Both handsets pack 8 GB of expandable storage space. Right out of the box, the Lumia 640 and Lumia 640 XL come with Windows 8.1. Owners can still update their devices to Windows 10, whose release date is pending. Windows 10 is expected to start hitting shelves this coming summer.
The main difference between the Lumia 640 and Lumia 640 XL is their screens. The Lumia 640 has a 5-inch display with 720x1280 pixels, while the Lumia 640 XL sports the slightly larger 5.7-inch display with 720p graphics.
Other differences include the camera and battery capacity. The Lumia 640 has an 8 MP rear camera, along with a 0.9 MP forward-facing camera. On the other hand, the Lumia 640 XL has the higher-res 13 MP rear camera, along with a 5 MP front camera.The Lumia 640 has a 2500 mAH battery while the Lumia 640 XL has the 3000 mAH battery.

Under the hood, the Lumia 640 and Lumia 640 XL come with Cortana - Microsoft's proprietary digital assistant who organizes and keeps track of the user's daily life. The software is named for the iconic artificial-intelligence character from Microsoft's Halo videogame series. Cortana is expected to be a feature in all major Microsoft devices sometime in the future.
Meanwhile, the Lumia 640 and Lumia 640 XL debuted earlier this year in March, at the 2015 Mobile World Congress in Barcelona, Spain. At this time, the phones are only available in the UK and India. Even so, the supply situation will likely change in the weeks ahead.
