Microsoft Lumia 950 XL is official: liquid-cooled Snapdragon 810 SoC, 5.7-inch OLED display, runs Windows 10 Mobile

The Lumia lineup needed a flagship smartphone and it needed it badly. It needed a phone to succeed the 18-month-old Lumia 930, a phone to show that Windows Phone is still alive and kicking. Well, that's the kind of phone we got today. The Microsoft Lumia 950 is now official, and burdened with the task to show us what Windows 10 for Mobile has to shine with. 

But the Lumia 950 was not the only phone shown off on stage during Microsoft's media event. Along with it was announced the Microsoft Lumia 950 XL – a larger, more powerful version of the Lumia 950, and one that will draw the attention of those who are into extra-large handsets. Yup, the Lumia 950 XL is what some would call a phablet.


Needless to say, the Lumia 950 XL is a rather large smartphone. It is 151.9mm tall and 78.4mm wide, which makes it about as large as a Galaxy Note5. Also, it is 8.1mm thick, as long as you don't count the slight camera hump at the back.

On-screen navigation buttons are present on the Lumia 950 XL, whether you like it or not. Naturally, the power and volume keys are physical and located on the side. Interestingly, it appears that the elongated power key is positioned in the middle, with the volume up and volume down buttons placed above and below it respectively. A dedicated camera button has been also thrown in.

The back of the Lumia 950 XL is made of plastic and can be removed, although the battery is fixed and not user-replaceable. Only two colors for the handset have been announced so far – white and black.


The Lumia 950 XL stands out with its large, 5.7-inch display, protected by a layer of Gorilla Glass 4. Microsoft has spared no expenses here as the OLED screen packs 1440 by 2560 pixels for a pixel density of 518 PPI. Microsoft's Glance Screen tech is also on board, allowing you to view notifications by simply taking a look at your phone, without touching a button. The good old ClearBlack technology minimizes the screen's reflectance for better outdoor visibility. Speaking of outdoor visibility, a high brightness mode is triggered when needed. 

Processor and memory

Under the hood of the device is the controversial, but still powerful octa-core Snapdragon 810 SoC running at up to 2.0GHz. Overheating issues are expected to be non-existent thanks to the liquid cooling technology that Microsoft has built in. The latter has been inspired by the cooling system found in the Surface Pro 3, Microsoft brags. 

For some reason, Microsoft isn't saying how much RAM has been packed inside the Lumia 950 XL. (UPDATE: The phone comes with 3GB of RAM on board.) What we do know, on the other hand, is that storage space stands at 32GB. Neither more, nor less. While 32 gigs should be enough for the needs of the typical consumer, the slot for microSD cards allows you to add extra storage.

Software and features

Naturally, the Lumia 950 XL runs Windows 10 Mobile out of the box. In other words, you get to enjoy features like Cortana – Microsoft's intelligent virtual assistant. OneDrive, Skype, and Office are also baked into the experience. And no less importantly, Microsoft's new web browser is on board, built from the ground up to replace Internet Explorer and to deliver a top-notch web experience.

While the Lumia 950 XL does not have a fingerprint scanner, it brings along Microsoft's Hello identification system, albeit in beta form. Simply put, the phone looks for its owner when it is picked up and unlocks if they're recognized. No need to press a button. 

Then there's Continuum – a feature that truly separates the Lumia 950 XL from other phablets. Basically, you may hook up the smartphone to an external monitor, a keyboard, and a mouse for desktop PC-like productivity. The new tech was demonstrated on stage and it looked pretty handy. But there's a catch. You'll need a Microsoft Display Dock to take advantage of Continuum. It plugs into the 950 XL's USB Type-C port, providing the necessary connectors and ports for hooking up the handset to various peripherals. 


Lumia phones are known for their capable cameras, which is why the expectations for the PureView camera on the Lumia 950 XL are set high. With 20MP of resolution (at 16:9 ratio), ZEISS optics, and 5th generation optical image stabilization, we're promised great photos even in poor lighting conditions. On top of that, an innovative triple LED flash is present. Using three different LEDs is meant to produce better, more natural colors and skin tones when the flash is used. You also get a 5MP front-facing cam for selfies.

