Display Comparison

Both the U12+ and U11+ feature similar display characteristics, but the U12+ boasts a noticeably higher contrast ratio of 1818:1 (nominal) compared to the U11+'s 1626:1. This translates to deeper blacks and more vibrant colors. Furthermore, the U12+ achieves a peak brightness of 3.085 nits in sunlight, exceeding the U11+'s 2.556 nits, improving outdoor visibility. While both displays are excellent, the U12+ offers a marginal improvement in visual quality, particularly in challenging lighting conditions.

Camera Comparison

Both devices offer capable photo and video recording, but detailed camera specs are limited in the provided data. The absence of sensor size or aperture information makes a direct comparison difficult. However, the U12+ likely benefits from the improved image signal processor (ISP) within the Snapdragon 845, potentially leading to better low-light performance and faster image processing. Without further data, it's reasonable to assume the U12+ offers a slight edge in image quality, but the real-world difference may be minimal for casual users.

Performance

The U12+’s Snapdragon 845 represents a significant architectural leap over the U11+’s Snapdragon 835. The 845, built on a 10nm process, features Kryo 385 cores clocked up to 2.8 GHz, offering a performance boost over the 835’s 2.45 GHz Kryo cores. This translates to faster app loading times, smoother multitasking, and improved gaming performance. While both chipsets are capable, the 845’s improved efficiency also contributes to better sustained performance under heavy load, reducing the likelihood of thermal throttling. The U12+ will benefit users who frequently engage in resource-intensive tasks like video editing or high-end gaming.

Battery Life

The U11+ holds a clear advantage in battery endurance, achieving a rating of 73 hours compared to the U12+'s 64 hours. Despite both phones supporting 18W wired charging with Quick Charge 3.0, the U11+'s larger battery capacity and more efficient chipset result in longer usage times. The U12+ advertises a 50% charge in 35 minutes, but this doesn't compensate for the overall lower endurance. Users prioritizing battery life will find the U11+ a more reliable companion.

Buying Guide

Buy the HTC U12+ if you demand the fastest possible performance for demanding applications and games, and are willing to accept a reduction in battery endurance. Buy the HTC U11+ if you prioritize all-day battery life, a proven track record of reliability, and value for money, especially given its current price point. The U11+ is ideal for users who prioritize longevity over bleeding-edge specs.

Frequently Asked Questions

❓ Does the Snapdragon 845 in the U12+ offer a noticeable gaming improvement over the U11+’s Snapdragon 835?
Yes, the Snapdragon 845 provides a tangible improvement in gaming performance. The newer Adreno 630 GPU in the U12+ delivers higher frame rates and smoother gameplay in demanding titles. While the U11+ can handle most games, the U12+ offers a more future-proof gaming experience, especially for graphically intensive games.
❓ Given the battery life difference, is the U12+ suitable for heavy users who rely on their phone throughout the day?
The U12+ may require more frequent charging for heavy users. Its 64-hour endurance rating is good, but falls short of the U11+'s 73 hours. Users who frequently stream video, play games, or use GPS will likely find themselves reaching for a charger before the end of the day with the U12+.
❓ Are there any known thermal throttling issues with the U12+ under sustained load?
While the Snapdragon 845 is more efficient than the 835, it can still experience thermal throttling under prolonged, intensive tasks like extended gaming sessions or 4K video recording. The U12+'s thermal management system is adequate, but users should expect some performance reduction after extended use.
