The one year old Lumia 640XL is fighting against the freshly released Lumia 950XL flagship, but with its specs, it doesn’t have a chance to defeat the new phablet. The only things these devices have in common are the 5.7-inch screen and the plastic bodies with similar designs.
Designs, Dimensions and Displays
For starters, the Lumia 640XL is thicker at 9mm and it’s much taller at 157.9mm, but it has also a plastic back with slightly curved edges and rounded corners. It has a rear camera in the top center with the LED flash above it, while the bezels are quite thick. The color options for this model are Matte cyan, Orange, Black, Matte white and Glossy white, the phone weights 171 grams and its screen is IPS LCD, supporting a resolution of 720 x 1280 pixels at 259 ppi.
The Lumia 950XL is available only in two colors: Black and White and its body is slimmer at 8.1mm, while it has a height of 151.9mm and a weight of 165 grams. The phablet has a larger circular camera with Zeiss lens, which has a triple-LED flash. This time, Microsoft has used Samsung’ AMOLED panel, which has a higher resolution of 1440 x 2560 pixels, which clearly makes the screen sharper and brighter, as the resulted pixel density is 518 ppi and you will see the difference when putting the two devices side by side.
The Lumia 640XL is considered a mid-range phone which is powered by a weak quad-core 1.2 GHz Cortex-A7 based on a Qualcomm MSM8226 Snapdragon 400 chipset, which is backed by Adreno 305 graphics and 1GB of RAM and it supports a low internal memory of 8GB whose capacity can be increased up to 128GB.
The Lumia 950XL comes with the controversial Qualcomm MSM8994 Snapdragon 810 chipset which has a quad core processor clocked at 1.5GHz and a second quad core processor clocked at 2GHz, but this is the second generation, much improved, so it doesn’t heat up badly like the original chipset. The device houses also 3GB of RAM and the internal memory can be increased from 32GB to 200GB. This model comes loaded with the new Windows 10 OS and has a feature called Continuum, which allows the users to transform the phone into a computer, by attaching an optional display dock.
Cameras and Batteries
The old 640XL came with a 13MP main shooter with Carl Zeiss optics, autofocus, LED flash and a 1/3” sensor size, while its front camera was 5MP. Microsoft has made some significant improvements to the camera software and increased the resolution of the primary camera of the 950XL, which supports now 20MP. In addition to the basic features, the phablet offers OIS, a triple-LED RGB flash and it uses the PureView technology, which takes amazing shoots. Also, the phone can record 4K videos and when zooming into the images, the details are very clear.
Both devices have removable batteries, but the 640XL comes with a smaller cell of 3000mAh, while the 3340mAh battery of the 950XL supports quick charging (charging the device from 0 to 50 percent in thirty minutes) and Qi wireless charging.
