Late September, the specifications for the handsets Lumia 950, Lumia 950 XL and Lumia 550 were leaked online, as our previous report suggests. Then, recently, an official listing for the two high-end phones have been spotted and it was posted on the official Microsoft UK outlet.

According to the report from GSM Arena, the listing was spotted on the official Microsoft UK online store, but, unfortunately, the post is not available anymore and was taken down by the site. Luckily, GSM Arena had managed to take a screenshot of the page and the specifications listed there are similar to the ones that were previously leaked.

As can be seen on the post, the Lumia 950 and 950 XL will both sport in a 20MP rear camera equipped with ZEISS optics technology. Both phones will also come with the same internal memory capacity of 32GB, which can also be expanded using MicroSD card and as what the company wrote on the listing, it can even reach up to 2TB. The maximum expansion though was a huge surprise, to say the least. Other than the same camera and memory storage, these handsets will also run on the latest Windows mobile operating system, Windows 10.

The Lumia 950, as GSM Arena reports, will be running on a Qualcomm Snapdragon 808 CPU, while the Lumia 950 XL is said to come with a much powerful processor from the same manufacturer, Snapdragon 810. The Lumia 950 will sport in a 5.2-inch screen size of WQHD and the XL variant will have a much bigger screen of 5.7-inch with the same display resolution.

The smaller phone is said to come with a battery capacity of 3,000mAh, while the larger one will have 3,300mAh battery unit.

Both of these phones, along with the mid-range one, the Lumia 550, are expected to be unveiled next week, Oct. 6, 2015.
