Qualcomm detailed its upcoming Snapdragon 800 processor at CES last month but apparently it left a couple of key features under wraps. Now, with Mobile World Congress around the corner, the company is ready to share a little more with a blog post announcing Quick Charge 2.0 and Voice Activation.

The first of these features represents the natural evolution of Qualcomm's existing Quick Charge 1.0 technology, available on Snapdragon-powered devices like the Galaxy S III, Nexus 4, and Lumia 920. In a nutshell, version 2.0 is said to charge devices 75% faster than those without the technology, an improvement over the 40% figure touted by Qualcomm for Quick Charge 1.0. The technology requires an optimized charger and is baked into the Snapdragon 800, but it's not exclusive to Qualcomm-based hardware. Quick Charge 2.0 will be offered as a stand-alone circuit for other companies to use and could charge even laptops demanding up to 60W of energy.

To put things in perspective Qualcomm says its own lab tests show tablets that normally take over 7 hours to charge were able to reach full charge in less than 3 hours with Quick Charge 2.0.

Additionally, the company announced that devices using Snapdragon 800 processors will have an always-on, low-power voice activation feature that will allow users to wake up their phone with a custom voice command. The feature is said to be tailored to each device owner's voice and works even in standby or airplane mode. Once the device is "woken up" it will trigger your phone's voice assistant feature for hands-free control.

Qualcomm says that there are currently more than 55 Snapdragon 800-based devices being developed, with the hardware expected to land sometime in the second half of 2013 or early 2014.
