Display Comparison

The Lumia 950 XL boasts an 'infinite' nominal contrast ratio, though real-world measurements show 3.837 under sunlight. This suggests excellent black levels in ideal conditions. However, the iPhone 6s Plus, with a 1382:1 nominal contrast ratio and 3.530 under sunlight, still delivers a very respectable visual experience. While the Lumia’s theoretical advantage exists, the practical difference is likely minimal for most users. Both displays perform similarly in bright sunlight. The lack of information on panel technology (OLED vs LCD) for the Lumia hinders a deeper analysis, but the iPhone 6s Plus utilizes an LCD panel.

Camera Comparison

Both devices offer photo and video capabilities, but detailed sensor information is absent. The Lumia 950 XL gained recognition for its image processing and low-light performance, leveraging Microsoft’s computational photography. However, the iPhone 6s Plus consistently delivered reliable and natural-looking images. Without specific sensor size or aperture data, a definitive camera comparison is difficult. The iPhone’s video recording capabilities were generally considered superior at the time of release, offering better stabilization and dynamic range.

Performance

The chipset architectures represent a fundamental difference. The Lumia 950 XL utilizes a Qualcomm MSM8994 Snapdragon 810, an octa-core processor with a split core configuration (4x1.5 GHz Cortex-A53 & 4x2.0 GHz Cortex-A57). This contrasts sharply with the iPhone 6s Plus’s Apple A9, a dual-core 1.84 GHz Twister processor. Despite the core count disparity, the A9, built on a 14/16nm process (depending on the manufacturer), demonstrates superior single-core performance and efficiency. The Snapdragon 810, fabricated on a 20nm node, was known for thermal throttling under sustained load, a problem the A9 largely avoids. This translates to a smoother, more consistent experience on the iPhone, particularly during demanding tasks.

Battery Life

The iPhone 6s Plus significantly outperforms the Lumia 950 XL in battery endurance, achieving 85 hours versus the Lumia’s 62 hours. This difference is substantial and translates to a full day of additional use for the iPhone. The Lumia 950 XL supports 18W wired charging and Qi wireless charging (market dependent), while the iPhone 6s Plus offers slower wired charging and lacks wireless charging. The iPhone’s superior battery life, despite a potentially smaller capacity, is a key advantage.

Buying Guide

Buy the Microsoft Lumia 950 XL if you are a tinkerer interested in exploring alternative mobile operating systems, specifically Windows 10 Mobile, and value a potentially higher display contrast ratio. Buy the Apple iPhone 6s Plus if you prioritize battery life, a more polished user experience, and access to a wider range of (albeit older) apps, even with the limitations of an aging iOS version.

Frequently Asked Questions

❓ Is the Snapdragon 810 in the Lumia 950 XL known to overheat during prolonged use?
Yes, the Snapdragon 810 was notorious for thermal throttling. While the Lumia 950 XL included cooling measures, sustained gaming or video recording could still lead to performance drops as the chip heated up. This is a significant disadvantage compared to the more thermally efficient A9 in the iPhone 6s Plus.
❓ What is the current software support situation for the Lumia 950 XL?
Microsoft officially ended support for Windows 10 Mobile, meaning the Lumia 950 XL no longer receives security updates or feature enhancements. While community efforts exist to maintain functionality, the operating system is increasingly vulnerable and app compatibility is limited. The iPhone 6s Plus, while also running an older iOS version, still benefits from some level of continued security patching.
❓ Does the lack of wireless charging on the iPhone 6s Plus significantly impact its usability in 2024?
While wireless charging is convenient, the iPhone 6s Plus’s excellent battery life mitigates the impact of its absence. The need to plug in less frequently offsets the convenience of wireless charging for many users. Furthermore, the iPhone 6s Plus supports fast charging with a compatible adapter, reducing charging times.
