Today, the Caption LAB uploaded a teardown video of Microsoft Lumia 950 XL on YouTube. This 15 – 16 minute video showed the part by part disassembly and assembly of Lumia 950 XL . From that video we can see that there are some interesting things about the device.
Lumia 950 XL was introduced on October 6, through a Microsoft Windows 10 Device event. Microsoft claimed their new flagships – Lumia 950 and 950 XL – use a liquid cooling system to cool off the Snapdragon 808 processor inside. These are the first smartphones using the cooling system, like a PC. It awakes our curiosity, whether the new Lumia is warm or cold?
