BARCELONA, Spain — Microsoft introduced a couple of new mid-market Windows phones here in Spain today: the Lumia 640 and Lumia 640 XL.

The phones ship with Windows Phone 8.1, but can be upgraded to the Windows 10 OS when it becomes available later this year. Microsoft demonstrated the features of Windows 10 publicly for the first time here in Barcelona.

The new phones are powered by a Qualcomm Snapdragon processor — a quad-core CPU running at 1.2GHz. They also offer plenty of onboard memory — 1GB.

The Lumia 640’s display is 5 inches, while the 640 XL’s is 5.7 inches. The 640 has a 2500 mAh battery, and the XL has a larger 3000 mAh battery.

Both the new phones have LTE radios inside, and dual-SIM models are available, Microsoft said.

Windows 10 will add new universal apps like Office, Mail and Calendar, and Photos, as well as Skype messaging to Microsoft phones. The new OS will also offer a newly designed web browser and broader use of the Cortana personal assistant.
