Display Comparison

The Samsung Galaxy S9+ boasts a clear advantage in display technology. While both feature 10nm processors, the S9+'s 'Infinite' contrast ratio, reaching 4.537 in sunlight, significantly outperforms the U12+'s 1818:1 nominal and 3.085 sunlight contrast. This translates to deeper blacks and more vibrant colors, especially outdoors. Both likely utilize Super AMOLED panels, but Samsung’s calibration and peak brightness are demonstrably superior. The U12+’s display isn’t *bad*, but it doesn’t compete with the S9+’s visual punch.

Camera Comparison

Both devices offer capable photo and video recording, but a detailed analysis requires sample comparisons beyond the provided specs. Both feature dual-camera setups, but sensor sizes and lens apertures are crucial details missing from the context. The S9+'s variable aperture lens (f/1.5 and f/2.4) is a significant advantage, allowing for better low-light performance and depth-of-field control. The U12+ likely relies more heavily on software processing to compensate. The presence of OIS (Optical Image Stabilization) on both is expected, but its effectiveness varies. Ignoring the likely low-resolution 2MP secondary sensors, the primary camera's capabilities are the deciding factor.

Performance

Performance is a more nuanced comparison. The U12+ and the USA/LATAM/China variant of the S9+ both utilize the Qualcomm Snapdragon 845. However, the EMEA S9+ features Samsung’s Exynos 9810. While the Exynos 9810 is a capable chip, the Snapdragon 845 generally exhibits better sustained performance and thermal management. Both CPUs feature octa-core designs, but the S9+'s Mongoose M3 cores (in the Exynos variant) are architecturally different from the Kryo 385 Gold cores in the Snapdragon. The real-world difference is often subtle, but the Snapdragon-equipped models are less prone to throttling under prolonged heavy load. Both phones likely use LPDDR4 RAM, impacting multitasking capabilities.

Battery Life

Battery life is where the Galaxy S9+ truly shines. Its endurance rating of 86 hours dwarfs the U12+'s 64 hours. This translates to a full day of heavy use for the S9+, while the U12+ may require a midday top-up. While the U12+ supports 18W Quick Charge 3.0, achieving 50% charge in 35 minutes, the S9+'s 15W Quick Charge 2.0 is slower. However, the S9+ also supports Qi wireless charging, a convenience the U12+ lacks. The larger battery capacity in the S9+ is the primary driver of its superior endurance.

Buying Guide

Buy the HTC U12+ if you prioritize a unique, pressure-sensitive frame and are comfortable with potentially shorter battery life. Its Snapdragon 845 (in some regions) delivers excellent performance. Buy the Samsung Galaxy S9+ if you value all-day battery life, a stunning display with exceptional outdoor visibility, and a more polished software experience with wider accessory availability.

Frequently Asked Questions

❓ Does the Exynos 9810 in the Galaxy S9+ overheat during demanding tasks like gaming?
While the Exynos 9810 is a powerful chip, it is known to generate more heat than the Snapdragon 845 under sustained load. This can lead to thermal throttling, reducing performance during extended gaming sessions or video recording. The Snapdragon variant of the S9+ generally exhibits better thermal management.
❓ Is the 2MP depth sensor on either phone actually useful for improving portrait mode photos?
The 2MP depth sensors on both phones provide limited benefit. While they assist in creating a bokeh effect, the quality is often inferior to the portrait mode achieved through software processing alone. They are primarily a marketing feature rather than a significant improvement to image quality.
❓ Can the Samsung Galaxy S9+ reliably maintain 60fps in graphically intensive games like PUBG?
The Galaxy S9+ (especially the Snapdragon variant) can generally maintain 60fps in PUBG, but performance may dip during intense firefights or with high graphics settings enabled. Optimizing the game settings is crucial for a smooth gaming experience. The U12+ with the Snapdragon 845 offers comparable performance.
❓ How does the pressure-sensitive frame on the HTC U12+ enhance the user experience?
The U12+'s Edge Sense allows users to trigger actions by squeezing the sides of the phone. This can be customized to launch apps, take photos, or perform other functions. While innovative, its usefulness is subjective and depends on individual preferences. Some users may find it gimmicky or prone to accidental activation.
