China’s Gionee is already holding that crown with its 5.55mm-thin Elife S5.5 model, but that apparently is not enough.
The company is teasing the device on Chinese social media. Said teaser showcases handset phone thinness champions from the past, including the Motorola V8, Apple iPhone 4, Motorola XT910, and Gionee’s own Elife S5.5.
No word whether this new phone will ever make it to the Western hemisphere. What’s more, a device that is 5mm thin will most certainly have a downside in the form of shorter battery life.
