Advancements in technology have allowed smartphone manufacturers to continue to push the envelope when it comes to building thin devices. Such is the case with Oppo's new R5 smartphone which, at just 4.85mm thick, narrowly beats out the 5.15mm Elife S5.1 from Gionee.

Despite its thin profile, the Oppo R5 packs a solid punch in terms of specifications. It features a 5.2-inch AMOLED screen operating at a resolution of 1,920 x 1,080 which is good for a pixel density of 423 pixels per inch. A 64-bit octa-core Qualcomm Snapdragon SoC handles processing duties while a Qualcomm Adreno 330 GPU gets the nod on the graphics side.

Elsewhere, the Android-powered R5 includes 2GB of RAM, 16GB of flash storage, a 13-megapixel rear camera, a 5-megapixel front-facing shooter (both with f/2.0 aperture), an LTE radio and a 2,000mAh battery with Rapid Charge technology that can provide two hours of chat time from a five minute charge and a 75 percent rejuice in half an hour.

The phone weighs just 155g and given how thin it is, there are some sacrifices that have to be made.

There's no micro SD card slot so you'll need to rely on cloud storage for expansion and curiously enough, there isn't a 3.5mm headphone jack either. Instead, Oppo includes a micro USB-to-3.5mm jack should you want to plug in a set for private listening (or use Bluetooth).

The Oppo R5 is slated to ship globally this December in silver, gold and grey priced at $499 sans contract.
