Xiaomi 12S

  • Faster 67W wired and 50W wireless charging
  • Potentially better thermal management with Snapdragon 8+ Gen 1
  • More compact and lightweight design

  • Less versatile camera system
  • Likely lower peak display brightness
  • No integrated S Pen

Samsung Galaxy S22 Ultra 5G

  • Superior display quality and brightness
  • More versatile camera system with advanced zoom
  • Integrated S Pen for productivity and creativity

  • Slower charging speeds
  • Potential for thermal throttling (especially Exynos variant)
  • Larger and heavier design

Display Comparison

The Samsung Galaxy S22 Ultra’s display is a clear standout, achieving a measured peak brightness of 1266 nits, significantly exceeding what’s likely available on the Xiaomi 12S (spec not provided, but Xiaomi typically lags Samsung in peak brightness). The S22 Ultra’s infinite contrast ratio, coupled with its adaptive refresh rate, delivers a more immersive viewing experience. While the 12S likely offers a high-quality panel, it’s unlikely to match the S22 Ultra’s color accuracy and outdoor visibility. The S22 Ultra’s larger screen size also benefits content consumption and multitasking.

Camera Comparison

The Galaxy S22 Ultra’s camera system is far more comprehensive. While both phones offer capable photography, the S22 Ultra’s strengths lie in its versatility, particularly its dual-telephoto lens setup enabling impressive zoom capabilities. The S22 Ultra’s image processing leans towards vibrant, shareable photos, while Xiaomi often aims for a more natural look. The 12S’s camera is likely excellent, but lacks the S22 Ultra’s dedicated hardware for long-range photography and video stabilization. The S22 Ultra’s video recording capabilities are also more advanced, supporting higher resolutions and frame rates.

Performance

The Xiaomi 12S’s Snapdragon 8+ Gen 1 (4nm) offers a notable advantage in thermal efficiency over the Galaxy S22 Ultra’s Exynos 2200 (4nm - Europe) or Snapdragon 8 Gen 1 (4nm - ROW). The ‘+’ designation in the Snapdragon indicates optimizations for sustained performance, reducing the likelihood of throttling during extended gaming sessions. While the S22 Ultra’s CPU clock speeds are comparable (2.8/3.0 GHz X2 vs 3.19 GHz), the 8+ Gen 1’s architecture and process node give it an edge. The 12S’s CPU configuration (1x3.19 GHz Cortex-X2, 3x2.75 GHz Cortex-A710, 4x1.80 GHz Cortex-A510) is nearly identical to the S22 Ultra, but the Snapdragon’s GPU is generally more efficient.

Battery Life

Both devices achieve an endurance rating of 108 hours, suggesting similar overall battery life despite differing battery capacities (not specified for the 12S). However, the Xiaomi 12S significantly outperforms the S22 Ultra in charging speed. 67W wired charging delivers a full charge in just 42 minutes, compared to the S22 Ultra’s 45W charge which is slower. The 50W wireless charging on the 12S is also substantially faster than the S22 Ultra’s 15W Qi wireless charging. The 12S also offers 10W reverse wireless charging, while the S22 Ultra provides only 4.5W.

Buying Guide

Buy the Xiaomi 12S if you prioritize peak performance in short bursts, demand the fastest charging speeds (67W wired, 50W wireless), and prefer a more compact flagship form factor. Buy the Samsung Galaxy S22 Ultra 5G if you value a larger, brighter display, a more versatile camera system with advanced zoom capabilities, the productivity benefits of the S Pen, and a longer software support lifecycle.

Frequently Asked Questions

❓ Does the Exynos 2200 chip in the European S22 Ultra overheat during demanding tasks like gaming?
The Exynos 2200 has been known to exhibit more thermal throttling than the Snapdragon 8 Gen 1, particularly during prolonged gaming sessions. While Samsung implemented software optimizations, the 12S’s Snapdragon 8+ Gen 1 generally maintains cooler temperatures and more consistent performance under load.
❓ Is the 50W wireless charging on the Xiaomi 12S significantly faster in real-world use?
Yes, 50W wireless charging is considerably faster than the S22 Ultra’s 15W Qi wireless charging. Expect a full wireless charge on the 12S in around 57 minutes, while the S22 Ultra will take considerably longer, making the 12S a better choice for users who frequently rely on wireless charging.
❓ How does the camera processing differ between the Xiaomi 12S and the Samsung Galaxy S22 Ultra?
Samsung typically boosts colors and contrast for more visually appealing, shareable photos. Xiaomi often aims for a more natural and realistic look. This difference is subjective, but users who prefer vibrant images will likely favor the S22 Ultra, while those seeking accuracy may prefer the 12S.
❓ Is the S Pen on the Galaxy S22 Ultra useful for everyday tasks beyond note-taking?
Absolutely. The S Pen offers a range of features, including Air Actions for remote control, handwriting-to-text conversion, and precise editing capabilities. It's particularly useful for professionals who need to annotate documents, sign PDFs, or perform detailed photo editing on the go.
