refresh rates. The real difference, absent from the provided specs, likely lies in color calibration and peak brightness. Huawei historically leans towards more saturated colors, while vivo often aims for a more natural look. Bezels are expected to be similar, contributing minimally to the overall user experience.
Camera Comparison
Without detailed sensor information, a direct camera comparison is difficult. However, the market positioning suggests both phones will feature multi-camera setups with a primary sensor, ultrawide, and depth/macro lenses. The absence of Optical Image Stabilization (OIS) on either device is a notable omission. Image processing will be a key differentiator; Huawei’s image algorithms are known for their aggressive sharpening and vibrant colors, while vivo often aims for a more balanced and natural look. The 2MP macro cameras found on many phones in this segment are largely marketing features and offer limited practical benefit.
Performance
The core of the difference lies in the chipsets. The Huawei nova 7i’s Kirin 810, fabricated on a 7nm process, has a slight advantage in raw CPU power with its 2x2.27 GHz Cortex-A76 cores compared to the vivo Y51s’ 2x2.0 GHz Cortex-A77 cores on the 8nm Exynos 880. While both utilize Cortex-A55 efficiency cores at similar clock speeds (1.8 GHz vs 1.88 GHz), the 7nm process of the Kirin 810 generally translates to better power efficiency and potentially slightly improved sustained performance. The Exynos 880, however, benefits from Mali-G76 MP5 GPU, which may offer competitive gaming performance. The impact of RAM speed (LPDDR4X is likely on both) is minimal in real-world usage.
Battery Life
The Huawei nova 7i’s 40W wired charging is a significant advantage. The ability to reach 70% charge in just 30 minutes drastically reduces downtime compared to the vivo Y51s’ 18W charging. While battery capacity isn’t specified, the faster charging speed of the nova 7i effectively mitigates any potential disadvantage from a slightly smaller battery. The Exynos 880’s 8nm process may offer better power efficiency, potentially leading to longer standby times, but the convenience of rapid charging is a compelling benefit for many users.
Buying Guide
Buy the vivo Y51s if you prioritize long-term battery life and a potentially cooler operating temperature during sustained tasks, even if it means slower charging. Buy the Huawei nova 7i if you value rapid charging, enabling you to quickly top up your battery and minimize interruptions, and if you frequently switch between multiple applications.
