Huawei has kicked off the quad-core announcement party by revealing the Huawei Ascend D Quad right here in Barcelona, making it the world’s fastest smartphone (so far).

Instead of being powered by Nvidia’s Tegra 3 silicon, the K3V2 quad-core chip on the Huawei Ascend D Quad is custom made by the company itself and boasts up to 30% energy savings.

The Huawei Ascend D Quad crams in a 4.5-inch 720p screen, a quad-core 1.5GHz processor, 5.1 Dolby surround sound and 8MP camera with 1080p video recording into an 8.9mm thin body, while running Android 4.0 Ice Cream Sandwich.

A 1,800mAh battery should keep the Huawei Ascend D Quad chugging along for longer than your average pocket powerhouse, or you can opt for the 10.9mm thin Huawei Ascend D Quad XL which boasts the same specs but packs in a whopping 2,500mAh battery which provides two to three days of usage.

You can snap up the Huawei Ascend D Quad in the Asian, EU, UAE and US from April and although no pricing information has been released as of yet, we’ll be sure to keep you updated.

We’re just finishing off our ham and cheese buffet here in Barcelona before heading over to the HTC event a little later on so keep your eyes and ears open for more mobile news very soon.
