World's thinnest (0.15in) smartphone Vivo X5 Max announced, goes on sale December 22

Chinese manufacturer Vivo officially announced the Vivo X5 Max, an uber-thin smartphone that measures just 0.15in (3.98mm) at its thinnest point and 0.18in (4.75mm) at its chubbiest. With no doubt, this is the world's thinnest smartphone in official existence, besting those Guiness-certified Gionee Elife phones and the newcomer Oppo R5, which happens to be a "whopping" 0.00394in (0.10mm) thicker.

Vivo literally cut many corners to accomplish its ambitions. It designed a motherboard that's only 0.067in (1.7mm) thick, used an exceptionally thin screen assembly that measures just 0.05in (1.36mm), and stuck "the world's thinnest speaker box" at 0.09in (2.45mm) inside. This is made even more impressive by the fact that the Vivo X5 Max somehow retains a dual-SIM slot and a 3.5mm headphone jack at such constraints.

If you've been in the loop, you probably know what the X5 Max has to offer in terms of specs. It has a 5.5-inch 1080p Super-AMOLED screen and runs on a Qualcomm Snapdragon 615 1.7GHz octa-core processor, paired with 2GB of RAM and 16GB of expandable storage. A 13MP rear camera and a 5MP front cam take care of photos, while an Yamaha YSS-205X chip handles sound. The Vivo X5 Max runs Android 4.4.4 KitKat topped off with Funtouch OS 2.0.

The max-thin apparatus will go on sale on December 22, priced at $486 (2998 RMB) in China.
