Microsoft Lumia 950 XL review: The Master Chief

Display

The Lumia 950 XL's display is half an inch bigger than the one on the Lumia 950, but it keeps the same Quad HD resolution and uses a similar premium AMOLED panel. With a diagonal of 5.7-inches the screen is quite big, but thanks to the high resolution, the pixel density is superb at 518ppi.

Looking at it from a side angle, the screen on the Lumia 950XL gets a slight greenish color cast, which the Lumia 950 doesn't have.

Similarly to the Lumia 950 however, the Lumia 950XL has only average maximum brightness (335nits) if you have the brightness control set to manual, but as soon as you switch to Auto, the phone will push the brightness all the way up to 705nits given the environment is bright enough. Both numbers are slightly higher than what we measured on the Lumia 950.

The screen features what used to be Nokia's ClearBlack tech - a polarization filter that's used to reduced glare (something like how polarized sunglasses work). That along with the Auto brightness peaking in bright light means the screen should be more readable in bright light and indeed, the Lumia 950 XL model scores great in our sunlight chart.

Another positive remark we have about the screen is the excellent color rendering. The average DeltaE is only 1.6 is certainly among the lowest average deviations we've seen on a mobile phone - it's even lower than the Lumia 950. Furthermore, the highest recorded deviation is only 2.9 - an impressive score indeed. You have got to remember that anything below 3 is considered calibration-level color accuracy so we're really happy with the fact that Microsoft provides such color accuracy out of the box.

Microsoft has also supplied the Lumia 950 XL with its Color Profile app that lets you tune the saturation and color balance to your liking.

Battery life

The Lumia 950 XL comes powered by a beefy 3,340 mAh battery, 10% bigger than the one inside the Lumia 950. The phone supports fast charging and can recharge up to 50% of the battery capacity in just 30 minutes. Wireless charging is available, too.

The more demanding chipset and bigger screen didn't give us indications for a better battery endurance than the Lumia 950, yet it happened.

The Lumia 950 XL scored an overall endurance rating of 62 hours, while it did great on all three standalone tests. The standby performance turned out below average though at about 6 and a half days, and thus it played a great part in lowering the expected overall score.

The 62h rating means you can count on two and a half days if you do an hour each of calling, browsing and video playback a day. Opting to put a second SIM slot almost halves the standby time, which lowered the final endurance rating down to 47 hours.

Such usage pattern is of course entirely artificial, but we've established it so our battery results are comparable across devices.

Our proprietary score also includes a standby battery draw test, which is not featured in our battery test scorecard but is calculated in the total endurance rating. Our battery testing procedure is described in detail in case you want to learn more about it.

Connectivity

The Lumia 950 XL supports 12 or 14 LTE bands (market dependent), there is rich 3G and quad-band GSM support, too. The phone uses one or two nano-SIM cards to tap to cellular networks.

The rest of the wireless connectivity features include dual-band Wi-Fi a/b/g/n/ac support. There is also support for Bluetooth 4.1, GPS and GLONASS, plus an FM radio. Wireless screen mirroring is available via the Miracast protocol.

The Lumia 950 XL supports USB Type-C - it's the new reversible connector for USB that builds on top of USB 3.1. If you like to use USB OTG or USB Host, you should either get the Microsoft's Display Dock or other compatible accessory or adapter.

The Microsoft Display Dock

The dock also allows you to connect the phone to an external monitor and is the backbone for enabling the full-blown Windows Continuum experience. Make note that you can also use Continuum over the standard wireless Miracast protocol or connect the phone directly to the display via a USB-C to HDMI adapter. In these cases however, you would not be able to use a wired mouse and keyboard or enjoy the USB host functionality the dock provides. You could use a wireless mouse and keyboard that connect over Bluetooth.

We'll discuss Continuum more in our dedicated section.

Windows 10, by the way, offers a very handy app called Gadgets, which is very similar to Sony's Smart Connect app and allows you to automate tasks based on the accessories connected to the phone.

Gadgets app

The Gadget's app allows you to set your device to do a variety of things - like launch an app - whenever you connect an accessory like a headset, dock or a charger.
