Microsoft Lumia 950, Lumia 950 XL, Lumia 550 Images and Specifications Leak

Microsoft earlier this month was rumoured to launch its Lumia 950 and Lumia 950 XL in October. However, the company might now also be launching a third smartphone - Lumia 550 - alongside with the duo. The three handsets' specifications were recently revealed in leaked slide images. Also, rendered CAD images of both Lumia 950 (seen above) and Lumia 950 XL popped up online, giving us an in-depth idea on their hardware design.

The details of three smartphones were leaked last week on Facebook (via GSMArena) in images purported to be internal company presentation slides. As per the leak, the Microsoft Lumia 950 XL would feature a 5.7-inch QHD display; a Qualcomm Snapdragon 810 SoC; 32GB of inbuilt storage, which can be further expanded via a microSD card; a 20-megapixel PureView rear camera with triple LED flash; a 5-megapixel front-facing camera; a USB Type-C port; an Iris Scanner, and a 3300mAh battery with support for Qualcomm's Quickcharge tech and Qi Wireless charging.

The smaller Lumia 950 would be sporting a 5.2-inch QHD display, hexa-core Qualcomm Snapdragon 808 SoC; and a 3000mAh battery. The rest of the specifications of the handset matches with that of Lumia 950 XL.

The unannounced Lumia 550, as per the leaked slides, would feature 5-inch HD display with Corning Gorilla Glass 3 coating; a quad-core Qualcomm Snapdragon SoC clocked at 1GHz; 1GB RAM; and 8GB of inbuilt storage, which can further expand via a microSD card (up to 128GB); a 5-megapixel autofocus rear camera with LED flash; a 2-megapixel front-facing camera, and a 1905mAh battery.

In a separate leak over the weekend, the Microsoft Lumia 950 and Lumia 950 XL render images showed up on the Web. The renders give details on smartphones' dimensions and a better look on their design profiles.

As per the leaked slides by @Onleaks, the Lumia 950 XL will measure 151.9x78.4x7.8mm. The smartphone's thickness reaches 9.9mm including the rear camera bump. If the leaked dimensions are true, the handset would be slightly shorter and wider than the Samsung Galaxy Note 5 (153.2x76.1x7.6mm). The Lumia 950 XL would be sporting power, volume, and camera buttons at the right side, USB port at bottom, and a headphone slot at the top.

The Lumia 950 features almost a similar design profile but a slightly different rear camera setup design. While the Lumia 950 XL features a bigger circular camera setup like Lumia 1520, which also includes the LED flash, the Lumia 950 sports a smaller circular setup with LED flash placed outside the module.

The three smartphones are expected to launch parallel to Microsoft Band 2 and Microsoft Surface Pro 4 on October 6 at the firm's event in New York City.
