vivo X70 Pro

  • Superior battery endurance (123h rating)
  • Faster 44W wired charging
  • Excellent camera performance, especially in portrait and low-light

  • Slightly less bright display than the S21 Ultra
  • Chipset performance may be slightly lower than Snapdragon 888

Samsung Galaxy S21 Ultra 5G

  • Brighter display (1023 nits)
  • Potentially faster performance with Snapdragon 888 variant
  • Versatile camera system with multiple lenses

  • Slower 25W wired charging
  • Lower battery endurance (114h rating)
  • Exynos variant may exhibit thermal throttling

Display Comparison

Both phones feature 'Infinite' contrast ratio displays, but the Samsung Galaxy S21 Ultra edges out the vivo X70 Pro in peak brightness, reaching 1023 nits compared to the X70 Pro’s 993 nits. This difference is noticeable in direct sunlight. While both offer excellent viewing experiences, the S21 Ultra’s higher brightness and potentially higher refresh rate (depending on settings) provide a slight advantage for outdoor visibility and smoother scrolling. The S21 Ultra also benefits from a variable refresh rate (LTPO) which can dynamically adjust to save battery, a feature not explicitly mentioned for the X70 Pro.

Camera Comparison

Both phones excel in photography, but approach it differently. The Galaxy S21 Ultra’s camera system is known for its versatility, offering multiple lenses and high-resolution sensors. The X70 Pro, however, prioritizes image quality and computational photography. While specific sensor details are missing for the X70 Pro, its focus on portraiture and low-light performance is a key selling point. The S21 Ultra’s larger main sensor likely captures more light, but the X70 Pro’s image processing algorithms may produce more pleasing results in certain scenarios. Both phones offer video recording capabilities, but the X70 Pro’s gimbal stabilization system provides superior video smoothness, especially when shooting handheld.

Performance

The chipset is a key differentiator. The Galaxy S21 Ultra ships with either the Exynos 2100 (international) or the Snapdragon 888 (USA/China), both built on a 5nm process. The vivo X70 Pro utilizes the Mediatek Dimensity 1200 (international) or the Exynos 1080 (China), the Dimensity being on a 6nm node and the Exynos 1080 on a 5nm node. The Snapdragon 888 and Exynos 2100 generally offer higher peak CPU and GPU performance, particularly in sustained workloads, due to their more advanced architectures (Cortex-X1 core in the Samsung phones). However, the Dimensity 1200 is a very capable chip, and its 6nm process may offer better thermal efficiency, potentially reducing throttling during extended gaming sessions. The S21 Ultra’s LPDDR5 RAM is standard, while the X70 Pro’s RAM type isn’t specified, but is likely LPDDR4X. This could contribute to a slight performance edge for the S21 Ultra in memory-intensive tasks.

Battery Life

The Galaxy S21 Ultra has an endurance rating of 114 hours, while the vivo X70 Pro achieves 123 hours. This suggests the X70 Pro offers slightly better battery life despite having a smaller battery capacity (not specified in the data). This is likely due to the more efficient Dimensity 1200 chipset and potentially more aggressive power management. The S21 Ultra supports 25W wired charging, 15W wireless, and 4.5W reverse wireless, while the X70 Pro offers 44W wired and 5W reverse wired. The X70 Pro’s faster wired charging significantly reduces charging times, reaching a full charge much quicker than the S21 Ultra.

Buying Guide

Buy the vivo X70 Pro if you need a consistently excellent camera system, particularly for portrait and low-light photography, and prefer a more refined, less bloated software experience. Buy the Samsung Galaxy S21 Ultra 5G if you prioritize a brighter, more vibrant display for media consumption, demand the absolute fastest performance (especially with the Snapdragon variant), and value the broader ecosystem of Samsung features and accessories.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the Galaxy S21 Ultra overheat during prolonged gaming sessions?
The Exynos 2100 has been known to exhibit thermal throttling under sustained load, particularly during demanding games. While Samsung implemented software optimizations, the Snapdragon 888 variant generally performs better in this regard. The vivo X70 Pro’s Dimensity 1200, with its 6nm process, may offer better thermal efficiency, potentially leading to less throttling.
❓ Is the 2MP macro camera on the Galaxy S21 Ultra actually useful for detailed close-up shots?
Generally, 2MP macro cameras on flagship phones are more of a marketing feature than a genuinely useful tool. The low resolution often results in soft, lacking detail images. The X70 Pro doesn't explicitly mention a macro lens, suggesting a focus on quality over quantity in its camera setup.
❓ Does the Samsung Galaxy S21 Ultra support 90fps or higher frame rates in popular games like PUBG Mobile?
The Galaxy S21 Ultra can achieve high frame rates in PUBG Mobile, but it depends on the graphics settings and the specific variant (Snapdragon or Exynos). While 90fps is achievable, maintaining a stable frame rate at the highest settings may require lowering the graphics quality. The Dimensity 1200 in the X70 Pro is also capable of handling PUBG Mobile at high frame rates, but performance will vary based on optimization.
❓ What are the key differences between the international and USA/China variants of the Samsung Galaxy S21 Ultra?
The primary difference lies in the chipset. International models use the Exynos 2100, while USA and China models typically feature the Qualcomm Snapdragon 888. The Snapdragon variant generally offers better performance and thermal management, but the Exynos version is still a capable performer.
