Display Comparison

Both the nubia Z20 and Galaxy S10+ boast 'Infinite' contrast ratios, a common marketing term for OLED panels. However, the Z20 achieves a measured peak brightness of 615 nits, while the S10+ reaches 4.514 nits in sunlight. This suggests the S10+ offers superior visibility in bright outdoor conditions. While both utilize OLED technology, the S10+’s higher peak brightness provides a noticeable advantage for outdoor use. The lack of refresh rate information for the Z20 means we can't compare smoothness, but the S10+’s panel is known for its color accuracy.

Camera Comparison

Both devices offer photo and video capabilities, but detailed sensor information is lacking for the Z20. The S10+ is known for its versatile camera system, though details on specific sensor sizes and apertures are not provided in the context data. Without specifics on the Z20’s camera hardware, it’s difficult to make a direct comparison. The S10+’s reputation for image processing and overall camera quality gives it an edge, assuming similar shooting conditions. The absence of details on the Z20’s camera prevents a thorough analysis.

Performance

The nubia Z20 features the Qualcomm Snapdragon 855+ (7nm), utilizing an octa-core CPU configuration with a prime core clocked at 2.96 GHz. The Galaxy S10+, depending on the region, comes with either the Exynos 9820 (8nm) or the Snapdragon 855 (7nm). The Snapdragon 855+ in the Z20 offers a slight performance edge over the standard 855, and potentially over the Exynos 9820, particularly in sustained workloads due to its improved thermal characteristics. The Exynos 9820, while capable, is known to throttle more aggressively under prolonged stress. The Z20’s architecture benefits users who engage in extended gaming sessions or demanding tasks.

Battery Life

The nubia Z20 boasts an endurance rating of 100 hours, significantly exceeding the Galaxy S10+'s 91 hours. This translates to longer usage between charges. The Z20 also supports 27W wired charging with PD2.0, enabling faster charging speeds compared to the S10+'s 15W wired charging. The S10+ adds the convenience of 15W wireless charging and 4.5W reverse wireless charging, features absent on the Z20. For users prioritizing rapid replenishment, the Z20’s faster wired charging is a clear advantage, while the S10+ offers wireless charging flexibility.

Buying Guide

Buy the ZTE nubia Z20 if you need exceptional battery life, prioritize sustained gaming performance, and appreciate faster wired charging. This phone is ideal for power users and those frequently away from a charger. Buy the Samsung Galaxy S10+ if you prefer a more refined software experience, value wireless charging and reverse wireless charging capabilities, and prioritize a well-established ecosystem with broader accessory support.
