MOBILE CHIP DESIGNER Qualcomm has announced the next generation of its speedy device charging technology, Quick Charge 2.0.

Set to feature in smartphones and tablets powered by Snapdragon 800 processors, Quick Charge 2.0 is "faster and more flexible" than Quick Charge 1.0, according to Qualcomm, with products featuring the next generation technology charging up to 75 percent faster than products without it.

"In our labs we found tablets that normally take over seven hours to charge were able to reach full charge in less than 3 hours with the Quick Charge 2.0 solution," Qualcomm VP of product management Jim Tran said in a post on the firm's blog.

"While Quick Charge 1.0 technology, with about 10 watts of power, was designed primarily for smartphones and tablets, Quick Charge 2.0 delivers up to 60 watts, not only improving charge times for smartphones and tablets, but adding support for larger mobile computing devices like slim notebooks."

Qualcomm talked up its "little known" Quick Charge 1.0 technology for the first time earlier this month, despite having been developed and integrated a while ago in Snapdragon powered devices such as the Samsung Galaxy S3, the HTC 8X, the Nokia Lumia 920 and the Google Nexus 4 built by LG. Nevertheless. the firm expects that devices and wall chargers carrying Quick Charge 2.0 will be available in early 2014.

For those wondering about backwards compatibility, Qualcomm reassured users that Quick Charge 2.0 devices are designed to play with Quick Charge 1.0 chargers and vice versa, so are all both backward and forward compatible.

"You can use a Quick Charge 2.0 charger with a Quick Charge 1.0 device, since by default the 2.0 charger safely provides only the voltage/power allowed by the 1.0 device," Tran said.

"And while 2.0 devices will ship with 2.0 chargers, 2.0 devices can be charged safely by 1.0 chargers as well, but at '1.0 speed'." µ
