Meizu 18 Pro

  • Significantly faster wired and wireless charging
  • More compact and pocketable design
  • Potentially better thermal management due to smaller size

  • Less versatile camera system
  • Lower display brightness
  • Limited availability compared to Samsung

Samsung Galaxy S21 Ultra 5G

  • Brighter and more vibrant display
  • More versatile camera system with superior zoom
  • Wider availability and ecosystem support

  • Slower charging speeds
  • Larger and less comfortable to hold for some users
  • Exynos variant may exhibit thermal throttling

Display Comparison

The Samsung Galaxy S21 Ultra boasts a significantly brighter display, peaking at 1023 nits measured, compared to the Meizu 18 Pro’s unspecified peak brightness. This translates to better outdoor visibility. While both likely utilize high refresh rate panels, Samsung’s display benefits from its larger size and potentially more advanced LTPO technology for adaptive refresh rate control, improving battery efficiency. The S21 Ultra’s ‘Infinite’ contrast ratio suggests a superior OLED panel with deeper blacks, enhancing the viewing experience for media consumption.

Camera Comparison

The Samsung Galaxy S21 Ultra’s camera system is far more comprehensive. While both phones offer excellent photo and video capabilities, the S21 Ultra’s multiple lenses (including a dedicated telephoto lens with significant optical zoom) provide greater versatility. The Meizu 18 Pro’s camera specs are less detailed, lacking information on sensor sizes and lens apertures. The S21 Ultra’s larger main sensor and advanced image processing algorithms will likely result in superior low-light performance and dynamic range. Ignoring the often-underperforming 2MP macro lenses found on many phones, the S21 Ultra’s overall camera package is a clear advantage.

Performance

Both phones utilize the Qualcomm Snapdragon 888 5G (5nm) in the USA/China markets, meaning CPU performance will be very similar. The S21 Ultra’s international variant with the Exynos 2100, while also 5nm, historically exhibits slightly lower sustained performance and potentially higher thermal throttling compared to the Snapdragon variant. The S21 Ultra’s CPU clocks slightly higher (2.9 GHz vs 2.84 GHz on the Meizu’s X1 core), but this difference is unlikely to be noticeable in everyday use. Both devices feature ample RAM (12GB in comparable configurations) and LPDDR5 support, ensuring smooth multitasking. Thermal management will be a key differentiator, with the Meizu’s smaller form factor potentially offering better heat dissipation.

Battery Life

Both devices have an endurance rating of 114h, suggesting similar overall battery life despite differing battery capacities (not specified for the Meizu). However, the Meizu 18 Pro significantly outperforms the S21 Ultra in charging speed. 40W wired charging allows for a 40% charge in 15 minutes and a full charge in 50 minutes, compared to the S21 Ultra’s slower 25W wired charging. The Meizu also offers 40W wireless charging, dwarfing the S21 Ultra’s 15W Qi wireless charging. The Meizu’s 10W reverse wireless charging is also more useful than the S21 Ultra’s 4.5W offering.

Buying Guide

Buy the Meizu 18 Pro if you need a genuinely compact flagship experience, value extremely fast 40W wireless charging, and prefer a cleaner, less feature-bloated Android skin. Buy the Samsung Galaxy S21 Ultra 5G if you prioritize a stunning, bright display, a highly versatile camera system with excellent zoom capabilities, and a broader ecosystem of accessories and support.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the international S21 Ultra overheat during prolonged gaming sessions?
The Exynos 2100 variant of the S21 Ultra has been known to exhibit more thermal throttling than the Snapdragon 888 version during extended, demanding tasks like gaming. While not a complete deal-breaker, users planning on heavy gaming should be aware of this potential limitation and consider the Snapdragon variant if available in their region.
❓ Is the 40W wireless charging on the Meizu 18 Pro truly faster in real-world use?
Yes, the Meizu 18 Pro’s 40W wireless charging is significantly faster than the S21 Ultra’s 15W Qi wireless charging. This translates to a much quicker top-up when using wireless charging pads, making it a compelling feature for users who frequently utilize this charging method.
❓ How does the camera processing differ between the Meizu 18 Pro and the Samsung Galaxy S21 Ultra?
Samsung’s camera processing tends to produce more vibrant and saturated images, often with boosted colors and contrast. Meizu typically aims for a more natural and realistic look, prioritizing accuracy over visual pop. This difference in processing style caters to different user preferences.
❓ Is the Meizu 18 Pro’s software experience significantly different from Samsung’s One UI?
Yes. Meizu’s Flyme OS is known for its cleaner, more minimalist interface compared to Samsung’s feature-rich One UI. Flyme OS generally offers a smoother and less cluttered experience, appealing to users who prefer a stock Android-like feel with subtle customizations.
