Microsoft’s mobile business is not doing well as it has encountered a 73 percent decline in the sales of Lumia smartphones in the last quarter. It is being reported that retailers are returning unsold Lumia smartphones to Microsoft because of high inventory levels. Rumors are rife that in order to sell more number of Lumia 950 and 950 XL flagship phones, the Redmond giant will soon start a buy-one-get-one (BOGO) offer.

David Mealo, a Windows developer, has tweeted that Microsoft is soon going to start a BOGO deal to reduce the existing inventory of Lumia 950 and 950 XL smartphones. Mealo has revealed that the BOGO offer will allow buyers of Lumia 950 XL to get a Lumia 950 for free. The rumored promotional offer is expected to start Tuesday.

MS Power User has speculated that if Microsoft is truly going to start a BOGO offer for Lumia 950 XL buyers, it will probably be available only through the Microsoft Store as none of the U.S. carriers are selling the smartphone. At the time of writing, there was no official confirmation on the BOGO offer.

The Lumia 950 and 950 XL were launched in October last year. The Lumia 950 features a 5.2-inch AMOLED screen that supports Quad HD resolution. It is powered by Snapdragon 808 SoC and 3 GB of RAM. It is packed with a 3000 mAh battery.

The Lumia 950 XL is a larger phone that features a 5.7-inch Quad HD resolution supporting AMOLED screen. The Snapdragon 810 SoC and 3 GB of RAM powers the phablet. It features a bigger battery of 3340 mAh battery.

Even though both smartphones differ in display size, chipset and battery, the flagship smartphones running on Windows 10 Mobile OS come with common features like 32GB native storage, microSD slot, Continuum support, 20-megapixel rear camera, 5-megapixel selfie shooter, USB Type-C, and an iris scanner.