Videos can be recorded at up to 4K resolution for outstanding details, while the four microphones capture rich, high-fidelity sound. However, it is rather odd that we don't see any fancier modes present on the Lumia 950 XL. For example, 60fps video mode isn't listed in the phone's specs. Slow-motion mode is absent as well.

Connectivity and battery life

As far as connectivity goes, the Lumia 950 XL has not one but two adaptive integrated antennas to improve reception, depending on how the handset is being held. And on its bottom is a USB Type-C connector – one in which USB Type-C cables go either way. Just keep in mind that Type-C is incompatible with the widespread Micro USB cables of today. Fast charging is on board – a 30-minute charge from the stock charger should get you from 10% to over 50% battery capacity. Or you may recharge the phone's battery wirelessly. Speaking of the battery, it is removable and has a capacity of 3340mAh.

Price and release date

The Lumia 950 XL won't come cheap. Microsoft will release the smartphone in November for a price of $649 off-contract. As of this writing, not a single U.S. carrier has announced plans to release the phone on its network. Still, we do expect a launch in parts of Europe, where Lumia phones are enjoying slightly better popularity.

Why does the article wrongly state the battery isn't replaceable?

I mean if the two SIM cards, the two lines can roll over think about what a small business can do with that pone. It is the perfect business phone.

Some have said that it is dead on arrival but I disagree. It looks like an exciting proposition and I will try it. No one mention that it has two SIMS and this phone and the new $400 Motorola put Galaxy Note on notice. The design is nice. The screen ratio is on a part with the Motorola and the Note and put the iPhone plus to shame.

Well, according to Verizon's Twitter account there is no word on whether on not they will carry either phone. I really hope they do because I don't want to switch but I really, really want the XL.

I don't personally see where there is $200 of additional value over something like the Nexus 6P. continuum is great, but in its infancy; the app market is improving, but still trailing.

Nexus 6p doesn't have a pureview 20MP camera, removable battery, iris scanning, etc...

Honestly if Microsoft were to make a phone with 64 GB of storage and 4 GB of RAM and an Intel Processor, while making continuum give a complete desktop experience, even if it was priced higher (though specs-wise it isn't a huge difference) I'm sure those would sell like cupcakes. People want to streamline their devices, and nothing quite says "streamline" like having your laptop and phone be 1 device

It seems that Microsoft will be the first to tame the Snapdragon 810 with this liquid cooling strategy. The Z5 does not have liquid cooling, it is stated nowhere, they used thermal pipes and thermal paste.

...the phone is entire too small to have REAL liquid cooling. You need an intercooler and a fan for that my friend. I think the thermal pipes and paste may be only the lines the same thing thing they did here. They just have a COOLER name for it...heh...

We will find out when the first teardown of the phone occurs.

But with the vast heating issues it has I guess it's not working that well for Sony.

That occurs on the Z5C if I am not mistaken and it's only a few. No news on the Z5 and Z5 premium.

Funny you believed what PA has posted days ago regarding Z5 Compact touchscreen issues where overheating is not the real deal.

Very nice but I was more interested in the camera performance and actual availability.

This is a bit nicer than I expected. But there is no mention of stereo speakers at all which I use allot for watching video. Also the looks are just average. So it probably comes down to this or Sony Z5 Premium. I expect the Sony to cost $200 more but the looks seem to be much nicer along with more available apps.

Looking at all angles I am starting to come around to the design here. I'm liking this newer Microsoft

Liquid cooled SN810?! interesting. Has someone finally tamed the beast?

I think the writer was pretty much over excited by the announcement of this phone. How come Lumia Icon became 18 years old?....

Another smash hit by microsoft's mobile team. I'm sure these will set cash registers on fire..........

Such a huge camera hump. I hope Microsoft justified it by creating the best smartphone camera ever. Every single Major Phone manufacturer step up their game in their camera department ( Except HTC of course ) this year. Gone with the days when Nokia/Lumia devices used to be undisputed camera kind in Photography. If Microsoft don't bring some awesome camera than this phone will be another forgetful windows phone.

Huge camera hump? Wtf are you smoking? There is almost zero camera hump, unlike almost every other recent phone
