Microsoft Lumia 640 XL Arrives Exclusively on AT&T

The Microsoft Lumia 640 XL is the latest in a string of reasons to consider the switch to a Windows phone (Windows 10 is coming!). This new handset arrives in AT&T stores and online Friday, June 26. It will be available for $0 down and 30 payments of $8.34 a month, 24 monthly payments of $10.42 or 20 monthly installments of $12.50.

At 5.7 inches, the Lumia 640 XL is larger than the 5.5-inch iPhone 6 Plus and the same as the Samsung Galaxy Note 4, but it has a relatively lower HD resolution. The new Lumia will run Windows Phone 8.1, bringing you such goodies as Microsoft's Cortana voice assistant, seamless sharing across your PC and phone and new personalization features.

Powered by a quad-core Snapdragon 400 processor with 8GB of storage, the Lumia 640 XL seems light on specs compared to today's leading flagships that pack octa-core chips. However, the Lumia's 3,000-mAh battery is bigger than the one on the Galaxy S6 (2,550-mAh). Samsung's phone provided 8 hours and 32 minutes of endurance, so we'll expect even more from the Lumia.

With a 13-megapixel rear camera and 5-MP front shooter, the Lumia 640 XL should be a solid companion for smartphone photographers. But to see how it stacks up against its competitors, stay tuned for a full review.
