BARCELONA -- The Microsoft Lumia 640 XL that launched here at Mobile World Congress 2015 isn't only bigger than the 5-inch Microsoft Lumia 640. It also has a more upmarket camera and a slightly larger battery.

The phone starts with a supersize 5.7-inch display with a 720p resolution. This is on the low end for a screen this big. The Windows Phone 8.1 OS should look just fine, but photos and videos may look less crisp.

We looked at it in white and blue, but it also comes in bright orange (like, eye-searing) and black. The orange color sports a glossy, high-shine finish while the others are matte. The handset is large, but rounded corners and that polycarbonate material keep it from feeling too slick, at least on the matte versions.

A 13-megapixel rear camera and 5-megapixel front-facing camera both also shoot 1080p HD video.

A Qualcomm Snapdragon 400 processor inside tackles tasks with a 1.2GHz quad-core clock speed. Also inside, a 3,000mAh battery gives the 640 XL a little more juice than the Lumia 640 gets.

Storage is identical between the two phones: 8GB internal storage with 1GB RAM, and up to 128GB on the microSD card. Microsoft also gives you up to 30GB free OneDrive storage for your photos (through camera backup).

We don't have launch details quite yet, but we hear the Lumia 640 XL will come out in early April. Pricing is locked down, though: the 4G LTE Lumia 640 XL will cost $240 or £219. The 3G model, meanwhile, will cost $210, but won't be available in the UK.
