Microsoft Lumia 950

  • More compact and pocketable design.
  • Slightly lower price point (likely at launch).
  • Still offers flagship-level features.

  • Inferior battery life compared to the XL.
  • Less powerful processor for demanding tasks.
  • Lower sunlight contrast ratio.

Microsoft Lumia 950 XL

  • Significantly longer battery life (62h endurance).
  • More powerful Snapdragon 810 processor.
  • Better sunlight readability with higher contrast ratio.

  • Larger and less pocketable form factor.
  • Potentially higher price point (at launch).
  • Larger size may be less comfortable for one-handed use.

Display Comparison

Both the Lumia 950 and 950 XL boast displays with an 'Infinite' nominal contrast ratio, indicating excellent black levels. However, the 950 XL edges out the 950 in sunlight readability with a contrast ratio of 3.837 compared to the 950’s 3512. While both offer a similar visual experience indoors, the XL’s superior sunlight contrast makes it more usable in bright outdoor conditions. The difference in screen size isn't specified, but the 'XL' designation implies a larger viewing area, impacting media consumption and productivity.

Camera Comparison

Both devices share the same 'Photo / Video' camera capabilities, suggesting similar image sensor technology and software processing. However, details regarding sensor size, aperture, and optical image stabilization (OIS) are absent. Given the flagship positioning, it’s reasonable to assume both phones feature high-quality cameras capable of capturing detailed images and videos. Without further specifications, a definitive camera comparison is impossible, but the XL’s processing power *could* contribute to faster image processing and potentially better low-light performance.

Performance

The core difference lies in the chipset: the Lumia 950 utilizes the Qualcomm MSM8992 Snapdragon 808, a hexa-core processor, while the 950 XL features the MSM8994 Snapdragon 810, an octa-core processor. The 810’s octa-core configuration (4x1.5 GHz Cortex-A53 & 4x2.0 GHz Cortex-A57) provides a performance boost over the 950’s (4x1.4 GHz Cortex-A53 & 2x1.8 GHz Cortex-A57), particularly in multi-threaded tasks. While both are built on a 20nm process, the 810’s additional cores translate to smoother multitasking and improved gaming performance. The 950 XL is the clear winner for users prioritizing speed and responsiveness.

Battery Life

The Lumia 950 XL’s 62-hour endurance rating significantly surpasses the Lumia 950’s 48-hour rating. This substantial difference is a direct result of the XL’s larger battery capacity, though the exact mAh isn’t specified. Both devices support 18W wired charging and Qi wireless charging (market dependent), offering convenient charging options. The XL’s extended battery life is a major advantage for users who frequently travel or rely heavily on their smartphone throughout the day.

Buying Guide

Buy the Microsoft Lumia 950 if you prioritize a more pocketable form factor and are content with slightly less demanding performance. It’s ideal for users who primarily use their phone for communication, basic photography, and light web browsing. Buy the Microsoft Lumia 950 XL if you prioritize battery life, smoother multitasking, and a more immersive media consumption experience. This is the phone for power users and those who frequently engage in gaming or resource-intensive applications.

Frequently Asked Questions

❓ Does the Snapdragon 810 in the Lumia 950 XL suffer from throttling under sustained load?
The Snapdragon 810 was known to experience thermal throttling in some devices. However, Microsoft’s implementation and the XL’s larger chassis may have mitigated this issue to some extent. While not definitively confirmed, the XL’s superior cooling capabilities likely resulted in less aggressive throttling compared to other 810-powered phones.
❓ Given the age of these devices, is finding replacement batteries or repairs feasible?
Finding replacement parts for the Lumia 950 and 950 XL is becoming increasingly difficult. As these devices are no longer officially supported, sourcing batteries or professional repairs may require relying on third-party vendors or DIY solutions, which carry inherent risks. The enthusiast community may offer some resources, but availability is limited.
❓ How does the Windows 10 Mobile operating system impact the user experience on these devices today?
Windows 10 Mobile is no longer actively developed or supported by Microsoft. This means users will not receive security updates or new features. While core functionality may still work, compatibility with modern apps is limited, and the overall experience is significantly hampered compared to current Android or iOS devices. These phones are primarily of interest to collectors or those seeking a nostalgic experience.
