HMD Skyline

  • Exceptional battery life (10:47h active use)
  • Wireless charging (Qi2 and magnetic)
  • More affordable price point

  • Significantly slower performance than the 12R
  • Slower charging speed (33W)

OnePlus 12R

  • Flagship-level performance with Snapdragon 8 Gen 2
  • Incredibly fast 100W charging (26 minutes to full)
  • Brighter display for better outdoor visibility

  • Shorter battery life (14:32h active use)
  • No wireless charging support

Display Comparison

Both devices feature 4nm chipsets, but their displays differ noticeably. The OnePlus 12R boasts a higher peak brightness of 1181 nits compared to the HMD Skyline’s 1060 nits, resulting in better visibility in direct sunlight. While both likely utilize AMOLED panels (though not explicitly stated), the 12R’s higher brightness and potentially wider color gamut offer a more vibrant viewing experience. The absence of LTPO technology in either device suggests a standard 120Hz refresh rate, potentially impacting power consumption compared to adaptive refresh rate displays.

Camera Comparison

Without detailed camera specifications, a direct comparison is limited. However, the chipset difference suggests the 12R will have a more powerful image signal processor (ISP), enabling faster image processing and potentially better low-light performance. The Snapdragon 8 Gen 2’s ISP supports more advanced features like 8K video recording and improved HDR capabilities. While the Skyline will likely produce acceptable images, the 12R is expected to offer a more refined and versatile camera experience. We assume both phones will feature a multi-camera setup, but the quality of the sensors and lenses will be key differentiators.

Performance

The performance gap is significant. The OnePlus 12R’s Snapdragon 8 Gen 2 (SM8550-AB) is a substantial upgrade over the HMD Skyline’s Snapdragon 7s Gen 2 (SM7435-AB). The 8 Gen 2 features a prime Cortex-X3 core clocked at 3.2 GHz, alongside higher-clocked Cortex-A715 and A710 cores, providing a considerable boost in CPU and GPU performance. The Skyline’s A78 cores, while capable, are a generation behind and clocked lower. This translates to faster app loading times, smoother multitasking, and a superior gaming experience on the 12R. The 12R also benefits from potentially faster LPDDR5x RAM, further enhancing performance.

Battery Life

The OnePlus 12R’s 100W wired charging is a game-changer, achieving a full charge in just 26 minutes. This is dramatically faster than the HMD Skyline’s 33W charging. However, the Skyline compensates with superior battery life, achieving 10:47h of active use compared to the 12R’s 14:32h. This suggests the Skyline’s more efficient chipset and potentially optimized software contribute to longer runtimes. The Skyline also offers 15W wireless charging (magnetic, Qi2) and 5W reverse wireless charging, features absent on the 12R.

Buying Guide

Buy the HMD Skyline if you need a phone that will reliably last through a full day and beyond, and value long-term battery health over peak performance. It’s ideal for users who prioritize efficiency and aren’t demanding gamers or power users. Buy the OnePlus 12R if you prefer a snappy, responsive experience for demanding tasks like gaming and video editing, and appreciate the convenience of incredibly fast 100W charging, even if it comes at the cost of slightly reduced battery endurance.

Frequently Asked Questions

❓ Does the Snapdragon 7s Gen 2 in the HMD Skyline struggle with demanding games like Genshin Impact?
While the Snapdragon 7s Gen 2 is a capable chip, it will likely require reduced graphics settings and frame rate caps to achieve a smooth experience in graphically intensive games like Genshin Impact. The OnePlus 12R’s Snapdragon 8 Gen 2 will handle these titles with ease at higher settings.
❓ How does the 100W charging on the OnePlus 12R affect long-term battery health?
While 100W charging is incredibly fast, it can potentially contribute to faster battery degradation over time. OnePlus employs charging algorithms designed to mitigate this effect, slowing down the charging rate as the battery nears full capacity. However, the HMD Skyline’s slower 33W charging is generally considered gentler on the battery in the long run.
❓ Is the lack of wireless charging on the OnePlus 12R a significant drawback?
For users who frequently utilize wireless charging, the absence of this feature on the 12R is a notable omission. The HMD Skyline offers both magnetic and Qi2 wireless charging, providing added convenience. However, the 12R’s incredibly fast wired charging may offset this drawback for many users.
