Display Comparison

Both the HTC U12+ and Samsung Galaxy S9+ feature excellent displays, but differ in contrast. The S9+ boasts an 'Infinite' contrast ratio, measured at 4.537 in sunlight, significantly exceeding the U12+'s 1818:1 nominal and 3.085 sunlight contrast. While both utilize vibrant color reproduction, the S9+'s higher contrast contributes to a more visually striking image, especially in bright outdoor conditions. Neither specification details refresh rate or panel technology (LTPO), suggesting standard 60Hz OLED panels were used.

Camera Comparison

Both devices offer capable camera systems, but detailed sensor information is lacking in the provided data. Both are described as having Photo/Video capabilities. The absence of specific sensor size or aperture details makes a direct comparison difficult. However, given Samsung’s historical strength in image processing, the S9+ likely delivers more consistently pleasing images in a wider range of conditions. The inclusion of a 2MP macro camera on either device is largely a marketing gimmick, offering minimal practical benefit due to its low resolution.

Performance

The performance landscape is nuanced. While both phones were available with the Snapdragon 845 (10nm), the Galaxy S9+ also shipped with the Exynos 9810 (10nm) in EMEA regions. The U12+ consistently features the Snapdragon 845, offering a more uniform experience. The Snapdragon 845 in both devices utilizes an octa-core configuration (4x2.8 GHz Kryo 385 Gold & 4x1.7 GHz Kryo 385 Silver). The Exynos 9810, however, employs a different architecture (4x2.7 GHz Mongoose M3 & 4x1.8 GHz Cortex-A55), which historically has shown slightly lower sustained performance and potentially higher thermal throttling compared to the Snapdragon variant. This means users with the Snapdragon S9+ will likely experience more consistent frame rates during extended gaming sessions.

Battery Life

Battery life is a clear win for the Samsung Galaxy S9+. With an endurance rating of 86 hours, it significantly outlasts the HTC U12+'s 64 hours. While the U12+ offers faster 18W wired charging with QC3 (advertised 50% in 35 minutes), the S9+'s 15W charging with QC2, coupled with its larger battery capacity, results in a more practical and reliable experience. The S9+ also supports wireless charging (Qi), a feature not explicitly mentioned for the U12+.

Buying Guide

Buy the HTC U12+ if you prioritize a unique, pressure-sensitive frame and are comfortable with potentially shorter battery life. Its 18W charging offers a quicker top-up, but the overall endurance is lower. Buy the Samsung Galaxy S9+ if you value all-day battery life, a consistently high-performing Snapdragon 845 (in US/LATAM/China models), and a more established software ecosystem. The S9+ is the safer bet for long-term usability.

Frequently Asked Questions

❓ Does the Exynos 9810 chip in the Galaxy S9+ overheat during demanding tasks like gaming?
The Exynos 9810 has historically been known to run hotter than the Snapdragon 845, potentially leading to thermal throttling during prolonged gaming sessions or intensive app usage. While Samsung implemented cooling solutions, the Snapdragon variant generally offers more consistent performance under sustained load.
❓ Is the 18W charging on the HTC U12+ significantly faster in real-world use compared to the S9+'s 15W charging?
While the U12+ advertises 50% charge in 35 minutes, the actual difference in charging speed is often marginal. The S9+'s larger battery capacity, combined with efficient power management, means the overall time to full charge may not be drastically different, and the U12+'s faster charging doesn't compensate for its lower endurance.
❓ How does the pressure-sensitive frame on the HTC U12+ enhance the user experience?
The U12+'s pressure-sensitive frame allows for customizable actions based on how firmly you grip the phone. This can be mapped to launch apps, take photos, or perform other functions, offering a unique interaction method. However, its usefulness is subjective and may not appeal to all users.
❓ Is the Galaxy S9+ still a viable option in [current year] considering its age?
Yes, the Galaxy S9+ remains a viable option for users on a budget. While it lacks the latest features like 5G and advanced camera technology, it still offers a smooth Android experience, a capable camera, and excellent battery life, particularly with the Snapdragon 845 variant.
