Display Comparison

Both devices are expected to feature high-quality displays, but the vivo X100 Ultra boasts a measured peak brightness of 1801 nits, significantly exceeding what’s typically found in flagship phones. This translates to superior readability under direct sunlight. While the Meizu 21’s display specifications aren’t detailed, it’s likely to offer excellent color accuracy, but may fall short of the X100 Ultra’s peak brightness. The absence of LTPO information for the Meizu 21 means it may not dynamically adjust refresh rates as efficiently as the X100 Ultra, potentially impacting battery life.

Camera Comparison

Detailed camera specifications for the Meizu 21 are currently unavailable. The vivo X100 Ultra is expected to feature a cutting-edge camera system, likely including a large main sensor (potentially 1-inch or larger) with optical image stabilization (OIS). The X100 Ultra’s image processing algorithms are known for their vibrant and detailed results. Without specific details on the Meizu 21’s camera hardware, it’s difficult to assess its capabilities, but it will need a strong sensor and image processing pipeline to compete with the X100 Ultra.

Performance

Both the Meizu 21 and vivo X100 Ultra utilize the Qualcomm SM8650-AB Snapdragon 8 Gen 3 (4nm), featuring an identical CPU configuration: 1x3.3 GHz Cortex-X4, 3x3.2 GHz Cortex-A720, 2x3.0 GHz Cortex-A720, and 2x2.3 GHz Cortex-A520. This ensures comparable raw processing power. However, sustained performance will hinge on thermal management. The X100 Ultra’s larger chassis potentially allows for a more robust cooling system, mitigating thermal throttling during extended gaming sessions. RAM specifications are currently unknown for both devices, but LPDDR5x is expected, further enhancing performance.

Battery Life

The vivo X100 Ultra demonstrates a clear advantage in battery performance, achieving 12 hours and 55 minutes of active use. Both devices support 80W wired charging with PD3 PPS and QC4+ compatibility, but the X100 Ultra adds UFCS support for potentially faster charging with compatible adapters. Crucially, the X100 Ultra also includes 30W wireless charging and both reverse wired and wireless charging capabilities, offering unparalleled versatility. The Meizu 21 lacks wireless charging, limiting its convenience for users accustomed to this feature.

Buying Guide

Buy the Meizu 21 if you prioritize a potentially more compact form factor (based on brand history) and a streamlined software experience. Buy the vivo X100 Ultra if you demand maximum battery endurance, the convenience of wireless and reverse wireless charging, and a display that excels in outdoor visibility. The X100 Ultra caters to power users and those who rely heavily on their smartphone throughout the day.

Frequently Asked Questions

❓ Does the vivo X100 Ultra's 30W wireless charging work with all Qi-compatible chargers?
While the X100 Ultra supports the Qi wireless charging standard, achieving the full 30W speed requires a charger that specifically supports the Power Delivery (PD) protocol and the appropriate wattage. Older or non-PD-compliant Qi chargers may deliver slower charging speeds.
❓ How does the Meizu 21's software compare to the more feature-rich software found on vivo devices?
Meizu is known for its relatively clean and minimalist Flyme OS, prioritizing a streamlined user experience. Vivo’s Funtouch OS, while improved in recent iterations, typically includes more pre-installed apps and features. Users who prefer a less cluttered interface may gravitate towards the Meizu 21.
❓ Will the Snapdragon 8 Gen 3 in either phone struggle with demanding games like Genshin Impact at maximum settings?
The Snapdragon 8 Gen 3 is a powerhouse and should handle Genshin Impact at maximum settings with ease. However, sustained performance will depend on the phone's thermal management. The vivo X100 Ultra’s potentially larger chassis may offer better cooling, reducing the likelihood of throttling during extended gaming sessions.
