The Lumia 950XL has recently starred in what looks to be the handset's final leaked photo before it's unveiling during Microsoft's Windows 10 devices media event on Oct. 6.

Trusted gadget leaker Steve Hemmerstoffer, also known in tech circles as @OnLeaks, flashed the last-minute image on his official Twitter account.

The live still showed the Lumia 950XL without its back cover, revealing the handset's removable battery. As with most leaks, the latest discovery presented more questions than answers.

A label on the handset's battery reads "TYPICAL 3340mAh." However, the fonts of the graphemes are noticeably inconsistent.

Furthermore, it's seemingly redundant for Microsoft to print out the capacity on the front of the battery when detailed information about the piece of hardware can most likely be found on its opposite side.

GSM Arena speculated that whoever captured the photo already knew of the handset's battery capacity and just wanted to include the information on the image.

At any rate, the more important reveal of the day is that the Lumia 950XL has been confirmed to sport a removable battery, a feature that is becoming rare among next-generation flagship smartphones.

According to PC Advisor, the other freshly rumored specs of the Lumia 950XL include a 5.7-inch QHD display, 3GB of RAM and 32GB internal memory expandable up to 2TB via micro-SD support.

The handset is powered by Qualcomm's octa-core Snapdragon 808 processor and runs on the new Window 10 Mobile operating system.

It is fitted with a 20-megapixel Pure View rear camera with Zeiss optics, OIS and triple-LED flash paired with a five-megapixel front-facing unit.

The upcoming Windows 10 Mobile flagship phablet also tows support for Continuum via Microsoft Display Dock.

Windows 10 Mobile is distinct from other smartphone platforms since it is not a mobile-exclusive operating system. In fact, it runs homogenously with the Windows 10 running on PC, Cubic Lane reported.

To put that in perspective, apps on Windows 10 desktops can function the same way on Windows 10 smartphones without Microsoft needing to create two separate versions of one particular app. The tech giant calls these adaptable apps as Universal Apps. 

The smooth transition is possible through a feature in Windows 10 known as Continuum. The said feature lets Universal Apps go back and forth from smartphone to desktop displays. This means that through Universal Apps and Continuum, Windows 10 smartphones can run similar to Windows 10 desktops once the smartphone is plugged into a larger screen.

Neuro Gadget pointed out that the Lumia 950XL also has an iris-scanning technology for Windows Hello and support for Qi wireless charging.
