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 pulls ahead in sunlight readability with a contrast ratio of 3.837 compared to the 950’s 3512. This means the screen remains more visible under direct sunlight. While both share the same resolution, the 950 XL’s larger 5.7-inch display results in a slightly lower pixel density, though this difference is unlikely to be noticeable to most users. The lack of high refresh rate technology is a shared limitation, common for phones of this era.

Camera Comparison

Both devices share the same 'Photo / Video' camera capabilities, suggesting similar image sensor technology and software processing. However, detailed sensor specifications are missing. Given the flagship positioning, both likely featured high-quality sensors with optical image stabilization (OIS). The real-world performance would likely be very similar, with the 950 XL potentially benefiting from slightly faster image processing due to its more powerful chipset. The absence of detailed camera specs makes a definitive comparison difficult, but the overall camera experience should be comparable.

Performance

The core difference lies in the chipsets. The Lumia 950 XL utilizes the Qualcomm MSM8994 Snapdragon 810, an octa-core processor with a combination of Cortex-A53 and A57 cores clocked up to 2.0 GHz. The Lumia 950, conversely, features the MSM8992 Snapdragon 808, a hexa-core processor with a similar core configuration but lower clock speeds (1.8 GHz). This translates to a tangible performance advantage for the 950 XL in demanding tasks like gaming and video editing. The 810’s more powerful GPU handles graphics-intensive applications with greater ease. Both phones utilize a 20nm manufacturing process, but the architectural differences give the 810 the edge.

Battery Life

Battery life is where the Lumia 950 XL truly shines. Its endurance rating of 62 hours significantly surpasses the Lumia 950’s 48 hours. This difference is directly attributable to the XL’s larger battery capacity. Both phones support 18W wired charging and Qi wireless charging (market dependent), offering convenient charging options. The 950 XL’s superior battery life is a critical advantage for users who heavily rely on their smartphones throughout the day, reducing the need for frequent charging.

Buying Guide

Buy the Microsoft Lumia 950 XL if you prioritize extended battery life, demanding multitasking, and a generally more responsive user experience. This phone is ideal for power users and those who frequently rely on their smartphone throughout the day. Buy the Microsoft Lumia 950 if you prefer a more compact form factor and are willing to trade some performance and battery life for increased portability. It’s a good option for users who primarily use their phone for basic tasks like calls, texts, and light browsing.

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 likely mitigated this issue to some extent. While prolonged gaming sessions might lead to some performance reduction, it shouldn’t be a major concern for typical usage.
❓ Is the difference in battery life between the 950 and 950 XL noticeable in everyday use?
Absolutely. The 14-hour difference in endurance rating translates to a significant real-world advantage for the 950 XL. Users can expect to comfortably get through a full day of heavy use without needing to recharge, whereas the 950 might require a top-up in the evening.
❓ Given the age of these devices, are replacement batteries readily available?
Finding original replacement batteries can be challenging. Third-party batteries are available, but their quality and reliability can vary. It's crucial to research reputable sellers and read reviews before purchasing a replacement battery.
