Sony Xperia 1 II

  • Dedicated shutter button for enhanced photography experience
  • More compact and manageable form factor
  • Emphasis on manual camera controls and pro-level features

  • Significantly shorter battery life compared to the S21 Ultra
  • Less bright display, impacting outdoor visibility
  • Older chipset with less efficient power consumption

Samsung Galaxy S21 Ultra 5G

  • Exceptional battery life for all-day usage
  • Brighter and more vibrant display for superior viewing
  • Faster charging speeds and reverse wireless charging capability

  • Larger and heavier form factor
  • Software can be perceived as bloated by some users
  • Less emphasis on manual camera controls compared to the Xperia 1 II

Display Comparison

The Samsung Galaxy S21 Ultra boasts a significantly brighter display at 1023 nits compared to the Xperia 1 II’s 611 nits. This translates to superior visibility in direct sunlight. Both displays share an 'Infinite' contrast ratio, suggesting excellent black levels, but the S21 Ultra’s higher peak brightness provides a more dynamic visual experience. While both are excellent, the S21 Ultra’s panel is more easily viewable outdoors. The S21 Ultra also benefits from a dynamic refresh rate (LTPO) which the Xperia 1 II lacks, potentially improving battery efficiency.

Camera Comparison

Both devices excel in camera capabilities, but approach it differently. While both offer photo and video functionality, the Xperia 1 II emphasizes manual control and a dedicated shutter button for a more DSLR-like experience. The S21 Ultra, however, offers a more versatile system with multiple lenses and advanced computational photography. The S21 Ultra’s larger main sensor (spec not provided, but generally larger than Xperia 1 II) captures more light, resulting in better low-light performance. The S21 Ultra’s 100x Space Zoom is a notable feature absent on the Xperia 1 II. The Xperia 1 II’s strength lies in its video recording capabilities and real-time tracking autofocus.

Performance

Both phones utilize octa-core processors, but differ in architecture and fabrication. The S21 Ultra, depending on region, features either the Exynos 2100 (5nm) or the Qualcomm Snapdragon 888 5G (5nm), both built on a smaller 5nm process compared to the Xperia 1 II’s Snapdragon 865 (7nm+). This process advantage gives the S21 Ultra a theoretical edge in power efficiency and thermal management. The S21 Ultra’s Cortex-X1 core (2.9 GHz or 2.84 GHz depending on region) offers higher peak performance than the Xperia 1 II’s Cortex-A77 core (2.84 GHz). The S21 Ultra’s LPDDR5 RAM also provides faster memory speeds, contributing to smoother multitasking.

Battery Life

The Samsung Galaxy S21 Ultra delivers a substantial battery life advantage with an endurance rating of 114 hours, compared to the Xperia 1 II’s 83 hours. This difference is partially attributable to the S21 Ultra’s larger battery capacity (spec not provided, but generally larger) and the more efficient 5nm chipset. The S21 Ultra also supports faster wired charging at 25W (PD3.0) versus the Xperia 1 II’s 21W (PD), and offers reverse wireless charging, a feature missing on the Xperia 1 II. While both support wireless charging, the S21 Ultra’s 15W rate is faster than the Xperia 1 II’s 11W.

Buying Guide

Buy the Sony Xperia 1 II if you prioritize manual camera controls, a dedicated shutter button, and a more compact form factor for a flagship. You'll benefit from its focus on photography and videography features. Buy the Samsung Galaxy S21 Ultra 5G if you value all-day battery life, a brighter and more vibrant display, faster charging, and a more feature-rich software experience. It's the better choice for users who want a top-tier phone for everything.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the international S21 Ultra suffer from overheating issues?
Early reports indicated potential thermal throttling with the Exynos 2100, particularly during sustained heavy loads. However, software updates from Samsung have largely mitigated these concerns, and real-world performance is now comparable to the Snapdragon 888 variant. The 5nm process node still offers better thermal efficiency than the 7nm+ Snapdragon 865 in the Xperia 1 II.
❓ Is the 2MP macro camera on the S21 Ultra actually useful, or is it just a marketing gimmick?
While 2MP macro cameras often lack detail, the S21 Ultra’s implementation is reasonably good for casual close-up shots. However, dedicated macro photography enthusiasts will likely find it limiting compared to a dedicated macro lens. The Xperia 1 II does not include a dedicated macro camera, relying on its main sensor for close-up photography.
❓ Can the Xperia 1 II handle demanding games like PUBG Mobile at 90fps?
The Xperia 1 II can run PUBG Mobile at high frame rates, but achieving a consistent 90fps may require lowering graphics settings. The Snapdragon 865 is capable, but the S21 Ultra’s newer chipset and faster RAM provide a smoother gaming experience overall, especially with more graphically intensive titles.
❓ How does the Xperia 1 II's video recording compare to the S21 Ultra, specifically regarding stabilization?
The Xperia 1 II excels in video recording, offering a wider range of manual controls and excellent real-time tracking autofocus. While the S21 Ultra also records high-quality video, the Xperia 1 II’s stabilization is often praised for its natural look, whereas the S21 Ultra can sometimes exhibit a more digitally processed stabilization effect.
