Microsoft has yet to reveal official information about their rumored upcoming smartphones, the Lumia 950 and the bigger Lumia 950 XL, at the company's event early next month. However, the devices' prices were reportedly leaked online. 

Phone Arena recently spotted a posting on the Spanish gadget retailer website Ecomputer.es, where the price list for the latest Lumia phones were supposedly revealed. However, the post has already been taken down from the website. 

Based on the post, the soon-to-be released dual-SIM Microsoft Lumia 950 will have a €659 ($736) price tag while the Microsoft Lumia 950 XL will be available for €749 ($838).  However, the posting did not mention when the devices will be released to the public. 

According to reports, the new Lumia 950 is believed to have a 5.2-inch touchscreen display that has 1440 x 2560 pixel QHS resolution. Under the hood, several reports say that it will be equipped with a Qualcomm Snapdragon 808 chipset combined with 3 GB of RAM, an expandable 32 GB internal storage, and a 3000 mAh battery capacity. 

Meanwhile, the Microsoft Lumia 950 XL will possibly come with a 5.7-inch QHD display, a Qualcomm Snapdragon 810 chipset that is combined with 3 GB of RAM and 32 GB of internal storage that can be expanded using the built-in microSD card slot. The battery of the device is said to have a larger 3300 mAh battery capacity. Both smartphones are expected to have 20 MP PureView primary cameras as well as a 5 MP selfie shooter on the front. 

Both Lumia handsets are said to run on Microsoft's newest Windows 10 Mobile upon release. 

Microsoft has yet to confirm if the leaked reports are accurate.
