Microsoft has been doing some real hard work to gain a respectable position in the smartphone space. The company's latest devices, Lumia 950, 950XL and Lumia 550, have been a great example of that. But the Redmond-based software titan is not done yet. Rumours have it that another Lumia phone is in the pipeline, and it wears the mid-tier tag in the company's portfolio.

It was recently confirmed that the new phone, the Lumia 650, is going to be an affordable device with a metal body and Windows 10 OS. Now, a fresh report claims to have the final spec-sheet of the rumoured device, which might be launched sometime in the first quarter of this year.

According to Venture Beat, which cited a source with access to a prototype of Lumia 650, the handset is going to feature a 5-inch HD display, 8MP primary camera, quad-core Qualcomm Snapdragon 210 chipset and 1GB RAM.

The report further reveals that Lumia 650 will come with a 2,000mAh battery, which is in fact smaller than the Lumia 550 (2,100mAh) and Lumia 640 (2,500mAh). But Microsoft may have an attractive feature to go with it, as the Lumia 650 will support wireless charging. Another noteworthy mention in the Lumia 650 is its design and the all-metal body, which will certainly appeal to some Lumia fans.

The latest report did not reveal what OS the Lumia 650 runs, but last month's report confirmed it would be powered by Windows 10, joining the small army of devices that currently run the latest OS.

Microsoft has been stringent in releasing the Windows 10 Mobile OS to existing Lumia users. The company has promised it will begin the process "soon". We have already listed the devices eligible to receive the new software. It's only a matter of time before you start getting the notifications for upgrade.
